Addresses issue #432 by adding a noArrayIndent option to optionally not add an extra level of indentation to array elements.

When noArrayIndent option is set to false (or not provided), output is:

array:
  - a
  - b
  - c

When noArrayIndent option is set to true, output is:

array:
- a
- b
- c

This helps avoid diffs when parsing, modifying, and generating valid yaml that does not use extra indentation for arrays.

Defaulting to true to maintain backwards-compatibility.

The package lock should either be committed or ignored. Seeing as it isn't committed, I'm ignoring it.

I'd suggest noArrayIndent instead of such logic.

@puzrin I have completed all requested changes, and squashed all the commits down to a single commit as requested. Thanks

FYI: I highly recommend you use "squash merges" functionality in the repository settings, rather than requiring contributors to rewrite history on their feature branches.

Thanks! I know about "squash merges". But it just more convenient for review to to collapse long tail of commits, when only couple of files affected.

@jacob-hd could you take a look at #468 (comment)?

Seems indents become broken when top level array contains objects

puzrin commented Apr 24, 2019

@jacob-hd

node -e "console.log(require('js-yaml').dump({ test: [[1, 2], [3,4]]}, { noArrayIndent: true }))"

=>

- - 1
- 2
- - 3
- 4

One more example of bad behaviour. Seems initial PR has not enougth nested samples.

Following on from what @puzrin said about the issue with noArrayIndent, the following also does not work:

node -e "console.log(require('js-yaml').dump({ test: [1, 2, 3, 4]]}, { noArrayIndent: true }))"

=>

test:
  - 1
  - 2
  - 3
  - 4

vs expected

test:
- 1
- 2
- 3
- 4

I suspect that the issue might be resulting from an earlier fix by @diberry (namely https://github.com/diberry/js-yaml/commit/18a871cf69435309598393be86006e39abc9d492), where the level should be >= 0, rather than just > 0, but I am not entirely sure. Just trying to provide a pointer :)
