scratchpkg

A package manager for Venom Linux.

Description

Scratchpkg is a package manager built in order to manage packages for Venom Linux. This package manager is fully written in shell script POSIX. The package building script uses the port system like in Arch's makepkg and CRUX's pkgmk. Packages are built and installed into a temporary location using DESTDIR method and are afterwards compressed in a file directory using tar xz by default.

Installing the packaged tar means it is extracted into real system. After that all files extracted is recorded into an index directory. So scratchpkg will track all installed files. Scratchpkg can automatically resolve dependencies order. Scratchpkg reads the build script (spkgbuild) in the ports directory in order to get all necessary variables and functions before building them.

spkgbuild

spkgbuild is build script sourced by pkgbuild to build the package. The example of spkgbuild as follows:

# description	: This is example package
# homepage	: https://example.com/
# maintainer	: Emmett1, emmett1 dot 2miligrams at gmail dot com
# depends	: package1 package2 package3
name=foobar
version=1.0.0
release=1
backup="etc/example.conf etc/foobar.conf"
noextract="foobar.tar.xz"
source="https://dl.example.com/foobar.tar.xz
 $name-$version.tar.gz::https://github.com/archive/$version.tar.gz
 example.conf"
nostrip="lib.*/ld-.*\.so$
 lib.*/libc-.*\.so$
 lib.*/libpthread-.*\.so$
 lib.*/libthread_db-.*\.so$"
 
build() {
 cd $name-$version
 
 ./configure --prefix=/usr
 make
 make DESTDIR=$PKG install
 
 install -d $SRC/example.conf $PKG/etc/example.conf
}

Note: When create new package, its recommended to build using fakeroot first to make sure the build script is not broken and leave untracked file inside system.

spkgbuild format:

• description: Short description for package.
• homepage: Url for software webpage
• maintainer: maintainer name and email
• depends: All required dependencies, separate with space.
• name: Package name, need same as port directory's name.
• version: Package's version.
• release: Package's release version, useful when build script need change with same package version.
• backup: File need backup when upgrading package (without leading with '/').
• noextract: Specify file no need to extract, separate with space.
• source: Package's source urls, separate with space, can use as <new-source-name>::<source-url> to save source file with different name (see spkgbuild example).

Package options

This options is set in /etc/scratchpkg.conf for global options, default values are commented on:

# SOURCE_DIR="/var/cache/scratchpkg/sources"
# PACKAGE_DIR="/var/cache/scratchpkg/packages"
# WORK_DIR="/var/cache/scratchpkg/work"
# CURL_OPTS=""
# COMPRESSION_MODE="xz"
# NO_STRIP="no"
# IGNORE_CHECKSUM="no"
# KEEP_LIBTOOL="no"
# KEEP_LOCALE="no"
# KEEP_DOC="no"
# NOCOLOR="no"

pkgadd

pkgadd is a tool to install and upgrade package created by pkgbuild. Install package is simply extract <name>-<version>-<release>.spkg.xz by using tar into real system then save list extracted file into package PKGDB_DIR. Upgrading package is also using same extract as install, it will replace old files then compare list file from old and new package and remove old file which not exist in new package (like Slackware pkgtool does).

Usage:
 pkgadd [ <options> <package.spkg.txz> ]
Options:
 -u, --upgrade upgrade package
 -r, --reinstall reinstall package
 -c, --ignore-conflict ignore conflict when installing package
 -v, --verbose print files installed
 -h, --help show this help message
 --no-backup skip backup when upgrading package
 --print-dbdir print package database path
 --root=<path> install to custom root directory
Example:
 pkgadd foobar-1.0-1.spkg.txz -uc --no-backup upgrade package foobar-1.0-1 without backup its 
 old configuration files and skip conflict check

pkgbuild

pkgbuild is a tool to build package from ports. Is will source spkgbuild to get build information before creating package. Package is created into <name>-<version>-<release>.spkg.xz format. To build package, you need cd into port directory before run pkgbuild command.

