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, 02229ebd63, ef4bfe5bcc, #372/c6b6513ac0d6, #374/15461e7d21c3)

  • Command word highlighting: Use the zsh/parameter module to avoid forks. Memoize (cache) the results. (#298, 3ce01076b5, 2f18ba64e3, 12b879caf7a6; #320, 3b67e656bf)

  • Avoid forks in the driver and in the root highlighter. (b9112aec79, 38c8fbea2d)

Added highlighting of:

  • pkexec (a precommand). (#248, 4f3910cbba)

  • Aliases that cannot be defined normally nor invoked normally (highlighted as an error). (#263 (in part), 28932316cc)

  • Path separators (/) — the default behaviour remains to highlight path separators and path components the same way. (#136, #260, 6cd39e7c70, 9a934d291e, f3d3aaa00c)

  • Assignments to individual positional arguments (42=foo to assign to $42). (f4036a09ce)

  • Linewise region (the visual-line-mode widget, bound to V in zsh's vi keymap). (#267, a7a7f8b422, ee07588cfd)

  • Command-lines recalled by isearch mode; requires zsh≥5.3. (#261 (in part); #257; 4ad311ec0a)

  • Command-lines whilst the IGNORE_BRACES or IGNORE_CLOSE_BRACES option is in effect. (a8a6384356, 02807f1826)

  • Mismatched parentheses and braces (in the main highlighter). (51b9d79c3b, 2fabf7ca64, a4196eda5e, and others)

  • Mismatched do/done keywords. (b2733a64da)

  • Mismatched foreach/end keywords. (#96, 2bb8f0703d)

  • 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 "$@" }. (6f91850a01)

  • always blocks. (#335, e5782e4ddf)

  • Command substitutions inside double quotes, "$(echo foo)". (#139 (in part), c3913e0d8e)

  • Non-alphabetic parameters inside double quotes ("$$", "$#", "$*", "$@", "$?", "$-"). (4afe670f7a, 44ef6e38e5)

  • Command words from future versions of zsh (forward compatibly). This also adds an arg0 style that all other command word styles fall back to. (b4537a972e, bccc3dc269)

  • Escaped history expansions inside double quotes: : "\!" (28d7056a7a, et seq)

Fixed highlighting of:

  • Command separator tokens in syntactically-invalid positions. (09c4114eb9)

  • Redirections with a file descriptor number at command word. (#238 (in part), 73ee7c1f6c)

  • The select prompt, $PS3. (#268, 451665cb2a)

  • Values of variables in vared. (e500ca2462)

  • ! as an argument (neither a history expansion nor a reserved word). (4c23a2fd1b)

  • "division by zero" error under the brackets highlighter when $ZSH_HIGHLIGHT_STYLES is empty. (f73f3d53d3)

  • Process substitutions, <(pwd) and >(wc -l). (#302, 6889ff6bd2, bfabffbf97, fc9c892a3f)

  • The non-SHORT_LOOPS form of repeat loops: repeat 42; do true; done. (#290, 4832f18c50, ef68f50c04, 6362c757b6)

  • Broken symlinks (are now highlighted as files). (#342, 95f7206a93, 53083da821)

  • Lines accepted from isearch mode. (#284; #257, #259, #288; 5bae621900, a8fe22d422)

  • 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, 51614ca2c9, fdaeec4514, 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). (4c4baede51)

  • The first word on a new line within an array assignment or initialization is no longer considered a command position. (8bf423d16d)

  • Subshells that end at command position, (A=42), (true;). (#231, 7fb6f9979121; #344, 4fc35362ee)

  • Command word after array assignment, a=(lorem ipsum) pwd. (#330, 7fb6f99791)

API changes (for highlighter authors):

Developer-visible changes:

Other changes:

  • Under zsh≤5.2, widgets whose names start with a _ are no longer excluded from highlighting. (ed33d2cb1388; reverts part of 186d80054a 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 776453cb5b)

