custom/plugins/zsh-syntax-highlighting/HACKING.md

+Hacking on zsh-syntax-highlighting itself
+=========================================
+
+This document includes information for people working on z-sy-h itself: on the
+core driver (`zsh-syntax-highlighting.zsh`), on the highlighters in the
+distribution, and on the test suite.  It does not target third-party
+highlighter authors (although they may find it an interesting read).
+
+The `main` highlighter
+----------------------
+
+The following function `pz` is useful when working on the `main` highlighting:
+
+```zsh
+pq() {
+  (( $#argv )) || return 0
+  print -r -l -- ${(qqqq)argv}
+}
+pz() {
+  local arg
+  for arg; do
+    pq ${(z)arg}
+  done
+}
+```
+
+It prints, for each argument, its token breakdown, similar to how the main
+loop of the `main` highlighter sees it.
+
+Testing the `brackets` highlighter
+----------------------------------
+
+Since the test harness empties `ZSH_HIGHLIGHT_STYLES` and the `brackets`
+highlighter interrogates `ZSH_HIGHLIGHT_STYLES` to determine how to highlight,
+tests must set the `bracket-level-#` keys themselves.  For example:
+
+```zsh
+ZSH_HIGHLIGHT_STYLES[bracket-level-1]=
+ZSH_HIGHLIGHT_STYLES[bracket-level-2]=
+
+BUFFER='echo ({x})'
+
+expected_region_highlight=(
+  "6  6  bracket-level-1" # (
+  "7  7  bracket-level-2" # {
+  "9  9  bracket-level-2" # }
+  "10 10 bracket-level-1" # )
+)
+```
+
+Testing the `pattern` and `regexp` highlighters
+-----------------------------------------------
+
+Because the `pattern` and `regexp` highlighters modifies `region_highlight`
+directly instead of using `_zsh_highlight_add_highlight`, the test harness
+cannot get the `ZSH_HIGHLIGHT_STYLES` keys.  Therefore, when writing tests, use
+the style itself as third word (cf. the
+[documentation for `expected_region_highlight`](docs/highlighters.md)).  For example:
+
+```zsh
+ZSH_HIGHLIGHT_PATTERNS+=('rm -rf *' 'fg=white,bold,bg=red')
+
+BUFFER='rm -rf /'
+
+expected_region_highlight=(
+  "1 8 fg=white,bold,bg=red" # rm -rf /
+)
+```
+
+Memos and commas
+----------------
+
+We append to `region_highlight` as follows:
+
+
+```zsh
+region_highlight+=("$start $end $spec, memo=zsh-syntax-highlighting")
+```
+
+That comma is required to cause zsh 5.8 and older to ignore the memo without
+ignoring the `$spec`.  It's a hack, but given that no further 5.8.x patch
+releases are planned, it's been deemed acceptable.  See issue #418 and the
+cross-referenced issues.

+
+Note that `zsh-syntax-highlighting` must be the last plugin sourced.
+
+The zsh-syntax-highlighting authors recommend manual installation over the use
+of a framework or plugin manager.
+
+This list is incomplete as there are too many
+[frameworks / plugin managers][framework-list] to list them all here.
+
+[framework-list]: https://github.com/unixorn/awesome-zsh-plugins#frameworks
+

+zsh-syntax-highlighting [![Build Status][build-status-image]][build-status-travis]
+=======================
+
+**[Fish shell][fish]-like syntax highlighting for [Zsh][zsh].**
+
+*Requirements: zsh 4.3.11+.*
+
+[fish]: http://www.fishshell.com/
+[zsh]: http://www.zsh.org/
+
+This package provides syntax highlighting for the shell zsh.  It enables
+highlighting of commands whilst they are typed at a zsh prompt into an
+interactive terminal.  This helps in reviewing commands before running
+them, particularly in catching syntax errors.
+
+Some examples:

