There's no reason to allow None into the backend, it already has code to
check that all of the values of the FileMode object are None, so let's
use that, which is much simpler all the way down.
As seen in the testcase, passing objects to custom_target does not work
if headers are passed extract_objects(), or if extract_all_objects() is used
and the sources include any header files. To fix this, use the code that
already exists for unity build to filter out the nonexistent ".h.o" files.
This already gives for free the handling of genlist, which was mentioned
in a TODO comment.
For qt we already have all of the necissary checking in place. Now in
the interpreter we have the same, the intrperter does all of the
checking, then passed the arguments to the Generator initializer, which
just assigns the passed values. This is nice, neat, and clean and fixes
the layering violatino between build and interpreter.
When mutable items are stored in an lru cache, changing the returned
items changes the cached items as well. Therefore we want to ensure that
we're not mutating them. Using the ImmutableListProtocol allows mypy to
find mutations and reject them. This doesn't solve the problem of
mutable values inside the values, so you could have to do things like:
```python
ImmutableListProtocol[ImmutableListProtocol[str]]
```
or equally hacky. It can also be used for input types and acts a bit
like C's const:
```python
def foo(arg: ImmutableListProtocol[str]) -> T.List[str]:
arg[1] = 'foo' # works while running, but mypy errors
```
The build level shouldn't be deal with interpreter objects, by the time
they leave the intpreter they should be in the Meson middle layer
representaiton
Dependencies is already a large and complicated package without adding
programs to the list. This also allows us to untangle a bit of spaghetti
that we have.
All changes were created by running
"pyupgrade --py3-only --keep-percent-format"
and committing the results. I have not touched string formatting for
now.
- use set literals
- simplify .format() parameter naming
- remove __future__
- remove default "r" mode for open()
- use OSError rather than compatibility aliases
- remove stray parentheses in function(generator) scopes
Rather than having to manually build the locale aware man paths with
`install_data('foo.fr.1', install_dir: join_paths(get_option('mandir'), 'fr', 'man1'), rename: 'foo.1')`
Support doing
`install_man('foo.fr.1', locale: 'fr')`
By default all subprojects are installed. If --skip-subprojects is given
with no value only the main project is installed. If --skip-subprojects
is given with a value, it should be a coma separated list of subprojects
to skip and all others will be installed.
Fixes: #2550.
