2024-12-21Combine "CompiledGrammar" and "Report" payloadsEuAndreh4-66/+26
Instead of one JSON file for each output, a single file with both outputs combined, each under its own key. The beauty of maps. Also instead of using a flag to determine where to put the data, just print to stdout and be done with it.

2022-11-12Set token positions for the EOF symbolRyo Nihei2-3/+3
vartan intentionally had not set positional information for the EOF symbol in a token because the corresponding character does not exist in the source code. However, to be able to include the positional information in a syntax error message when a syntax error occurs due to the detection of the EOF symbol during parsing, this commit sets the position next to the last character in the source code as the position of the EOF symbol.
2022-11-12Fix counting of token positionsRyo Nihei1-37/+46
The name `unread` gives the impression of operating just the opposite of `read`. However, this commit renames `unread` function to `revert` because it was a function to revert the state to the last acceptance.

2022-08-06Remove underscore syntax matching any symbolRyo Nihei3-59/+8
Underscore syntax: For instance, a tree `(expr (id 'a') (add '+') (_))` matches both source codes `a + b * c` and `a - b / c`. This feature is helpful because it allows you to emphasize the main points of the test by ignoring nodes of no interest. However, we will remove the feature for the time being to reconsider the grammar.

2022-06-12Prohibit using a pattern in an alternativeRyo Nihei6-19/+102
When a syntax error occurs, the parser must provide a user with the names of expected tokens. However, if a pattern appears directly in an alternative, Vartan cannot assign an appropriate name to the pattern. Therefore, this commit prohibits alternatives from containing patterns.

2022-05-15Prohibit applying #left, #right, #assign, and #prec to an error symbolRyo Nihei2-14/+103
The shift of the error symbol is an operation forced by the driver. Therefore it is impossible to change this behavior by giving precedence to the error symbol. If we desire to change the precedence of a production rule with the error symbol, we can use #prec directive.
