This will slightly increase the memory used by a script (probably by less than 100 KB). This is because each function along with its parameters and contents must be stored in memory, even if it is never called. |
My scripts with a few function file includes (this one too) takes around 3k - for scripts and compiled exe's, should I expect something around 100k?!?  |

I meant the amount of RAM the script uses. In this respect, functions are just like any other part of the script: the more of them there are, the more memory is needed.
Simple functions probably consume only around 1 KB each (1000 bytes), but it depends on how many parameters it accepts, what the function does, etc. |

Thanks for keeping this updated and for adding "in", "between", etc. It's a great benefit to the community.
(If anyone just started following this topic, the first post on the first page contains the updated functions). |

Doesn't the semi-compilation process help at all? I thought that the memory addresses wouldn't even be created for functions/variables that aren't used.

Here are some that I use:
| Code: |
IsKeyReleased(a_szKeyName)
{
GetKeyState, state, %a_szKeyName%, P
If state = U
{
Return 1
}
Return 0
}
IsKeyPressed(a_szKeyName)
{
GetKeyState, state, %a_szKeyName%, P
If state = D
{
Return 1
}
Return 0
}
MouseEvent(a_xpos, a_ypos)
{
DllCall("mouse_event", uint,1, int,a_xpos, int,a_ypos, uint,0, int,0 )
}
IsProcessRunning(a_szName)
{
WinGet, szProcessName, ProcessName, A
if szProcessName = %a_szName%
{
return 1
}
return 0
}

Functions are all stored in memory because it was originally planned that they could be called dynamically, such as %MyFunc%(). Since that feature is still planned, it's probably best to keep all functions in memory (since there would be no way to determine for certain that they're never called). |

It would be really helpful if these functions could somehow reside in the stdlib and be called without including them.
The only way I can think to do this, however, would be to create a separate file for every command, since there can't really be a prefix. Is there another way this can be accomplished?

You may include the following in functions.ahk
| Code: | Functions_Init() { ; dummy function to initialise the library
} |
and you may call it once before you call any other function from the library, like:
| Code: | Functions_Init() ; call it once before any other function
MsgBox, % Random( 1,10 ) |

Great idea, thanks!
At least it's a shorter and more generic command to remember than the path of the include...

Thanks for the heads up Skan. Version 1.5 final uploaded with StdLib compliant initialization function.

I'm having some trouble passing the InputVar to StringReplace with this code since I re-downloaded.
Here is the function:
| Code: | StringReplace(ByRef InputVar, SearchText, ReplaceText = "", All = "") {
StringReplace, v, %InputVar%, %SearchText%, %ReplaceText%, %All%
Return, v
} |
But this puts the actual contents of the variable you pass to InputVar as the InputVar for StringReplace. Shouldn't it instead be like this?
| Code: | StringReplace(ByRef InputVar, SearchText, ReplaceText = "", All = "") {
StringReplace, v, InputVar, %SearchText%, %ReplaceText%, %All%
Return, v
} |

I actually snuck in an update a couple hours after my post which fixed the InputVar problem.

Oh, I just downloaded the latest version right before posting that; I'll re-download again.
I also noticed this:
| Code: | IniRead(v, Filename, Section, Key, Default = "") {
IniRead, v, %Filename%, %Section%, %Key%, %Default%
Return, v
} |
Can't the first parameter be removed since it doesn't matter what was in the variable before and it's returned by the function?
I think it should be:
| Code: | IniRead(Filename, Section, Key, Default = "") {
IniRead, v, %Filename%, %Section%, %Key%, %Default%
Return, v
} |
