Shout out to the Go team on a job well done. I took the time to re-run some benchmarks, here are the results (both 1.9.7 and 1.13.5 re-run on same hardware & OS). >From fixed iMac:tmp robertengels$ benchcmp bench_1_9_7.txt bench_1_13_15.txt benchmark

Re: [go-nuts] Re: modules exclude version and above

Ok, I think I've figured out what's going on. The commits tagged `v2.0.2` and `v2.0.3` in this repo have a module in subdirectory `v2` that declares its path to be ` github.com/nicksnyder/go-i18n/v2` . However, that module cannot match the requested path ` g

[go-nuts] Re: regexp syntax and named Unicode character classes

As Go's regular expressions are based on RE2, I always use the latter's documentation page to check what is and isn't allowed. Note though that: \C, which RE2 normally allows, isn't allowed in Go. Alan On Tuesday, January 7, 2020 at 6:21:58 PM UTC,

Re: [go-nuts] Panicking in public API ?

Many thanks everyone for the insight. Instead of accepting a raw query string and try to compile it, I will defer that part to the library user. So, I will simply accept a *sql.Stmt. That way, I won't have to handle the various failure modes within the library and leave the issue to the end user.

Ian, I did some more digging on the web and landed on this Go issue where you had a comment: https://github.com/golang/go/issues/18123#issuecomment-264590075. The original issue is related c-archive buildmode, but reading further on that thread, I am guessing that even for Go shared libraries

You are not checking return value of os.Remove in https://github.com/eikenb/pipeat/blob/master/pipeat.go#L51. That will fail on windows. You can take look at https://github.com/calebcase/tmpfile, which works on Windows. + Egon On Friday, 3 January 2020 19:50:20 UTC+2, drakk...@gmail.com wrote:

I'd suggest you expose both kind of APIs as in: * https://golang.org/pkg/regexp/#Compile * https://golang.org/pkg/regexp/#MustCompile Implementing the `Must` flavor is trivial, just call the standard func and panic() if you get an error. As a side effect you'll get a unique point where to panic()
