rhysd / go-github-selfupdate

When building a release with multiple artifacts (e.g. with goreleaser),
I found out that the self update cannot figure out which is the correct one.
As a matter of facts, this line tells that the first asset found with matching release, arch etc is
selected:

go-github-selfupdate/selfupdate/detect.go

Line 52 in 80762b8

if strings.HasSuffix(name, s) {

I am proposing a fix here along the following lines:

add a type Option func(*settings) to capture some specific settings
add a type settings{filters: []*regexp.Regexp} to capture specifically a filter on assets (might be extended later on)
add an option functor like func AssetFilter(filter string) Option` to add some filtering regexp (note: invalid regexp panics...)
supplement the line above by a check on optional filters and select the first asset which matches any of the provided filters. If no filter is provided, keep the existing behavior
most public API calls (not all of them, though) are amended with a opt ...Option optional parameter, so we may pass the filter down to findAssetFromRelease

Would that approach look acceptable?

Cannot isolate asset from releases with multiple artifacts
