Some components like hostname, progress are so simple that
the component class setup is just unnecessary boilerplate.
Allowing them to be function simplifies things.
With this you can put your regular component functions in
~/.config/nvim/lua/lualine/components/ folder and treat then as
regular lualine components just like 'mode' or 'branch'.
Hopefully this will help lualine plugins grow.
- includes modified class implementation from https://github.com/rxi/classic/blob/master/classic.lua
- now base component class is created from classic.
- change to how component classes are created.
- Don't overwrite new method to initialize a component.
Overwrite the init method. new is responsible for
creating class object and calling init on it.
Unlike previous new overwrite you don't need to create
the class (table) and return it. Instead you will recive
the object as self and do required manipulation on that
just like any most other oop langs. Also don't need to
return anything from init. init's job is to initialize.
remember to call classes init before running your operations
unfortunately lua isn't full fledged oop lang and I don't
how to automate this.
- changes how super classes are accesed.
- rename Component._parent -> Component.super
- methods on super classes now ran through super class instead
of objects _parent self._parent as that can lead to recursive inf loop.
See branch, diff, tabs, buffer classes call to init for example
on pattern.
- All components updated to reflect current logic
- component loader updated to use new initialization procedure.
- updated tests
- updated BREAKING_CHANGES.md
- plus quite a bit of formatting changes in the components
- comp.method = function(self, ...) -> function M:method(...)
