3 Micro is a terminal-based text editor that aims to be easy to use and intuitive,
4 while also taking advantage of the full capabilities of modern terminals.
8 Once you have built the editor, simply start it by running
9 `micro path/to/file.txt` or simply `micro` to open an empty buffer.
11 Micro also supports creating buffers from stdin:
17 You can move the cursor around with the arrow keys and mouse.
21 Here are the default keybindings in json form which is also how
22 you can rebind them to your liking.

74 "CtrlR": "ToggleRuler",
80 "CtrlE": "CommandMode",
83 // Emacs-style keybindings
86 "Alt-a": "StartOfLine",
93 You can use the alt keys + arrows to move word by word.
94 Ctrl left and right move the cursor to the start and end of the line, and
95 ctrl up and down move the cursor the start and end of the buffer.
97 You can hold shift with all of these movement actions to select while moving.
99 The bindings may be rebound using the `~/.config/micro/bindings.json`
100 file. Each key is bound to an action.
102 For example, to bind `Ctrl-y` to undo and `Ctrl-z` to redo, you could put the
103 following in the `bindings.json` file.
112 ### Possible commands
114 You can execute an editor command by pressing `Ctrl-e` followed by the command.
115 Here are the possible commands that you can use.
117 * `quit`: Quits micro.
119 * `save`: Saves the current buffer.
121 * `replace "search" "value" flags`: This will replace `search` with `value`.
122 The `flags` are optional.
123 At this point, there is only one flag: `c`, which enables `check` mode
124 which asks if you'd like to perform the replacement each time
126 Note that `search` must be a valid regex. If one of the arguments
127 does not have any spaces in it, you may omit the quotes.
129 * `set option value`: sets the option to value. Please see the next section for
130 a list of options you can set.
132 * `run sh-command`: runs the given shell command in the background. The
133 command's output will be displayed in one line when it finishes running.
135 * `bind key action`: creates a keybinding from key to action. See the sections on
136 keybindings above for more info about what keys and actions are available.
138 * `vsplit filename`: opens a vertical split with `filename`. If no filename is
139 provided, a vertical split is opened with an empty buffer
141 * `hsplit filename`: same as `vsplit` but opens a horizontal split instead of
144 * `tab filename`: opens the given file in a new tab.
148 Micro stores all of the user configuration in its configuration directory.
150 Micro uses the `$XDG_CONFIG_HOME/micro` as the configuration directory. As per
151 the XDG spec, if `$XDG_CONFIG_HOME` is not set, `~/.config/micro` is used as
152 the config directory.
154 Here are the options that you can set:
156 * `colorscheme`: loads the colorscheme stored in
157 $(configDir)/colorschemes/`option`.micro
159 default value: `default`
160 Note that the default colorschemes (default, solarized, and solarized-tc)
161 are not located in configDir, because they are embedded in the micro binary
163 The colorscheme can be selected from all the files in the
164 ~/.config/micro/colorschemes/ directory. Micro comes by default with three
167 * default: this is the default colorscheme.
169 * solarized: this is the solarized colorscheme (used in the screenshot).
170 You should have the solarized color palette in your terminal to use it.
172 * solarized-tc: this is the solarized colorscheme for true color, just
173 make sure your terminal supports true color before using it and that the
174 MICRO_TRUECOLOR environment variable is set to 1 before starting micro.
176 * monokai-tc: this is the monokai colorscheme. It requires true color to
177 look perfect, but the 256 color approximation looks good as well.
179 * atom-dark-tc: this colorscheme is based off of Atom's "dark" colorscheme.
180 It requires true color to look good.
183 * `tabsize`: sets the tab size to `option`
187 * `indentchar`: sets the indentation character
191 * `ignorecase`: perform case-insensitive searches
195 * `syntax`: turns syntax on or off
199 * `tabstospaces`: use spaces instead of tabs
203 * `autoindent`: when creating a new line use the same indentation as the
208 * `cursorline`: highlight the line that the cursor is on in a different color
209 (the color is defined by the colorscheme you are using)
213 * `ruler`: display line numbers
217 * `statusline`: display the status line at the bottom of the screen
221 * `savecursor`: remember where the cursor was last time the file was opened and
222 put it there when you open the file again
226 * `saveundo`: when this option is on, undo is saved even after you close a file
227 so if you close and reopen a file, you can keep undoing
231 * `scrollmargin`: amount of lines you would like to see above and below the cursor
235 * `scrollspeed`: amount of lines to scroll for one scroll event
241 Default plugin options:
243 * `linter`: lint languages on save (supported languages are C, D, Go, Java,
244 Javascript, Lua). Provided by the `linter` plugin.
248 * `autoclose`: Automatically close `{}` `()` `[]` `""` `''`. Provided by the autoclose plugin
252 * `goimports`: Run goimports on save. Provided by the `go` plugin.
256 * `gofmt`: Run gofmt on save. Provided by the `go` plugin.
260 Any option you set in the editor will be saved to the file
261 ~/.config/micro/settings.json so, in effect, your configuration file will be
262 created for you. If you'd like to take your configuration with you to another
263 machine, simply copy the settings.json to the other machine.
