A Python script minifier, named after Thread Snakes which are small family of snakes.
Bit experimental, and can break code. If you can fix some cases, do file an issue / pr if you can fix it.
python3 threadsnake [options] file [files....]
There are the following output options:
--no-compress- Don't run compression on the code--no-rename- Disables variable renaming, which can break code in some cases.
No external dependencies, just pure python3. Might need a more modern verison, as this was developed using 3.11.
To avoid breakage:
- Remember, this merges files in one global namespace. Don't reuse global variable names across files, unless you intend for that.
- As variables get renamed, your use of
eval()/exec()can break. - Import across files in the form "from OTHERFILE import dep1, dep2, ...".
import xgets removed if its a known other module, so to allow your code to be ran without being minified, do this pattern. - Renaming will cause issues when you pass an instance of a class from another file to a function.
- Cleaning up imports into a single line.
- Deduplication of imports.
- Removal of doc strings
- Comment removal (part of the AST translation process)
- Patched unparse() removing unnessary space.
- Compresses the code, converts to base85 and packs in a wrapper script to decompress and run.
- Cleaning up variable/function/class names
- Better modifications in unparse() - merging statements into one line.
- Better namespacing, to break code in less cases.
