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 * `eofnewline`: micro will automatically add a newline to the end of the file
57 default value: `false`
59 * `fastdirty`: this determines what kind of algorithm micro uses to determine if
60 a buffer is modified or not. When `fastdirty` is on, micro just uses a
61 boolean `modified` that is set to `true` as soon as the user makes an edit.
62 This is fast, but can be inaccurate. If `fastdirty` is off, then micro will
63 hash the current buffer against a hash of the original file (created when the
64 buffer was loaded). This is more accurate but obviously more resource
65 intensive. This option is only for people who really care about having
66 accurate modified status.
70 * `fileformat`: this determines what kind of line endings micro will use for the
71 file. UNIX line endings are just `\n` (linefeed) whereas dos line endings are
72 `\r\n` (carriage return + linefeed). The two possible values for this option
73 are `unix` and `dos`. The fileformat will be automatically detected (when you
74 open an existing file) and displayed on the statusline, but this option is
75 useful if you would like to change the line endings or if you are starting a
80 * `filetype`: sets the filetype for the current buffer. This setting is
83 default value: this will be automatically set depending on the file you have
86 * `ignorecase`: perform case-insensitive searches.
88 default value: `false`
90 * `indentchar`: sets the indentation character.
92 default value: ` ` (space)
94 * `infobar`: enables the line at the bottom of the editor where messages are
95 printed. This option is `global only`.
99 * `keepautoindent`: when using autoindent, whitespace is added for you. This
100 option determines if when you move to the next line without any insertions
101 the whitespace that was added should be deleted to remove trailing whitespace.
102 By default, the autoindent whitespace is deleted if the line was left empty.
104 default value: `false`
106 * `keymenu`: display the nano-style key menu at the bottom of the screen. Note
107 that ToggleKeyMenu is bound to `Alt-g` by default and this is displayed in
108 the statusline. To disable this, simply by `Alt-g` to `UnbindKey`.
110 default value: `false`
112 * `mouse`: whether to enable mouse support. When mouse support is disabled,
113 usually the terminal will be able to access mouse events which can be useful
114 if you want to copy from the terminal instead of from micro (if over ssh for
115 example, because the terminal has access to the local clipboard and micro
118 default value: `true`
120 * `pluginchannels`: contains all the channels micro's plugin manager will search
121 for plugins in. A channel is simply a list of 'repository' json files which
122 contain metadata about the given plugin. See the `Plugin Manager` section of
123 the `plugins` help topic for more information.
125 default value: `https://github.com/micro-editor/plugin-channel`
127 * `pluginrepos`: contains all the 'repositories' micro's plugin manager will
128 search for plugins in. A repository consists of a `repo.json` file which
129 contains metadata for a single plugin.
133 * `rmtrailingws`: micro will automatically trim trailing whitespaces at eol.
135 default value: `false`
137 * `ruler`: display line numbers.
139 default value: `true`
141 * `savecursor`: remember where the cursor was last time the file was opened and
142 put it there when you open the file again.
144 default value: `false`
146 * `savehistory`: remember command history between closing and re-opening
149 default value: `true`
151 * `saveundo`: when this option is on, undo is saved even after you close a file
152 so if you close and reopen a file, you can keep undoing.
154 default value: `false`
156 * `scrollbar`: display a scroll bar
158 default value: `false`
160 * `scrollmargin`: amount of lines you would like to see above and below the
165 * `scrollspeed`: amount of lines to scroll for one scroll event.
169 * `smartpaste`: should micro add leading whitespace when pasting multiple lines?
170 This will attempt to preserve the current indentation level when pasting an
173 default value: `true`
175 * `softwrap`: should micro wrap lines that are too long to fit on the screen.
177 default value: `false`
179 * `splitbottom`: when a horizontal split is created, should it be created below
182 default value: `true`
184 * `splitright`: when a vertical split is created, should it be created to the
185 right of the current split?
187 default value: `true`
189 * `statusline`: display the status line at the bottom of the screen.
191 default value: `true`
193 * `matchbrace`: highlight matching braces for '()', '{}', '[]'
195 default value: `false`
197 * `matchbraceleft`: when matching a closing brace, should matching match the
198 brace directly under the cursor, or the character to the left? only matters
199 if `matchbrace` is true
201 default value: `false`
203 * `syntax`: turns syntax highlighting on or off.
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 * `tabmovement`: navigate spaces at the beginning of lines as if they are tabs
214 (e.g. move over 4 spaces at once). This option only does anything if
215 `tabstospaces` is on.
217 default value: `false`
219 * `tabsize`: sets the tab size to `option`
223 * `tabstospaces`: use spaces instead of tabs
225 default value: `false`
227 * `termtitle`: defines whether or not your terminal's title will be set by micro
230 default value: `false`
232 * `useprimary` (only useful on *nix): defines whether or not micro will use the
233 primary clipboard to copy selections in the background. This does not affect
234 the normal clipboard using Ctrl-C and Ctrl-V.
236 default value: `true`
240 Default plugin options:
242 * `autoclose`: automatically close `{}` `()` `[]` `""` `''`. Provided by the
245 default value: `true`
247 * `ftoptions`: by default, micro will set some options based on the filetype. At
248 the moment, micro will use tabs for makefiles and spaces for python and yaml
249 files regardless of your settings. If you would like to disable this behavior
250 turn this option off.
252 default value: `true`
254 * `linter`: Automatically lint when the file is saved. Provided by the `linter`
257 default value: `true`
259 Any option you set in the editor will be saved to the file
260 ~/.config/micro/settings.json so, in effect, your configuration file will be
261 created for you. If you'd like to take your configuration with you to another
262 machine, simply copy the settings.json to the other machine.
265 ## Global and local settings
267 You can set these settings either globally or locally. Locally means that the
268 setting won't be saved to `~/.config/micro/settings.json` and that it will only
269 be set in the current buffer. Setting an option globally is the default, and
270 will set the option in all buffers.
272 The `colorscheme` option is global only, and the `filetype` option is local
273 only. To set an option locally, use `setlocal` instead of `set`.
275 In the `settings.json` file you can also put set options locally by specifying either
276 a glob or a filetype. Here is an example which has `tabstospaces` on for all files except Go
277 files, and `tabsize` 4 for all files except Ruby files:
282 "tabstospaces": false
287 "tabstospaces": true,
292 Or similarly you can match with globs:
297 "tabstospaces": false
302 "tabstospaces": true,
