## New method to preprocess source files
|
||
|
|
|
||
|
|
Compiler object has a new `preprocess()` method. It is supported by all C/C++
|
||
|
|
compilers. It preprocess sources without compiling them.
|
||
|
|
|
||
|
|
The preprocessor will receive the same arguments (include directories, defines,
|
||
|
|
etc) as with normal compilation. That includes for example args added with
|
||
|
|
`add_project_arguments()`, or on the command line with `-Dc_args=-DFOO`.
|
||
|
|
|
||
|
|
```meson
|
||
|
|
cc = meson.get_compiler('c')
|
||
|
|
pp_files = cc.preprocess('foo.c', 'bar.c', output: '@PLAINNAME@')
|
||
|
|
exe = executable('app', pp_files)
|
||
|
|
```
