+2007-01-18 05:29 Anon Ymous <do@not.spam.me>
+	
+	* Move the "type" detection code from parse() into its own table
+	  driven routine.  This avoids maintaining multiple lists in
+	  file.h.
+
+	* Add an optional conditional field (ust before the type field).
+	  This code is wrapped in "#ifdef ENABLE_CONDITIONALS" as it is
+	  likely to go away.

+
+	* Fix an initialization bug in check_mem().
+
+2007-01-16 14:58 Anon Ymous <do@not.spam.me>
+
+	* Add a "default" type to print a message if nothing previously
+	  matched at that level or since the last default at that
+	  level.  This is useful for setting up switch-like statements.
+	  It can also be used to do if/else constructions without a
+	  redundant second test.
+
+	* Fix the "x" special case test so that one can test for that
+	  string with "=x".
+
+	* Allow "search" to search the entire buffer if the "/N"
+	  search count is missing.
+
+	* Make "regex" work!  It now starts its search at the
+	  specified offset and takes an (optional) "/N" line count to
+	  specify the search range; otherwise it searches to the end
+	  of the file.  The match is now grabbed correctly for format
+	  strings and the offset set to the end of the match.
+
+	* Add a "/s" flag to "regex" and "search" to set the offset to
+	  the start of the match.  By default the offset is set to the
+	  end of the match, as it is with other tests.  This is mostly
+	  useful for "regex".
+
+	* Make "search", "string" and "pstring" use the same
+	  file_strncmp() routine so that they support the same flags;
+	  "bestring16" and "lestring16" call the same routine, but
+	  with flags = 0.  Also add a "/C" flag (in analogy to "/c")
+	  to ignore the case on uppercase (lowercase) characters in
+	  the test string.
+
+	* Strict adherence to C style string escapes.  A warnings are
+	  printed when compiling.  Note: previously "\a" was
+	  incorrectly translated to 'a' instead of an <alert> (i.e.,
+	  BELL, typically 0x07).
+
+	* Make this compile with "-Wall -Wextra" and all the warning
+	  flags used with WARNS=4 in the NetBSD source.  Also make it
+	  pass lint.
+
+	* Many "cleanups" and hopefully not too many new bugs!

 Maintenance notes:
 
 I am continuing to maintain the file command. I welcome your help,
 but to make my life easier I'd like to request the following:
 
-- Don't change the version numbers!
-
-If your changes are extensive, I will have to work hard to 
-integrate them into my version.  If you check it into SCCS locally,
-the version numbers will likely be kept. IF you check it into RCS
-or CVS locally, please use -k to keep the version numbers, and
-please use branch deltas (1.21.1, 1.21.2, ...).  If you don't do
-this, I will likely be unable to use your changes; life's just too
-short.
-
 - Do not distribute changed versions.

 The language tests look for particular strings (cf

+.Nd file command's magic number file
+.Sh DESCRIPTION
 This manual page documents the format of the magic file as
 used by the
-.BR file (__CSECTION__)
+.Xr file __CSECTION__
 command, version __VERSION__.
 The
-.BR file
+.Xr file __CSECTION__
 command identifies the type of a file using,
 among other tests,
 a test for whether the file begins with a certain
-.IR "magic number" .
+.Dq "magic number" .
 The file
-.I __MAGIC__
+.Pa __MAGIC__
 specifies what magic numbers are to be tested for,
 what message to print if a particular magic number is found,
 and additional information to extract from the file.
-.PP
+.Pp
 Each line of the file specifies a test to be performed.
 A test compares the data starting at a particular offset
 in the file with a 1-byte, 2-byte, or 4-byte numeric value or
 a string.
 If the test succeeds, a message is printed.
 The line consists of the following fields:
-.IP offset \w'message'u+2n
+.Bl -tag -width ".Dv message"
+.It Dv offset
 A number specifying the offset, in bytes, into the file of the data
 which is to be tested.
-.IP type
+.It Dv type
 The type of the data to be tested.
 The possible values are:
-.RS
-.IP byte \w'message'u+2n
+.Bl -tag -width ".Dv lestring16"
+.It Dv byte
 A one-byte value.
-.IP short
+.It Dv short

