How to use -printerror and -formaterror

I am have trouble the new Hollywood 9 console arguments -printerror (and -formaterror).
I created this faulty script (see missing "n" of the word "Function"):
Code: Select all
Local Functio p_myDebugPrint(p1)
DebugPrint(p1)
EndFunction
On Windows in the standard command prompt I run the script like this and get the error message in a popup:
Now, when I run the script with the -printerror parameter, no popup dialog is shown (which is correct) but there is also no output in the command prompt:
How is that intend to work?
Additionally, do you have an example on how to use -formaterror? I don't get the documentation, sorry.
This does not work ("syntax error") also not when enclosing the last parameter in ""):
Code: Select all
Hollywood test.hws -printerror -formaterror @_hwerror<line>:<file>*<message>
Thanks!

This is because Windows distinguishes between console and Windows programs. Windows programs such as Hollywood.exe don't have access to the current console's stdout etc. handles. That's why Hollywood comes with a separate version just for the console. It's called Hollywood_Console.exe and it's in the same directory as the other Hollywood.exe, which is the same program but using the Windows instead of the console subsystem. So you have to use Hollywood_Console.exe if you want to capture stdout output.

You mustn't pass any parameters to -formaterror. It's just a boolean argument that doesn't accept parameters. The error format used by -formaterror is fixed and will always be like this:

Perfect, thanks a lot for the clarification! I was aware of that file but wasn't sure when to use it. Now it seems obvious to me ... It seems those infos you posted are not in the documentation, are they? Maybe you could add that.
Another thing regarding this, which should probably be posted in the "Wishlist" section: Currently, if there are more than one sytnax errors in the file you only get the first error. If you correct that and run/compile you get the next error. It would be nice to get the whole list of errors (one on each line) at once. Is that possible?
Thanks!

Well, that's rather special interest. People using the IDE normally don't have to mess with those executables so I don't want to unnecessarily confuse them.

It's possible but certainly won't come. This would mean that the parser would have to go on parsing even when a syntax error has occurred. Other programming languages do that and I've never liked that because all the other errors that come after the initial one can obviously be very confusing because as soon as there is a syntax error all sorts of misinterpretations can happen so all errors after the initial one can be very random.
