Note to editors:

Please do not edit the above list manually.

• Just because you type something in and it looks like it's highlighted correctly does not mean the identifier actually exists in the system. Keep in mind that invalid identifiers trigger an automatic language detection in the editor preview (they will result in no highlighting in the submitted post).

• Not all the languages supported by highlight.js are available everywhere. The set of languages available depends on how the library is built or included. This means that several languages that are indicated as supported in the above linked list are not supported by Stack Exchange's version of highlight.js, as they are in separate modules which have not been deployed on Stack Exchange.

Because of these points, to update the list please use the script it was generated with and link to this script (or another Meta post which confirms an identifier's existence) in your edit summary.

Keep in mind that Stack Exchange does not maintain this syntax highlighter (aside from installing newer versions of it), and posting bug reports or feature requests concerning it here on Meta will not get them fixed or implemented.

Any language identifiers used in a post that go unrecognized, are for languages that are not deployed on Stack Exchange, or are for tags that do not have a language hint specified in their data will be ignored and the code block will not be highlighted. Prior to October 2024, such identifiers would trigger an automatic language detection; however, at that time, this was changed so it no longer highlights on new and edited posts (older unedited posts weren't changed). Note that the editor preview still continues to use automatic language detection in this case; the above fix was only for submitted posts.