Usage:
 pkgbuild [ <options> <arguments> ]
Options:
 -q --quiet show only status messages and errors
 -i, --install install package into system
 -u, --upgrade upgrade package
 -r, --reinstall reinstall package
 -c, --ignore-conflict ignore conflict when installing package
 -v, --verbose verbose install process
 -f, --force-rebuild rebuild package
 -m, --skip-checksum skip checksum checking
 -g, --genchecksum generate checksum
 -o, --download download only source file
 -x, --extract extract only source file
 -p, --pkgfiles generate list files in package
 -w, --keep-work keep working directory
 -h, --help show this help message
 -C, --clean remove downloaded sources and prebuilt packages
 --config=<config> use custom config file
 --srcdir=<path> override directory path for sources
 --pkgdir=<path> override directory path for compiled package
 --workdir=<path> override directory path for working dir
 --no-backup skip backup configuration file when upgrading package
Example:
 pkgbuild -iw this will build, install package and keep working directory
Note:
 * use pkgbuild without any options will only download source and build package by using other default options
 * pkgbuild need run inside port directory

pkgdel

pkgdel is a tool to remove package from system. It will read file listed in package PKGDB_DIR and remove it.

Usage:
 pkgdel [ <options> <package name> ]
Options:
 -h, --help show this help message
 -v, --verbose print removed files
 --root=<path> remove package from custom root directory
Example:
 pkgdel firefox -v --no-preremove remove package firefox, print deleted files and skip pre-remove script

pkgrebuild

pkgrebuild is a script to rebuild base packages in right toolchain order.

 Usage:
 pkgrebuild <options>
 
 Options:
 -t, --toolchain rebuild toolchain	
 -b, --base rebuild base
 -h, --help Show this help
 
 Example:
 pkgrebuild rebuild toolchain and base ports, in this order
 pkgrebuild -t rebuild toolchain ports only
 pkgbrebuid -b rebuild base ports only

pkgbase

pkgbase is a script to remove all packages other than base and any user input.

 Usage:
 pkgbase <options>

Extra tools

Extra tools is some scripts come with scratchpkg to help users do things more easier. More extra scripts may added from time to time.

• xchroot: chroot script.

   Usage: 
   xchroot <chroot-dir> [command]. 
   Example: 
   xchroot /mnt/venom /bin/bash
  

• portcreate: script to create template port.

• updateconf: script to update configuration files (*.spkgnew).

• revdep: A reverse dependency script (like in Gentoo and CRUX, but my version), need to run after upgrade and remove package to check broken package(s). Specify package name if want to check single package only.

   Usage:
   revdep [option] [arg]

   -h, --help print this help message
  

pre-install.sh and post-install.sh scripts

A pre-install.sh script is a shell script containing commands that need to run before installing or upgrading a package. This script needs to placed in the port directory and later will be included in tar-ed package. It is only executed when installing or upgrading though scratch.

Example of pre-install.sh script for ffmpeg:

#!/bin/sh
 printf '%s\n' "Optional dependencies:
 libva - For hardware accelerated video processing
 libvdpau - For hardware accelerated video processing(mostly for nvidia)"# package install script

The post-install.sh script functions in a similar way and runs after installing or upgrading a package.

/etc/scratchpkg.repo

/etc/scratchpkg.repo is file to define repo directory and url to sync/update port's. This is example default /etc/scratchpkg.repo;

# /etc/scratchpkg.repo : scratchpkg repo file
#
# format:
# <repo directory> <repo url> <repo branch, "main" by default>
#
/usr/ports/main		 https://gitlab.com/venomlinux/ports/main
#/usr/ports/community	https://gitlab.com/venomlinux/ports/community
#/usr/ports/kde 	https://gitlab.com/venomlinux/ports/kde
#/usr/ports/mate	 https://gitlab.com/venomlinux/ports/mate
#/usr/ports/xfce	 https://gitlab.com/venomlinux/ports/xfce
#/usr/ports/multilib	https://gitlab.com/venomlinux/ports/multilib
#/usr/ports/nonfree	 https://gitlab.com/venomlinux/ports/nonfree
#/usr/ports/testing	 https://gitlab.com/venomlinux/ports/testing

Note: url is optional. Add if need to sync it.

Install

Installing is performed by just simply execute/running the file INSTALL.sh:

./INSTALL.sh

If packaging, append DESTDIR=/tmp/path in front of your command:

DESTDIR=/tmp/path ./INSTALL.sh
