2015-07-28ui: try to fixup unicode display issuesMarc André Tanner1-0/+7
The handling of combining characters needs to be reviewed there are still strange things going on. This only covers up some of the artifacts.
2015-07-26view: always fill out complete cell matrixMarc André Tanner1-22/+8
2015-07-26vis: add infrastructure to support multiple cursors/selectionsMarc André Tanner1-10/+5
This cleans up the existing selection handling code and adds the necessary bits to eventually support multiple cursors/selections. The cursor position is kept track of using marks, which means retrieving the cursor position is no longer a constant time operation. Furthermore the terminal cursor is no longer used, instead the whole window is redrawn after every cursor movement.
2015-07-21ui: further separate curses related user interface codeMarc André Tanner1-4/+15
By now ui-curses.[hc] are the only files dealing directly with curses related functions. Integration of a proper mainloop is still pending.
2015-07-09ui: abstract curses related special keys awayMarc André Tanner1-1/+0
2015-07-09ui: unify backspace handlingMarc André Tanner1-0/+13
2015-07-09ui: move terminal state handling code to ui specific fileMarc André Tanner1-0/+11
2015-07-09ui: move input handling code to ui specific filesMarc André Tanner1-0/+42
2015-07-06Move filename from Text to FileMarc André Tanner1-15/+17
Also apply syntax rules every time the file name changes.
2015-07-03Add :show command to display special symbols for whitespacesMarc André Tanner1-1/+3
Enable/disable by setting to 0/1 respectively: :set show spaces=0 tabs=0 newlines=1
2015-04-22More renames, no functional changesMarc André Tanner1-12/+12
Win -> View, window_* -> view_*
2015-04-11Remove global mode stateMarc André Tanner1-1/+1
Once again show mode in window status bar.
2015-04-11Further ui separation, eliminate global stateMarc André Tanner1-16/+33
2015-04-07Set '< and '> marksMarc André Tanner1-18/+10

2015-04-04Fix drawing of selectionMarc André Tanner1-10/+7
2015-04-04Move more curses related stuff to ui-curses.cMarc André Tanner1-0/+7
2015-04-03Add option to display relative line numbersMarc André Tanner1-2/+14
:set rnu Based on a patch by Sebastian Götte.
2015-04-03Preliminary user interface separationMarc André Tanner1-0/+568
In theory only ui-curses.[hc] should depend on curses, however in practice keyboard input is still handled in vis.c. Furthermore the syntax definitions as well as keyboard bindings and selection code in window.c still depends on some curses constants. There is also a slight regression in that the window status bar does not show the current mode name. This and related global state should be eliminated in the future.
