Support for other languages

[ruizrube]

Hi all.

Is there any development guidelines on how to extend Codeql for supporting other programming languages?
Thanks

Hi @ruizrube, great to hear you're interested in expanding support for CodeQL 💪 What language(s) were you interested adding support for?

We don't have super detailed documentation on how to do this, but a good start would be to read this blog post on how we do extraction for Ruby: https://github.blog/2022-02-01-code-scanning-and-ruby-turning-source-code-into-a-queryable-database/

You should be able to use the same approach with using tree-sitter to get up and running with being able to query the raw AST produced by tree-sitter. Adding AST rewrite rules to get a clean API as well as data-flow support would take some effort.

I would strongly recommend that you join the GitHub Security Lab slack (request invite here) and join the #codeql-hacking channel, which was designed with this purpose of talking about CodeQL extensions and custom extractors (and has a few more resources).

Hi! Thank you for the pointers. I am evaluating whether implement support for the Blockly language serialized as XML files

Hi again. Since a Blockly program is managed as a XML file, I could analyze it, for example, as a Java program and using the XMLElement type ( https://codeql.github.com/codeql-standard-libraries/java/semmle/code/xml/XML.qll/type.XML$XMLElement.html). Isn't it?

I think all our of supported languages are able to extract XML as well (with the right commands), so yes, that should be doable 👍

Are there any folks who have done any work for Perl with CodeQL? I know that it's fun to poke fun at the older langauges, but there's still a significant Perl codebase out there and the SAST tool support available for Perl code is not very well maintained.

I deal in the world(s) of "dead languages" [How many here have done Algol, Fortran [IV and 77], Ada, or so many more].... It would be GREAT if there was some formal supported documentation as an extensibility guide/tutorial as I do not ever see if being viable for the product team(s) to invest in these areas......

[Heziode]

Oh no! You have flagged Ada as "dead language" 🥺.
In fact, it is still heavily used, but, in niche sectors, with industrial secrets / defense.

I support what you say. Documentation on support for new languages would be greatly appreciated.

Is there by chance a Roadmap of soon to be supported language stacks with CodeQL?

[smowton]

The public roadmap can be seen at https://github.com/orgs/github/projects/4247/views/1?filterQuery=label%3Acodeql

[kencrismoncw]

Awesome. Thanks!!! Get Outlook for iOS<https://aka.ms/o0ukef>

I used quotes for a reason to indicate that they are in fact used in various situations… thank you for your support <smile> From: Quentin Dauprat ***@***.***> Sent: Tuesday, March 26, 2024 8:27 AM To: github/codeql ***@***.***> Cc: David Corbin ***@***.***>; Comment ***@***.***> Subject: [External] Re: [github/codeql] Support for other languages (Discussion #8141) Oh no!
