lnav v0.12.3

Features:

Files that contain a mixture of log messages from separate services (e.g. docker logs) can now be automatically de-multiplexed into separate files that lnav can digest.
The log_opid column on log vtables can now be UPDATEd so that you can manually set an opid on log messages that don't have one. Setting an opid allows messages to show up in the timeline view.
The Files panel now has a details view on the right side that shows extra information about the selected file. You can look here for details of why lnav selected a particular log format.
Add support for GitHub Markdown Alerts.
Added the :xopen command that will open the given paths using an external opener like open or xdg-open.
Clicking on a link in a markdown file will open the Actions with the following options:
- opening the link target in lnav or, if it's an lnav script, executing the script;
- opening the target with :xopen;
- or, copying the link to the clipboard.
Added a crash upload command to the management CLI that will upload crash logs to a server for analysis.
Added a :set-text-view-mode command that controls whether file contents, such as markdown, are rendered or shown in their raw state.
Text files with lines longer than 1024 characters will be automatically pretty-printed. You can revert to the raw view using the :set-text-view-mode command. The character limit can be adjusted with the /tuning/textfile/max-unformatted-line-length configuration setting.
Added a pretty_print() SQL function that provides the same functionality as the PRETTY view.
Keymap definitions can now bind to a function key using an identifier that starts with f followed by the number of the function key.
Added log formats for the env_logger and simple_logger Rust crates.
Timestamp formats can now use %j to capture day-of-year values.

Interface Changes:

The "Gantt Chart" view has been renamed to "timeline."
In the timeline view, pressing ENTER will focus on the preview pane, so you can scroll through messages with the selected Op ID.
With mouse mode enabled, CTRL can be used as an alternate to SHIFT when clicking/dragging in the main view to highlight lines. A few terminals capture shift+clicks as a way to select text and do not pass them to the application.
Clicking on an internal link in a Markdown document will move to that section.

Bug Fixes:

Log messages in formats with custom timestamp formats were not being converted to the local timezone.
The timezone offset is now shown in the parser details overlay for log messages.
If a theme does not define cursor-line or selected-text styles, the styles from the default theme will be used.
The first argument to a script is now the full path of the script and not just the script name.

Maintenance:

You can now do an UPDATE on the lnav_top_view SQL view. This makes it easier to write queries that manipulate the current view.
Upgrade to C++17

lnav v0.12.2

Features:

Added mouse support that can be toggled with F2 or enabled by default with: :config /ui/mouse/mode enabled. With mouse support enabled, many of the UI elements will respond to mouse inputs:
- clicking on the main view will move the cursor to the given row and dragging will scroll the view as needed;
- shift + clicking/dragging in the main view will highlight lines and then toggle their bookmark status on release;
- double-clicking in the main view will select the underlying text and drag-selecting within a line will select the given text;
- when double-clicking text: if the mouse pointer is inside a quoted string, the contents of the string will be selected; if the mouse pointer is on the quote, the quote will be included in the selection; if the mouse pointer is over a bracket (e.g. [],{},()) where the matching bracket is on the same line, the selection will span from one bracket to the other;
- when text is selected, a menu will pop up that can be used to filter based on the current text, search for it, or copy it to the clipboard;
- right-clicking the start of a log message in the main view will open the parser details overlay;
- the parser details now displays a diamond next to fields to indicate whether they are shown/hidden and this can be clicked to toggle the state;
- the parser details will show a bar chart icon for fields with values which, when clicked, will open either the spectrogram view for the given field or open the DB query prompt with a PRQL query to generate a histogram of the field values;
- clicking in the scroll area will move the view by a page, double-clicking will move the view to that area, and dragging the scrollbar will move the view to the given spot;
- clicking on the breadcrumb bar will select a crumb and selecting a possibility from the popup will move to that location in the view;
- clicking on portions of the bottom status bar will trigger a relevant action (e.g. clicking the line number will open the command prompt with :goto <current-line>);
- clicking on the configuration panel tabs (i.e. Files/Filters) will open the selected panel and clicking parts of the display in there will perform the relevant action (e.g. clicking the diamond will enable/disable the file/filter);
- clicking in a prompt will move the cursor to the location;
- clicking on a column in the spectrogram view will select it.
(Note that this is new work, so there are likely to be some glitches.)
Added a journald:// URL handler that will call journalctl and pass any query parameters as options. For example, the following command:
```
$ lnav 'journal://?since=yesterday'
```
Will execute the following and capture the output:
```
journalctl --output=json -f --since=yesterday
```
Added the "last-word" line-format field shortening algorithm from @flicus.
Added a stats.hist PRQL transform that produces a histogram of values over time.
The preview for the :open command will now show a listing of archive contents.
Added humanize_id SQL function that colorizes a string using ANSI escape codes.
Added a selected_text column to the lnav_views table that reports information about text that was selected with a mouse. This makes it possible to script operations that use the selected text as an input.
Added breadcrumb as an option to the :prompt command so that the breadcrumb hotkey can be configured.

Interface changes:

The bar charts in the DB view have now been moved to their individual columns instead of occupying the whole width of the view. The result is much cleaner, so the charts are now enabled by default again.
Cursor mode in the main view is now the default instead of using the top line as the focus. You can change back by running:

:config /ui/movement/mode top
In the parser details panel (opened by pressing p), you can now hide/show fields by moving the cursor line to the given field and pressing the space bar or by clicking on the diamond with the mouse.
The sv keymap binds § to focus the breadcrumb bar.

Bug Fixes:

With the recent xz backdoor shenanigans, it seems like a good time to add some checks for data being hidden by escape codes:
- File names with escape sequences are now displayed in quotes with backslash escapes.
- Text that has the same foreground and background colors will have the background set to a contrasting color.
Sub-millisecond time values should now be preserved when displaying JSON-lines logs.
A crash during initialization on Apple Silicon and MacOS 12 has been fixed.
A crash when previewing non-text files.
Optimized ANSI-escape processing.
Various fixes to make lnav usable as a PAGER.

lnav v0.12.1

Features:

Database queries can now be written in PRQL. When executing a query with ;, if the query starts with from, it will be treated as PRQL. The pipeline structure of PRQL queries is more desirable for interactive use since lnav can make better suggestions and show previews of the stages of the pipeline.
Log partitions can automatically be created by defining a log message pattern in a log format. Under a format definition, add an entry into the "partitions" object in a format definition. The "pattern" property specifies the regular expression to match against a line in a file that matches the format. If a match is found, the partition name will be set to the value(s) captured by the regex. To restrict matches to certain files, you can add a "paths" array whose object elements contain a "glob" property that will be matched against file names.

