Allow macro_name to be speficied as a parameter to configure_file().
This allows C macro-style include guards to be added to
configure_file()'s output when a template file is not given. This change
simplifies the creation of configure files that define macros with
dynamic names and want the C-style include guards.
- On Windows, it was not detected if include directory was an absolute
path to source directory, because of the mis of path separators.
- In the edgecase the include directory begins with the exact same
string as the source directory, but is a different directory, it was
falsely reported as an error.
Fixes#12217.
Update builtin function list using the refman
python docs/genrefman.py \
-g vim \
-o data/syntax-highlighting/vim/syntax/
This also drops gettext() and find_library() from the list of builtin
functions that have been deprecated since 2016.
Changes are squashed here because test_vim_syntax_highlighting() would
validate the file against the list of builtin functions that no longer
matches the yaml documentation.

This has no actual effect on the codebase as type checkers (still)
support both and negligible effect on runtime performance since
__future__ annotations ameliorates that. Technically, the bytecode would
be bigger for non function-local annotations, of which we have many
either way.
So if it doesn't really matter, why do a large-scale refactor? Simple:
because people keep wanting to, but it's getting nickle-and-dimed. If
we're going to do this we might as well do it consistently in one shot,
using tooling that guarantees repeatability and correctness.
Repeat with:
```

This fixes two issues in constructing the default installation path
when install_dir is not specified:
- inside a subproject, install_data() would construct the destination
path using the parent project name instead than the current project
name,
- when specifying preserve_path, install_data() would construct the
destination path omitting the project name.
Fixes#11910.
The function name adheres to the pattern used by many other Meson DSL
implementation methods, thus stating that this is the implementation
of the functionality without argument validation is not very useful.
The docstring is separated from the function declaration by a blank
line. Removing the docstring avoids having to decide if the blank line
should be there or not.
Since it's deprecated anyway, we don't really want to plumb it all the
way down into the build and backend layers. Instead, we can just turn
it into a `win_subsystem` value in the interpreter if `win_subsystem`
isn't already set.
We know exactly what type we need, since the interpreter function is
correctly typed and thinly wraps over this. But we didn't even get the
container type correct. :(
This moves to a list of shared objects inside the type_checking module.
This is based on my experience of fully typing all of these functions
several times, and will make it easier to slowly land all of the changes
we want to make.
This detects cases where module A imports a function from B, and C
imports that same function from A instead of B. It's not part of the API
contract of A, and causes innocent refactoring to break things.
* Capture all compile args from the first round of ninja backend generation for all languages used in building the targets so that these args, defines, and include paths can be applied to the .vcxproj's intellisense fields for all buildtypes/configurations.
Solution generation is now set up for mutiple build configurations (buildtypes) when using '--genvslite'.
All generated vcxprojs invoke the same high-level meson compile to build all targets; there's no selective target building (could add this later). Related to this, we skip pointlessly generating vcxprojs for targets that aren't buildable (BuildTarget-derived), which aren't of interest to the user anyway.
When using --genvslite, no longer inject '<ProjectReference ...>' dependencies on which a generated .vcxproj depends because that imposes a forced visual studio build dependency, which we don't want, since we're essentially bypassing VS's build in favour of running 'meson compile ...'.
When populating the vcxproj's shared intellisense defines, include paths, and compiler options fields, we choose the most frequent src file language, since this means more project src files can simply reference the project shared fields and fewer files of non-primary language types need to populate their full set of intellisense fields. This makes for smaller .vcxproj files.
Paths for generated source/header/etc files, left alone, would be added to solution projects relative to the '..._vs' build directory, where they're never generated; they're generated under the respective '..._[debug/opt/release]' ninja build directories that correspond to the solution build configuration. Although VS doesn't allow conditional src/header listings in vcxprojs (at least not in a simple way that I'm aware of), we can ensure these generated sources get adjusted to at least reference locations under one of the concrete build directories (I've chosen '..._debug') under which they will be generated.
Testing with --genvslite has revealed that, in some cases, the presence of 'c:\windows\system32;c:\windows' on the 'Path' environment variable (via the make-style project's ExecutablePath element) is critical to getting the 'meson compile ...' build to succeed. Not sure whether this is some 'find and guess' implicit defaults behaviour within meson or within the MSVC compiler that some projects may rely on. Feels weird but not sure of a better solution than forcibly adding these to the Path environment variable (the Executable Path property of the project).
Added a new windows-only test to windowstests.py ('test_genvslite') to exercise the --genvslite option along with checking that the 'msbuild' command invokes the 'meson compile ...' of the build-type-appropriate-suffixed temporary build dir and checks expected program output.
Check and report error if user specifies a non-ninja backend with a 'genvslite' setup, since that conflicts with the stated behaviour of genvslite. Also added this test case to 'WindowsTests.test_genvslite'
I had problems tracking down some problematic environment variable behaviour, which appears to need a work-around. See further notes on VSINSTALLDIR, in windowstests.py, test_genvslite.
