- Language contributor checklist
- ==============================
- 1. Put language definition into a .js file
- ------------------------------------------
- The file defines a function accepting a reference to the library and returning a language object.
- The library parameter is useful to access common modes and regexps. You should not immediately call this function,
- this is done during the build process and details differ for different build targets.
- ::
- function(hljs) {
- return {
- keywords: 'foo bar',
- contains: [ ..., hljs.NUMBER_MODE, ... ]
- }
- }
- The name of the file is used as a short language identifier and should be usable as a class name in HTML and CSS.
- 2. Provide meta data
- --------------------
- At the top of the file there is a specially formatted comment with meta data processed by a build system.
- Meta data format is simply key-value pairs each occupying its own line:
- ::
- /*
- Language: Superlanguage
- Requires: java.js, sql.js
- Author: John Smith <email@domain.com>
- Contributors: Mike Johnson <...@...>, Matt Wilson <...@...>
- Description: Some cool language definition
- */
- ``Language`` — the only required header giving a human-readable language name.
- ``Requires`` — a list of other language files required for this language to work.
- This make it possible to describe languages that extend definitions of other ones.
- Required files aren't processed in any special way.
- The build system just makes sure that they will be in the final package in
- ``LANGUAGES`` object.
- The meaning of the other headers is pretty obvious.
- 3. Create a code example
- ------------------------
- The code example is used both to test language detection and for the demo page
- on https://highlightjs.org/. Put it in ``test/detect/<language>/default.txt``.
- Take inspiration from other languages in ``test/detect/`` and read
- :ref:`testing instructions <basic-testing>` for more details.
- 4. Write class reference
- ------------------------
- Class reference lives in the :doc:`CSS classes reference </css-classes-reference>`..
- Describe shortly names of all meaningful modes used in your language definition.
- 5. Add yourself to AUTHORS.*.txt and CHANGES.md
- -----------------------------------------------
- If you're a new contributor add yourself to the authors list.
- Also it will be good to update CHANGES.md.
- 6. Create a pull request
- ------------------------
- Send your contribution as a pull request on GitHub.