Interface changes:

When using PRQL in the database query prompt (;), the preview pane will show the results for the pipeline stage the cursor is within along with the results of the previous stage (if there is one). The preview works on a limited data set, so the preview results may differ from the final results.
Changed the breadcrumb bar styling to space things out more and make the divisions between items clearer.
The ESC key can now be used to exit the files/filters configuration panel instead of q. This should make it easier to avoid accidentally exiting lnav.
Added some default help text for the command prompt.
Suggestions are now shown for some commands and can be accepted by pressing the right arrow key. For example, after typing in :filter-in the current search term for the view will be suggested (if one is active).
The focused line should be preserved more reliably in the LOG/TEXT views.
In the LOG view, the current partition name (as set with the :partition-name command) is shown as the first breadcrumb in the breadcrumb bar. And, when that breadcrumb is selected, you can select another partition to jump to.
The { / } hotkeys, :next-section, and :prev-section commands now work in the LOG view and take you to the next/previous partition.
The DB view now defaults to not showing bar charts.

Breaking changes:

Many of the lesser used column in the log format tables (e.g. log_tags) have been moved to after the columns defined by the format. These columns are usually NULL and are a distraction when previewing queries.

lnav v0.12.0

Features:

Added a Gantt Chart view to visualize operations over time based on the "opid" in log messages. The view shows the operation IDs, a description of the operation captured from log messages, and a bar representing the period of time that the operation was running.
Added the :sh command and -e option to execute a shell command-line and display its output within lnav. The captured output will be displayed in the TEXT view. The lines from stdout and stderr are recorded separately so that the lines from stderr can be shown in the theme's "error" highlight. The time that the lines were received are also recorded internally so that the "time-offset" display (enabled by pressing Shift + T) can be shown and the "jump to slow-down" hotkeys (s/Shift + S) work. Since the line-by-line timestamps are recorded internally, they will not interfere with timestamps that are in the commands output.
Added a :cd command to change lnav's current directory.
Added support for automatically converting files that are in a format not natively supported by lnav. The new converter section in a log format definition allows you to specify how a file type can be detected and converted. The built-in PCAP support in lnav is implemented using this mechanism.
Added a shell_exec() SQLite function that executes a command-line with the user's $SHELL and returns the output.
Added support for custom URL schemes that are handled by an lnav script. Schemes can be defined under /tuning/url-schemes. See the main docs for more details.
Added docker:// and podman:// URL schemes that can be used to tail the logs for containers (e.g. docker://my-container) or files within a container (e.g. docker://my-serv/var/log/dpkg.log). Containers mentioned in a "Compose" configuration file can be tailed by using compose as the host name with the path to the configuration file (e.g. docker://compose/compose.yaml).
Added an :annotate command that can trigger a call-out to a script to analyze a log message and generate an annotation that is attached to the message. The script is executed asynchronously, so it will not block input and the result is saved in the session. Annotations are defined in the /log/annotations configuration property.
Timestamps with numeric timezone offsets (or Z) are now automatically converted to the local time zone. For example, a timestamp ending in -03:00 will be treated as three hours behind UTC and then adjusted to the local timezone. This feature can be disabled by setting the /log/date-time/convert-zoned-to-local configuration property to false. Timestamps without a zone or have a symbolic zone name (e.g. PDT) are not converted.
Added the SQLite JSON functions to the online help.
Added config get and config blame management CLI commands to get the current configuration and the file locations where the configuration options came from.
When piping data into lnav's stdin, the input used to only be written to a single file without any rotation. Now, the input is written to a directory of rotating files. The same is true for the command-lines executed through the new :sh command. The piped data can be managed using the new piper commands in the management CLI.
The $LNAV_HOME_DIR and $LNAV_WORK_DIR environment variables are now defined inside lnav and refer to the location of the user's configuration directory and the directory where cached data is stored, respectively.
The <pre> and <img> tags are now recognized in Markdown files.
The style attribute in <span> tags is now supported. The following CSS properties and values are supported:
- color and background-color with CSS color names
- font-weight with a value of bold or bolder
- text-decoration with underline
- border-left and border-right with the solid, dashed and dotted line styles and colors.
Added an options column to the lnav_views table to allow more control over overlays.
Added a "Dracula" theme as described at: https://draculatheme.com
Added the following styles for themes:
- /ui/theme-defs/<theme_name>/syntax-styles/inline-code
- /ui/theme-defs/<theme_name>/syntax-styles/type
- /ui/theme-defs/<theme_name>/syntax-styles/function
- /ui/theme-defs/<theme_name>/syntax-styles/separators-references-accessors
Multi-line block comments (i.e. /* ... */) and strings are now recognized and styled as appropriate.
Added error and data columns to the fstat() table-valued-function. The error column is non-NULL if there is a problem accessing the file. The data contains the contents of the file, as such, it is hidden by default.
Added a log format for Redis.
The :eval command will now treat its argument(s) as a script, allowing multiple commands to be executed.
Added a timezone() SQL function for converting a timestamp to a target timezone.
Added a :convert-time-to command that converts the timestamp of the focused log message to the given timezone.
Added the :set-file-timezone and :clear-file-timezone commands to set the timezone for log messages that don't include a zone in their timestamp.
Added the options_path and options columns to the lnav_file table so you can see what options are applied to a file. Currently, the only option is the default timezone that is set by the :set-file-timezone command.
Added the config file-options management command that can be used to examine the options that will be applied to a given file.
When viewing a diff, the sections of the diff for each file is recognized and shown in the breadcrumb bar. So, you can see the file the focused line is in. You can also jump to a particular file by focusing on the breadcrumb bar, selecting the crumb, and then selecting the desired file.
Binary files are now displayed as a hex dump with ASCII representation (where applicable).
Added a log_msg_line() SQL function that will return the line number of the start of the currently focused message in the log view.
Added a log_msg_values column to the all_logs SQL table that contains a JSON object with the top 5 values for the fields extracted from the log message.
Added :next-section and :prev-section commands for moving to the next and previous section of a document. For example, the next section in a man page or JSON array. The default keymap has been changed to bind the curly brace keys to these commands.
Added Nextcloud log format from Adam Monsen.
Added GitHub Event Log format for files from gharchive.org. It makes a good example of a JSON-Lines format.

