[go-nuts] Re: resource cleanup in closure

after a bit of thought, its not ideal. it would work, but defeats part of the objective, which was for the optimisations to be transparent, having the defer, or callbacks, in the calling function breaks the isolation. i could insert callbacks in the base code which would just be redundant when

[go-nuts] Re: resource cleanup in closure

that might do it, the closures are actually being made by a New(type) call, and i was basically fixated by returning only the new instance (and maybe a error), but no reason not to return a callback destructor. maybe New isn't the right name anymore? the idea is to incrementally add a registry

Have the closure generator return the resource? https://play.golang.org/p/16pyo0gh8_s I'm not sure what you mean by using types instead, or even why you are trying to do this. Can you explain more? Matt On Sunday, January 21, 2018 at 3:17:20 PM UTC-6, simon place wrote: > > i wrote the code be

[go-nuts] resource cleanup in closure

i wrote the code below hoping that defer() would run when a funcs context was lost, not just when it ended.(which, without using closures, would always be the same thing, i think.) https://play.golang.org/p/HBrmBOkK1zJ as can be seen it doesn't, which begs the question; "how do you clean up ex

[go-nuts] Re: JSON and Embedded Types (Aliases)

Given the last playground post, I'd guess that the aliased type (i.e. 'int' here) is being used for visibility rather than the alias's new name. It's also a little weird to use embedded types that dont need to be (there's no method promotion here because 'int' has no methods), or seeing aliases

Hi Clinton, here’s a code review. Does BuildTool need to be an interface? Having methods on a pointer to nothing (type GoBuildTool struct{}) seems unnecessary to me. Also, why not have this at the level of package main? Same with graven/commands, graven/config, graven/domain, graven/util, since

[go-nuts] Re: Is there something similar to cmp in python?

There isn’t a standard library or built-in function that does both a comparison and less operation. For best performance you would write it for your type. For best generality you would write a library function that takes two interface{} values and converts them to the comparable types that work
