Qalculate keyboard shortcut with AutoHotkey

README.md

FINALLY.

Instructions:

1. Install Qalculate
2. Install AutoHotkey
3. Add qalc.exe to your PATH. I use Rapid Environment Editor for this.
4. Run qalc.ahk

To use it:

1. Select some text, such as 1/(2*pi*10 kohm * 390 pF)
2. Press Win+Q
3. The text is replaced with the output of the calculation, such as 1 / (2 * pi * (10 * kiloohm) * (390 * picofarad)) = approx. 40.80895977 kHz

To do

• Should have separate keyboard shortcuts for including the original text or not? Like how Monster.ahk has Ctrl+Win+- for replacement, and Ctrl+Win+= for appending = and the result.

#q::
Clipboard= ; this line must be after the F12:: or it won’t get executed and the ClipWait has no effect
Send ^c
ClipWait, 1 ; put a timeout so it doesn’t get stuck if invoked with empty clipboard
if ErrorLevel ; if timeout
    return
Myclip := Clipboard
Myclip := StrReplace(Myclip, "Ω", "ohm") ; Replace ohm sign (U+2126, Ω) with ohm
Myclip := StrReplace(Myclip, "Ω", "ohm") ; Replace uppercase omega character (U+03A9, Ω) with ohm
RunWait, cmd.exe /c qalc "%Myclip%" | clip,,hide
Clipboard := RegExReplace(Clipboard, "\R", "") ; Remove newline characters from the result
Send % Myclip " = " Clipboard
Sleep, 500 ; must wait to give time to paste before clearing clipboard
Clipboard=
return ; really should have this, especially if other code follows
