Meson used to prepend '|' for each nested subproject to distinguish in
the logs where a subproject start and ends. It is more useful to print
the current subproject name.
Also print the call stack when starting a new subproject to better see
which subproject chain leads to to.
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.
get_non_matching_default_options is checking a string from
project_default_options against a validated value from
coredata.options.
Passing the string to validate_value ensures that the comparison
is sound; otherwise, "false" might be compared against False
and a bogus difference is printed.
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
- ModuleState is now a real class that will have methods in the future
for actions modules needs, instead of using interpreter internal API.
- New ModuleObject base class, similar to InterpreterObject, that should
be used by all objects returned by modules. Its methods gets the
ModuleState passed as first argument. It has a `methods` dictionary to
define what is public API that can be called from build definition.
- Method return value is not required to be a ModuleReturnValue any
more, it can be any type that interpreter can holderify, including
ModuleObject.
- Legacy module API is maintained until we port all modules.
In the future modules should be updated:
- Use methods dict.
- Remove snippets.
- Custom objects returned by modules should all be subclass of
ModuleObject to get the state iface in their methods.
- Modules should never call into interpreter directly and instead state
object should have wrapper API.
- Stop using ModuleReturnValue in methods that just return simple
objects like strings. Possibly remove ModuleReturnValue completely
since all objects that needs to be processed by interpreter (e.g.
CustomTarget) should be created through ModuleState API.
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')`
The way the tracking is currently done it works if no new subprojects
are added to a configured build directory. For cases where we want to
add a new subproject, it fails because we don't initialize builtins for
that subproject. This corrects that by checking to see if the subproject
already exists, and if it doesn't initializes the bultins for it.
Fixes: #8421
Useful in case of boolean values to distinguish between a boolean
value having been set in the native/cross file and not having been
provided, which can't be achieved by passing a fallback parameter
to .get_external_property().
It's a pure subset of `get_external_property`, and has odd behavior in
host == build configurations. `get_external_property` is clear, and uses
the standard `native : bool` syntax to control host vs build properties
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.
This is a) useless because it's only used to print which options are not
default, and b) harmful because it can result in cases where things
break, like in projects that set a standard that the chosen compiler
doesn't support, but the project (or some subset) can be built with a
different standard.
Fixes: #8360
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.
Following #7890, this patch introduces the ability to read the contents
of a file to the fs module.
This patch introduces the ability to read files at configure time, but
has some restrictions:
- binary files are not supported (I don't think this will prove a
problem, and if people are wanting to do something with binary
files, they should probably be shelling out to their own script).
- Only files outside the build directory allowed. This limitation
should prevent build loops.
Given that reading an arbitrary file at configure time can affect the
configuration in almost arbitrary ways, meson should force a reconfigure
when the given file changes. This is non-configurable, but this can
easily be changed with a future keyword argument.
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`.
It is common, at least in GNOME projects, to have scripts that must be
run only in the final destination, to update system icon cache, etc.
Skipping them from Meson ensures we can properly log that they have not
been run instead of relying on such scripts to to it (they don't
always).
On Windows this would fail because of missing DLL:
```
mylib = library(...)
exe = executable(..., link_with: mylib)
meson.add_install_script(exe)
```
The reason is on Windows we cannot rely on rpath to find libraries from
build directory, they are searched in $PATH. We already have all that
mechanism in place for custom_target() using ExecutableSerialisation
class, so reuse it for install/dist/postconf scripts too.
This has bonus side effect to also use exe_wrapper for those scripts.
