Changes in HEAD
Changes fixed as part of the switch to zle-line-pre-redraw
The changes in this section were fixed by switching to a zle-line-pre-redraw
-based
implementation.
Note: The new implementation will only be used on future zsh releases, numbered 5.8.0.3 and newer, due to interoperability issues with other plugins (issues #418 and #579). The underlying zsh feature has been available since zsh 5.2.
Whilst under development, the new implementation was known as the "feature/redrawhook" topic branch.
-
Fixed: Highlighting not triggered after popping a buffer from the buffer stack (using the
push-line
widget, default binding:M-q
) [#40] -
Fixed: Invoking completion when there were no matches removed highlighting [#90, #470]
-
Fixed: Two successive deletes followed by a yank only yanked the latest delete, rather than both of them [#150, #151, #160; cf. #183]
-
Presumed fixed: Completing
$(xsel)
results in an error message fromxsel
, with pre-2017 versions ofxsel
. (For 2017 vintage and newer, see the issue for details.) [#154] -
Fixed: When the standard
bracketed-paste-magic
widget is in use, pastes were slow [#295] -
Fixed: No way to prevent a widget from being wrapped [#324]
-
Fixed: No highlighting while cycling menu completion [#375]
-
Fixed: Does not coexist with the
IGNORE_EOF
option [#377] -
Fixed: The
undefined-key
widget was wrapped [#421] -
Fixed: Does not coexist with the standard
surround
family of widgets [#520] -

path
highlighting [#632]

Changes in 0.8.0-alpha1-pre-redrawhook
Notice about an improbable-but-not-impossible forward incompatibility
Everyone can probably skip this section.
The master
branch of zsh-syntax-highlighting uses a zsh feature that has not
yet appeared in a zsh release: the memo=
feature, added to zsh in commit
zsh-5.8-172-gdd6e702ee (after zsh 5.8, before zsh 5.9). In the unlikely event
that this zsh feature should change in an incompatible way before the next
stable zsh release, set zsh_highlight__memo_feature=0
in your .zshrc files to
disable use of the new feature.
z-sy-h dogfoods the new, unreleased zsh feature because that feature was added to zsh at z-sy-h's initiative. The new feature is used in the fix to issue #418.
Incompatible changes:
-
An unsuccessful completion (a ⮀ Tab press that doesn't change the command line) no longer causes highlighting to be lost. Visual feedback can alternatively be achieved by setting the
format
zstyle under thewarnings
tag, for example,zstyle ':completion:*:warnings' format '%F{red}No matches%f'
Refer to the [description of the
format
style inzshcompsys(1)
] zshcompsys-Standard-Styles-format.(#90, part of #245 (feature/redrawhook))
