1. OVERVIEW
-------------------------------------------------------------------------------

Highlight converts sourcecode to HTML, XHTML, RTF, ODT, LaTeX, TeX, SVG, BBCode, 
Pango markup and terminal escape sequences with coloured syntax highlighting.
Language definitions and colour themes are customizable.


1.1 INTENDED PURPOSE
-------------------------------------------------------------------------------

Highlight was designed to offer a flexible but easy to use syntax highlighter
for several output formats. No syntax or colouring information is hardcoded,
instead all relevant data is stored in configuration scripts. These Lua scripts
may be altered or enhanced with plug-in scripts.


1.2 FEATURE LIST
-------------------------------------------------------------------------------

* highlighting of keywords, types, strings, numbers, escape sequences, comments,
  operators and preprocessor directives
* coloured output in HTML, XHTML 1.1, RTF, TeX, LaTeX, SVG, BBCode, Pango Markup 
  and terminal escape sequences
* supports referenced stylesheet files for HTML, LaTeX, TeX or SVG output
* configuration files are Lua scripts
* supports plug-in scripts to tweak language definitions and themes
* syntax elements are defined as regular expressions or plain string lists
* customizable keyword groups
* recognition of nested languages within a file
* reformatting and indentation of C, C++, C# and Java source code
* wrapping of long lines
* configurable output of line numbers


1.3 SUPPORTED PROGRAMMING AND MARKUP LANGUAGES
-------------------------------------------------------------------------------

Please see README_LANGLIST for the current set of supported languages.
You may also run "highlight --list-scripts=langs" to get a list and associated
file extensions.


2. USAGE AND OPTIONS
-------------------------------------------------------------------------------

2.1 QUICK INTRODUCTION
-------------------------------------------------------------------------------

The following examples show how to produce a highlighted C++ file, using 
main.cpp as input file:

- Generate HTML:
  highlight -i main.cpp -o main.cpp.html
  highlight < main.cpp > main.cpp.html --syntax cpp

  You will find the HTML file and highlight.css in the working directory.
  If you use IO redirection (see 2nd example), you must define the programming
  language using --syntax.

- Generate HTML with embedded CSS definitions and line numbers:
  highlight -i main.cpp -o main.cpp.html --include-style --line-numbers

- Generate HTML with inline CSS definitions:
  highlight -i main.cpp -o main.cpp.html --inline-css

- Generate HTML using "horstmann" source formatting style and "neon" colour
  theme:
  highlight -i main.cpp -o main.cpp.html --reformat horstmann --style neon

- Generate LaTeX:
  highlight --out-format=latex -i main.cpp -o main.cpp.tex

  The following output formats may be defined with --out-format:
  html:     HTML5
  xhtml:    XHTML 1.1
  tex:      Plain TeX
  latex:    LaTeX
  rtf:      RTF
  odt:      OpenDocument Text (Flat XML)
  svg:      SVG
  bbcode:   BBCode
  pango:    Pango markup
  ansi:     Terminal 16 color escape codes
  xterm256: Terminal 256 color escape codes

  Default output is HTML if no other format is specified.

- Customize font settings:
  highlight --syntax ada --font-size 12 --font "'Courier New',monospace"
  highlight --syntax ada --out-format=latex --font-size tiny --font sffamily

- Define an output directory:
  highlight -d some/target/dir/ *.cpp *.h

See "highlight --help" or "man highlight" for more details.

2.3 GUI OPTIONS
-------------------------------------------------------------------------------

The Graphical User Interface offers a subset of the CLI's features. It includes
a dynamic preview of the output file's apperarance. Please see screenshots and
screencasts on the project website.
Invoke highlight-gui with the --portable option to let it save its settings
in the binary's current directory (instead of using the registry).


2.4 INPUT AND OUTPUT
-------------------------------------------------------------------------------

If no input or output file name is defined by --input and --output options,
highlight will use stdin and stdout for file processing.

