+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:
+
+    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_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` highlighter
+---------------------------------
+
+Because the `pattern` highlighter 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_HIGHLIGHT_PATTERNS+=('rm -rf *' 'fg=white,bold,bg=red')
+
+    BUFFER='rm -rf /'
+
+    expected_region_highlight=(
+      "1 8 fg=white,bold,bg=red" # rm -rf /
+    )
+
+Miscellany
+----------
+
+If you work on the driver (`zsh-syntax-highlighting.zsh`), you may find the following zstyle useful:

+
+
+### In your ~/.zshrc
+
+Simply clone this repository and source the script:
+
+        git clone https://github.com/zsh-users/zsh-syntax-highlighting.git
+        echo "source ${(q-)PWD}/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh" >> ${ZDOTDIR:-$HOME}/.zshrc
+
+  Then, enable syntax highlighting in the current interactive shell:
+
+        source ./zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
+
+  If `git` is not installed, download and extract a snapshot of the latest
+  development tree from:
+
+        https://github.com/zsh-users/zsh-syntax-highlighting/archive/master.tar.gz
+
+  Note the `source` command must be **at the end** of `~/.zshrc`.
+
+
+### With a plugin manager
+
+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]
+(https://github.com/unixorn/awesome-zsh-plugins#frameworks) to list them all
+here.
+
+#### [Antigen](https://github.com/zsh-users/antigen)
+
+Add `antigen bundle zsh-users/zsh-syntax-highlighting` as the last bundle in
+your `.zshrc`.
+
+#### [Oh-my-zsh](https://github.com/robbyrussell/oh-my-zsh)
+
+1. Clone this repository in oh-my-zsh's plugins directory:
+
+        git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
+
+2. Activate the plugin in `~/.zshrc`:
+
+        plugins=( [plugins...] zsh-syntax-highlighting)
+
+3. Source `~/.zshrc`  to take changes into account:
+
+        source ~/.zshrc
+
+#### [Prezto](https://github.com/sorin-ionescu/prezto)
+
+Zsh-syntax-highlighting is included with Prezto. See the [Prezto documentation]
+(https://github.com/sorin-ionescu/prezto/tree/master/modules/syntax-highlighting)
+to enable and configure highlighters.
+
+#### [zgen](https://github.com/tarjoilija/zgen)
+
+Add `zgen load zsh-users/zsh-syntax-highlighting` to the end of your `.zshrc`.
+
+#### [zplug](https://github.com/zplug/zplug)
+
+Add `zplug "zsh-users/zsh-syntax-highlighting", defer:2` to your `.zshrc`.
+
+#### [zplugin](https://github.com/psprint/zplugin)
+
+Add `zplugin load zsh-users/zsh-syntax-highlighting` to the end of your
+`.zshrc`.
+
+
+### System-wide installation
+
+Any of the above methods is suitable for a single-user installation,
+which requires no special privileges.  If, however, you desire to install
+zsh-syntax-highlighting system-wide, you may do so by running
+
+    make install
+
+and directing your users to add
+
+    source /usr/local/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
+
+to their `.zshrc`s.

+This package provides syntax highlighing for the shell zsh.  It enables
+highlighing 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:

-
-        source ~/.zshrc

-### With oh-my-zsh
+FAQ
+---
 
-* Download the script or clone this repository in [oh-my-zsh](http://github.com/robbyrussell/oh-my-zsh) plugins directory:
+### Why must `zsh-syntax-highlighting.zsh` be sourced at the end of the `.zshrc` file?
 
-        cd ~/.oh-my-zsh/custom/plugins
-        git clone git://github.com/zsh-users/zsh-syntax-highlighting.git
+`zsh-syntax-highlighting.zsh` wraps ZLE widgets.  It must be sourced after all
+custom widgets have been created (i.e., after all `zle -N` calls and after
+running `compinit`).  Widgets created later will work, but will not update the
+syntax highlighting.
 
-* Activate the plugin in `~/.zshrc` (in **last** position):
+### Does syntax highlighting work during incremental history search?
 
-        plugins=( [plugins...] zsh-syntax-highlighting)
+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.
 
-* Source `~/.zshrc`  to take changes into account:
-    
-        source ~/.zshrc
+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.

+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
+
+
+How to activate highlighters
+----------------------------
+
+To activate an highlighter, add it to the `ZSH_HIGHLIGHT_HIGHLIGHTERS` array in
+`~/.zshrc`, for example:
+
+    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_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_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
+        }
+
+* 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 a future major or minor release (v0.x.0 or v1.0.0).
+
+* Activate your highlighter in `~/.zshrc`:
+
+        ZSH_HIGHLIGHT_HIGHLIGHTERS+=(acme)
+
+* [Write tests](../tests/README.md).

+manual page][zshzle-Character-Highlighting].
+
+### Useless trivia
+
+#### Forward compatibility.
+
+zsh-syntax-highlighting attempts to be forward-compatible with zsh.
+Specifically, we attempt to facilitate highlighting _command word_ types that
+had not yet been invented when this version of zsh-syntax-highlighting was
+released.
+
+A _command word_ is something like a function name, external command name, et
+cetera.  (See
+[Simple Commands & Pipelines in `zshmisc(1)`][zshmisc-Simple-Commands-And-Pipelines]
+for a formal definition.)
+
+If a new _kind_ of command word is ever added to zsh — something conceptually
+different than "function" and "alias" and "external command" — then command words
+of that (new) kind will be highlighted by the style `arg0_$kind`,
+where `$kind` is the output of `type -w` on the new kind of command word.  If that
+style is not defined, then the style `arg0` will be used instead.

 zsh-syntax-highlighting / highlighters
 ======================================
 
-Syntax highlighting is done by pluggable highlighters:
+Navigate into the individual highlighters' documentation to see
+what styles (`$ZSH_HIGHLIGHT_STYLES` keys) each highlighter defines.
 
