EMERALD_CHAIN env var default not getting set

Maybe other ENV_VARS not getting set? I didn't check anything else.

Possible dup #35 ?

@whilei, enviroment variables doesn't set by default.
Emerald-cli delegates that to user. One can set then in startup config for their OS, or use per command like this:
EMERALD_CHAIN=mainnet emerald list

Or I didn't get your point right?

[whilei]

I have set EMERALD_CHAIN=mainnet in my dotfiles as an env var, and expected emerald to use the global var EMERALD_CHAIN=mainnet value if I don't override it with --chain on the command line.

# Here I don't use '--chain' because I expect it to be system default from env var.

~  ⟠ env | grep EMERALD

~  ⟠ cat ~/.dotfiles/etc/emerald.bash | grep CHAIN
export EMERALD_CHAIN=mainnet

Expected usage:

$ echo "export EMERALD_CHAIN=mainnet" >> ~/.dotfiles/etc/emerald.bash
$ source ~/.dotfiles/etc/emerald.bash
$ emerald list # <-- since no '--chain' flag given, use default env var value for 'EMERALD_CHAIN'
> 0xmymainnetaccounts
$ emerald list --chain=morden # <-- able to override default env chain setting
> 0xmytestnetaccounts

Does that make sense?

[r8d8]

Ah, I see.
Now it makes sense, thanks.
