schemedef does not handle dashed for comments

[ravecoyote]

Trying desperately to create a schemedef for AlanIF - an adventure language like Inform6.

For this I have to declare a double dash -- as the beginning of a line comment. This seems to be completely ignored by PN. PN tries to parse the comment lines without recognizing them as comments.

Please help. This bug is driving me nuts.

Please attach the schemedef you're trying to use, I'll see if I can work out what's happening when I get some time.

Hi Simon,

attached you find the schemedef file. I'd be really happy if you could help.

Thanks Kristo

Hmm, sadly attachments don't work for the github tracker. Please either put it in the text, or (better) follow the instructions here to create a gist and send me the link: https://github.com/ned14/BEurtle/issues/1

Here's the download link for the relevant schemedef and a source sample file:

Ok, I think in this case it's because numbers have a higher priority than comments (which is perhaps a mistake). -- matches both your comment configuration, and also your number configuration (starts with -, contains -).

I think if you remove the ability to start a number with -, then it should work?

e.g.

<numbers start="[0-9]" content="[0-9.]" />

Let me know!

Hi Simon,

I've already tried that countless times. But that doesn't seem to make any difference at all.

Cheers

Ah, apologies, so it's not just numbers that take preference but also keywords. If unspecified keywords have a start set that includes '-' as well. So the combination of these two works for me:

<keywords start="[a-zA-Z0-9_]" />
<numbers start="[0-9]" content="[0-9.]" />

Aaaaah... now that did it! I'm really glad you could help me here.

One more question though: Please take a quick look at this piece of Alan3 code:

Exit south To bar Does If cloak In hero Then Locate hero At dark_bar. Else Locate hero At bar. End If. End Exit.

Can I somehow make PN recognize the integrity of such control structures. Something like

Begin_keywords: If then in Middle_keywords: else End_keywords:"end if"

Cheers

There's no way to do this with a custom schemedef, you'd need to write a Scintilla lexer in C++ and it would be non-trivial - most lexers avoid needing to keep much state between lines.
