[go-nuts] Re: Runtime code generation?

You could let your application generate valid Go source, call the compiler to build a plugin, and load that plugin. I haven't tried that yet, but i think it should work. Downside is that you need to Go tools on the target machine for it to work. I don't know how many times you have to generate

Re: [go-nuts] Re: adding context.Context to new code

Our approach was to identify function calls that consume a Context (indicated by a call to context.TODO in the function body) and function calls that provide a Context (such as RPC and HTTP handlers). Then we use the guru callgraph tool to find all call paths from context providers to context consu

Hello Zachary Stdin and os.Args are quite different. If your wrote a go program named "kaplan", then when running the following command on a unix-like system (linux, or OSX) : cat bigphoto.jpg | kaplan sepia downscale > result.jpg you have os.Args[0]=="kaplan", os.Args[1]=="sepia", os.Args[

[go-nuts] Re: Creating shared-libraries which override existing system functions?

Excellent - thanks Donovan. Alas I've since discovered that since the program I want to preload is compiled using Go - it doesn't use libc and LD_PRELOAD won't work with it. But - a useful lesson either way. Cheers. -- You received this message because you are subscribed to the Google Groups "

[go-nuts] Re: Is it ok to separate Open and Close logic?

I would say don't do it unless there's something that you need to do and has no other way of doing so. Separating into functions require all calls to DoStuff() follows a call of CleanUp() somewhere down the path. it's difficult to maintainable and can cause subtle bugs (if not careful) when th

[go-nuts] strings and when to use them

in golang, strings are immutable. thus, if i want to modify a string in place, i'll need to cast or copy each element from the string to a similar but mutable data structure. this seems inefficient for simple command line programs that take input from stdin and access it through os.Args. can so

[go-nuts] Is it ok to separate Open and Close logic?

Most examples of opening and closing a file have both calls in the same function func DoFileStuff() { file, _ := os.Open("file") defer file.Close() // do stuff with file } This makes sure any open file is closed. But how common is it to separate that logic into functions? Should this be
