31 | On MacOS, there's nothing to be done. Returns what it's given. |

40 | =item catdir |
41 | |
be708cc0 |
42 | Concatenate two or more directory names to form a path separated by colons |
43 | (":") ending with a directory. Automatically puts a trailing ":" on the |
44 | end of the complete path, because that's what's done in MacPerl's |
45 | environment and helps to distinguish a file path from a directory path. |
46 | |
47 | The intended purpose of this routine is to concatenate I<directory names>. |
48 | But because of the nature of Macintosh paths, some additional possibilities |
49 | are allowed to make using this routine give reasonable results for some |
50 | common situations. In other words, you are also allowed to concatenate |
51 | I<paths> instead of directory names (strictly speaking, a string like ":a" |
52 | is a path, but not a name, since it contains a punctuation character ":"). |
53 | |
54 | Here are the rules that are used: Each argument has its trailing ":" removed. |
55 | Each argument, except the first, has its leading ":" removed. They are then |
56 | joined together by a ":" and a trailing ":" is added to the path. |
57 | |
58 | So, beside calls like |
59 | |
60 | File::Spec->catdir("a") = "a:" |
61 | File::Spec->catdir("a","b") = "a:b:" |
62 | File::Spec->catdir("","a","b") = ":a:b:" |
63 | File::Spec->catdir("a","","b") = "a::b:" |
64 | File::Spec->catdir("") = ":" |
65 | File::Spec->catdir("a","b","") = "a:b::" (!) |
66 | File::Spec->catdir() = "" (special case) |
67 | |
68 | calls like the following |
270d1e39 |
69 | |
be708cc0 |
70 | File::Spec->catdir("a:",":b") = "a:b:" |
71 | File::Spec->catdir("a:b:",":c") = "a:b:c:" |
72 | File::Spec->catdir("a:","b") = "a:b:" |
73 | File::Spec->catdir("a",":b") = "a:b:" |
74 | File::Spec->catdir(":a","b") = ":a:b:" |
75 | File::Spec->catdir("","",":a",":b") = "::a:b:" |
76 | File::Spec->catdir("",":a",":b") = ":a:b:" (!) |
77 | File::Spec->catdir(":") = ":" |
270d1e39 |
78 | |
be708cc0 |
79 | are allowed. |
270d1e39 |
80 | |
be708cc0 |
81 | To get a path beginning with a ":" (a relative path), put a "" as the first |
82 | argument. Beginning the first argument with a ":" (e.g. ":a") will also work |
83 | (see the examples). |
270d1e39 |
84 | |
be708cc0 |
85 | Since Mac OS (Classic) uses the concept of volumes, there is an ambiguity: |
86 | Does the first argument in |
270d1e39 |
87 | |
be708cc0 |
88 | File::Spec->catdir("LWP","Protocol"); |
270d1e39 |
89 | |
be708cc0 |
90 | denote a volume or a directory, i.e. should the path be relative or absolute? |
91 | There is no way of telling except by checking for the existence of "LWP:" (a |
92 | volume) or ":LWP" (a directory), but those checks aren't made here. Thus, according |
93 | to the above rules, the path "LWP:Protocol:" will be returned, which, considered |
94 | alone, is an absolute path, although the volume "LWP:" may not exist. Hence, don't |
95 | forget to put a ":" in the appropriate place in the path if you want to |
96 | distinguish unambiguously. (Remember that a valid relative path should always begin |
97 | with a ":", unless you are specifying a file or a directory that resides in the |
98 | I<current> directory. In that case, the leading ":" is not mandatory.) |
270d1e39 |
99 | |
be708cc0 |
100 | With version 1.2 of File::Spec, there's a new method called C<catpath>, that |
101 | takes volume, directory and file portions and returns an entire path (see below). |
102 | While C<catdir> is still suitable for the concatenation of I<directory names>, |
103 | you should consider using C<catpath> to concatenate I<volume names> and |
104 | I<directory paths>, because it avoids any ambiguities. E.g. |
270d1e39 |
105 | |
be708cc0 |
106 | $dir = File::Spec->catdir("LWP","Protocol"); |
107 | $abs_path = File::Spec->catpath("MacintoshHD:", $dir, ""); |
270d1e39 |
108 | |
be708cc0 |
109 | yields |
270d1e39 |
110 | |
be708cc0 |
111 | "MacintoshHD:LWP:Protocol:" . |

