dev env cd run commands

I really like that I can cd into a directory and have packages and env vars in scope.

In the case of a package like postgres it would be nice to be able to start and stop this when moving in and out of a directory also.

This could be done by parsing this from the config:

dependencies: [email protected] [email protected]
env:
  DB_HOST: localhost
  DB_NAME: postgres
  DB_PORT: 5433
  DB_USER: postgres
commands:
  in:
    - make db_start
    - make db_migrate
  out:
    - make db_stop

This would shell out to run these commands once the deps and env have been loaded. Then just print out any messages or errors from these commands.

it could be done that way, but then you have to worry about random code running whatever on your computer. there's ways around it (direnv allow for example), but a more friendly way is probably to use a tool like just or xc (both packaged for pkgx) to have your environment commands quick to hand.

[atomraymaker]

yeah, it did seem like it might be a step too far, but convenient. Maybe one of these other tools can easily work alongside. I couldn't even get direnv to work with nix and pkgx does what I wanted from that on cd.

[atomraymaker]

it would be nice if pkgx loaded direnv and then direnv ran but since direnv is expecting to be integrated before the cd I don't know if it will work that way.

I think we would prefer to delegate to direnv for this yeah. At least for now anyway. We're trying to remain tightly scoped.

But you say direnv won't work? Can we fix that?

[atomraymaker]

I will see how it works when I get it set up. I am just looking to be able to cd into a directory and have the dev env all ready to use. I don't know how pkgx and direnv will work together to do that without extra steps but I will see what I can get working.
