jterm4

A simple GTK4 + VTE terminal with tab support.

Tabs

When creating a new tab, jterm4 attempts to inherit the current tab's working directory (via VTE's current directory URI). If unavailable, it falls back to $HOME.

Each tab also includes a close button in the tab header.

On exit, jterm4 saves the current tab list (and active tab) and restores them on next start. The state is stored under your XDG config directory (typically ~/.config/jterm4/tabs.state).

Configuration (environment variables)

• JTERM4_LOG: log level (off|error|warn|info|debug|trace). Falls back to RUST_LOG. Default: warn.
• JTERM4_FONT: Pango font description string. Default: SauceCodePro Nerd Font Regular 12.
• JTERM4_FONT_SCALE: default font scale (0.1-10.0). Default: 1.0.
• JTERM4_SCROLLBACK: scrollback line count (>=0). Default: 5000.
• JTERM4_OPACITY: initial window opacity (0.01-1.0). Default: 0.95.
• JTERM4_FG, JTERM4_BG, JTERM4_CURSOR, JTERM4_CURSOR_FG: colors accepted by GTK (#RRGGBB etc).

Shell selection

On startup, each terminal chooses a shell like this:

• Prefer fish when available.
• If fish has a working bass, run bass "source ~/.bashrc" once before showing the prompt (so bash-style environment changes from .bashrc are applied).
• If fish is not available, fall back to bash -l.

Notes:

• This project does not need to edit ~/.config/fish/config.fish.
• bass is expected to import environment variables; importing bash aliases into fish is intentionally avoided because many bash aliases contain bash-only syntax.

Installing bass (fish)

If you want .bashrc environment imported into fish, install bass:

• With fisher: fisher install edc/bass

(Any other method that provides a bass function in fish also works.)
