Relative paths or environment variables in languages.toml

[andycarlberg]

There are some similar questions to this already in discussions but those discussions are closed and the proposed solutions don't work for my use case.

I'm trying to configure astro-ls which requires the location of the Typescript tsdk config variable. I need the config option to point to the global install of Typescript. I also manage my dotfiles in a Git repo to sync changes across machines. These machines will have different HOME directories depending on the username I have on the machine. In this example, I'm using mise to manage Node versions but the question applies to even a more standard install of Node.

[language-server.astro-ls]
command = "astro-ls"
args = [ "--stdio" ]
config = { "typescript" = { "tsdk" = "/home/<my-user>/.local/share/mise/installs/node/22/lib/node_modules/typescript/lib"}, "environment" = "node" }

How can I make this a more generic path? Tilde and environment variables aren't processed by Helix for now. Is that the only solution? Or is there a workaround to provide a generic path here?

Just discovered astro-ls is now configured by default (#12939) and thought I'd share here to spread awareness. It looks like the implementation expects 1) the present working directory to be the project root directory where node_modules is and 2) typescript to be installed in the project. This is probably the most common scenario and is good enough to cover my needs, but doesn't technically address the original request in this discussion to "point to the global install of Typescript".
