This exposes the already existing UserStringArrayOption class through
the meson_options.txt. The intention is to provide a way for projects to
take list/array type arguments and validate that all of the elements in
that array are valid without using complex looping constructrs.
While finding an external program, we should only split the shebang
once since that is what Linux and BSD also do. This is also why
everyone uses #!/usr/bin/env in their shebangs since that allows
you to run an interpreter in a path with spaces in it.
See `man execve` for more details, specifically the sections for
interpreter scripts.
Although some other base types like boolean objects can be expresed
as strings, this is not possible with int objects.
This patch adds support to express int values as strings as hex,
decimal or octal values.
Currently, run_target does not get namespaced for each subproject,
unlike executable and others. This means that two subprojects sharing
the same run_target name cause meson to crash.
Fix this by moving the subproject namespacing logic from the BuildTarget
class to the Target class.
subproject using wrap-file is broken since commit (68bd64c Prevent
projects from directly grabbing files from other subprojects. )
subproject with wrap-file usually have version number after name
- **sproj_name** is `zlib-1.2.8` according to `directory = zlib-1.2.8`
of zlib.wrap
- but **self.subproject** `zlib`
This allows a CustomTarget to be indexed, and the resulting indexed
value (a CustomTargetIndex type), to be used as a source in other
targets. This will confer a dependency on the original target, but only
inserts the source file returning by index the original target's
outputs. This can allow a CustomTarget that creates both a header and a
code file to have it's outputs split, for example.
Fixes#1470
Currently sources, generated sources, or objects are considered to be
sources for a target, but link_whole should also fulfill the sources
requirement.
Fixes#2180
Currently meson only considers what compiler/linker were used by a
Target's immediate sources or objects, not the sources of libraries it's
linked with by the link_with and link_while keywords. This means that if
given 3 libraries: libA which is C++, libB which is C, and libC which is
also C, and libC links with libB which links with libA then linking libC
will be attempted with the C linker, and will fail.
This patch corrects that by adding the compilers used by sub libraries
to the collection of compilers considered by meson when picking a
linker.
This adds a new process_compilers_late method to the BuildTarget class,
which is evaluated after process_kwargs is called. This is needed
because some D options need to be evaluated after compilers are
selected, while for C-like languages we need to check the link* targets
for language requirements, and link* targets are passed by kwargs.
This implementation is recursive, since each Target adds it's parent's
dependencies.
