Bruno BELANYI 60804f0ff0 Add object-oriented constructs
Another EPITA extension, although this is mentionned in the book.

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 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.

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.

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 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 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 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.
