Apologies in advance if this question falls a bit beyond the purview of this glyphs forum. GlyphsLib/FontMake now support Glyphs feature variations syntax! But if I _am_ using “ifdef” feature syntax, is there a way to build to VF _and_ static fonts? I’ve asked this question in the [glyphsLib GitHub repo](https://github.com/googlefonts/glyphsLib/issues/1175), so an answer/discussion there might be ideal. But, I wanted to get a bit of extra visibility on the question, and I know there are a few experts here. 🙂 I assume a couple of Glyphs-centric answers to my question are: 1. **Yes – use bracket layers to swap shapes.** This works pretty well if I only need one area of shape switching, but I can’t get it to work for multiple areas, as needed in a current width+weight family I’m working on. So, thus my excitement about using feature variations. 2. **Yes – export from the app, or build with the recently released [Glyphs CLI tool](https://forum.glyphsapp.com/t/command-line-tool-for-glyphs/36022).** Those are both decent answers, and I may move towards the CLI tool. Still, I like having the ability to use FontMake and open-source tools in builds, when possible. So, if I _am_ trying to build via FontMake, is there some approach that might work? I’ve just realized I miiight be able to get there with some combination of setting up exports/instances using custom parameters “Add Features” or “Remove Features” (for variable vs static exports) as well as “Rename Glyphs” and “Remove Glyphs” (for static swaps). I’ll try it out, and report back if I find a way! Aside from that, I’d still love to know if there might be some kind of more automatic approach. I’m imagining something like: - Some way to make FontMake or glyphsLib put the “ifdef” conditions into designspace rules, where multiple conditionsets can be used. I think this might be done for bracket layers, but my builds are failing if I have multiple conditions declared in bracket layers. - Custom parameters to control features and glyph swaps in exports.

It is nice that these are going to proper .fea syntax, as (I assume) we now have the ability to add variable conditions in any feature, which I don’t think Designspace rules allow. But, yeah, I’m a little unsure how to proceed, when I do want to export to both variable and static fonts from the same Glyphs source. > > I suppose one possible approach might be to build a variable font, then generate instances from that using the FontTools Instancer... > > But, is there some simpler way to just build static fonts from Glyphs, using FontMake, with swaps made appropriately?
