Instead of iterating over lines and tokens (and find comments between
tokens in the comment rules), add a new `Comment` type and set rules
with `type = 'comment'`.
Currently importing yamllint recursively imports its submodules, which
finally requires having pyyaml installed. This is a problem when you
just want to import APP_VERSION from yamllint. For instance, setup.py
imports yamllint to know the version, but doesn't know yet that pyyaml
is to be installed, because it is stated in setup.py itself.
To solve this, yamllint/__init__.py will only contain constants. The
linting functions will be in yamllint/linter.py.
YAML content like the following one produced an error, because the
multi-line ScalarToken ends at the beginning of the 4th line (the one
with the value):
? >
multi-line
key
: value
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
