This is an alternative package system I am experimenting with. Instead of the usual `PKGBUILD`, `APKBUILD`, `xbps-template` and `Pkgfile` format, this repository explores a more unixy approach.
Each Package is split into multiple files.
```sh
zlib/ # Package name.
├─ build # Build script.
├─ depends # Dependencies (one per line).
├─ sources # Sources (one per line).
├─ version # Package version.
┘
# Files generated by the package manager.
├─ manifest # The built package's files and directories.
├─ checksums # The checksums for the source files.
┘
# Optional files.
├─ post_install # The script to run after install.
When a built package is installed, this entire directory tree is copied to `/var/db/puke` where it becomes a database entry. Listing the dependencies for a package is a simple as printing the contents of the `depends` file. Searching for which package owns a file is as simple as checking each `manifest` file.
This new structure also allows the package manager to be stupid simple. POSIX `sh` has no arrays. However, they are mimicked by looping over each line of each file. No more insecure `depends="pkg pkg pkg"` and `for pkg in $depends`.
The `build` file should contain the necessary steps to patch, configure, build and install the package. When at the install step; the variable `$pkg_dir` is available. This variable points to the directory the package manager uses for built packages. Whatever is in this directory will become part of the package's manifest and will be copied to `/` (or `$PUKE_ROOT`).
The `manifest` file contains the built package's file and directory list. The full paths to files are listed first and the directories (*in reverse*) follow. This allows the package manager to remove the directories if they're empty without needing checks in-between.
The `version` file contains the package's version as well as its release number. The format of this file is `version release`. The `release` portion allows a package upgrade without the modification of the version number.
Puke is a simple package manager written in POSIX `sh`. The package manager does not need to be added to your `PATH`. Instead it runs inside the packages repository, very similar to Void Linux's `xbps-src`.
