# Formatting Errors
#     Since gofmt returns zero even if there are files to be formatted, we use:
#
#       ! gofmt -d ${GOPATH}/path/ 2>&1 | read
#
#     to return 1 if there are files to be formatted, and 0 if not.

# How can I use Bash syntax in Makefile targets?
#     Because `read` is a bash command.

# How to ignore bindata.go
#     Due to irrational insistence of some Go developers, gofmt, like many
#     other tools of Go ecosystem, does not have flags for common scenarios
#     such as ignoring certain files by pattern etc. Thus we use `go list`
#     and grep together to achieve the desired result.
#
#     The original query is this:
#         gofmt -l $(go list -f $'{{range .GoFiles}}{{$.Dir}}/{{.}}\n{{end}}' ./... | grep -v bindata.go)
#
#     The original query is then escaped for Makefile (by repeating dollar signs $ -> $$).

check-formatting:
	! gofmt -l $$(go list -f $$'{{range .GoFiles}}{{$$.Dir}}/{{.}}\n{{end}}' ./... | grep -v bindata.go) 2>&1 | tee /dev/fd/2 | read
	! gofmt -l $$(go list -f $$'{{range .GoFiles}}{{$$.Dir}}/{{.}}\n{{end}}' ./... | grep -v bindata.go) 2>&1 | tee /dev/fd/2 | read
