Tracking: language support requests (post-1.0 roadmap)

[colbymchenry]

codegraph parses code with tree-sitter, so adding a language is mostly: wire a grammar .wasm + a small per-language extractor, then validate retrieval on real repos. There's an /add-lang workflow and a contributor cookbook (see #97 / docs/ADDING-A-LANGUAGE.md).

This issue consolidates the individual language-support requests so they don't fragment the tracker ahead of 1.0. The individual issues are being closed and folded in here — 👍 a language below to signal demand, and PRs are very welcome (start from the closest existing extractor).

Currently supported: TypeScript/JavaScript, Python, Go, Rust, Java, Kotlin, Scala, C/C++, CUDA, C#, Visual Basic .NET, Swift, Objective-C, Metal, PHP, Ruby, Dart, Lua/Luau, R, Erlang, CFML, COBOL, Solidity, Terraform/OpenTofu (HCL), Svelte, Vue, Astro, Razor/Blazor, Liquid, Pascal/Delphi.

Requested (not yet supported):

Language	Issue(s)	Notes
BrightScript	#559
ReScript	#524
PLC Structured Text (SCL)	#441
Lazarus / Free Pascal	#340	Delphi (.pas / .dfm) is already supported; Lazarus FPC is close — please test current behavior
Nix	#332, #324
Verilog / SystemVerilog	#262
Julia	#229
Fortran	#200
Groovy	#169
dbt (Databricks)	#88
SQL	#85
ArkTS (.ets)	#512, #396, #890	TS superset — likely works via the TS extractor once .ets is in file discovery; please test
HTML / Jinja2 templates	#431	FastAPI server-side rendering
AUTOSAR C/C++ (heavy macros)	#557	More a C/C++ macro-expansion gap than a new grammar
GLSL	#685	Graphics shaders; mature community tree-sitter grammars exist
QML	#759	Qt C++/QML apps — the C++↔QML bridge (qmlRegisterType, signals/slots) is the valuable part
ABAP / abapGit	#694	Serialized .clas.abap / .intf.abap / .prog.abap objects
Slint	#916
MQL5	#55	MetaTrader; C++-like, reporter offered a PR
Shell / Bash (& PowerShell)	#239	Mature Bash tree-sitter grammar exists

Prioritization will be roughly by 👍 + PR availability. Contributions welcome — this is one of the easiest areas to land a PR.