+
+FAQ
+---
+
+### Why must `zsh-syntax-highlighting.zsh` be sourced at the end of the `.zshrc` file?
+
+zsh-syntax-highlighting works by hooking into the Zsh Line Editor (ZLE) and
+computing syntax highlighting for the command-line buffer as it stands at the
+time z-sy-h's hook is invoked.
+
+In zsh 5.2 and older,
+`zsh-syntax-highlighting.zsh` hooks into ZLE by wrapping ZLE widgets.  It must
+be sourced after all custom widgets have been created (i.e., after all `zle -N`
+calls and after running `compinit`) in order to be able to wrap all of them.
+Widgets created after z-sy-h is sourced will work, but will not update the
+syntax highlighting.
+
+In zsh newer than 5.8 (not including 5.8 itself),
+zsh-syntax-highlighting uses the `add-zle-hook-widget` facility to install
+a `zle-line-pre-redraw` hook.  Hooks are run in order of registration,
+therefore, z-sy-h must be sourced (and register its hook) after anything else
+that adds hooks that modify the command-line buffer.
+
+### Does syntax highlighting work during incremental history search?
+
+Highlighting the command line during an incremental history search (by default bound to
+to <kbd>Ctrl+R</kbd> in zsh's emacs keymap) requires zsh 5.4 or newer.
+
+Under zsh versions older than 5.4, the zsh-default [underlining][zshzle-Character-Highlighting]
+of the matched portion of the buffer remains available, but zsh-syntax-highlighting's
+additional highlighting is unavailable.  (Those versions of zsh do not provide
+enough information to allow computing the highlighting correctly.)
+
+See issues [#288][i288] and [#415][i415] for details.
+
+[zshzle-Character-Highlighting]: http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#Character-Highlighting

+zsh-syntax-highlighting / highlighters
+======================================
+
+Syntax highlighting is done by pluggable highlighters:
+
+* `main` - the base highlighter, and the only one [active by default][1].
+* `brackets` - [matches brackets][2] and parenthesis.
+* `pattern` - matches [user-defined patterns][3].
+* `cursor` - matches [the cursor position][4].
+* `root` - highlights the whole command line [if the current user is root][5].
+* `line` - applied to [the whole command line][6].
+
+[1]: highlighters/main.md
+[2]: highlighters/brackets.md
+[3]: highlighters/pattern.md
+[4]: highlighters/cursor.md
+[5]: highlighters/root.md
+[6]: highlighters/line.md
+
+
+Highlighter-independent settings
+--------------------------------
+
+By default, all command lines are highlighted.  However, it is possible to
+prevent command lines longer than a fixed number of characters from being
+highlighted by setting the variable `${ZSH_HIGHLIGHT_MAXLENGTH}` to the maximum
+length (in characters) of command lines to be highlighter.  This is useful when
+editing very long comand lines (for example, with the [`fned`][fned] utility
+function).  Example:
+
+[fned]: http://zsh.sourceforge.net/Doc/Release/User-Contributions.html#index-zed
+
+```zsh
+ZSH_HIGHLIGHT_MAXLENGTH=512
+```
+
+
+How to activate highlighters
+----------------------------
+
+To activate an highlighter, add it to the `ZSH_HIGHLIGHT_HIGHLIGHTERS` array in
+`~/.zshrc`, for example:
+
+```zsh
+ZSH_HIGHLIGHT_HIGHLIGHTERS=(main brackets pattern cursor)
+```
+
+By default, `$ZSH_HIGHLIGHT_HIGHLIGHTERS` is unset and only the `main`
+highlighter is active.
+
+
+How to tweak highlighters
+-------------------------
+
+Highlighters look up styles from the `ZSH_HIGHLIGHT_STYLES` associative array.
+Navigate into the [individual highlighters' documentation](highlighters/) to
+see what styles (keys) each highlighter defines; the syntax for values is the
+same as the syntax of "types of highlighting" of the zsh builtin
+`$zle_highlight` array, which is documented in [the `zshzle(1)` manual
+page][zshzle-Character-Highlighting].
+
+[zshzle-Character-Highlighting]: http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#Character-Highlighting
+
+Some highlighters support additional configuration parameters; see each
+highlighter's documentation for details and examples.
+
+
+How to implement a new highlighter
+----------------------------------
+
+To create your own `acme` highlighter:
+
+* Create your script at
+    `highlighters/acme/acme-highlighter.zsh`.
+
+* Implement the `_zsh_highlight_highlighter_acme_predicate` function.
+  This function must return 0 when the highlighter needs to be called and
+  non-zero otherwise, for example:
+
+    ```zsh
+    _zsh_highlight_highlighter_acme_predicate() {
+      # Call this highlighter in SVN working copies
+      [[ -d .svn ]]
+    }
+    ```
+
+* Implement the `_zsh_highlight_highlighter_acme_paint` function.
+  This function does the actual syntax highlighting, by calling
+  `_zsh_highlight_add_highlight` with the start and end of the region to
+  be highlighted and the `ZSH_HIGHLIGHT_STYLES` key to use. Define the default
+  style for that key in the highlighter script outside of any function with
+  `: ${ZSH_HIGHLIGHT_STYLES[key]:=value}`, being sure to prefix
+  the key with your highlighter name and a colon. For example:
+
+    ```zsh
+    : ${ZSH_HIGHLIGHT_STYLES[acme:aurora]:=fg=green}
+
+    _zsh_highlight_highlighter_acme_paint() {
+      # Colorize the whole buffer with the 'aurora' style
+      _zsh_highlight_add_highlight 0 $#BUFFER acme:aurora
+    }
+    ```
+
+  If you need to test which options the user has set, test `zsyh_user_options`
+  with a sensible default if the option is not present in supported zsh
+  versions. For example:
+
+    ```zsh
+    [[ ${zsyh_user_options[ignoreclosebraces]:-off} == on ]]
+    ```
+
+  The option name must be all lowercase with no underscores and not an alias.
+
+* Name your own functions and global variables `_zsh_highlight_acme_*`.
+
+    - In zsh-syntax-highlighting 0.4.0 and earlier, the entrypoints 
+        `_zsh_highlight_highlighter_acme_predicate` and
+        `_zsh_highlight_highlighter_acme_paint`
+        were named
+        `_zsh_highlight_acme_highlighter_predicate` and
+        `_zsh_highlight_highlighter_acme_paint` respectively.
+
+        These names are still supported for backwards compatibility;
+        however, support for them will be removed in a future major or minor release (v0.x.0 or v1.0.0).
+
+* Activate your highlighter in `~/.zshrc`:
+
+    ```zsh
+    ZSH_HIGHLIGHT_HIGHLIGHTERS+=(acme)
+    ```
+
+* [Write tests](../tests/README.md).