-.IP regex
+.It Dv regex
 A regular expression match in extended POSIX regular expression syntax
 (much like egrep).
-The type specification can be optionally followed by
-.B /c
-for case-insensitive matches.
-The regular expression is always
-tested against the first
-.B N
+The type specification can be optionally followed by /[cse]*.
+The 
+.Dq c
+flag makes the match case insensitive, while the
+.Dq s
+or
+.Dq e
+flags update the offset to the starting or ending offsets of the
+match (only one should be used).
+By default, regex does not update the offset.
+The regular expression is always tested against the first
+.Dv N
 lines, where
-.B N
+.Dv N
 is the given offset, thus it
 is only useful for (single-byte encoded) text.
-.B ^
+.Dv ^
 and
-.B $
+.Dv $
 will match the beginning and end of individual lines, respectively,
 not beginning and end of file.
-.IP search
+.It Dv search
 A literal string search starting at the given offset. It must be followed by
-.B /<number>
+.Dv /<number>
 which specifies how many matches shall be attempted (the range).
 This is suitable for searching larger binary expressions with variable
 offsets, using
-.B \e
+.Dv \e
 escapes for special characters.
-.RE

+.It Dv default 
+This is intended to be used with the text
+.Dv x
+(which is always true) and a message that is to be used if there are
+no other matches.
+.El
+.El
+.Pp
 The numeric types may optionally be followed by
-.B &
+.Dv &
 and a numeric value,
 to specify that the value is to be AND'ed with the
 numeric value before any comparisons are done.
 Prepending a
-.B u
+.Dv u
 to the type indicates that ordered comparisons should be unsigned.
-.IP test
+.Bl -tag -width ".Dv message"
+.It Dv test
 The value to be compared with the value from the file.
 If the type is
 numeric, this value
 is specified in C form; if it is a string, it is specified as a C string
 with the usual escapes permitted (e.g. \en for new-line).
-.IP
+.Pp
 Numeric values
 may be preceded by a character indicating the operation to be performed.
 It may be
-.BR = ,
+.Dv = ,
 to specify that the value from the file must equal the specified value,
-.BR < ,
+.Dv < ,
 to specify that the value from the file must be less than the specified
 value,
-.BR > ,
+.Dv > ,
 to specify that the value from the file must be greater than the specified
 value,
-.BR & ,
+.Dv & ,
 to specify that the value from the file must have set all of the bits
 that are set in the specified value,
-.BR ^ ,
+.Dv ^ ,
 to specify that the value from the file must have clear any of the bits
 that are set in the specified value, or
-.BR ~ ,
+.Dv ~ ,
 the value specified after is negated before tested.
-.BR x ,
+.Dv x ,
 to specify that any value will match.
 If the character is omitted, it is assumed to be
-.BR = .
+.Dv = .
 For all tests except
-.B string
+.Em string
 and
-.B regex,
+.Em regex,
 operation
-.BR !
+.Dv !
 specifies that the line matches if the test does
-.B not
+.Em not
 succeed.
-.IP
+.Pp
 Numeric values are specified in C form; e.g.
-.B 13
+.Dv 13
 is decimal,
-.B 013
+.Dv 013
 is octal, and
-.B 0x13
+.Dv 0x13
 is hexadecimal.
-.IP
+.Pp
 For string values, the byte string from the
 file must match the specified byte string.
 The operators
-.BR = ,
-.B <
+.Dv = ,
+.Dv <
 and
-.B >
+.Dv >
 (but not
-.BR & )
+.Dv & )
 can be applied to strings.
 The length used for matching is that of the string argument
 in the magic file.
 This means that a line can match any string, and
 then presumably print that string, by doing
-.B >\e0
+.Em >\e0
 (because all strings are greater than the null string).
-.IP message
+.Pp
+The special test
+.Em x
+always evaluates to true.
+.Dv message
 The message to be printed if the comparison succeeds.  If the string
 contains a
-.BR printf (3)
+.Xr printf 3
 format specification, the value from the file (with any specified masking
 performed) is printed using the message as the format string.
-.PP
+If the string begins with ``\\b'', the message printed is the
+remainder of the string with no whitespace added before it: multiple
+matches are normally separated by a single space.
+.El
+.Pp
 Some file formats contain additional information which is to be printed
 along with the file type or need additional tests to determine the true
 file type.
 These additional tests are introduced by one or more
-.B >
+.Em >
 characters preceding the offset.
 The number of
-.B >
+.Em >
 on the line indicates the level of the test; a line with no
-.B >
+.Em >
 at the beginning is considered to be at level 0.
 Tests are arranged in a tree-like hierarchy:
 If a the test on a line at level
-.IB n
+.Em n
 succeeds, all following tests at level
-.IB n+1
+.Em n+1
 are performed, and the messages printed if the tests succeed, untile a line
 with level
-.IB n
+.Em n
 (or less) appears.
 For more complex files, one can use empty messages to get just the
 "if/then" effect, in the following way:
-.sp
-.nf
-    0      string   MZ
-    >0x18  leshort  <0x40   MS-DOS executable
-    >0x18  leshort  >0x3f   extended PC executable (e.g., MS Windows)
-.fi
-.PP
+.Bd -literal -offset indent 
+0      string   MZ
+>0x18  leshort  <0x40   MS-DOS executable
+>0x18  leshort  >0x3f   extended PC executable (e.g., MS Windows)
+.Ed
+.Pp
 Offsets do not need to be constant, but can also be read from the file
 being examined.
 If the first character following the last
-.B >
+.Em >
 is a
-.B (
+.Em (
 then the string after the parenthesis is interpreted as an indirect offset.
 That means that the number after the parenthesis is used as an offset in
 the file.
 The value at that offset is read, and is used again as an offset
 in the file.
 Indirect offsets are of the form:
-.BI (( x [.[bslBSL]][+\-][ y ]).
+.Em (( x [.[bslBSL]][+\-][ y ]).
 The value of
-.I x
+.Em x
 is used as an offset in the file. A byte, short or long is read at that offset
 depending on the
-.B [bslBSLm]
+.Em [bslBSLm]
 type specifier.
 The capitalized types interpret the number as a big endian
 value, whereas the small letter versions interpret the number as a little
 endian value;
 the
-.B m
+.Em m
 type interprets the number as a middle endian (PDP-11) value.
 To that number the value of
-.I y
+.Em y
 is added and the result is used as an offset in the file.
 The default type if one is not specified is long.
-.PP
+.Pp
 That way variable length structures can be examined:
-.sp
-.nf
-    # MS Windows executables are also valid MS-DOS executables
-    0           string  MZ
-    >0x18       leshort <0x40   MZ executable (MS-DOS)

