Target selector

[dschwen]

Adds a target selector to choose a valid make target:

This runs make and obtains a list of valid targets. It supports arbitrarily complex makefiles (e.g. include directives that generate targets and variable targets).

Replaces #35

I'm putting this out here for comments. There is a little more work to do to correctly deal with abort and running make while the target list is obtained

Whatever happened to this PR...

I never merged it because it was marked as wip 🤣

Are you ready for it? I'm going to have to figure out how to publish this too.

[dschwen]

Let me see if this still rebases cleanly and rethink what I meant by "There is a little more work to do to correctly deal with abort and running make while the target list is obtained". Good to see you're still around :-)

Sounds good and of course! I'm working on a competing product, but definitely keeping this alive. :)

[dschwen]

Ok, this PR seems fine. What's the competing product?

Oh, you work on VSCode! Yeah, I've started looking at that as well. But I'm so deeply invested in the Atom plugin ecosystem (with a smart autocomplete for an open source finite element framework) that I'm dreading to relearn the VSCode plugin system.

Intellisense would be nice to have though.

And it's published! Fun fact: apm uses the repository field in package.json to publish the tag and if it doesn't like that format, you get a misleading error. 😅

Let me know if you'd ever like to dig into the extension API in VS Code. The getting started docs are quite good. 😊
