goenv install flags (--list)

[sighmin]

Thanks for getting this started dude.

It would be great to have a --list flag for the goenv install command o see what versions are available.

@sighmin Cool idea. 😄

@wfarr Here are a couple potential implementations:

1. Open Go Downloads page in a browser
   • open https://code.google.com/p/go/downloads/list
   • Super simple but cumbersome
2. Add and maintain a list of available binaries
   • goenv/share/goenv just like ruby-build
   • goenv install --list powered by list_definitions
   • Better user experience

Thoughts? Thanks!

@wfarr I thought of a third option; it doesn't require extra files.

3. Add and maintain an array of available binaries

• In libexec/goenv-install, set array using platform, arch, and extra
• No need for full definition files since we aren't compiling

Potential array implementation:

bash-3.2$ echo $platform
darwin
bash-3.2$ echo $arch
amd64
bash-3.2$ echo $extra
-osx10.8
bash-3.2$ VERSIONS["darwin_amd64_osx108"]="1.2.1 1.2"
bash-3.2$ VERSIONS["darwin_amd64_osx106"]="1.2.1 1.2"
bash-3.2$ key="${platform}_${arch}_$(echo ${extra} | tr -d '[:punct:]')"
bash-3.2$ echo $key
darwin_amd64_osx108
bash-3.2$ echo ${VERSIONS[$key]}
1.2.1 1.2
bash-3.2$ for version in `echo ${VERSIONS[$key]}`
> do
> echo $version
> done
1.2.1
1.2

Thanks for considering!

How's this? #6

I went with the third version. Sorry if it's not leet I'm not a bash expert.
