3 Micro stores all of the user configuration in its configuration directory.
5 Micro uses the `$XDG_CONFIG_HOME/micro` as the configuration directory. As per
6 the XDG spec, if `$XDG_CONFIG_HOME` is not set, `~/.config/micro` is used as
9 Here are the options that you can set:
11 * `autoindent`: when creating a new line, use the same indentation as the
16 * `autosave`: micro will save the buffer every 8 seconds automatically. Micro
17 also will automatically save and quit when you exit without asking. Be
18 careful when using this feature, because you might accidentally save a file,
19 overwriting what was there before.
21 default value: `false`
23 * `basename`: in the infobar, show only the basename of the file being edited
24 rather than the full path.
26 default value: `false`
28 * `colorcolumn`: if this is not set to 0, it will display a column at the
29 specified column. This is useful if you want column 80 to be highlighted
34 * `colorscheme`: loads the colorscheme stored in
35 $(configDir)/colorschemes/`option`.micro, This setting is `global only`.
37 default value: `default`
39 Note that the default colorschemes (default, solarized, and solarized-tc)
40 are not located in configDir, because they are embedded in the micro binary.
42 The colorscheme can be selected from all the files in the
43 ~/.config/micro/colorschemes/ directory. Micro comes by default with three
46 You can read more about micro's colorschemes in the `colors` help topic
49 * `cursorline`: highlight the line that the cursor is on in a different color
50 (the color is defined by the colorscheme you are using).
54 * `encoding`: the encoding to open and save files with. Supported encodings
55 are listed at https://www.w3.org/TR/encoding/.
57 default value: `utf-8`
59 * `eofnewline`: micro will automatically add a newline to the file.
61 default value: `false`
63 * `fastdirty`: this determines what kind of algorithm micro uses to determine if
64 a buffer is modified or not. When `fastdirty` is on, micro just uses a
65 boolean `modified` that is set to `true` as soon as the user makes an edit.
66 This is fast, but can be inaccurate. If `fastdirty` is off, then micro will
67 hash the current buffer against a hash of the original file (created when the
68 buffer was loaded). This is more accurate but obviously more resource
69 intensive. This option is only for people who really care about having
70 accurate modified status.
74 * `fileformat`: this determines what kind of line endings micro will use for the
75 file. UNIX line endings are just `\n` (linefeed) whereas dos line endings are
76 `\r\n` (carriage return + linefeed). The two possible values for this option
77 are `unix` and `dos`. The fileformat will be automatically detected (when you
78 open an existing file) and displayed on the statusline, but this option is
79 useful if you would like to change the line endings or if you are starting a
84 * `filetype`: sets the filetype for the current buffer. This setting is
87 default value: this will be automatically set depending on the file you have
90 * `ignorecase`: perform case-insensitive searches.
92 default value: `false`
94 * `indentchar`: sets the indentation character.
96 default value: ` ` (space)
98 * `infobar`: enables the line at the bottom of the editor where messages are
99 printed. This option is `global only`.
101 default value: `true`
103 * `keepautoindent`: when using autoindent, whitespace is added for you. This
104 option determines if when you move to the next line without any insertions
105 the whitespace that was added should be deleted to remove trailing whitespace.
106 By default, the autoindent whitespace is deleted if the line was left empty.
108 default value: `false`
110 * `keymenu`: display the nano-style key menu at the bottom of the screen. Note
111 that ToggleKeyMenu is bound to `Alt-g` by default and this is displayed in
112 the statusline. To disable this, simply by `Alt-g` to `UnbindKey`.
114 default value: `false`
116 * `matchbrace`: highlight matching braces for '()', '{}', '[]'
118 default value: `false`
120 * `matchbraceleft`: when matching a closing brace, should matching match the
121 brace directly under the cursor, or the character to the left? only matters
122 if `matchbrace` is true
124 default value: `false`
126 * `mouse`: whether to enable mouse support. When mouse support is disabled,
127 usually the terminal will be able to access mouse events which can be useful
128 if you want to copy from the terminal instead of from micro (if over ssh for
129 example, because the terminal has access to the local clipboard and micro
132 default value: `true`
134 * `pluginchannels`: contains all the channels micro's plugin manager will search
135 for plugins in. A channel is simply a list of 'repository' json files which
136 contain metadata about the given plugin. See the `Plugin Manager` section of
137 the `plugins` help topic for more information.
