## Name

mime.types - mime type description file for cups

## Description

The mime.types file defines the recognized file types.

Additional file types can be added to mime.types or (preferably) in additional files in the CUPS configuration directory with the extension ".types".

Each line in the mime.types file is a comment, blank, or rule line. Comment lines start with the # character. Rule lines start with the MIME type name and are optionally followed by a series of file recognition rules that are used to automatically identify print and web files:

        super/type rule [ ... ruleN]

The rules may be grouped using parenthesis, joined using "+" for a logical AND and "," or whitespace for a logical OR, and negated using "!".

## Rules

Rules take two forms - a filename extension by itself and functions with test values inside parenthesis. The following functions are available:

match("pattern")
  Pattern match on filename
ascii(offset,length)
  True if bytes are valid printable ASCII (CR, NL, TAB, BS, 32-126)
printable(offset,length)
  True if bytes are printable 8-bit chars (CR, NL, TAB, BS, 32-126, 128-254)
string(offset,"string")
  True if bytes are identical to string
istring(offset,"string")
  True if a case-insensitive comparison of the bytes is identical
char(offset,value)
  True if byte is identical
short(offset,value)
  True if 16-bit integer is identical
int(offset,value)
  True if 32-bit integer is identical
locale("string")
  True if current locale matches string
contains(offset,range,"string")
  True if the range contains the string

## String Constants

String constants can be specified inside quotes ("") for strings containing whitespace and angle brackets (<>) for hexadecimal strings.
