alpm-pkginfo

A library and commandline toolkit for the specification, writing and parsing of PKGINFO files used in Arch Linux Package Management (ALPM).

PKGINFO files cover a package's metadata and carry various datasets that specify how a package is used in the context of a distribution.

Documentation

• https://alpm.archlinux.page/rustdoc/alpm_pkginfo/ for development version of the crate
• https://docs.rs/alpm-pkginfo/latest/alpm_pkginfo/ for released versions of the crate

Examples

Library

Create a PKGINFO version 2 file:

use std::str::FromStr;
use alpm_pkginfo::PackageInfoV2;
let pkginfo_data = r#"
pkgname = example
pkgbase = example
xdata = pkgtype=pkg
pkgver = 1:1.0.0-1
pkgdesc = A project that does something
url = https://example.org/
builddate = 1729181726
packager = John Doe <john@example.org>
size = 181849963
arch = any
license = GPL-3.0-or-later
license = LGPL-3.0-or-later
replaces = other-package>0.9.0-3
group = package-group
group = other-package-group
conflict = conflicting-package<1.0.0
conflict = other-conflicting-package<1.0.0
provides = some-component
provides = some-other-component=1:1.0.0-1
backup = etc/example/config.toml
backup = etc/example/other-config.txt
depend = glibc
depend = gcc-libs
optdepend = python: for special-python-script.py
optdepend = ruby: for special-ruby-script.rb
makedepend = cmake
makedepend = python-sphinx
checkdepend = extra-test-tool
checkdepend = other-extra-test-tool
"#;
assert!(PackageInfoV2::from_str(pkginfo_data).is_ok());

Create a PKGINFO version 1 file:

use std::str::FromStr;
use alpm_pkginfo::PackageInfoV1;
let pkginfo_data = r#"
pkgname = example
pkgbase = example
pkgver = 1:1.0.0-1
pkgdesc = A project that does something
url = https://example.org/
builddate = 1729181726
packager = John Doe <john@example.org>
size = 181849963
arch = any
license = GPL-3.0-or-later
license = LGPL-3.0-or-later
replaces = other-package>0.9.0-3
group = package-group
group = other-package-group
conflict = conflicting-package<1.0.0
conflict = other-conflicting-package<1.0.0
provides = some-component
provides = some-other-component=1:1.0.0-1
backup = etc/example/config.toml
backup = etc/example/other-config.txt
depend = glibc
depend = gcc-libs
optdepend = python: for special-python-script.py
optdepend = ruby: for special-ruby-script.rb
makedepend = cmake
makedepend = python-sphinx
checkdepend = extra-test-tool
checkdepend = other-extra-test-tool
"#;
assert!(PackageInfoV1::from_str(pkginfo_data).is_ok());

Commandline

  --pkgdesc "A project that does something" \
  --url "https://example.org/" \
  --builddate "1729181726" \
  --packager "John Doe <john@example.org>" \
  --size "181849963" \
  --arch "any" \
  --license "GPL-3.0-or-later" \
  --license "LGPL-3.0-or-later" \
  --replaces "other-package>0.9.0-3" \
  --group "package-group" \
  --group "other-package-group" \
  --conflict "conflicting-package<1.0.0" \
  --conflict "other-conflicting-package<1.0.0" \
  --provides "some-component" \
  --provides "some-other-component=1:1.0.0-1" \
  --backup "etc/example/config.toml" \
  --backup "etc/example/other-config.txt" \
  --depend "glibc" \
  --depend "gcc-libs" \
  --optdepend "python: for special-python-script.py" \
  --optdepend "ruby: for special-ruby-script.rb" \
  --makedepend "cmake" \
  --makedepend "python-sphinx" \
  --checkdepend "extra-test-tool" \
  --checkdepend "other-extra-test-tool"

All options for alpm-pkginfo can also be provided as environment variables. The following is equivalent to the above:

PKGINFO_PKGNAME="example" \
PKGINFO_PKGBASE="example" \
PKGINFO_XDATA="pkgtype=pkg" \
PKGINFO_PKGVER="1:1.0.0-1" \
PKGINFO_PKGDESC="A project that does something" \
PKGINFO_URL="https://example.org/" \
PKGINFO_BUILDDATE="1729181726" \
PKGINFO_PACKAGER="John Doe <john@example.org>" \
PKGINFO_SIZE="181849963" \
PKGINFO_ARCH="any" \
PKGINFO_LICENSE="GPL-3.0-or-later LGPL-3.0-or-later" \
PKGINFO_REPLACES="other-package>0.9.0-3" \
PKGINFO_GROUP="package-group other-package-group" \
PKGINFO_CONFLICT="conflicting-package<1.0.0 other-conflicting-package<1.0.0" \
PKGINFO_PROVIDES="some-component some-other-component=1:1.0.0-1" \

alpm-pkginfo create v2

Features

• cli adds the commandline handling needed for the almp-pkginfo binary (enabled by default).
• winnow-debug enables the winnow/debug feature, which shows the exact parsing process of winnow.
