tea -E analog for use in direnv?

[jasisk]

Hey there.

Was curious if there was a kosher way to replicate the behavior of tea -E in this new v1.0.0 world. Specifically, I was using the following direnv plugin to allow for dev env magic without magic:

use_tea() {
	direnv_load tea -E -- direnv dump
}

watch_file .tea.yml

Would something like this be legit and something not prone to breaking in the future?

use_pkgx() {
	direnv_load pkgx --internal.activate "${PWD}" -- direnv dump
}

watch_file .pkgx.yaml

This may break because yeah it's internal, but we can make a more formal way to do this which we then promise to keep.

What does direnv dump do?

Felt gnarly asking about using an internal flag so the potential for breakage is totally expected—frankly, just hoped it would help convey the question better.

Adding a formal method would be greatly appreciated—thank you!

direnv dump just (safely) serializes the env in a format that can be loaded by direnv_load.

Basically, this pseudocode:

const vars = getEnvVars();
const escapedVars = escapeKeysAndValues(vars);

return base64Enc(gzip(JSON.stringify(escapedVars)));

This seems like a neat thing to add to our docs, once we formalize the args to dev. Let me think about how to approach this and get back to you.

If folks wander in here looking for a solution while the api is considered, the following works just fine. direnv will just pass along the exported environment variables, not the functions or hooks. This does not use the direnv escaping bits provided by direnv_load and direnv dump but pkgx escapes the vars it exports and we're not reexporting anything else.

Warning

HUGE CAVEAT!
This is using an internal flag that has no guarantees of stability. This direnv plugin may break at any time and it's not pkgx / pkgx maintainer's fault.

As a result, I won't be marking this as an answer. Buyer beware. 😃

use_pkgx() {
	# THIS USES AN INTERNAL AND UNSUPPORTED FLAG
	eval "$(pkgx --internal.activate "${PWD}")"
}

watch_file pkgx.yaml .pkgx.yaml

usage in an .envrc file:

use pkgx
