2015-07-09ui: unify backspace handlingMarc André Tanner2-9/+17
2015-07-09ui: move terminal state handling code to ui specific fileMarc André Tanner3-3/+15
2015-07-09ui: move input handling code to ui specific filesMarc André Tanner4-37/+50
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.
2015-07-07text: safer temporary file creationMarc André Tanner1-1/+4
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 Tanner1-3/+3
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 Tanner1-0/+1
2015-07-07text: remove left over debugging codeMarc André Tanner1-6/+0
2015-07-06Make selection contiguous over whitespace symbolsMarc André Tanner1-2/+3
2015-07-06Warn when saving a file which has been changed outside the editorMarc André Tanner5-2/+24
2015-07-06text: remove text_load_fd and text_fd_getMarc André Tanner5-64/+33
2015-07-06Move filename from Text to FileMarc André Tanner8-65/+58
Also apply syntax rules every time the file name changes.
2015-07-06text: overhaul file load implementationMarc André Tanner1-3/+34
Files smaller than 8M are now copied into an internal buffer upon load. Thus they can be safely truncated. Larger files are memory mapped and use the file/virtual memory system as caching layer. Hence truncating them will corrupt the file content. Eventually the resulting SIGBUS should be handled gracefully.
2015-07-06text: overhaul save implemenationMarc André Tanner2-39/+207
Try to do an atomic save using rename(2) unless * the file is a symbolic link * the file is a hard link * file ownership can not be preserved * file group can not be preserved * POSXI ACL can not be preserved (if enabled) * SELinux security context can not be preserved (if enabled) in which case the file is overwritten in place. However a failure to do so results in data loss. Closes #47.
2015-07-05make: only call uname once in config.mkMarc André Tanner1-6/+8
2015-07-05text: store buffer allocation type (mmap or malloc)Marc André Tanner1-16/+33
2015-07-03Add movements to next/previous character within same lineMarc André Tanner3-0/+25
These movements always keep the cursor on the same line and do not move over newlines.
2015-07-03Do not take a snapshot in text_range_writeSilvan Jegen1-2/+0
Since text_range_write is called several times in cmd_filter, the undo command does not undo the whole filter operation but only up to the last call of text_range_write. Removing the snapshot-taking code solves this issue.
2015-07-03Remove text dump debugging codeMarc André Tanner2-19/+0
Instead use the text-dump git branch if necessary.
2015-07-03Fix handling of multibyte characters (at start of display area)David B. Lamkins1-1/+3
Previously a sequence of Unicode REPLACEMENT CHARACTER was displayed. Use an explicitly initialized mbstate_t object in the call to mbrtowc(). While this should not strictly be necessary, it works around a bug in certain implementations. Closes #56.
2015-07-03Add :show command to display special symbols for whitespacesMarc André Tanner6-17/+149
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 Tanner3-44/+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 Tanner6-120/+69
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
2015-06-28Fix copy/paste error in text_restoreMarc André Tanner1-1/+1
This really needs some unit tests.
2015-06-28Replace a->time with a->seq in history_traverse_toRyan Chipman1-3/+3
2015-06-28Add seq field to Action structRyan Chipman1-0/+8
2015-06-27Add more thorough description of history to READMERyan Chipman1-11/+16
2015-06-27Make :earlier and :later accept arguments similar to vimMarc André Tanner4-31/+90
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
2015-06-27Mark internal undo tree functions as staticMarc André Tanner1-4/+4
2015-06-27Edit README to reflect new history implementationRyan Chipman1-6/+10
2015-06-27Hook up :-commands & keybindings for earlier/laterRyan Chipman2-0/+45
2015-06-27Core undo tree changesRyan Chipman2-50/+132
2015-06-24fixed some typos in commentsRyan Chipman1-2/+2
2015-06-04Use $(MAKE) instead of directly calling `make`Michael Reed1-1/+1
This fixes `make debug` on OpenBSD (and possibly other systems) where /usr/bin/make isn't GNU make.
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 Tanner2-26/+21
2015-05-17Filter command :!Marc André Tanner3-0/+219
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.
2015-05-16Release macro dataMarc André Tanner2-1/+5
2015-05-16Cleanup general purpose buffer APIMarc André Tanner6-21/+30
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.
2015-05-16Let 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 Linares2-1/+8
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.
