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",

72 "PageDown": "CursorPageDown",
73 "CtrlG": "ToggleHelp",
74 "CtrlR": "ToggleRuler",

82 // Emacs-style keybindings
85 "Alt-a": "StartOfLine",
92 You can use the alt keys + arrows to move word by word.
93 Ctrl left and right move the cursor to the start and end of the line, and
94 ctrl up and down move the cursor the start and end of the buffer.
96 You can hold shift with all of these movement actions to select while moving.
98 The bindings may be rebound using the `~/.config/micro/bindings.json`
99 file. Each key is bound to an action.
101 For example, to bind `Ctrl-y` to undo and `Ctrl-z` to redo, you could put the
102 following in the `bindings.json` file.
111 ### Possible commands
113 You can execute an editor command by pressing `Ctrl-e` followed by the command.
114 Here are the possible commands that you can use.
116 * `quit`: Quits micro.
117 * `save`: Saves the current buffer.
119 * `replace "search" "value" flags`: This will replace `search` with `value`.
120 The `flags` are optional.
121 At this point, there is only one flag: `c`, which enables `check` mode
122 which asks if you'd like to perform the replacement each time
124 Note that `search` must be a valid regex. If one of the arguments
125 does not have any spaces in it, you may omit the quotes.
127 * `set option value`: sets the option to value. Please see the next section for
128 a list of options you can set.
130 * `run sh-command`: runs the given shell command in the background. The
131 command's output will be displayed in one line when it finishes running.
133 * `bind key action`: creates a keybinding from key to action. See the sections on
134 keybindings above for more info about what keys and actions are available.
138 Micro stores all of the user configuration in its configuration directory.
140 Micro uses the `$XDG_CONFIG_HOME/micro` as the configuration directory. As per
141 the XDG spec, if `$XDG_CONFIG_HOME` is not set, `~/.config/micro` is used as
142 the config directory.
144 Here are the options that you can set:
146 * `colorscheme`: loads the colorscheme stored in
147 $(configDir)/colorschemes/`option`.micro
149 default value: `default`
150 Note that the default colorschemes (default, solarized, and solarized-tc)
151 are not located in configDir, because they are embedded in the micro binary
153 The colorscheme can be selected from all the files in the
154 ~/.config/micro/colorschemes/ directory. Micro comes by default with three
157 * default: this is the default colorscheme.
158 * solarized: this is the solarized colorscheme (used in the screenshot).
159 You should have the solarized color palette in your terminal to use it.
160 * solarized-tc: this is the solarized colorscheme for true color, just
161 make sure your terminal supports true color before using it and that the
162 MICRO_TRUECOLOR environment variable is set to 1 before starting micro.
165 * `tabsize`: sets the tab size to `option`
169 * `indentchar`: sets the indentation character
173 * `ignorecase`: perform case-insensitive searches
177 * `syntax`: turns syntax on or off
181 * `tabstospaces`: use spaces instead of tabs
185 * `autoindent`: when creating a new line use the same indentation as the
190 * `cursorline`: highlight the line that the cursor is on in a different color
191 (the color is defined by the colorscheme you are using)
195 * `ruler`: display line numbers
199 * `statusline`: display the status line at the bottom of the screen
203 * `savecursor`: remember where the cursor was last time the file was opened and
204 put it there when you open the file again
208 * `saveundo`: when this option is on, undo is saved even after you close a file
209 so if you close and reopen a file, you can keep undoing
213 * `scrollmargin`: amount of lines you would like to see above and below the cursor
217 * `scrollspeed`: amount of lines to scroll for one scroll event
223 Default plugin options:
225 * `linter`: lint languages on save (supported languages are C, D, Go, Java,
226 Javascript, Lua). Provided by the `linter` plugin.
230 * `goimports`: Run goimports on save. Provided by the `go` plugin.
234 * `gofmt`: Run gofmt on save. Provided by the `go` plugin.
238 Any option you set in the editor will be saved to the file
239 ~/.config/micro/settings.json so, in effect, your configuration file will be
240 created for you. If you'd like to take your configuration with you to another
241 machine, simply copy the settings.json to the other machine.
