A terminal-based Markdown and code editor with WYSIWYG rendering and LSP support.

mq-edit is a Rust-based TUI (Text User Interface) editor that provides:

• Markdown WYSIWYG: The line under the cursor displays source, other lines show rich formatted text
• LSP Integration: Full Language Server Protocol support for code intelligence
• Multi-language support: Rust, Python, MQ (Markdown Query Language), and more

Built on top of the mq-markdown parser with full LSP capabilities.

mq-edit supports pipe mode, allowing you to read from stdin and write to stdout. This is useful for combining with mq and other command-line tools. In pipe mode, pressing Esc exits immediately without a save confirmation dialog — the edited content is written to stdout on exit.

# Edit mq output interactively, then pass the result to the next command
cat README.md | mq '.h' | mq-edit | mq 'downcase()'

# Extract links, edit them, and save to a file
cat README.md | mq '.link' | mq-edit > links.md

# Transform markdown with mq, review and edit interactively, then write back
mq '.[] | select(.h.depth > 1)' README.md | mq-edit > headings.md

# Edit text from clipboard (macOS)
pbpaste | mq-edit | pbcopy

mq-edit uses a TOML configuration file for customizing keybindings and LSP servers.

• Linux: ~/.config/mq/edit/config.toml
• macOS: ~/Library/Application Support/mq/edit/config.toml
• Windows: %APPDATA%\mq/edit\config.toml

Run mq-edit --init-config to create a default configuration file with all available keybindings.

Configure language servers for different file types:

# Rust Language Server
[lsp.servers.rust]
command = "rust-analyzer"
args = []
enable_completion = true
enable_diagnostics = true
enable_goto_definition = true

# MQ Language Server (for .mq files)
[lsp.servers.mq]
command = "mq-lsp"
args = []
enable_completion = true
enable_diagnostics = true
enable_goto_definition = true

# Python Language Server
[lsp.servers.python]
command = "pyright-langserver"
args = ["--stdio"]
enable_completion = true
enable_diagnostics = true
enable_goto_definition = true

Edit the config file to change keybindings. Example:

[keybindings.quit]
code = "q"
modifiers = ["ctrl"]  # Ctrl+Q to quit

[keybindings.quit_alt]
code = "esc"
modifiers = []  # Esc to quit (alternative)

[keybindings.save]
code = "s"
modifiers = ["ctrl"]  # Ctrl+S to save

Choose from built-in syntax highlighting themes:

[editor]
# Syntax highlighting theme
theme = "base16-ocean.dark"  # Default dark theme

# Other available themes:
# theme = "base16-ocean.light"     # Light ocean theme
# theme = "base16-mocha.dark"      # Mocha dark theme
# theme = "base16-eighties.dark"   # Eighties dark theme
# theme = "InspiredGitHub"         # GitHub-inspired light theme
# theme = "Solarized (dark)"       # Solarized dark
# theme = "Solarized (light)"      # Solarized light

All themes are provided by the syntect library.

Note: Default keybindings have been changed to avoid conflicts with VSCode, Zellij, and other editors. All keybindings are customizable via the config file.

• Home - Start of line
• End - End of line
• Page Up/Down - Scroll page

• Backspace - Delete character
• Tab - Insert tab

• Ctrl+S - Save file (opens save-as dialog for new files)
• Ctrl+Q or Esc - Quit application
• Alt+B - Toggle file browser (changed from Ctrl+B to avoid VSCode conflict)

mq-edit has built-in support for mq (Markdown Query Language). Press Ctrl+E to open the query dialog and run mq queries against the current document.

• Esc - Close dialog

The query result is inserted at the current cursor position, and the cursor remains at the insertion start so you can review the output.

• Ctrl+G - Go to line (opens line number dialog)

• Up/Down - Navigate files and directories
• Right - Expand directory
