Highlight - a universal sourcecode to formatted text converter
highlight [OPTIONS]... [FILES]...
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 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.

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.
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 format
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.
The wrapping options might cause faulty highlighting of long
single line comments.
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/
, configuration files in /etc/highlight/.
See README how to install own scripts in the home directory.
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.
