Clang has a hand `-Wunused-command-line-argument` switch, which when
turned to an error, gets very grump about `-flto-jobs=0` being set in
the compiler arguments (although `-flto=` belongs there). We'll refactor
a bit to put that only in the link arguments.
GCC doesn't have this probably because, a) it doesn't have an equivalent
warning, and b) it uses `-flto=<$numthreads.
Fixes: #8347
run_target() does some variable substitutions since 0.57.0. This is a
new behavior, and undocumented, caused by sharing more code with
custom_target(). More consistency is better, so document it now.
custom_target() was doing variable substitution in the past, because it
shared some code with generator(), but that was undocumented. Some
refactoring in 0.57.0 caused it to not replace @CURRENT_SOURCE_DIR@,
@SOURCE_DIR@, and @BUILD_DIR@ anymore. This patch adds back
@CURRENT_SOURCE_DIR@ and document it. It does not add back @SOURCE_DIR@
because it is duplicate with @SOURCE_ROOT@ that has a better name. Also
do not add back @BUILD_DIR@ which is duplicate of @PRIVATE_DIR@, and
not @BUILD_ROOT@ surprisingly, adding to the confusion.
Or other language flags that use CPPFLAGS (like CXXFLAGS). The problem
here is actually rather simple, `dict.setdefault()` doesn't work like I
thought it did, I thought it created a weak entry, but it actually is
equivalent to:
```python
if k not in dict:
dict[k] = v
```
Instead we'll use an intermediate dictionary (a default dictionary
actually, since that makes things a little cleaner) and then add the
keys from that dict to self.options as applicable.

Fix "meson test --wrapper foo --setup bar", it should work just fine
if the setup does not define a wrapper.

install_subdir() with a non-existing subdir creates the directory in the
target directory. This seems like an implementation detail but is quite useful
to create new directories for e.g. configuration or plugins in the installed
locations.
git bisect says this started with 8fe8161014.
Let's add a test for it and document it to make this behavior official.
Limitation: it can only create at the install_dir location, trying to create
nested subdirectories does not work and indeed creates the wrong directory
structure. That is a bug that should be fixed separately:
install_subdir('blah',
install_dir: get_option('prefix'))
install_subdir('sub/foobar',
install_dir: get_option('prefix'))
install_subdir('foo/baz',
install_dir: get_option('prefix'))
$ tree ../_inst
../_inst
├── baz
├── blah
└── foobar
Fixes#2904
This allows representing functions like assert(), which take optional
positional arguments, which are not variadic. More importnatly you can
represent a function like (* means optional, but possitional):
```txt
func(str, *int, *str)
```
typed_pos_args will check that all of your types are correct, and if not
provide None, which allow simplifying a number of implementation details
We don't do a very good job of type checking in the interpreter,
sometimes we leave it to the mid layers of backends to do that (layering
violations) and sometimes we just don't check them at all. When we do
check them it's a ton of boilerplate and complicates the code. This
should help quite a bit.
Re-implement it in backend using the same code path as for
custom_target(). This for example handle setting PATH on Windows when
command is an executable.
Both Clang and GCC support using multiple threads for preforming link
time optimizaions, and they can now be configured using the
`-Db_lto_threads` option.
Fixes#7820
This new keyword argument makes it possible to run specific
test setups only on a subset of the tests. For example, to
mark some tests as slow and avoid running them by default:
add_test_setup('quick', exclude_suites: ['slow'], is_default: true)
add_test_setup('slow')
It will then be possible to run the slow tests with either
`meson test --setup slow` or `meson test --suite slow`.
[why]
In test case 10 the project is installed twice. This has been introduced
with commit
55abe16 unit tests: Test that relative install_rpath works correctly
where the cxx tests where added by copy and paste.
[how]
First test all build rpaths, then after install all install rpaths.
[note]
The aforementioned commit is a bit strange in that it adds a tests with
a relative rpath with cxx files but not with c files.

[why]
If we build and test a library we need to make sure that we find the
currently build library object first, before an older system installed
one.
This can be broken if the library in question is installed in a custom
path, and another library we depend on also is installed there.
[how]
Just move the rpath to the current build artifacts to the front.
Solves #8030.

aligning along the left is, I think, what most projects want to do.
Aligning along the middle looks subjectively ugly, and objectively
prevents me from further indenting an element, e.g.
Build information:
prefix : /usr
sysconfdir : /etc
conf file : /etc/myprogram.conf
This both moves the env reading to configuration time, which is useful,
and also simplifies the implementation of the boost dependency. The
simplification comes from being able to delete basically duplicated code
since the values will be in the Properties if they exist at all.
This is PEP8 convention for a const variable. Also, make the type
Mapping, which doesn't have mutation methods. This means mypy will warn
us if someone tries to change this.
* doc: fix hotdoc misuse for dynamically generated content
hotdoc has a native include feature for including files inline. Use this
to generate one file for each dynamically generated code block, and
include that file in Commands.md; see:
https://hotdoc.github.io/syntax-extensions.html#smart-file-inclusion-syntax
This permits us to move back to using the in-tree version of the hotdoc
*.md sources, thus fixing the incorrect inclusion of "builddir/" in the
"Edit on github" links which resulted from using copies as the source.
Fixes#8061
* doc: call the dummy file a "stamp" as it is a better known term
It is cleaner than collections.namedtuple. It also catches that "count()" is
a method on tuple, so rename the field to num_tests.

Pass the StringIO object to the parse method instead, because

This patches takes the options work to it's logical conclusion: A single
flat dictionary of OptionKey: UserOptions. This allows us to simplify a
large number of cases, as we don't need to check if an option is in this
dict or that one (or any of 5 or 6, actually).
I would have prefered to do these seperatately, but they are combined in
some cases, so it was much easier to convert them together.
this eliminates the builtins_per_machine dict, as it's duplicated with
the OptionKey's machine parameter.
