Previously only comments that were indented like the following content
line were allowed, e.g.:
prev: line:
# commented line
current: line
With this change, such new cases are also allowed:
prev: line
# commented line 1
# commented line 2
current: line
When both a syntax error (unability to parse a document) and a cosmetic
yamllint problem are found at the same place, the yamllint problem had
the priority -- and the syntax error was not displayed.
This had the following problem: if a rule is at the 'warning' level, its
problems will not make the `yamllint` script return a failure return
code (`!= 0`), even when it should (because there was a syntax error,
precisely).
This commit changes this behavior by preferring yamllint problems only
when they have the 'error' level.
`yaml.load()` exceptions are not necessarily syntax errors. For
instance, the following YAML source cannot be `load()`ed into a Python
object, but is valid nonetheless:
? - Detroit Tigers
- Chicago cubs
:
- 2001-07-23
? [ New York Yankees,
Atlanta Braves ]
: [ 2001-07-02, 2001-08-12,
2001-08-14 ]
This commit detects syntax errors from `yaml.parse()` exceptions rather
than `yaml.load_all()`.
