Prism is a lightweight, robust, elegant syntax highlighting library. It's a spin-off project from Dabblet.

Why another syntax highlighter?
Prism depends on community contributions to expand and cover a wider array of use cases. If you like it, considering giving back by sending a pull request. Here are a few tips:
- Read the documentation. Prism was designed to be extensible.
- Do not edit
prism.js
, it’s just the version of Prism used by the Prism website and is built automatically. Limit your changes to the unminified files in thecomponents/
folder.prism.js
and all minified files are also generated automatically by our build system. - The build system uses gulp to minify the files and build
prism.js
. With all of Prism's dependencies installed, you just need to run the commandnpm run build
. - Please follow the code conventions used in the files already. For example, I use tabs for indentation and spaces for alignment. Opening braces are on the same line, closing braces on their own line regardless of construct. There is a space before the opening brace. etc etc.
- Please try to err towards more smaller PRs rather than few huge PRs. If a PR includes changes I want to merge and changes I don't, handling it becomes difficult.
- My time is very limited these days, so it might take a long time to review longer PRs (short ones are usually merged very quickly), especially those modifying the Prism Core. This doesn't mean your PR is rejected.
- If you contribute a new language definition, you will be responsible for handling bug reports about that language definition.
- If you add a new language definition or plugin, you need to add it to
components.json
as well and rebuild Prism by runningnpm run build
, so that it becomes available to the download build page. For new languages, please also add a few tests and an example in theexamples/
folder. - Go to prism-themes if you want to add a new theme.
Thank you so much for contributing!!
