Bruno BELANYI 02f89ac524 Refactor nix package 
Introduce an overlay, and use the existing 'tree-sitter' package
machinery to extend it with this grammar.

Expose the extended 'tree-sitter' as part of the flake packages.

Bruno BELANYI 964d796b4b Fix 'nix flake check' evaluation 
I should figure out why 'pre-commit' even needs dotnet at some point...

Bruno BELANYI 0b17386cad Add ':=' to 'operator' 2022-06-03 11:42:57 +02:00
Bruno BELANYI 82bbebeeb5 Inline '_function_declaration_common' 
This is purely an de-duplication rule, we don't need to make it part of
the parse tree.
 2022-06-03 10:59:54 +02:00
Bruno BELANYI 0b549493a2 Add identifiers high-lighting 
We now make use of the more specific '_type_identifier' and
'_field_identifier' rules!
 2022-06-03 10:44:10 +02:00
Bruno BELANYI da494122ea Replace '_typed_field' by more specific grammar 
Instead of re-using a common rule, inline its definition and use
'_field_identifier' where appropriate.

This is useful for more accurate high-lighting.
 2022-06-03 10:40:14 +02:00
Bruno BELANYI 5d37bf7bd1 Use 'type_identifier' in array type declaration 2022-06-03 10:35:53 +02:00
Bruno BELANYI 0827093fe7 Add 'field_identifier' alias 
This will be useful for high-lighting.
 2022-06-03 10:31:30 +02:00
Bruno BELANYI abe5b2e366 Add 'misc' grouping 2022-06-03 10:16:44 +02:00
Bruno BELANYI 2be5056793 Add 'type_identifier' alias 
This is more appropriate, and actually closer to the specified grammar.

Bruno BELANYI 751929a058 Fix whitespace skipping in scanner 
Once again, implicit fall-through is the devil.

Bruno BELANYI b9376ccd35 Add comment syntax highlighting 2022-06-02 22:20:37 +02:00
Bruno BELANYI 84d25af8d5 Add language information to 'package.json' 
Apparently this is needed by the 'tree-sitter' tooling for syntax
highlighting.
 2022-06-02 22:20:37 +02:00
Bruno BELANYI 5866cd4a82 Add 'tree-sitter' pre-commit hook 
Make sure you don't break anything when committing.
 2022-06-02 22:20:37 +02:00
Bruno BELANYI b3e91d9aad Add 'tree-sitter-files' pre-commit hook 
This is too ensure that generated files are always in lock-step with the
grammar.
 2022-06-02 22:20:37 +02:00
Bruno BELANYI 8f752e0f94 Add 'clang-format' pre-commit hook 2022-06-02 22:20:37 +02:00
Bruno BELANYI 5be01b43fb Add clang-format rules 
Since we now have an external scanner, might as well have good looking
code.
 2022-06-02 22:20:37 +02:00
Bruno BELANYI 50a0eaa071 Add support for nested comments 
Unfortunately, the 'extras' array expects single tokens only, so one
can't really use a recursive parsing rule to express nesting comments...
 2022-06-02 22:20:37 +02:00
Bruno BELANYI 75bb2c7009 Add comments 
For now it only supports non-nested comments. It seems like I *will*
need to write an external lexer to account for nesting properly.

Bruno BELANYI e5e958cac9 Add tests for sequence expressions 2022-06-02 17:07:30 +02:00
Bruno BELANYI e59aeed31a Remove nested 'parameters' field 
The 'parameters' production rule does not need itself to have a
'parameters' field, this is redundant information.

Bruno BELANYI 02f83784b1 Use explicit 'nil_literal' rule 
Makes the dumped AST more readable, and will probably help in writing
future queries.
 2022-06-02 17:07:30 +02:00
Bruno BELANYI 0bc7e59fc7 Disable keyword extraction 
For now bare keywords are errors, since we have not included them as
valid expressions.
 2022-06-02 17:07:30 +02:00
Bruno BELANYI 50c8e3c0e6 Centralise precedence values 
Makes it easier to ensure correct precedence relative to the rest of the
grammar later on.
