## プロジェクトの歴史と使われ方

F2 is a cross-platform Go CLI for batch-renaming files and directories with a safety-first workflow built around dry runs, conflict detection, undo support, and rich replacement variables.

### プロジェクトの歴史

The GitHub repository was created in 2020, and the changelog lists version 0.1.0 on May 24, 2020 as the initial release. Version 1.0.0 followed on February 22, 2021 with regex filtering, capture groups, dry-run-by-default behavior, conflict detection, recursive renaming, ascending integer replacements, and undo from a map file.

The project evolved from basic batch replacement into a broader renaming toolkit. Later changelog entries added date variables, EXIF and ID3 variables, file hashes, CSV-based renaming, simple mode, find expressions, timezone-aware date handling, and performance improvements.

### 採用の歴史

F2 is packaged for Homebrew, Nix, Scoop, and winget in the input data, matching its cross-platform pitch. Its adoption path is typical for Go CLIs: single executable, prebuilt releases, and enough safety affordances to be trusted for destructive filesystem operations.

### 使われ方

F2 is used for command-line batch renames where shell loops become risky or unreadable: regex replacements, capture-group rewrites, recursive directory changes, media-library organization using EXIF or ID3 metadata, CSV-driven rename maps, conflict resolution, and undoing completed operations.

The official docs emphasize that F2 defaults to a preview workflow. Users review the proposed changes before executing them, which is the main practical distinction between F2 and a quick `rename`, `mv`, or shell one-liner.

### パッケージ好きにとっての重要性

F2 is significant as a polished example of a modern single-purpose Go CLI: prebuilt, cross-platform, heavily documented, and careful around filesystem danger. Package maintainers get one binary with no daemon, service file, or runtime configuration to shepherd.

### タイムライン

- 2020: Repository created and 0.1.0 initial release published.
- 2021: 1.0.0 release adds regex filtering, dry-run-by-default behavior, conflict detection, recursive renaming, and undo.
- 2021: 1.7.0 adds CSV support and platform-aware backup locations.
- 2022: 1.8.0 adds simple mode and opt-in update notification.
- 2025: 2.2.x releases add find expressions, date token conveniences, timezone support, and targeted replacement improvements.

### Related projects

- Traditional Unix tools such as `mv`, shell loops, and `rename` cover smaller renaming jobs but do not provide F2's preview, conflict, metadata-variable, and undo workflow.
- ExifTool is relevant to F2 usage because F2 can use metadata-oriented variables for photo and media renaming workflows.
