How to delete empty key in the file?

[ahmetpi]

Hi,

I have an ini file like the one below

How can I delete keys that have no value in this file? (08:30 and 08:50 in the example)

Thanks

example ini

[MONDAY]
08:00=example1
08:20=example2
08:30=
08:40=example3
08:50=example4
08:50=

• Read in the section with IniReadSection.
• Modify the resulting array to remove the desired entries.
• Use IniWriteSection to output the modified array, thus overwriting the prior section

@ahmetpi, btw, your example has duplicate keys:

08:50=example4
08:50=

This should never happen if using only the INI functions.  I assume it’s just because of a hastily thrown together example, but thought I would point it out in case it’s not.

Func Example()
    ; Create a constant variable in Local scope of the filepath that will be read/written to.
    Local Const $sFilePath = "Test.ini"

    ; Create an INI section structure as an array. The zeroth element is how many items are in the array, in this case 3.
    Local $aSection[4][2] = [[3, ""], ["Test", "AutoIt"], ["Test", @AutoItVersion], ["Test", @OSVersion]]

    ; Write the array to the section labelled 'General'.
    IniWriteSection($sFilePath, "General", $aSection)

EndFunc   ;==>Example

To answer the OP's question, this could work

$txt = StringRegExpReplace(FileRead("example.ini"), '(?m)^[^=]+=\h*$\R?', "")
Msgbox(0,"", $txt)

I stand corrected, its absolutely possible. Thanks.

I wrote it twice by mistake
sorry

Duplicate entries are possible, but not recommended and can lead to unpredictable results.

There are programs, that will take for duplicate keys the first value when reading the ini, others will take the last one.

And Autoit is behaving differnt for "duplicates already exist" and "no duplicates so far". Basically: The results are hardly predictable, and duplicates for most purposes should be avoided IMHO.

 

Example()

Func Example()
    ; Create a constant variable in Local scope of the filepath that will be read/written to.
    Local Const $sFilePath = "Test.ini"

    ; Create an INI section structure as an array. The zeroth element is how many items are in the array, in this case 3.
    Local $aSection[4][2] = [[3, ""], ["Test", "AutoIt"], ["Test", @AutoItVersion], ["Test", @OSVersion]]

    ; Write the array to the section labelled 'General'.
    IniWriteSection($sFilePath, "General", $aSection)
    ShellExecute($sFilePath)
    MsgBox(0, '', "waiting")

    for $i = 1 to $aSection[0][0]
        IniWrite($sFilePath,"General",$aSection[$i][0],$aSection[$i][1])
    Next
    ShellExecute($sFilePath)
    MsgBox(0, '', "Written ""over"" results in just the first occurence is written to three times")

    IniDelete($sFilePath,"General")
    for $i = 1 to $aSection[0][0]
        IniWrite($sFilePath,"General",$aSection[$i][0],$aSection[$i][1])
    Next
    ShellExecute($sFilePath)

EndFunc   ;==>Example

Yes, I agree.  I would have said as much earlier, but I was so mortified by my inaccurate statement that I thought it best just to admit I was wrong, instead of seeming to say “Yes, but...”
