Simplify conditonal build steps

[epage]

Examples

• Build step on only on a given channel
• Build step if a env variable is set to X

[epage]

cargo-when is a good candidate for this

cargo when --channel stable,beta build

Unfortunately, it doesn't seem to be getting any love. Desired work

• pre-built binaries
• environment support

I reached out to the author for joining effort (starkat99/cargo-when#2) but haven't heard back.

The repo hasn't been touched in 2 years but the author is still active on github.

CAD97 pointed this out to me, seems interesting: http://cs.furman.edu/~cdurham/experiments/Rust/ci_detective/

@CAD97 should some of the conditional steps you've adding to ghp-upload be integrated into this tool?

[CAD97]

Yes, that's why I'm writing it :) (that's my school webserver, I also could have put it on cad97.com but didn't feel like it)

It's still very much in experimentation phase. But it should allow further CI tools to build on top of it without having to do the doc-crawling of various CI environment setups that I'm doing right now.

Just to be clear, the idea here is make a command line tool (one exists; trying to reuse it) So instead of baking the CI policy into ghp-upload for when to run, you pass conditions to this wrapper. it then decides when to invoke your tool.
