Update: Switched to generic ve.ui.Toolbar and ve.ui.Tool for consistency
with VE in general. Changed searchbox to floating and hidden by default.
Call for search using shortcut key. Overriden ESC key.
Node handler for <syntaxhighlight>'s Rdfa type.
Embedded in VisualEditor.php with its own ResourceLoader module.
Use $wgVisualEditorEnableExperimentalCode in LocalSettings.php
to load the module.
Supported languages (for testing): text, javascript
Features:
(1) Internal mechanisms:
(1.1) Tokenizer. Tokenize input code string.
(1.2) Highlighter. Highlight based on predefined rules.
(1.3) Syntax checker. Validate based on predefined rules.
(2) SimpleSurface:
(2.1) Auto indenter. Works with (){}[] blocks.
(2.2) Reformatter. Reformats spaces and remove trailing
whitespaces.
(2.3) Language selection dropdown.
(2.4) Basic editing. Insert, deletion, selection.
(2.5) Clipboard & edit history support.
(2.5.1) Undo (Ctrl + Z), redo (Ctrl + Y)
(2.5.2) Copy (Ctrl + C), cut (Ctrl + X), paste (Ctrl + V)
(2.6) Search & replace. Ctrl + F to quickly move focus to search
box.
