"Stored by value" is more correct way to explain that example.
Mutable vs immutable means that you cannot mutate the value (e.g. list vs tuple in Python), and the example shows that `var2` is actually mutable.
Copying/storing a reference vs value is what what matters in the assignment, in Python `a=b` means `a` and `b` are references to the same list, while in meson `a=b` copies the value of `b` into `a`.
This will help facilitate cache busting in certain situations, and
replaces hand-rolled solutions of writing a length command to remove
various files/folders within the subprojects directory.
When using --reset we should guarantee that next reconfigure will pick
the latest code. For wrap-file we have no way to know if the revision
changed, so we have to delete the source tree and extract again.
It is unlikely that user has local changes in non-git subprojects, and
--reset is known to be dangerous.
Replace `meson compile scan-build` with `ninja -C dir scan-build`,
because scan-build target does not work with `meson compile`.
Note about SCANBUILD env variable was not precise enough to describe how
to pass arguments to scan-build - provide an example to make it clear.
Fixes: #7644.
Currently the Qt Dependencies still use the old "combined" method for
dependencies with multiple ways to be found. This is problematic as it
means that `get_variable()` and friends don't work, as the dependency
can't implement any of those methods. The correct solution is to make
use of multiple Dependency instances, and a factory to tie them
together. This does that.
To handle QMake, I've leveraged the existing config-tool mechanism,
which allows us to save a good deal of code, and use well tested code
instead of rolling more of our own code.
The one thing this doesn't do, but we probably should, is expose the
macOS ExtraFrameworks directly, instead of forcing them to be found
through QMake. That is a problem for another series, and someone who
cares more about macOS than I do.
In commit caab4d3d, the uid and gid arguments passed to os.chown() by
set_chown() were accidentally swapped, causing files to end up with
incorrect owner/group if the owner and group are not the same.
Also update the documentation to better indicate which argument to
install_mode is which.
