2017-06-15vis: promote selections to first class primitivesMarc André Tanner1-16/+6
This unifies cursors and selections. The cursor are now represendted as singleton selections.
2017-06-04Add option to hide EOF markerPhilipp Emanuel Weidmann1-0/+2
2017-04-20vis: start cleaning up register related codeMarc André Tanner1-1/+0
Now that register.h is no longer used by view.h we can move the struct and function declarations to vis-core.h.
2017-04-19vis: restructure register handlingMarc André Tanner1-2/+0
Decouple register content from cursors. Previously each cursor had exactly one corresponding register. Now each register can save a list of values whose lifetime is not tied to the cursor. If multiple cursors exist and a put with a register holding only a single value is performed, then this value is inserted at every cursor location. If there are fewer values available than cursors, then only the matching ones will be used. If a register holding multiple values is inserted in a single cursor context, only the first value will be used. Another option would be to join all existing values. The details of this behavior might be changed in the future. <C-r> in insert mode has not yet been adapted and register handling in general needs to be cleaned up further. Fix #527
2017-03-22view: rename view_dirty to view_invalidateMarc André Tanner1-1/+1
2017-03-14Restructure display codeMarc André Tanner1-17/+12
Use pull instead of push based model for display code. Previously view.c was calling into the ui frontend code, with the new scheme this switches around: the necessary data is fetched by the ui as necessary. The UI independent display code is moved out of view.c/ui-curses.c into vis.c. The cell styles are now directly embedded into the Cell struct. New UI styles are introduced for: - status bar (focused / non-focused) - info message - window separator - EOF symbol You will have to update your color themes. The terminal output code is further abstracted into a generic ui-terminal.c part which keeps track of the whole in-memory cell matrix and #includes ui-terminal-curses.c for the actual terminal output. This architecture currently assumes that there are no overlapping windows. It will also allow non-curses based terminal user interfaces.
2017-01-31view: add back link from selection to corresponding cursorMarc André Tanner1-1/+1
Can be NULL if no cursor is associated with the given selection (this is currently never the case). Avoids a loop through all cursors when clearing selections.
2017-01-13view: add infrastructure for delayed cursor destructionMarc André Tanner1-0/+7
At least one cursor (referred to as primary or main cursor) has always to exist. In the sam command language implementation we might want to dispose a cursor even if it is the primary one before later commands will create different ones (e.g. `:x/pattern/ { i/>>>/ a/<<</ }`). This commit introduces view_cursors_dispose_force. If called on the last remaining cursor, its selection is cleared and it is marked for destruction as soon as a new cursor is created. view_cursor_disposed returns the cursor marked for deletion (if any) and clears the descruction flag.
2016-10-03vis: improve cursor positioning after scrollingMarc André Tanner1-0/+4
Make cursor placement after scrolling (half) pages up/down less arbitrary. Close #390, fix #391
2016-05-22vis: refactor status line handlingMarc André Tanner1-1/+1
Make window status bar content configurable via Lua.
2016-05-22vis: consider :set horizon setting when syntax highlightingMarc André Tanner1-2/+0
2016-05-22vis: move syntax highlighting to pure Lua codeMarc André Tanner1-12/+10

2016-05-04vis: clean up cursor column displayMarc André Tanner1-7/+2
2016-04-27view: change view_cursors_place to take 1 based column numberMarc André Tanner1-0/+1
This should fix inconsistency in the Lua API.
2016-04-19vis: add :set horizon optionDavid B. Lamkins1-0/+2
Can be used to specify the number of bytes before the visible area to consider for syntax highlighting. Defaults to 32K for now, whereas before it was 16K.
2016-04-15view: add view_cursors_place(cursor, line, col) functionMarc André Tanner1-0/+1
2016-04-15view: add view_cursors_col functionMarc André Tanner1-0/+2
2016-04-15view: add view_cursors_line functionMarc André Tanner1-0/+2
2016-04-13view: add view_cursors_new_force functionMarc André Tanner1-1/+6
To create a cursor even if there already exists one at the same position. Should only be used if all but one of the cursors will later be removed.
2016-04-08vis: indicate primary cursor number in status barMarc André Tanner1-0/+2
If there exist multiple cursors, [n/m] is added to the status bar. Meaning the n-th cursor out of the existing m cursors is currently the primary one.
