From 4ecd13be3f2a744ef6ea0fe6ef9155e8614c72b3 Mon Sep 17 00:00:00 2001 From: andev0x Date: Fri, 16 Jan 2026 01:07:32 +0700 Subject: [PATCH] feat(suggestion): add offline intelligent commit message engine Introduce an offline commit message suggestion engine that analyzes git diffs to generate context-aware commit messages without AI or internet access. Key features: - Deep git diff analysis to detect code structures and change patterns - Context-aware template scoring based on file type and detected intent - Multi-file pattern detection for features, bug fixes, and refactors - Intelligent scope detection from changed paths - Expanded template library with 100+ variants and new types (security, perf, style) Docs: - Add optimization details, quickstart, and template reference --- .gitignore | 1 + docs/OPTIMIZATION.md | 327 +++++++++++++++++++ docs/OPTIMIZATION_SUMMARY.md | 196 ++++++++++++ docs/QUICKSTART.md | 314 ++++++++++++++++++ docs/TEMPLATE_REFERENCE.md | 258 +++++++++++++++ internal/analyzer/analyzer.go | 509 ++++++++++++++++++++++++++++-- internal/templater/templater.go | 94 +++++- internal/templater/templates.json | 225 ++++++++++++- 8 files changed, 1880 insertions(+), 44 deletions(-) create mode 100644 docs/OPTIMIZATION.md create mode 100644 docs/OPTIMIZATION_SUMMARY.md create mode 100644 docs/QUICKSTART.md create mode 100644 docs/TEMPLATE_REFERENCE.md diff --git a/.gitignore b/.gitignore index 19101ed..c269ff6 100644 --- a/.gitignore +++ b/.gitignore @@ -37,6 +37,7 @@ Thumbs.db gitmit dist/ build/ +/bin/ # Env .env diff --git a/docs/OPTIMIZATION.md b/docs/OPTIMIZATION.md new file mode 100644 index 0000000..fafa91c --- /dev/null +++ b/docs/OPTIMIZATION.md @@ -0,0 +1,327 @@ +# Gitmit Optimization Guide + +## Overview + +This document describes the intelligent optimizations implemented in Gitmit to provide smart, context-aware commit message suggestions based purely on git changes analysis and template matching - all working locally without any internet connection or AI. + +## Key Optimizations + +### 1.

Context-Aware Template Scoring + +Templates are now scored based on multiple factors: + +#### Scoring Criteria +- **Base Score**: 1.0 for all templates +- **Pattern Matching**: +2.0 for templates matching detected patterns +- **Structure Detection**: +1.5 for using detected functions/structs +- **Purpose Relevance**: +1.0 for meaningful purpose placeholders +- **File Type Context**: +0.5-1.5 based on file extensions +- **Major Changes**: +1.0 for restructure/refactor templates +- **Generic Penalty**: -0.5 for generic templates when specific info exists + +#### Template Selection Process +1. Score all available templates +2. Sort by score (highest first) +3. Select highest-scored template not in recent history +4. Fall back to highest-scored if all are recent duplicates + +### 3. Enhanced Template Library + +The template library has been expanded with: + +#### New Categories +- `handler`: For request handler changes +- `middleware`: For middleware modifications +- `service`: For service layer changes +- `util`: For utility functions +- `parser`: For parsing logic +- `analyzer`: For analysis code + +#### New Action Types +- `SECURITY`: Security-focused commits +- `PERF`: Performance improvements +- `STYLE`: Code formatting changes +- `TEST`: Test modifications + +#### More Variations +Each category now includes 3-6 template variations for better context matching. + +### 4. Multi-File Pattern Detection + +The system now analyzes patterns across multiple files: + +#### Detected Patterns +- **feature-addition**: 3+ new files (60% of changes) +- **bug-fix-cascade**: 3+ modifications with "fix" keywords +- **refactor-sweep**: Mix of additions, modifications, and deletions (4+ files) +- **test-suite-update**: 70%+ test files changed +- **config-update**: 70%+ config files changed +- **api-redesign**: 3+ API/handler files modified +- **database-migration**: 2+ migration/schema files changed + +#### Automatic Adjustments +When multi-file patterns are detected, the system automatically: +- Adjusts commit action type +- Updates purpose description +- Improves message context + +### 5.
