Snippet Dump

jvanegmond · December 21, 2010

No offense at all. That's why we do these tests; To find the fastest and most correct method. I found a some small errors in the fastest method and that led me to rewrite it like this by doing simple things like putting the checks in the right order:

Func _ArrayModalSpin(ByRef $av_Array, $iClicks)
    If $iClicks = 0 Then Return
    Local $iElements = UBound($av_Array)
    If $iClicks >= $iElements Then $iClicks = Mod($iClicks, $iElements)
    If $iClicks < 0 Then
        $iClicks *= -1
        $iStart = $iElements -$iClicks
        $iResume = $iClicks
    Else
        $iStart = $iClicks
        $iResume = $iElements -$iClicks
    EndIf
    Local $av_Temp[$iElements]
    For $i = 0 To $iResume -1
        $av_Temp[$i] = $av_Array[$iStart +$i]
    Next
    For $i = $iResume To $iElements -1
        $av_Temp[$i] = $av_Array[$i -$iResume]
    Next
    $av_Array = $av_Temp
EndFunc

( Didn't test this version )

I had a look at when the large arrays are created and destroyed again and those are of course these lines:

Local $av_Temp[$iElements]
For $i = 0 To $iResume -1
    $av_Temp[$i] = $av_Array[$iStart +$i]
Next
For $i = $iResume To $iElements -1
    $av_Temp[$i] = $av_Array[$i -$iResume]
Next
$av_Array = $av_Temp

but you can rewrite this part like this:

$av_Temp = $av_Array
For $i = 0 To $iResume -1
    $av_Array[$i] = $av_Temp[$iStart +$i]
Next
For $i = $iResume To $iElements -1
    $av_Array[$i] = $av_Temp[$i -$iResume]
Next

so you essentially do the same thing but you save 1 operator: Defining a large empty array. This is still done in the new version but it happens on the inside of AutoIt. This brings us this new version:

Func _ArrayModalSpin(ByRef $av_Array, $iClicks)
    If $iClicks = 0 Then Return
    Local $iElements = UBound($av_Array)
    If $iClicks >= $iElements Then $iClicks = Mod($iClicks, $iElements)
    If $iClicks < 0 Then
        $iClicks *= -1
        $iStart = $iElements -$iClicks
        $iResume = $iClicks
    Else
        $iStart = $iClicks
        $iResume = $iElements -$iClicks
    EndIf
    $av_Temp = $av_Array
    For $i = 0 To $iResume -1
        $av_Array[$i] = $av_Temp[$iStart +$i]
    Next
    For $i = $iResume To $iElements -1
        $av_Array[$i] = $av_Temp[$i -$iResume]
    Next
EndFunc

Which gives us roughly a 20% speed increase. 8) Not much, but noticeable enough.

czardas · December 21, 2010

That's pretty cool, although I thought a problem might occur (I realize now that it still works). I believe the first check belongs after the Mod function. It may slow it down slightly otherwise. When $iClicks turns out to be either a multiple of $iElements or equal to zero, we want to quit the function at that point. It seems a bit silly to say spin the array zero clicks (or 360 degrees), so it's probably more useful to do it this way.

Func _ArrayModalSpin(ByRef $av_Array, $iClicks)
    Local $iElements = UBound($av_Array)
    $iClicks = Mod($iClicks, $iElements)
    If $iClicks = 0 Then Return
    If $iClicks > 0 Then
        $iStart = $iClicks
        $iResume = $iElements -$iClicks
    Else
        $iClicks *= -1
        $iStart = $iElements -$iClicks
        $iResume = $iClicks
    EndIf
    $av_Temp = $av_Array
    For $i = 0 To $iResume -1
        $av_Array[$i] = $av_Temp[$iStart +$i]
    Next
    For $i = $iResume To $iElements -1
        $av_Array[$i] = $av_Temp[$i -$iResume]
    Next
EndFunc

I never thought that copying an array would be faster than declaring an empty array of the same size, but if it's done internally, then I see why. 20% is a significant increase in speed.

Makes sense to reverse checks. I think this is complete.

czardas · December 22, 2010

I have removed the conditional statement at line 3 (post 24). There was still one problem. In this particular script, it seems to be 'universally' better to go for using the Mod function every time (without the checks). Otherwise an additional conditional statement would be required, however the extra code offers no clear advantage.

Running the same speed test (post 22) with the new version (post 24) gives 2960.22036320259. That's a big improvement from the original.

Also, I wanted to make a post why using only one array is not possible.

I wish I knew what you were doing. Sure reversing the final output gives a spin of -1 (by my original definition), but I don't understand why $aTemp is not a modified copy of $av_Array. Perhaps the format is slightly different. It seems like an interesting technique none the less.

$aTemp = [AA,DD,CC,BB]

MvGulik · December 28, 2010

1) "$aTemp":

Erm ... not sure what you main with $aTemp, although this might explain it.

local code:

Func testloop($aTemp, $iStep)
...
$aTemp[$i - $iFirst] = Chr(65 + $iConter1) & Chr(65 + $iConter1)
$iConter1 += 1
DebugOut('> $aTemp', $aTemp) ;### Debug DebugOut.

Seems I forgot to update the output to reflect the cleaned up posted version.

So $aTemp == $av_Array.

