* A new predicate called `fold.invalidateOnChange` that can be used when a change should automatically invalidate the fold cache for each row in a node's range.
* The ability to use custom predicates in `folds.scm` files. (Previously, captures from `folds.scm` did not consult an instance of `ScopeResolver` in the processing phase.)
…such as in multi-line self-closing tags and multi-line opening tags.
Also fix an issue in fold handling that made it impossible to use `@_IGNORE_` captures in `folds.scm`.
Changes:
* `#define FOO 1` and `#define FOO` will _always_ scope `FOO` as `constant.other.c`, even when `FOO` is mixed-case or lower-case.
* `#define FOO()` will _always_ scope `FOO` as `entity.name.function.preprocessor.c`, even when `FOO` is mixed-case or lower-case.
* Usages of bare identifiers in other contexts in preprocessor directives should always scope them as `constant.other.c` — unless I’m made aware of any counterexamples where that shouldn’t happen. For example: in `#if TABLE_SIZE > 200`, `TABLE_SIZE` should always be `constant.other.c`, no matter its casing.
* All-caps variable declarations and assignments (`int FOO = 0`, etc.) should scope `FOO` as `variable` rather than `constant`. We should only scope an arbitrary identifier as `constant` if we think it’s been used in the context of a macro definition.
However:
* When deciding whether something outside of a directive refers to a macro constant, we have no choice but to use the `ALL_CAPS` heuristic. Ideally we’d be able to determine that from some sort of analysis of the source code files — but even if we could keep track of that sort of thing in a single buffer, it’d fall down when macro constants _defined in other files_ are used. All we can do here is make a best guess.
This code snippet sets up logging so that a worker process can call `console.log` and its siblings and have them show up in the renderer process’s console… but it’s trying to destructure the antiquated magical `arguments` collection (which is like an array, but isn’t an array!) and the engine doesn’t seem to like it.
Logging didn’t work for me until I changed this.
This is such a tiny fix, and I don’t have the energy to shelve everything on this branch just to make a separate PR.
…no matter how deeply they’re nested.
Also highlight `?` in an incomplete ternary.
(Also fix a lot of final segments in the TypeScript highlights file; I’ve been lazily copying-and-pasting and forgetting to change them.)
We are crossing the Rubicon.
https://github.com/orgs/pulsar-edit/discussions/249 is a discussion of specific ways that indentation is different in JavaScript because of the new grammar. We intentionally didn’t try to preserve the indentation decisions in the old TextMate grammar, but this is (predictably) disruptive to some people. We don’t want to punt like legacy Tree-sitter did and rely on the TextMate grammar’s coarse regexes to decide what gets indented, but we can at least make the new indentation system granularly configurable.
This commit makes practically every indentation decision configurable in JavaScript and TypeScript. It groups these settings under a new “Indentation” section in each package’s settings.
I might decide that this goes too far and roll back the granular settings for `{`, `[`, and `(`, but the other indentation hints are absolutely matters of taste, so it’s only proper that users can choose to disable them.
In the long run, we could _consider_ allowing users to swap in another indentation engine altogther, much like #895 proposes for folds. That would let us legitimately offer users a way to opt into “the way the TextMate grammar does it” without affecting other users.
Another stopgap option would be to add a way for a user to disable indentation hinting altogether for a given grammar.
…when a project-specific config is present.
Most people don't use a project-specific config, which is why this bug has been present for ages. Read the new spec for an explanation.
…by namespacing them as `@_IGNORE_.foo`, `@_IGNORE_.bar`, etc.
It's sometimes necessary to define a capture in a query not because you want to apply a scope name, but because you need to use it as the argument to a predicate. `@_IGNORE_` was intended for that purpose, but it was the _only_ capture name with that special effect.
Now, you can specify any number of captures that don't apply scope names. As long as it equals `@_IGNORE_` or _starts with_ `@_IGNORE_.`, it'll have the same effect. This lets you target two or more nodes and use them all in predicates in the same query without any of them applying a scope name.
There's a hard-to-grok setting for language injections that allows a deeper layer to monopolize the scope application for a range. In most cases, an injection is placed into a node that the parser doesn't know much about (like a `script` block in HTML); but Rust and C parsers needed a way to inject themselves _into themselves_ so that they could add syntax highlighting to macros. Because they were applying highlighting to a range that the base layer _already_ had plans to highlight, they needed a way to block the shallower layer from acting.
This mode has never worked briliantly, but it's been made smarter in several ways since the invention of modern Tree-sitter. And here's another one: if the highlight iterator is at a position where an injection range is _about_ to begin, it shouldn't be able to stop any other layer from _closing_ a scope; and if the highlight iterator is at a position where an injection range has just _finished_, it shouldn't be able to stop any other layer from _opening_ a scope.
Because of this, we can now fix a bug that I think might've been present for a while in the application of scopes to rust macros like `println!` — the position after the exclamation point is one of those injection-layer boundaries, to the effect that a scope name was opened that would persist until at least the end of the screen line.
…which locked its return values to integers.
The other language modes allow this method to return a non-integer, hence so should we. If this breaks something, it can be addressed some other way.
* Revert JSDoc tags to use the `keyword` namespace
* Ensure we always apply `meta.tag.jsx.js` to the area surrounding a JSX opening/closing/self-closing tag element and its punctuation.
* Declared namespaces should be `entity` only, not `support`
* `<` and `>` in type parameters should always have the proper `punctuation` scopes applied
* All TSX tags should have the surrounding `meta.tag.ts.tsx` scope applied
* TSX fragments (`<>`) should be highlighted
…when inside of a TS block within a TSX interpolation.
Some mixing of TS and TSX is too ambiguous for the “Toggle Line Comments” command, but in this case we've got a brace-delimited block inside of a TSX interpolation. That's practically guaranteed to mean we've got a line with _only_ TypeScript on it, so we should use an ordinary TS line comment.
