2015-07-10text: upon successfull file save store new modification timeMarc André Tanner1-7/+11
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.
2015-07-07text: avoid double close in error caseMarc André Tanner1-0/+1
2015-07-07text: remove left over debugging codeMarc André Tanner1-6/+0
2015-07-06Warn when saving a file which has been changed outside the editorMarc André Tanner1-1/+8
2015-07-06text: remove text_load_fd and text_fd_getMarc André Tanner1-29/+10
2015-07-06Move filename from Text to FileMarc André Tanner1-14/+0
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 Tanner1-38/+193
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.
2015-07-05text: store buffer allocation type (mmap or malloc)Marc André Tanner1-16/+33
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 Tanner1-16/+0
Instead use the text-dump git branch if necessary.
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
2015-06-27Make :earlier and :later accept arguments similar to vimMarc André Tanner1-8/+30
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
2015-06-27Core undo tree changesRyan Chipman1-50/+130
2015-06-24fixed some typos in commentsRyan Chipman1-2/+2
2015-04-22Cleanup line ending type detection and insertionMarc André Tanner1-7/+13
2015-04-05Introduce new struct VisTextMarc André Tanner1-24/+0
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.
2015-02-03Fix :nnn where nnn > maximal number of linesMarc André Tanner1-5/+9
2015-01-18Do not leak memory in repeated text_filename_set callsMarc André Tanner1-3/+4
2015-01-16Print debug output to stdoutMarc André Tanner1-4/+4
Stderr is used for the editor output to make usage as a filter possible.
2015-01-16Avoid possible double close when savingMarc André Tanner1-0/+1
We want close(2) to happen before rename(2). At some point the save implementation will have to be overhauled.
2015-01-11More useful error message when opening non regular filesMarc André Tanner1-1/+1

2014-10-19Preserve file permissions when savingStephen Paul Weber1-3/+10
2014-10-17Make editor usable as a filter: echo foo | vis - | catMarc André Tanner1-1/+31
The terminal output is by default redirected to stderr, making stdout available for communications purposes. If a file is "opened" from stdin (i.e. vis is given '-' as argument) and a subsequent write without a filename is performed as in ":wq" the output is written to stdout.
2014-10-17Read stdin when given - as filenameMarc André Tanner1-0/+12
2014-09-28More helpful error when trying to open a non fileMarc André Tanner1-1/+3
This is not really correct e.g. vis /dev/zero will print a misleading error.
2014-09-28Make '.' repeat last insertionMarc André Tanner1-0/+13
2014-09-28Fix typo in piece table caching layerMarc André Tanner1-1/+1
This resulted in uneccesary pieces of size 1.

2014-09-22Add support for the '<', '>' marksMarc André Tanner1-1/+1
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.
2014-09-19Remove some TODO itemsMarc André Tanner1-3/+0
2014-09-19Support files with Windows style newlines \r\nMarc André Tanner1-0/+15
2014-09-19Windows style newlines are actually \r\n not \n\rMarc André Tanner1-4/+1
This is fiddely stuff, hopefully it doesn't break too much
