AHK: Visualizing ELSE/IF with Arrays

So Hopper’s Amazing Decipherer Script 1.0 was about 472 lines because it included ELSE IF clauses for every letter in the alphabet.

HADS 2.0 cuts it down to 77 lines because arrays, as it turns out, are incredibly useful when paired with loops.

Making a Rotated Alphabet

Deciphering a Caesar cipher requires that the alphabet be moved up by a certain number. Like so.


Notice that this is basically a 2-step process. Turn the letters of the alphabet into numbers 1-26. Then add the rotational value to each of them to find their new positions, in the code below that’s assigned to a variable called indexVar. In ROT1, A =1 and the rotational value is 1, so A = 1+1 = 2.

But what happens when you hit Z? Z=26 and the rotation is 1, so Z =  26+1 = 27.

So, you want to tell the computer IF the number goes above 27, then you want to reset it to 1 and continue.

AHK: How To Delete Every Other File in a Folder

STEP 1: Make a new AutoHotkey file. Not sure how to do that? Click here.

STEP 2: Right click your new AutoHotKey Script → Edit Script.

STEP 3: Copy and paste this text into the body.

Var = 8071
Loop, 100
FileDelete, C:\Users\Desktop\Sentient Webcam\IMG_%Var%.jpg

STEP 4: Go to the folder with all the files in it, and copy the file path so the computer knows where to look. Paste that in place of the red text in the script.
