A few changes:
* 0-arity type specs like the following previously would not have the
expected 'variable.parameter' highlighting for the return type:
-spec foo() -> Value when Value :: term().
* Highlight module, type and function docs as documentation comments
and inject markdown into them.
* Replace `#match?` predicates with `#any-of?` where possible.
* Remove custom auto-pairs. Now that Erlang uses markdown for
documentation, the asciidoc-style backtick-singlequote pair is no
longer useful.
* Macros that start with underscore were incorrectly marked as
'comment.unused' rather than 'keyword.directive' due to an ordering
issue of those two patterns.
* Recognize escripts as Erlang by the shebang.
This doesn't work robustly (within pattern matches). Only regular
bindings are highlighted as parameters. In order to highlight all
parameters even in matches, we would need an arbitrary nesting operator
in queries which doesn't exist yet in tree-sitter.
This highlights edoc within Erlang comments. The trick was to have
the Erlang grammar consume newlines and then give them to EDoc in the
injection to use so that line-wise elements could be parsed accurately.
For example
-record(state, {})
Would not highlight `state` as a type since the alternation didn't
allow for an empty tuple. Allowing the inner atom of the tuple to be
optional fixes this case.
You might use a macro like `?MODULE` to name a record:
-record(?MODULE, {a, b, c}).
With this fix, the record fields correctly get `variable.other.member`
highlights.
The '#' character may either be interpreted as a map when used
like so:
%% Example 1
#{a => b}
Or as an operator which updates an existing map when the left-hand
side is an expression:
%% Example 2
MyMap#{a => b}
This commit changes the highlight to `punctuation.bracket` when used
as a character in a literal map (example 1) and keeps the `operator`
highlight when used for updating (example 2).
The update to the grammar itself covers the case where the document
is a single expression without a trailing newline such as "min(A, B)".
A small change to the parser now parses these expressions correctly
which improves the display of the function head in the signature
help popup.
The update to the queries marks 'andalso', 'orelse', 'not', etc. as
`@keyword.operator` which improves the look - it looks odd to see
operators that are words highlighted the same as tokens like '->'
or '=:='.
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
