Huge change to internal mechanics.
- Now %{%expr%} blocks are used for evaluating statusline instead of
%!expr . Pros for this is statusline is evaluated on current win and
buf context instead of active win & bufs context.
- Now all components branch & diff(These two are cached) including users
function components updates on inactive status.
- now components update status and function components receive an
argument (is_focused) when called. It indicates whether it's running
for active or inactive statusline.
- Now lualine no longer aggrasively takes over 'statusline' option.
instead it sets the global version of statusline option. So it's
possible to unset it to hide lualine . Or set buffer local version
of that option to have different statusline then lualine on thay
buffer
- Switch vim.o to vim.go or vim.opt.
- BugFix autcommands being set everytime an instence of diff or branch
component is created
- Added new utils functions define_autocmd & is_focused
- Remove utils function lualine_eval
- Removed hacky require cache modification from component.lua
