AutoHotkey Tip of the Week: The Eval() Function for Hotkey Math Calculations and Text Manipulation

The Classic Eval() Function Solves Problems You Didn’t Even Know You Had by Calculating and Resolving AutoHotkey Functions and Expressions Found in Text Strings!

When I work on particular AutoHotkey solutions, often I find myself in the middle of a treasure hunt—picking up hidden gems along the way. Although operative for years, I didn’t know these valuable tools existed until I went searching for answers to a seemingly unrelated problem.

EvalfunctionMsgBox2For example, the simple question about capitalizing sentences led me to the RegExHotstrings() function discussed last time. As I dug deeper into the math-side of dynamic Hotstrings, I discovered the Eval() function. While many old AutoHotkey hands have employed the Eval() function for years, I didn’t understand its power until I used it in the investigation. (Even now the Eval() function does way more than I comprehend. I’ve only scratched the surface of its capabilities.) Continue reading

AutoHotkey Tip of the Week: Dynamic Regular Expressions (RegEx) for Math Calculating Hotstrings

An AutoHotkey Classic, the Dynamic Hotstrings() Function Makes Instant RegEx Replacements Possible—Now, You Can Do Math with Your Hotstrings!

Anyone who reads my blog on a routine basis knows how I love Regular Expressions (RegEx). They make feasible all kinds of capabilities not practical by any other method. While not necessarily easy for a beginner to grasp, RegEx provides a mechanism for matching text when you don’t know exactly which characters you need (wildcards). (That’s why I wrote the book A Beginner’s Guide to Using Regular Expressions in AutoHotkey.) Although you may encounter a bit of a learning curve, RegEx gives you the ability to accomplish some pretty fancy tasks. This time I plan to demonstrate a couple of Hotstring techniques that might amaze you—they did me! Continue reading

Quick Tip: Using the Sleep Command with Clipboard Routines

Use the Sleep Command to Debug Intermittent Routines

tipsLast night, I received the following comment from Thom Blake about last week’s blog “Auto-Capitalize the First Letter of Sentences” prompting this Quick Tip about adding the Sleep command at critical points in certain types of AutoHotkey routines:

Jack

Great script but I seem to have a problem with the capitalize a word function. It only works intermittently. The message box says “No text selected!” when clearly there is.

Thanks, Thom!

This is a needed reminder about a common problem when using the Send command with the Clipboard routine. Sometimes, for whatever reason, certain commands execute before the completion of the last action. In this case, AutoHotkey attempts to copy text to the Windows Clipboard before the SendInput text selection action completes: Continue reading

AutoHotkey Tip of the Week: Auto-Capitalize the First Letter of Sentences

Some People Don’t Find It Easy to Shift to Uppercase While Capitalizing Words—AutoHotkey Allows Us to Stop Reaching for the Shift Key—at Least for New Sentences!

I received the following question from a reader:

Hello,

Is there a script to auto-capitalize the first word of a sentence. Or after a period?

Thanks.

*          *          *

Not everyone received an A in typing class—I didn’t. Plus, many people for a variety of reasons may find navigating a keyboard difficult. Where using the Shift key may be a simple inconvenience for some, people who are not blessed with full functioning fingers and/or hands encounter an arduous task. Even capitalizing the word “I” (“i think i will go”) can present a challenge. The primary goal of AutoHotkey is to make your Windows life easier. Continue reading

AutoHotkey Tip of the Week: Use Regular Expressions (RegEx) to Convert Repetitious AutoHotkey Code

Regular Expressions (RegEx) Can Simplify a Tedious Code Reformatting Problem

Recently, I received the following comment from Thom:

Greetings,

A small improvement to the Autocorrect AHK script. I have been using this script for years and find it very useful. I was always a bit intrigued about the section of ambiguous entries which was commented out and not much use.

I was fascinated to read about your TextMenu function [found in the book Beginning AutoHotkey Hotstrings] to display the various choices. I found a simple way with RegEx to change all the entries in the section.

For example:

::electon::election, electron

To:

::electon::
  TextMenu("election, electron")
Return

I copied and pasted the list into Notepad++ and then ran this find-and-replace.

Find:

(::\w+::)(.+)

Replace:

$1\n TextMenu\(\"$2\"\)\nReturn

And presto it works—some entries need tweaking but it works well. Continue reading

AutoHotkey Tip of the Week: Increase the Flexibility of Menus by Passing Data with the BoundFunc Object

Streamline and Add Power to Hotstring Menus by Binding Action Parameters Directly to Each Menu Item

*          *          *

If you use AutoHotkey menus, then you may find this blog the most useful menu tip yet. At first, using the BoundFunc Object to pass data may seem confusing, but, once understood, it opens up many more opportunities for taking advantage of menus in your AutoHotkey scripts.

*          *          *

HotstringSubMenus

As often happens when working on an AutoHotkey script, a deeper understanding of the available tools completely changes the direction of the project. While all of the Menu tricks I’ve offered in the past HotstringMenu.ahk scripts still work (and you may want to continue using many of those techniques), the following approach which combines arrays, the variadic function parameter, and the boundfunc object creates a cleaner, more functional structure for generating Hotstring replacement menus. In short, implementing the boundfunc object allows me to drop many of those previous menu tricks and build menus using virtually any menu item format without regard for their later use through the value of the A_ThisMenuItem variable.

AutoHotkey Tip of the Week: Fold Long AutoHotkey Menus into Columns

Sometimes We Resort to Programming Trickery to Make Autohotkey Menus Look Better

The Windows Menu control is part of the Windows operating system. AutoHotkey offers you the Menu command for setting up and altering custom menus using this built-in control. However, much of the inflexibility of AutoHotkey menus results from the limitations of the Windows Menu object itself. This rigidity often forces us to resort to programming sleight-of-hand to accomplish many goals. Continue reading
