Mac OS (Classic) users should note a few differences. Since
Mac OS is not Unix, when the glob code encounters a tilde glob (e.g.
-~user/foo) and the C<GLOB_TILDE> flag is used, it simply returns that
+~user) and the C<GLOB_TILDE> flag is used, it simply returns that
pattern without doing any expansion.
Glob on Mac OS is case-insensitive by default (if you don't use any
begin with a ':'. If specifying a volume name only, a trailing ':' is
required.
+The specification of pathnames in glob patterns adheres to the usual Mac
+OS conventions: The path separator is a colon ':', not a slash '/'. A
+full path always begins with a volume name. A relative pathname on Mac
+OS must always begin with a ':', except when specifying a file or
+directory name in the current working directory, where the leading colon
+is optional. If specifying a volume name only, a trailing ':' is
+required. Due to these rules, a glob like E<lt>*:E<gt> will find all
+mounted volumes, while a glob like E<lt>*E<gt> or E<lt>:*E<gt> will find
+all files and directories in the current directory.
+
+Note that updirs in the glob pattern are resolved before the matching begins,
+i.e. a pattern like "*HD:t?p::a*" will be matched as "*HD:a*". Note also,
+that a single trailing ':' in the pattern is ignored (unless it's a volume
+name pattern like "*HD:"), i.e. a glob like E<lt>:*:E<gt> will find both
+directories I<and> files (and not, as one might expect, only directories).
+You can, however, use the C<GLOB_MARK> flag to distinguish (without a file
+test) directory names from file names.
+
+If the C<GLOB_MARK> flag is set, all directory paths will have a ':' appended.
+Since a directory like 'lib:' is I<not> a valid I<relative> path on Mac OS,
+both a leading and a trailing colon will be added, when the directory name in
+question doesn't contain any colons (e.g. 'lib' becomes ':lib:').

+full path always begins with a volume name. A relative pathname on Mac
+OS must always begin with a ':', except when specifying a file or
+directory name in the current working directory, where the leading colon
+is optional. If specifying a volume name only, a trailing ':' is
+required. Due to these rules, a glob like E<lt>*:E<gt> will find all
+mounted volumes, while a glob like E<lt>*E<gt> or E<lt>:*E<gt> will find
+all files and directories in the current directory.
+
+Note that updirs in the glob pattern are resolved before the matching begins,
+i.e. a pattern like "*HD:t?p::a*" will be matched as "*HD:a*". Note also,
+that a single trailing ':' in the pattern is ignored (unless it's a volume
+name pattern like "*HD:"), i.e. a glob like <:*:> will find both directories
+I<and> files (and not, as one might expect, only directories).
+
+The metachars '*', '?' and the escape char '\' are valid characters in
+volume, directory and file names on Mac OS. Hence, if you want to match
+a '*', '?' or '\' literally, you have to escape these characters. Due to
+perl's quoting rules, things may get a bit complicated, when you want to
+match a string like '\*' literally, or when you want to match '\' literally,
+but treat the immediately following character '*' as metachar. So, here's a
+rule of thumb (applies to both single- and double-quoted strings): escape
+each '*' or '?' or '\' with a backslash, if you want to treat them literally,
+and then double each backslash and your are done. E.g.
+
+- Match '\*' literally
+
+ escape both '\' and '*' : '\\\*'
+ double the backslashes : '\\\\\\*'
+
+(Internally, the glob routine sees a '\\\*', which means that both '\' and
+'*' are escaped.)
+
+
+- Match '\' literally, treat '*' as metachar
+
+ escape '\' but not '*' : '\\*'
+ double the backslashes : '\\\\*'
+
+(Internally, the glob routine sees a '\\*', which means that '\' is escaped and
+'*' is not.)
+
+Note that you also have to quote literal spaces in the glob pattern, as described
+above.

