[bug-mailutils] Mimeview is unable to parse mime.types file

[Pierre-Jean]

Hello alls,

Mimeview is unable to parse my current mime.types file:
  mimeview -t /usr/share/cups/mime/mime.types file
  Invalid character '^', state 1
  Aborted (core dump)

Mimeview seems to be unable to parse the regex rule of the
file mime.types. Apparently, that regex rule was introduced
for the sole pdf detection, and is not documented in man 5
mime.types. I found the commit which adds that rule on the
cups repository:
https://github.com/apple/cups/commit/6ee54c072996fd4cde3d5a53e80918e90f8e29c5

But, even with that rule commented, mimeview is still unable
to parse the file:
  mimeview -t /usr/share/cups/mime/mime.types file
  mimeview: /usr/share/cups/mime/mime.types:86: syntax error
  mimeview: /usr/share/cups/mime/mime.types:94: syntax error
  mimeview: /usr/share/cups/mime/mime.types:125: syntax error
  mimeview: /usr/share/cups/mime/mime.types:148: syntax error
  mimeview: /usr/share/cups/mime/mime.types:156: syntax error
  mimeview: /usr/share/cups/mime/mime.types:177: syntax error


Cups 2.2.3
mailutils (GNU Mailutils) 3.2.91-15 [release-3.2-40-gd2952d1c8-dirty]
my /usr/share/cups/mime/mime.types is joined.

Kind regards,
Pierre-Jean.

#   extension                           Pattern match on "*.extension"
#   ascii(offset,length)                True if bytes are valid printable ASCII
#                                       (CR, NL, TAB, BS, 32-126)
#   priority(number)                    Sets priority of type (0=lowest,
#                                       100=default, 200=highest)
#   printable(offset,length)            True if bytes are printable 8-bit chars
#                                       (CR, NL, TAB, BS, 32-126, 128-254)
#   regex(offset,"regex")               True if bytes match regular expression
#   string(offset,"string")             True if bytes are identical to string
#   istring(offset,"string")            True if bytes are identical to
#                                       case-insensitive string
#   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
#
# General Notes:
#
#   MIME type names are case-insensitive.  Internally they are converted
#   to lowercase.  Multiple occurrences of a type will cause the provided
#   rules to be appended to the existing definition.  If two types use the same
#   rules to resolve a type and have the same priority, e.g. "doc" extension for
#   "text/bar" and "text/foo", the returned type will be the first type as
#   sorted in alphanumerically ascending order without regard to case.  Thus,
#   the "text/bar" type will match the "doc" extension first unless the
#   "text/foo" type has specified a higher priority.
#
#   The "printable" rule differs from the "ascii" rule in that it also
#   accepts 8-bit characters in the range 128-255.
#
#   String constants must be surrounded by "" if they contain whitespace.
#   To insert binary data into a string, use the <hex> notation.
