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 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.
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
# Features
- Easy to use and install.
- No dependencies or external files are needed just the binary you can download further down the page.
- Multiple cursors.
- Common keybindings (<kbd>Ctrl-s</kbd>, <kbd>Ctrl-c</kbd>, <kbd>Ctrl-v</kbd>, <kbd>Ctrl-z</kbd>, …).
- 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.
- Cross-platform (it should work on all the platforms Go runs on).
- Note that while Windows is supported Mingw/Cygwin is not (see below).
- Plugin system (plugins are written in Lua).
- micro has a built-in plugin manager to automatically install, remove, and update plugins.
- Built-in diff gutter.
- Simple autocompletion.
- Persistent undo.
- Automatic linting and error notifications.
- Syntax highlighting for over [130 languages](runtime/syntax).
- Color scheme support.
- By default, micro comes with 16, 256, and true color themes.
- True color support (set the `MICRO_TRUECOLOR` environment variable to 1 to enable it).
- Copy and paste with the system clipboard.
- Small and simple.
- Easily configurable.
- Macros.
- Common editor features such as undo/redo, line numbers, Unicode support, soft wrapping, …

## Installation
Although not yet implemented, I hope to add more features such as autocompletion ([#174](https://github.com/zyedidia/micro/issues/174)) or a tree view ([#249](https://github.com/zyedidia/micro/issues/249)) in the future.
# 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.
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 script which can install micro for you by downloading the latest prebuilt binary. You can find it at <https://getmic.ro>.
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)).
You can easily install micro by running
Then you can easily install micro:
```bash
curl https://getmic.ro | 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.
The script will install the micro binary to the current directory.
To uninstall micro, simply remove the binary, and the configuration directory at `~/.config/micro`.
See the [Github page](https://github.com/benweissmann/getmic.ro) for more information.
### Package managers
@@ -109,9 +106,17 @@ 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 Windows, you can install micro through [Chocolatey](https://chocolatey.org/) or [Scoop](https://github.com/lukesampson/scoop):
```
choco install micro
```
or
```
scoop install micro

**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.
On OpenBSD, micro is available in the ports tree. It is also available as a binary package.
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).
* `pacman -S micro` (Arch Linux).
* `eopkg install micro` (Solus).
* 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`
```
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 1.11 or greater and Go modules are enabled.
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).
```
git clone https://github.com/zyedidia/micro
cd micro
make build
sudo mv micro /usr/local/bin # optional
go get -d github.com/zyedidia/micro/cmd/micro
cd $GOPATH/src/github.com/zyedidia/micro
make install
```
The binary will be placed in the current directory and can be moved to
anywhere you like (for example `/usr/local/bin`).
The binary will then be installed to `$GOPATH/bin` (or your `$GOBIN`).
The command `make install` will install the binary to `$GOPATH/bin` or `$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 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.
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.
### Fully static binary
### MacOS terminal
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>.

The newest versions also support true color.
### Linux clipboard support
On Linux, clipboard support requires:
On Linux, clipboard support requires the 'xclip' or 'xsel' commands to be installed.
- On X11, the `xclip` or `xsel` commands (for Ubuntu: `sudo apt install xclip`)
- On Wayland, the `wl-clipboard` command
For Ubuntu:
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.
```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 mode. Try changing the color scheme to `simple`
by pressing <kbd>Ctrl-e</kbd> in micro and typing `set colorscheme simple`.
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 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
### Plan9, Cygwin
Cygwin, Mingw, and Plan9 are unfortunately not officially supported. In Cygwin and Mingw, micro will often work when run using
the `winpty` utility:

.SH NAME
micro \- A modern and intuitive terminal-based text editor
.SH SYNOPSIS
@@ -14,99 +21,40 @@ of modern terminals. It comes as one single, batteries-included, static binary w
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).
Use Ctrl-q to quit, Ctrl-s to save, and Ctrl-g to open the in-editor help menu.

.RE
.SH CONFIGURATION
Micro uses $MICRO_CONFIG_HOME as the configuration directory.
If this environment variable is not set, it uses $XDG_CONFIG_HOME/micro instead.
If that environment variable is not set, it uses ~/.config/micro as the configuration directory.
In the documentation, we use ~/.config/micro to refer to the configuration directory
(even if it may in fact be somewhere else if you have set either of the above environment variables).
Micro uses
\fI$XDG_CONFIG_HOME/micro\fR
for configuration by default. If it is not set, micro uses ~/.config/micro.
Two main configuration files are settings.json, containing the user's
settings, and bindings.json, containing the user's custom keybindings.
.SH ENVIRONMENT
Micro's behaviour can be changed by setting environment variables, of which there is currently only one:
\fIMICRO_TRUECOLOR\fR.
When MICRO_TRUECOLOR is set to 1, micro will attempt to treat your terminal as a true-color terminal and will be able to make full use of the true-color colorschemes that are included with micro. If MICRO_TRUECOLOR is not set or is set to 0, then micro will only make use of 256 color features and will internally map true-color colorschemes to the nearest colors available. For more information see micro's documentation.

This is a modified version of `go-shellwords` for the micro editor.
# go-shellwords
[![Coverage Status](https://coveralls.io/repos/mattn/go-shellwords/badge.png?branch=master)](https://coveralls.io/r/mattn/go-shellwords?branch=master)
[![Build Status](https://travis-ci.org/mattn/go-shellwords.svg?branch=master)](https://travis-ci.org/mattn/go-shellwords)
Parse line as shell words.
## Usage
```go
args, err := shellwords.Parse("./foo --bar=baz")
// args should be ["./foo", "--bar=baz"]
```
```go
os.Setenv("FOO", "bar")
p := shellwords.NewParser()
p.ParseEnv = true
args, err := p.Parse("./foo $FOO")
// args should be ["./foo", "bar"]
```
```go
p := shellwords.NewParser()
p.ParseBacktick = true
args, err := p.Parse("./foo `echo $SHELL`")
// args should be ["./foo", "/bin/bash"]
```
```go
shellwords.ParseBacktick = true
p := shellwords.NewParser()
args, err := p.Parse("./foo `echo $SHELL`")
// args should be ["./foo", "/bin/bash"]

# Terminfo parser
This terminfo parser was written by the authors of [tcell](https://github.com/gdamore/tcell). We are using it here
to compile the terminal database if the terminal entry is not found in set of precompiled terminals.
The source for `mkinfo.go` is adapted from tcell's `mkinfo` tool to be more of a library.
