Use this thread as an Online Function Library. Everyone is allowed to post their functions for general use. Just like Jon's attempt to catalogue all most useful scripts at one place, this is mine for the functions. The difference is that you can yourself add your own functions here. You can link to the forum post relating to your function, or directly to the script file hosted anywhere. The next post is editable by anyone. Just login using the credentials given below and add your functions there.

It'd be nice for users if u categorize your functions.

Simple function, returns path of default browser so you can open links in new windows (with the system's default browser ofcourse).

I posted this somewhere else but for anybody who needs it...
This makes vars you might've got from FileRead/RegRead/IniRead that have escaped variables into real variables, see the example in the script.

i needed that sometime ago! by the way i think u should also link your cmd functions topic in this thread.

I put up a winfx function script.

Should I bump this topic everytime I post a new function

It probably depends on how often you add them. If it's only once a week, a bump is probably justified. If more often, perhaps you could update the post every time but only bump once a week.

Very nice collection - I'll try to add it to the Functions page of the AHK wiki over the weekend.

Returns the Factorial of a number-




Converts Hexadecimal to Decimal-

(positive and negative is not taken into account as I wrote it for colour conversion.)

I didn't notice that

I wondered why I couldn't find an existing function to do it

The function may be used if you are not sure if the SetFormat was set to hex before calling the function... Actually, no need for function if you never set it:
d := 0
d += "0x" . hexDigits

The topic is old, but I believe such useful list should go to the Wiki, easier to maintain than a list of messages.

Strictly speaking, the Factorial function is not correct, because it returns 0 for 0!, but the right value is 1. Here it is corrected:
As PhiLho said, if your current integer format is decimal (the default), you don't need a function to convert a hex number to decimal form. Just add 0 to the hex number and AHK converts it to decimal:

I'm curious as to why you define the local variables when there is no need to:
You can use A_FormatInteger and A_FormatFloat.

I didn't expect it to be that simple



I didn't notice that. Thanks for the amended version.

I was actually using that function for a Permutation script that I was writing yesterday (just to see if I could write one). After a couple hours of writing it, I found one you had written already that worked a hundred times faster


Thanks for your comments and corrections.
