## TexSoup Validation

`pymini` has been validated against the upstream `TexSoup` test suite in package mode.
Current validation: raw source code `68.2%` smaller, compressed source code
(`.tar.gz`) `36.1%` smaller.
<!-- Raw bytes: 98,181 -> 31,212. Compressed bytes: 70,532 -> 45,054. -->

| Measurement | Original | Minified | Reduction | Reduction Rate |
| --- | ---: | ---: | ---: | ---: |
| Raw Python source (`*.py`) | `98,181` bytes | `31,212` bytes | `66,969` bytes | `68.2%` |
| `.tar.gz` of `TexSoup/` | `70,532` bytes | `45,054` bytes | `25,478` bytes | `36.1%` |

To reproduce that flow locally:

```bash
git clone https://github.com/alvinwan/TexSoup /tmp/texsoup
mkdir -p /tmp/texsoup-out/TexSoup
pymini package /tmp/texsoup/TexSoup -o /tmp/texsoup-out/TexSoup
cp -R /tmp/texsoup/tests /tmp/texsoup-tests
PYTHONPATH=/tmp/texsoup-out:/tmp/texsoup-tests python3 -m pytest /tmp/texsoup-tests/tests -o addopts=''
```

To compare raw package bytes before and after minification:

```bash
rg --files /tmp/texsoup/TexSoup -g '*.py' | xargs cat | wc -c
rg --files /tmp/texsoup-out/TexSoup -g '*.py' | xargs cat | wc -c
```

To compare compressed package snapshots:

```bash
tar -czf /tmp/texsoup-original-package.tar.gz -C /tmp/texsoup TexSoup
tar -czf /tmp/texsoup-minified-package.tar.gz -C /tmp/texsoup-out TexSoup
stat -f%z /tmp/texsoup-original-package.tar.gz
stat -f%z /tmp/texsoup-minified-package.tar.gz
```
