Several extensions trigger custom actions. Make sure, those actions are
only performed, if airline is actually active and not temporarily
disabled using e.g. :AirlineToggle
under certains circumstances it could happen that for the vim-ctrlspace
tabline extension a tabline group was redefined which would cause a
separator having foreground and background color swapped. This was
caused by using the 'pos' parameter for the right side wrongly.
fixes#1559
tabline
Solution: Add a new option which inverses the position of buffer and
tabs
If switch_buffer_and_tabs is 0 (default) buffer are on the left and tabs
on the right else if is 1 the order is reversed.
Solution: Use the current one from ctrlspace 5.0 + minor style fixes
Problem: CtrlSpace 5.0 does no longer work with airline
Solution: Modify the ctrlspace extension to call the new APIs
The statusline work fine but the custom ctrlspace function
somehow/somewhere gets overridden and I could not figure out where.
Therefore the user must add
let g:CtrlSpaceStatuslineFunction = "airline#extensions#ctrlspace#statusline()"
to its .vimrc.
Problem: Ctrlspace 5.0 does not integrate well into tabline
Solution: Write a tabline extensions for ctrlspace 5.0.
The extensions is capable of showing both tabs and buffers, but only the
buffers of a current tab are shown.
