html-to-text-cli

@html-to/text-cli

Command line interface for html-to-text Node.js package.

Features

• almost all html-to-text options can be specified via command line arguments or json config (the only exception is functions such as custom formatters);
• a couple of presets for common use cases (human reading in terminal and machine indexing/search).

Changelog

Available here: CHANGELOG.md

Installation

npm i -g @html-to/text-cli

Name collisions

• old versions of html-to-text package expose a command with the same name. Make sure that package is not installed globally anymore.
• there is an old abandoned CLI package that exposes a command with the same name and actually has nothing to do with html-to-text package. Make sure to only use namespaced package @html-to/text-cli.

Usage

• Use html-to-text command (html-to-text.cmd in PowerShell);
• Pipe HTML to stdin;
• Get plain text from stdout;
• Pass converter options as command arguments.

Command line arguments

> cat ./input.html | html-to-text [commands...] [keys and values...] > ./output.txt

In PowerShell:

PS> Get-Content .\input.html | html-to-text.cmd [commands...] [keys and values...] > .\output.txt

.ps1 wrapper installed by npm might not work with stdin, so use .cmd instead.

Available commands

Command	Alias	Argument	Description
json	-j	<file_name>	Merge given json file contents with the parsed options object. This way you can provide all or some options from a file rather than explicitly from CLI.
preset	-p	<preset_name>	Merge given preset into the parsed options object. Available presets listed below.
inspect	-i		Pretty print the parsed options object and exit. Useful as a dry run to check how options are parsed.
unparse	-u		Print the parsed options object back as args string and exit. Can be used to check what arguments produce the result equivalent to a given json file.
help	-h		Print help message end exit.
version	-v		Print version number and exit.

Note: short aliases cannot be merged.

Available presets

Preset	Description
human	Some options more suitable for human reading in terminal (ensure line length of 80 characters, format tables visually)
machine	Some options more suitable for machine processing (no line length limit, format tables and cells as blocks)

Options syntax

Refer to html-to-text help output for brief syntax information.

Refer to aspargvs readme for more detailed information.

Note: PowerShell requires to escape quotes and curly braces.

Option examples

{ wordwrap: 100 }	--wordwrap=100
{ wordwrap: false }	--!wordwrap
{ baseElements: { orderBy: 'occurrence' } }	--baseElements.orderBy=occurrence
{ selectors: [ { selector: 'img', format: 'skip' } ] }	--selectors[] {} :selector=img :format=skip
{ selectors: [ { selector: 'h1', options: { uppercase: false } }, { selector: 'h2', options: { uppercase: false } } ] }	--selectors[] {} :selector=h1 :!options.uppercase {} :selector=h2 :!options.uppercase
{ selectors: [ { selector: 'table', format: 'dataTable', options: { uppercaseHeaderCells: false } } ] }	--selectors[] {} :selector=table :format=dataTable :options.uppercase-header-cells=false