Bug Fixes:

Binary data piped into stdin should now be treated the same as if it was in a file that was passed on the command-line.
The -I option is now recognized in the management CLI (i.e. when you run lnav with the -m flag).
Fields in the bro and w3c log formats that were hidden are now saved in the session and restored.
A warning will now be issued if a timestamp in a log format's sample message does not match completely. Warnings in the configuration can be viewed by passing the -W flag.
Importing from regex101.com broke due to some changes in the API.
The details overlay for a log message no longer shows keys for unknown JSON properties. These extra fields are now shown with the proper jget(log_raw_text, '/...') SQL expression needed to retrieve the value.
Improved text-wrapping when rendering Markdown.

Interface changes:

The breadcrumb bar hotkey is moving to backtick ` instead of ENTER.
The DB view now uses the "alt-text" theme style to draw alternating rows instead of being hard-coded to bold. The alternation is also now done in groups of two rows instead of only a single row. Numbers are also rendered using the "number" theme style as well.
The log message overlay in the LOG view is now limited 2/3rds of the height. You can focus on the overlay panel by pressing CTRL-]. The "alt-text" theme style is also used to draw the overlay contents now as well. (The overlay is used to display the parser details, comments, and annotations.)
The { and } keys have been changed from moving through the "location history" to moving to the previous and next section in a document.
Added indent guidelines when structured data is detected.

Breaking changes:

Removed the -w command-line option. This option was useful when stdin was not automatically preserved. Since the data is now stored (and cleaned up) as well as being spread across multiple files, this option doesn't make sense anymore.
The -t command-line flag behaves a little differently behind the scenes now. Timestamps will always be recorded for each line piped into lnav. This flag means that the data should be treated as a log file instead of plain text.
Data piped into lnav is now stored in the work directory instead of the stdin-captures dot-lnav directory.
Changed the "Bunyan" log format name from bunyan to bunyan_log to be consistent with other format names.

lnav v0.11.2

Features:

A "cursor" mode has been added to the main view that can be toggled by pressing CTRL-X. While in cursor mode, any operations that would normally work on the "top" line will now operate on the focused line instead.
Added CTRL-D and CTRL-U hotkeys to move down/up by half a page.
Added an auto-width flag to the elements of the line-format array that indicates that the width of the field should automatically be determined by the observed values.
Added bunyan log format from Tobias Gruetzmacher.
Added cloudflare log format from @minusf.
Number fields used in a JSON log format line-format array now default to being right-aligned. Also, added prefix and suffix to line-format elements so a string can optionally be prepended/appended if the value is not empty.
JSON log format detection has been improved to not rely on matching the file name. All possible formats are tried and the one with the most available fields for a given line-format is used. For example, if the first log message has 8 fields and format A contains 5 of those fields in its line-format while format B only contains 2 of those fields in its line-format, format A will be used for the file.

Changes:

For JSON-lines logs, line-feeds at the end of a value are automatically stripped.

Bug Fixes:

Hidden values in JSON logs are now hidden by default.
Text with ANSI-escapes is now filtered properly.

lnav v0.11.1

Features:

Additional validation checks for log formats have been added and will result in warnings. Pass -W on the command-line to view the warnings. The following new check have been added:
- Each regex must have a corresponding sample log message that it matches.
- Each sample must be matched by only one regex.
Added built-in support for anonymizing content. The :write-* commands now accept an --anonymize option and there is an anonymize() SQL function. The anonymization process will try to replace identifying information with random data. For example, IPv4 addresses are replaced with addresses in the 10.0.0.0/8 range. (This feature is mainly intended to help with providing information to lnav support that does not have sensitive values.)
Added parse_url() and unparse_url() SQL functions for parsing URLs into a JSON object and then back again. Note that the implementation relies on libcurl which has some limitations, like not supporting all types of schemes (e.g. mailto:).
Added the subsecond-field and subsecond-units log format properties to allow for specifying a separate field for the sub-second portion of a timestamp.
Added a keymap for Swedish keyboards.

Breaking changes:

The regexp_capture() table-valued-function now returns NULL instead of an empty string for the capture_name column if the capture is not named.

Fixes:

Reduce the "no patterns have a capture" error to a warning so that it doesn't block lnav from starting up.
Some ANSI escape sequences will now be removed before testing regexes against a log message.
If a line in a JSON-lines log file does not start with a {, it will now be shown as-is and will not have the JSON parse error.

Cost of Doing Business:

Migrated from pcre to pcre2.

lnav v0.11.0

Features:

Redesigned the top status area to allow for user-specified messages and added a second line that displays an interactive breadcrumb bar. The top status line now shows the clock and the remaining area displays whatever messages are inserted into the lnav_user_notifications table. The information that was originally on top is now in a second line and organized as breadcrumbs. Pressing ENTER will activate the breadcrumb bar and the left/right cursor keys can be used to select a particular crumb while the up/down keys can select a value to switch to. While a crumb is selected, you can also type in some text to do a fuzzy search on the possibilities or, if the crumb represents an array of values, enter the index to jump to.
The pretty-print view will now show breadcrumbs that indicate the location of the top line in the view with the prettified structure.
Markdown files (those with a .md extension) are now rendered in the TEXT view. The breadcrumb bar at the top will also be updated depending on the section of the document that you are in and you can use it to jump to different parts of the doc.
The :goto command will now accept anchor links (i.e. #section-id) as an argument when the text file being viewed has sections. You can also specify an anchor when opening a file by appending #<link-name>. For example, README.md#screenshot.
Log message comments are now treated as markdown and rendered accordingly in the overlay. Multi-line comments are now supported as well.
Metadata embedded in files can now be accessed by the lnav_file_metadata table. Currently, only the front-matter in Markdown files is supported.
Added an integration with regex101.com to make it easier to edit log message regular expressions. Using the new "management CLI" (activated by the -m option), a log format can be created from a regular expression entry on regex101.com and existing patterns can be edited.
In the spectrogram view, the selected value range is now shown by an overlay that includes a summary of the range and the number of values that fall in that range. There is also a detail panel at the bottom that shows the log-messages/DB-rows whose values are in that range. You can then press TAB to focus on the detail view and scroll around.
Add initial support for pcap(3) files using tshark(1).
SQL statement execution can now be canceled by pressing CTRL+] (same as canceling out of a prompt).
To make it possible to automate some operations, there is now an lnav_events table that is updated when internal events occur within lnav (e.g. opening a file, format is detected). You can then add SQLite TRIGGERs to this table that can perform a task by updating other tables.
Tags can automatically be added to messages by defining a pattern in a log format. Under a format definition, add the tag name into the "tags" object in a format definition. The "pattern" property specifies the regular expression to match against a line in a file that matches the format. If a match is found, the tag will be applied to the log message. To restrict matches to certain files, you can add a "paths" array whose object elements contain a "glob" property that will be matched against file names.
Log messages can now be detected automatically via "watch expressions". These are SQL expressions that are executed for each log message. If the expressions evaluates to true, an event is published to the lnav_events table that includes the message contents.
Added the regexp_capture_into_json() table-valued-function that is similar to regexp_capture(), but returns a single row with a JSON value for each match instead of a row for each capture.
Added a top_meta column to the lnav_views table that contains metadata related to the top line in the view.
Added a log_opid hidden column to all log tables that contains the "operation ID" as specified in the log format.
Moved the log_format column from the all_logs table to a hidden column on all tables.
Add format for UniFi gateway.
Added a glob property to search tables defined in log formats to constrain searches to log messages from files that have a matching log_path value.
Initial indexing of large files should be faster. Decompression and searching for line-endings are now pipelined, so they happen in a thread that is separate from the regular expression matcher.
Writing to the clipboard now falls back to OSC 52 escape sequence if none of the clipboard commands could be detected. Your terminal software will need to support the sequence and you may need to explicitly enable it in the terminal.
Added the :export-session-to <path> command that writes the current session state to a file as a list of commands/SQL statements. This script file can be executed to restore the majority of the current state.
Added the echoln() SQL function that behaves similarly to the :echo command, writing its first argument to the current output.
Added encode() and decode() SQL functions for transcoding blobs or text values using one of the following algorithms: base64, hex, or uri.
In regular expressions, capture group names are now semantically highlighted (e.g. in the capture, (?<name>\w+), "name" would have a unique color). Also, operations or previews that use that regular expression will highlight the matched data with the same color.
Added an lnav_views_echo table that is a real SQLite table that you can create TRIGGERs on in order to perform actions when scrolling in a view.
Added a yaml_to_json() SQL function that converts a YAML document to the equivalent JSON.