+>>(0x3c.l)  string  LX\e0\e0  LX executable (OS/2)
+.Ed
+.Pp
 This strategy of examining has one drawback: You must make sure that
 you eventually print something, or users may get empty output (like, when
 there is neither PE\e0\e0 nor LE\e0\e0 in the above example)
-.PP
+.Pp
 If this indirect offset cannot be used as-is, there are simple calculations
 possible: appending
-.BI [+-*/%&|^]<number>
+.Em [+-*/%&|^]<number>
 inside parentheses allows one to modify
 the value read from the file before it is used as an offset:
-.sp
-.nf
-    # MS Windows executables are also valid MS-DOS executables
-    0           string  MZ
-    # sometimes, the value at 0x18 is less that 0x40 but there's still an

-    >>(4.s*512) leshort 0x014c  COFF executable (MS-DOS, DJGPP)

+.Pp
 Sometimes you do not know the exact offset as this depends on the length or
 position (when indirection was used before) of preceding fields. You can
 specify an offset relative to the end of the last up-level field using
-.BI &
+.Sq &
 as a prefix to the offset:
-.sp
-.nf
-    0           string  MZ

 Finally, if you have to deal with offset/length pairs in your file, even the
 second value in a parenthesized expression can be taken from the file itself,
 using another set of parentheses. Note that this additional indirect offset
 is always relative to the start of the main indirect offset.
