Move PNG generation library code into a separate package and remove autodetection of dataDir

[sqs]

This PR makes it possible to use buckler as a library.

Buckler is awesome, BTW!

@nathany Wanna review this PR?

[nathany]

@sqs Can you look into why the Travis CI build is failing?

I can review this after the holidays. Thanks.

[sqs]

Will do

I think the Travis CI build is failing because it's set up for jbowes/buckler, not gittip/img.shields.io. If that's not the proximate cause, then it makes it difficult to debug because clicking on the Details link above yields a page that just says "Loading."

I don't see this PR at https://travis-ci.org/gittip/img.shields.io/builds, but I think one of the repository owners could trigger a build of this PR over at that link. Then I will diagnose the issue.

[chadwhitacre]

@sqs I restarted the build using gittip/img.shields.io. The build did error, but the "Details" link here now gives more useful output.

#25 should help matters

[nathany]

I don't believe Go supports relative import paths. You'll need github.com/gittip/img.shields.io/shield.

[nathany]

@sqs I'm still brand new to this code base, but I'm not sure about deleting that resources.go code. Maybe resourcePaths() should still be used by main.go even if it's not used by the shield subpackage. Perhaps @jbowes can chime in on these changes.

[nathany]

@sqs #25 got Travis passing on master. It does introduce a small merge conflict (basePkg) for you to address. Thanks.

[sqs]

Great. Thanks for the CR and the other fixes. I'll push some changes to this PR to address these issues in a couple of hours.

[sqs]

OK, I pushed changes that address these comments and bring this branch up-to-date with master. Travis CI is now passing.

Regarding resourcePaths(), I personally find it simpler to be explicit about paths instead of guessing them according to convention. The old convention in resourcePaths() would only work if you run it with go run or if you copy the data/ and static/ dirs into your $GOBIN. I'm fine with either way, though, so let me know what you prefer. (Either way, it needs more changes; currently, staticDir is hard-coded and dataDir is specified via command-line option, and it only makes sense for both to be determined in the same way.)

[sqs]

This will need to change per badges/shields#90 (comment)

[nathany]

Rather than having a shield subfolder, what do you think of flipping it around? Go stdlib and a few other places have a cmd folder.

so github.com/badges/buckler/cmd/buckler is the folder containing the buckler CLI.
so we could make github.com/badges/buckler the library import (stdlib actually has a pkg/ subfolder as well, but meh).

Also, let's just call this buckler (not shield).

[sqs]

sgtm!

[nathany]

Thanks @sqs.

Should there be some changes to the Command Line section of the README regarding resources?

We should also add a section on using it as a library, though it's going the be unstable for a bit as we rename repos and rearrange things again.

Hopefully @jbowes can take a look before we hit the big green button, just in case there's something we missed.

[sqs]

@nathany, yes, good point, we will need to update the README to describe the -d option, but I want to wait until it's decided whether we use -d or the previous discovery method (#13 (comment)). You or @jbowes can make the call. And I'll add library usage info to the README then, tooo.

[nathany]

@sqs Also check the discussion here. badges/shields#94 Everything's up in the air atm.

[nathany]

So I guess I'll do another bit of cleanup now that we've relocated once again.

[sqs]

Sounds like buckler won't be used by shields.io anymore, so this may be a moot point, right? (Re: badges/shields#90 (comment))

[nathany]

Yah. We'll see how that goes. What were your plans for the buckler library?
