/*
 * spell.c: code for spell checking
 *
 * The spell checking mechanism uses a tree (aka trie).  Each node in the tree
 * has a list of bytes that can appear (siblings).  For each byte there is a
 * pointer to the node with the byte that follows in the word (child).
 *
 * A NUL byte is used where the word may end.  The bytes are sorted, so that
 * binary searching can be used and the NUL bytes are at the start.  The
 * number of possible bytes is stored before the list of bytes.
 *
 * The tree uses two arrays: "byts" stores the characters, "idxs" stores
 * either the next index or flags.  The tree starts at index 0.  For example,
 * to lookup "vi" this sequence is followed:
 *	i = 0
 *	len = byts[i]
 *	n = where "v" appears in byts[i + 1] to byts[i + len]
 *	i = idxs[n]
 *	len = byts[i]
 *	n = where "i" appears in byts[i + 1] to byts[i + len]
 *	i = idxs[n]
 *	len = byts[i]
 *	find that byts[i + 1] is 0, idxs[i + 1] has flags for "vi".
 *
 * There are two word trees: one with case-folded words and one with words in
 * original case.  The second one is only used for keep-case words and is
 * usually small.
 *
 * There is one additional tree for when not all prefixes are applied when
 * generating the .spl file.  This tree stores all the possible prefixes, as
 * if they were words.  At each word (prefix) end the prefix nr is stored, the
 * following word must support this prefix nr.  And the condition nr is
 * stored, used to lookup the condition that the word must match with.
 *
 * Thanks to Olaf Seibert for providing an example implementation of this tree
 * and the compression mechanism.
 * LZ trie ideas:
 *	http://www.irb.hr/hr/home/ristov/papers/RistovLZtrieRevision1.pdf
 * More papers: http://www-igm.univ-mlv.fr/~laporte/publi_en.html
 *
 * Matching involves checking the caps type: Onecap ALLCAP KeepCap.
 *
 * Why doesn't Vim use aspell/ispell/myspell/etc.?
 * See ":help develop-spell".
