macro

A fast terminal text editor written in Rust. Designed as a replacement for micro with better performance, a built-in file tree, and LSP autocomplete.

Features

• Integrated file tree — full screen when no file is open, split view when a file is open
• Syntax highlighting for all major languages (via syntect, pure Rust)
• LSP autocomplete — triggers automatically while typing, uses system language servers
• Tabs — open up to 8 files simultaneously, switch by clicking
• Mouse support — click to position cursor, scroll wheel, click to navigate tree
• Line numbers
• Config file at ~/.config/macro/config.toml

Usage

macro [PATH]

• macro — open current directory as file tree
• macro /path/to/file — open file in editor
• macro /path/to/dir — open directory as file tree root
• macro src/new/file.rs — create missing directories and file, then open it
• macro --help — show help
• macro --version — print version

LSP Autocomplete

Completions appear automatically while typing. The editor uses system-installed language servers — install what you need:

Language	Server	Install
Rust	rust-analyzer	dnf install rust-analyzer
Python	pylsp	pip install python-lsp-server
C / C++	clangd	dnf install clang-tools-extra
Go	gopls	go install golang.org/x/tools/gopls@latest
JS / TS	typescript-language-server	npm i -g typescript-language-server typescript

If a language server is not installed, the editor works normally without completions.
