Feature request: per-buffer/window options

[runiq]

I'd like to be able to set the virtual text prefix to the current filetype's comment string, so I can copy stuff out of the terminal and e.g. paste it into a REPL.

Thanks for this addon, it's great :)

You can do this with Vim by using after and ftplugin files. Just make sure filetype plugin on is in your init.vim.

For example, in the folder that your init.vim goes, you could this to a file named after/ftplugin/<filetype>/diagnostic.vim:

let g:diagnostic_virtual_text_prefix = '<comment string>'

Perhaps a b: version of the variables also would work here.

What about making things configurable at the on_attach() level? As in, give the on_attach() function an optional config table with keys that correspond to the g:diagnostic_* options.

Would you consider a PR that implements those?
