2015-07-28vis: fix bugs uncovered by coverity scanMarc André Tanner
2015-07-28vis: fix join operatorMarc André Tanner
Only skip last line break if range comes from linewise visual mode.
2015-07-28vis: pass cursor to operator implementationsMarc André Tanner
2015-07-28text-util: introduce text_range_equalMarc André Tanner
2015-07-28text-object: introduce utility function text_range_is_linewiseMarc André Tanner
2015-07-28vis: use multiple cursor/selection infrastructureMarc André Tanner
This commits introduces the following keybindings, in normal mode: CTRL-N select word the cursor is currently over, switch to visual mode CTRL-P remove least recently added cursor ESC if a selection is active, clear it. Otherwise dispose all but the primary cursor. In visual mode: CTRL-N create new cursor and select next word matching current selection CTRL-X clear (skip) current selection, but select next matching word CTRL-P remove least recently added cursor
2015-07-28vis: do not move cursor in multicursor mode after undo/redoMarc André Tanner

2015-07-28vis: ESC in normal mode clears all cursorsMarc André Tanner
2015-07-28vis: add per cursor registersMarc André Tanner
2015-07-28vis: add an operator to create new cursorsMarc André Tanner
The operator creates a new cursor at the start of every line covered by the given range. It is currently only available as CTRL+O in visual mode.
2015-07-28text-motion: add functions to iterate over lines of a rangeMarc André Tanner
2015-07-28text-util: add text_range_containsMarc André Tanner
2015-07-28text: move utility functions to separate fileMarc André Tanner
2015-07-28ui: try to fixup unicode display issuesMarc André Tanner
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: use a mark to keep track of the visible areaMarc André Tanner
This should fix "corruptions" caused by wrong offsets when editing the same file in multiple windows.
2015-07-26view: do not set cursor position after resizeMarc André Tanner
The problem is that a cursor movement might cause a redraw which in turn causes the sidebar width to change thus the view to be resized which will override the cursor position.
2015-07-26view: always fill out complete cell matrixMarc André Tanner
2015-07-26vis: add infrastructure to support multiple cursors/selectionsMarc André Tanner
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.
2015-07-26text-object: add new functions to search for wordsMarc André Tanner
2015-07-25text: handle marks set to 0 and text_size(...)Marc André Tanner
2015-07-25text: add text_range_overlapMarc André Tanner
2015-07-24text-motion: introduce text_line_{up,down}Marc André Tanner
2015-07-23text-object: add text_range_linewiseMarc André Tanner
Takes a range and extends both ends to cover the remaining part of the line.
2015-07-22text: introduce text_range_newMarc André Tanner
2015-07-21ui: further separate curses related user interface codeMarc André Tanner
By now ui-curses.[hc] are the only files dealing directly with curses related functions. Integration of a proper mainloop is still pending.
2015-07-20vis: improve insertion of verbatim characters via CTRL-V in insert modeMarc André Tanner
Recognized formats are: CTRL-V nnn decimal value nnn CTRL-V onnn or CTRL-V Onnn octal value nnn CTRL-V xnn or CTRL-V Xnn hex value nn CTRL-V unnnn Unicode codepoint nnnn CTRL-V Unnnnnnnn Unicode codepoint nnnnnnnn Leading zeros can be omitted, any illegal character for the given format will be ignored and terminates the numerical code.
2015-07-19vis: handle file truncation more gracefullyMarc André Tanner
If we use the file / virtual memory system as cache (using mmap(2)) and another process truncates the file we are editing, we have a problem. All we can do is catch the resulting SIGBUS, close the corresponding window and print a warning message. To test this use: $ dd if=/dev/zero of=TEST bs=8M count=1 $ vis TEST :! echo TRUNCATE > TEST
2015-07-19text: move regex related functions to separate fileMarc André Tanner
Eventually this should probably be rewritten to use an iternal regex engine, currently it has unacceptable memory usage, it copies the whole text.
2015-07-19text: slight cleanup, add a few commentsMarc André Tanner
2015-07-11vis: rename struct member to avoid conflict with standard libraryMarc André Tanner
Closes #60
2015-07-10vis: add a file open dialogMarc André Tanner
For this to work make sure you have vis-open and slmenu or dmenu somewhere in $PATH. For now the file dialog is shown for :open, :split and :vsplit when the argument is either . (a dot) or looks like a file pattern. For example :open *.[ch] will show a listing of all C source and header files in the current directory. Use a fuzzy search to make your choice.
2015-07-10vis: fix detection of file changes outside the editorMarc André Tanner
2015-07-10text: upon successfull file save store new modification timeMarc André Tanner
2015-07-09ui: abstract curses related special keys awayMarc André Tanner
2015-07-09ui: unify backspace handlingMarc André Tanner
2015-07-09ui: move terminal state handling code to ui specific fileMarc André Tanner
2015-07-09ui: move input handling code to ui specific filesMarc André Tanner
2015-07-09vis: improve handling of linewise deletion at end of fileMarc André Tanner
dd on the last line now moves the cursor to the start of the preceding line.
2015-07-08vis: make J (join) behave like in vim when given a countMarc André Tanner
2015-07-08vis: only read file content from stdin if - was specifiedMarc André Tanner
This allows to feed keyboard input from a file as in: cat keyboard-input | vis input-file which will be used for testing purposes.
2015-07-07text: safer temporary file creationMarc André Tanner
Set umask before calling mkstemp. According to POSIX 2008 this is not necessary since the temporary file is guaranteed to be created with permission restricted to the current user. However this is more secure on non-conforming systems and safe as long as we do not use multiple threads. Fixes Coverity CID 101333.
2015-07-07view: properly NUL terminate whitespace replacement symbolsMarc André Tanner
This should not be a problem in practice, since cell->data is large enough anyway.
2015-07-07text: avoid double close in error caseMarc André Tanner
2015-07-07text: remove left over debugging codeMarc André Tanner
2015-07-06Make selection contiguous over whitespace symbolsMarc André Tanner
