compflag

Auto-completion for stdlib flag items

usage

you got two options here:

• Call compflag.Complete() somewhere before actual app logic, best point is right at the start:

    package main

    import (
        "os"
        "flag"

        "github.com/s0rg/compflag"
    )

    func main() {
        if compflag.Complete() {
            os.Exit(0)
        }

        flag.Parse()

        // other startup logic...
    }

• Define trigger flag for completion:

    package main

    import (
        "os"
        "flag"

        "github.com/s0rg/compflag"
    )

    func main() {
        compflag.Var("complete")

        flag.Parse()

        // other startup logic...
    }

Please note, that you need to exit app if any completion happened.

Build your app, put binary somewhere in your "PATH", then run:

    complete -C %your-binary-name% %your-binary-name%

if you prefer flag-triggered version:

    complete -C "%your-binary-name% -%your-flag% bash" %your-binary-name%

Now enter %your-binary-name%, and hit TAB twice )

shell compatability

This will work with any shell compatible with complete (bash and zsh are both good with it), for zsh you may need also use bashcompinit in addition to compinit.
