It's a bit silly and conveluted to have to call find_program on the
output of configure_file, so let's just allow passing files as the
script name.

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

Rust has it's own built in unit test format, which is invoked by
compiling a rust executable with the `--test` flag to rustc. The tests
are then run by simply invoking that binary. They output a custom test
format, which this patch adds parsing support for. This means that we
can report each subtest in the junit we generate correctly, which should
be helpful for orchestration systems like gitlab and jenkins which can
parse junit XML.

"more more" is one place where we don't need more.
Fixes #8097

Some license identifiers are ambiguous (e.g. "GPL3"). The SPDX license
identifiers avoid this by providing standardized and unique identifiers
(e.g. "GPL-3.0-only" or "GPL-3.0-or-later" for the previous example).
Because SPDX short-form identifiers are also both human- and
machine-readable we should recommend them in the documentation.
More information (advantages, details, etc.) can be found here:

Share common code to extract the `variables` kwarg in
declare_dependency() and pkg.generate().
|
|
Sometimes, distros want to configure a project so that it does not
use any bundled library. In this case, meson.build might want
to do something like this, where slirp is a combo option
with values auto/system/internal:
slirp = dependency('', required: false)
if get_option('slirp') != 'internal'
slirp = dependency('slirp',
required: get_option('slirp') == 'system')
endif
if not slirp.found()
slirp = subproject('libslirp', ...) .variable('...')
endif
and we cannot use "fallback" because the "system" value should never
look for a subproject.
This worked until 0.54.x, but in 0.55.x this breaks because of the
automatic subproject search. Note that the desired effect here is
backwards compared to the policy of doing an automatic search on
"required: true"; we only want to do the search if "required" is false!
It would be possible to look for the dependency with `required: false`
and issue the error manually, but it's ugly and it may produce an error
message that looks "different" from Meson's.
Instead, with this change it is possible to achieve this effect in an
even simpler way:
slirp = dependency('slirp',
required: get_option('slirp') != 'auto',
allow_fallback: get_option('slirp') == 'system' ? false : ['slirp', 'libslirp_dep'])
The patch also adds support for "allow_fallback: true", which is
simple and enables automatic fallback to a wrap even for non-required
dependencies.
|
|
Automatic fallback to subprojects is complicated and should be
pointed out outside the "fallback" keyword argument. It is also
surprising that fallback to a subproject will not happen if
override_dependency has already been used with the request
dependency. Document all this.
|
|
|
|
It was slightly wrong, and also make it a bullet point for easier
parsing.
|
|
The get_variable method is able to do everything they do and more,
making it generally more useful. Let's tell people to stop using the old
ones.

Deprecate meson.build_root() and meson.source_root()
|
|
Add a note about the portability of using shell constructs in the
custom_target() command.
|
|
|
|
Those function are common source of issue when used in a subproject because they
point to the parent project root which is rarely what is expected and is a
violation of subproject isolation.
|
|
|
|
This means that, in the common case of a simple meson.build which
doesn't contain any 'native: true' targets, we won't require a native
compiler when cross-compiling, without needing any changes in the
meson.build.

|
Documentation of most methods mentions method arguments enclosed in
parentheses. Two methods are an exception and we fix them here to make
the manual more consistent.
|
|
|
|
|
|
This method aims to offer a simple way to 'substring'
an existing string with start and end values.

This adds a new MESON_EXE_WRAPPER environment variable containing the
string form of the exe_wrapper, if there is an exe_wrapper defined.
Fixes #4427
|
|
The implementation of this function has changed enough that the name
doesn't really reflect what it actually does. It basically returns true
unless you're cross compiling, need and exe_wrapper, and don't have one.
The original function remains but is marked as deprecated.
This makes one small change the meson source language, which is that it
defines that can_run_host_binaries will return true in build == host
compilation, which was the behavior that already existed. Previously
this was undefined in build == host compilation.

Add support for Gtest as a test protocol
|
|
Gtest can output junit results with a command line switch. We can parse
this to get more detailed results than the returncode, and put those in
our own Junit output. We basically just throw away the top level
'testsuites' object, then fixup the names of the tests, and shove that
into our junit.

Allow meson.add_*_script to take additional types
|
|
|
|
|
|
- ExternalProgramHolder has path() method while CustomTargetHolder and
BuildTargetHolder have full_path().
- The returned ExternalProgramHolder's path() method was broken, because
build.Executable object has no get_path() method, it needs the
backend.
- find_program('overridden_prog', version : '>=1.0') was broken because
it needs to execute the exe that is not yet built. Now assume the
program has the (sub)project version.
- If the version check fails, interpreter uses
ExternalProgramHolder.get_name() for the error message but
build.Executable does not implement get_name() method.

Fix library(name_prefix: [])
|
|
When set to **true** only the last component is used. And throw in two minor
grammatical fixes while we're there.
|
|
Refine documentation of the default name_prefix, so people don't get the
impression they can write logic which uses 'lib' as the default, when
they should be defaulting to '[]', to let us take care of the
complexities.

Fixes #1949

Add add_languages(native:)
|
|
|
|
Now that subprojects can override the dependency name, there is no need
to provide a variable name for the fallback any more.
