2016-01-10text: introduce text_bytes_alloc0 utility functionMarc André Tanner
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 Tanner
2015-11-23text: introduce functions to iterate over graphemesMarc André Tanner
They currently consider any character for which wcwidth(3) return 0 as a combining character.
2015-10-22text: introduce text_appendf utility functionMarc André Tanner
2015-10-05text: add text_{v,}printf functionMarc André Tanner
Convenient way to insert formated data into a Text.
2015-08-08text: rename some functions to improve consistencyMarc André Tanner

2015-07-19vis: handle file truncation more gracefullyMarc André Tanner
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 Tanner
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 Tanner
2015-07-06Warn when saving a file which has been changed outside the editorMarc André Tanner
2015-07-06text: remove text_load_fd and text_fd_getMarc André Tanner
2015-07-06Move filename from Text to FileMarc André Tanner
Also apply syntax rules every time the file name changes.
2015-07-03Remove text dump debugging codeMarc André Tanner
Instead use the text-dump git branch if necessary.
2015-06-27Make :earlier and :later accept arguments similar to vimMarc André Tanner
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

2015-04-22Cleanup line ending type detection and insertionMarc André Tanner
2015-04-21Remove redundant RegexMatch definitionMarc André Tanner
2015-04-05Introduce new struct VisTextMarc André Tanner
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.

2014-10-25Change return type of text_saveMarc André Tanner
2014-10-17Make editor usable as a filter: echo foo | vis - | catMarc André Tanner
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 Tanner
2014-09-28Make '.' repeat last insertionMarc André Tanner
2014-09-19Support files with Windows style newlines \r\nMarc André Tanner
2014-09-14Make byte based iterator API handle the whole range [0, size]Marc André Tanner
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.

This can be used to associate a given filename to a currently unnamed text.
