Title: script wizard and assert()
Post by: LETARTARE on June 11, 2013, 10:43:50 am
hello,
in the Squirrel 3.0 reference manuel found :

Quote
assert(exp)
throws an exception if exp is null

is that this function is available in the wizard scripts ?

if not, how to raise an exception in a wizard script?

thank you.

As far as I know we're still using squirrel 2.x, so you have to check its manual.

OK. Have you tried it?
What do you expect to happen?
Who is going to catch it?

Why?
But I'm sure it won't happen, probably you'll get an error in the log or it will be silently ignored.

I think I misunderstood

in fact, this is what happened during the test
Code
local board = null;
assert(board)

This exception should be recovered by "Code::Blocks" to notify the user ?
This is not the case.

I don't understand sorry. Please explain better or provide a sample script.

I tried the code in "Scripting console", there will pop an error message box, and no crash of C::B.

Welcome to the script console!

If I add the code in a project wizard script, then I see a message box said: script error has occurred, please press yes to see the exact errors.

Then I click Yes, there will be a dialog to show the detailed error messages. Still no crash of C::B.

@ollydbg
thank you very much for taking the time to check these two lines of code.

So I try on the other machine with the same configuration, and I confirm your results: we get the warning messages.

I incriminates my first PC, I'll check.

Thank you again for the constructive responses
