How to open chat in right split window by CopilotChat.

[yfujita-skgcat]

Is there any simple way to display the chat from the CopilotChat command in a split window on the right side?

I read "rplugin/python3/CopilotChat/mypynvim/core/buffer.py" and found self.nvim.api.command(f"vsplit | buffer {self.buf.handle}").
I inserted "wincmd l" as follows and succeeded in open chat in right side.

    def vsplit(self, opts: dict[str, Any] = {}):
        # self.nvim.api.command(f"vsplit | buffer {self.buf.handle}")
        self.nvim.api.command(f"vsplit | wincmd l | buffer {self.buf.handle}")
        winnr = self.nvim.api.get_current_win()
        for opt, val in opts.items():
            self.nvim.api.win_set_option(winnr, opt, val)

Is there any other way than modifying the source code?

set splitright if you want to have it globally (which is imo the most sane default)
and set splitbelow for horizontal split

For the future visitors, this is the change that makes chat to open on the right:

vim.opt.splitright = true

I know you asked about doing without modifying the code, but it is literally a one character change. Change this

function! CopilotChat()
  call LoadConfig() 
  call ConfirmSignin()
  vsplit
...

to this

function! CopilotChat()
  call LoadConfig() 
  call ConfirmSignin()
  split
...

in copilot_chat.vim

Whoops, that is for this repo: https://github.com/DanBradbury/copilot-chat.vim for vim. I imagine there is something similar here
