This is the gsoc-2011 project to clean up and backport multibyte support from other nvi forks in a form we can use. USE_WIDECHAR is on unless building for the rescue crunchgen. This should allow editing in the native locale encoding. USE_ICONV depends on make.conf having 'WITH_ICONV=YES' for now. This adds the ability to do things like edit a KOI8-R file while having $LANG set to (say) en_US.UTF-8. iconv is used to transcode the characters for display. Other points: * It uses gencat and catopen/etc instead of homegrown msg catalog stuff. * A lot of stuff has been trimmed out, eg: the perl and tcl bindings which we could never use in base anyway. * It uses ncursesw when in widechar mode. This could be interesting. GSoC info: http://www.google-melange.com/gsoc/proposal/review/google/gsoc2011/zy/1 Repo at: https://github.com/lichray/nvi2 Obtained from: Zhihao Yuan <lichray@gmail.com>

* The MARK and LMARK structures define positions in the file. There are
|
|
* two structures because the mark subroutines are the only places where
|
|
* anything cares about something other than line and column.
|
|
*
|
|
* Because of the different interfaces used by the db(3) package, curses,
|
|
* and users, the line number is 1 based and the column number is 0 based.
|
|
* Additionally, it is known that the out-of-band line number is less than
|
|
* any legal line number. The line number is of type recno_t, as that's
|
|
* the underlying type of the database. The column number is of type size_t,
|
|
* guaranteeing that we can malloc a line.
