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.

37 "AltShiftLeft": "SelectWordLeft",
38 "CtrlLeft": "StartOfLine",
39 "CtrlRight": "EndOfLine",
40 "CtrlShiftLeft": "SelectToStartOfLine",
41 "CtrlShiftRight": "SelectToEndOfLine",
42 "CtrlUp": "CursorStart",
43 "CtrlDown": "CursorEnd",

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
146 Micro stores all of the user configuration in its configuration directory.
148 Micro uses the `$XDG_CONFIG_HOME/micro` as the configuration directory. As per
149 the XDG spec, if `$XDG_CONFIG_HOME` is not set, `~/.config/micro` is used as
150 the config directory.
152 Here are the options that you can set:
154 * `colorscheme`: loads the colorscheme stored in
155 $(configDir)/colorschemes/`option`.micro
157 default value: `default`
158 Note that the default colorschemes (default, solarized, and solarized-tc)
159 are not located in configDir, because they are embedded in the micro binary
161 The colorscheme can be selected from all the files in the
162 ~/.config/micro/colorschemes/ directory. Micro comes by default with three
165 * default: this is the default colorscheme.
167 * solarized: this is the solarized colorscheme (used in the screenshot).
168 You should have the solarized color palette in your terminal to use it.
170 * solarized-tc: this is the solarized colorscheme for true color, just
171 make sure your terminal supports true color before using it and that the
172 MICRO_TRUECOLOR environment variable is set to 1 before starting micro.
174 * monokai-tc: this is the monokai colorscheme. It requires true color to
175 look perfect, but the 256 color approximation looks good as well.
177 * atom-dark-tc: this colorscheme is based off of Atom's "dark" colorscheme.
178 It requires true color to look good.
181 * `tabsize`: sets the tab size to `option`
185 * `indentchar`: sets the indentation character
189 * `ignorecase`: perform case-insensitive searches
193 * `syntax`: turns syntax on or off
197 * `tabstospaces`: use spaces instead of tabs
201 * `autoindent`: when creating a new line use the same indentation as the
206 * `cursorline`: highlight the line that the cursor is on in a different color
207 (the color is defined by the colorscheme you are using)
211 * `ruler`: display line numbers
215 * `statusline`: display the status line at the bottom of the screen
219 * `savecursor`: remember where the cursor was last time the file was opened and
220 put it there when you open the file again
224 * `saveundo`: when this option is on, undo is saved even after you close a file
225 so if you close and reopen a file, you can keep undoing
229 * `scrollmargin`: amount of lines you would like to see above and below the cursor
233 * `scrollspeed`: amount of lines to scroll for one scroll event
239 Default plugin options:
241 * `linter`: lint languages on save (supported languages are C, D, Go, Java,
242 Javascript, Lua). Provided by the `linter` plugin.
246 * `autoclose`: Automatically close `{}` `()` `[]` `""` `''`. Provided by the autoclose plugin
250 * `goimports`: Run goimports on save. Provided by the `go` plugin.
254 * `gofmt`: Run gofmt on save. Provided by the `go` plugin.
258 Any option you set in the editor will be saved to the file
259 ~/.config/micro/settings.json so, in effect, your configuration file will be
260 created for you. If you'd like to take your configuration with you to another
261 machine, simply copy the settings.json to the other machine.
