Platform Notes

CLI Options

Testing

# Unit tests
cargo test

# ISO-functional test against Perl ExifTool's 194 test files
# No Perl required — reference files included in tests/expected/
./scripts/test_iso.sh

# 194/194 files (100%) produce identical tag names — 11625 tags verified

Building

git clone https://github.com/Le-Syl21/exiftool-rs
cd exiftool-rs

# CLI only
cargo build --release

# CLI + GUI
cargo build --release --features gui

The gui feature is optional and not included by default. Without it, the GUI dependencies (egui, eframe, image, rfd, noto-fonts-dl) are not downloaded or compiled.
