Hi All, <first post>

I am having some problems trying to create a scheme for Ingres and/or OpenRoad.

I am using the portable version of PN (nice).

I see in the forum some talk of .schemedef files – i do not see any of these in the portable version.

I have tried copying existing .scheme files and associated them through the Tools > Options > Files > Add button, but no luck.

Any pointers would be greatly appreciated.

It took me some time to find where things are explained, too. It seems that all of the .scheme files refer to lexers that are built-in to the Scintilla SciLexer.dll file. Unless the language you’re trying to add is 100% compatible to one of those built-in lexers, yeah, you need to make a .schemedef file. Here’s an example file for prolog. I think I got it from somewhere on here.

<?xml version="1.0" ?>

<!-- This is a very improvised, kluged schemedef for Prolog, written without

documentation of Programmers Notepad scheme definition syntax.

Main limitations:

No folding of comments.

Quoted atoms with a quote doubled ('don''t panic') are not treated correctly.

Escaped quoted atoms ('don't panic') are OK and are preferred.

Thanks Roody – that has helped me get something started.
