# MRY
> IMPORTANT:
> This project is developed using zig version `0.14.1`.
> Since the zig std is changing between releases it is recommended to use this version.
## Grammar Files
The grammar file needs to be in the following format:
```
main -> expression
expression -> binary_operation | number | '(' expression ')'
binary_operation -> expression binary_operand expression
binary_operand -> '+' | '-' | '*' | '/'
number -> digit number | digit
digit -> '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9'
```
Where all terminals are in single-quotes and the rest are non-terminals.
> NOTE:
> The default entry point name is always `main` if you want to use
> a different one, use the `-e` or `--entry` option.
## Running Benchmark
To run benchmark of your grammar run:
```sh
$ zig build run --release=fast -- benchmark <grammar-file> -i <input-file>
```
Where `<input-file>` contains test-strings on each line.
