fix(gitea): remove invalid import statement from function body
Removed the incorrectly placed `import difflib` line from inside the _apply_unified_diff() method. The module is now imported at the top of the file where it belongs. Refs: #11

title: Gitea Coder - Workflow Role with Scope Enforcement
|
||||
author: Jeff Smith + Claude + minimax
|
||||
version: 1.0.1
|

license: MIT
|
||||
description: High-level workflow role for LLM-based code generation with scope gating and quality gates
|
||||
requirements: pydantic, httpx
|
||||
changelog:
|
||||
1.0.1:
|
||||
- Fixed: moved difflib import to module level (was incorrectly inside function)
|
||||
- difflib is Python stdlib, no pip install required
|
||||
1.0.0:
|
||||
- Initial implementation of gitea_coder role
|
||||
- Branch creation with scope gating (prevents main pushes)
|
||||
- Enforces branch naming conventions (feature/, fix/, refactor/, etc.)
|
||||
- Generates detailed commit messages with ticket references
|
||||
- Creates PRs from branches
|
||||
- Reads ticket requirements from issues
|
||||
- Unified file operations workflow
|
||||
- Added diff-based updates with apply_diff()
|
||||
- Added size delta gating in commit_changes() for quality control
