Is it possible to assign a function to keymaps in Lspsaga finder config ?

[eshepelyuk]

Hello

I would like to use this plugin https://github.com/nvim-focus/focus.nvim to open LSP references files
insted of using native split.
Is it possible to assign a function to finder.keys so I could call other plugin funcions.

Smth like

require('lspsaga').setup({
  finder = {
    keys = {
      on_open = function(params_with_file_path) 
      .....
      end
    }
  }
})

Proposed a possible solution in the finder tool #1523 if you'd like to weigh in.

After for poking around there is a way to achieve that behavior with the existing APIs.

First, you will need to define a custom command like the following:

vim.api.nvim_create_user_command(
  "MyCustomCommand",
  function (opts)
    local filepath = opts.fargs[1]
    print("MyCustomCommand filepath=", filepath)
  end,
  {
    nargs = 1,
    complete = "file",
  }
) 

Then in the setup you can use the following:

require('lspsaga').setup({
  finder = {
    keys = {
      "open_or_toggle" = "p",
      "MyCustomCommand" = "o",
    },
  },
})

That will fire your custom command function if you press o in the lspsaga finder window. That said I don't love having to define commands just for this one plugin, I've drafted #1525 so it's more direct without breaking the original keys api contract.
