There is no easy way to specify additional parameter (include directory) to the linter

[zhou13]

In a C++ project, it is common that we need to specify the include directory using-Iinclude. Currently, there is no easy way to do this unless we ignore the default maker and write our own. Even by doing this, it is hard to achieve per-project control of the include directory.

Plugins such as YCM and deoplete-clang provides per-project configuration file such as .ycm_extra_conf.py and .clang. It can be much more convenient if neomake has the similar feature.

something like

autocmd BufRead ~/projects/myproject/*
    \   let b:includes = '~/projects/myproject/includes'
    \ | let b:neomake_cpp_mylinter_args = [ '-Iinclude' . b:include_directory ]

might be what you're looking for. Maybe look into project specific/relative vimrc files, in conjunction.

I've actually done something similar in which I run the phpcs linter with special args just for WordPress projects (non-wordpress projects will use the default phpcs args):

I don't like idea to hard code any path in my vimrc. I actually solved it using something similar using lvimrc. However I still hope this should be natively supported.

Check out https://github.com/embear/vim-localvimrc, which allows for a .lvimrc file for your project.

But I agree that we should be able to pass in arguments to makers.
I am going to close it as duplicate of #589 for now. There are references to other issues in there.
