Build and Run: How to conveniently set the executable path?

[betonamu-jin]

I use CMake and Meson. Executables are placed in the build directory, organized according to the source directory structure. For example, for src/Foo/bar.m, the corresponding executable is build/src/Foo/bar.exe. I have dozens of single‑source programs like this.

A simple trick can be employed: take the full path to the source file (e.g., src/Foo/bar.m), transform it into build/src/Foo/bar.m, remove the file extension (.m in this case), and append .exe. This gives the working path: build/src/Foo/bar.exe.

But how can this be implemented on my end with the existing capabilities of Build and Run?

Not possible with the current current custom variables. Probably adding a ${relative_dir} (src/Foo/ in your example) would be enough because you could do:
build/${relative_dir}${current_doc_name}.exe. I'll add it later if useful.

Added ${relative_dir}.
