A lightweight terminal IDE that feels like VSCode.
Mouse clicks, git, autocomplete, LSP, themes and an embedded terminal — all inside your terminal.
Written in Rust with ratatui.
Terminal editors usually ask you to learn a new way of working. coder does not.
Click a file, click a tab, drag to select text, press Ctrl+S to save. Everything works how you expect.
It starts instantly and uses very little memory.
- Mouse everywhere — click tabs, files, buttons and checkboxes. Drag to select text, drag borders to resize panels, drag the scrollbar.
- File explorer — lazy tree, create new files and folders inline.
- Syntax highlighting — powered by syntect, works for most languages out of the box.
- LSP support — autocomplete, diagnostics with inline squiggles, and formatting. Just point the config at a language server.
- Git panel — branch, staged/unstaged tree, stage, unstage, revert, commit, fetch, pull, push and commit history.
- Git diff view — open any changed file as a diff tab. Added lines green, removed lines shown inline in red.
- Change gutter — every file shows its git changes next to the line numbers and on the scrollbar.
- Find & replace — in the current file (
Ctrl+F/Ctrl+H) or across the whole project, with regex support. - Embedded terminal — a real shell in a split panel (
Ctrl+J). - Themes — Dracula, Gruvbox, Nord, One Dark, Monokai, Tokyo Night, Catppuccin and more. Switch live, your choice is saved.
- Auto reload — files changed outside the editor reload automatically, unless you have unsaved edits.
Build from source (needs Rust):
git clone https://github.com/eminfedar/coder
cd coder
cargo install --path .Icons use a Nerd Font. If your terminal font has none, run with CODER_ASCII=1.
coder # open the current directory
coder src/ # open a directory
coder main.rs # open a single fileShell completion:
coder completions bash > /etc/bash_completion.d/coder
coder completions zsh >~/.zfunc/_coder
coder completions fish >~/.config/fish/completions/coder.fish| Key | Action |
|---|---|
Ctrl+Q | Quit |
Ctrl+S | Save |
Ctrl+W | Close tab |
Ctrl+B | Toggle sidebar |
Ctrl+J | Toggle terminal |
Ctrl+F / Ctrl+H | Find / Find & replace |
Ctrl+Space | Autocomplete |
Ctrl+Alt+F | Format file |
Editing works the usual way: arrows, Home/End, PageUp/PageDown, Shift to select, Ctrl+←/→ to jump words, Ctrl+C/X/V/Z/Y/A.
Settings live in ~/.config/coder/config.toml. The file is created on first run and you can edit it by hand.
