Is unwrapping the right behaviour here? In case we couldn't determine $HOME previously, it looks like we just didn't parse this file?

This does an awful lot of allocation, given that we only use one item from it.

I'd probably just use a boolean here, since the actual count doesn't matter.

It looks like the test failure is hitting against the TODO in parley/parley/src/layout/cluster.rs Line 477 in 13fd37b |

I believe this PR isn't the cause of the test failure, but simply uncovered an issue where the test isn't explicitly using a known font. I'll likely have time to look at it, but perhaps not today. |
