`ls-f` is a friendly drop-in wrapper around GNU `ls` that adds Nerd Font icons, color hints, and a few quality-of-life improvements while still letting your familiar flags pass straight through. Use it as a standalone command or alias it to `ls` for a richer directory view.

Reload your shell configuration afterwards (e.g. `source ~/.zshrc`).

+## Testing
50
+
51
+ls-f includes automated tests for core functionality:
52
+
53
+```bash
54
+# Run the test suite
55
+python3 test_lsf.py
56
+
57
+# Run with coverage
58
+pip install coverage
59
+coverage run test_lsf.py
60
+coverage report
61
+```
62
+
63
+Tests cover:
64
+- Column formatter (column.py) with different layouts and inputs
65
+- Basic lsf functionality (--version, --help, --no-icons)
66
+- Flag parsing and error handling
67
+- Unicode icon handling
68
+
69
+Continuous integration runs tests across multiple Python (3.7-3.11) and Bash versions.
70
+

## Feature Highlights
46
72
- Icons & colors that automatically match hundreds of common file types
47
73
- Works out-of-the-box with long listings (`-l`), recursion (`-R`), and hidden files (`-A`, `-a`)
