I'd call this file "packages_file_test". Also, since it's not specific to "pub
get", I'd move it to "test/" and run it in "forBothPubGetAndUpgrade".

Remove this. Some old tests have it, but new tests shouldn't.

[Lasse Reichstein Nielsen, 2015/06/11 11:21:03]

Done.

Update the test name.

[Lasse Reichstein Nielsen, 2015/06/11 11:21:02]

Done.

We don't do argument alignment like this. It'll also definitely create noise if
we ever run the formatter over this code.

[Lasse Reichstein Nielsen, 2015/06/11 11:21:02]

Arguments fixed to match formatter.

The d.dir below gets completely fouled up by formatter, though.

[nweiz, 2015/06/12 23:48:08]

Yeah, I think Bob is working on better support for argument lists mixed with
collections right now.

[Bob Nystrom, 2015/06/12 23:49:15]

Yup. It's landed on master in the dart_style repo now. I'll try to get a release
out next week.

[nweiz, 2015/06/10 22:33:59]

This should contain a link back to the application itself.

[Lasse Reichstein Nielsen, 2015/06/11 11:21:03]

True. Updating test to check fail if there are more declarations than expected.
