withenv: runs processes with environment settings from a file

It's just like envdir, but for go, and it reads files.

Goals

When I looked around, I couldn't find a tool for a small need: to run an application quickly with appropriate environment variables set, when no shell is available.

This particular use case helps running handlers in sensu-go, while secrets are not exposed to the API / web UI. Information about a file on a system is less threatening than seeing the actual secret set by an environment variable, which is not even redacted by the user interface.

Legal

This project is licensed under Blue Oak Model License v1.0.0. It is not registered either at OSI or GNU, therefore GitHub is widely looking at the other direction. However, this is the license I'm most happy with: you can read and understand it with no legal degree, and there are no hidden or cryptic meanings in it.

The project is also governed with Contributor Covenant's Code of Conduct in mind. I'm not copying it here, as a pledge for taking the verbatim version by the word, and we are not going to modify it in any way.

Any issues?

Open a ticket, perhaps a pull request. We support GitHub Flow. You might want to fork this project first.
