NAME
Highlight - a universal sourcecode to formatted text converter
SYNOPSIS
highlight [OPTIONS]... [FILES]...
DESCRIPTION
Highlight converts sourcecode to HTML, XHTML, RTF, ODT, LaTeX, TeX, BB-
Code, Pango markup, SVG, XTERM or ANSI escape sequences. There are
several colour themes available. Highlight recognizes keywords, num-
bers, strings, comments, symbols and preprocessor directives. It sup-
ports about 180 programming languages, which are defined in Lua
scripts.
It's easily possible to enhance highlight's database of programming
languages and colour themes. See the README file for details.

p + the line number (default='line')
--output-dir=path
output directory
--failsafe

copied to the output
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. HTML will be generated unless an other output for-
mat is given. Style definitions are stored in highlight.css (HTML,
XHTML, SVG) or highlight.sty (LaTeX, TeX) if neither -c nor -I is
given. Reformatting code (-F) will only work with C, C++, C# and Java
input files.
BUGS
The wrapping options might cause faulty highlighting of long single
line comments.
FILES
The configuration files are stored in /usr/share/highlight/. Language
definitions, themes and plugins are located in subdirectories.
Documentation files are stored in /usr/share/doc/highlight/ , configu-
ration 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 subdirecto-
ries 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 (recom-
mended 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.
