Scripting: run() as function with get return code / errorlev

[Stefan]

I want to suggest to turn SC run into an function which can return the return code of the called app
(and even the whole stdout and stderr ?)


$uccess = run(%comspec% /c myApp para1);

If ($uccess == 0){msg "all went fine"}else{break;}





error level errorlevel return code returncode

+1 for error code return, also it would finally allow us to script synchronous scripts that call outside programs (i.e. it would wait for run to end instead of the script running ahead).
I would suggest that if it's desirable for run() to return its own error codes that the return value would be 'called program's return code'*1000;
Which would leave 0 as 0 and other codes you'll differentiate by length.

Edit: As for stdout/err I suppose that the function could receive two optional variables for that (if its possible for XYplorer to capture them).

This part is already possible:

run command, [directory], [wait=0], [show=1]

[Twisten]

Mmm, nope.
If you use 'wait=1' you're stuck until the program is finished, can't use XYplorer at all.
If you use 'wait=0' you run uncontrollably ahead and if you're in a loop that calls that command you might end up with multiple instances of a possibly resource demanding command.
If on the other hand run is a function and therefore the script doesn't move past it until it returns the value, your script can run without interrupting normal usage.

I've looked into this some weeks ago, and did not see a good solution. I might look at it again later.

I'd love to see that as well...

Atm, I'm using this approach (rudimentary but it works for me):

Once again find myself missing a nice clean way to capture command output in a script.

Had you seen this when you looked into it last?
