Keyboard macros

Keyboard macros
You are encouraged to solve this task according to the task description, using any language you may know.

Link user defined methods to user defined keys.

Such as the facility provided by emacs for key bindings.
These key bindings may be application specific or system wide.

AutoHotkey

<lang AutoHotkey> loop, 200  ;; loop 200 times while not paused { TrayTip, counting, %A_Index% press alt-p to pause sleep, 1000 }

!p::  ;; links alt-p key combination to the method pauseme() (system wide) pauseMe() return

!r::  ;; links alt-r key combination to the method resume() (system wide) resume() return

pauseMe() { Msgbox, pausing`, press alt-r to resume pause } resume() { TrayTip, resume, resuming, 2 pause, off } </lang> See ahk-viper-mode for a context sensitive vi key bindings example.

Tcl

Library: Tk

<lang tcl>package require Tk

1. Show off some emacs-like bindings...

pack [label .l -text "C-x C-s to save, C-x C-c to quit"] focus . bind . <Control-x><Control-s> {

   tk_messageBox -message "We would save here"

} bind . <Control-x><Control-c> {exit}</lang> A more direct macro-like facility would be: <lang tcl>bind . <F1> {

   foreach c [split "Macro demo!" {}] {
       event generate %W $c
   }

}</lang> This can then be wrapped up like this: <lang tcl>proc sendMacro {w string} {

   foreach c [split $string {}] {
       # Will not work for “<” character...
       event generate $w $c
   }

} proc macro {key translation} {

   bind . <$key> [list sendMacro %W [string map {% %%} $translation]]

}

1. Some demonstration macros

macro F1 "Help me!" macro F2 "You pressed the F2 key" macro F3 "I'm getting bored here..." pack [text .t]; # A place for you to test the macros</lang>

Vedit macro language

<lang vedit> // Configure a key to access menu item. // The menu item may then contain the commands directly, or it may call a macro from disk. // This has the advantage that the key binding is shown in the menu.

Key_Add("Shft-F6","[MENU]TV", OK)

// Configure a key to perform visual mode edit operations (similar to recorded key macro):

Key_Add("Numpad.Enter", "[CURSOR LEFT][LINE END][RETURN]", OK)

// Configure a key to execute macro language commands:

Key_Add("Numpad+", '[VISUAL EXIT] if(BB!=-1) { RCB(10,BB,BE) BB(-1) S("|@(10)",SET+CONFIRM) } else { S("",CONFIRM) }', OK)

// Configure a key to call a macro from disk. The old key assignment is not removed.

Key_Add("Ctrl-Shft-N",'[VISUAL EXIT] Call_File(100,"aspell.vdm","NEXT_ERROR")',INSERT+OK)

// Configure a two-key sequence (C-x C-c to save file).

Key_Add("^X C","[MENU]FS", OK)

// Remove a key assignment. If INSERT option was used when the key was assigned, the old assignment will come in effect again.

Key_Delete("Ctrl-Shft-N")

</lang>
