* Supported keybindings:
|
|
*
|
|
* Motion:
|
|
* h, j, k, l
|
|
* gj, gk
|
|
* e, E, w, W, b, B, ge, gE
|
|
* f<character>, F<character>, t<character>, T<character>
|
|
* $, ^, 0, -, +, _
|
|
* gg, G
|
|
* %
|
|
* '<character>, `<character>
|
|
*
|
|
* Operator:
|
|
* d, y, c
|
|
* dd, yy, cc
|
|
* g~, g~g~
|
|
* >, <, >>, <<
|
|
*
|
|
* Operator-Motion:
|
|
* x, X, D, Y, C, ~
|
|
*
|
|
* Action:
|
|
* a, i, s, A, I, S, o, O
|
|
* zz, z., z<CR>, zt, zb, z-
|
|
* J
|
|
* u, Ctrl-r
|
|
* m<character>
|
|
* r<character>
|
|
*
|
|
* Modes:
|
|
* ESC - leave insert mode, visual mode, and clear input state.
|
|
* Ctrl-[, Ctrl-c - same as ESC.
|
|
*
|
|
* Registers: unnamed, -, a-z, A-Z, 0-9
|
|
* (Does not respect the special case for number registers when delete
|
|
* operator is made with these commands: %, (, ), , /, ?, n, N, {, } )
|
|
* TODO: Implement the remaining registers.
|
|
* Marks: a-z, A-Z, and 0-9
|
|
* TODO: Implement the remaining special marks. They have more complex
|
|
* behavior.
|
|
*
|
|
* Events:
|
|
* 'vim-mode-change' - raised on the editor anytime the current mode changes,
|
|
* Event object: {mode: "visual", subMode: "linewise"}
|
|
*
|
|
* Code structure:
|
|
* 1. Default keymap
|
|
* 2. Variable declarations and short basic helpers
|
|
* 3. Instance (External API) implementation
|
|
* 4. Internal state tracking objects (input state, counter) implementation
|
|
* and instanstiation
|
|
* 5. Key handler (the main command dispatcher) implementation
|
|
* 6. Motion, operator, and action implementations
|
|
* 7. Helper functions for the key handler, motions, operators, and actions
|
|
* 8. Set up Vim to work as a keymap for CodeMirror.
