Deferred highlighting with vim.schedule causes issue about nvim-web-devicons HOT 4 CLOSED

fuuuu an user yesterday wanted to load hl groups when requested to load nvim faster. But then, telescope users reported that the get_highlight_name was causing errors because it's called asynchronously and suggested wrapping in vim.schedule.
I guess maybe we should just revert back to how it was before.

should be fixed, sorry for the inconvenience

Cool! Beyond the inconvenience, I do understand the point of making things snappier. If you're interested in reinstating the behavior, maybe we could work out an API that is async-aware? E.g. it could return none or a default HL group (Normal?) if the function is called before the devicon HL group is defined.
And btw what was the issue for non-vim.schedule for telescope?

from nvim-web-devicons.

telescope uses get_highlight_name in a lua callback, so when we moved the nvim_command call inside of it, it broke because vim functions need to be wrapped in a schedule call when used asynchronously.
This is not too important rn, async stuff should be treated with caution and maybe rethinking how to make it work would take more time. Breakage like this is not supposed to happen, maybe tests would be required at some point.
