The main constituent of this repository is an R Markdown document, regex-performance.Rmd, which when rendered will run the benchmark and plot the results. The document explains its methodology and describes the output. The rendered document will look like this example.
To run the benchmark you can either load regex-performance.Rmd into RStudio and click on "Knit HTML", or run make from a (Unix) command line. You'll need the rmarkdown package installed in the latter case. You can also manually render the document using rmarkdown::render("regex-performance.Rmd").
Contributions to the document are welcome, as are contributions of output from different systems. Please create a pull request for either of these. Results should be created with a suitably descriptive filename within the results subdirectory.
