In Glyphs, the built-in "Offset Curves" filter does this. In my testing you need to make sure you have nodes at extrema first. And there's no settings for terminations, "brushes," etc. as in FontLab, though x and y offset can be separately specified and the preview is live.
Yeah, Robofont has exactly what I was looking for. Just tried it with a demo version of RoboFont and was exactly like I wanted, but the stroke wasn't consistent all the time, see screen shot*. The outlined stroke was neither visible in spacing center.
Shit, I might have to buy Robofont just so I can finally work on the script fonts I never finish because working in Illustrator makes me even more hateful than usual.
Yeah! I was actually thinking of getting RoboFont just because of this feature, but if it’s not working easy I have to rethink it. I would really like to see the result in Spacing Center aswell, and above “problem” should work I think.
Put a node in the middle of each of those S-shaped segments so that the curve of each segment doesn't change directions, and I bet it will work. (I saw the same thing in Glyphs.)
But that totally ruins the whole idea of drawing these shapes for me, that extra node is something I could put as a last final stage, but after I put it there, the curve is not as flexible as it was without it.
I don’t think it’s needed according to the spec either, at least FontLab have never complained about these kind of shapes.
It may or may not be needed for the spec, but it is, I gather, needed for the math on which the stroke expansion depends.
In Fontlab if you use the cutting tool and draw from one off-curve point across the segment to the next off-curve point, your new node would be placed so that the serpentine curve pretty much retains its shape. Not sure if Glyphs or RoboFont have such a tool.
I'm a bit surprised that these programs don't have a function for placing that intermediate node automagically (or maybe they do and I just don't know about it).
Yo can do something similar using Inkscape "Path effects", and them export to EPS And if you mix Path effects and Spiro, you get all the flexibility you want http://www.youtube.com/watch?v=3OaLZuFZxdk
Double click the plugin and then restart Glyphs. You can enable it in the View menu. You have to use the Offset Outline Filter at least once for each master as it uses the same values.
Georg, haven't tried Glyphs yet, but how does Glyphs handle my example above? In a similar way as RoboFont? Meaning you have to put an extra node in the diagonal curve in order to make the stroke look even?
I’m guessing everybody would prefer that the stroke thickness was even all around, just like in Illustrator.
To improve the inflection points, I automatically insert a point. I will try to improve that. So if you later on want to expand the path, you need to add them manually. With the next version you can add inflection points by shift clicking with the draw tool (the same as to add extremes).
The Outliner extensions for RoboFonts will always preserve your drawing, so bad drawing will end up with bad/worse expanded paths. Expand the path and the point structure will be very logical, only adding joining segments (square, but, round) for outside corners and a straight line for inside corners.
I really believe that a designer should be in control of his outlines, in what ever state they are.
Illustrator does correct the outline path by adding points in the expanded path which is great but that is not a type design tool, neither is Inkscape. Nevertheless one can always use Illustrator or Inkscape to draw and copy/paste the paths into RoboFont.
Should a type design tool correct design decisions, by adding points?
What if one build an interpolation-design-space based on skeletons and the tool is adding pseudo random points?
One of the design/programming principles of RoboFont is that is doesn't contain any design related knowledge: like adding uncontrolled points.
Just to make things clear. The Offset Path filter works exactly like Frederik explained it. Only the preview filter adds the points to get a nicer result.

Yes I agree to that. But in this particular case I don’t agree Why? Well, if you want to draw a monoline font you really want the lines to be equal width plus you want the freedom to move the curves around freely to try out stuff. If you add that extra node, the freedom is gone.
Is there really such a problem if the tool would always create a monoline? Do you think people would complain when a tool is making their drawing easier? I don‘t think so. I think the opposite.
Should a type design tool correct design decisions, by adding points?
If I choose the outline stroke and set a width, that is also part of my design decision. When the stroke thickness change uncontrolled, it sort of ruins that, in my opinion
Perhaps, a check box to switch this off or on?
Lastly, you guys are doing a great job with your new tools. I feel I have to say that too so it doesn't sound as I only complain.

What does this mean? Only the preview has a precise stroke thickness? And when I expand I get a similar result like in RoboFont?
If the preview works, why can’t the expanded result also work? I don’t get it. Is it very hard technically?
@GeorgS Nothing happens in the console at the moment when I use the expand path filter nor when I try to view the expand paths preview. On startup of Glyphs I do see multiple console messages about "objc[6820]: Class __ARCLite__ is implemented in both /Applications/Glyphs.app/Contents/MacOS/../Frameworks/AGRegex.framework/Versions/A/AGRegex and ..." and then a bunch of locations within PlugIns within the Glyphs.app bundle. There is also one message "objc[6820]: Class GSSegmentPen is implemented in both /Applications/Glyphs.app/Contents/MacOS/../Frameworks/GSFontTools.framework/Versions/A/GSFontTools and /Applications/Glyphs.app/Contents/MacOS/../Frameworks/GlyphsCore.framework/Versions/A/GlyphsCore." Don't know if that's relevant or not.

I think I may have seen a demo of something similar for Glyphs, but I can't remember for sure.
In FontLab, you can use the Expand effect from Tools > Actions... > Effects.

Please post any issues you may find.

Can you have a look at the console? (put in Glyphs in the search field)

And what about the macro window? Is there something?
If that does not help, could you send me the .glyphs file?
This shows up in the macro window:
Did you run the Offset Curve filter on this font? You have to actually hit OK to get the effect.
