flox displays active environment // flox envs

[ghudgins]

Motivation

When my terminal preferences are overriding flox's prompt (#637)
I need flox to display the active environment(s) in its commands
So I can know where I am

Acceptance Criteria

• Print active environment info in flox
• flox : when at least one env is present, the help text to use flox init is replaced with a list of active envs (or “no active envs”)
  Design details in https://www.notion.so/floxdev/View-environments-CLI-design-8f68c6465e944cba8f3ab474b1785ca4?pvs=4

Also covered with flox envs --active, implemented in #934

+1 from research. person had #678 issue and wanted flox status

[ghudgins]

questions flox status could help answer (from @rossturk )

• am I in an environment or not?
• am I in more than one environment? in what order are they layered?
• what's my sync status? do I need to run a pull?
• what's my freshness status? would things change if I ran an upgrade?
• do I have known security issues (dun dun DUN)

TBF those questions could also be answered by inspecting $FLOX_ACTIVE_ENVIRONMENTS which also provides a bit more information on what type of environment is active:

❯ flox activate --                                         
flox [cli] 
❯ echo $FLOX_ACTIVE_ENVIRONMENTS 
[{"type":"dot-flox","path":"/Volumes/Projects/Flox/flox/flox/cli","pointer":{"name":"cli","version":1}}]

I guess a flox status command should be not more than a pretty printer for that variable

consider adding a tip about exiting if we do flox status