139 default value: `https://github.com/micro-editor/plugin-channel`
141 * `pluginrepos`: contains all the 'repositories' micro's plugin manager will
142 search for plugins in. A repository consists of a `repo.json` file which
143 contains metadata for a single plugin.
147 * `rmtrailingws`: micro will automatically trim trailing whitespaces at eol.
149 default value: `false`
151 * `ruler`: display line numbers.
153 default value: `true`
155 * `savecursor`: remember where the cursor was last time the file was opened and
156 put it there when you open the file again.
158 default value: `false`
160 * `savehistory`: remember command history between closing and re-opening
163 default value: `true`
165 * `saveundo`: when this option is on, undo is saved even after you close a file
166 so if you close and reopen a file, you can keep undoing.
168 default value: `false`
170 * `scrollbar`: display a scroll bar
172 default value: `false`
174 * `scrollmargin`: amount of lines you would like to see above and below the
179 * `scrollspeed`: amount of lines to scroll for one scroll event.
183 * `smartpaste`: should micro add leading whitespace when pasting multiple lines?
184 This will attempt to preserve the current indentation level when pasting an
187 default value: `true`
189 * `softwrap`: should micro wrap lines that are too long to fit on the screen.
191 default value: `false`
193 * `splitbottom`: when a horizontal split is created, should it be created below
196 default value: `true`
198 * `splitright`: when a vertical split is created, should it be created to the
199 right of the current split?
201 default value: `true`
203 * `statusline`: display the status line at the bottom of the screen.
205 default value: `true`
207 * `sucmd`: specifies the super user command. On most systems this is "sudo" but
208 on BSD it can be "doas." This option can be customized and is only used when
211 default value: `sudo`
213 * `syntax`: turns syntax on or off.
215 default value: `true`
217 * `tabmovement`: navigate spaces at the beginning of lines as if they are tabs
218 (e.g. move over 4 spaces at once). This option only does anything if
219 `tabstospaces` is on.
221 default value: `false`
223 * `tabsize`: sets the tab size to `option`
227 * `tabstospaces`: use spaces instead of tabs
229 default value: `false`
231 * `termtitle`: defines whether or not your terminal's title will be set by micro
234 default value: `false`
236 * `useprimary` (only useful on *nix): defines whether or not micro will use the
237 primary clipboard to copy selections in the background. This does not affect
238 the normal clipboard using Ctrl-C and Ctrl-V.
240 default value: `true`
244 Default plugin options:
246 * `autoclose`: automatically close `{}` `()` `[]` `""` `''`. Provided by the
249 default value: `true`
251 * `ftoptions`: by default, micro will set some options based on the filetype. At
252 the moment, micro will use tabs for makefiles and spaces for python and yaml
253 files regardless of your settings. If you would like to disable this behavior
254 turn this option off.
256 default value: `true`
258 * `linter`: Automatically lint when the file is saved. Provided by the `linter`
261 default value: `true`
263 Any option you set in the editor will be saved to the file
264 ~/.config/micro/settings.json so, in effect, your configuration file will be
265 created for you. If you'd like to take your configuration with you to another
266 machine, simply copy the settings.json to the other machine.
269 ## Global and local settings
271 You can set these settings either globally or locally. Locally means that the
272 setting won't be saved to `~/.config/micro/settings.json` and that it will only
273 be set in the current buffer. Setting an option globally is the default, and
274 will set the option in all buffers.
276 The `colorscheme` option is global only, and the `filetype` option is local
277 only. To set an option locally, use `setlocal` instead of `set`.
279 In the `settings.json` file you can also put set options locally by specifying either
280 a glob or a filetype. Here is an example which has `tabstospaces` on for all files except Go
281 files, and `tabsize` 4 for all files except Ruby files:
286 "tabstospaces": false
291 "tabstospaces": true,
296 Or similarly you can match with globs:
301 "tabstospaces": false
306 "tabstospaces": true,
