Instance Method Details

#col ⇒ Object

Returns the current column position of the cursor in the Vim server

This method queries the specified Vim server for the current cursor position using Vim’s remote expression feature. It executes a Vim command that returns the result of ‘col(’.‘)`, which represents the current column number (1-indexed) of the cursor position.

end

#default_server_name ⇒ Object

The default server name is derived from the current working directory It converts the absolute path to uppercase for consistent identification This approach ensures each working directory gets a unique server identifier The server name format makes it easy to distinguish different Vim sessions
