Convert Base
Convert Base from 2 - 36 via DllCall (thanks to Laszlo & Gogo)

Code: Select all

ConvertBase(InputBase, OutputBase, nptr)
{
    static u := A_IsUnicode ? "_wcstoui64" : "_strtoui64"
    static v := A_IsUnicode ? "_i64tow"    : "_i64toa"
    VarSetCapacity(s, 66, 0)
    value := DllCall("msvcrt.dll\" u, "Str", nptr, "UInt", 0, "UInt", InputBase, "CDECL Int64")
    DllCall("msvcrt.dll\" v, "Int64", value, "Str", s, "UInt", OutputBase, "CDECL")
    return s
}
example:

Code: Select all

MsgBox, % "Decimal:`t`t42`n"
        . "to Binary:`t`t"      ConvertBase(10, 2, 42)       "`n"
        . "to Octal:`t`t"       ConvertBase(10, 8, 42)       "`n"
        . "to Hexadecimal:`t"   ConvertBase(10, 16, 42)      "`n`n"
        . "Hexadecimal:`t2A`n"
        . "to Decimal:`t"       ConvertBase(16, 10, "2A")    "`n"
        . "to Octal:`t`t"       ConvertBase(16, 8, "2A")     "`n"
        . "to Binary:`t`t"      ConvertBase(16, 2, "2A")     "`n`n"
ExitApp
output:

Code: Select all

Decimal:       42
Binary:        101010
Octal:         52
Hexadecimal:   2a

I like this thread!

IniParser
Parse ini files and return an array of objects with "__SECTION" and relative keys as properties.

Code: Select all

IniParser(sFile) {
    arrSection := Object(), idx := 0
    Loop, READ, %sFile%
        If ( RegExMatch(A_LoopReadline, "S)^\s*\[(.*)\]\s*$", sSecMatch) )
            ++idx, arrSection[idx] := Object("__SECTION", sSecMatch1)
        Else If ( RegExMatch(A_LoopReadLine, "S)^\s*(\w+)\s*\=\s*(.*)\s*$", sKeyValMatch) )
            arrSection[idx].Insert(sKeyValMatch1, sKeyValMatch2)
    Return arrSection
}
Example

Code: Select all

obj := IniParser("test.ini")
For idx, item in obj
    For k, v in item
        If (k == "__SECTION")
            MsgBox, Ini Section: %v%
        Else
            MsgBox, % k . " - " . v 
Return

CryptBinToHex
Convert binary buffer to hex.
Thanks to nnnik: http://ahkscript.org/boards/viewtopic.p ... 1242#p8376.

Code: Select all

CryptBinToHex(ByRef sHex, ByRef cBuf) {
    szBuf := VarSetCapacity(cBuf)
    DllCall( "Crypt32.dll\CryptBinaryToString", Ptr,&cBuf, UInt,szBuf, UInt,4, Ptr,0, UIntP,szHex )
    VarSetCapacity(cHex, szHex*2, 0)
    DllCall( "Crypt32.dll\CryptBinaryToString", Ptr,&cBuf, UInt,szBuf, UInt,4, Ptr,&cHex, UIntP,szHex )
    sHex := RegExReplace(StrGet(&cHex, szHex, "UTF-16"), "S)\s")
}
Example

Code: Select all

FileRead, cBuf, *C C:\Windows\System32\drivers\etc\hosts
(FileExist(A_WinDir "\System32\Crypt32.dll")) ? CryptBinToHex(sHex, cBuf)
MsgBox, %sHex%

This function will only work if using Unicode. A small enhancement so that the function will be Unicode-aware should do the trick. Something like...

Code: Select all

DllCall(A_IsUnicode ? "msvcrt\_wcstoui64":"msvcrt\_strtoui64"
etc.
etc.
I hope this helps.

