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.

# 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).
|
|
|
|
### 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.
|
|
|
|
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](https://github.com/benweissmann/getmic.ro)).
|
|
|
|
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](https://github.com/benweissmann/getmic.ro) for more information.
|
|
|
|
### Package managers
|
|
|
|
You can install micro using Homebrew on Mac:
|
|
|
|
```
|
|
brew install micro
|
|
```
|
|
|
|
On Windows, you can install micro through [Chocolatey](https://chocolatey.org/) or [Scoop](https://github.com/lukesampson/scoop):
|
|
|
|
```
|
|
choco install micro
|
|
```
|
|
|
|
or
|
|
|
|
```
|
|
scoop install micro
|
|
```
|
|
|
|
On Linux, you can install micro through [snap](https://snapcraft.io/docs/core/install)
|
|
|
|
```
|
|
snap install micro --classic
|
|
```
|
|
|
|
On OpenBSD, micro is available in the ports tree. It is also available as a binary package.
|
|
|
|
```
|
|
pkg_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 1.5 or greater (Go 1.4 will work if your version supports CGO) and that your `GOPATH` env variable is set (I recommend setting it to `~/go` if you don't have one).
|
|
|
|
```
|
|
go get -d github.com/zyedidia/micro/cmd/micro
|
|
cd $GOPATH/src/github.com/zyedidia/micro
|
|
make install
|
|
```
|
|
|
|
The binary will then be installed to `$GOPATH/bin` (or your `$GOBIN`).
|
|
|
|
Please make sure that when you are working with micro's code, you are working on your `GOPATH`.
|
|
|
|
You can install directly with `go get` (`go get -u github.com/zyedidia/micro/cmd/micro`) but this isn't recommended because it doesn't build micro with version information which is useful for the plugin manager.
|
|
|
|
### MacOS terminal
|
|
|
|
If you are using MacOS, you should consider using [iTerm2](http://iterm2.com/) 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.
|
|
|
|
### Linux clipboard support
|
|
|
|
On Linux, clipboard support requires the 'xclip' or 'xsel' commands to be installed.
|
|
|
|
For Ubuntu:
|
|
|
|
```sh
|
|
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 color. 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
|
|
|
|
Please note that 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 (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`:
|
|
|
|
```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

|
|

|
|
a brief introduction to the more powerful configuration features micro offers.