'meson setup --help' clearly states that positional arguments are ... [builddir] [sourcedir]. However, BasePlatformTests.init(...) was passing these in the order [sourcedir] [builddir]. This was producing failures, saying, "ERROR: Neither directory contains a build file meson.build." but when using the correct ordering, setup now succeeds.
Changed regen, run_tests, and run_install utility projects to be simpler makefile projects instead, with commands to invoke the appropriate '...meson.py --internal regencheck ...' (or install/test) on the '[builddir]_[buildtype]' as appropriate for the curent VS configuration. Also, since the 'regen.vcxproj' utility didn't work correctly with '--genvslite' setup build dirs, and getting it to fully work would require more non-trivial intrusion into new parts of meson (i.e. '--internal regencheck', '--internal regenerate', and perhaps also 'setup --reconfigure'), for now, the REGEN project is replaced with a simpler, lighter-weight RECONFIGURE utility proj, which is unlinked from any solution build dependencies and which simply runs 'meson setup --reconfigure [builddir]_[buildtype] [srcdir]' on each of the ninja-backend build dirs for each buildtype.
Yes, although this will enable the building/compiling to be correctly configured, it can leave the solution/vcxprojs stale and out-of-date, it's simple for the user to 'meson setup --genvslite ...' to fully regenerate an updated, correct solution again. However, I've noted this down as a 'fixme' to consider implementing the full regen behaviour for the genvslite case.
* Review feedback changes -
- Avoid use of 'captured_compile_args_per_buildtype_and_target' as an 'out' param.
- Factored a little msetup.py, 'run(...)' macro/looping setup steps, for genvslite, out into a 'run_genvslite_setup' func.
* Review feedback: Fixed missing spaces between multi-line strings.
* 'backend_name' assignment gets immediately overwritten in 'genvslite' case so moved it into else/non-genvslite block.
* Had to bump up 'test cases/unit/113 genvslites/...' up to 114; it collided with a newly added test dir again.
* Changed validation of 'capture' and 'captured_compile_args_...' to use MesonBugException instead of MesonException.
* Changed some function param and closing brace indentation.
We don't need a CMakeInterpreter until and unless we actually attempt to
use a cmake subproject via the cmake module.
Minus 10 files and 3679 lines of code imported at startup.
This is useful for totally terrible stuff that we really dislike, but
for some reason we are afraid to just use `mlog.deprecation()` and
unconditionally tell people so.
Apparently this is because it is totally absolutely vital that, when
telling people something is so broken they should never ever ever use it
no matter what, ever... we can't actually tell them that unless they
bump the minimum version of Meson, because that's our standard way of
introducing a **version number** to tell them when we first started
warning about this.
Sigh. We really want to warn people if they are doing totally broken
stuff no matter what version of Meson they support, because it's not
like fixing the thing that never worked is going to suddenly break old
versions of meson.
So. Here's some new functionality that always warns you, but also tells
you when we started warning.
When a project targets a dev version of Meson (e.g. 1.1.99) for
experimenting, this allows to use:
project(..., meson_version: '>=1.2.0')
It avoids getting warnings when using FeatureNew for features introduced
in 1.2.0.
This is a pretty common pattern in python (the standard library uses it
a ton): A class is created, with a single private instance in the
module, and then it's methods are exposed as public API. This removes
the need for the global statement, and is generally a little easier to
reason about thanks to encapsulation.
To take good decisions we'll need to know if we are a Rust library which
is only know after processing source files and compilers.
Note that is it not the final list of compilers, some can be added in
process_compilers_late(), but those are compilers for which we don't
have source files any way.
This allows changing the crate name with which a library ends up being
available inside the Rust code, similar to cargo's dependency renaming
feature or `extern crate foo as bar` inside Rust code.
We need to remember its value when reconfiguring, but the Build object
is not reused, only coredata is.
This also makes CLI more consistent by allowing `-Dvsenv=true` syntax.
Fixes: #11309
We will still try to load `meson_options.txt` if `meson.options` doesn't
exist. Because there are some advantages to using `meson.options` even
with older versions of meson (such as better text editor handling)
we will not warn about the existence of a `meson.options` file if a
`meson_options.txt` file or symlink also exists.
The name `meson.options` was picked instead of alternative proposals,
such as `meson_options.build` for a couple of reasons:
1. meson.options is shorter
2. While the syntax is the same, only the `option()` function may be
called in meson.options, while, it may not be called in meson.build
3. While the two files share a syntax and elementary types (strings,
arrays, etc), they have different purposes: `meson.build` declares
build targets, `meson.options` declares options. This is similar to
the difference between C's `.c` and `.h` extensions.
As an implementation detail `Interpreter.option_file` has been removed,
as it is used exactly once, in the `project()` call to read the options,
and we can just calculate it there and not store it.
Fixes: #11176
It can only be used for projects that don't have any rules at all, i.e.
they are purely using Meson to:
- configure files
- run (script?) tests
- install files that exist by the end of the setup stage
This can be useful e.g. for Meson itself, a pure python project.