Breaking Changes:

Formats definitions are now checked to ensure that values have a corresponding capture in at least one pattern.
Added a 'language' column to the lnav_view_filters table that specifies the language of the 'pattern' column, either 'regex' or 'sql'.
Timestamps that do not have a day or month are rewritten to a full timestamp like YYYY-MM-DD HH:MM:SS.
Removed the summary overlay at the bottom of the log view that displayed things like "Error rate" and the time span. It doesn't seem like anyone used it.
Removed the log_msg_instance column from the logline and search tables since it causes problems with performance.
Search tables now search for multiple matches within a message instead of stopping at the first hit. Each additional match is returned as a separate row. A match_index column has been added to capture the index of the match within the message. The table regex is also compiled with the "multiline" flag enabled so the meaning of the ^ and $ metacharacters are changed to match the start/end of a line instead of the start/end of the entire message string.
Search tables defined in formats are now constrained to only match log messages that are in that log format instead of all log messages. As a benefit, the search table now includes the columns that are defined as part of the format.
The lnav_view_filters table will treats the tuple of (view_name, type, language, pattern) as a UNIQUE index and will raise a conflict error on an INSERT. Use REPLACE INTO instead of INSERT INTO to ignore conflict error.
The types of SQL values stored as local variables in scripts is now preserved when used as bound variables at a later point in the script.

Fixes:

Toggling enabled/disabled filters when there is a SQL expression no longer causes a crash.
Fix a crash related to long lines that are word wrapped.
Multiple SQL statements in a SQL block of a script are now executed instead of just the first one.
In cases where there were many colors on screen, some text would be colored incorrectly.
The pretty-print view now handles ANSI escape sequences.
The "overstrike" convention for doing bold and underline is now supported. (Overstrike is a character followed by a backspace and then the same character for bold or an underscore for underline.)
The :eval command now works with searching (using the '/' prefix).

lnav v0.10.1

Features:

Added :show-only-this-file command that hides all files except the one for the top line in the view.
The :write-raw-to command now accepts a --view flag that specifies the source view for the data to write. For example, to write the results of a SQL query, you would pass --view=db to the command.
The commands used to access the clipboard are now configured through the "tuning" section of the configuration.
Added an lnav_version() SQL function that returns the current version string.
Added basic support for the logfmt file format. Currently, only files whose lines are entirely logfmt-encoded are supported. The lines must also contain either a field named time or ts that contains the timestamp.
Added the logfmt2json() SQL function to convert a string containing a logfmt-encoded message into a JSON object that can be operated on more easily.
Added the gzip() and gunzip() SQL functions to compress values into a blob and decompress a blob into a string. Interface changes:
The xclip implementation for accessing the system clipboard now writes to the "clipboard" selection instead of the "primary" selection.
The 'query' bookmark type and y/Y hotkeys have been removed due to performance issues and the functionality is probably rarely used. Bug Fixes:
The text "send-input" would show up on some terminals instead of ignoring the escape sequence. This control sequence was only intended to be used in the test suite.
Remote file synchronization has been optimized a bit.
Configuration values loaded from the ~/.lnav/configs directory are now included in the default configuration, so they won't be saved into the ~/.lnav/config.json user configuration file.
Key handling in the visual filter editor will no longer swallow certain key-presses when editing a filter.
Scrolling performance restored in the SQL view.
The :redirect-to command now works with /dev/clipboard
The field overlay (opened by pressing 'p') now shows log_time for the timestamp field instead of the name defined in the format.
The search term in the bottom status bar will now update properly when switching views.
The "Out-Of-Time-Order Message" overlay will be shown again.
The tab for the "Files" panel will be highlighted in red if there is an issue opening a file.
Overwritten files should be reloaded again.
The jget() SQL function now returns numbers with the correct type.
The json_contains() SQL function now returns false if the first argument is NULL instead of NULL.
The local copies of remote files are now cleaned up after a couple days of the host not being accessed.
The initial loading and indexing phase has been optimized.

lnav v0.10.0

Features:

