Auto Update LSP on Startup seems to be ignored.

[crashmeister]

When I start Netbeans (v19) and open a python source file, the configuration I have set up is not implemented.
I have to open settings, add a space to the config somewhere to trick it into thinking it has been updated, the click 'Apply'.
At this point my config works. Opening another files shows correct implementation of the config. When I quit Netbeans, the config is lost.

I should NOT have to do this every time I open Netbeans. My config should be applied automatically.

This shows all the code marked with violations after opening Netbeans:

This shows the LSP Server tab in Netbeans Settings, Auto Update is checked:

This shows the same code correctly displayed after applying a dummy 'space' change to the config:

Thanks.
Craig.

Thanks for reporting this issue, we will take a look on ASAP

@crashmeister Make sure your configuration is correct. From the screenshot i can already tell it is not: maxLineLenght must be number not string.
Make sure the config follow https://github.com/python-lsp/python-lsp-server?tab=readme-ov-file#configuration

If its still not working. Provide Log from: View -> Python LSP log

[crashmeister]

1. There is no 'Python LSP log' in the 'View' menu.
2. I fixed the numeric literal and checked for others. The issue remained after correction.
3. After starting the IDE, under the 'Output' area, the 'Creating pylsp environment' tab is empty.
4. Under the 'Output' area, the 'Installing pylsp dependencies' tab contains data. See attached text file.

The file /Users/Craig/Library/Application Support/NetBeans/19/.pythonlsp/lsp_log_file is empty.

If the 'Python LSP Log' you referenced is available elsewhere in the file system, let me know where so I can find it.

If the config was the issue, the issue would NOT have corrected itself after adding/removing a space to the config.

1. There is no 'Python LSP log' in the 'View' menu.

If there is none thats mean you are not using the latest version. Upgrade to 1.8!

I just tested the feature and it is working:

1. Default configuration:
   pycodestyle.maxLineLength = 80 => Warning in Editor: E501 line too long (86 > 80 characters)

2. Update pycodestyle.maxLineLength = 75 and restart => Warning in Editor: E501 line too long (86 > 75 characters)

If its not working on your side thats probably means your config is rejected by the LSP server (due to some incoherence or else) and you should get a trace in the log file

This issue contains informations that might help you: #92

[crashmeister]

Please note that I am using MacOS, not Windows.

Upgraded to 1.8. Copied your config above. Removed the ** from line length.
The log file is now present under 'View', but nothing ever appears inside it.
I made some deliberate syntax errors in the config and it now sometimes displays an error message under the config window. Other errors (eg: JSON Syntax) seem to appear in the IDE log.

I tried a few changes to the config but cannot get it do what I want. Example:

I changed the ignore to:
"ignore": ["E114","E221","E271","E272"],
but those rule violations are still flagged.

All I want is to have syntax highlighting and basic syntax checking (NOT coding rules). Is this possible ?

[crashmeister]

Found this in the IDE.log while playing with the config settings, may be why no log entries:

SLF4J: No SLF4J providers were found.
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See https://www.slf4j.org/codes.html#noProviders for further details.

@crashmeister : your problem is that your are using an empty config: "" to flake8 which override everything.

This config works well for me:

"flake8": {
            "enabled": true,
            "exclude": [],
            "executable": "flake8",
            "filename": "",
            "hangClosing": false,
            "ignore": ["E501"],
            "maxLineLength": 75,
            "indentSize": 4,
            "perFileIgnores": []
        }, 

you need to remove:

"config": "",
"select": [
                ""
            ]

I made a little fix so that the log is more verbose. Upgrade to version 1.9

[crashmeister]

Wow, not sure what is going on here.

1. I installed 1.9 into NB-20.
2. Removed lines as suggested.
3. Got these:

[albilu]

Ok this wasnt expected.
Quick workaround: copy https://github.com/albilu/netbeansPython/blob/master/src/main/resources/org/netbeans/modules/python/schema.json to your /Users/Craig/Library/Application Support/NetBeans/20/.pythonlsp/schema.json

[crashmeister]

BTW, the LSP log is now populated. Thanks.

[crashmeister]

Status update:

Copied the schema.
Changed using flake8 to pycodestyle.
Added a whole bunch to the ignore list.

For the first time, the code checking is now working, which is great.

Unfortunately, it is still loading the wrong config on startup. I still have to force a reload in settings to get the right one loaded.

1. On NB startup with no open python files, there is no LSP log yet, but there is the 'Installing pylsp dependencies' output. I have attached the output.
2. I then open a python file, and some (default?) configuration is active. See the LSP log attached (first part). Note line length and indentation violations (as opposed to my config below).
3. I then open settings and my own config is present in the config window. I add a space and 'Apply' it.
4. At this point my configuration is active and the results are as I would expect. See the attached LSP Log (second part). Note absence of ignored violations.

My config sets pycodestyle as follows:

        "pycodestyle": {
            "comment":                    "Linter for style checking",
            "enabled":                    true,
            "exclude":                    [],
            "filename":                   [],
            "ignore":                     ["E114","E117","E121","E124","E126","E127","E128","E131"
                                          ,"E201","E203","E221","E222","E241","E251","E271"
                                          ,"E272","E303","E501","W504"],
            "hangClosing":                false,
            "maxLineLength":              120,
            "indentSize":                 2
        },
