history
Project history and usage
pacparser is a portable C library, Python module, and command-line toolset for parsing and testing Proxy Auto-Config files.
Project history
Manu Garg developed pacparser to make Proxy Auto-Config parsing easy to embed in other programs. The implementation evaluates PAC JavaScript and supplies the additional helper functions expected by PAC files.
The current official README says pacparser embeds QuickJS. Its API remains available through C and Python interfaces alongside the pactester CLI.
Adoption history
The official README reports support for Linux, FreeBSD, macOS, and Windows, and distributes the project as a C shared library, Python module, and pactester command-line utility. The input package metadata also records packaging across Homebrew, Debian/Ubuntu, Alpine, MacPorts, Nix, Arch, and Scoop.
How it is used
Applications initialize the parser, load a PAC file or string, and query which proxy should handle a URL and host. Administrators and developers can use pactester to exercise PAC behavior from the command line.
The official README warns that parser state is process-global and the API is not thread-safe; multithreaded consumers must serialize calls.
Why package nerds care
pacparser gives programs a reusable implementation of browser-style PAC evaluation rather than requiring each consumer to embed and reproduce PAC JavaScript helper behavior. It is useful for testing PAC rules independently with pactester and for adding PAC awareness to C or Python software.
Timeline
- Current generation: The official README documents QuickJS as the embedded JavaScript engine.
- Current distribution: Prebuilt Python packages cover Linux, Windows, Intel macOS, and Apple-silicon macOS.
Related projects
- QuickJS provides the embedded JavaScript engine in the current implementation. Mozilla's PAC implementation supplied the basis for standard PAC helper functions.