-* [***main***](highlighters/main) - the base highlighter, and the only one active by default.
-* [***brackets***](highlighters/brackets) - matches brackets and parenthesis.
-* [***pattern***](highlighters/pattern) - matches user-defined patterns.
-* [***cursor***](highlighters/cursor) - matches the cursor position.
-* [***root***](highlighters/root) - triggered if the current user is root.
-
-
-How to activate highlighters
-----------------------------
-
-To activate an highlighter, add it to the `ZSH_HIGHLIGHT_HIGHLIGHTERS` array in `~/.zshrc`, for example:
-
-    ZSH_HIGHLIGHT_HIGHLIGHTERS=(main brackets pattern cursor)
-
-
-How to tweak highlighters
--------------------------
-
-Highlighters look up styles from the `ZSH_HIGHLIGHT_STYLES` array. Navigate into each highlighter directory to see what styles it defines and how to configure it.
-
-
-How to implement a new highlighter
-----------------------------------
-
-To create your own ***myhighlighter*** highlighter:
-
-* Create your script at **highlighters/*myhighlighter*/*myhighlighter*-highlighter.zsh**.
-* Implement the `_zsh_highlight_myhighlighter_highlighter_predicate` function. This function must return 0 when the highlighter needs to be called, for example:
-
-        _zsh_highlight_myhighlighter_highlighter_predicate() {
-          # Call this highlighter in SVN repositories
-          [[ -d .svn ]]
-        }
-
-* Implement the `_zsh_highlight_myhighlighter_highlighter` function. This function does the actual syntax highlighting, by modifying `region_highlight`, for example:
-
-        _zsh_highlight_myhighlighter_highlighter() {
-          # Colorize the whole buffer with blue background
-          region_highlight+=(0 $#BUFFER bg=blue)
-        }
-
-* Activate your highlighter in `~/.zshrc`:
-
-        ZSH_HIGHLIGHT_HIGHLIGHTERS+=(myhighlighter)
+Refer to the [documentation on highlighters](../docs/highlighters.md) for further
+information.

-zsh-syntax-highlighting / highlighters / brackets
-=================================================
-
-This is the ***brackets*** highlighter, that highlights brackets, parenthesis and matches them.
-
-
-How to activate it
-------------------
-To activate it, add it to `ZSH_HIGHLIGHT_HIGHLIGHTERS`:
-
-    ZSH_HIGHLIGHT_HIGHLIGHTERS=( [...] brackets)
-
-
-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`:
-
-    # 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 declaring styles is [documented here](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#SEC135).

-
-
-How to tweak it
----------------
-This highlighter defines the following styles:
-

-
-To override one of those styles, change its entry in `ZSH_HIGHLIGHT_STYLES`, for example in `~/.zshrc`:
-
-    ZSH_HIGHLIGHT_STYLES[cursor]='bg=blue'
-
-The syntax for declaring styles is [documented here](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#SEC135).

-=============================================
-
-This is the ***main*** highlighter, that highlights:
-
-* Commands
-* Options
-* Arguments
-* Paths
-* Strings
-
-How to activate it
-------------------
-To activate it, add it to `ZSH_HIGHLIGHT_HIGHLIGHTERS`:
-
-    ZSH_HIGHLIGHT_HIGHLIGHTERS=( [...] main)
-
-This highlighter is active by default.
-
-
-How to tweak it
----------------
-This highlighter defines the following styles:
-
-* `unknown-token` - unknown tokens / errors
-* `reserved-word` - shell reserved words
-* `alias` - aliases
-* `builtin` - shell builtin commands
-* `function` - functions
-* `command` - commands
-* `precommand` - precommands (i.e. exec, builtin, ...)
-* `commandseparator` - command separation tokens
-* `hashed-command` - hashed commands
-* `path` - paths
-* `globbing` - globbing expressions
-* `history-expansion` - history expansion expressions
-* `single-hyphen-option` - single hyphen options
-* `double-hyphen-option` - double hyphen options
-* `back-quoted-argument` - backquoted expressions
-* `single-quoted-argument` - single quoted arguments
-* `double-quoted-argument` - double quoted arguments
-* `dollar-double-quoted-argument` -  dollar double quoted arguments
-* `back-double-quoted-argument` -  back double quoted arguments
-* `assign` - variable assignments
-* `default` - parts of the buffer that do not match anything
-
-To override one of those styles, change its entry in `ZSH_HIGHLIGHT_STYLES`, for example in `~/.zshrc`:
-
-    # To differentiate aliases from other command types
-    ZSH_HIGHLIGHT_STYLES[alias]='fg=magenta,bold'
-    
-    # To have paths colored instead of underlined
-    ZSH_HIGHLIGHT_STYLES[path]='fg=cyan'
-    
-    # To disable highlighting of globbing expressions
-    ZSH_HIGHLIGHT_STYLES[globbing]='none'
-
-The syntax for declaring styles is [documented here](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#SEC135).
