Use TCC and AutoHotKey to do the math from a text editor

[Joe Caverly]

First off,
there are of course better ways to do math from a text editor.

This was just an exercise,
to see if it could be done.

When I am in my text editor, I type;

164.54 - 124.45 .calc

The .calc activates the AutoHotKey code,

• highlighting the mathematical expression
• copying it to the clipboard
• switching to TCC.EXE
• typing a :
• pasting the mathematical expression from the clipboard
• pressing the Ctrl-Enter keyboard combination
• which copies the answer to the clipboard
• switch back to my text editor
• and then over-write the highlighted mathematical expression with the answer.
  

; AutoHotkey v2 - use .calc to evaluate via Take Command (tcc.exe)
; Requires CMath from the EditKeys Plugin 
; https://charlesdye.net/plugins/editkeys.html
;
; I use RightNote as my text editor
; https://www.bauerapps.com/rightnote/
:*:.calc::
{
    ; Only run inside RightNote
    if !WinActive("ahk_exe RightNote.exe")
        return

    ; Remove the typed trigger ".calc"
    Send("{Backspace}")
    Sleep 60

    ; Select from cursor to start of the line
    Send("{Shift down}{Home}{Shift up}")
    Sleep 60

    Send("^c")
    
    tccWin := WinExist("ahk_exe tcc.exe")
        
    WinActivate(tccWin)
    
    Sleep 100
    
    ; Type ":" then Shift+Insert to paste, then Ctrl+Enter to evaluate
    Send(":")
    Sleep 40
    Send("{Shift down}{Insert}{Shift up}") 
    Sleep 40 
    Send("{Ctrl down}{Enter}{Ctrl up}")
    
    Sleep 100
    
    WinActivate("ahk_exe RightNote.exe") 
    WinWaitActive("ahk_exe RightNote.exe", 2) 
    Sleep 80 ; Paste the result (replaces the highlighted expression) 
    Send("^v")
}

I'm not checking to make sure that tcc.exe is available,
nor am I doing much error checking at all.

As I said,
This was just an exercise,
to see if it could be done.
