Basically, any character is now allowed after the shebang marker.
Closes#428.
Whitespace after the #! marker on shebang lines is authorized and
optional, as explained on Wikipedia's entry for shebang line as can be
seen from the extracts below :
> White space after #! is optional
and
> It has been claimed[20] that some old versions of Unix expect the
> normal shebang to be followed by a space and a slash (#! /), but this
> appears to be untrue;[21] rather, blanks after the shebang have
> traditionally been allowed, and sometimes documented with a space
PyYAML implements YAML spec version 1.1, not 1.2. Hence, values starting
with `0o` are not considered as numbers: they are just strings, so they
need quotes when `quoted-strings: {required: true}`.
>>> import yaml
>>> yaml.resolver.Resolver().resolve(yaml.nodes.ScalarNode, '100', (True, False))
'tag:yaml.org,2002:int'
>>> yaml.resolver.Resolver().resolve(yaml.nodes.ScalarNode, '0100', (True, False))
'tag:yaml.org,2002:int'
>>> yaml.resolver.Resolver().resolve(yaml.nodes.ScalarNode, '0o100', (True, False))
'tag:yaml.org,2002:str'
Let's try to prevent that.
Fixes https://github.com/adrienverge/yamllint/issues/351.
We'd like to disallow brackets and braces in our YAML, but there's a
catch: the only way to describe an empty array or hash in YAML is to
supply an empty one (`[]` or `{}`). Otherwise, the value will be null.
This commit adds a `non-empty` option to `forbid` for brackets and
braces. When it is set, all flow and sequence mappings will cause errors
_except_ for empty ones.
Add 'forbid' configuration parameters to the braces and brackets rules
to allow users to forbid the use of flow style collections, flow
mappings and flow sequences.
Pound-signs followed by a lone CRLF should not
raise if require-starting-space is specified.
If require-starting-space is true, *and* either:
- new-lines: disbale, or
- newlines: type: dos
is specified, a line with `#\r` or `#\r\n` should
not raise a false positive.
This commit also uses a Set for O(1) membership testing
and uses the correct escape sequence for the nul byte.
If we find a CRLF when looking for Unix newlines, yamllint
should always raise, regardless of logic with
require-starting-space.
Closes: Issue #171.
Add ability to:
- require strings to be quoted if they match a pattern (PCRE regex)
- allow quoted strings if they match a pattern, while `require:
only-when-needed` is enforced.

The rule worked for values like:
flow-map: {a: foo, b: "bar"}
block-map:
a: foo
b: "bar"
But not for:
flow-seq: [foo, "bar"]
block-seq:
- foo
- "bar"
Also add tests to make sure there will be no regression.
Fixes: #208.
Make sure values passed in allowed values are correct ones. This is
possible thanks to previous commit, and should prevent users from
writing incorrect configurations.
Allows using key `allowed-values` for `truthy` section in configuration file (#150).
This allows to use configuration `truthy: allowed-values: ["yes", "no",
"..."]`, to set custom allowed truthy values.
This is especially useful for people using ansible, where values like
`yes` or `no` are valid and officially supported, but yamllint reports
them as illegal.
Implemented by difference of set of TRUTHY constants and configured
allowed values.

Some usages of YAML (like Ansible) supports running the file as a script.
Support (by default) an ignore-shebangs setting for the comments module.
Fixes#116 - comments rule with require-starting-space: true should special case shebang
Original implementation was completely broken. Documentation and actual
behavior were different. Numbers and booleans were detected as wrong, as
well as explicit types.
Fixes#136 and #130.
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).
With this change, we don't require quotes for truthy values that are
explicitly typed. For instance, the following examples are all
considered valid:
string1: !!str True
string2: !!str yes
string3: !!str off
encoded: !!binary |
True
OFF
pad== # this decodes as 'N\xbb\x9e8Qii'
boolean1: !!bool true
boolean2: !!bool "false"
boolean3: !!bool FALSE
boolean4: !!bool True
boolean5: !!bool off
boolean6: !!bool NO
With `allow-non-breakable-inline-mappings` enabled, every long line is
passed through `loader.peek_token()`. Even lines that are not valid
YAML. For this reason, this code must be wrapped in a `try`/`except`
block.
Closes: #21
