stealFunc - steal only the required functions from a script

[Avi]

stealFunc v0.12

stealFunc is a function-oriented script (tool) to extract only the required functions from an ahk library .
It recursively processes the library file to only extract functions that are minimally needed.
From v0.1 , it has feature to scan a autohotkey script snippet and extract the foreign functions that are used in that script from another given script.

EXAMPLE USE -
The following function is based on the gdip library

Code: Select all

SetImagetoClipboard( pImage ){
	;Sets some Image file to Clipboard
	PToken := Gdip_Startup()
	pBitmap := Gdip_CreateBitmapFromFile(pImage)
	Gdip_SetBitmaptoClipboard(pBitmap)
	Gdip_DisposeImage( pBitmap )
	Gdip_Shutdown( PToken)
}

As you see it uses the following functions from Gdip lib-

Gdip_Startup
Gdip_CreateBitmapFromFile
Gdip_DisposeImage
Gdip_shutdown
gdip_setbitmaptoclipboard

These functions in the lib may be dependent on other functions in the lib which in turn may be dependent on more functions and so on...
Extracting only the needed functions manually can get tedious.
So to shorten the process, I made this script which is presented as function .

Code: Select all

return_script := stealFunc(function_list, function_file) 
;EXAMPLE
Clipboard := stealFunc("Gdip_Startup`nGdip_SetBitmaptoClipboard`nGdip_CreateBitmapFromFile`nGdip_DisposeImage`nGdip_Shutdown", "<path_to_gdip_lib>")

The script also has a gui added for user convenience and can be commented out anytime.


Below are screenshots of the GUI in action.

Tip - To check if the extracted file is OK and doesn't contain bugs, run it as a separate script. If everything is OK , you will not see an error.

This will come in handy, thank you wizard.

Yes it does come handy. I formerly used gdip.ahk worth 95 kb in Clipjump compiled exe but now I find that what I really needed was just 12 kb. !! Huge Save !!

v0.1

• Added feature to extract used functions from an ahk script (snippet) in addition to listing them manually. This should make the process a lot faster. See Documentation for more info

any other examples?

I have only tried it on Gdip and SM_Maths as I needed them. Just now tried it on another lib RichEdit for creating an example. I will soon put them in the documentation.

stealFunc v0.12
* added `r to the output
* little bug fix with block comments
* fixed bugs with nested functions

[Avi]

any other examples?

please see documentation. Now I provide 3 examples and thanks to you, I discovered 2 bugs while making them.

Script link works but Documentation just hangs.

Script link works but Documentation just hangs.

What do you mean ? Is the doc link invalid OR is an example is doc hanging the script ?
There was an error in example 1 (5 gdip functions) of the doc which I have fixed now.

I mean when I click the link Documentation I watch my cursor spin forever. I could get the script. Not the docs.

I don't know . The page is light and loads quickly.
Tried URLDownloadToFile ?
