The `# -*- coding: utf-8 -*-` headers were useful for Python 2, and
aren't needed for Python 3 where UTF-8 is the default.
yamllint support of Python 2 was dropped in early 2021, see commit
a3fc64d "End support for Python 2".
Let's drop these headers.
If a key-value pair follows an empty list, i.e.:
```yaml
a:
-
b: c
```
yamllint will complain:
```
warning wrong indentation: expected 2 but found 0 (indentation)
```
This is because it is expecting the second key to be a continuation of
the block entry above:
```yaml
a:
-
b: c
```
However, both are perfectly valid, though structurally different.
In the case when the conf is as follows:
indentation:
spaces: consistent
indent-sequences: true
and there is no indented block before the first block sequence, and this
block sequence is not indented, then the spaces number is computed as
zero (while it obviously shouldn't be).
This causes such a document to fail on 4th line, instead of 2nd:
a:
- b
c:
- d
This commit fixes that, and adds corresponding tests.
Fixes: #39
Although `yes` and `no` are recognized as booleans by the pyyaml parser,
the correct keywords are `true` and `false` (as highlighted by the newly
added `truthy` rule).
This commit replaces the use of `yes`/`no` by `true`/`false` and
advertise it in the docs, but also makes sure this change is
backward-compatible (so that `yes` and `no` still work).
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'`.
The following source -- although not loadable by pyyaml -- is valid
YAML:
{{key}}: value
This was processed badly by yamllint. The same for `[[value]]`,
`{{{{{moustaches}}}}}` or:
{[val,
{{key: val,
key2}}]}
This patch corrects it and add corresponding test cases.
Related-to: #3
The "indentation stack" is iteratively built by the `check()` function
of the indentation rule. It is important, since everything in the rule
relies on it.
This patch adds tests to make sure the stack is correctly built for some
known structures.
For strings that continue on next line at a lower indentation level:
Blaise Pascal: Je vous écris une longue lettre parce que
je n'ai pas le temps d'en écrire une courte.
This options allows the user to control whether to lint indentation
inside multi-line scalars or not.
When enabled, such YAML source will be detected as a problem:
- C code: void main() {
printf("foo");
}
whereas this one would not:
- C code: void main() {
printf("foo");
}
Using either 'yes', 'no' or 'whatever', the user will be able to choose
whether to force block sequence items to be indented, to force them not
to be indented, or don't care, respectively.
