5 | | -`Summary` is a powerful command-line tool that recursively scans directories for |
6 | | -Git repositories and generates concise summaries of the changes within them. It |
7 | | -intelligently creates diffs between tags or, for untagged repositories, between |
8 | | -the first and last commits. |
| 5 | +`Summary` is a blazingly fast, concurrent tool for generating comprehensive |
| 6 | +change summaries across multiple Git repositories. It automatically analyzes tag |
| 7 | +history and produces clean diffs between releases or from commit to commit. |
9 | 8 |
|
10 | | -It's designed for developers who want a quick overview of progress across |
11 | | -multiple projects, helping to generate release notes, track changes, or analyze |
12 | | -development history efficiently. |
| 9 | +Built for developers who need to understand project evolution at scale, |
| 10 | +`Summary` leverages Rust's async runtime and parallel processing to scan |
| 11 | +hundreds of repositories in seconds. |

|
19 | | -### Key Functionality |
20 | | - |
21 | | -`Summary` operates with the following logic: |
22 | | - |
23 | | -1. **Repository Discovery:** It walks the specified directory tree (defaulting |
24 | | - to the current location) and identifies all Git repositories by looking for |
25 | | - `.git` folders. |
26 | | -2. **Tag Analysis:** For each repository, it inspects the existing tags and |
27 | | - sorts them chronologically. |
28 | | -3. **Diff Generation:** |
29 | | - - **If tags are present:** It generates a diff for each period between |
30 | | - consecutive tags (e.g., `v1.0.0` -> `v1.1.0`). It also creates a summary |
31 | | - from the latest tag to the current `HEAD`. |
32 | | - - **If no tags exist:** It generates a single, comprehensive diff from the |
33 | | - very first commit to the final commit in the repository. |
34 | | -4. **Intelligent Filtering:** It automatically excludes numerous binary file |
35 | | - types from the diffs and allows for custom exclusion of directories and file |
36 | | - patterns. |
37 | | -5. **Grouped Output:** The final output groups all changes by their respective |
38 | | - repository and commit/tag range, providing a clean, organized report. |
39 | | - |
40 | | -## ✨ Features |
41 | | - |
42 | | -- **Recursive Git Repository Discovery:** Automatically find and analyze all |
43 | | - repositories within a given path. |
44 | | -- **Automatic Change Summarization:** Generates diffs between consecutive tags |
45 | | - and from the last tag to `HEAD`. |
46 | | -- **Parallel Processing:** Utilizes multiple CPU cores to analyze repositories |
47 | | - in parallel for maximum speed (`-P` flag). |
48 | | -- **Flexible Directory Filtering:** Exclude specific directories like |
49 | | - `node_modules` or `target` from the initial scan. |
50 | | -- **Regex-Based File Omission:** Use regular expressions to omit certain files |
51 | | - (e.g., `*.md`, `CHANGELOG.md`) from the diff generation. |
52 | | -- **Smart Binary Exclusion:** By default, ignores common binary file extensions |
53 | | - (`.png`, `.zip`, `.exe`, etc.) to keep summaries focused on source code. |
54 | | -- **Cross-Platform:** Built with Rust, it runs on Windows, macOS, and Linux. |

56 | | -## 🚀 Installation |
57 | | - |
58 | | -You can install `Summary` directly from `crates.io` using `cargo`. |
| 15 | +## Key Features 🔐 |
59 | 16 |
|
60 | | -```sh |
61 | | -cargo install psummary |
62 | | -``` |
| 17 | +- **Blazing Fast**: Parallel repository scanning and async diff generation |
| 18 | + dramatically outperform manual git operations across multiple projects. |
| 19 | +- **Intelligent Tag Analysis**: Automatically sorts tags chronologically and |
| 20 | + generates diffs between consecutive releases, plus latest tag to HEAD. |
| 21 | +- **Smart Binary Filtering**: Excludes 50+ binary file types by default to keep |
| 22 | + summaries focused on meaningful source code changes. |
| 23 | +- **Regex-Powered Omission**: Fine-tune output with custom regex patterns to |
| 24 | + exclude specific files or directories from diffs. |
| 25 | +- **Concurrent by Default**: Uses `tokio` and `rayon` to maximize CPU and I/O |
| 26 | + throughput across all discovered repositories. |
| 27 | +- **Cross-Platform**: Native performance on Windows, macOS, and Linux. |

104 | | -### Option Details |
| 72 | +Usage: psummary [OPTIONS] |
105 | 73 |
|
106 | | -- `--Parallel` or `-P`: Enables multi-threaded processing. This is highly |
107 | | - recommended when scanning a directory with many repositories. |
108 | | -- `--Root` or `-R`: Specifies the starting directory for the scan. If not |
109 | | - provided, it defaults to the current working directory. |
110 | | -- `--Exclude` or `-E`: Prevents the tool from scanning any directory whose path |
111 | | - contains one of the specified strings. The default value is `node_modules`. To |
112 | | - exclude multiple directories, wrap them in quotes: |
113 | | - `-E "node_modules target dist"`. |
114 | | -- `--Omit` or `-O`: This powerful option uses regular expressions to filter out |
115 | | - files _from the diff summary_. It can be specified multiple times. For |
116 | | - example, to ignore all Markdown and text files, you would use |
117 | | - `-O "\.md$" -O "\.txt$"`. |
| 74 | +Options: |
| 75 | + -P, --Parallel Run analysis in parallel across multiple repositories |

154 | | -psummary -P -O ".*\.lock$" -O "\.md$" -O "/dist/" |
155 | | -``` |
| 114 | + ```sh |
| 115 | + # Skip lock files, docs, and build artifacts |
| 116 | + psummary -P -O ".*\.lock$" -O "\.md$" -O "/dist/" |
| 117 | + ``` |
| 118 | + |
| 119 | +- **`--Pattern <PATTERN>`**: Match different repository markers (e.g., looking |
| 120 | + for `.hg` or custom markers). |
| 121 | + |
| 122 | +- **`-P` vs sequential**: Omit `-P` for deterministic sequential execution |
| 123 | + (useful for debugging or low-memory environments). |
