! Configuration
Configuration for the ~CodeMirror text-editor can be done from within the CodeMirror Settings Tab in the [[ControlPanel|$:/ControlPanel]] (Settings - ~CodeMirror)
!!Setting a different Theme
~CodeMirror themes are available in the [ext[official GitHub repository|https://github.com/codemirror/CodeMirror/tree/master/theme]]
More themes can be found at https://github.com/FarhadG/code-mirror-themes/tree/master/themes and previewed [ext[here|http://farhadg.github.io/code-mirror-themes/]]
To add a theme to your wiki, follow these four steps:
* choose one of the CSS files and copy its content to a new tiddler
* remove all comments from the top and tag the tiddler with <<tag-pill "$:/tags/Stylesheet">>
* add a field "module-type" with the value "codemirror-theme". add a field "name" with the exact ''name'' of the theme as value
* save the tiddler and go to the Settings tab in $:/ControlPanel - look for the "theme" dropdown to select your newly added theme
!!Line Numbers
To show or hide the Line Numbers at the left, go to ~ControlPanel - Settings - ~CodeMirror and look for the "Line Numbers" checkbox
!!Line Wrapping
Controls if long lines get visually wrapped to a new line if they're too long to fit the editor width or if the editor should scroll horizontally
To change the line-wrapping behaviour, go to ~ControlPanel - Settings - ~CodeMirror and look for the "Line Wrapping" checkbox
!!Show Cursor when selecting
Defines whether the Mouse cursor should be visually shown or hidden when making a text-selection
To change the show-cursor-when-selecting behaviour, go to ~ControlPanel - Settings - ~CodeMirror and look for the "Show cursor when selecting" checkbox
!!~CodeMirror Font Family
The Font-Family used within the ~CodeMirror text-editor defaults to "monospace" which will choose your configured monospace system-font
That setting can be overridden entering one or more Font-Families in the "Font Family" input field at ~ControlPanel - Settings - ~CodeMirror
* The entries must be separated by semicolons ','
* Font-Family Names that contain spaces must be quoted like "My Font"
* If a list of Font-Families is specified, the last Font-Family found on the user-system gets used, non-existing fonts get ignored
* If none of the specified Font-Families is available, ~CodeMirror uses the default "monospace"
!!"Hidden" Settings:
