pkgbuild_parser

Documentation in Spanish

Introduction

pkgbuild_parser is a module written in Python (compatible with Python 3.x) designed to extract information from a PKGBUILD. The main purpose of this module is to provide simple and direct access to the most important fields of a PKGBUILD without relying on external tools or additional libraries.

• Version: 2.1.0
• License: MPL-2.0 2026 KevinCrrl
• Dependencies: None
• Style: Simplicity, no external dependencies, easy to use

This module allows you to quickly and directly obtain data such as package name, version, description, license, URL, and source file.

Main functions for the user

Although the module internally has support functions (get_base), the user only needs to use the high-level functions, which are clear and direct:

Note: The internal functions (get_base, multiline, replacevar, processvar and remove_quotes) are intended for module use and do not need to be used by the user, except when you want to create functions that are not in the parser.

Also, you can use the InfoDict class to create dictionariess from selected information, InfoDict has this methods:

Installation and use

Option 1: AUR

The module is available on the AUR as python-pkgbuild-parser.

Option 2: PyPi

pip install pkgbuild-parser

Basic usage

Error handling

If the PKGBUILD file does not exist, a ParserFileError is raised, which must be caught to prevent the program from failing.

A ParserKeyError can also be raised if getting a value from the PKGBUILD fails, for example, if the license is not declared correctly, and get_license() is called, this exception will be raised.

Limitations and additional notes

• Starting with version 1.2.0, the parser can replace known variables in a Bash string. For example, if you try to fetch a source file and it is declared in the PKGBUILD as "${url}/package-$pkgver.tar.gz", pkgbuild-parser will be able to recognize these variables, retrieve them, and replace them with their values.
• The module's goal is to extract only basic information from standard PKGBUILDs, It cannot replace variables it does not recognize, such as "$my_personal_var", or variations of known variables, such as "$pkgname%suffix".
• It works best with PKGBUILDs that follow the Arch Wiki standards.
• This code doesn't implement a proper parser; it simply reads the PKGBUILD file and extracts the necessary information using various conditions and state logic. However, I try to make it as accurate as possible :)
• Since version 0.4.0, the module can extract information from arrays or lists, such as depends, makedepends, source, optdepends, license, options, and checkdepends.
• Since version 1.0.0, functions that return a string no longer include quotes by default.