132 | =item catfile |
133 | |
134 | Concatenate one or more directory names and a filename to form a |
135 | complete path ending with a filename. Since this uses catdir, the |
be708cc0 |
136 | same caveats apply. Note that the leading ":" is removed from the |
137 | filename, so that |
270d1e39 |
138 | |
be708cc0 |
139 | File::Spec->catfile("a", "b", "file"); # = "a:b:file" |

182 | |
183 | Returns a string representing the root directory. Under MacPerl, |
184 | returns the name of the startup volume, since that's the closest in |
be708cc0 |
185 | concept, although other volumes aren't rooted there. The name has a |
186 | trailing ":", because that's the correct specification for a volume |
187 | name on Mac OS. |

204 | |
be708cc0 |
205 | Returns the contents of $ENV{TMPDIR}, if that directory exits or the current working |
206 | directory otherwise. Under MacPerl, $ENV{TMPDIR} will contain a path like |
207 | "MacintoshHD:Temporary Items:", which is a hidden directory on your startup volume. |

231 | =item file_name_is_absolute |
232 | |
be708cc0 |
233 | Takes as argument a path and returns true, if it is an absolute path. |
234 | This does not consult the local filesystem. If |
235 | the path has a leading ":", it's a relative path. Otherwise, it's an |
236 | absolute path, unless the path doesn't contain any colons, i.e. it's a name |
237 | like "a". In this particular case, the path is considered to be relative |
238 | (i.e. it is considered to be a filename). Use ":" in the appropriate place |
239 | in the path if you want to distinguish unambiguously. As a special case, |
240 | the filename '' is always considered to be absolute. |
241 | |
242 | E.g. |
243 | |
244 | File::Spec->file_name_is_absolute("a"); # false (relative) |
245 | File::Spec->file_name_is_absolute(":a:b:"); # false (relative) |
246 | File::Spec->file_name_is_absolute("MacintoshHD:"); # true (absolute) |
247 | File::Spec->file_name_is_absolute(""); # true (absolute) |

263 | =item path |
264 | |
be708cc0 |
265 | Returns the null list for the MacPerl application, since the concept is |
266 | usually meaningless under MacOS. But if you're using the MacPerl tool under |
267 | MPW, it gives back $ENV{Commands} suitably split, as is done in |
270d1e39 |
268 | :lib:ExtUtils:MM_Mac.pm. |

284 | ($volume,$directories,$file) = File::Spec->splitpath( $path, $no_file ); |
285 | |
286 | Splits a path in to volume, directory, and filename portions. |
287 | |
288 | On Mac OS, assumes that the last part of the path is a filename unless |
289 | $no_file is true or a trailing separator ":" is present. |
290 | |
291 | The volume portion is always returned with a trailing ":". The directory portion |
292 | is always returned with a leading (to denote a relative path) and a trailing ":" |
293 | (to denote a directory). The file portion is always returned I<without> a leading ":". |
294 | Empty portions are returned as "". |
295 | |
296 | The results can be passed to L</catpath()> to get back a path equivalent to |
297 | (usually identical to) the original path. |

338 | |
339 | @dirs = File::Spec->splitdir( $directories ); |
340 | |
341 | $directories must be only the directory portion of the path on systems |
342 | that have the concept of a volume or that have path syntax that differentiates |
343 | files from directories. |
344 | |
345 | Unlike just splitting the directories on the separator, empty directory names |
346 | (C<"">) can be returned. Since C<catdir()> on Mac OS always appends a trailing |
347 | colon to distinguish a directory path from a file path, a single trailing colon |
348 | will be ignored, i.e. there's no empty directory name after it. |

455 | If $base is not present or '', then the current working directory is used. |
456 | If $base is relative, then it is converted to absolute form using C<rel2abs()>. |
457 | This means that it is taken to be relative to the current working directory. |
458 | |
459 | Since Mac OS has the concept of volumes, this assumes that both paths |
460 | are on the $destination volume, and ignores the $base volume (!). |
461 | |
462 | If $base doesn't have a trailing colon, the last element of $base is |
463 | assumed to be a filename. This filename is ignored (!). Otherwise all path |
464 | components are assumed to be directories. |
465 | |
466 | If $path is relative, it is converted to absolute form using C<rel2abs()>. |
467 | This means that it is taken to be relative to the current working directory. |
