Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

parse

✓ from dparse2 import parse

Original dparse used 'from dparse import parse'. The module is now dparse2.

filetypes

✓ from dparse2.filetypes import RequirementsFile

✗ from dparse import filetypes

Package name changed from dparse to dparse2.

dparse2

✓ import dparse2

Top-level package is dparse2, not dparse.

Parses a requirements.txt file and prints each dependency name and version specifier.

from dparse2 import parse from dparse2.filetypes import RequirementsFile with open('requirements.txt') as f: content = f.read() parsed = parse(content, RequirementsFile) for dep in parsed.dependencies: print(dep.name, dep.specs)

Debug

Known issues

breakingPackage renamed from dparse to dparse2. All imports must use dparse2.

fix

Replace 'import dparse' with 'import dparse2'.

affects: all

breakingPython 2.7 support dropped after 0.5.0.1. Versions 0.6+ require Python 3.6+.

fix

Upgrade to Python 3.6+ or use dparse2==0.5.0.1.

affects: >=0.6.0

gotchaparse() returns a ParsedFile object; dependencies can be empty if file is malformed. Always check dependencies before iteration.

fix

Use 'if parsed.dependencies: for dep in parsed.dependencies: ...'

affects: all

gotchaRequirementsFile parser expects base directory (default: '.'). Relative paths in requirements.txt are resolved against the base dir.

fix

Pass base_dir parameter to parse() to control relative path resolution.

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'dparse'

Package renamed to dparse2; old import fails.

fix

Run 'pip install dparse2' and change imports to 'import dparse2'.

AttributeError: module 'dparse2' has no attribute 'parse'

Wrong import path; parse is a function, not a module attribute when using 'import dparse2'.

fix

Use 'from dparse2 import parse' or 'dparse2.parse(...)'.

TypeError: parse() missing 1 required positional argument: 'file_type'

parse() requires a file type class as second argument.

fix

Provide a file type, e.g., 'from dparse2.filetypes import RequirementsFile' and call 'parse(content, RequirementsFile)'.
