kiss

Tiny and straightforward package manager for KISS written in POSIX sh.

• Less than 1000 lines of POSIX sh (excluding blank lines and comments).
• Runtime dependency detection.
• Incremental package installation.
• Fast dependency solver.
• File conflict detection.
• Package alternatives system.
• 3-way handshake for /etc/ configuration files.
• Binary stripping.
• shellcheck compliant.

Dependencies / Portability

# - Anything with a specification should follow it (POSIX, BSD, etc).
# - Anything without a specification which has ONLY a single (widely used)
#   implementation will be considered portable (git, curl, etc).
#
#   POSIX utilities
#   - sh        (POSIX)
#   - find      (POSIX) -type f, -type d, -exec {} [+;], -o, -print, !
#   - ls        (POSIX) -l, -d
#   - sed       (POSIX) -n, s/<search>/<replace>/g, /<delete>/d
#   - grep      (POSIX) -l, -F, -x, -f, -q, -v
#   - sort      (POSIX) -r, -u, -k
#   - tee       (POSIX) -a
#   - date      (POSIX)
#   - mkdir     (POSIX) -p

#
#   Misc
#   - su*       (sudo, doas, su) (in order, optional)
#   - git       (downloads from git) (must link to curl)
#   - curl      (downloads over http) (also needed by git)
#   - sha256    (multiple fallbacks: sha256sum, shasum, sha256, openssl, etc)
#
#   Compiler/libc utilities (depends cc & libc)
#   - readelf   (optional) (Part of compiler toolchain) (GNU, LLVM or elfutils)
#   - strip     (optional) (Part of compiler toolchain) (GNU, LLVM or elfutils)
#   - ldd       (optional) (Part of libc)
#
#   Tarball compression
#   - tar       (as portable as can be) (merely: cf, tf, xf)
#   - bzip2     (widely used) -d, -z
#   - xz        (widely used) -d, -z, -c, -T

Extending the package manager

The contrib directory contains a set of simple scripts to extend the package manager. These are just simple and stupid automations which parse the package format.

• kiss-chbuild: Spawn a throwaway chroot.
• kiss-chroot: Enter a KISS chroot.
• kiss-depends: Display a package's dependencies.
• kiss-export: Turn an installed package into a KISS tarball.
• kiss-fork: Copy a package's repository files into the current directory.
• kiss-link: Link a repository file to another repository.
• kiss-manifest: Display all files owned by a package.
• kiss-maintainer: Display the package maintainers.
• kiss-new: Create a boilerplate package.
• kiss-orphans: List orphaned packages.
• kiss-outdated: List outdated packages based on Repology versions.
• kiss-owns: Check which package owns a file.
• kiss-reset: Reset the system to the base.
• kiss-revdepends: Display packages which depend on package.
• kiss-size: Show the size on disk for an installed package.
