Re: [go-nuts] Re: [Blog] Context should go away for Go 2

For the general interest: I wrote up my thoughts on this in a lengthy blog post: Why context.Value matters and how to improve it In particular, I sketch a design how context.Value could be made a language-lev

[go-nuts] Re: Go based JSON Escape/Unescape

Oh, yeah, true. Thx a lot. BTW, I *found* the rule on what are to be escaped so that I can embed any arbitrary content as a JSON string: *The following characters are reserved in JSON and must be properly escaped to be used in strings:* - Backspace is replaced with \b. - Form feed is re

[go-nuts] Go based JSON Escape/Unescape

Has anyone done Go based JSON Escape/Unescape yet? I want to pass any arbitrary content as a JSON string: { "content": "my escaped strings {\n \"employees\": {\n \"employee\": [\n {\n \"id\": \"1\",..." } In order to pass a JSO

[go-nuts] Any way to access the raw IANA Timezone data?

Hello, I'm looking to generate accurate VTIMEZONE objects according to RFC5545, and I need a reasonable way to access the raw information regarding DST shifts. I've read through the time package and I see there's a function called `LoadLocation` in src/time/zoneinfo.go, but I don't see any means

Dave, Slice lengths are a Go rule. off_t and st_size are POSIX rules. Peter On Sunday, August 13, 2017 at 10:07:08 PM UTC-4, Dave Cheney wrote: > > I can't find the reference at the moment, but a while back when this issue > came up regarding slice len, Robert Griesmer opined that signed inte

[go-nuts] Re: A small question on os.FileInfo

I can't find the reference at the moment, but a while back when this issue came up regarding slice len, Robert Griesmer opined that signed integers are preferred when counting things because unsigned counts don't go negative, they go insanely positive on wrap around. The rule of thumb I draw fr

[go-nuts] Re: A small question on os.FileInfo

Timothy, struct stat { /* ... */ off_t st_size;/* total size, in bytes */ /* ... */ }; off_t is a signed integer. File offsets can be negative. Peter On Sunday, August 13, 2017 at 8:27:21 PM UTC-4, Timothy Raymond wrote: > > I was working with filepath.Walk(), and I noticed

[go-nuts] A small question on os.FileInfo

I was working with filepath.Walk(), and I noticed something peculiar about the os.FileInfo interface that the filepath.WalkFunc receives. According to the definition here: https://golang.org/pkg/os/#FileInfo, the Size() method returns an int64. Shouldn't this be a uint64? Is there a sane instanc

Re: [go-nuts] Built-in log Package

I'd consider it quite sensible to log an error *and* handle it (e.g. by retrying). In that case, I wouldn't want it to appear with error-severity in my log - it might be an error string, but it's not an error condition. Only after bailing on handling an error should it stand out in an error log. So

[go-nuts] Built-in log Package

Many packages use the built-in log package. It could log data with help from it's type. If we could set the output of the logger to something other than *io.Writer*, like: type Output interface { Printf(format string, vset ...interface{}) Flags() (flag int) Prefix() (prefix string)

Re: [go-nuts] Suggestions for go 2

FWIW I'm strongly -1 on having date-related data in binaries. I think that having a deterministic relationship between source and binary for a given compiler version is an extremely useful property. On 12 Aug 2017 22:48, "Ian Lance Taylor" wrote: On Sat, Aug 12, 2017 at 1:52 PM, Robert Solomon

Hi there, I'm writing a Web based media viewer and I've hit a snag about how to mark up different media. My current code here: https://github.com/kaihendry/lk/blob/5de96f9fe012e9894deef7b9924f96dd8d9c806c/main.go#L181 is certainly wrong. I am puzzled how to use a template here in light of http
