Hi all, is it possible to write such a macro or a plugin which loads some information into an env var and then other BUILD files could use that var, for example, add this env var as a tag for a docker image, pass this env var to tests, etc.?

I’m not sure I know the answer, but I can ask some clarifying questions: • Do you need it as an env var specifically? • What sort of information?

I want it to be available in a docker tag. It's information about the project version

One option might be a shell script called

.pants.bootstrap

adjacent to your

pants.toml

. This is executed before each pants run and, I believe, can set environment variables like

export VERSION=…

. That said, it sounds like you may already have that env var set, so can you pass it as

image_tags=[env(…)]

?

We have .env, but we have to run script to generate it before we execute pants commands

Yes

Cool, I'll try it, thanks
