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.
The new revision handles a case that I come across often: a stab
clause (i.e. '->') with an empty right hand side:
Enum.map(xs, fn x ->
end)
The old version would parse the "end" token as an error.
This is technically valid syntax but more importantly it comes up
very often when editing, and the old revision would flicker between
the keyword highlight and the warning highlight.
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
Here we perform a shallow fetch using builtins.fetchTree. In order
to make this work, we need to specify the `ref' for any repository
that doesn't have `master' as its default branch (I'm not sure why
this limitation exists since we don't need this when performing
the shallow fetch in `--grammar build')
This `ref' field is ignored by helix, so I have left it undocumented
for now, but I could be open to documenting it.
This is a rather large refactor that moves most of the code for
loading, fetching, and building grammars into a new helix-loader
module. This works well with the [[grammars]] syntax for
languages.toml defined earlier: we only have to depend on the types
for GrammarConfiguration in helix-loader and can leave all the
[[language]] entries for helix-core.
Here we add syntax to the languages.toml languge
[[grammar]]
name = "<name>"
source = { .. }
Which can be used to specify a tree-sitter grammar separately of
the language that defines it, and we make this distinction for
two reasons:
* In later commits, we will separate this code from helix-core
and bring it to a new helix-loader crate. Using separate schemas
for language and grammar configurations allows for a nice divide
between the types needed to be declared in helix-loader and in
helix-core/syntax
* Two different languages may use the same grammar. This is currently
the case with llvm-mir-yaml and yaml. We could accomplish a config
that works for this with just `[[languages]]`, but it gets a bit
dicey with languages depending on one another. If you enable
llvm-mir-yaml and disable yaml, does helix still need to fetch and
build tree-sitter-yaml? It could be a matter of interpretation.
* impl auto pairs config
Implements configuration for which pairs of tokens get auto completed.
In order to help with this, the logic for when *not* to auto complete
has been generalized from a specific hardcoded list of characters to
simply testing if the next/prev char is alphanumeric.
It is possible to configure a global list of pairs as well as at the
language level. The language config will take precedence over the
global config.
* rename AutoPair -> Pair
* clean up insert_char command
* remove Rc
* remove some explicit cloning with another impl
* fix lint
* review comments
* global auto-pairs = false takes precedence over language settings
* make clippy happy
* print out editor config on startup
* move auto pairs accessor into Document
* rearrange auto pair doc comment
* use pattern in Froms
* 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
This commit builds on #1460, #1571, and others, adding the .zshenv
file and all files with the zsh extension to the file-types using
bash syntax-highlighting.
After the changes to upgrade and reenable tree-sitter-haskell #1417
for the purpose of enabling Haskell syntax highlighting #1384, we
might as well take the final step.

To support this, add a llvm-mir-yaml language that uses the yaml
parser, but uses different injections to highlight IR and MIR.

diffs containing '#' or '@' characters can trip up the injection and
be parsed separately.

In the PHP community, 4 spaces is widely considered the default, as
it is recommended by the PSR-2 and PSR-12 standards, as well as popular
derivative standards like those for Laravel and Symphony.

* Use same tree-sitter-zig as upstream/master
As discussed in #809 ; I also have a [tree-sitter implementation](https://github.com/jamesnvc/tree-sitter-prolog), but for reasons discussed in the linked post, I kind of gave up on that sort of static approach for making a general-purpose Prolog grammar (since it has a very flexible syntax and allows defining new operators with new precedences dynamically).
That being said, the LSP implementation here at least shows documentation and does support the semantic token API, so when Helix supports that, this should also provide highlighting.
* Added option to provide a custom config file to the lsp.
* Simplified lsp loading routine with anyhow
* Moved config to language.toml
* Fixed test case
* Cargo fmt
* Revert now-useless changes
* Renamed custom_config to config
