This includes always compiling the ANSI and None colour
implementations, as they don't need to touch any platform
specific APIs, and removing their respective compile-time
configuration options.
Because the Win32 colour implementation requires Win32-specific
APIs, it is still hidden behind a compile-time toggle,
`CATCH_CONFIG_COLOUR_WIN32` (renamed from `..._COLOUR_WINDOWS`).
The commandline options for colours were also changed. The
option now uses different name, and allows to select between
different implementations, rather than changing whether
the compiled-in colour implementation is used through
"yes/no/default" options.
Forcing it to be engaged explicitly, either via `op<<`, or by
`ColourGuard::engage`, fixes an issue with multiple `ColourGuard`s
being constructed in a single expression. Because the construction
of the `ColourGuard` instances can happen in arbitrary order,
colours would be applied in arbitrary order too. However, a chain
of `op<<`s has strict call orders, fixing this issue.
This opens path to per-reporter colour output customization,
and fixes multiple issues with the old colour implementation.
Under the old implementation, using Win32-backed colouring
would always change the colour used by the console, even if the
actual output was written elsewhere, such as a file passed by
the `--out` flag. This will no longer happen, as the reporter's
colour impl will check that the reporter's stream is pointed
to console before trying to change the colours.
POSIX/ANSI colour implementation suffered a similar-ish issue,
in that it only wrote the colour escape codes into the default
output stream, even if the reporter asking for colouring was
actually writing to a completely different output stream.
Previous splitting of catch_common.hpp left it containing only one
actual thing, which is the `SourceLineInfo` type. Given that, there
is no reason to keep the old name.
Also found out that it was included in some places for no reason
(primarily Matchers).
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.
This is both a really big and a really small commit. It is small in
that it only contains renaming, moving and modification of include
directives caused by this.
It is really big in the obvious way of touching something like 200
files.
The new rules for naming files is simple: headers use the `.hpp`
extension. The rules for physical file layout is still kinda in
progress, but the basics are also simple:
* Significant parts of functionality get their own subfolder
* Benchmarking is in `catch2/benchmark`
* Matchers are in `catch2/matchers`
* Generators are in `catch2/generators`
* Reporters are in `catch2/reporters`
* Baseline testing facilities are in `catch2/`
* Various top level folders also contain `internal` subfolder,
with files that users probably do not want to include directly,
at least not until they have to write something like their own
reporter.
* The exact files in these subfolders is likely to change later
on
Note that while some includes were cleaned up in this commit, it
is only the low hanging fruit and further cleanup using automatic
tooling will happen later.
Also note that various include guards, copyright notices and file
headers will also be standardized later, rather than in this commit.
