User Defined Functions

From AutoIt Wiki
Jump to navigation Jump to search

This page is a listing of libraries of user defined functions (UDF). These libraries have been written to allow easy integration into your own scripts and are a very valuable resource for any programmer.
This list is probably not complete (375 UDFs on 2023-01-21), but constantly supplemented. If you do not find a solution here, ask a new question on the forum.

The listed UDFs might have been written for older versions of AutoIt. So there is no guarantee that every UDF works smoothly with newer versions.
None of the UDFs has been tested by the maintainers of this list so you as a user need to make sure that they deliver the expected results.

When will an UDF be added to this list?
It should meet all/most of the general requirements for UDFs as described here.
In addition the following requirements should be met:

  • Documentation: So users can tell what the UDF is intended to do (mandatory)
  • Examples: So users can get an idea how to use the UDF. The more the better (mandatory)
  • Operating systems: Should support the latest Microsoft OS (mandatory) plus as many predecessors as possible (optional)
  • AutoIt: Should support the latest version of AutoIt (mandatory) plus as many predecessors as possible (optional)
  • Author: The author should still be active on the forum so he can reply to questions (optional)

What to do when one of your UDFs is missing?
Please send a PM to user water. Add a short description of the UDF and a link to the post in the Example Scripts forum.
