# chilight(1)

highlight a C source file

## NAME

**chilight** – highlight a C source file

## SYNOPSIS

**chilight** \[**-V**\] \[**-f** *format*\] \[**-o** *file*\] \[**-t** *title*\] \[**-w** *width*\] \[*file ...*\]

## DESCRIPTION

The **chilight** utility colorizes the input file, expected to be written in the C language, with text attributes or markups.

The options are as follows:

- **-f** *format*

  Set the output format to *format*.\
   The format can be one of: *ansi\_color*, *ansi\_bold*, *html\_color*, *html\_font*, *roff* or *tty* (the default).

- **-o** *file*

  Set the output destination to *file*.

- **-t** *title*

  Specify the page title for the generated HTML page.

- **-V**

  Print version information on standard output then exit.

- **-w** *width*

  Set the tab width for the roff style.\
   Tabulator characters are converted to suitable amounts of space characters to gain better typographic quality on roff output. Acceptable values are in the range 1..16 which should be ample for most situations.
