Languageclient-neovim: How to set InitializeParams.initializationOptions?

[htfy96]

I am trying to get this client working with CQuery, a new C++ language server. However, it reported that FATL| Initialization parameters (particularily cacheDirectory) are required in its log because during initialize, initializationOptions.cacheDirectory must be set.

It seems that currently there is no way to set these options in this plugin. This problem also affects clangd, which by default works only in C++98 mode and considers all syntax in C++11 as errors. Is it possible to set initializationOptions with default values/callback functions?

Thanks.

I added a little wiki page to help to settup cquery with LanguageClient-neovim https://github.com/autozimu/LanguageClient-neovim/wiki/cquery

It's better to have some way to use different initializationOptions for different language servers

{
        "initializationOptions": {
                "cacheDirectory": "/tmp/cquery",
        "resourceDirectory": "yourCQueryDirectory/clang_resource_dir"
        }
}

That's right, I just asked about this here: https://github.com/autozimu/LanguageClient-neovim/issues/633#issuecomment-437675277.

"Method2" of the Yaml wiki entry shows one possible way to circumvent this limitation, but it's a bit ugly: https://github.com/autozimu/LanguageClient-neovim/wiki/yaml-language-server, it uses call LanguageClient#Notify('workspace/didChangeConfiguration', { 'settings': config }) to set a different config settings path per language on an autoload script.
