AutoHotkey Speed Tips

A Collection of Techniques for Speeding Up Your AutoHotkey Scripts

I recently received the follow message from an AutoHotkey user perusing my blogs:

Jack, you can’t post false statements like this:

“However, the ternary does not provide better performance than the traditional If-Then-Else statement format.”

The ternary operator is inarguably faster than if/else and I encourage you to try this yourself.

I recently switched the core logic of my JSON parser from If/Else to ternary and saw an incredible speed increase. To the point where I only use If/If Else/Else statements when absolutely necessary (Ex: If I must have a loop in the middle of a check).

You can code entire blocks using nothing but ternary as long as you use proper parentheses, commas, and function calls.

There is a very well done AHK forum post that covers script optimizations and they report that ternary performs FORTY PERCENT FASTER than if/else statements.

Not sure if hyperlinks are allowed in these comments, so instead I’ll advise googling “AHK How to optimize the speed of a script as much as possible.” The first result should be the article in question. Pages 1 and 4 have tons of script speed gold in them.

I hope you’ll consider correcting/updating this article.

Comment on “AutoHotkey Toggles and the Ternary Operator”

I wrote that blog five years ago and I don’t know that I was talking about performance speed. I think I was referring to how the two expressions operate. In any case, I used a poor choice of words and have drawn a line through the comment.

AutoHotkey Tip of the Week: Capture Web Page Addresses (URLs)

When Browsing the Web This Special Function Copies the Page URL without Any Extra Effort

Normally, you can find a Web page address in the URL bar at the top of the browser. Click in that address field and copy it with CTRL+C. That simple act may make the subject of this blog look redundant. However, when applied to last week’s CopyRegTagWin.ahk script, the GetActiveBrowserURL() function can save numerous keystrokes.

By using the user-defined GetActiveBrowserURL() function, a modified version of the CopyRefTagWin.ahk script can include both the title of the source window and, if from a Web page, its URL. If collecting data for research, this feature makes reconstructing sources much easier—without any extra effort. Continue reading

AutoHotkey Tip of the Week: Channeling Text to a Tagged Window

When Collecting Information from Various Sources, Send the Text Directly to an Unseen Text Editing Field

Last time in “Tricks for Tracking and Activating Target Process Windows“, I demonstrated a technique for tagging and tracking a window using its Unique ID. After tagging any window with one Hotkey combination, you can instantly recall it with another. While a pretty cool trick, the question of when would you ever use it arises. This time I offer a practical tool for gathering information from various digital sources (Web pages, documents, e-books, etc.) into one text editor window—without jumping back-and-forth while doing cut-and-paste operations.
