# Changes in HEAD
- Highlight `&>` `>&|` `>&!` `&>|` and `&>!` as redirection.
[#942]
# Changes in 0.8.0
This is a stable bugfix and feature release. Major new features and changes include:
## 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 5.8.1.1 and newer, due to interoperability issues with other plugins
(issues #418 and #579). The underlying zsh feature has been available since
zsh 5.3.
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 from `xsel`,
with pre-2017 versions of `xsel`. (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]
- Fixed: First completed filename doesn't get `path` highlighting
[#632]
## Other changes
- Add issue #712 to the previous release's changelog (hereinafter).
- Fix highlighting when using an alias twice inside another alias
[#769, #775]
- Remove lint warning for `env` followed by a pipe
[#797]
- Recognize `proxychains` as a precommand
[#814, #914]
- Honor shwordsplit when expanding parameters
[#687, #818]
- Skip highlighting when keys are still pending in more cases
[#835]
- Recognize `grc` as a precommand
- Recognize `torsocks` and `torift` as precommands
[#898]
- Recognize `cpulimit` as a precommand
[#897]
- Recognize `ktrace` as a precommand
# 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 <kbd>⮀ Tab</kbd> 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 the `warnings`
tag, for example,
zstyle ':completion:*:warnings' format '%F{red}No matches%f'
Refer to the [description of the `format` style in `zshcompsys(1)`]
[zshcompsys-Standard-Styles-format].

[#698]

[#730]

[#622, #689]
- Literal semicolons in array assignments (`foo=( bar ; baz )`) are now
highlighted as errors.
[3ca93f864fb6]
- Command separators in array assignments (`foo=( bar | baz )`) are now
highlighted as errors.
[#651, 81267ca3130c]
- Support parameter elision in command position (e.g., `$foo ls` where `$foo` is unset or empty)
[#667]
- Don't consider the filename in `sudo -e /path/to/file` to be a command position
[#678]
- Don't look up absolute directory names in $cdpath
[2cc2583f8f12, part of #669]
- Fix `exec 2>&1;` being highlighted as an error.
[#676]

- Highlight global aliases

[#669]
- Recognize `env` as a precommand (e.g., `env FOO=bar ls`)

[#727, #731, #732, #733]

requires zsh 5.8.0.3 or newer. (zsh 5.8.0.2-dev from the `master` branch,
revision zsh-5.8-172-gdd6e702ee or newer is also fine.)
[#418, https://github.com/okapia/zsh-viexchange/issues/1]
- Improve performance of the `brackets` highlighter.
- Fix highlighting of pre-command redirections (e.g., the `$fn` in `<$fn cat`)

- Aliases that cannot be defined normally nor invoked normally (highlighted as an error).

and path components the same way.

- Assignments to individual positional arguments (`42=foo` to assign to `$42`).

(b2733a64da93)
- Mismatched `foreach`/`end` keywords.
(#96, 2bb8f0703d8f)

- Escaped history expansions inside double quotes: `: "\!"`
(28d7056a7a06, et seq)
## Fixed highlighting of:

- "division by zero" error under the `brackets` highlighter when `$ZSH_HIGHLIGHT_STYLES` is empty.
(f73f3d53d3a6)
- Process substitutions, `<(pwd)` and `>(wc -l)`.
(#302, 6889ff6bd2ad, bfabffbf975c, fc9c892a3f15)

(#284; #257, #259, #288; 5bae6219008b, a8fe22d42251)
- Work around upstream bug that triggered when the command word was a relative
path, that when interpreted relative to a $PATH directory denoted a command;
the effect of that upstream bug was that the relative path was cached as
a "valid external command name".
(#354, #355, 51614ca2c994, fdaeec45146b, 7d38d07255e4;
upstream fix slated to be released in 5.3 (workers/39104))

longer considered a command position.

- The driver no longer defines a `_zsh_highlight_${highlighter}_highlighter_cache`
variable, which is in the highlighters' namespace.
(3e59ab41b6b8, 80148f6c8402, f91a7b885e7d)
- Rename highlighter entry points. The old names remain supported for
backwards compatibility.
(a3d5dfcbdae9, c793e0dceab1)

- tests: Create a script that generates a test file.
(8013dc3b8db6, et seq; `tests/generate.zsh`)
## Other changes:
- Under zsh≤5.2, widgets whose names start with a `_` are no longer excluded
from highlighting.
(ed33d2cb1388; reverts part of 186d80054a40 which was for #65)

no longer excluded from highlighting.

(z-sy-h already sets `WARN_CREATE_GLOBAL` internally.)
(da60234fb236)
- Warn only once, rather than once per keypress, when a highlighter is unavailable.
(0a9b347483ae)

# Changes in version 0.3.0
## Added highlighting of:
- suffix aliases (requires zsh 5.1.1 or newer):
```zsh
alias -s png=display
foo.png
```
- prefix redirections:
```zsh
<foo.txt cat
```
- redirection operators:
```zsh
echo > foo.txt
```
- arithmetic evaluations:
```zsh
(( 42 ))
```
- $'' strings, including \x/\octal/\u/\U escapes
```zsh
: $'foo\u0040bar'
```
- multiline strings:
```zsh
% echo "line 1
line 2"
```
- string literals that haven't been finished:
```zsh
% echo "Hello, world
```
- command words that involve tilde expansion:
```zsh
% ~/bin/foo
```
## Fixed highlighting of:
- quoted command words:
```zsh
% \ls
```
- backslash escapes in "" strings:
```zsh
% echo "\x41"
```
- noglob after command separator:
```zsh
% :; noglob echo *
```
- glob after command separator, when the first command starts with 'noglob':
```zsh
% noglob true; echo *
```
- the region (vi visual mode / set-mark-command) (issue #165)
- redirection and command separators that would be highlighted as `path_approx`
```zsh
% echo foo;‸
% echo <
```
(where `‸` represents the cursor location)
- escaped globbing (outside quotes)
```zsh
% echo \*
```
## Other changes:
- implemented compatibility with zsh's paste highlighting (issue #175)
- `$?` propagated correctly to wrapped widgets
- don't leak $REPLY into global scope
## Developer-visible changes:
- added makefile with `install` and `test` targets
- set `warn_create_global` internally
- document release process
