Rusty ECMA Benches

This project is used to generate benchmarks for using both RESS and RESSA to parse some popular JS libraries.

build.rs

The build.rs file here uses the handlebars templating engine to generate a bunch of files in the src/bin directory. Nearly all of the JS libraries used here provide both a "normal" and minified version, some also provide an es modules version, two binaries is generated for each of these provided files one for benching ress and one for benching ressa, that is up to 6 benchmarks per JS library.

The primary reason these are created as independent binaries is to utilize the include_str! macro as apposed to using any kind of IO to read the javascript. This way the benchmarks are more about the time it takes to parse each file.

scripts

check_tags.js

This file is setup to query the current tags for both ress and ressa, if those have been added to the cargo.toml file here is updated to point to the most recent tag.

compile_all.sh

This file iterates through the files created in src/bin and compiles each binary with the --release flag and then pulls that out of the target/release folder and puts it in /bins this is really just to make things easier for the script run_all.sh.

post_run.js

This script will iterate through all of the results in a single run and insert them into a sqlite database.

run_all.sh

This actually performs the benchmarks for each file in bins using hyperfine placing the results into the folder results/<result-date>[-run-number] and then executes the post_run.js script.
