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 $2 and the
next non-null parameter. If there is no non-null parameter, do nothing,
This is so that highlighters can add a style with fallbacks if the most
specific style is not defined. If none of the applicable styles are
defined, do the right thing and don't add an invalid entry to
region_highlight.
The pattern highlighter doesn't use this function as it'd need too large
of an API change.
zsh older than workers/28418 (zsh revision 23bdfc7fd2a012d5205ed22d18eb39e41c8fbc95)
doesn't support the «${name:offset:length}» syntax. Therefore, use the older
«$name[start,end]» syntax instead.

condition; the remainder of the change gives one example of when that matters.

(corrected and refreshed for harness changes by me)
The change of behaviour is triggered by test-data/sudo-redirection.zsh: the iteration
on "otheruser" sets $next_word to ":regular::sudo_opt::start::sudo_opt::start:" before
this patch, but to ":regular::sudo_opt::start:" after it (note the deduplication).
The fix for issue #9 was accidentally broken by the penultimate commit.
Note that we don't care about aliases to ZSH_HIGHLIGHT_TOKENS_COMMANDSEPARATOR
entries, since the code deals with aliases at command position.
Use this to remove [path_prefix] highlighting during accept-* widgets.
This causes ": file.tx<CR>" to remove the underline from "file.tx", like
": file.tx<SPACE>" already does. (Assume 'file.txt' exists.)
Make the test pass by setting explicitly the global state (existing $HOME) it
depends on. Test another value of the global state (a non-existing $HOME).
All these files should be sourced, not executed; and Debian's lintian complains:
W: zsh-syntax-highlighting: script-not-executable usr/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
Fixeszsh-users/zsh-syntax-highlighting#188 in the case that both the
opening '((' and closing '))' have been typed, The case that only the
opening '((' have been typed is also fixed, but requires a zsh development
build (zsh-5.1.1-52-g4bed2cf or newer); see comments within.
Without this, redirections, history expansions, and command separators would
be matched by path_approx.
A test case is simply LBUFFER="<" RBUFFER="" (highlighted as redirection with this
fix and as path_approx without it).
Fixeszsh-users/zsh-syntax-highlighting#204.
Correct highlighting of backslash escapes within "" strings: highlight only
the four specific escape sequences defined there.

* highlighters/main/test-data/hashed-command.zsh:
Set the right region key. This makes the test more specific.
(Issue #184 would have caught this bug.)
Notably, the 'single-hyphen-option' and 'assign' contexts both default to the
'none' style, so before this patch, the tests would not have detected a failure
to apply those two contexts.
For other contexts, using $unused_highlight only helps detect the case where
the right highlight style (e.g., 'fg=yellow') is used as a result of applying
the wrong context — which should be a theoretical failure mode.
This is part of zsh-users/zsh-syntax-highlighting#198.
Fixeszsh-users/zsh-syntax-highlighting#195.
The one revision made on master between this branch's creation and merge
already uses correct offsets.
* danielsh/i195-tests-offbyone-v1:
New test for dollar-double-quoted-argument.
test harness: Fix off-by-one discrepancy between observed and expected.
'local' is a reserved word in zsh 5.1 but not in earlier versions [1].
Therefore, under zsh older than 5.1, quoting is required.
This manifested as random «builtin=''» in emitted to the terminal, and
commands (such as 'echo') highlighted as errors (in red).
[1] https://github.com/zsh-users/zsh/blob/master/README#L46
(the section "Incompatibilites between 5.0.8 and 5.1")
Given the following input:
PREBUFFER=$'echo "foo\n'
BUFFER='bar"'
This patch causes the '"foo' part to be highlighted as a string. There
is no test because the tests only check highlighting of BUFFER, and 'bar"'
is already highlighted correctly.
If one defines aliases like `++` the alias builtin tries to interprete these
as options so they have to be protected like this
alias -- ++=true
The same goes for a call to `alias` in order to expand the alias again.
This code is more lenient than bash. Examples:
$ x[y[]=
zsh: no matches found: x[y[]=
$ x[][]=
zsh: no matches found: x[][]=
The proper solution is to look inside the [...] and make sure that all
unescaped/unquoted square brackes are matched, but that is a heck of
a lot more complicated than this simple 8-character patch.
Zsh does not allow the variable name or the equals sign to be quoted or
escaped. The previous code incorrectly highlighted the following
examples as assignments:
$ 'x=y'
zsh: command not found: x=y
$ x\=y
zsh: command not found: x=y
$ "x"=y
zsh: command not found: x=y
$ \x=y
zsh: command not found: x=y
* Don't override user defined styles
* Better modularisation of highlighters
* Allow to define which highlighters are activated
* Allow to define the order in which they are defined
* Minor performance optimizations
* Fixed some variables leak
* Improve documentation
* Brackets highlighter: use ZSH_HIGHLIGHT_STYLES instead of a specific array
