Suggestive patch for simplified completion
NOTE: The patch is largely untested. Modifications: - Update readme.org - Remove geiser-company - Move Company extensions to geiser-completion Omissions: - geiser-company--inhibit-autodoc has been removed. Eldoc handling should be implemented in the frontend, not in the backend. See for example: https://github.com/minad/corfu/blob/04fbfce3d7e9c125a7fd22a34455a508247a522b/corfu.el#L1212 - The quickhelp-string action and geiser-company--docstring have been removed. company-quickhelp can use `:company-doc-buffer` instead with minimal overhead. See: https://github.com/company-mode/company-quickhelp/blob/3ca2708b4e5190205aca01d65fe1b391963a53f9/company-quickhelp.el#L138 - The automatic Company setup has been removed. Personally I am not a fan of such auto configuration. It is better if completion is configured consistently in the user configuration. You may want to restore the auto configuration for backward compatibility. It depends on your backward compatibility story. I am fine with rare breaking changes from time to time. - There is a cyclic dependency between geiser-edit/geiser-doc and geiser-completion, which should be untangled.