custom/plugins/zsh-syntax-highlighting/docs/highlighters/brackets.md

+zsh-syntax-highlighting / highlighters / brackets
+-------------------------------------------------
+
+This is the `brackets` highlighter, that highlights brackets and parentheses, and
+matches them.
+
+
+### How to tweak it
+
+This highlighter defines the following styles:
+
+* `bracket-error` - unmatched brackets
+* `bracket-level-N` - brackets with nest level N
+* `cursor-matchingbracket` - the matching bracket, if cursor is on a bracket
+
+To override one of those styles, change its entry in `ZSH_HIGHLIGHT_STYLES`,
+for example in `~/.zshrc`:
+
+```zsh
+# To define styles for nested brackets up to level 4
+ZSH_HIGHLIGHT_STYLES[bracket-level-1]='fg=blue,bold'
+ZSH_HIGHLIGHT_STYLES[bracket-level-2]='fg=red,bold'
+ZSH_HIGHLIGHT_STYLES[bracket-level-3]='fg=yellow,bold'
+ZSH_HIGHLIGHT_STYLES[bracket-level-4]='fg=magenta,bold'
+```
+
+The syntax for values is the same as the syntax of "types of highlighting" of
+the zsh builtin `$zle_highlight` array, which is documented in [the `zshzle(1)`
+manual page][zshzle-Character-Highlighting].

+zsh-syntax-highlighting / highlighters / cursor
+-----------------------------------------------
+
+This is the `cursor` highlighter, that highlights the cursor.
+
+
+### How to tweak it
+
+This highlighter defines the following styles:
+
+* `cursor` - the style for the current cursor position
+
+To override one of those styles, change its entry in `ZSH_HIGHLIGHT_STYLES`,
+for example in `~/.zshrc`:
+
+```zsh
+ZSH_HIGHLIGHT_STYLES[cursor]='bg=blue'
+```
+
+The syntax for values is the same as the syntax of "types of highlighting" of
+the zsh builtin `$zle_highlight` array, which is documented in [the `zshzle(1)`
+manual page][zshzle-Character-Highlighting].

+
+
+### How to tweak it
+
+This highlighter defines the following styles:
+
+* `line` - the style for the whole line

+zsh-syntax-highlighting / highlighters / pattern
+------------------------------------------------
+
+This is the `pattern` highlighter, that highlights user-defined patterns.
+
+
+### How to tweak it
+
+To use this highlighter, associate patterns with styles in the
+`ZSH_HIGHLIGHT_PATTERNS` associative array, for example in `~/.zshrc`:
+
+```zsh
+# Declare the variable
+typeset -A ZSH_HIGHLIGHT_PATTERNS
+
+# To have commands starting with `rm -rf` in red:
+ZSH_HIGHLIGHT_PATTERNS+=('rm -rf *' 'fg=white,bold,bg=red')
+```
+
+The syntax for values is the same as the syntax of "types of highlighting" of
+the zsh builtin `$zle_highlight` array, which is documented in [the `zshzle(1)`
+manual page][zshzle-Character-Highlighting].
