Normalization of number prefixes and exponents was added in CL 160184 directly in cmd/gofmt. The same behavior change needs to be applied in the go/format package. This is done by moving the normalization code into go/printer, behind a new StdFormat mode, which is then re-used by both cmd/gofmt and go/format. Note that formatting of Go source code changes over time, so the exact byte output produced by go/printer may change between versions of Go when using StdFormat mode. What is guaranteed is that the new formatting is equivalent Go code. Clients looking to format Go code with standard formatting consistent with cmd/gofmt and go/format would need to start using this flag, but a better alternative is to use the go/format package instead. Benchstat numbers on go test go/printer -bench=BenchmarkPrint: name old time/op new time/op delta Print-8 4.56ms ± 1% 4.57ms ± 0% ~ (p=0.700 n=3+3) name old alloc/op new alloc/op delta Print-8 467kB ± 0% 467kB ± 0% ~ (p=1.000 n=3+3) name old allocs/op new allocs/op delta Print-8 17.2k ± 0% 17.2k ± 0% ~ (all equal) That benchmark data doesn't contain any numbers that need to be normalized. More work needs to be performed when formatting Go code with numbers, but it is unavoidable to produce standard formatting. Fixes #37476. For #37453.
