2015-10-15ui: cleanup redrawingMarc André Tanner1-2/+2
2015-10-14vis: introduce special keys which allow mappings to editor actionsMarc André Tanner1-0/+9
Key bindings in vis are always recursive, hence mapping ~ to ~l will cause an infinite loop. Instead vis supports special editor "keys" which map to internal editor functions. As an example one can thus map ~ to <vis-operator-case-swap>l or even <vis-operator-case-swap><cursor-char-next> Furthermore this makes it possible to completely unmap core editor features such as operators, the corresponding funtionality is still available via its corresponding special key.
2015-10-14view: cleanup option handlingMarc André Tanner1-5/+1
2015-10-05vis: rework input handling using libtermkeyMarc André Tanner1-0/+21
Key bindings are now specified as symbolic key strings, this will eventually allow run time configurable key mappings. This introduces a bulid time dependency on libtermkey which can be found at: http://www.leonerd.org.uk/code/libtermkey/
2015-08-09vis: fix :edit! commandMarc André Tanner1-4/+7
It now correctly re-edits the file (i.e reloads it from disk).
2015-07-28text: move utility functions to separate fileMarc André Tanner1-0/+1
2015-07-26vis: add infrastructure to support multiple cursors/selectionsMarc André Tanner1-25/+9
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 Tanner1-7/+1
By now ui-curses.[hc] are the only files dealing directly with curses related functions. Integration of a proper mainloop is still pending.
2015-07-19vis: handle file truncation more gracefullyMarc André Tanner1-0/+2
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
2015-07-06Warn when saving a file which has been changed outside the editorMarc André Tanner1-0/+1
2015-07-06text: remove text_load_fd and text_fd_getMarc André Tanner1-17/+0
2015-07-06Move filename from Text to FileMarc André Tanner1-19/+25
Also apply syntax rules every time the file name changes.
2015-06-30Cleanup insert/replace mode input handlingMarc André Tanner1-19/+42
View should only display the file content, but not modify it.
2015-05-16Release macro dataMarc André Tanner1-0/+2
2015-05-16Cleanup general purpose buffer APIMarc André Tanner1-2/+2
Introduce buffer_init to initialize a stack allocated buffer. Rename buffer_{alloc,free} functions because they do something different than the usual convention. They operate on the underlying buffer data but do not allocate/free an actual Buffer struct.
2015-04-22Yet more renames (EditorWin -> Win)Marc André Tanner1-29/+29
2015-04-22More renames, no functional changesMarc André Tanner1-24/+24
Win -> View, window_* -> view_*
2015-04-22More renaming vis->win->view instead of vis->win->winMarc André Tanner1-22/+21
2015-04-22Better variable naming (VisText -> File)Marc André Tanner1-82/+82
Therefore vis->win->text->data becomes vis->win->file->text.
2015-04-21Improve loading of filesMarc André Tanner1-1/+6
This fixes a segmentation fault when opening a directory. Also, opening a file you are not permitted to read, will now give an error, instead of showing the file as empty. Based on a patch by Willem van de Krol.
2015-04-11Eliminate global state for repetition of last modificationMarc André Tanner1-0/+1
2015-04-11Eliminate global state for :set optionsMarc André Tanner1-0/+1
2015-04-11Lazy initialization of :-commandsMarc André Tanner1-0/+1
2015-04-07Set '< and '> marksMarc André Tanner1-5/+20
2015-04-05Introduce new struct VisTextMarc André Tanner1-62/+89
This adds yet another layer of indirection and stores vi related stuff which is associated with a given text but shared among all windows displaying it (e.g. marks). This will also help if one wants to keep texts arround which aren't currently displayed.
2015-04-03Preliminary user interface separationMarc André Tanner1-329/+59
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.

2014-09-19This fixes warning with latest glibc (>= 2.19.90), which deprecated _BSD_SOURCEChristian Hesse1-0/+1
warning: _BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE Commit 4f537d8e4bd9707a0048289f296510b76ce6d642 just fixed one of three cases. Fix the remaining.
2014-09-19Implement expand tab functionality, make tabwidth configurableMarc André Tanner1-0/+13
If expandtab is enabled then inserted tabs are replaced by tabwidth amount of spaces. Both settings apply to all windows files and can be changed via: :set tabwidth n # where 1 <= n <= 8 :set expandtab (1|yes|true)|(0|no|false)
2014-09-18Do only open an empty buffer if the file does not existMarc André Tanner1-1/+1
Opening a file without having read permissions should fail.
