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>

* Map and abbreviation structures.
|
|
*
|
|
* The map structure is singly linked list, sorted by input string and by
|
|
* input length within the string. (The latter is necessary so that short
|
|
* matches will happen before long matches when the list is searched.)
|
|
* Additionally, there is a bitmap which has bits set if there are entries
|
|
* starting with the corresponding character. This keeps us from walking
|
|
* the list unless it's necessary.
|
|
*
|
|
* The name and the output fields of a SEQ can be empty, i.e. NULL.
|
|
* Only the input field is required.
|
|
*
|
|
* XXX
|
|
* The fast-lookup bits are never turned off -- users don't usually unmap
|
|
* things, though, so it's probably not a big deal.
