New issue 297 by [email protected]: Multibyte in langmap (lhs) gets not
handled properly in mapping
https://code.google.com/p/vim/issues/detail?id=297
What steps will reproduce the problem?
1. :set langmap=öc
2. :map col :set list!
3. Press: öol
What is the expected output? What do you see instead?
The list setting should have been toggled, but the mapping gets aborted
after "öo".
Using "öap" to change a paragraph works.
This is related to the langmap lhs character being multibyte, it works
with "langmap=dc".
What version of the product are you using? On what operating system?
7.4.552
Please provide any additional information below.
It's probably some issue where multibyte characters in mappings are not
handled properly in `do_map` or somewhere similar.
It might be related to this code:
if (mp->m_keys[0] == c1
&& (mp->m_mode & local_State)
&& ((mp->m_mode & LANGMAP) == 0
|| typebuf.tb_maplen == 0)
)
{
#ifdef FEAT_LANGMAP
int nomap = nolmaplen;
int c2;
#endif
/* find the match length of this mapping */
for (mlen = 1; mlen < typebuf.tb_len; ++mlen)
{
#ifdef FEAT_LANGMAP
c2 = typebuf.tb_buf[typebuf.tb_off + mlen];
if (nomap > 0)
--nomap;
else if (c2 == K_SPECIAL)
nomap = 2;
else
LANGMAP_ADJUST(c2, TRUE);
if (mp->m_keys[mlen] != c2)
#else
if (mp->m_keys[mlen] !=
typebuf.tb_buf[typebuf.tb_off + mlen])
#endif
break;
}
