## Performance improvements:
|
|
|
|
We thank Sebastian Gniazdowski and "m0viefreak" for significant contributions
|
|
in this area.
|
|
|
|
- Optimize string operations in the `main` (default) highlighter.
|
|
(#372/3cb58fd7d7b9, 02229ebd6328, ef4bfe5bcc14, #372/c6b6513ac0d6, #374/15461e7d21c3)
|
|
|
|
- Command word highlighting: Use the `zsh/parameter` module to avoid forks.
|
|
Memoize (cache) the results.
|
|
(#298, 3ce01076b521, 2f18ba64e397, 12b879caf7a6; #320, 3b67e656bff5)

|
|
|
|
|
|
## Added highlighting of:

|
|
(#248, 4f3910cbbaa5)
|
|
|
|
- Aliases that cannot be defined normally nor invoked normally (highlighted as an error).
|
|
(#263 (in part), 28932316cca6)
|
|
|
|
- Path separators (`/`) — the default behaviour remains to highlight path separators
|
|
and path components the same way.
|
|
(#136, #260, 6cd39e7c70d3, 9a934d291e7c, f3d3aaa00cc4)
|
|
|
|
- Assignments to individual positional arguments (`42=foo` to assign to `$42`).
|
|
(f4036a09cee3)
|
|
|
|
- Linewise region (the `visual-line-mode` widget, bound to `V` in zsh's `vi` keymap).
|
|
(#267, a7a7f8b42280, ee07588cfd9b)
|
|
|
|
- Command-lines recalled by `isearch` mode; requires zsh≥5.3.

(b2733a64da93)
|
|
|
|
- Mismatched `foreach`/`end` keywords.
|
|
(#96, 2bb8f0703d8f)
|
|
|
|
- In Bourne-style function definitions, when the `MULTI_FUNC_DEF` option is set
|
|
(which is the default), highlight the first word in the function body as
|
|
a command word: `f() { g "$@" }`.
|
|
(6f91850a01e1)
|
|
|
|
- `always` blocks.
|
|
(#335, e5782e4ddfb6)

|
|

|
|
(4afe670f7a1b, 44ef6e38e5a7)
|
|
|
|
- Command words from future versions of zsh (forward compatibly).
|
|
This also adds an `arg0` style that all other command word styles fall back to.
|
|
(b4537a972eed, bccc3dc26943)
|
|
|
|
- Escaped history expansions inside double quotes: `: "\!"`
|
|
(28d7056a7a06, et seq)
|
|
|
|
|
|
## Fixed highlighting of:
|
|
|
|
- Command separator tokens in syntactically-invalid positions.
|
|
(09c4114eb980)
|
|
|
|
- Redirections with a file descriptor number at command word.
|
|
(#238 (in part), 73ee7c1f6c4a)
|
|
|
|
- The `select` prompt, `$PS3`.
|
|
(#268, 451665cb2a8b)
|
|
|
|
- Values of variables in `vared`.
|
|
(e500ca246286)
|
|
|
|
- `!` as an argument (neither a history expansion nor a reserved word).
|
|

- "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)
|
|
|
|
- The non-`SHORT_LOOPS` form of `repeat` loops: `repeat 42; do true; done`.

- Lines accepted from `isearch` mode.
|
|
(#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))
|
|
|
|
- After accepting a line with the cursor on a bracket, the matching bracket
|
|
of the bracket under the cursor no longer remains highlighted (with the
|
|
`brackets` highlighter).
|
|
(4c4baede519a)
|
|
|
|
- The first word on a new line within an array assignment or initialization is no
|
|
longer considered a command position.
|
|
(8bf423d16d46)
|
|
|
|
- Subshells that end at command position, `(A=42)`, `(true;)`.
|
|
(#231, 7fb6f9979121; #344, 4fc35362ee5a)
|
|
|
|
- Command word after array assignment, `a=(lorem ipsum) pwd`.
|
|
(#330, 7fb6f9979121)
|
|
|
|
|
|
## API changes (for highlighter authors):
|
|
|
|
- New interface `_zsh_highlight_add_highlight`.
|
|
(341a3ae1f015, c346f6eb6fb6)
|
|
|
|

|
|
|
|

|
|
variable, which is in the highlighters' namespace.

|
(3e59ab41b6b8, 80148f6c8402, f91a7b885e7d)
|
|
|

|
|
|
|

|
|
|
|
- Fix warnings when `WARN_CREATE_GLOBAL` is set prior to sourcing zsh-syntax-highlighting.

|
(z-sy-h already sets `WARN_CREATE_GLOBAL` internally.)

|
|
|
|
- Warn only once, rather than once per keypress, when a highlighter is unavailable.

|
|
|
## Fixes:
