Options

Micro stores all of the user configuration in its configuration directory.

Micro uses the $XDG_CONFIG_HOME/micro as the configuration directory. As per the XDG spec, if $XDG_CONFIG_HOME is not set, ~/.config/micro is used as the config directory.

Here are the options that you can set:

• colorscheme: loads the colorscheme stored in $(configDir)/colorschemes/option.micro This setting is global only.

  default value: default Note that the default colorschemes (default, solarized, and solarized-tc) are not located in configDir, because they are embedded in the micro binary.

  The colorscheme can be selected from all the files in the ~/.config/micro/colorschemes/ directory. Micro comes by default with three colorschemes:

  You can read more about micro's colorschemes in the colors help topic (help colors).

• colorcolumn: if this is not set to 0, it will display a column at the specified column. This is useful if you want column 80 to be highlighted special for example.

  default value: 0

• tabsize: sets the tab size to option

  default value: 4

• indentchar: sets the indentation character

  default value:

• infobar: enables the line at the bottom of the editor where messages are printed. This option is global only.

  default value: on

• filetype: sets the filetype for the current buffer. This setting is local only

  default value: this will be automatically set depending on the file you have open

• ignorecase: perform case-insensitive searches

  default value: off

• syntax: turns syntax on or off

  default value: on

• tabstospaces: use spaces instead of tabs

  default value: off

• autoindent: when creating a new line use the same indentation as the previous line

  default value: on

• cursorline: highlight the line that the cursor is on in a different color (the color is defined by the colorscheme you are using)

  default value: on

• ruler: display line numbers

  default value: on

• statusline: display the status line at the bottom of the screen

  default value: on

• savecursor: remember where the cursor was last time the file was opened and put it there when you open the file again

  default value: off

• saveundo: when this option is on, undo is saved even after you close a file so if you close and reopen a file, you can keep undoing

  default value: off

• scrollmargin: amount of lines you would like to see above and below the cursor

  default value: 3

• scrollspeed: amount of lines to scroll for one scroll event

  default value: 2

• autosave: micro will save the buffer every 8 seconds automatically. Micro also will automatically save and quit when you exit without asking. Be careful when using this feature, because you might accidentally save a file, overwriting what was there before.

  default value: off

Default plugin options:

• linter: lint languages on save (supported languages are C, D, Go, Java, Javascript, Lua). Provided by the linter plugin.

  default value: on

• autoclose: Automatically close {} () [] "" ''. Provided by the autoclose plugin

  default value: on

• goimports: Run goimports on save. Provided by the go plugin.

  default value: off

• gofmt: Run gofmt on save. Provided by the go plugin.

  default value: on

Any option you set in the editor will be saved to the file ~/.config/micro/settings.json so, in effect, your configuration file will be created for you. If you'd like to take your configuration with you to another machine, simply copy the settings.json to the other machine.

Global and local settings

You can set these settings either globally or locally. Locally means that the setting won't be saved to ~/.config/micro/settings.json and that it will only be set in the current buffer. Setting an option globally is the default, and will set the option in all buffers.

The colorscheme option is global only, and the filetype option is local only. To set an option locally, use setlocal instead of set.

In the settings.json file you can also put set options locally by specifying a glob. Here is an example which has tabstospaces on for all files except Go files, and tabsize 4 for all files except Ruby files:

{
    "*.go": {
        "tabstospaces": false
    },
    "*.rb": {
        "tabsize": 2
    },
    "tabstospaces": true,
    "tabsize": 4
}

As you can see it is quite easy to set options locally using the settings.json file.