If no input filename is defined by --input or given at the prompt, highlight is
not able to determine the language type by means of the file extension (except
some scripting languages which are figured out by the shebang in the first input
line). In this case you have to pass highlight the given langage with --syntax
(this should be the file suffix of the source file in most cases).
Example: If you want to convert a Python file, highlight needs to load the
py.lang language definition. The correct argument of --syntax would be "py".

highlight test.py
highlight < test.py --syntax py       # --syntax option necessary
cat test.py | highlight --syntax py

If there exist multiple suffixes (like C, cc, cpp, h for C++ - files),
they are mapped to a language definition in $CONF_DIR/filetypes.conf.

Highlight enters the batch processing mode if multiple input files are defined
or if --batch-recursive is set.
In batch mode, highlight will save the generated files using the original
filename, appending the extension of the chosen output type.
If files in the input directories happen to share the same name, the output
files will be prefixed with their source path name.
The --out-dir option is recommended in batch mode. Use --quiet to improve
performance (recommended for usage in shell scripts).

HTML, TeX, LaTeX and SVG output
-------------------------------

The HTML, TeX, LaTeX and SVG output formats allow to reference style definition
files which contain the formatting information (stylesheets).

In HTML and SVG output, this file contains CSS definitions and is saved as
'highlight.css'. In LaTeX and TeX, it contains macro definitions, and is saved
as 'highlight.sty'.

Name and path of the stylesheet may be modified with --style-outfile.
If the --outdir option is given, all generated output, including stylesheets,
are stored in this directory.

Use --include-style to embed the style information in the output documents
without referencing a stylesheet.

Referenced style definitions have the advantage to share all formatting
information in a single file, which affects all referencing documents.

With --style-infile you define a file to be included in the final formatting
information of the document. This way you enhance or redefine the default
highlight style definitions without editing generated code.
Note: Using a plug-in script is the preferred way to enhance styling.

Terminal output:
----------------

Since there are limited colours defined for ANSI terminal output, there exists
only one hard coded colour theme with --out-format=ansi. You should therefore
use --out-format=xterm256 to enable output in 256 colours. The 256 colour mode
is supported by recent releases of xterm, rxvt and Putty (among others).

highlight --out-format=ansi <inputfile> | less -R
highlight --out-format=xterm256 <inputfile> | less -R

Text processing:
----------------

If the language definition is specified as "txt", no highlighting takes place.

highlight -S txt --out-format=latex README > README.tex


Examples
--------

The following commands write the content of hello.c to hello.html:

highlight -o hello.html -i hello.c
highlight -o hello.html hello.c
highlight -o hello.html --syntax c < hello.c
highlight --syntax c < hello.c > hello.html

Apart from hello.html, a file highlight.css is generated in the current working
directory.

highlight --out-format=xhtml  --batch-recursive '*.cpp' --outdir ~/html_code/
This command converts all *.cpp files in the current directory and its sub-
directories to xhtml files, and stores the output in /home/you/html_code.

highlight -out-format=latex  * --outdir /home/you/latex_code/
This command onverts all files to LaTeX, stored in /home/you/latex_code/.

highlight -c stdout -s seashell --print-style
This command prints only the CSS information to stdout (theme: Seashell).


2.5 GNU SOURCE-HIGHLIGHT COMPATIBILITY
-------------------------------------------------------------------------------

The command line interface is extensively harmonised with source-highlight
(http://www.gnu.org/software/src-highlite/).

The following highlight options have the same meaning as in source-highlight:
 --input, --output, --help, --version, --out-format, --title, --data-dir,
 --verbose, --quiet

These options were added to enhance compatibility:
 --css, --doc, --failsafe, --line-number, --line-number-ref, --no-doc, --tab,
 --output-dir, --src-lang

These switches provide a common highlighter interface for scripts, plugins etc.


2.6 ADVANCED OPTIONS
-------------------------------------------------------------------------------

Prevent parsing of binary input files
-------------------------------------

If highlight could be invoked with all kinds of input, you can disable parsing
of binary files using --validate-input. This flag causes highlight to match the
input file header with a list of magic numbers. If a binary file type is
detected, highlight quits with an error message. This switch also removes an
UTF-8 BOM in the output.

Highlight nested code without starting delimiter
------------------------------------------------

If a file starts with an embedded code section which misses an appropriate opening
delimiter, the --start-nested option will switch to the nested language mode.
This can happen with LuaTeX files:
highlight luatex.tex --latex --start-nested=inc_luatex

inc_luatex is a Lua language definition with TeX line comments.
Note that the nested code section has to end with the ending delimiter defined
in the host language definition.