Files on remote machines can be viewed/tailed if they are accessible via SSH. The syntax for specifying the host and path is similar to scp. For example, to view the files in the /var/log directory on the machine host1.example.org:
```
$ lnav user@host1.example.org:/var/log
```
Note that you must be able to log into the machine without any interaction.
Added the :filter-expr command to filter log messages based on an SQL expression. This command allows much greater control over filtering.
Added the :mark-expr command to mark log messages based on an SQL expression. This command makes it easier to programmatically mark log messages compared to using SQL.
Added support for archive files, like zip, and other compression formats, like xz, when compiled with libarchive. When one of these types of files is detected, they are unpacked into a temporary directory and all the files are loaded into lnav.
Added an xpath() table-valued function for extracting values from strings containing XML snippets.
Added the :prompt command to allow for more customization of prompts. Combined with a custom keymapping, you can now open a prompt and prefill it with a given value. For example, a key could be bound to the following command to open the command prompt with :filter-in already filled in:
```
:prompt command : 'filter-in '
```
Added support for the W3C Extended Log File Format with the name w3c_log. Similarly to the bro log format, the header is used to determine the columns in a particular file. However, since the columns can be different between files, the SQL table only has a well-known set of columns and the remainder are accessible through JSON-objects stored in columns like cs_headers and sc_headers.
Added support for the S3 Access File Format.
To jump to the first search hit above the top line in a view, you can press CTRL+J instead of ENTER in the search prompt. Pressing ENTER will jump to the first hit below the current window.
Filtering, as a whole, can be now disabled/enabled without affecting the state of individual filters. This includes text and time-filters (i.e. :hide-lines-before). You can enable/disable filtering by: pressing f in the filter editor UI; executing the :toggle-filtering command; or by doing an UPDATE on the "filtering" column of the lnav_views SQLite table.
Themes can now include definitions for text highlights under: /ui/theme-defs/<theme_name>/highlights
Added a "grayscale" theme that isn't so colorful.
Added the humanize_file_size() SQL function that converts a numeric size to a human-friendly string.
Added the sparkline() SQL function that returns a "sparkline" bar made out of unicode characters. It can be used with a single value or as an aggregator.
Added a log_time_msecs hidden column to the log tables that returns the timestamp as the number of milliseconds from the epoch.
Added an lnav_top_file() SQL function that can be used to get the name of the top line in the top view or NULL if the line did not come from a file.
Added a mimetype column to the lnav_file table that returns a guess as to the MIME type of the file contents.
Added a content hidden column to the lnav_file table that can be used to read the contents of the file. The contents can then be passed to functions that operate on XML/JSON data, like xpath() or json_tree().
Added an lnav_top_view SQL VIEW that returns the row for the top view in the lnav_views table.
The generate_series() SQLite extension is now included by default. One change from the standard implementation is that both the start and stop are required parameters.
Added the ;.read SQL command for executing a plain SQL file.
Added the -N flag so that lnav will run without opening the default syslog file.

Interface Changes:

When copying log lines, the file name and time offset will be included in the copy if they are enabled.
Log messages that cannot be parsed properly will be given an "invalid" log level and the invalid portions colored yellow.
The range_start and range_stop values of the regexp_capture() results now start at 1 instead of zero to match with what the other SQL string functions expect.
The :write-cols-to command has been renamed to :write-table-to.
The DB view will limit the maximum column width to 120 characters.
The :echo command now evaluates its message to do variable substitution.
The :write-raw-to command has been changed to write the original log file content of marked lines. For example, when viewing a JSON log, the JSON-Line values from the log file will be written to the output file. The :write-view-to command has been added to perform the previous work of :write-raw-to where the raw content of the view is written to the file.

Fixes:

Unicode text can now be entered in prompts.
The replicate() SQL function would cause a crash if the number of replications was zero.
Many internal improvements.

lnav v0.9.0

Features:

Added support for themes and included a few as well: default, eldar, monocai, night-owl, solarized-light, and solarized-dark. The theme can be changed using the :config command, like so:
```
:config /ui/theme night-owl
```
Consult the online documentation for defining a new theme at: https://lnav.readthedocs.io/en/latest/config.html#theme-definitions
Added support for custom keymaps and included the following: de, fr, uk, us. The keymap can be changed using the :config command, like so:
```
:config /ui/keymap uk
```
Consult the online documentation for defining a new keymap at: https://lnav.readthedocs.io/en/latest/config.html#keymap-definitions
The following JSON-Schemas have been published for the log format and configuration JSON files:
- https://lnav.org/schemas/format-v1.schema.json
- https://lnav.org/schemas/config-v1.schema.json
Formats should be updated to reference the schema using the $schema property.
Indexing of new data in log files can now be paused by pressing = and unpaused by pressing it again. The bottom status bar will display 'Paused' in the right corner while paused.
CMake is now a supported way to build.
When viewing data from the standard-input, a symbolic name can be used to preserve session state. The name can be changed using the |rename-stdin lnav script or by doing an UPDATE to the filepath column of the lnav_file table. For example, to assign the name "journald", the following SQL statement can be executed in lnav:
```
;UPDATE lnav_file SET filepath='journald' WHERE filepath='stdin'
```
The size of the terminal can be accessed in SQL using the $LINES and $COLS variables.
The raise_error(msg) SQL function has been added to make it easier to raise an error in an lnav script to stop execution and notify the user.
Added the json_concat() function to make it easier to append/concatenate values onto arrays.
Added the :write-jsonlines-to command that writes the result of a SQL query to a file in the JSON Lines format.

Interface Changes:

Data piped into lnav is no longer dumped to the console after exit. Instead, a file containing the data is left in .lnav/stdin-captures/ and a message is printed to the console indicating the file name.
In time-offset mode, the deltas for messages before the first mark are now negative instead of relative to the start of the log.
The $XDG_CONFIG_HOME environment variable (or ~/.config directory) are now respected for storing lnav's configuration. If you have an existing ~/.lnav directory, that will continue to be used until you move it to $XDG_CONFIG_HOME/lnav or ~/.config/lnav.
Removed the :save-config command. Changes to the configuration are now immediately saved.

Fixes:

Added 'notice' log level.
If a timestamp-format is used in an element of a line-format, the field name is ignored and a formatted timestamp is always used.
Ignore stdin when it is connected to /dev/null.

lnav v0.8.5

Features:

Added a visual filter editor to make it easier to update existing filters. The editor can be opened by pressing TAB. Once the editor is opened, you can create/delete, enable/disable, and edit the patterns with hotkeys.
Added an lnav_view_filters SQL table that can be used to programmatically manipulate filters.
Added an lnav_view_filter_stats SQL table that contains the number of times a given filter matched a line in the view.
Added a log_filters column to log tables that can be used to see what filters matched the log message.
A history of locations in a view is now kept so that you can jump back to where you were previously using the { and } keys. The location history can also be accessed through the :prev-location and :next-location commands.
The :write-* commands will now accept /dev/clipboard as a file name that writes to the system clipboard.
The :write-to and :write-raw-to commands will now print out comments and tags attached to the lines.
Added a :redirect-to <path> command to redirect command output to the given file. This command is mostly useful in scripts where one might want to redirect all output from commands like :echo and :write-to - to a single file.
If a log file format has multiple patterns for matching log messages, each pattern is now tried to match a message in a file. Previously, only one pattern was ever used for an entire file.
Added haproxy log format from Peter Hoffmann.
Added spooky_hash() and group_spooky_hash() SQL functions to generate a hash of their parameters.
Added time_offset to the lnav_file table so that the timestamps in a file can be adjusted programmatically.

