Create gem bundle for cmock

[SteinHeselmans]

For projects not using ceedling, it would be convenient to be able to install a version of cmock using gem installer. Currently those projects need to submodule cmock.git, which leads to many downloads on uncached CI jobs.

There is probably a few pitfalls as cmock doesn't only deliver a ruby package, but also some c and h files. Those need to be part of the package as well, and some convenience will be needed in order to add them to the compiler/linker.

@mvandervoord do you see this as a feasible idea or are the pitfalls hard to avoid?

[mvandervoord]

This is definitely doable. It requires a small script to be added which would allow the gem to support the C files in either of the two ways that Ceedling handles them.

• "install" cmock to your project (copy the c and header files).
• provide a central place where the build system could ask where those files are.

So for Ceedling it could handle them in both ways? Do you have some preference of which would be a better way (seems like first is easier to implement on first glance)?

[mvandervoord]

Ha. I think about this one with each release, but have never jumped in and done it. I still love this idea. I thing it should be a ruby gem, and I think the user should be able to call something like cmock install <path> and it should copy the C source and header files to that path. Then, cmock should be callable from the command line as usual.

May we contact ceedling packagers to see if cmock could be split out ?

Hahaha. @mvandervoord is maintainer of whole ecosystem, so we can rather buy him a coffee, or learn from his Ceedling GitHub Actions (ThrowTheSwitch/Ceedling#739) how to package Ruby, and then just copy it here and try to reproduce it.

I just hope he will not add too much non-related stuff in that pull request, so that I will be able to decipher it 😜
