Currently we manually pass the argparse action, this isn't very DRY,
since the builtin_types already has all the data necessary to find that.
This adds a new function to determine the action based on the default
type.
Implementing set_value() in the base class simplifies the code and
ensure validation is always consistent.
This fix UserIntegerOption.validate_value() not checking min/max value,
and UserArrayOption.validate_value() raising exception because it does
not pass a value for user_input argument of validate() method.
There's no reason not to also look in these places on Cygwin or OSX. Don't
do this on Windows, as these paths aren't meaningful there.
Move test_cross_file_system_paths from LinuxlikeTests to AllPlatformTests.
Duplicated options in array types have been removed by a previous
commit but someone could be using it.
The previous behaviour has been restored but the existence of
duplicates is now tested, and in that case a `DEPRECATION` message
is shown.
Array options can receive duplicated values, which can produce
errors if case those duplicated values make processing some
elements twice when they are expected to be processed only once.
One thing that makes cross compiling with meson a pain is the need for
cross files. The problem is not with cross files themselves (they're
actually rather brilliant in that they allow for a much greater deal of
flexibility than autotools hardcoded paths approach) but that each user
needs to reimplement them themselves, when for most people what they
really want is a cross file that could be provided by their distro, all
they really want is the correct toolchain.
This patch is the first stop to making it easier for distros to ship
their own cross files (and for users to put their's somewhere safe so
they don't get `git clean`ed. It allows the cross files (on Linux and
*BSD) to be stored in home and system paths (~/.config/meson/cross,
/usr/share/meson/cross, and /usr/local/share/meson/cross), and to be
loaded by simply by specificying --cross-file.
With this patch meson will check the locations its always checked first,
(is cross file absolute, or is it relative to $PWD), then will check
~/.config/meson/cross, /usr/local/share/meson/cross,
/usr/share/meson/cross, (or $XDG_CONFIG_PATH and $XDG_DATA_DIRS) for the
files, raising an exception if it cannot find the specified cross file.
Fixes#2283
This exposes the already existing UserStringArrayOption class through
the meson_options.txt. The intention is to provide a way for projects to
take list/array type arguments and validate that all of the elements in
that array are valid without using complex looping constructrs.
Rather than requiring a bit of boilerplate in every meson.build, which is
only documented in a comment in mesoncore.py, use sensible defaults for
sysconfdir, localstatedir and sharedstatedir depending on the prefix.
Fixes#1637
v2:
For clarity, give get_builtin_option_default() a noneIfSuppress argument,
rather than overloading prefix '' and None with special meanings.
The old caching was a mess of spaghetti code layered over pasta code.
The new code is well-commented, is clear about what it's trying to do,
and uses a blacklist of keyword arguments instead of a whitelist while
generating identifiers for dep caching which makes it much more robust
for future changes.
The only side-effect of forgetting about a new keyword argument would
be that the dependency would not be cached unless the values of that
keyword arguments were the same in the cached and new dependency.
There are also more tests which identify scenarios that were broken
earlier.