Interface Changes:

The auto-complete behavior in the prompt has been modified to fall back to a fuzzy search if the prefix search finds no matches. For example, typing in :fin and pressing TAB would previously not do anything. Now, the :fin will be completed to :filter-in since that is a strong fuzzy match. If there are multiple matches, as would happen with :dfil, readline's menu-complete behavior will be engaged and you can press TAB cycle through the options.
Added CTRL+F to toggle the enabled/disabled state of all filters for the current view.
The -r flag is now for recursively loading files. The functionality for loading rotated files is now under the -R flag.
The current search term is now shown in the bottom status bar.
Some initial help text is now shown for the search and SQL prompts to refresh the memory.
When entering the :comment command for a line with a comment, the command prompt will be filled in with the existing comment to make editing easier.
Hidden fields now show up as a unicode vertical ellipsis (⋮) instead of three-dot ellipsis to save space.
Pressing 7/8 will now move to the previous/next minute.
The :write-raw-to command has been changed to write the entire contents of the current view and a :write-screen-to command has been added to write only the current screen contents.
Disabled filters are now saved in sessions.
The :adjust-log-time command now accepts relative times as input.

Fixes:

The :write-json-to command will now pass through JSON cells as their JSON values instead of a JSON-encoded string.

lnav v0.8.4

Features:

Added the :comment command that can be used to attach a comment to a log line. The comment will be displayed below the line, like so:
```
2017-01-01T15:30:00 error: computer is on fire
  + This is where it all went wrong
```
The :clear-comment command will remove the attached comment. Comments are searchable with the standard search mechanism and they are available in SQL through the log_comment column.
Added the :tag, :untag, and :delete-tags commands that can be used to attach/detach tags on the top log line and delete all instances of a tag. Tags are also searchable and are available in SQL as a JSON array in the log_tags column.
Pressing left-arrow while viewing log messages will reveal the source file name for each line and the unique parts of the source path. Pressing again will reveal the full path.
The file name section of the top status line will show only the unique parts of the log file path if there is not enough room to show the full path.
Added the :hide-unmarked-lines and :show-unmarked-lines commands that hide/show lines based on whether they are bookmarked.
Added the json_contains() SQL function to check if a JSON value contains a number of a string.
The relative time parser recognizes "next" at the beginning of the input, for example, "next hour" or "next day". Handy for use in the :goto command.
Added a "text-transform" option for formatting JSON log messages. The supported options are: none, uppercase, lowercase, and capitalize.
Added a special __level__ field name for formatting JSON messages so that the lnav level name can be used instead of the internal value in the JSON object.
Added a log format for journald JSON logs.

Interface Changes:

When typing in a search, instead of moving the view to the first match that was found, the first ten matches will be displayed in the preview window.
The pretty-print view maintains highlighting from the log view.
The pretty-print view no longer tries to reverse lookup IP addresses.
The online help for commands and SQL functions now includes a 'See Also' section that lists related commands/functions.

Fixes:

The HOME key should now work in the command-prompt and move the cursor to the beginning of the line.
The :delete-filter command should now tab-complete existing filters.
Milliseconds can now be used in relative times (e.g. 10:00:00.123)
The J/K hotkeys were not marking lines correctly when the bottom of the view was reached.
The level field in JSON logs should now be recognized by the level patterns in the format.

lnav v0.8.3

Features:

Support for the Bro Network Security Monitor (https://www.bro.org) log file format.
Added an fstat() table-valued function for querying the local filesystem.
Added readlink() and realpath() SQL functions.
Highlights specified in log formats can now specify the colors to use for the highlighted parts of the log message.
Added a :quit command.
Added a /ui/default-colors configuration option to specify that the terminal's default background and foreground colors should be used instead of black and white.

Interface Changes:

Pressing delete at a command-prompt will exit the prompt if there is no other input.

Fixes:

The help view now includes all the command-help that would pop up as you entered commands and SQL queries.
Hidden fields and lines hidden before/after times are now saved in the current session and restored.
Unicode characters should now be displayed correctly (make sure you have LANG set to a UTF-8 locale).

lnav v0.8.2

Features:

The timestamp format for JSON log files can be specified with the timestamp-format option in the line-format array.
Added "min-width", "max-width", "align", and "overflow" options to the "line-format" in format definitions for JSON log files. These options give you more control over how the displayed line looks.
Added a "hidden" option to log format values so that you can hide JSON log fields from being displayed if they are not in the line format.
Added a rewriter field to log format value definitions that is a command used to rewrite the field in the pretty-printed version of a log message. For example, the HTTP access log format will rewrite the status code field to include the textual version (e.g. 200 (OK)).
Log message fields can now be hidden using the :hide-fields command or by setting the 'hidden' property in the log format. When hidden, the fields will be replaced with a yellow ellipsis when displayed. Hiding large fields that contain extra details can make the log easier to read. The x hotkey can be used to quickly toggle whether these fields are displayed or not.
Added a :mark command to bookmark the top line in the current view.
Added an :alt-msg command that can be used to set the text to be displayed in the bottom right of the command line. This command is mostly intended for use by hotkey maps to set the help text.
In lnav scripts, the first row of a SQL query result will now be turned into local variables that can be referenced in other commands or queries. For example, the following script will print the number one:
```
;SELECT 1 as foobar
:eval :echo ${foobar}
```
Added an lnav_view_stack SQL table that gives access to the view stack.
Added a top_time column to the lnav_views table so that you can get the timestamp for the top line in views that are time-based as well as allowing you to move the view to a given time with an UPDATE statement.
Added a 'search' column to the lnav_views table so that you can perform a text search programmatically.
Added a regexp_capture(<string>, <pattern>) table-valued function for getting detailed results from matching a regular expression against a string.
Added a timediff(<time1>, <time2>) SQL function for computing the difference between two relative or absolute timestamps.
Log formats can now define a default set of highlights with the "highlights" property.
Added a |search-for <pattern> built-in script that can be used to start a search from the command-line.
Log format definitions can now specify the expected log level for a sample line. This check should make it easier to validate the definition.

