Try to fix indentation for <template> ... </template>

[NullVoxPopuli]

Currently, when I press Enter in a

// test.gjs
<template>

</template>

block,
the cursor goes all the way to the left, rather than being indented.

I'm still trying to figure out how to test things locally, so this isn't ready for review or merge.

Are you sure? I think it's just the filetype being incorrect here.

test.gjs shows javascript.glimmer as the filetype, not glimmer

[NullVoxPopuli]

correct -- maybe I need to configure an offset? (I don't know how to do that)
Right now, tree-sitter-glimmer has no idea if it's being used between <template>...</template> or not

[lucario387]

But tree-sitter-glimmer do know though? It's the fact that javascript.glimmer filetypes do not get the automatic vim.bo.indentexpr=v:lua.require('vnim-treesitter').indentexpr()

Consider adding a line of vim.treesitter.language.register("glimmer", {"javascript.glimmer"}) somewhere in your file.

[NullVoxPopuli]

I don't think that's correct. tree-sitter-glimmer is for the sub-language within <template> ... </template>, not the whole gjs file.

(#set! injection.language "glimmer"))

Consider adding a line of vim.treesitter.language.register("glimmer", {"javascript.glimmer"}) somewhere in your file.

Is this something other language libraries do? (registering themselves?)
Or is this only done to override associations with parsers?

If so, tree-sitter-javascript is the correct parser for gjs.
But maybe I misunderstand what that register command does? how does it relate to the indentexpr? Is that something I should PR to tree-sitter-glimmer?

One thing I've been trying to figure out, is where is the right place to fix indentation of

const Two = <template>|</template>;

(press enter)

const Two = <template>
|</template>;

it should be this instead:

const Two = <template>
  |
</template>;  

something needs to tell the inner syntax (tree-sittter-glimmer) to offset all indentation by an additional $OFFSET_SIZE (whatever that is)

when I created this PR, I didn't notice that I had a conflicting indent plugin installed (conflicting may be a bit strong), but best to test without. I've disabled https://github.com/VidocqH/auto-indent.nvim

That's not really because of the indentexpr.
Auto newlining the end template tag is the formatexpr's thing
