Eval - Evaluate Expressions in Strings Dynamically (Updated Dec, 28, 2020)

[Pulover]

Update: v1.1.7

• Fixed bug when assigning a variable to a ternary operation.

[guest3456]

for reference, AHK_H can do Eval() stuff built-in:

Code: Select all

var := 99
MsgBox var=%var%

mycode := "var2 := var+2`nMsgBox, var2 from within ahkExec = `%var2`%"
MsgBox, mycode to dynamically execute:`n`n%mycode%

ahkExec(mycode)

MsgBox, var2 from main script = %var2%

ahkExec() is one function provided to allow it, i think there are a few others for doing it in separate threads

This Eval Function is great! but apparently I found some bug where some results are wrong

eg.
using the "expression tester.ahk". I tried evaluating:
-(2.6167)-193

the result generated was:
195.616700

the answer should be:
-195.616700

It will be a good news if there is a solution for this probem.

• Fixing bugs with subtraction.

Another attempt to fix the problems with negative numbers in math operations. This time instead of trying to fix the compiled expression I've removed one line of the compiler that was causing the issue, so if anyone finds another problem because of this change, please let me know because I have no idea what that line was supposed to do...

Rodolfo - great work. I just discovered this via Jack's AutoHotkey Blog. This will save me heaps of time. I'm not sure how to get it to work with percentages though.

[Pulover]

Thanks. What do you mean by get it to work with percentages? It should be able to deal with any math expression as if it was in ahk script. If you've found an inconsistency you can report the issue at github.
