Description

[Description of the issue]

YAML highlighting for a key's value continues onto the next line when it is a simple, non-quoted string (not a list, another key, a multiline string (with | or >), etc, and the highlighting should not continue.

Simple test case in YAML file to reproduce

this: key
is
highlighted
over
arbitrary
number
of
lines

Expected behavior: [What you expect to happen]
When using a simple, non-quoted string in YAML, I expect the next line's content to not be highlighted unless it is a quoted string, a list, a multiline string (with | or >), etc. In the example, 'is' begins a line that violates YAML's syntax. One suggestion that this case is the correct one is that trying to load a test yaml file in Python with the text will throw an error with the text could not find expected ':' on the example line "is".

Actual behavior: [What actually happens]
YAML highlighting for a key's value continues onto the next line when it is a simple, non-quoted string (not a list, another key, a multiline string (with | or >), etc. See image below.

Reproduces how often: [What percentage of the time does it reproduce?]
Always

So yes, this is an issue. However, it is a very difficult issue to fix. I've made some (non-visible) progress with it in #74.

Thank you! I believe this issue is the root behind support for Jinja2 highlighting in YAML files: danielchatfield/atom-jinja2#22

Update: Just installed language-yaml 0.29, and YAML with Jinja now highlights properly. Thank you, @50Wliu !

I either have a similar or the same issue.

Syntax highlighting for a multiline string continues after the multiline string.

It happened very shortly after I updated all my atom packages, but I'm not sure what version I was on before.

➜  atom atom --safe
➜  atom atom --version
Atom    : 1.22.1
Electron: 1.6.15
Chrome  : 56.0.2924.87
Node    : 7.4.0
➜  atom apm --version
apm  1.18.8
npm  3.10.10
node 6.9.5 x64
python 2.7.13
git 2.11.0

I also moved all of my ~/.atom to ~/.atom-backup.

I have a similar issue, though it's also erroneously highlighting a hidden char (space)

Atom    : 1.23.3
Electron: 1.6.15
Chrome  : 56.0.2924.87
Node    : 7.4.0
