Solve nested components

So now we have only one "fail" from fontbakery: "found-nested-components"

arrowtype/recursive#412

Do you know any tips to fix this?

From From https://github.com/googlefonts/fontbakery/blame/8cf2698f36d8e6562444c0f8b09104bc75e709c5/Lib/fontbakery/profiles/glyf.py it looks like @simoncozens recently authored this check.

Simon, Do you know any tips to fix this?

I guess if this is resolved the tips should be added to the fontbakery check metadata :)

Looks like ufo2ft has a mechanism to flatten components on export (by adding a filter to the UFO). Maybe I’ll use GlyphsLib then ufo2ft rather than a direct fontMake export. Should solve it.

[simoncozens]

For now that’s the best answer. I’ll work on getting a fontmake flag to do it.

@aaronbell @simoncozens Could fontmake solve this? or do you have workaround proposal for now?

[simoncozens]

I have pull requests against fontmake and ufo2ft. If/when they are merged, it will be easy to solve. Until then, convert to UFO and add the lib key that Aaron mentions above.

@minjooham I will take care of it in a build script to convert to UFO and then build the font. No need to change the source format in the repro.

Great! Thanks a lot @aaronbell

[davelab6]

What is the current status of this?

[aaronbell]

@davelab6 i will be able to resolve it in the build script. :)

The branch / PR that I created flattens components and resolves this issue :)
