Gofmt is the usual tool for that
; echo 'mux.Handle("/add-referrer", handlers.LoggingHandler(os.Stderr,
auth.Trace(auth.IsAuthenticated(auth.IsReferrer(http.HandlerFunc(lh.AddReferrerHandler))))))'
> file
; cat file | gofmt
mux.Handle("/add-referrer", handlers.LoggingHandler(os.Stderr, auth.Trace(
auth.IsAuthenticated(auth.IsReferrer(http.HandlerFunc(lh.AddReferrerHandler
))))))
Usually piping to gofmt fixes syntax. But because gofmt doesn't split by
line length, it wont work. You can use a stream editor like sed to replace
'(' with '(\n' and then pipe to gofmt to fix that.
cat file | edit ",x,\\(,a,\n," | gofmt
mux.Handle(
"/add-referrer", handlers.LoggingHandler(
os.Stderr, auth.Trace(
auth.IsAuthenticated(
auth.IsReferrer(
http.HandlerFunc(
lh.AddReferrerHandler))))))
