Custom injection query

[mydumpfire]

Support for user-level injection queries. This would allow you to add your own custom queries without having to modify HELIX_RUNTIME (which may not be modifiable, e.g. NixOS). Perhaps it can be located in ~/.config/helix/queries/*.

We consider the queries in directory configuration files. You can put queries in .config/helix/runtime and they will take priority over the runtime files provided by the package manager

[mydumpfire]

Can you extend the default queries instead of overwriting them? In neovim, you can add ; extends to the top of the query file. Is there an equivalent for Helix?

[pascalkuthe]

No you need to copy them

[mydumpfire]

Can this issue be re-opened as a request for query extension support instead? Query files can be hundreds lines long, so extensibility would be really convenient.

I think this could be convenient. The design is a little tricky because there are multiple use-cases here for having custom queries in your ~/.config/helix/runtime / HELIX_RUNTIME. You might be extending the existing queries or you may have changed / updated the parser and want to ignore the existing queries. ; extends could work but it would only prepend/append the query text to the old queries which means that you won't have any control over the priorities of the patterns. So this might need a priority system like neovim has for queries, which I'd like to avoid if we can. Copying the old queries and making changes to that is a little clunky but it's probably the most straightforward way to change queries without introducing a bunch of new features just for merging queries.

Plus one for extension! 😊

In neovim, you can add ; extends to the top of the query file. Is there an equivalent for Helix?

I wanted to try to contribute some queries, and followed documentation - added HELIX_RUNTIME in my .bashrc and also created a ~/.config/helix/runtime but those did nothing at all?
I presume if you are on NixOS it does not work? as @mydumpfire said
even though @pascalkuthe said: "qeries in .config/helix/runtime and they will take priority over the runtime files provided by the package manager" - it still didn't take any effect?
Or maybe I am doing something wrong....

UPD: I do think that no matter what I change in my ~/.config/helix/runtime with HELIX_RUNTIME in my paths, the highlighting is all the time default. I tried to modify the package manager's version in nix/store but those files are read-only

UPD2: Sorry, you were right, I was testing my queries in .config/helix/runtime - and they did not work.
You have to test them in .config/helix/runtime/queries/<language> - and now it works!
