Building rfig: a Rust terminal autocomplete and open-source Fig alternative

Description and use

rfig is an open‑source Rust terminal autocomplete that provides IDE‑style command completion without replacing the shell. It supports zsh, Bash 4.4+, and Fish 3.6+ on macOS and Linux, offering a completion menu with nested subcommands, dynamic arguments, and history‑based autosuggestions.

Problem

Need IDE‑style command completion in the terminal without replacing the shell that runs commands.

Outcome

rfig delivers IDE‑style completion in the terminal, offering nested subcommands, dynamic arguments, and history‑based autosuggestions without replacing the underlying shell.

Workflow

• Install rfig via Homebrew: brew install tamia6/tap/rfig rfig setup
• Open a new shell
• Start typing to see completion menu and autosuggestions

Evidence

I built rfig because I wanted IDE‑style completion in the terminal without replacing the shell that actually runs my commands.

Source

rfig is an independent, open‑source terminal autocomplete project inspired by Fig.
