line break in string?

EvanReese

how do I add a line break to a string in FS? Is there a place I can go to see all of the formatting options available?

reportFeatureInfo and reportFeatureWarning messages don't handle line breaks and other methods of formatting like \b (for bold). On the other hand, it is possible to use template strings to display units properly, but that doesn't really help a whole lot with your use case.

ah! I had a backslash not forward. Thanks!

EvanReese

hmm I thought that would solve it, but I'm still getting something else wrong. Here's what I'm trying to do, but it's still all one line:

reportFeatureInfo(context, id, toString(roundToPrecision(wrapCount, 3) ~ " wraps. \n" ~ toString(roundToPrecision(wrappedDiameter/inch, 3) ~ " in wrapped diameter.")));

Didn't know about template strings. Thanks, Alex! I feel as though I've seen features with line breaks in the reportFeatureInfo(), but it was a while ago and maybe that's changed. I think it's nice to have the option to format those.

I'm trying to implement the templateString, but it doesn't seem to respect the document units. I'm still getting meters. This is the code and result. Any ideas?

        var wrappedDiaString = templateString({'template' : '#dia#  wrapped diameter.', 'dia' : wrappedDiameter});

        // creating the messages
        reportFeatureInfo(context, id, toString(roundToPrecision(wrapCount, 3) ~ " wraps. " ~ toString(wrappedDiaString)));

Sorry, TemplateString is for tables only.  And in any case, as soon as you call toString on it, it becomes a plain old string.

Alex_Kempen

Yeah, @ilya_baran is right. I guess I saw someone using template strings to format output once and assumed it worked without personally trying it.

EvanReese

Got it. So is the best way to display valueWithUnits in a human way to just divide the value by whatever units I want to display and round it?

ilya_baran

@Evan_Reese yes

EvanReese

Thanks, Ilya

I suppose if you really want to have error info to sift through you could throw out some println() or debug statements to neatly display the information you want. However since this display in the FeatureScript notices panel it's really more useful for the dev as opposed to the user, which it looks like is your target with this error message.

Yep. this is meant to be user-facing. We're working on a fabric that wraps around a spindle and I'm calculating how many rotations a given length of fabric takes to roll up and the diameter of the final spooled fabric. I'm using FS to do some calculations since it sounded easier to me than trying to set up a spreadsheet for it, and it's nice to have it right in Onshape where we're working. I'm not actually using the feature for modeling or setting variables.
