A MesonException has file, lineno and colno attributes, which get
formatted as a location in mlog.exception().
The file attribute got changed from a path relative to the root source
directory to a pathname (absolute or relative to cwd) in one place in
commit b8fbbf59. Adjust all the other places the file attribute is set
to match.
Also:
Setting MesonException.file seems to be missing in the case where Parser
returned a non-CodeBlockNode object. Fortunately, that looks like it's
unreachable, but add it just in case.

This avoids the duplication where the option is stored in a dict at its
name, and also contains its own name. In general, the maxim in
programming is things shouldn't know their own name, so removed the name
field just leaving the option's position in the dictionary as its name.
|
|
Since we're adding arguments that use the cross_ prefix but are valid
we don't want to print "warning invalid argument name!", as that will
confuse people by virtue of being wrong.

This returns a list out of th keys of a dict. In both cases of use
remaining though it's used for checking membership, checking for list
membership, lists are O(n) lookup, while dicts are O(1), so removing
the abstraction reduces typing and improves performance.

Closes #3938.

We now pass the current subproject to every FeatureNew and
FeatureDeprecated call. This requires a bunch of rework to:
1. Ensure that we have access to the subproject in the list of
arguments when used as a decorator (see _get_callee_args).
2. Pass the subproject to .use() when it's called manually.
3. We also can't do feature checks for new features in
meson_options.txt because that's parsed before we know the
meson_version from project()

This is a special type of option to be passed to most 'required' keyword
arguments. It adds a 3rd state to the traditional boolean value to cause
those methods to always return not-found even if the dependency could be
found.
Since integrators doesn't want enabled features to be a surprise there
is a global option "auto_features" to enable or disable all
automatic features.

This simplifies a lot of code, and centralize "key=value" parsing in a
single place.
Unknown command line options becomes an hard error instead of
merely printing warning message. It has been warning it would become an
hard error for a while now. This has exceptions though, any
unknown option starting with "<lang>_" or "b_" are ignored because they
depend on which languages gets added and which compiler gets selected.
Also any option for unknown subproject are ignored because they depend
on which subproject actually gets built.
Also write more command line parsing tests. "19 bad command line
options" is removed because bad cmd line option became hard error and
it's covered with new tests in "30 command line".

It is important to keep the list of languages up to date in
optinterpreter, otherwise we could have conflicting options when adding
new languages.

Closes ##2853.

I have a tendency to typo things. Humans in general are bad at spotting
spelling mistakes, computers are not. This patches prints the bad
options and provides the generic meson "This will be a hard error
someday" message.

by leaving out the choices keyword.

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.
|
|
set_value() already does a better job at parsing strings, such as
accepting "True" for a boolean.
This fixes issue #2544
|
|
I've typo'd "value" for the last time, options needs a kwargs validator.
This validator is slightly different than the one used by the main
parser, since it operates on a much simpler representation than the
other one does, and they are not interchangeable.
This also changes the optinterpreter to use pop on 'type' and
'description' so that they're not passed to the validator as kwargs.
|

|
Instead, check that option keys don't contain ':'. Also change the
failing option test to look for this.

There are a few cases where a context manager cannot be used, such as
the logger.

That is, isinstance(x, y) or isinstance(x, z) can be flattened with a
tuple to isinstance(x, (y, z)).

This patch adds support for the D programming language[1] to Meson.
The following compilers are supported:

* GDC
* DMD
