Difference between $CmdLine and _WinAPI_CommandLineToArgv

[mwhidden]

I'm not sure if this is the expected behavior, but the way $CmdLine handles escaped quotes is different than _WinAPI_CommandLineToArgv (which is recommended as an alternative for long argument lists) handles them.

Eg., When invoked like this:

AutoIt3.exe Test.au3 "A B\" C" A B C

$CmdLine gives 2 arguments after the length: [ ..., 'A B', 'C" A B C"]

_WinAPI_CommandLineToArgv gives 4 arguments after the script: [..., 'A B" C', 'A', 'B', 'C']

Is this as it should be?

Thanks,

Mike

#include <WinAPIShPath.au3>
#include <Array.au3>
_ArrayDisplay(_WinAPI_CommandLineToArgv($CmdLineRaw))
_ArrayDisplay($CmdLine)

That's a pretty unusual set of arguments.

I imagine, that AutoIt is being kind to you with $CmdLine, and not requiring the fourth quote, which is missing.

I expect otherwise, that $CmdLine and _WinAPI_CommandLineToArgv act the same, though I have never used the latter.

If one doesn't want spaces to be used as dividers between arguments, then quotes are required.

_WinAPI_CommandLineToArgv may be ignoring the second quote as a divider, because there is no fourth?

The fact, that the first 'C' seems to be in your second argument result for $CmdLine, would seem to indicate that AutoIt is a little confused and just abides by some predetermined policy.

If you wanted 'C"' to be a separate argument, you would have to enclose it as I just did, in single quotes.

Sorry, I think my explanation was not clear.

"A B" C" is a manufactured argument for illustration of parsing an escaped double quote embedded in an argument. A real-life example might be something more like

SendEmail.au3 "My boss said "Finish this script" today. Can you believe it? -MWhidden"

The single argument to the script would be a string with double quotes within it.
