- Extract duplicated code into a new function.
This makes it easier to add support for other entries in the
future, that cannot be accessed in the current version of zsh
(isearch, suffix).
- Make decision logic more comprehensible.
- Respect deliberately empty entries in zle_highlight.
Don't force the default value when the user deliberately sets
an entry in zle_highlight to the empty string.
For example
zle_highligh(paste:)
to disable paste highlighting completely.
Skipping when $cur_widgets == user:$cur_widget was introduced
with 776453cb5b. However there
are cases where this is not just an 'already rebound' event, but
simply a normal widget whose function name happens to be identical
to its widget name.
Example:
expand-absolute-path is a widget whose function name is also
expand-absolute-path. No reason why this should be ignored.
Another example:
edit-command-line
./parse.zsh "zplugin.zsh" > out_norm.txt 106,17s user 7,84s system 98% cpu 1:55,85 total
./parse.zsh "zplugin.zsh" > out_opt.txt 51,91s user 7,44s system 99% cpu 59,912 total
% wc -l zplugin.zsh
3188 zplugin.zsh
The '--' guard was correct; it was there to guard against arguments belonging
to the syntax «zle widget [ -n num ] [ -Nw ] [ -K keymap ] args».
For example, this affected using <backward-kill-word> over
BUFFER="-w "
CURSOR=3
after
autoload -Uz select-word-style
select-word-style default
zstyle ':zle:backward-kill-word' word-style shell
.
This reverts commit c808d2187a.
Fixeszsh-users/zsh-syntax-highlighting#262.
Currently, 'make quiet-test' uses Perl. However, since it is considered a development
tool rather than a user-facing tool, users and downstream packages needn't install Perl.
Furthermore, even this dev-only dependency may be dropped in the future.
The only difference between tests/tap-filter here and the one in the issue is using
a `cat` subshell v. using 'undef $/; <STDIN>'.
Just because a widget starts with _ does not mean it should be
skipped when rebinding. The only reason widgets need to be skipped
is when their function name start with _zsh_highlight_widget*,
which is checked later.
Example:
_expand_alias (^Xa) needs to be wrapped.
The exclusion of _* was introduced in 186d80054a
to fix#65, but it is not needed. The relevant exclusion of
_zsh_highlight_widget* is already enough due to the case statement.
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.
