2016-12-22text: remove Filepos typedefMarc André Tanner1-2/+0
The idea might be good, but it was almost unused.
2016-12-22text: introduce EMARK to denote an invalid markMarc André Tanner1-1/+3
Technically this macro name is in the reserved namespace of errno.h. The same is true for EPOS. Maybe we should rename them at some point, but for now the short names are convenient. Fix #443 Close #444
2016-12-22text: change datatype of Mark to uintptr_tMarc André Tanner1-1/+2
This should avoid undefined pointer comparisons.
2016-12-14text: expose text save method to calling codeMarc André Tanner1-1/+7
There are cases where it is useful to specify how the file should be saved.
2016-11-10vis-lua: change misnamed attribute values of `file.newlines`Marc André Tanner1-2/+2
Also rename underlying C code.
2016-04-17text: add infrastructure to save non-contiguous rangesMarc André Tanner1-0/+15
2016-02-21Cleanup new line insertion codeMarc André Tanner1-1/+2
2016-01-10text: introduce text_bytes_alloc0 utility functionMarc André Tanner1-0/+3
Heap allocates a zero terminated string of the given range. Freeing is the caller's responsibility. Checks for unsigned integer overflow i.e. passing SIZE_MAX as len will always fail because there is no room for the terminating NUL byte. This is important as EPOS is defined to be SIZE_MAX.
2015-12-31text: introduce text_newline_insertMarc André Tanner1-0/+2
2015-11-23text: introduce functions to iterate over graphemesMarc André Tanner1-1/+6
They currently consider any character for which wcwidth(3) return 0 as a combining character.
2015-10-22text: introduce text_appendf utility functionMarc André Tanner1-0/+1
2015-10-05text: add text_{v,}printf functionMarc André Tanner1-0/+3
Convenient way to insert formated data into a Text.
2015-08-08text: rename some functions to improve consistencyMarc André Tanner1-2/+2
2015-08-08text: introduce helper function text_delete_rangeMarc André Tanner1-0/+1
2015-07-28text: move utility functions to separate fileMarc André Tanner1-14/+0
2015-07-25text: add text_range_overlapMarc André Tanner1-0/+2
2015-07-22text: introduce text_range_newMarc André Tanner1-0/+3
2015-07-19vis: handle file truncation more gracefullyMarc André Tanner1-0/+3
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 Tanner1-9/+0
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 Tanner1-6/+34
2015-07-06Warn when saving a file which has been changed outside the editorMarc André Tanner1-0/+4
2015-07-06text: remove text_load_fd and text_fd_getMarc André Tanner1-4/+0
2015-07-06Move filename from Text to FileMarc André Tanner1-4/+0
Also apply syntax rules every time the file name changes.
2015-07-03Remove text dump debugging codeMarc André Tanner1-3/+0
Instead use the text-dump git branch if necessary.
2015-06-27Make :earlier and :later accept arguments similar to vimMarc André Tanner1-2/+8
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
2015-06-27Core undo tree changesRyan Chipman1-0/+2
2015-04-22Cleanup line ending type detection and insertionMarc André Tanner1-2/+9
2015-04-21Remove redundant RegexMatch definitionMarc André Tanner1-5/+1
2015-04-05Introduce new struct VisTextMarc André Tanner1-6/+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.
2015-01-06Rudimentary change list (accessible via g; and g,)Marc André Tanner1-0/+3
2015-01-02Rip out insertion repeating infrastructureMarc André Tanner1-2/+0
2015-01-01Introduce externally managed marksMarc André Tanner1-0/+4
2015-01-01Rename mark related functionsMarc André Tanner1-5/+5
2014-12-23Fix compiler warningsMarc André Tanner1-5/+5
2014-10-25Introduce text_range_sizeMarc André Tanner1-0/+1
2014-10-25Support partial writesMarc André Tanner1-0/+1
2014-10-25Support partial savesMarc André Tanner1-0/+1
2014-10-25Change return type of text_saveMarc André Tanner1-1/+1
2014-10-17Make editor usable as a filter: echo foo | vis - | catMarc André Tanner1-1/+5
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/+1
2014-09-28Make '.' repeat last insertionMarc André Tanner1-0/+2
2014-09-19Support files with Windows style newlines \r\nMarc André Tanner1-0/+2
2014-09-14Make byte based iterator API handle the whole range [0, size]Marc André Tanner1-1/+6
Before this commit the valid range was [0, size) which represents the file content. For the position at EOF (=size) a NUL byte is returned which is not actually part of the underlying file. This should fix various movements / editing operations at the end of the file. For example Ctrl+w at the end of the command prompt.
2014-09-13Introduce some helper functions dealing with FilerangeMarc André Tanner1-0/+4
2014-09-13Rename text_insert_raw to text_insertMarc André Tanner1-2/+1
2014-09-13Introduce and use EPOS instead of (size_t)-1Marc André Tanner1-1/+3
2014-09-12Introduce text_filename_setMarc André Tanner1-0/+2
This can be used to associate a given filename to a currently unnamed text.
2014-09-12Rename text_filename to text_filename_getMarc André Tanner1-1/+1
2014-09-12Restore cursor position after an undo/redoMarc André Tanner1-2/+4
2014-09-10If text has been created from an empty file, store filename upon first saveMarc André Tanner1-0/+1
