NAME
     Highlight - a universal sourcecode to formatted text converter

SYNOPSIS
     highlight [OPTIONS]... [FILES]...

DESCRIPTION
     Highlight converts sourcecode to HTML, XHTML, RTF, ODT, LaTeX, TeX, BBCode,
     Pango  markup,  SVG,  XTERM  or  ANSI  escape sequences.  There are several
     colour themes available.  Highlight recognizes keywords, numbers,	strings,
     comments,	symbols and preprocessor directives.  It supports about 180 pro-
     gramming languages, which are defined in Lua scripts.

     It's easily possible to enhance highlight's database  of  programming  lan-
     guages and colour themes.	See the README file for details.

     --syntax-by-name=<name>
	    specify  type of source code by given name.  Will not read a file of
	    this name, useful for stdin and to determine the syntax of the  file

ENV VARIABLES
     Highlight recognizes these variables:

     HIGHLIGHT_DATADIR
	    sets the path to highlight's configuration scripts

     HIGHLIGHT_OPTIONS
	    may contain command line options, but no input file paths.

HINTS
     If no in- or output files are specified, stdin and stdout will be used  for
     in- or output.  Reading from stdin can also be triggered by the '-' option.

     Default  output  format:  xterm256 or truecolor if appropriate, HTML other-
     wise.

     Style definitions are stored in highlight.css (HTML, XHTML, SVG)  or  high-
     light.sty	(LaTeX, TeX) if neither -c nor -I is given. For CSS, definitions
     are stored in the output document header with -I, if -f is also given there
     will be no style definitions.

     Reformatting code (-F) will only work with C, C++, C# and Java input files.

     LSP features require absolute input paths and disable reformatting (-F).

BUGS
     Wrapping lines with -V or -W will cause faulty highlighting of long  single
     line  comments and directives.  Using line-range might interfere with multi
     line syntax elements. Use with caution.

FILES
     The configuration files are stored in /usr/share/highlight/.  Language def-
     initions, themes and plugins are located in subdirectories.

     Documentation files are stored in /usr/share/doc/highlight/,  configuration
     files in /etc/highlight/.

     See README how to install own scripts in the home directory.

EXAMPLES
     Single file conversion:

     highlight -o hello.html -i hello.c

     highlight -o hello.html hello.c

     highlight -o hello.html -S c < hello.c

     highlight -S c < hello.c > hello.html

     Note that a file highlight.css is created in the current directory.

     Batch file processing:

     highlight --out-format=xhtml  -B '*.cpp' -d /home/you/html_code/

     converts all *.cpp files in the current directory and its subdirectories to
     xhtml files, and stores the output in /home/you/html_code.

     highlight --out-format=latex  * -d /home/you/latex_code/

     converts all files to LaTeX, stored in /home/you/latex_code/.

     Use  --quiet  to  improve performance of batch file processing (recommended
     for usage in shell scripts).

     Use highlight --out-format=xterm256 <yourfile>  |	less  -R  to  display  a
     source file in a terminal.

     Run highlight --list-scripts=langs to see all supported syntax types.