Interface Changes:

Command and SQL documentation is now displayed in a section at the bottom of the screen when a command or query is being entered. Some commands will also display a preview of the command results. For example, the :open command will display the first ten lines of the file to be opened and the :filter-out command will highlight text that matches in the current view. The preview pane can be shown/hidden by pressing CTRL-P.
The color used for text colored via :highlight is now based on the the regex instead of randomly picked so that colors are consistent across invocations.
The "graph" view has been removed since it's functionality has been obsoleted by other features, like :create-search-table.
When doing a search, if a hit is found within a second after hitting <ENTER>, the view will move to the matched line. The previous behavior was to stay on the current line, which tended to be a surprise to new users.
Pressing n/N to move through the next/previous search hit will now skip adjacent lines, up to the vertical size of the view. This should make scanning through clusters of hits much faster. Repeatedly pressing these keys within a short time will also accelerate scanning by moving the view at least a full page at a time.

Breaking Changes:

The captured timestamp text in log files must fully match a known format or an error will be reported. The previous behavior was to ignore any text at the end of the line.

Fixes:

You can now execute commands from the standard input by using a dash (-) with the -f command-line argument. Reading commands from a file descriptor should also work, for example, with the following bash syntax:
```
$ lnav -f <(echo :open the-file-to-open)
```
Programming language syntax highlighting should now only be applied to source code files instead of everywhere.

lnav v0.8.1

Features:

Added a spectrogram command and view that displays the values of a numeric field over time. The view works for log message fields or for database result columns.
Log formats can now create SQL views and execute other statements by adding .sql files to their format directories. The SQL scripts will be executed on startup.
Added json_group_object and json_group_array aggregate SQL functions that collects values from a GROUP BY query into a JSON object or array, respectively.
The SQL view will now graph values found in JSON objects/arrays in addition to the regular columns in the result.
Added an regexp_match(<re>, <str>) SQL function that can be used to extract values from a string using a regular expression.
Added an extract(<str>) SQL function that extracts values using the same data discover/extraction parser used in the logline table.
Added a "summary" overlay line to the bottom of the log view that displays how long ago the last message was received, along with the total number of files and the error rate over the past five minutes.
Pressing V in the DB view will now check for a column with a timestamp and move to the corresponding time in the log view.
Added a/A hotkeys to restore a view previously popped with q/Q.
Added :hide-lines-before, :hide-lines-after, and :show-lines-before-and-after commands so that you can filter out log lines based on time.
Scripts containing lnav commands/queries can now be executed using the pipe (|) hotkey. See the documentation for more information.
Added an :eval command that can be used to execute a command or query after performing environment variable substitution.
Added an :echo command that can be useful for scripts to message the user.
The log_part column can now be set with an SQL UPDATE statement.
Added a log_body hidden column that returns the body of the log message.
Added :config, :reset-config, and :save-config commands to change configuration options, reset to default, and save them for future executions.
Added a /ui/clock-format configuration option that controls the time format in the top-left corner.
Added a /ui/dim-text configuration option that controls the brightness of text in the UI.
Added support for TAI64 timestamps (http://cr.yp.to/libtai/tai64.html).
Added a safe execution mode. If the LNAVSECURE environment variable is set before executing lnav, the following commands are disabled:
- :open
- :pipe-to
- :pipe-line-to
- :write-*-to
This makes it easier to run lnav with escalated privileges in restricted environments, without the risk of users being able to use the above mentioned commands to gain privileged access.

Interface Changes:

The o/O hotkeys have been reassigned to navigate through log messages that have a matching "opid" field. The old action of moving forward and backward by 60 minutes can be simulated by using the :goto command with a relative time and the r/R hotkeys.
Log messages with timestamps that pre-date previous log messages will have the timestamp highlighted in yellow and underlined. These out- of-time-order messages will be assigned the time of the previous message for sorting purposes. You can press the 'p' hotkey to examine the 'Received Time' of the message as well as the time parsed from the original message. A log_actual_time hidden field has also been added to the SQLite virtual table so you can operate on the original message time from the file.
The A/B hotkeys for moving forward/backward by 10% line increments have been reassigned to [ and ]. The a and A hotkeys are now used to return to the previously popped view while trying to preserve the time range. For example, after leaving the spectrogram view with 'q', you can press 'A' return to the view with the top time in the spectrogram matching the top time in the log view.
The 'Q' hotkey now pops the current view off of the stack while maintaining the top time between views.

Fixes:

Issues with tailing JSON logs have been fixed.
The jget() SQL function should now work for objects nested in arrays.

lnav v0.8.0

Features:

Integration with "papertrailapp.com" for querying and tailing server log and syslog messages. See the Papertrail section in the online help for more details.
Remote files can be opened when lnav is built with libcurl v7.23.0+
SQL queries can now be done on lines that match a regular expression using the log_search table or by creating custom tables with the :create-search-table command.
Log formats that are "containers" for other log formats, like syslog, are now supported. See the online help for more information.
Formats can be installed from git repositories using the -i option. A standard set of extra formats can be installed by doing lnav -i extra. (You must have git installed for this to work.)
Added support for 'VMware vSphere Auto Deploy' log format.
Added a 'sudo' log format.
Added hotkeys to move left/right by a smaller increment (H/L or Shift+Left/Shift+Right).
A color-coded bar has been added to the left side to show where messages from one file stop and messages from another file start.
The -C option will now try to check any specified log files to make sure the format(s) match all of the lines.
Added an all_logs SQLite table that contains the message format extracted from each log line. Also added a ;.msgformat SQL command that executes a query that returns the counts for each format and the first line where the format was seen.
Added an lnav_views SQLite table that can be used to query and change the lnav view state.
When typing in a command, the status bar will display a short summary of the currently entered command.
Added a :delete-filter command.
Added a log_msg_instance column to the logline and log_search tables to make it easier to join tables that are matching log messages that are ordered.
Added a timeslice() function to SQLite so that it is easier to group log messages by time buckets.
The :goto command now supports relative time values like a minute ago, an hour later, and many more.

Interface Changes:

The r/R hotkeys have been reassigned to navigate through the log messages by the relative time value that was last used with the :goto command.

Fixes:

The pretty-print view should now work for text files.
Nested fields in JSON logs are now supported for levels, bodies, etc...
Tab-completion should work for quoted SQL identifiers.
'lo-fi' mode key shortcut changed to CTRL+L.
'redraw' shortcut removed. Relegated to just a command.
Fixed lnav hang in pretty-print mode while doing a dns lookup.
The generic log message parser used to extract data has been optimized and should be a bit faster.

lnav v0.7.3

Features:

Add :pipe-to and :pipe-line-to commands that pipe the currently marked lines or the current log message to a shell command, respectively.
Added a "pretty-print" view (P hotkey) that tries to reformat log messages so that they are easier to read.
Added a :redraw command (CTRL+L hotkey) to redraw the window in case it has been corrupted.
Added a :relative-goto command to move the current view relative to its current position.
Experimental support for linking with jemalloc.
The plain text view now supports filtering.
Added :next-mark and :prev-mark commands to jump to the next or previous bookmarked line (e.g. error, warning, ...)
Added a :zoom-to command to change the zoom level of the histogram view.
Log formats can now define their own timestamp formats with the timestamp-format field.

