At some places, the colour reset code is printed after a newline.
Since the default output buffering to console is line-based, the reset
code is not actually written out. If messages from user code are printed
to stderr (different stream, same console), they are printed before
the colour reset code, and thus they are coloured.
Explicitly flushing the stream after writing the colour escape code solves
this.
Most of the changes are completely pointless renaming of constructor
arguments so that they do not use the same name as the type members,
but 🤷Closes#2015
This commit also strips the old copyright comment header in touched
files, as those will also be replaced with a more standardized and
machine-friendly version.
The base was also renamed from `TestEventListenerBase` to
`EventListenerBase`, and modified to derive directly from the
reporter interface, rather than deriving from `StreamingReporterBase`.
Due to also adding a new TU, there is no improvement to the
compilation times of the static library, but it improves the
compilation times of consumer's reporter TUs.
Doing this removes `<map>` from the include set of the base reporter
interface, and thus from bunch more TUs. This provides about 1.5%
improvements in the debug build of the static library, and 1% in
release build.
Each of the two reporter bases now has its own header file, and
cpp file. Even though this adds another TU to the compilation,
the total CPU time taken by compilation is reduced by about 1%
for debug build and ~0.5% for optimized build of the main library.
(The improvement would be roughly doubles without splitting the TUs,
but the maintainability hit is not worth it.)
The code size of the static library build has also somewhat decreased.
Follow up: Introduce combined TU for reporters, and further split
apart the catch_reporter_streaming_base.hpp header into its
constituent parts, as it still contains a whole bunch of other stuff.
Anchoring the vtables does 2 things
1) Fixes some instances of `-Wweak-vtables`
2) Decreases code size and linker pressure
However, there are still some unanchored ones, and thus we have
to keep suppressing `-Wweak-vtables` warning for Clang.
* Added some missing `noexcept`s on custom destructors.
* Fixed `std::move` being called on a const-reference.
* Initialized `ScopedMessage::m_moved` in class definition, instead
of doing so in constructors explicitly.
* Turned some `enum`s into `enum class`es.
* Initialized `StreamingReporterBase::currentTestCaseInfo` in class
definition.
* Some cleanups in SelfTest code.
The includes were an artifact of the old design where the built-in
reporter TUs used autoregistration to add the reporters to the
factory. Because the current design is to add them explicitly in
the central reporter factory TU, the includes are useless.
This saves a tiny little bit of compilation times when the
`ApproxMatcher` is used and `epsilon`, `margin`, or `scale` are
used to customize its behaviour.
As the full `Config` is not needed, the TUs implementing the `list*`
functions can require the less heavy header `catch_interfaces_config.hpp`
instead of the much heavier `catch_config.hpp`.
This commit also fixes up some other TUs that include `Config`,
while using just `IConfig`, to cleanup the includes further.
* Clara is now split between a header and a cpp file.
* Removed the deprecated `+` and `+=` operators for composing
a parser.
* Renamed `clara` and `detail` namespaces to be inline with the
rest of Catch2 (they are now `Clara` and `Detail` respectively).
* Taken most of user-exposed types out of the `Detail` namespace
completely (instead of using `using` directives to bring them into
the outer namespace).
Now that it has its own header, various reporter TUs that want to
format text do not have to also include Clara. Together with
outlining implementations from a header into a separate TU, this
has noticeably improved the compilation times of the testing impl.
As part of this split, I also implemented some improvements to the
TextFlow code in comparison to the upstream code. These are:
* Replaced the `Spacer` type with a free function that constructs
special `Column` that does the same thing.
* Generic performance improvements, such as eliminating needless
allocations, reserving space in needed allocations, and using smarter
algorithms in some places.
* Because `Column` only ever stored 1 string in its vector, it now
holds the string directly instead.
This means that code that uses it no longer has to include all of
catch_config.hpp, which seems to provide significant reduction in
size of unoptimized compilation of the final static library.
This is not nearly all of them, because IWYU does not support the
way Catch2 manages includes -- it expects that non-system includes
are done using `#include "foo/bar/baz.hpp"`, while Catch2 uses
`<foo/bar/baz.hpp>`. This causes trouble, because IWYU suggests
removing every single internal header, and then adding them again,
but using `""` in the include directive... the resulting suggestions
cannot be used without a lot of manual work, as they are largely
bogus.
For bonus points, IWYU also _loves_ to suggest kinda-random stdlib
headers for `size_t` and similar. Still, the resulting inclusion
graph is somewhat better than it was before.
The new scheme is that there is one protected member instance of
`ReporterPreferences` in the `IStreamingReporter` base class,
and derived classes can modify it to express their own preferences.
Retrieving the preferences is now a non-virtual operation, which
makes it much cheaper to read them frequently. Previously, we
avoided doing so by caching the preferences in another variable,
but we still read them at least once per test case run.
