Why is it necessary to activate with `. <(flox activate)`?

etorreborre · November 8, 2022, 9:57pm

I installed an executable, cmt, to both the default and the haskell environments. When I try to activate the haskell environment with just flox activate -e haskell, I don’t access its corresponding cmt executable:

○ which cmt
/Users/etorreborre/.local/share/flox/environments/etorreborre/default/bin/cmt

○ flox activate -e haskell

○ which cmt
/Users/etorreborre/.local/share/flox/environments/etorreborre/default/bin/cmt

○ . <(flox activate -e haskell)

○ which cmt
/Users/etorreborre/.local/share/flox/environments/etorreborre/haskell/bin/cmt

I am using zsh and I actually don’t know what . <(flox activate -e haskell) does differently than just flox activate -e haskell.

The topic of activation is discussed in the floxdocs Using Environments section, but in short:

when invoked from a controlling terminal (i.e. interactively), flox activate will start a subshell populated with all the necessary environment variables
when invoked without a controlling terminal (i.e. from a .zprofile as you first log in), flox activate will emit the commands required to populate the necessary environment variables using the appropriate commands for your shell language

If that doesn’t make sense, then perhaps this example will?

[brantley@clubsoda:~/src/flox-internal]$ flox activate -e testing | grep testing
export FLOX_PATH_PREPEND="/home/brantley/.local/share/flox/environments/limeytexan/testing/bin"
export FLOX_ACTIVE_ENVIRONMENTS="/home/brantley/.local/share/flox/environments/limeytexan/testing:/home/brantley/.local/share/flox/environments/limeytexan/default"
export FLOX_PROMPT_ENVIRONMENTS="testing default"

[brantley@clubsoda:~/src/flox-internal]$ flox activate -e testing 

flox [testing default] [brantley@clubsoda:~/src/flox-internal]$ env | grep testing
FLOX_PROMPT_ENVIRONMENTS=testing default
FLOX_ACTIVE_ENVIRONMENTS=/home/brantley/.local/share/flox/environments/limeytexan/testing:/home/brantley/.local/share/flox/environments/limeytexan/default
PATH=/home/brantley/.local/share/flox/environments/limeytexan/testing/bin:/home/brantley/.local/share/flox/environments/limeytexan/default/bin:/run/wrappers/bin:/home/brantley/.nix-profile/bin:/etc/profiles/per-user/brantley/bin:/nix/var/nix/profiles/default/bin:/run/current-system/sw/bin

flox [testing default] [brantley@clubsoda:~/src/flox-internal]$

Let me know if that helps - thanks!

It is still not clear to me why, when I open a zsh session and type flox activate -e haskell I don’t see /Users/etorreborre/.local/share/flox/environments/etorreborre/haskell/bin: prepended to my PATH variable but I still see the default one.

The example in the subshell section seems to do exactly that:

$ flox activate -e work
[flox] $ which vim
/home/floxfan/.local/share/flox/environments/local/work/bin/vim

When I do something similar I get

○ echo $PATH
/Users/etorreborre/.local/share/flox/environments/etorreborre/default/bin:/opt/homebrew/bin:/Applications/google-cloud-sdk/bin:/Users/etorreborre/.ghcup/bin:/Users/etorreborre/.cabal/bin:/Users/etorreborre/.local/bin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Library/Apple/usr/bin:/usr/local/opt/fzf/bin:/Users/etorreborre/.symbiont/versions/current/bin

~
○ flox activate -e haskell

~
○ echo $PATH
/Users/etorreborre/.local/share/flox/environments/etorreborre/default/bin:/opt/homebrew/bin:/Applications/google-cloud-sdk/bin:/Users/etorreborre/.ghcup/bin:/Users/etorreborre/.cabal/bin:/Users/etorreborre/.local/bin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Library/Apple/usr/bin:/usr/local/opt/fzf/bin:/Users/etorreborre/.symbiont/versions/current/bin

Also I don’t understand why when executing . <(flox activate -e haskell) then my PATH variable magically gets prepended with the content of FLOX_PATH_PREPEND.

In terms of usability it is a bit problematic to me because it means that if I want to switch to an environment containing a specific executable I need to remember to use the longer form . <(flox activate -e env).

Finally I can see that a FLOX_PROMPT_ENVIRONMENTS variable is available. I guess that the idea is to use it to enrich the current prompt with the flox environments. I need to check how to do this with zsh :-).

etorreborre · November 8, 2022, 10:52pm

For now I added this to my .zshrc file and it shows the current environment on the right of my screen:

RPROMPT='%F{green}${FLOX_PROMPT_ENVIRONMENTS%" default"}%f'

Sorry this isn’t working for you as expected. Can I just confirm you’re using the latest version? The example you show above has a prompt containing “[flox]” and the latest version does not do that.