2) "not updated":

Well its a test case and I did not ByRef the $av_Array parameter in Func test_X($av_Array, Const $iStep) so I could keep feeding it the original $av_Array from SpinLoop(). That also made me not do anything else but updating the used array with debug information. :shifty:

3) "I wish I knew what you were doing."

Just playing around with a idea.

I did do a array processing function where I first took out one value/data to make a empty entry, so other data could be shuffled around whiteout having to temporary save one when swapping two data entries. (Think it was some randomize-array function.) Did the same thing here. At leased thats the base idea of the whole process. The rest is to fix the shortcomings and/or limitations of that process.

-a flip back to begin or array when the loop crosses the end of the array.

-b switch to next(unprocessed) entry in array when the loop loops back on the entry from which it started.)

-c continue until -b fails.

Note:

This will never be faster that your original code that uses 2 array's. Du_(?) to the additional code needed to keep the looping under controle.

So the only real benefit is less memory use (for the duration of the spinning) ... but with a array so big that it needs this ... I will question the user for using such a big array. :nuke:

Hope it make some sens.

@ MvGulik Ah Okay! In sound recording they call using an extra track 'bouncing' (or at least they used to). That's something similar to the empty array element you are using.

Now we have the modal string version.

Edit

To demonstrate the use of this function, I have replaced the original example with one which some of you will find more familiar. If you are uncertain what the example is about, you may wish to refer to the following article: http://en.wikipedia.org/wiki/Musical_mode#Modern.

jvanegmond · December 29, 2010

MvGulik, you're probably right. You can spin the array by 1 or -1 without using 2 arrays: You only need one extra variable (not array) to hold the object being shifted (in an a=b and b=a sense you also need c). If you repeat that process several times you are still only using one array, but spinning the array multiple times. Good thinking.

czardas · January 3, 2011

In addition to the spin effects, I have added two more modal functions. I have changed the definition of positive spin in _StringModalSpin (post 30) to comply with the other modal functions.

_ArrayModalSelect makes the job of looping round an array very simple. The beauty of this function is that you never have to worry about exceeding the number of array elements (error message) because the array is treated as having an infinite number of elements.

_StringModalSelect is similar to _StringModalSpin, however the return string can have any length.

At first I wasn't sure if I should have made the first post in help and support. But I think the discussion here has turned out to be a good example of finding ways to improve a script (which was already working). Whether anyone else will find these functions useful is unknown to me. I will definately make use of them myself. Please let me know your thoughts.

I started this thread for minor applications, or bits of code that may be of potential interest to anyone (perhaps someone just starting out will find something useful here). My more important projects seem to take for ever and occasionally I feel the need to write something really simple. So here's Log Dog - a very simple application which I made a while back. It's nothing more than an edit control which appends the time and date every time you press the enter key. The text is saved automatically in a file called logdog.log. You can use the enter key normally when you hold down the control key - don't know why though! :mellow:

The code also includes hotfixes for two (edit control) bugs which are known to affect some users of AutoIt. These issues could be related to each other, but the cause is a bit of a mystery. Thanks to the forum members who explained to me how to fix these issues using accelerators.

so here is the place to dump some snippets?

MvGulik · August 29, 2011

Well, AutoIt Snippets Database might also be a option. Not sure if its still working. But its still up. (But seems more suitable for final snippets.)

PS: Think sharing a snippets topic with multiple users is not such a good idea. As there is no general topic subject compared to

- Snippets + One user.

- Multiple users + Same code subject.

There are some interesting examples there, including _StringRotate - which is pretty much the same as

Funny coincidence!

I didn't want to say don't post stuff in here, but indeed you are right about what you say. Edited August 29, 2011 by czardas

Fuzzy Logic Date Extraction

Many people prefer to have a date written out in full, but that can mean a number of different formats. This code is intended to recognize a date in a variety of commonly used formats. The written date is converted to DD/MM/YYYY or DD/MM/YY, depending on input. While it may never be perfect, it's perhaps something that could be useful for some applications.

Requires revision

Three new functions to be added to Modal.au3, which incidentally I could no longer live without. These are simple and somewhat limited numeric base conversion functions:

_DecToNumBase

_NumBaseToDec

_NumBaseToNumBase

Negative numeric input values values are supported. The following list gives the decimal equivalent max value limitations on all supported numeric bases

    'Year,Make,Model,Description,Price' & @LF & _

        _ArrayDisplay($aCSV)
        MsgBox(0, "Converted back to CSV", _ArrayToCSV($aCSV))
    ElseIf @error = 1 Then
        MsgBox(0, "Error Code " & @error, "1st parameter - Invalid string")
    ElseIf @error = 2 Then
        MsgBox(0, "Error Code " & @error, "2nd parameter - Delimiter not a valid string")
    ElseIf @error = 3 Then
        MsgBox(0, "Error Code " & @error, "Failed to find suitable delimiter replacements")
    EndIf
EndFunc

You have the option to set the delimiter, so you can convert from CSV to TSV etc... The function should be able to handle all csv formats. Make sure your CSV, (or TSV) is correctly formatted.

NOTE

When converting from array to CSV, double quotes will not be added to any fields unless absolutely necessary. This means that double quotes enclosing an empty field in an original CSV will dissapear after conversion. I didn't see it as being necessary to enclose all fields, but it's easy enough to make such changes when required.
