cabal-file-parser 0.1.0

Zero-dependency parser for Haskell .cabal files: top-level fields, build stanzas (library/executable/test-suite) and build-depends as clean package names.

cabal-file-parser

A tiny, dependency-free Python parser for Haskell .cabal package files. It reads the top-level fields (name, version, license, …) and the build stanzas (library, executable NAME, test-suite NAME, benchmark NAME, common), and turns build-depends into a clean list of package names — handy for CI, dashboards, dependency audits and metadata tooling.

Install

pip install cabal-file-parser

CLI

cabal-file-parser mypackage.cabal

Prints a JSON summary: name, version, all fields, every stanza, and a de-duplicated all_dependencies list.

Library

from cabal_file_parser import parse_cabal, dependency_names

pkg = parse_cabal(open("mypackage.cabal").read())
print(pkg.name, pkg.version)
for s in pkg.stanzas:
    print(s.kind, s.name, dependency_names(s.fields.get("build-depends", "")))

dependency_names("base >=4.7 && <5, text") → ["base", "text"].

A pragmatic parser for tooling/metadata, not a full Cabal grammar.
