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.
