A tool to compare different regexp libraries in Go.
- Build docker image first:
docker build -t regexcmp .
- Run:
# To benchmark all libs with 100MB payload
docker run -it regexcmp 1000000
# To benchmark specific lib
docker run -it regexcmp 1000000 rure
# Use help to see additional arguments
docker run -it regexcmp -h- Example output:
