Build failure using TinyGo

[tdewolff]

See tdewolff/canvas#83 (comment)

It appears that this library cannot be built using TinyGo, is this something you'd like to support?

Hi @tdewolff. It would be great if TinyGo was supported by xdg (and implicitly by sysfont). However, I think it might be better to raise the issues on the TinyGo repository. It would certainly avoid a lot of workarounds on my part in order to make it work.

From what I can tell, two of the three issues you mentioned are already in work there:

ModeDir not declared by package os: there's already an issue for this (tinygo-org/tinyfs#4) and a PR (tinygo-org/tinygo#1903) which has been merged already.

Getuid not declared by package os: there's already an issue for this one as well (tinygo-org/tinygo#1886) and a PR (tinygo-org/tinygo#1892) which will hopefully be merged soon.

So there's only MkdirAll not declared by package os left. Maybe @gedw99 can open an issue there regarding this because it's not specific to the xdg library.

Are these issues on Go 1.16 only or does this reproduce with Go 1.15 as well?

Hey Adrian, thanks for the quick and in-depth response. I agree this would be better to take up with TinyGo!

tinygo now supports os.MkdirAll().

The next problem blocking "tinygo test" from working in sysfont seems to be unsupported uses of reflect in testify and go-spew, see
