The StringMaker is off by default and can be enabled by a new macro `CATCH_CONFIG_ENABLE_VARIANT_STRINGMAKER`, to avoid increasing the footprint of stringification machinery by default.
The desired behaviour was to match a literal "[.]", so the regex
has to be escaped as "\\[\\.\\]" -- double backslashes, because
it has to be escaped from CMake as well as from the regex engine.
This means
* Adding new configuration toggle `CATCH_CONFIG_DISABLE_EXCEPTIONS`
and a best-guess configuration auto-checking for it.
* Adding new set of internal macros, `CATCH_TRY`, `CATCH_CATCH_ALL`
and `CATCH_CATCH_ANON` that can be used in place of regular `try`,
`catch(...)` and `catch(T const&)` respectively, while disappearing
when `CATCH_CONFIG_DISABLE_EXCEPTIONS` is enabled.
* Replacing all uses of `throw` with calls to `Catch::throw_exception`
customization point.
* Providing a default implementation for the above customization point
when `CATCH_CONFIG_DISABLE_EXCEPTIONS` is set.
* Letting users override this implementation with their own.
* Some minor changes and ifdefs all around to support the above
issue #1360
It is possible to have multple given contexts in a single BDD scenario;
if you have to type 'and' in the GIVEN description; it's very likely you
need an AND.
A generic AND is not possible, thus a AND_GIVEN is added to complement
the AND_WHEN and AND_THEN.
Can be used without needing to increase indent:
SCENARIO("...") {
GIVEN("...")
AND_GIVEN("...") {
WHEN("...") {
THEN("...") {
// ...
}
}
}
}
would correctly output, when requested/needed:
Given: ...
And given: ...
When: ...
Then: ...
The padding had to be increased by a character in the output message, to
continue to be uniform.
This is because otherwise the installations paths provided via
GNUInstallDirs become messed up and parts of the installation
package will end up in the wrong place.
Also it doesn't make much sense to force dependees to also install
our header alongside them.
Closes#1373
Because of a change in VS toolset, missing option <UseFullPaths>
is no longer interpreted as "don't pass /FC to the compiler", but
rather as "pass /FC to the compiler". This is problematic, because
/FC not only changes how much of the path is reporter by the compiler
(e.g. in `__FILE__` macro), but it also lower cases the path.
This lower-casing of the path broke our approval tests for VS2017
about 5 months ago.
Using CMake 3.13 (not yet released) would also let us fix it, but
for now we use a vcxproj.user file that is merged with the main project
and explicitly disables `/FC`.
This means
* a new cmake option, `CATCH_BUILD_EXTRA_TESTS`, that conditionally
includes the ExtraTests subfolder
* building and running them on some of the Travis build images
* An example configuration test
In the future these should be extended to cover most of the
configuration options in Catch2, but this is a start.
The support is to be considered experimental, that is, the interfaces,
the first party generators and helper functions can change or be removed
at any point in time.
Related to #850
In case of 2 instances of SourceLineInfo constructed in the same
file, they will have the same `file` pointer (even at O0). Thus, we
can check if they are equal before calling potentially pointless
`strcmp`.
In theory the copy is cheap (couple of pointers change), but tests
are usually compiled in Debug mode/with minimal optimizations, which
means that most users will still have to pay the cost for those
function calls.
