HEEx is a templating engine on top of Elixir's EEx templating
language specific to HTML that is included in Phoenix.LiveView
(though I think the plan is to eventually include it in base
Phoenix). It's a superset of EEx with some additional features
like components and slots.
The injections don't work perfectly because the Elixir grammar is
newline sensitive (the _terminator rule). See
https://github.com/elixir-lang/tree-sitter-elixir/issues/24
for more information.
This will become more important with the HEEx grammar being added.
Error highlighting with the Elixir grammar is a bit jumpy because
in some scenarios, a bit of missing syntax can force tree-sitter to
give up on error recovery and mark the entire tree as an error.
This ends up looking bad when editing. We don't typically highlight
error nodes so I'm inclined to leave it out of the highlights here.
After the incremental parsing rewrite for injections (which was released
in 22.03 https://helix-editor.com/news/release-22-03-highlights/#incremental-injection-parsing-rewrite),
we can now do combined injections which lets us pull in some templating
grammars. The most notable of those is embedded-template - a pretty
straightforward grammar that covers ERB and EJS.
The grammar and highlights queries are shared between the two but they have
different injections.
It looks like a24fb17b2a (and
855e438f55) broke the typescript
highlights because typescript
; inherits: javascript
but it doesn't have those named nodes in its grammar.
So instead we can separate out JSX into its own language and copy
over everything from javascript and supplement it with the new
JSX highlights. Luckily there isn't too much duplication, just the
language configuration parts - we can re-use the parser with the
languages.toml `grammar` key and most of the queries with `inherits`.
* WIP: Rework indentation system
* Add ComplexNode for context-aware indentation (including a proof of concept for assignment statements in rust)
* Add switch statements to Go indents.toml (fixes the second half of issue #1523)
Remove commented-out code
* Migrate all existing indentation queries.
Add more options to ComplexNode and use them to improve C/C++ indentation.
* Add comments & replace Option<Vec<_>> with Vec<_>
* Add more detailed documentation for tree-sitter indentation
* Improve code style in indent.rs
* Use tree-sitter queries for indentation instead of TOML config.
Migrate existing indent queries.
* Add documentation for the new indent queries.
Change xtask docgen to look for indents.scm instead of indents.toml
* Improve code style in indent.rs.
Fix an issue with the rust indent query.

news:
- tree-sitter-elixir now powers Elixir syntax highlighting on github.com
- GitHub now supports code-navigation for Elixir repos via
tree-sitter-elixir
changes:
- modules now use the `@module` highlight, which was added upstream to
tree-sitter
- it seems appropriate to use `@namespace` to follow helix convention
- added nullary range operator (e.g. `Enum.to_list(..) == []`), a new syntax
for elixir 1.14
- a fix for stab clause nodes mis-highlighting when the right hand side of
the stab clause contained multiple simple expressions
changes:
- typed fields within records which do not declare a default
value are now correctly highlighted as record fields
- the EEP49 'maybe' form is now parsed
- fixes for highlights for 'begin' and 'after' tokens
changes:
- any text following a (scissors) is now contained in one (message)
- this vastly improves performance on large verbose commits:
no more slowness on huge commits
* Add kotlin language
Queries taken from https://github.com/nvim-treesitter/nvim-treesitter/blob/master/queries/kotlin seem to work well enough for my needs though I don't use kotlin heavily.
* Update lang-support doc
* Updates the kotlin highlight query to use helixs scopes
* Updates the queries from PR feedback
* Adds 'shallow = true' to gitmodules
* Removes kotlin locals.scm
* Remove blank line

* Add tree-sitter-twig grammer and highlights
The gammar itself is quite basic, but is much better than nothing
for working with real files consisting mostly of html.
* Docgen for newly added grammar
