See issue #3271 for a motivation of this feature.
This patch adds an additional text input to the advanced view of the password generator. All characters of this input field (if not empty) will be added as another group to the password generator. The characters from the excluded field have precedence over the characters from this new field, meaning any character added to both fields will *not* appear in any generated password. As the
characters from this new field will be added as their own group to the password generator, checking the 'Include characters from every group' checkbox will
force at least character to be chosen from the new input field.
The `PasswordGenerator` class has also been changed so that the `isValid` method returns `true` if only characters from the new input field would be used.
There is a new, simple test that covers the new feature. While the test only uses ASCII characters, any Unicode characters can be used with the new feature.
Many lines were not conformant with the project's formatting rules.
This patch should fix all formatting and whitespace issues in the code
base.
A clang-format directive was put around the connect() calls containing
SIGNALs and SLOTs whose signatures would be denormalized because of the
formatting rules.
The CLI module was lacking unit test coverage and showed some severe
coding style violations, which this patch addresses.
In addition, all uses of qCritical() with untranslatble raw char*
sequences were removed in favor of proper locale strings. These are
written to STDERR through QTextStreams and support output
redirection for testing purposes. With this change, error messages don't
depend on the global Qt logging settings and targets anymore and go
directly to the terminal or into a file if needed.
This patch also fixes a bug discovered during unit test development,
where the extract command would just dump the raw XML contents without
decrypting embedded Salsa20-protected values first, making the XML
export mostly useless, since passwords are scrambled.
Lastly, all CLI commands received a dedicated -h/--help option.
