**micro** is a terminal-based text editor that aims to be easy to use and intuitive, while also taking advantage of the capabilities
|
|
of modern terminals. It comes as a single, batteries-included, static binary with no dependencies; you can download and use it right now!
|
|
|
|
As its name indicates, micro aims to be somewhat of a successor to the nano editor by being easy to install and use.
|
|
It strives to be enjoyable as a full-time editor for people who prefer to work in a terminal, or those who regularly edit files over SSH.
|
|
|
|
Here is a picture of micro editing its source code.

## Installation
|
|
|
|
To install micro, you can download a [prebuilt binary](https://github.com/zyedidia/micro/releases), or you can build it from source.
|
|
|
|
If you want more information about ways to install micro, see this [wiki page](https://github.com/zyedidia/micro/wiki/Installing-Micro).
|
|
|
|
Use `micro -version` to get the version information after installing. It is only guaranteed that you are installing the most recent
|
|
stable version if you install from the prebuilt binaries, Homebrew, or Snap.
|
|
|
|
A desktop entry file and man page can be found in the [assets/packaging](https://github.com/zyedidia/micro/tree/master/assets/packaging) directory.
|
|
|
|
### 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](https://github.com/zyedidia/micro/releases) page.
|
|
|
|
### Installation script
|
|
|
|
There is a script which can install micro for you by downloading the latest prebuilt binary. You can find it at <https://getmic.ro>.
|
|
|
|
You can easily install micro by running
|
|
|
|
```bash
|
|
curl https://getmic.ro | bash
|
|
```
|
|
|
|
The script will place the micro binary in the current directory. From there, you can move it to a directory on your path of your choosing (e.g. `sudo mv micro /usr/bin`). See its [GitHub repository](https://github.com/benweissmann/getmic.ro) for more information.
|
|
|
|
To uninstall micro, simply remove the binary, and the configuration directory at `~/.config/micro`.
|
|
|
|
### Package managers
|
|
|
|
You can install micro using Homebrew on Mac:
|
|
|
|
```
|
|
brew install micro
|
|
```
|
|
|
|
**Note for Mac:** All micro keybindings use the control or alt (option) key, not the command
|
|
key. By default, macOS terminals do not forward alt key events. To fix this, please see
|
|
the section on [macOS terminals](https://github.com/zyedidia/micro#macos-terminal) further below.
|
|
|
|
On Linux, you can install micro through [snap](https://snapcraft.io/docs/core/install)
|
|
|
|
```
|
|
snap install micro --classic
|
|
```
|
|
|
|
**Note for Linux:** for interfacing with the local system clipboard, `xclip` or `xsel`
|
|
must be installed. Please see the section on [Linux clipboard support](https://github.com/zyedidia/micro#linux-clipboard-support)
|
|
further below.
|
|
|
|
Micro is also available through other package managers on Linux such as apt, dnf, AUR, Nix, and package managers
|
|
for other operating systems. These packages are not guaranteed to be up-to-date.
|
|
|
|
* Linux: Available in distro-specific package managers.
|
|
* `apt install micro` (Ubuntu 20.04 `focal`, and Debian `unstable | testing | buster-backports`). At the moment, this package (2.0.1-1) is outdated and has a known bug where debug mode is enabled.
|
|
* `dnf install micro` (Fedora).
|
|
* `yay -S micro` (Arch Linux).
|
|
* See [wiki](https://github.com/zyedidia/micro/wiki/Installing-Micro) for details about CRUX, Termux.
|
|
* Windows: [Chocolatey](https://chocolatey.org) and [Scoop](https://github.com/lukesampson/scoop).
|
|
* `choco install micro`.
|
|
* `scoop install micro`.
|
|
* OpenBSD: Available in the ports tree and also available as a binary package.
|
|
* `pkd_add -v micro`.
|
|
* NetBSD, macOS, Linux, Illumos, etc. with [pkgsrc](http://www.pkgsrc.org/)-current:
|
|
* `pkg_add 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 (necessary for the plugin manager),
|
|
and doesn't disable debug mode.
|
|
|
|
### Fully static binary
|
|
|
|
By default, the micro binary will dynamically link with core system libraries (this is generally
|
|
recommended for security and portability). However, there is a fully static prebuilt binary that
|
|
is provided for amd64 as `linux-static.tar.gz`, and to build a fully static binary from source, run
|
|
|
|
```
|
|
CGO_ENABLED=0 make build
|
|
```
|
|
|
|
### macOS terminal
|
|
|
|
If you are using macOS, you should consider using [iTerm2](http://iterm2.com/) instead of the default terminal (Terminal.app). 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->Presets...`, and select `Esc+` for `Left Option Key` in the same menu. 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 <kbd>option</kbd> as <kbd>alt</kbd>.
|
|
|
|
### Linux clipboard support
|
|
|
|
On Linux, clipboard support requires:
|
|
|
|
- On X11, the `xclip` or `xsel` commands (for Ubuntu: `sudo apt install xclip`)
|
|
- On Wayland, the `wl-clipboard` command
|
|
|
|
If you don't have these commands, 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 color mode. Try changing the color scheme to `simple`
|
|
by pressing <kbd>Ctrl-e</kbd> 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 color scheme won't look very good. You can either set
|
|
the color scheme to `simple`, or download and configure a better terminal emulator
|
|
than the Windows default.
|
|
|
|
### Cygwin, Mingw, Plan9
|
|
|
|
Cygwin, Mingw, and Plan9 are unfortunately not officially supported. In Cygwin and Mingw, micro will often work when run using
|
|
the `winpty` utility:
|
|
|
|
```
|
|
winpty micro.exe ...
|
|
```
|
|
|
|
Micro uses the amazing [tcell library](https://github.com/gdamore/tcell), 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 (which is deprecated anyway).
|
|
|
|
## Usage
|
|
|
|
Once you have built the editor, start it by running `micro path/to/file.txt` or `micro` to open an empty buffer.
|
|
|
|
micro also supports creating buffers from `stdin`:
|
|
|
|
```sh
|
|
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
