Weird exception; please help :S

[herenvardo]

I've just written the first lines of my game for nanoreno and, when I tried to make the first test-run, I got a exception showing on my notepad:

I'm sorry, but an exception occured while executing your Ren'Py
script.

ParseError: On line 16 of game/script.rpy: expected statement.

Ren'Py Version: Ren'Py 5.4.2

I don't want to paste here the script: it's still short, but takes more than a hundred lines, so I've attached it. If you look at it, you might notice that there is not too much content yet, and it's based (copy-pasting required lines) on the example game's script. The case of the line which gives the error IS copy-pasted from the example, and it works in it; so I'm completely lost in why this exception occurs.
Does somebody know how to solve this error?

Thanks in advance.

Okay, it definitely has something to do with you using tabs instead of spaces to indent things. I haven't totally tracked down what, though.

Okay, I tracked down the error, and it was a bug in Ren'Py that caused tab characters to be improperly handled.

Seeing as how this bug has been around for a while, without anyone noticing (since at least 4.3 or so), I think the right solution is to forbid the use of the tab character entirely, as it has lead to problems with many languages.

So the resolution to this is that this will generate a more appropriate error message in 5.4.3, giving the line number on which the tab character was encountered.

but... I use the tab key all the time in SCITE, and things seem to work fine...

Another problem with the script (easily fixed) is that the string variable interpolations are missing the closing 's' for each.

So, should be:

Code: Select all

DM "In your case (%(char_gend)s/%(char_class)s), the race is %(char_race)s"

Wow! Just made a 'Replace all' taking tabs for 4-space sequences and it worked... well, not at all, I've still some errors but these are more 'normal' (ie: some text colors become almost invisible). The thing is that the code now runs so I can find & fix the 'normal' errors.
Thanks for your help.

When I inscribed for NaNoRenO, I got this reply:

Welcome aboard. I hope we can see you during March as well- the forums are a great resource. Good luck!

Well, ShiraiJunichi has just proved right! I'd like to make the game without too much help, because it's an important personal challenge for me; but upon things like that of the tabs, I'd need a lot of imagination and luck to solve them by myself.

I don't know the editing software you use, but what I do know is that there are a lot of editors that insert an arbitrary amounts of spaces instead of tabs when you use the tab key. The editor I use, Notepad++, allows me to choose either to keep tabs or replace them by spaces, and also the amount of spaces to be used (tab size).

Another problem with the script (easily fixed) is that the string variable interpolations are missing the closing 's' for each.

So, should be:

Code: Select all

DM "In your case (%(char_gend)s/%(char_class)s), the race is %(char_race)s"

Yes, just noticed it. I tried the tab replacement and got the corresponding exception at this point. I was wandering on reference before I saw your reply in order to solve it

And sure I'll make more mistakes as I go on, 'cos this is my first work with Ren'Py. Fortunately, I've wide experience in programming and it is a great help when debuging.

[PyTom]

That's because SciTE (like most sane editors) subsitutes an appropriate number of spaces for each tab.

Good catch shaja.
