Commit c268a82 "key-duplicates: Don't crash on redundant closing
brackets or braces" fixed a problem but introduced another one: it
crashes on systems with (I guess) an old version of PyYAML. This is
probably linked to the "Allow colon in a plain scalar in a flow context"
issue on PyYAML [1].
For example, this problem happens on CentOS 8:
FAIL: test_disabled (tests.rules.test_key_duplicates.KeyDuplicatesTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):
File "…/tests/rules/test_key_duplicates.py", line 90, in test_disabled
'{a:1, b:2}}\n', conf, problem=(2, 11, 'syntax'))

self.assertEqual(real_problems, expected_problems)
AssertionError: Lists differ: …
- [2:3: syntax error: found unexpected ':' (syntax)]
+ [2:11: <no description>]
I propose to simply fix the *space following a colon* problem, since
it's not related to what the original author @tamere-allo-peter tried to
fix.

- Add a `temp_workspace` context manager to simplify writing new tests.
- Add `# pragma: no cover` to unit test code paths used for skipping tests.
These code paths are only covered when tests are skipped.
That makes it impractical to reach full code coverage on the unit test code.
Having full coverage of unit tests is helpful for identifying unused tests.
- Test the `octal-values` rule with a custom tag.
- Test the cli `-d` option with the `default` config.
- Test support for the `XDG_CONFIG_HOME` env var.
- Test warning message output.
- Test support for `.yamllint.yml` config files.
- Test support for `.yamllint.yaml` config files.
- Test error handling of a rule with a non-enable|disable|dict value.
- Test error handling of `ignore` with a non-pattern value.
- Test error handling of a rule `ignore` with a non-pattern value.
- Test error handling of `locale` with a non-string value.
- Test error handling of `yaml-files` with a non-list value.
- Test extending config containing `ignore`.
- Test `LintProblem.__repr__` without a rule.
- Test `LintProblem.__repr__` with a rule.
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.
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.
Fixes#325
The linter allows a directive to contain trailing whitespace characters like
\r, but does not trim them before iterating on the rules. As a result, the last
rule in the list contains the trailing whitespace characters and never matches
any existing rule.
I added the necessary trimming, as well as a test with 2 checks to go along
with it.
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.
Use io.open() when reading files in cli which has the same behaviour
in Python 2 and Python 3, and supply the newline='' parameter which
handles but does not translate line endings.
Add dos.yml test file with windows newlines.
Also add to file finding test expected output.
Add test for new-lines rule through the cli.
Validates files are read with the correct universal newlines setting.
Fixesadrienverge/yamllint#228
Single context manager that includes exit code and output streams.
Use new RunContext throughout test_cli.
Largely non-functional change, saving some repetition of setup.
Also improve some failures by bundling multiple assertions into one.
