[go-nuts] Re: Debugging in Go seems to be a very difficult task to accomplish

Hi Gophers, I know this post is old and there's a lot online with different sometimes contrasting opinions on how to debug go programs. My question given the complexities involved in multi-threading in Go does the go team have any plans on creating a standard debugger. I'm currently looking at

Neat idea. Just some random thought: instead of adding all linters by hand maybe you could use what gometalinter already provide? https://github.com/alecthomas/gometalinter W dniu poniedziałek, 14 listopada 2016 14:27:26 UTC+1 użytkownik sri...@laddoo.net napisał: > > Hi, > > I'd like to announc

[go-nuts] Pointer use-case for Luar

I am working on [Luar](https://github.com/stevedonovan/luar), a reflection binding library for Lua. The library can convert pretty much anything between Go and Lua. Pointers do not make much sense in Lua, so the lib dereferences them before creating a new Lua value. Luar also features proxies: th

It looks like someone on Stack Overflow has answered your question[1]. You know your needs better than I do, but code generation seems like an unnecessarily complex way to unmarshal JSON code. I'd recommend taking a look at encoding/json[2] if you haven't already . 1. http://stackoverflow.com/a

Hi, This is a bit of a general post, not really a precise question. I've built a go application to test the validity of generated HTML markup (the sort you'd make with a static site generator, like Hugo or Jekyll) based loosely on an existing ruby gem html-proofer. It runs files through a serie

[go-nuts] Re: Sub-Benchmark strange results.

Confirmed bug on my part. When using the "..." suffix to pass a slice into a func with variadic args it passes through the the original slice, rather than constructing a new one. An obvious optimization, but caused my function to act differently in my tests vs. a real use case. The tests pass

[go-nuts] Rendering absolute URLs for a hypermedia API

I believe I have done enough research (and attempts) that this should be an easy answer: either it doesn't work that way or I've missed something simple! Fingers crossed and thanks in advance. My goal is to render absolute URLs for my API—I can't get route libraries (eg gorilla/mux) to do this
