File listings in Codec now look like a modern Linux terminal's: ls colors files by type in the theme's palette, and, with eza, shows a Nerd Font icon by each name, in any font.

Colors

ls colors folders, links and executables, and every other file in the color its icon has in the file tree (Swift red, Markdown blue, lockfiles gray). Panes get CLICOLOR, LSCOLORS (macOS's ls) and LS_COLORS (eza, GNU ls, zsh's completion menu), each only if it isn't already set, and the user's .zshrc still wins. The colors are named as terminal colors, so a listing follows the theme; only the accent is 24-bit. FileType.color moved into CodecCore, so the file tree and FileListingColors share one table. On by default: Settings › Shell › Color files by type.

eza, with icons

Settings › Shell › Use eza for ls (off by default) makes ls an alias for eza --icons=auto --group-directories-first, set by the zsh integration at the first prompt. An ls alias or function of the user's own is kept, unless all it does is turn on color (ls -G).

When eza isn't installed, the same section shows Install with Homebrew, which runs brew install eza in a new tab (where it can be watched and answered) and turns the setting on. Without Homebrew, it links to eza's install instructions.

Icons in any font

Codec now bundles Nerd Fonts' symbols (Resources/Fonts, MIT, 2.4 MB; build-app.sh copies it into the app). SwiftTerm takes one fallback font, so Codec's glyph font gets a CoreText cascade list that reaches the symbols. Codec claims only the private-use characters and power symbols that font has: they're placed as icons, and Powerline's separators stretch to fill their cell. Ordinary symbols (♥ ⚡ ❯) stay with the system, and a patched Nerd Font keeps its own. Starship, lsd and Neovim file trees benefit too.

Screenshots

All of docs/images was retaken with make screenshots. The tour has a new listing shot (above), used in the command line docs. It now clears NO_COLOR, which swift test sets and eza honors. Plain ls in the theme grid now shows folders in color:

Testing

• swift build -j 2 --build-tests, swift test -j 2 --skip-build: all 518 pass. New tests cover the LS_COLORS table, the eza alias in a real zsh (installed, replacing a color-only alias, keeping a user's own, no eza, setting off), the icon fallback down to the run's font, the pane's environment, finding eza and Homebrew, and running a command in a new tab.
• ARCHS="arm64 x86_64" scripts/build-app.sh release: builds, with the font in Contents/Resources/Fonts.
• Tried locally with eza 0.23.5 from Homebrew. The Install with Homebrew row wasn't checked on screen, since eza is installed on this Mac.
• Icons fit in one cell, so they're a little smaller than in terminals that let them overflow.
