whitespace deals.. 0//

[Santeri Piippo]

So I was working on my little parts authoring tool (ldforge) again and ran into a little problemo: is there required to be a whitespace after the numeric code for comments? Is a line like "0// edge lines" valid or are they considered errorneous?

I would assume it's illegal but assuming is bad, so yeah. The specification doesn't seem to mention anything about this, maybe I am blind as usual?

It is an unknow line then.
The parameter of a line are separated by one or more whitespace.
In the case you mention "0//" this is the first parameter of the line, where a linetype 0 through 5 is expected. So it is an invalid line.
It's up to you as the author of the application what to do with that line

Code:

Basic parsing / file content

An LDraw file consists of one command per line. There is no line length restriction. Each command consists of optional leading whitespace followed by whitespace-delimited tokens. Some commands also have trailing arbitrary data which may itself include internal whitespace; such data is not tokenized, but treated as single unit according to the command.

Whitespace is defined as one or more spaces (#32), tabs (#9), or combination thereof.

I guess I am indeed still blind, then.

It's up to you as the author of the application what to do with that line

It'll be listed as an errorneous line in the code, such will have a little dialog for changing the contents of that line so you can fix the error without the need of a text editor.

Thanks.