Fixes:

Autotools scripts overhaul.
Added a configure option to disable linking with libtinfo. The newer versions of ncurses don't require it, however the build silently pulls it in as a dependency, if it is available on the system. This can be explicitly disabled using the --disable-tinfo option during configure.
Fixed the configure script behavior to ignore the values specified using the CFLAGS and LDFLAGS environment variables while searching for sqlite3 when --with-sqlite3 switch was specified without the prefix.
The configure script now recognizes libeditline symlink'ed to masquerade as libreadline. This previously used to cause problems at compile time, specially on OS X. If you come across this error, use the --with-readline=prefix switch to specify the path to the correct location of libreadline.
The order that log formats are tried against a log file is now automatically determined so that more specific formats are tested before more general ones. The order is determined on startup based on how each format matches each other formats sample lines.
Command files (i.e. those executed via the -f flag) now support commands/queries that span more than one line.
Added more log levels: stats, debug2 - debug5.

lnav v0.7.2

Added log formats for vdsm, openstack, and the vmkernel.
Added a "lo-fi" mode (L hotkey) that dumps the displayed log lines to the terminal without any decorations. The :write-to, :write-json-to, and :write-csv-to commands will also write their output to the terminal when passed - as the file name. This mode can be useful for copying plain text lines to the clipboard.
(OS X) Text search strings are copied to the system's "find" clipboard. Also, when starting a new search, the current value in the "find" clipboard can be tab-completed.

lnav v0.7.1

Features:

Added an environ SQL table that reflects lnav's environment variables. The table can be read and written to using SQL SELECT, INSERT, UPDATE, and DELETE statements. Setting variables can be a way to use SQL query results in lnav commands.
Added a jget() SQLite function that can extract fields from a JSON- encoded value.
Added log formats for the OpenAM identity provider.
Added a :clear-highlight command to clear previous calls to the :highlight command.
Fixed some performance bugs in indexing JSON log formats. Loading times should be at least five times faster.
Filtering performance should be improved so that enabling/disabling filters should be almost instantaneous.
The :filter-in, :filter-out, and :highlight commands now support tab-completion of text in the current view.
Add a -i flag that installs format files in: ~/.lnav/formats/installed

lnav v0.7.0

Features:

Add the '.schema' SQL command to open a view that displays the schema for the internal tables and any attached databases. If lnav was only executed with a SQLite database and no text files, this view will open by default.
The scroll bar now indicates the location of errors/warnings, search hits, and bookmarks.
The xterm title is update to reflect the file name for the top line in the view.
Added a "headless" mode so that you can execute commands and run SQL queries from the command-line without having to do it from the curses UI.
When doing a search or SQL query, any text that is currently being displayed can be tab-completed.
The -H option was added so you can view the internal help text.
Added the 'g/G' hotkeys to move to the top/bottom of the file.
Added a log_mark column to the log tables that indicates whether or not a log message is bookmarked. The field is writable, so you can bookmark lines using an SQL UPDATE query.
Added syntax-highlighting when editing SQL queries or search regexes.
Added a :write-json-to command that writes the result of a SQL query to a JSON-formatted file.
The "elapsed time" column now uses red/green coloring to indicate sharp changes in the message rate.
Added a :set-min-log-level command to filter out log messages that are below a given level.

Fixes:

Performance improvements.
Multi-line filtering has been fixed.
A collator has been added to the log_level column in the log tables so that you can write expressions like log_level > 'warning'.
The log_time datetime format now matches what is returned by datetime('now') so that collating works correctly.
If a search string is not valid PCRE syntax, a search is done for the exact string instead of just returning an error.
Static-linking has been cleaned up.
OpenSSL is no longer a requirement.
Alpha support for Windows/cygwin.
Environment variables can now be accessed in SQL queries using the syntax: $VAR_NAME
An internal log is kept and written out on a crash.
Partition bookmarks are now tracked separately from regular user bookmarks. You can start a partition with the 'partition-name' command and remove it with the 'clear-partition' command.
Improved display of possible matches during tab-completion in the command-prompt. The matches are now shown in a separate view and pressing tab repeatedly will scroll through the view.
The "open" command now does shell word expansion for file names.
More config directory paths have been added: /etc/lnav, $prefix/etc/lnav, and directories passed on the command-line with -I.

lnav v0.6.2

Features:

Word-wrap support.

Fixes:

Fix some OS X Mavericks build/runtime issues.

Support for JSON-encoded log files.

Fixes:

Some minor fixes and performance improvements.

lnav v0.6.0

Features:

Custom log formats and more builtin formats

UI improvements, support for 256 color terminals

lnav v0.5.1

Features:

Added the -t and -w options which can be used to prepend a timestamp to any data piped in on stdin and to specify a file to write the contents of stdin to.

Fixes:

Cleanup for packaging.

lnav v0.5.0

Features:

Files can be specified on the command-line using wildcards so that new files are automatically loaded. Directories can also be passed as command-line arguments to read all of the files in the directory.
Builds on cygwin again.
Added the C hotkey to clear any existing user bookmarks.
Added experimental support for accepting input from mice.

Fixes:

Internal cleanup.
Copying to the clipboard on OS X is now supported.
Many bug fixes.

lnav v0.4.0

Features:

Files that are not recognized as containing log messages have been broken out to a separate text files view. You can flip between the log view and the text file view with the t hotkey. When viewing text files, the f hotkey will switch between files.
Files compressed with bzip2 are recognized and decompressed on the fly.
Added a "session" file and command for storing commands that should be executed on startup. For example, if you always want some highlighting to be done, you can add that command to the session file.

Fixes:

Add some more log file formats for generic log files.
Performance improvements for compressed files.
Works on OS X now.

lnav v0.3.0

Changes:

The hotkey for the SQL view was changed to v and V from '.'.

Features:

You can now switch between the SQL result view and the log view while keeping the top of the views in sync with the log_line column.

Fixes:

The log_line column is no longer included in the SQL result view's stacked bar graph.
Added a "warnings" count to the histogram view.
