AutoHotkey Tip of the Week: Embed Images Directly in the AHK Script

Rather than Use the FileInstall AutoHotkey Command, This Trick Allows You to Lodge Images Directly into Your AutoHotkey Scripts

Light Bulb!In the past, whenever I wanted to add a graphic image to an AutoHotkey script, I needed to either separately provided the file or embed it in the compiled EXE file using the FileInstall command. The AutoHotkey world has opened my eyes to an ancient technique for embedding an image directly in the AHK script—no need to supply the file separately or embed it by compiling the script.

AutoHotkey Tip of the Week: Add Power to Any Command with Forced Expressions (%)—October 7, 2019

Use the Forced Expression Operator (%) to Adapt AutoHotkey Commands On-the-Fly

Light Bulb!Most AutoHotkey Version 1.1 commands use plain text as parameters. That means AutoHotkey interprets the text exactly as written—no quotes needed and no variables accepted. In version 1.1, this would limit the commands except for the availability of the traditional (or legacy) double-quote text replacement operator (%var%).

The %var% technique allows us to substitute any variable directly into an AutoHotkey command. However, using the forced expression operator (%) adds even greater flexibility and power to almost any AutoHotkey code. In many cases, rather than developing complicated subroutines, you can use this technique to embed expressions and functions directly into version 1.1 AutoHotkey commands. Continue reading

AutoHotkey Tip of the Week: Add Temporary Hotkeys to MsgBox Windows—September 23, 2019

Isolate Hotkeys to Only Operate for an Open or Active Window

In the Weekly Tip, “IfWinActive Versus #IfWinActive“, I recommended isolating Hotkeys to specific windows. This time I offer a practical example.

hotkeycover200For more information, see “Chapter Two: Block Windows Shortcuts with AutoHotkey” and “Chapter Three: AutoHotkey #Directives for Context-Sensitive Hotkeys—#IfWinActive” of the book AutoHotkey Hotkey Tips, Tricks, and Techniques.

The #IfWinExist directive offers a number of advantages when creating temporary Hotkeys:

  1. The Hotkeys activate only when AutoHotkey opens the controlling window.
  2. If other conflicting Hotkeys exist, the temporary Hotkeys take precedence as long as the window exists.
  3. After closing the controlling window, the Hotkeys deactivate minimizing interference with other possible Hotkeys or shortcuts.

AutoHotkey Tip of the Week: Auto-Swap Transposed Letters—September 9, 2019

Tip: Fix Reversed Letter Typos with this Simple Hotkey Trick

Place the cursor between two letters and hit the Alt+R Hotkey combination. The letters reverse positions.

Light Bulb!I use this Hotkey whenever my mild dyslexia kicks in and leaves me with swapped letters. My AutoHotkey AutoCorrect.ahk script may catch many such errors but many more make it on to my computer screen. I could have written a Hotkey routine which swapped pre-selected (highlighted) letters, but, rather than taking the time to select the characters by dragging the mouse across them, I wanted to merely place the cursor between the two errant letters.

This use of the Send command makes it incredibly easy to transpose any two letters. Simply place the cursor between them and hit ALT+R (as shown in the figure.)

AutoHotkey Tip of the Week: Instant Upper Case, Lower Case, and Initial Cap Text—September 2, 2019

Tips: Quick Hotkeys for Changing Text To/From Capital Letters and How to Initial Cap Everything, Plus, How to Write Robust Clipboard Routines

Light Bulb!This week I offer two useful tips: one for editing text and the other for improving your AutoHotkey scripts.

When reviewing my books, I look for those tips which I use all the time. I’ve found that I developed some scripts primarily for demonstration purposes and rarely ever use them again. Yet, I have a few which I use so much that I feel like they have become a part of my Windows system.

AHKNewCover200In this case, while perusing my Beginner’s Guide to AutoHotkey, I noticed in “Chapter Four: Hotkeys and Text Editing with Windows Clipboard” the Hotkeys for changing selected portions of text into all capital letters, all lowercase letters, or initial cap every word in the section. I originally wrote these Hotkeys when I edited articles submitted by freelance writers.

Some writers have a penchant for placing their article headlines and topic subheadings in all uppercase letters. By creating a Hotkey for converting the entire line to Title Mode (initial capital letter for each word), I quickly solved the retyping problem:

Total the Numbers Found in Any Document (AutoHotkey RegEx Tips Part 5)

For a Quick-and-Dirty Calculator, Use Regular Expressions (RegEx) to Pull Numbers from Documents or Web Pages and Total Them Up—Plus, a RegEx for Removing (or Extracting) Numeric IP Addresses

Shifting gears, I end the discussion of the MultiPaste.ahk script which parses copied data into component parts for easier paste operations into other documents. With this blog, I start working on another tool for simplifying a Windows task—addition.

Sometimes I see a list of numbers in either a document or a Web page which I would like to quickly total without loading a separate calculator. For example, the shopping cart program I use for my book sales offers a summary table of all recent sales. While I can use a reports section of the site to get more information (e.g. monthly sales), I want a tool to quickly highlight the desired entries and give me the total of the individual sales. To do that I use a Regular Expression (RegEx) specifically for extracting those sales numbers. Continue reading

Finding UK Postal Codes (AutoHotkey RegEx Tips Part 2)

By Comparison, UK Postal Codes Offer a Greater Challenge Than US Zip Codes When Writing Regular Expressions (RegEx)

Note that a single space appears between “Birmingham” and the “B5 5QD” postal code. Without special recognition of the UK postal codes, the MultiPaste.ahk script won’t create a separate paste item.

In the previous blog (“Finding US Zip Codes (AutoHotkey RegEx Tips Part 1)“), I began this mini-tutorial series on AutoHotkey Regular Expressions (RegEx) with a technique for parsing US zip codes from street addresses. For the MultiPaste.ahk script to work best (“Parsing and Pasting One-Line Street Addresses (AutoHotkey Multi-Paste Trick)“), I needed any zip code to appear as a separate paste item in the MultiPaste MsgBox. The parsing problem occurs because most one-line address formats only use as a delimiter the space character (no comma or newline) between the state and zip code. The same holds true for UK postal codes.

Cover 200Last time, I pointed out how the string functions—InStr() and StrReplace()—require exact search characters while the Regular Expressions functions—RegExMatch() and RegExReplace()—can use a variety of wild cards to represent characters. In fact, the various different ways to express wild cards cause a degree of confusion. In this blog, I introduce the \w alphanumeric wild card and the question mark modifier (?) to create optional matches. Continue reading