  • Under zsh≤5.2, shell-unsafe widget names can now be wrapped. (#278, 6a634fac9f, et seq)

  • Correct some test expectations. (78290e043b)

  • zsh-syntax-highlighting.plugin.zsh: Convert from symlink to plain file for msys2 compatibility. (#292, d4f8edc9f3)

  • Document installation under some plugin managers. (e635f766be, 9cab566f53)

  • Don't leak the PATH_DIRS option. (7b82b88a71)

  • Don't require the FUNCTION_ARGZERO option to be set. (#338, 750aebc553)

  • Under zsh≤5.2, support binding incomplete/nonexistent widgets. (9e569bb0fe, part of #288)

  • Make the driver reentrant, fixing possibility of infinite recursion under zsh≤5.2 under interaction with theoretical third-party code. (#305, d711563fe1, 295d62ec88, f3242cbd6a)

  • Fix warnings when WARN_CREATE_GLOBAL is set prior to sourcing zsh-syntax-highlighting. (z-sy-h already sets WARN_CREATE_GLOBAL internally.) (da60234fb2)

  • Warn only once, rather than once per keypress, when a highlighter is unavailable. (0a9b347483)

Changes in version 0.5.0

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 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.

    (#90, part of #245, XXXXXXXXXXXX)

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}). (282c7134e8, reverts c808d2187a)

Changes in version 0.4.0

Added highlighting of:

  • incomplete sudo commands (a3047a9121, 2f05620b19)

      sudo;
  sudo -u;

  • command words following reserved words (#207, #222, b397b12ac1 et seq, 6fbd2aa957 et seq, 8b4adbd991)

      if ls; then ls; else ls; fi
  repeat 10 do ls; done

    (The ls are now highlighted as a command.)

  • comments (when INTERACTIVE_COMMENTS is set) (#163, #167, 693de99a90)

      echo Hello # comment

  • closing brackets of arithmetic expansion, subshells, and blocks (#226, a59f442d2d, et seq)

      (( foo ))
  ( foo )
  { foo }

  • command names enabled by the PATH_DIRS option (#228, 96ee5116b1)

      # When ~/bin/foo/bar exists, is executable, ~/bin is in $PATH,
  # and 'setopt PATH_DIRS' is in effect
  foo/bar

  • parameter expansions with braces inside double quotes (#186, 6e3720f39d)

      echo "${foo}"

  • parameter expansions in command word (#101, 4fcfb15913)

      x=/bin/ls
  $x -l

  • the command separators '|&', '&!', '&|'

      view file.pdf &!  ls

Fixed highlighting of:

  • precommand modifiers at non-command-word position (#209, 2c9f8c8c95)

      ls command foo

  • sudo commands with infix redirections (#221, be006aded5, 86e9249709)

      sudo -u >/tmp/foo.out user ls

  • subshells; anonymous functions (#166, #194, 0d1bfbcbfa, 9e178f9f39)

      (true)
  () { true }

  • parameter assignment statements with no command (#205, 01d7eeb3c7)

      A=1;

    (The semicolon used to be highlighted as a mistake)

  • cursor highlighter: Remove the cursor highlighting when accepting a line. (#109, 4f0c293fde)

Removed features:

  • Removed highlighting of approximate paths (path_approx). (#187, 98aee7f8b9)

Other changes:

  • main highlighter refactored to use states rather than booleans. (2080a441ac, et seq)

  • Fix initialization when sourcing zsh-syntax-highlighting.zsh via a symlink (083c47b007)

  • docs: Add screenshot. (57624bb9f6)

  • widgets wrapping: Don't add '--' when invoking widgets. (c808d2187a) [reverted in 0.4.1]

  • Refresh highlighting upon accept-* widgets (accept-line et al). (59fbdda64c)

  • Stop leaking match/mbegin/mend to global scope (thanks to upstream WARN_CREATE_GLOBAL improvements). (d3deffbf46)

  • 'make install': Permit setting $(SHARE_DIR) from the environment. (e1078a8b4c)
