Switch to @gustavnikolaj/async-main-wrap

[papandreou]

Gets rid of the arbitrary division of labor between lib/cli.js and lib/subfont.js and allows testing the command line options (instead of an unexposed programmatic API) without executing the binary in the test suite -- including the ability to mock out the network.

Also implement --dryrun and --silent.

💛 - Coveralls

[papandreou]

The drop in coverage % must be due to the removal of well-tested boilerplate code.

@Munter, any thoughts?

[gustavnikolaj]

There's a new version 3.0.0 that is just some neater output in error cases by default. :-)

[papandreou]

@gustavnikolaj, cool! I updated to that now.

[Munter]

I guess we can do this. Feels a bit ugly that all the conversion of arguments into cleanly applying options are now in the same file though. I'd prefer if we can keep the args to options conversion separated

[papandreou]

Cool, we can think about cutting that differently. As long as we get to make tests for the tool as a whole I’m happy :)

[papandreou]

As long as main.js isn't more lines than it is I actually think it's fine to have it all in one file. I'll merge for now, then we can see where it takes us :)
