Bruno BELANYI 21172e21e7 Fix assignment priority 
The assignment operator is lower priority than any other binary
operator.

Otherwise the following:

```tiger
a := b | c
```

Would be parsed as:

```tiger
(a := b) | c
```

Instead of the expected:

```tiger
a := (b | c)
```

Bruno BELANYI 572dab6f4b Add meta-variables 
This is an EPITA extension of the language, used mostly by internal
compiler machinery.

Bruno BELANYI 1cfcc43469 Add queries to rust bindings
continuous-integration/drone/push Build is passing Details 
I should try using those bindings to write tests for currently untested
queries...

Once again, something that isn't testable with 'tree-sitter' tooling...
 2022-06-04 10:43:35 +02:00
Bruno BELANYI 2bd24cceb4 Add folds 
Unfortunately it seems like this is not really testable with the
'tree-sitter' tooling.

If I want to check that this is working correctly, I should explore how
to make use of, e.g., neovim to automate testing.

Bruno BELANYI 545d090540 Mark 'comment' as injecting 'comment' 
Neovim defines queries for the 'comment' language, to match 'TODO',
'FIXME', etc...

Bruno BELANYI efe0a2800b Add comment about 'locals' queries limitations 
This is not enough of an issue to avoid using the functionality however,
for example variable declarations are thankfully not affected by this
issue, since they *must* be declared before their use.

Not sure why it seems like the 'is-not? local' is not working.

Will investigate later

Bruno BELANYI 2d89ec8b20 Add built-in functions
continuous-integration/drone/push Build is passing Details 
This is a good proxy test to ensure that scope queries work correctly.

Bruno BELANYI 64ff9dd944 Add import path high-lighting 
I don't think this group is supported by neovim, but 'tree-sitter-nix'
makes use of it, and I think it makes sense to add it.
 2022-06-03 20:35:53 +02:00
Bruno BELANYI bd42c2c9c1 Move 'literals' high-lighting to end of file 
Once again, seems like order matters, and I want to be able to write more specific queries.

Bruno BELANYI aff11eefce More specific loop keyword high-lighting 2022-06-03 20:28:28 +02:00
Bruno BELANYI b22ca8cd67 More specific function keyword high-lighting 
I learnt about this group by reading the nvim-treesitter source [1].

Bruno BELANYI b998075f2d Use play-ground enabled 'tree-sitter' in devShell 
This is actually quite useful for debugging it turns out :-).

Bruno BELANYI 67b555c381 Move 'misc' high-lighting to end of file 
Turns out that order *matters* for queries.

Tree-sitter will stop at the first match it seems. So I want the
hyper-general 'identifier' matching right at the end to avoid overriding
more specific rules.

Bruno BELANYI 752f941589 Fix 'nix flake check'
continuous-integration/drone Build is passing Details 
Turns out that 'tree-sitter' is not wrapped to have node and a compiler
available, because nixpkgs assumes that grammars already include
generated files.

So wrap it manually and use that in our pre-commit/checks.
 2022-06-03 16:00:13 +02:00
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 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.

Bruno BELANYI 2be5056793 Add 'type_identifier' alias 
This is more appropriate, and actually closer to the specified grammar.
