But it contains tools used at the wrong places results in very inperformant parsers. This project aims to deliver some statistic identifiying those hotspots of a parser.\n\nThe tool uses *AspectJ* to link into an existing parser. The logging possibilities of JavaCC are not used.\n\nSome statistics were delivered combining some values of a real parsing process. Mainly you are able to identify the productions with the most complex lookahead. *Excessive lookaheads are one of the main reasons to produce poor parser performance.*\n\n## Example JSqlParser\n\nThe motivation developing this project were some very inperformant parsing processes of JSqlParser. \n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjsqlparser%2Fjavacc-perf-diag","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjsqlparser%2Fjavacc-perf-diag","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjsqlparser%2Fjavacc-perf-diag/lists"}
