Fonts have a severe impact on build times

[timboldt]

I imagine this is more of a compiler issue (?), but I think it is worth noting here.

It is frustrating that including TinyFonts increases build times by 10x or more.

A partial workaround is to copy the desired font into your project, but it generally means renaming packages to make it work. (Maybe TinyGo 0.14 helps, now that it has module support.)

I also get frustrated when building https://github.com/tinygo-org/tinyfont/blob/master/examples/pybadge/main.go on my windows laptop.

It might be better to use tinyfontgen on dev branch to create your own fonts. You can use the bdf file as input to create a new font. https://github.com/tinygo-org/tinyfont/tree/dev/cmd/tinyfontgen

TinyGo caches things a lot better these days. Also compiler is faster overall than it was. Can we close this issue now in favor of new ones as needed?

I vote for closing inactive issues, we could take a look at this : https://docs.github.com/en/github-ae@latest/actions/managing-issues-and-pull-requests/closing-inactive-issues

And close them by being inactive for X months (instead of days as proposed in the link). In case this is still an issue (after almost three years) it could be reopened.