Test new configuration scripts
------------------------------

The option --config-file helps to test new config files before installing them.
The given file must be a lang or theme file.

highlight --config-file xxx.lang --config-file yyy.theme -I

Debug language definitions
--------------------------

Use --verbose to display the Lua and syntax data.

Remove an UTF8 BOM:
-------------------

Use --validate-input to get rid of UTF8 byte order marks.

Portable GUI (W32 build)
------------------------

Invoke highlight-gui.exe with the --portable switch to save its configuration
in text files instead of the registry.


3. CONFIGURATION
-------------------------------------------------------------------------------

3.1 FILE FORMAT
-------------------------------------------------------------------------------

Configuration files are Lua scripts. 
Please refer to http://www.lua.org/manual/5.1/manual.html for more details
about the Lua syntax.

These constructs are sufficient to edit the scripts:

Variable assigment:
name = value
(variables have no type, only values have)

Strings:
string1="string literal with escape: \n"
string2=[[raw string without escape sequence]]

If raw string content starts with "[" or ends with "]", pad the paranthesis
with space to avoid a syntax error. Highlight will strip the string.
If the string is a regular expression containing a set with a character class
like [[:space:]], use string delimiters with a "filler": [=[ regex string ]=]

Comments:
-- line comment
--[[ block comment ]]

Arrays:
array = { first=1, second="2", 3, { 4,5 } }
Arrays may contain variables and can be nested.


3.2 LANGUAGE DEFINITIONS
-------------------------------------------------------------------------------

A language definition describes all elements of a programming language which
will be highlighted by different colours and font types.
Save the new file in $HL_DIR/langDefs, using the following name convention:
<usual extension of sourcecode files>.lang

Examples: PHP -> php.lang, Java -> java.lang
If there exist multiple suffixes, list them in $HL_DIR/filetypes.conf.


Syntax elements:

Keywords = { Id, List|Regex, Group? }

  Id:    Integer, keyword group id (values 1-4, can be reused for several keyword
          groups)
  List:  List, list of keywords
  Regex: String, regular expression
  Group: Integer, capturing group id of regular expression, defines part of regex
         which should be returned as keyword (optional; if not set, the match
         with the highest group number is returned (counts from left to right))


Comments = { {Block, Nested?, Delimiter={Open, Close?} }

  Block:     Boolean, true if comment is a block comment
  Nested:    Boolean, true if block comments can be nested (optional)
  Delimiter: List, contains open delimiter regex (line comment) or open and close
             delimiter regexes (block comment)


Strings = { Delimiter|DelimiterPairs={Open, Close, Raw?}, Escape?, Interpolation?,
            RawPrefix?, AssertEqualLength? }

  Delimiter:         String, regular expression which describes string delimiters
  DelimiterPairs:    List, includes open and close delimiter expressions if not
                     equal, includes optional Raw flag as boolean which marks
                     delimiter pair to contain a raw string
  Escape:            String, regex of escape sequences (optional)
  Interpolation:     String, regex of interpolation sequences (optional)
  RawPrefix:         String, defines raw string indicator (optional)
  AssertEqualLength: Boolean, set true if delimiters must have the same length


PreProcessor = { Prefix, Continuation? }

  Prefix:        String, regular expression which describes open delimiter
  Continuation:  String, contains continuation character (optional)


NestedSections = {Lang, Delimiter= {} }

  Lang:      String, name of nested language
  Delimiter: List, contains open and close delimiters of the code section


Description:       String, Defines syntax description

Identifiers:       String, Regular expression which defines identifiers
                   (optional)

Operators:         String, Regular expression which defines operators

EnableIndentation: Boolean, set true if syntax may be reformatted and indented

IgnoreCase:        Boolean, set true if keyword case should be ignored


Global variables:

The following variables are available within a language definition:

hl_lang_dir: path of language definition directory (use with Lua dofile function)

Identifiers: Default regex for identifiers
Digits:      Default regex for numbers

The following integer variables represent the internal highlighting states:

  Attributes4,
}

AttributesN: Formatting of keyword group N. There should be at least four items
             to match the number of keyword groups defined in the language
             definitions

Example:

Default        = { Colour="#000000" }
Canvas         = { Colour="#ffffff" }
Number         = { Colour="#000000" }
Escape         = { Colour="#bd8d8b" }
String         = { Colour="#bd8d8b" }
StringPreProc  = { Colour="#bd8d8b" }
BlockComment   = { Colour="#ac2020", Italic=true }
PreProcessor   = { Colour="#000000" }
LineNum        = { Colour="#555555" }
Operator       = { Colour="#000000" }
LineComment = BlockComment

Keywords = {
  { Colour= "#9c20ee", Bold=true },
  { Colour= "#208920" },
  { Colour= "#0000ff" },
  { Colour= "#000000" },
}


3.5 KEYWORD GROUPS
-------------------------------------------------------------------------------

You may define custom keyword groups and corresponding highlighting styles.
This is useful if you want to highlight functions of a third party library,
macros, constants etc.

You define a new group in two steps:

 1. Define a new group in your language definition (lang file):

    Keywords = {
      -- add your keyword description:
      {Id=5, List = {"ERROR", "DEBUG", "WARN"} }
    }

 2. Add a corresponding highlighting style in your colour theme (theme file):

    Keywords= {
      --add your keyword style as 5th item in the list:
      { Colour= "#ff0000", Bold=true },
    }

It is recommended to define keyword groups in user-defined plugin scripts to
avoid editing of original highlight files.
See the cpp_qt.lua sample plug-in script and README_PLUGINS for details.


3.6 PLUG-INS
-------------------------------------------------------------------------------

The --plug-in option receives the path of a Lua script which overrides or
enhances the settings of theme and language definition files. Plug-ins make
it possible to apply costum settings without the need to edit installed
configuration files.
You can apply multiple plugins by using the --plug-in option more than once.

See README_PLUGINS for a detailed description and examples of packaged plugins.


3.7 FILE MAPPING
-------------------------------------------------------------------------------

The script filetypes.conf assigns file extensions and shebang descriptions to
language definitions.

Format:

FileMapping={
  {  Lang, Extensions|Shebang },
}

Lang:       String, name of language definition
Extensions: list of strings, contains file extensions referring to "Lang"
Shebang:    String, Regular expression which matches the first line of the input
            file

Edit the file gui_files/ext/fileopenfilter.conf to add new syntax types to
the GUI's file open filter.


3.8 CONFIG FILE SEARCH
-------------------------------------------------------------------------------

Since release 3.14 the configuration scripts are searched in the following
directories:

1. ~/.highlight/
2. user defined directory set with --data-dir (deprecated option)
3. /usr/share/highlight/
4. /etc/highlight/ (location of filetypes.conf)
5. current working directory (fallback)

These subdirectories are expected to contain the corresponding scripts:
-langDefs: *.lang
-themes: *.theme
-plugins: *.lua

A custom filetypes.conf may be placed directly in ~/.highlight/.
This search order enables you to enhance the installed scripts without the need
to copy all preinstalled files somewhere else.
As the --plug-in option of older releases accepted absolute paths only, the 
given plugin scripts will be searched in the directories above only if the
absolute file path access fails.


4. EMBEDDING HIGHLIGHT
-------------------------------------------------------------------------------

4.1 SAMPLE SCRIPTS
-------------------------------------------------------------------------------

See the examples subdirectory in the highlight package for some scripts in PHP,
Perl and Python  which invoke highlight and retrieve its output as string.
These scripts may be used as reference to develop plug-ins for other apps.

4.2 SWIG
-------------------------------------------------------------------------------

A SWIG interface file is located in /examples/swig.
See README_SWIG for installation instructions and the example scripts as
programming reference.

4.3 TCL
-------------------------------------------------------------------------------

A TCL extension is located in /examples/tcl.
See README_TCL for installation instructions.


4.4 THIRD PARTY SCRIPTS AND PLUG-INS
-------------------------------------------------------------------------------

See the /examples/web_plugins subdirectory in the highlight package for
some plugins which integrate highlight in Wiki and Blogging software:

-DokuWiki
-MovableType
-Wordpress
-Serendipity