YMD(Date)

Converts a date from YYYYMMDDHH24MISS to YYYY-MM-DD

If Date is left blank, it converts the current date

ex... x=YMD()

if A_Now is 20140513092817 then the value of x as a string is 2014-05-13

YMD(DDate:="")
{
FormatTime, YMD, %DDate%, yyyy-MM-dd
return (YMD)
}

Doh!

I forgot to paste the actual code... Corrected with edit

Yes, it uses the format time function...

This just makes it easier to use in an expression...

ScaleToFit
Accepts the dimensions of a source rectangle and the dimensions of a destination rectangle.
Returns the dimensions of the scaled source rectangle that fits within the destination rectangle, at the largest possible size and while maintaining aspect ratio.
Also returns the x and y offsets which center the scaled source rectangle within the destination rectangle.

Code: Select all

ScaleToFit(width_max, height_max, width_actual, height_actual)
{
  width_ratio := width_actual / width_max
  height_ratio := height_actual / height_max
  if (width_ratio > height_ratio)
  {
    new_height := height_actual // width_ratio
    return {width:width_max, height:new_height, x:0, y:(height_max-new_height)//2}
  }
  else
  {
    new_width := width_actual // height_ratio
    return {width:new_width, height:height_max, x:(width_max-new_width)//2, y:0}
  }
}
Example usage

Code: Select all

ActualWidth := 200
ActualHeight := 300

Gui, Add, Picture, w%ActualWidth% h%ActualHeight% Border vpictureControl
Gui, +Resize
Gui, Show

GuiSize:
  dimensions := ScaleToFit(A_GuiWidth, A_GuiHeight, ActualWidth, ActualHeight)
  GuiControl, Move, pictureControl, % "w" dimensions.width " h" dimensions.height " x" dimensions.x " y" dimensions.y
return

MinorVersion := DllCall("Kernel32.dll\GetVersion") >> 8 & 0xff
BuildVersion := DllCall("Kernel32.dll\GetVersion") >> 16 & 0xffff

MsgBox, % MajorVersion "." MinorVersion "." BuildVersion

Disp()
This is a very short function I wrote for debugging purposes.
It just takes the content of a var and creates a displayable string for it.

Code: Select all

Disp(Obj)
{
    OutStr:=""
	If !IsObject(Obj)
	{
		If (Obj|0="")
		{
			If ((Strlen(obj)="")&&VarSetCapacity(Obj))
				return "BINARY" ;Todo *binary
			Else If (Strlen(obj)!="")
				return "" . obj . ""
		}
		return	Obj
	}
	Else If IsFunc(Obj)
		return "func(""" . Obj.name . """)"
	Else
		For Each in Obj
			If !(Each~="\d+")
				NonNumeric:=1
	If NonNumeric
		For Each,Val in Obj
			OutStr.=Each . ":" . Disp(Val) . ","
	Else
		For Each,Val in Obj
			OutStr.=Disp(Val) . ","
	StringTrimRight,outstr,outstr,1
	If NonNumeric
		outstr:="{" . OutStr . "}"
	Else
		outstr:="[" . OutStr . "]"
    return outstr
}
Example:

Code: Select all

Msgbox % Disp("ABC")
Msgbox % Disp({a:{b:{c:[func("Test")]}}})
Test(){
return 42
}
Output:
ABC
{a:{b:{c:[func("Test")]}}}

Here's something I use similar to nnnik's Disp():

Code: Select all

/* Function: repr
 * Return a string containing a printable representation of an object*.
 * Syntax:

 *                      output is surrounded in double quotes. Escape
 *                      sequences are represented as is.
 * Remarks:
 *     Object* can be an AHK object, a string or a number (integer OR float).
 *     Only generic AHK object(s) are supported. Other types such as COM, Func,
 *     File, RegExMatch, etc. objects are not supported.

What is the advantage of bitwise-and and bitwise-exclusiv-or over the tenary operator?

Code: Select all

min(x, y){
  Return x < y ? x : y
}
Same should apply for Maximum (x < y ? y : x).
