VimIMContext

Vim emulation.

The GtkSourceVimIMContext is a class@Gtk.IMContext implementation that can be used to provide Vim-like editing controls within a class@View.

The GtkSourceViMIMContext will process incoming class@Gdk.KeyEvent as the user types. It should be used in conjunction with a class@Gtk.EventControllerKey.

Various features supported by GtkSourceVimIMContext include:

• Normal, Insert, Replace, Visual, and Visual Line modes

• Support for an integrated command bar and current command preview

• Search and replace

• Motions and Text Objects

• History replay

• Jumplists within the current file

• Registers including the system and primary clipboards

• Creation and motion to marks

• Some commonly used Vim commands

It is recommended that applications display the contents of property@VimIMContext:command-bar-text and property@VimIMContext:command-text to the user as they represent the command-bar and current command preview found in Vim.

GtkSourceVimIMContext attempts to work with additional class@Gtk.IMContext implementations such as IBus by querying the class@Gtk.TextView before processing the command in states which support it (notably Insert and Replace modes).
