Polymer PackSquash
PackSquash runner for polymer resource packs!
About this Mod
Polymer PackSquash Integration
This mod integrates PackSquash with Polymer’s resource pack generation to automatically optimize generated resource packs so you don't have to manually compress after changes.
Setup
Get the latest PackSquash release.
Place the binary here:
polymer/packsquashThe mod will automatically create a
packsquash.tomlin thepolymerfolder.
These are the default paths the mod will use. You can adjust them in the configuration file config/polymer-squasher.json
Default config
{
"enabled": true,
"log-packsquash": false,
"log-hash-mismatch": false,
"force-size-based-hash": false,
"cleanup": false,
"ignore-hash-paths": [
"polymer-credits.txt"
],
"packsquash-path": "polymer/packsquash",
"packsquash-toml-path": "polymer/packsquash.toml",
"hash-file-path": "polymer/hashes.json",
"resource-pack-directory": "polymer/pack",
"minified-zip-path": "polymer/resource_pack.min.zip"
}
Config options
- enabled — turn the integration on/off.
- log-packsquash — print PackSquash output to the log.
- log-hash-mismatch — log when a file’s hash changes (useful for debugging).
- packsquash-path — path to the PackSquash binary.
- packsquash-toml-path — path to the PackSquash TOML config file.
- ignore-hash-paths — list of path prefixes to ignore hash mismatches when hashing.
- force-size-based-hash — if
true, the mod will use file size instead of a full hash (faster, less precise) - cleanup - cleans up old files in the cached pack folder
How it works
When enabled, the mod will hash the generated resource pack files. The hashes are written to polymer/hashes.json.
If nothing has changed since the last run, PackSquash is skipped.
If changes are detected, the mod will run PackSquash after Polymer finishes generating the resource pack.
If the process completes successfully, the optimized version is used instead.