File::Spec::Mac - File::Spec for MacOS
=item catdir
-Concatenate two or more directory names to form a complete path ending with
-a directory. Put a trailing : on the end of the complete path if there
-isn't one, because that's what's done in MacPerl's environment.
+Concatenate two or more directory names to form a path separated by colons
+(":") ending with a directory. Automatically puts a trailing ":" on the
+end of the complete path, because that's what's done in MacPerl's
+environment and helps to distinguish a file path from a directory path.
+
+The intended purpose of this routine is to concatenate I<directory names>.
+But because of the nature of Macintosh paths, some additional possibilities
+are allowed to make using this routine give reasonable results for some
+common situations. In other words, you are also allowed to concatenate
+I<paths> instead of directory names (strictly speaking, a string like ":a"
+is a path, but not a name, since it contains a punctuation character ":").
+
+Here are the rules that are used: Each argument has its trailing ":" removed.
+Each argument, except the first, has its leading ":" removed. They are then
+joined together by a ":" and a trailing ":" is added to the path.
+
+So, beside calls like
+
+ File::Spec->catdir("a") = "a:"
+ File::Spec->catdir("a","b") = "a:b:"
+ File::Spec->catdir("","a","b") = ":a:b:"
+ File::Spec->catdir("a","","b") = "a::b:"
+ File::Spec->catdir("") = ":"
+ File::Spec->catdir("a","b","") = "a:b::" (!)
+ File::Spec->catdir() = "" (special case)
+
+calls like the following
-The fundamental requirement of this routine is that
+ File::Spec->catdir("a:",":b") = "a:b:"
+ File::Spec->catdir("a:b:",":c") = "a:b:c:"
+ File::Spec->catdir("a:","b") = "a:b:"
+ File::Spec->catdir("a",":b") = "a:b:"
+ File::Spec->catdir(":a","b") = ":a:b:"
+ File::Spec->catdir("","",":a",":b") = "::a:b:"
+ File::Spec->catdir("",":a",":b") = ":a:b:" (!)
+ File::Spec->catdir(":") = ":"
- File::Spec->catdir(split(":",$path)) eq $path
+are allowed.
-But because of the nature of Macintosh paths, some additional
-possibilities are allowed to make using this routine give reasonable results
-for some common situations. Here are the rules that are used. Each
-argument has its trailing ":" removed. Each argument, except the first,
-has its leading ":" removed. They are then joined together by a ":".
+To get a path beginning with a ":" (a relative path), put a "" as the first
+argument. Beginning the first argument with a ":" (e.g. ":a") will also work
+(see the examples).
-So
+Since Mac OS (Classic) uses the concept of volumes, there is an ambiguity:
+Does the first argument in
- File::Spec->catdir("a","b") = "a:b:"
- File::Spec->catdir("a:",":b") = "a:b:"
- File::Spec->catdir("a:","b") = "a:b:"
- File::Spec->catdir("a",":b") = "a:b"
- File::Spec->catdir("a","","b") = "a::b"
+ File::Spec->catdir("LWP","Protocol");
-etc.
+denote a volume or a directory, i.e. should the path be relative or absolute?
+There is no way of telling except by checking for the existence of "LWP:" (a
+volume) or ":LWP" (a directory), but those checks aren't made here. Thus, according
+to the above rules, the path "LWP:Protocol:" will be returned, which, considered
+alone, is an absolute path, although the volume "LWP:" may not exist. Hence, don't
+forget to put a ":" in the appropriate place in the path if you want to
+distinguish unambiguously. (Remember that a valid relative path should always begin
+with a ":", unless you are specifying a file or a directory that resides in the
+I<current> directory. In that case, the leading ":" is not mandatory.)
-To get a relative path (one beginning with :), begin the first argument with :
-or put a "" as the first argument.
+With version 1.2 of File::Spec, there's a new method called C<catpath>, that
+takes volume, directory and file portions and returns an entire path (see below).
+While C<catdir> is still suitable for the concatenation of I<directory names>,
+you should consider using C<catpath> to concatenate I<volume names> and
+I<directory paths>, because it avoids any ambiguities. E.g.
-If you don't want to worry about these rules, never allow a ":" on the ends
-of any of the arguments except at the beginning of the first.
+ $dir = File::Spec->catdir("LWP","Protocol");
+ $abs_path = File::Spec->catpath("MacintoshHD:", $dir, "");
-Under MacPerl, there is an additional ambiguity. Does the user intend that
+yields
- File::Spec->catfile("LWP","Protocol","http.pm")
+ "MacintoshHD:LWP:Protocol:" .
-be relative or absolute? There's no way of telling except by checking for the
-existence of LWP: or :LWP, and even there he may mean a dismounted volume or
-a relative path in a different directory (like in @INC). So those checks
-aren't done here. This routine will treat this as absolute.

Concatenate one or more directory names and a filename to form a
complete path ending with a filename. Since this uses catdir, the
