alpm-repo-db

A library and command line interface for creation and access of alpm-repo-db files (Arch Linux Package Management (ALPM) repository sync databases) and handling of their alpm-repo-desc and alpm-repo-files file formats.

Documentation

• https://alpm.archlinux.page/rustdoc/alpm_repo_db/ for development version of the crate.
• https://docs.rs/alpm-repo-db/latest/alpm_repo_db/ for released version of the crate.

Overview

The alpm-repo-db crate contains a desc module, which provides functionality for writing and parsing of alpm-repo-desc files. These desc files describe the metadata of single packages in an alpm-repo-db (aka. ALPM repository sync databases). They contain data such as the package name, version, architecture, file name, checksums, and dependencies.

It also contains a files module, which provides functionality for writing and parsing of alpm-repo-files files.

This crate provides the command line interfaces (CLI) alpm-repo-desc and alpm-repo-files, which can be used to create, parse, format and validate their respective file formats.

Working with alpm-repo-files

use std::{path::PathBuf, str::FromStr};

use alpm_repo_db::files::{RepoFiles, RepoFilesV1};

# fn main() -> testresult::TestResult {
let data = r#"%FILES%
usr/
usr/bin/
usr/bin/foo
"#;
let paths = vec![
  PathBuf::from("usr/"),
  PathBuf::from("usr/bin/"),
  PathBuf::from("usr/bin/foo"),
];

// Create a RepoFiles from a string.
let files_from_str = RepoFiles::V1(RepoFilesV1::from_str(data)?);

// Create a RepoFiles from list of paths.
let files_from_paths = RepoFiles::V1(RepoFilesV1::try_from(paths)?);

assert_eq!(files_from_str.as_ref(), files_from_paths.as_ref());
# Ok(())
# }

Command line

alpm-repo-desc

Create a repository desc file from CLI arguments:

alpm-repo-desc create v2 \
    --file-name example-1.0.0-1-any.pkg.tar.zst \
    --name example \
    --base example \
    --version 1.0.0-1 \
    --description "An example meta package" \
    --csize 4634 \
    --isize 0 \
    --sha256sum b5bb9d8014a0f9b1d61e21e796d78dccdf1352f23cd32812f4850b878ae4944c \
    --url https://example.org/ \
    --license GPL-3.0-or-later \
    --arch any \
    --builddate 1729181726 \
    --packager "Foobar McFooface <foobar@mcfooface.org>" \
    --depends libfoo \
    --optdepends "libbar: Optional dependency with description" \
    "$REPODESC"

Format repo desc data as JSON:

alpm-repo-desc format "$REPODESC" --output-format json --pretty > "$REPODESC_JSON"

alpm-repo-files

# Create an alpm-repo-files file from an input directory.
alpm-repo-files create path/to/input/dir

# Format an alpm-repo-files file as JSON.
alpm-repo-files format --input-file path/to/repo.files --pretty

# Validate an alpm-repo-files file.
alpm-repo-files validate --input-file path/to/repo.files

Features

• cli: adds dependencies required for the alpm-repo-desc and alpm-repo-files command line interfaces.
• _winnow-debug: enables the winnow/debug feature for step-by-step parser debugging.
