Thus, with only a single token of\nlookahead, we are able to evaluate an arbitrary expression with correct rules of\nprecedence.\n\n## Usage\n\nRunning the program will show the parse tree and result for the input.\n\n```bash\ncargo run\n```\n\nType in the input, and hit return.\n\n## Run tests\n\nTo run all tests, run\n\n```bash\ncargo test\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnathom%2Fexpr-parser","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnathom%2Fexpr-parser","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnathom%2Fexpr-parser/lists"}
