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`.

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

The gammar itself is quite basic, but is much better than nothing
for working with real files consisting mostly of html.

* add tree-sitter-regex
* adapt regex highlights from upstream
* inject regex into elixir sigil_r/2 and sigil_R/2
* generate lang-support docs
* capture interesting nodes in character-ranges
* make $.character_class captures more consistent
* fix fallthrough behavior for character classes
* capture pattern characters as 'string'
* use latest tree-sitter-regex
* set elixir regex injections as combined
* add link to upstream queries
* inject regex in rust into 'Regex::new' raw string literals
Indentation of single line statements doesn't work, i.e.
for (;;)<hit enter>
leads to
for(;;)
<cursor here>
Only blocks with curly braces are indented.
* Add injection regex for more languages
To support embedding them in other languages like markdown.
* Add llvm-mir highlighting
LLVM Machine IR is dumped as yaml files that can embed LLVM IR and
Machine IR.
To support this, add a llvm-mir-yaml language that uses the yaml
parser, but uses different injections to highlight IR and MIR.
* Update submodule with fixed multiline comments

Add a tree-sitter grammar and highlights for TableGen files.
TableGen and its grammar are described here:

* add submodule on tree-sitter-rebase, add to languages
* add basic highlights query
* inject bash in execute statements
* update tree-sitter-rebase
* tree-sitter-rebase->tree-sitter-git-rebase
* get injection working with tree-sitter-git-commit
* set scope under source.gitrebase
* unset include-children on commit message injections
* Revert "unset include-children on commit message injections"
This reverts commit 2ecee155ea8e229651920b291062c2ee84b47944.
* fix generated language docs
* use rebase_command scopes from tree-sitter-git-commit
* add submodule on tree-sitter-git-diff
* add git-diff highlights
* inject git-diff into git-commit
* update tree-sitter-git-commit with fix for bad diff case
* add git-diff to language support docs
* include-children in diff injections
This ensures that children nodes of $.message are included in the
injection, such as $.user or issue/pr numbers. Without this change,
diffs containing '#' or '@' characters can trip up the injection and
be parsed separately.
See https://github.com/helix-editor/helix/pull/1373#issuecomment-1001215629
* set diff language's scope as source.diff
* Improve llvm highlighting and queries
The llvm tree-sitter parser was updated to support scopes and more
accurate highlighting.
* Group highlight expressions better
- Differentiates between `as` keyword as a binary type cast
operator and import renamer.
- `mod` and `use` are now under `@keyword.control.import`,
but `mod` is a `@keyword` if used as `mod name;`.
* allow language.config (in languages.toml) to be passed in as a toml object
* Change config field for languages from json string to toml object
* remove indents on languages.toml config
* fix: remove patch version from serde_json import in helix-core
* Use same tree-sitter-zig as upstream/master
* fix(completion_popup): Fixes#1256

- Rename markup.underline.link to markup.link.url
- Add markup.link.label
- Add markup.quote
(The constructor theme scope was missing from the
docs, so unrelated to this commit).
* Add language: dart
The setup requires that dart be in the users path, such as:
```
export PATH="$HOME/Android/flutter/bin/cache/dart-sdk/bin/:$PATH"
```
Refactor the dart highlights
* lang: dart: add indents and locals
* lang: dart: corrections to local scope

* Add treesitter textobject queries
Only for Go, Python and Rust for now.
* Add tree-sitter textobjects
Only has functions and class objects as of now.
* Fix tests
* Add docs for tree-sitter textobjects
* Add guide for creating new textobject queries
* Add parameter textobject
Only parameter.inside is implemented now, parameter.around
will probably require custom predicates akin to nvim' `make-range`
since we want to select a trailing comma too (a comma will be
an anonymous node and matching against them doesn't work similar
to named nodes)
* Simplify TextObject cell init
* add submodule on tree-sitter/tree-sitter-tsq
mark tsq submodule as shallow
* add tree-sitter-tsq to languages
* add highlight queries for tsq
* Update .gitmodules

Can't do it via a scm query nicely because it returns an iterator over
all the matches, whereas we want to traverse the tree ourselves.
Can't extract the pattern data from a parsed query either.
Oh well, toml files for now.
