This directory contains the results of compilation tests. Specifically, the results are from testing both the from scratch compilation time and relative binary size increases of various features for both the regex and regex-automata crates.

Here's an example of how to run these tests for just the regex crate. You'll need the regex-cli command installed, which can be found in the regex-cli directory in the root of this repository.

This must be run in the root of a checkout of this repository.

$ mkdir /tmp/regex-compile-test
$ regex-cli compile-test ./ /tmp/regex-compile-test | tee record/compile-test/2023-04-19_1.7.3.csv

You can then look at the results using a tool like xsv:

$ xsv table record/compile-test/2023-04-19_1.7.3.csv

Note that the relative binary size is computed by building a "baseline" hello world program, and then subtracting that from the size of a binary that uses the regex crate.
