<div dir="ltr"><div>I considered the same thing with an existing GOBIN env var. I did actually test it and found it worked as expected. Items earlier in the list seem to have higher priority. I prefer not to use setenv, because I want to exec into the binary later without GOBIN clobbered, which means keeping the current environment pristine. Good point about it not matching the Python version, but then a few other things don't either now. :)</div>

Is there someway to get the current directory without having to store the action the way that I am doing? <$> would work if the current directory was the last argument to the joinPath, but here it's the first.</div>

It's a really nice library / DSL for "bash"-like scripting directly in Haskell. If you try out Shelly, I suggest trying it with ClassyPrelude and -XOverloadedStrings, which makes dealing with all the Text and FilePath types bearable. (Heh, though it's annoying, having FilePath as a separate type once prevented me from writing code that deleted my home directory upon being run... fun story.)<div>
