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

The HTML, TeX, LaTeX and SVG output formats allow to reference a stylesheet file which contains the formatting information.

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 stylesheets 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.

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). The latest terminal emulators also support 16m colors, this mode is enabled with --out-format=truecolor.

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

If highlight might process untrusted 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.

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 be useful with LuaTeX files:

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

The option --config-file helps to test new config files. The argument file must be a lang or theme.

Use --verbose to display Lua and syntax data.

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

Use --stdout to write output files in batch mode to stdout.

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

<usual extension of sourcecode files>.lang

The following variables are available within a language definition:

The following integer variables represent the internal highlighting states:

• HL_STANDARD

• HL_STRING

• HL_NUMBER

• HL_LINE_COMMENT

• HL_BLOCK_COMMENT

• HL_ESC_SEQ

• HL_PREPROC

• HL_PREPROC_STRING

• HL_OPERATOR

• HL_INTERPOLATION

• HL_LINENUMBER

• HL_KEYWORD

• HL_STRING_END

• HL_LINE_COMMENT_END

• HL_BLOCK_COMMENT_END

• HL_ESC_SEQ_END

• HL_PREPROC_END

• HL_OPERATOR_END

• HL_INTERPOLATION_END

• HL_KEYWORD_END

• HL_EMBEDDED_CODE_BEGIN

• HL_EMBEDDED_CODE_END

• HL_IDENTIFIER_BEGIN

• HL_IDENTIFIER_END

• HL_UNKNOWN

• HL_REJECT

This function is a hook which is called if an internal state changes (e.g. from HL_STANDARD to HL_KEYWORD if a keyword is found). It can be used to alter the new state or to manipulate syntax elements like keyword lists.

Return HL_REJECT if the recognized token and state should be discarded; the first character of token will be outputted and highlighted as oldState.

See README_PLUGINS for more available functions.
