This is a prerequisite for the next commit.
The incumbent code was wrong: the test of $in_redirection in the first hunk
would never have seen «(( in_redirection == 2 ))». That had no visible
effect since options to sudo don't look like redirection operators.
Special handling for cursor imprint or partial path highlighting
is needed in more cases than accept-*. For example when accepting
a line from isearch, no accept-* widget is invoked.
The proper way is to use zle-line-finish.
Trumps #259.
Fixes#284.
If the separator feature is disabled, this makes it possible to
change the main 'path' styles in a running session without the
need to touch the '_pathseparator' styles, too.
Assignments to positional parameters using scalar assignment syntax is
a feature: it is covered by upstream's test suite ("append to positional
parameter" in Test/A06assign.ztst).
This commit is based on the work done by
Jorge Israel Peña (blaenk) in #136.
Changes:
* Adjusted to changes on the latest master branch.
* Use regular path highlighter colors by default.
* Break out early if the separator color is the same to
improve performance.
* Tests.
If possible, try to use the zsh/parameter module to get
information about a shell words.
This avoids subshells and is a huge speed improvement
on systems such as cygwin.
Note 1:
$commands does not know about PATH_DIRS. So in case
PATH_DIRS is set, 'type -w' is still used if nothing
else matches.
Note 2:
zsh/parameter can't distinguish between 'command' and
'hashed'. Adjusted the test for that case to XFAIL.
The ideal solution would be if whence had an option to
put the result in REPLY instead of printing it to stdout.
Consider indexing long buffers (say 300 chars). E.g. following line:
integer offset=${${buf[start_pos+1,len]}[(i)$needle]}
will gradually go into large indices for first index [a,] and be kept
at large index for second index [,b]. Instead, we can remove already
processed characters from buf:
proc_buf="${proc_buf[offset + $#arg + 1,-1]}"
$offset and $#arg are small, first index will not be large. $proc_buf
will be smaller and smaller and the second index [,-1] will run shorter
and shorter.
_zsh_highlight_add_highlight appends to region_highlight $1 $2 and the
next non-null parameter. If there is no non-null parameter, do nothing,
This is so that highlighters can add a style with fallbacks if the most
specific style is not defined. If none of the applicable styles are
defined, do the right thing and don't add an invalid entry to
region_highlight.
The pattern highlighter doesn't use this function as it'd need too large
of an API change.
zsh older than workers/28418 (zsh revision 23bdfc7fd2)
doesn't support the «${name:offset:length}» syntax. Therefore, use the older
«$name[start,end]» syntax instead.
Followup to 3cb58fd7d7b9e42067ffcf24892114dc2c9b26e4, "Optimization: -1 is
extra computation of string length internally".

The important part of this change is removing the second conjunct from the
condition; the remainder of the change gives one example of when that matters.