Here’s the latest version on darwin:

flox  [default] brantley@Michaels-MBP flox-internal % flox upgrade flox.flox-prerelease
upgrading 'evalCatalog.aarch64-darwin.stable.flox-prerelease' from flake 'github:flox/floxpkgs/aa643781031957c0403f52a2aed718930f359dfc' to 'github:flox/floxpkgs/964b0e39ade4d0bb645ab64dae85197ab61d7b61'
flox  [default] brantley@Michaels-MBP flox-internal % flox --version
Version: 0.0.6-r58
flox  [default] brantley@Michaels-MBP flox-internal %

(x86_64-darwin should be the same version)

Once you’re sure you’re using the latest version, please include the full output of flox -v activate -e haskell so we can see what it’s doing. I’m also happy to hop on Discord if this is easier to debug in real time.

Many thanks!

The example with [flox] is actually taken from the documentation :-).

In that session I:

upgrade flox
print the PATH
activate the haskell environment
notice that there is now a prompt with the list of active environments
print the PATH, the haskell/bin path does not come first
try to go back to default, eventually calling exit as I should
reactivate -e haskell with -v
try to echo $PATH → the verbose output is still on, something to fix for you
check that an executable, hpack, is listed under the haskell environment
do a which hpack and realize it is found under /Users/etorreborre/.local/bin/hpack

By the way, in case you don’t know about that, I was surprised to learn that zsh was caching the path to some executables. So sometimes it can appear that zsh does not find the first executable on the PATH: zsh - Under what circumstances will the executable first found in the path not be used - Unix & Linux Stack Exchange.

This is a common problem with various environment managers. For example, python does this bit here: venv: Suppress warning message when bash hashing is disabled. by d-goldin · Pull Request #17966 · python/cpython · GitHub

Perhaps we automatically add that to all activations, for the same reason.

@etorreborre - just double checking to see if we’ve missed any outstanding questions with this thread?

My PATH doesn’t seem to be properly updated. Maybe I don’t have the latest flox version?

Right now I am still a bit confused about what is the right set-up with .zshrc and what is the right command to use. Ideally I would:

add a line in .zshrc to put me in the default environment
run flox activate -e rust to select the rust environment
check my PATH and see that rust/bin comes first

limeytexan · November 20, 2022, 10:50am

Yes - that’s the idea and absolutely correct. If I can ask one further favour could you do the following:

Compare the behaviour of flox activate -e rust (interactive) vs. . <(flox activate -e rust) (non-interactive). Are they both broken in the same way?
Whichever one(s) of the above are broken, can you add the --debug flag and send me the output? E.g. . <(flox --debug activate -e rust)

I’ll be online later today if you would like to work on this in real time. As ever, many thanks for the feedback!

The ... stand for debug information which was displayed as the result of using --debug before (I already mentioned that issue somewhere)

Now the session that works has a small bug with the --debug flag:

○ . <(flox --debug activate -e rust)
trace:/nix/store/clm98qbm57nc2wpww2jg6rgn20nwkhbs-flox-prerelease-0.0.6-r58/lib/utils.sh:139 hash_commands( ansifilter awk basename bash cat chmod cmp column cp curl cut dasel date dirname id jq getent gh git gum grep ln man mkdir mktemp mv nix nix-store parallel pwd readlink realpath rm rmdir sed sh sleep sort stat tail touch tr uuid xargs zgrep )

/dev/fd/11:1: parse error near `)'

but if I just go

○ . <(flox activate -e rust)

then my PATH is ok:

○ echo $PATH                                                                                                                                                                                                                                                               rust

(except maybe for the duplicated default/bin but it is harmless)

We can jump on an online session now if you have a moment.

sorry guys but I’ve kinda lost the plot on this one. Was this resolved offline? If not, @etorreborre - could you please summarise your outstanding queries so I can follow up?

etorreborre · November 30, 2022, 3:50pm

My understanding is that the team is aware of this issue and is working on it. And I thought that 0.7.0 would bring an answer. Isn’t that the case?

robinbrantley · November 30, 2022, 4:42pm

thank you for that update as I was trying to figure out if the outstanding issues were indeed going to be sorted with the next release (0.0.7) or if there was something further to be sorted for you. Michael has just confirmed to me the issues raised in this thread are addressed in the next release. yay!

The release is expected out soon and will be announced in discourse.

limeytexan · December 2, 2022, 10:51am

Thanks again @etorreborre for being patient with us! Version 0.0.7 included an overhaul of the environment activation code which should have fixed all the issues documented in this thread. Speaking to you offline I understand everything is now working for you - if you find that changes at any point please let us know!

Why is it necessary to activate with `. <(flox activate)`?
