# Changes in version 0.5.0
## 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)
- Avoid forks in the driver and in the `root` highlighter.
(b9112aec798a, 38c8fbea2dd2)
## Added highlighting of:
- `pkexec` (a precommand).
(#248, 4f3910cbbaa5)
- Aliases that cannot be defined normally nor invoked normally (highlighted as an error).
(#263 (in part), 28932316cca6)
- The `isearch` and `suffix` [`$zle_highlight` settings][zshzle-Character-Highlighting].
(79e4d3d12405, 15db71abd0cc; requires zsh 5.3 for `$ISEARCHMATCH_ACTIVE` / `$SUFFIX_ACTIVE` support)
[zshzle-Character-Highlighting]: http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#Character-Highlighting
- 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 `$42`).
(f4036a09cee3)
- Linewise region (the `visual-line-mode` widget, bound to `V` in zsh's `vi` keymap).
(#267, a7a7f8b42280, ee07588cfd9b)
- Command-lines recalled by `isearch` mode; requires zsh≥5.3.
(#261 (in part); #257; 4ad311ec0a68)
- Command-lines whilst the `IGNORE_BRACES` or `IGNORE_CLOSE_BRACES` option is in effect.
(a8a6384356af, 02807f1826a5)
- Mismatched parentheses and braces (in the `main` highlighter).
(51b9d79c3bb6, 2fabf7ca64b7, a4196eda5e6f, and others)
- Mismatched `do`/`done` keywords.
(b2733a64da93)
- Mismatched `foreach`/`end` keywords.
(#96, 2bb8f0703d8f)
- In Bourne-style function definitions, when the `MULTI_FUNC_DEF` option is set
(which is the default), highlight the first word in the function body as
a command word: `f() { g "$@" }`.
(6f91850a01e1)
- `always` blocks.
(#335, e5782e4ddfb6)
- Command substitutions inside double quotes, `"$(echo foo)"`.
(#139 (in part), c3913e0d8ead)
- Non-alphabetic parameters inside double quotes (`"$$"`, `"$#"`, `"$*"`, `"$@"`, `"$?"`, `"$-"`).
(4afe670f7a1b, 44ef6e38e5a7)
- Command words from future versions of zsh (forward compatibly).
This also adds an `arg0` style that all other command word styles fall back to.
(b4537a972eed, bccc3dc26943)
- Escaped history expansions inside double quotes: `: "\!"`
(28d7056a7a06)
## Fixed highlighting of:
- Command separator tokens in syntactically-invalid positions.
(09c4114eb980)
- Redirections with a file descriptor number at command word.
(#238 (in part), 73ee7c1f6c4a)
- The `select` prompt, `$PS3`.
(#268, 451665cb2a8b)
- Values of variables in `vared`.
(e500ca246286)
- `!` as an argument (neither a history expansion nor a reserved word).
(4c23a2fd1b90)
- "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`.
(#290, 4832f18c50a5, ef68f50c048f, 6362c757b6f7)
- Broken symlinks (are now highlighted as files).
(#342, 95f7206a9373, 53083da8215e)
- 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 $PATH directory denoted a command;
the effect of that upstream bug was that the relative path was cached as
a "valid external command name".
(#354, #355, 51614ca2c994, fdaeec45146b, 7d38d07255e4;
upstream fix slated to be released in 5.3 (workers/39104))
- After accepting a line with the cursor on a bracket, the matching bracket
of the bracket under the cursor no longer remains highlighted (with the
`brackets` highlighter).
(4c4baede519a)
- The first word on a new line within an array assignment or initialization is no
longer considered a command position.
(8bf423d16d46)
- Subshells that end at command position, `(A=42)`, `(true;)`.
(#231, 7fb6f9979121; #344, 4fc35362ee5a)
- Command word after array assignment, `a=(lorem ipsum) pwd`.
(#330, 7fb6f9979121)
## API changes (for highlighter authors):
- New interface `_zsh_highlight_add_highlight`.
(341a3ae1f015, c346f6eb6fb6)
- tests: Specify the style key, not its value, in test expectations.
(a830613467af, fd061b5730bf, eaa4335c3441, among others)
- Module author documentation improvements.
(#306 (in part), 217669270418, 0ff354b44b6e, 80148f6c8402, 364f206a547f, and others)
- The driver no longer defines a `_zsh_highlight_${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: Add the "NONE" expectation.
(4da9889d1545, 13018f3dd735, d37c55c788cd)
- tests: consider a test that writes to stderr to have failed.
(#291, 1082067f9315)
## Developer-visible changes:
- Add `make quiet-test`.
(9b64ad750f35)
- test harness: Better quote replaceables in error messages.
(30d8f92df225)
- test harness: Fix exit code for XPASS.
(bb8d325c0cbd)
- Create [HACKING.md](HACKING.md).
(cef49752fd0e)
- tests: Emit a description for PASS test points.
(6aa57d60aa64, f0bae44b76dd)
- 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)
- Under zsh≤5.2, widgets implemented by a function named after the widget are
no longer excluded from highlighting.
(487b122c480d; reverts part of 776453cb5b69)
- Under zsh≤5.2, shell-unsafe widget names can now be wrapped.
(#278, 6a634fac9fb9, et seq)
- Correct some test expectations.
(78290e043bc5)
- `zsh-syntax-highlighting.plugin.zsh`: Convert from symlink to plain file
for msys2 compatibility.
(#292, d4f8edc9f3ad)
- Document installation under some plugin managers.
(e635f766bef9, 9cab566f539b)
- Don't leak the `PATH_DIRS` option.
(7b82b88a7166)
- Don't require the `FUNCTION_ARGZERO` option to be set.
(#338, 750aebc553f2)
- Under zsh≤5.2, support binding incomplete/nonexistent widgets.
(9e569bb0fe04, part of #288)
- Make the driver reentrant, fixing possibility of infinite recursion
under zsh≤5.2 under interaction with theoretical third-party code.
(#305, d711563fe1bf, 295d62ec888d, f3242cbd6aba)
- Fix warnings when `WARN_CREATE_GLOBAL` is set prior to sourcing zsh-syntax-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 0.4.1
## Fixes:
- Arguments to widgets were not properly dash-escaped. Only matters for widgets
that take arguments (i.e., that are invoked as `zle ${widget} -- ${args}`).

# and 'setopt PATH_DIRS' is in effect
foo/bar
- parameter expansions with braces inside double quotes
(#186, 6e3720f39d84)

- Refresh highlighting upon `accept-*` widgets (`accept-line` et al).
(59fbdda64c21)
