2017-05-03text: remove text_history_get functionMarc André Tanner1-3/+0
As currently implemented this does not properly integrate with multiple cursor support. The functionality should be provided in a layer higher up. The jumplist and changelist need to be redesigned, for now they are broken.
2017-05-03text: remove text_iterate macroMarc André Tanner1-5/+0
2017-05-03text: remove text_insert_newline functionMarc André Tanner1-2/+0
This is no longer needed because we always insert \n never \r\n.
2017-05-03text: remove count argument from text_{earlier,later}Marc André Tanner1-2/+2
2017-05-03text: add miscellaneous documentation sectionMarc André Tanner1-8/+11
2017-05-03text: rename text_sigbus to text_mmapedMarc André Tanner1-3/+5
Add casts to uintptr_t to avoid unrelated pointer comparisons.
2017-05-03text: convert comments to doxygen formatMarc André Tanner1-84/+293
2017-04-09vis: remove handling of \r\n line endingsMarc André Tanner1-9/+0
Use something like dos2unix(1) and unix2dos(1), if you need to edit such files.
2017-04-09text: drop special handling of \r\n line endingsMarc André Tanner1-6/+0
2017-04-09text: add mem{r,}chr(3) based byte search functionsMarc André Tanner1-0/+2
These are generally implemented efficiently in libc. While memrchr(3) is non-standard, it is a common extension. If it is not available, we use a simple C implementation from musl.
2017-04-08text: introduce text_char_get which converts \r\n to \nMarc André Tanner1-0/+3
2017-02-25text: add iterator accessor function which translates \r\n to \nMarc André Tanner1-0/+3
2016-12-23Apply format string attribute to printf style functionsMarc André Tanner1-2/+2
Not strictly C99 conform, but widely supported and easy enough to NOP for compilers which do not support it. Besides it was already used to mark certain functions as noreturn.
2016-12-23text: make text_vprintf static, it is only used within text.cMarc André Tanner1-1/+0
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
