## Historique du projet et usages

spaceman-diff is a small shell-oriented image diff helper that plugs into Git diff. It renders changed images as colorful ASCII approximations in the terminal and reports practical metadata such as file-size changes.

### Historique du projet

The official README describes spaceman-diff as a quick drop-in to `git-diff` for image files. It was cobbled together by Zach Holman and depends on jp2a and ImageMagick to convert image content into terminal-friendly output.

The project is intentionally narrow: it handles changed images passed through Git's diff driver mechanism and documents that simple additions or removals are not rendered because Git does not pass those cases to the external diff command in the same way.

### Historique d'adoption

The README documents Homebrew installation, which made the tool easy to try for macOS developers already using Git from the terminal. Its adoption is best understood as a niche Git workflow helper rather than a general-purpose image comparison application.

### Modes d'utilisation

Users install jp2a and ImageMagick, install the `spaceman-diff` script, add image patterns to `~/.config/git/attributes`, and configure a custom Git diff driver in `~/.gitconfig`. After that, ordinary `git diff` invocations can display terminal previews for changed PNG, JPEG, and GIF files.

The README positions the tool as a quick verification aid: it helps a developer confirm that an image change is the intended one and that file size did not change unexpectedly.

### Pourquoi les passionnés de paquets s'y intéressent

spaceman-diff matters to package nerds because it is a classic tiny CLI wrapper around other packaged tools. Its usefulness depends on Git attributes, ImageMagick, jp2a, and the shell all lining up cleanly through a package manager.

It also shows why small formulas exist: a few lines of glue can turn a developer's normal `git diff` habit into a richer terminal workflow without adding a heavyweight GUI dependency.
