PureBasic Forums - English

Invalid variable names with umlauts are truncated after the umlaut in the debugger's error description.

Copy the following code into the IDE and press F5

The message will be:
Line 3: Variables must be declared for ‘EnableExplicit’; H.

If you wrote Hutte instead of Hütte, the message would be correct:
Line 3: Variables must be declared for ‘EnableExplicit’; Hutte.

I find it as no bug, but a rule in the programming that no special characters may be used (ÄÖÜ, etc)
This is not only the case with PureBasic

That's not what he reported as a bug.
The reported bug is the faulty error message.

It might be a bit confusing, but the error is correct as 'ü' is not a valid char for a variable, so the parser stop at it. It then check if the variable exists ('H') and then raise the error. If EnableExplicit is not set, then a syntax error is raised because it tries to go further with the H variable and find an invalid character.

I can understand the explanation on a technical level...

If the parser stops nicely at the “ü” and the supposed variable ‘Hütte’ is only marked internally as “H,” then the error output has virtually no choice but to output “H.”

...but it may be confusing for inexperienced users if only the first letter is displayed.

And if you declare the variable correctly or omit EnableExplicit, you get error messages that don't point to the actual problem but mislead the user:
Will result in: Line 1: “)” expected!

Will result in: Line 1: Syntax-Error

And here too (even if it sounds a bit nitpicky): What actually sounds like a correct error description could unsettle an inexperienced user if hi expect that “Syntax error” means hi have written a command incorrectly. In my opinion, if a variable name is used incorrectly, it should be pointed out that the name of the variable does not comply with the conventions.

E.g.: “The variable name ‘Hütte’ contains invalid characters.”

But as I said, I can understand the explanation on a technical level, and I don't know how complicated it would be to extract the variable name completely despite the use of incorrect letters or characters for the error message.

I think that would also be good and possibly easier to implement:
"Error: Invalid character at: line 1, pos 11"
or
"Error: Invalid token at: line 1, pos 10"
