Add `pipx hook` command

Hi! Thank you for this fabulous tool!

How would this feature be useful?

Conda offers a command conda shell.{bash|zsh|fish} hook which can be invoked from scripts to bring the Conda environment into the current shell.

The boilerplate Conda adds to rcfiles actually invokes this command! But it’s also useful for scripts which install a sequence of tools (Conda, pipx, Poetry) to bootstrap a developer’s Python environment, with minimal interaction on their part.

I’m running pipx ensurepath from my bootstrap script, however it doesn’t take effect until starting the next shell. Starting a new shell is a rather clunky thing to do in the middle of a shell script execution.

Describe the solution you’d like

A pipx hook {bash|zsh|fish} command which outputs set -x PATH $PATH /Users/pnm/.local/bin or something similar, which updates and exports PATH in the current shell.

Another alternative (a little less nice I guess) would be a command like pipx bindir which resolves pipx’s config and just prints /Users/pnm/.local/bin.

Describe alternatives you’ve considered

My workaround is to hard-code ~/.local/bin in my bootstrap script. This works, however I’d have more confidence using a pipx command since I know it will honor pipx’s config. It also makes the intention of my bootstrap script more self-documenting.

That makes sense, thanks. Would you be interested in contributing such a command? I feel we can extend the idea to something like pipx environment, pipx constants, or something like that (I’m not good at naming things). This would print the variables pipx uses in pipx.constants, such as PIPX_HOME, PIPX_SHARED_LIBS, and PIPX_BIN_DIR (the last is the one you’re looking for). The format can be something like

$ pipx environment
PIPX_HOME=/home/user/.local/pipx
PIPX_SHARED_LIBS=/home/user/.local/pipx/shared
PIPX_BIN_DIR=/home/user/.local/bin

and we can maybe have an option to print a specific value like

$ pipx environment --value=PIPX_BIN_DIR
/home/user/.local/bin

Not sure what best to design this, other ideas are definitely welcomed.

Hi @uranusjr, I am going to implement this. 👍
