Micro is a terminal-based text editor that aims to be easy to use and intuitive, while also taking advantage of the full capabilities of modern terminals. It comes as one single, batteries-included, static binary with no dependencies, and you can download and use it right now.

As the name indicates, micro aims to be somewhat of a successor to the nano editor by being easy to install and use in a pinch, but micro also aims to be enjoyable to use full time, whether you work in the terminal because you prefer it (like me), or because you need to (over ssh).

Here is a picture of micro editing its source code.

Features

  • Easy to use and to install

  • Multiple cursors
  • Common keybindings (ctrl-s, ctrl-c, ctrl-v, ctrl-z...)
    • Keybindings can be rebound to your liking
  • Sane defaults
    • You shouldn't have to configure much out of the box (and it is extremely easy to configure)
  • Splits and tabs
  • Nano-like menu to help you remember the keybindings
  • Extremely good mouse support
    • This means mouse dragging to create a selection, double click to select by word, and triple click to select by line

    • Note that while Windows is supported Mingw/Cygwin is not (see below)
  • Plugin system (plugins are written in Lua)
  • Persistent undo
  • Automatic linting and error notifications
  • Syntax highlighting (for over 120 languages!)
  • Colorscheme support

  • Small and simple
  • Easily configurable
  • Macros
  • Common editor things such as undo/redo, line numbers, Unicode support, softwrap...

Installation

To install micro, you can download a prebuilt binary, or you can build it from source.

If you want more information about ways to install micro, see this wiki page.

Prebuilt binaries

All you need to install micro is one file, the binary itself. It's as simple as that!

Download the binary from the releases page.

On that page you'll see the nightly release, which contains binaries for micro which are built every night, and you'll see all the stable releases with the corresponding binaries.

If you'd like to see more information after installing micro, run micro -version.

Installation script

There is a great script which can install micro for you by downloading the latest prebuilt binary. You can find it at https://getmic.ro (the github repo for it is here).

Then you can easily install micro:

$ curl https://getmic.ro | bash

The script will install the micro binary to the current directory.

See the Github page for more information.

Package managers

You can install micro using Homebrew on Mac:

brew install micro

On Debian Linux, you can install micro through snap

snap install micro --classic

Homebrew and snap are the two "officially" maintained package manager distributions of micro.

Micro is also available through other package managers on Linux such as AUR, Nix, and package managers for other operating systems:

  • Windows: Chocolatey and Scoop
    • choco install micro
    • scoop install micro
  • OpenBSD: Available in the ports tree and also available as a binary package
    • pkd_add -v micro

Building from source

If your operating system does not have a binary release, but does run Go, you can build from source.

Make sure that you have Go version 1.11 or greater and Go modules are enabled.

git clone https://github.com/zyedidia/micro
cd micro
make build
sudo mv micro /usr/local/bin # optional

The binary will be placed in the current directory and can be moved to anywhere you like (for example /usr/local/bin).

The command make install will install the binary to $GOPATH/bin or $GOBIN.

You can install directly with go get (go get github.com/zyedidia/micro/cmd/micro) but this isn't recommended because it doesn't build micro with version information, and doesn't disable debug mode.

MacOS terminal

If you are using MacOS, you should consider using iTerm2 instead of the default Mac terminal. The iTerm2 terminal has much better mouse support as well as better handling of key events. For best keybinding behavior, choose xterm defaults under Preferences->Profiles->Keys->Load Preset. The newest versions also support true color.

If you still insist on using the default Mac terminal, be sure to set Use Option key as Meta key under Preferences->Profiles->Keyboard to use option as alt.

Linux clipboard support

On Linux, clipboard support requires the 'xclip' or 'xsel' commands to be installed.

For Ubuntu:

sudo apt-get install xclip

If you don't have xclip or xsel, micro will use an internal clipboard for copy and paste, but it won't work with external applications.

Colors and syntax highlighting

If you open micro and it doesn't seem like syntax highlighting is working, this is probably because you are using a terminal which does not support 256 colors. Try changing the colorscheme to simple by pressing CtrlE in micro and typing set colorscheme simple.

If you are using the default Ubuntu terminal, to enable 256 make sure your TERM variable is set to xterm-256color.

Many of the Windows terminals don't support more than 16 colors, which means that micro's default colorscheme won't look very good. You can either set the colorscheme to simple, or download a better terminal emulator, like mintty.

Plan9, Cygwin, Mingw

These platforms are unfortunately not supported.

Micro uses the amazing tcell library, but this means that micro is restricted to the platforms tcell supports. As a result, micro does not support Plan9, and Cygwin (although this may change in the future). Micro also doesn't support NaCl (but NaCl is deprecated anyways).

Usage

Once you have built the editor, simply start it by running micro path/to/file.txt or simply micro to open an empty buffer.

Micro also supports creating buffers from stdin:

ifconfig | micro

You can move the cursor around with the arrow keys and mouse.

You can also use the mouse to manipulate the text. Simply clicking and dragging will select text. You can also double click to enable word selection, and triple click to enable line selection.

Documentation and Help

Micro has a built-in help system which you can access by pressing Ctrl-E and typing help. Additionally, you can view the help files here:

I also recommend reading the tutorial for a brief introduction to the more powerful configuration features micro offers.

Contributing

If you find any bugs, please report them! I am also happy to accept pull requests from anyone.

You can use the GitHub issue tracker to report bugs, ask questions, or suggest new features.

For a more informal setting to discuss the editor, you can join the Gitter chat.

You can’t perform that action at this time.
