For those who are looking for a simple language to create scripts to make their lives easier at work or play, AutoHotKey (AHK) might just be the answer. It’s freely available, a small download, and comes with a user community that any software producer would be proud of.
What’s more, it can be used to build full Windows applications, with a GUI, just by specifying a few parameters on a single line.
What is AHK?
At its heart, AutoHotKey is an automation tool designed to interact with Microsoft Windows applications. Like AutoIt, for example, AHK can send clicks, messages, gestures, or any other interface manipulations to applications in a scripted fashion.
Beyond this, AHK has a rich programming (scripting) language which is designed to go a few steps beyond simple automation. With functions for data conversion, file manipulation, flow control, and dynamic creation of graphical user interfaces, it melds a simple syntax with advanced API manipulation.
The AHK Community
In fact, if there’s something that AHK cannot do, then the community of users is there to help. In many cases, they even provide complete solutions for other AHK users to download and use, including extensions for:
- Client & server TCP/IP programming;
- Handling binary files;
- Dynamic arrays and lists;
- Dynamic code execution (i.e. create and execute code within a script).
These are all delivered via the AutoHotKey Wiki which is a community driven information repository for all things AHK. Besides the scripts, there are tutorials and help files for the AHK system.
AutoHotKey Hot Key Macros
The name stems from the ability to apply any of the scripts to load, and stay dormant, until a hot key combination is pressed. At this point, the script is executed. This enables the programmer to do things as simple as expanding abbreviations as they are typed, through to intercepting all manner of interactions with the interface to emulate joysticks, mice, keyboards and so on.
Developing Windows Applications with AutoHotKey
The strength of this software, though, has to be in the ability to create a full GUI application, and then compile and bundle it into an executable file that can be run on any Windows PC. All the overhead that Win32 API programming is typically associated is dealt with by AHK itself.
This includes the ability to call DLL functions (such as WinSock, or security libraries), which makes API programming, and extending AHK’s already rich language, a snap. Essentially, it is an entire programming suite in a box, without the need for a complex compiler environment.
These features make AHK, if not unique, then certainly amongst the most useful tools that a Windows user can have at their fingertips; and for programmers it is a real boon for those involved with testing, automation, or rapid prototyping of new products.
