2015-07-28text: move utility functions to separate fileMarc André Tanner1-0/+1
2015-07-26vis: add infrastructure to support multiple cursors/selectionsMarc André Tanner1-111/+106
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 Tanner1-2/+2
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 Tanner1-7/+58
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 Tanner1-0/+35
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
2015-07-11vis: rename struct member to avoid conflict with standard libraryMarc André Tanner1-2/+2
Closes #60
2015-07-10vis: add a file open dialogMarc André Tanner1-19/+58
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 Tanner1-2/+2
2015-07-09ui: move terminal state handling code to ui specific fileMarc André Tanner1-3/+2
2015-07-09ui: move input handling code to ui specific filesMarc André Tanner1-28/+1
2015-07-09vis: improve handling of linewise deletion at end of fileMarc André Tanner1-3/+6
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 Tanner1-0/+2
2015-07-08vis: only read file content from stdin if - was specifiedMarc André Tanner1-1/+1
This allows to feed keyboard input from a file as in: cat keyboard-input | vis input-file which will be used for testing purposes.
2015-07-06Warn when saving a file which has been changed outside the editorMarc André Tanner1-1/+10
2015-07-06text: remove text_load_fd and text_fd_getMarc André Tanner1-13/+22
2015-07-06Move filename from Text to FileMarc André Tanner1-6/+9
Also apply syntax rules every time the file name changes.
2015-07-03Add movements to next/previous character within same lineMarc André Tanner1-0/+4
These movements always keep the cursor on the same line and do not move over newlines.
2015-07-03Add :show command to display special symbols for whitespacesMarc André Tanner1-0/+32
Enable/disable by setting to 0/1 respectively: :set show spaces=0 tabs=0 newlines=1
2015-06-30Fix segfault in cmd_filterMarc André Tanner1-3/+3
Using FD_ISSET on negative file descriptors results in breakage. Closes #55.
2015-06-30Perform character prev/next movements based on Text not ViewMarc André Tanner1-2/+2
While it is slower, it allows to move to characters which are currently not visible. This will be handy when experimenting with multiple cursors.
2015-06-30Cleanup insert/replace mode input handlingMarc André Tanner1-17/+5
View should only display the file content, but not modify it.
2015-06-28Do not take address of variables which go out of scopeMarc André Tanner1-4/+4
This is a bit of a hack, since now the callers range is modified. The various cmd_* functions should probably take a const Filerange pointer as argument and modify a local Filerange variable if needed.
2015-06-28Mark intentional case statement fall throughMarc André Tanner1-3/+3
2015-06-27Make :earlier and :later accept arguments similar to vimMarc André Tanner1-19/+50
Currently the following arguments are accepted: {count} Go to older text state {count} times. {N}s Go to older text state about {N} seconds before. {N}m Go to older text state about {N} minutes before. {N}h Go to older text state about {N} hours before. {N}d Go to older text state about {N} days before
2015-06-27Hook up :-commands & keybindings for earlier/laterRyan Chipman1-0/+41
2015-05-17Implement :substitute by invoking sed as a filterMarc André Tanner1-2/+5
2015-05-17Implement :r and :r! in terms of filter commandsMarc André Tanner1-25/+20
2015-05-17Filter command :!Marc André Tanner1-0/+216
If no range is given then stdin is passed through which allows interactive usage as in :!ls -1 *.c | slmenu For this to work the command needs to use stderr for its user interface and write any data for vis to stdout.
2015-05-16Let each :-command decide what to do if no range is specifiedMarc André Tanner1-1/+2
2015-05-16Improve parsing of :-command name and parametersSilvan Jegen1-8/+16
2015-05-14In command mode make the '.' range specifier match the current lineMarc André Tanner1-1/+5
2015-05-07Add '--' as end of optionsMatias Linares1-1/+5
Now it works properly, `vis -- -v` edit a file named `-v`. Also added the proper info to the man page.
2015-05-06Use the command name without the Filerange in argvSilvan Jegen1-1/+1

2015-04-29Move redrawing out of operator implementationsMarc André Tanner1-13/+15
Note that currently all windows are redrawn, this could be further optimized to only redraw the affected windows.
2015-04-29Make operators return new cursor positionMarc André Tanner1-36/+41
2015-04-22Cleanup line ending type detection and insertionMarc André Tanner1-2/+11
2015-04-22Fix echo foo | vis -Marc André Tanner1-6/+8
A single '-' indicates read from stdin. Also adjust coding style.
2015-04-22for editor command compare string, not just first characterChristian Hesse1-1/+1
Signed-off-by: Christian Hesse <mail@eworm.de>
2015-04-22make vis print version with command option -vChristian Hesse1-3/+6
The man page states this is possible, so add the code. Signed-off-by: Christian Hesse <mail@eworm.de>
2015-04-22Rename window.[ch] to view.[ch]Marc André Tanner1-1/+1
2015-04-22Yet more renames (EditorWin -> Win)Marc André Tanner1-6/+6
2015-04-22More renames, no functional changesMarc André Tanner1-82/+82
Win -> View, window_* -> view_*
2015-04-22More renaming vis->win->view instead of vis->win->winMarc André Tanner1-47/+47
2015-04-22Better variable naming (VisText -> File)Marc André Tanner1-50/+50
Therefore vis->win->text->data becomes vis->win->file->text.
2015-04-21Make '.' respect countMarc André Tanner1-0/+3
2015-04-21Mark some movements as idempotentMarc André Tanner1-3/+3
2015-04-21Make 'n', 'N', '*', '#' respect countMarc André Tanner1-25/+21
2015-04-21Handle failure of a movement gracefullyMarc André Tanner1-0/+1
This for example fixes movements to unset marks.
2015-04-21Cleanup implementation of movements to marksMarc André Tanner1-8/+10
2015-04-21Further clean up to/till movementsMarc André Tanner1-22/+16
This makes them respect count i.e. something like 3f{char} should work.
