The everything menu for your terminal.

One TOML file of commands, profiles, and parameters — served through a searchable, keyboard-driven picker with a live host-info header. Written in Rust; installs as a single binary named exc.

cargo install exc-launcher github

The exc picker: a numbered command grid under a host-info header — the picker — numbered grid, profiles, host header

exc/demodemo.webm

live filter, digit jump, parameter prompt, run — one round trip

exc/picker

$ exc

Type to filter — a live regex with substring fallback — over a column-major numbered grid, laid out like ls. Type a number to jump straight to item N; the prompt glyph flips to # while you do.

Enter run · Esc quit
Tab / Shift-Tab switch profile
Ctrl-H Ctrl-J Ctrl-K Ctrl-L move — vim chords; bare letters stay filter input, the same trade-off fzf makes

The picker narrowing the grid with a live regex filter — regex filter, substring fallback

exc/config

$ exc init

Everything lives in ~/.config/exc/config.toml: profiles group commands, and {{param}} placeholders prompt at run time — with defaults, and secret = true for masked input. Commands run through sh -c with inherited stdio, so ssh, fzf, and sudo behave; project-local configs load with --config.

[[profiles]]
name = "network"
label = "Network"

  [[profiles.commands]]
  name = "cert-check"
  description = "Check the TLS certificate for a domain"
  command = "openssl s_client -connect {{domain}}:443"

    [[profiles.commands.params]]
    name = "domain"
    prompt = "Domain to check"
    secret = false

A parameter prompt with masked secret input — prompted params — secret = true masks input

exc/sysinfo

$ exc sysinfo

A host panel in three cost tiers: what is cheap reads synchronously at startup — OS, kernel, uptime, memory, disk, CPU, load, local IP, battery, top processes, GPU. What is slow — public IP, package updates, net throughput — refreshes in the background and patches in without blocking. Underneath, per-platform native APIs: sysctl and IOKit on macOS, /proc and /sys on Linux, kernel32 and PowerShell CIM on Windows.

The sysinfo panel: host, memory, disk, CPU, network — three tiers — sync, background, native

exc/src

$ grep -rl unsafe src/

src/hostinfo/platform/macos.rs
src/hostinfo/platform/linux.rs
src/hostinfo/platform/windows.rs
src/hostinfo/platform/macos/iokit_ffi.rs

That is the whole list. The picker, executor, config, and theme layers are safe Rust: ownership and borrowing rule out use-after-free, double-free, and data races at compile time, with no garbage collector at run time. unsafe exists — confined to the OS FFI in the hostinfo platform layer, where the kernel's API leaves no choice. A panic hook leaves the alternate screen and re-enables the terminal, so even a crash cannot wedge your session; errors are typed with thiserror.

exc/themes

$ theme nord

Built-in default, dark, and mono themes, an inline [theme] table or a theme_file, and ten bundled palettes. Six fields — accent, border, text, muted, selected background and foreground — and NO_COLOR is respected.

exc/cli

$ exc man

Bare exc opens the picker; exc <name> runs the first substring match. Subcommands cover the rest — and exc man renders roff from the same clap definitions as --help, so the man page cannot drift from the binary.

$ cargo install exc-launcher

Rust 1.95 or newer, edition 2024, MIT licensed. No Rust toolchain on the box? launcher.sh in the repo is a dependency-free bash fallback. The EXAMPLES.md cookbook covers profiles, parameters, and themes.
