Gets the shortcut name from the file name. This essentially |
103
|
|
|
|
|
|
|
gets the base name of the file name. This is the same name |
104
|
|
|
|
|
|
|
that the shortcut readers will return. |

132
|
|
|
|
|
|
|
|
133
|
|
|
|
|
|
|
Reads the specified file and extracts the contents. The type of |
134
|
|
|
|
|
|
|
shortcut file is determined by the file extension. A hash will be returned |
135
|
|
|
|
|
|
|
containing two keys: "name" and "url". The name is the name/title of |
136
|
|
|
|
|
|
|
the shortcut. A hash will always be returned - if there is an error |
137
|
|
|
|
|
|
|
reading the file, the routine will die with an appropriate error message. |
138
|
|
|
|
|
|
|
|
139
|
|
|
|
|
|
|
For ".desktop" and ".url" files, the reader can handle unicode characters |
140
|
|
|
|
|
|
|
in the name and URL. ".webloc" files may contain unicode characters as well, |
141
|
|
|
|
|
|
|
although this functionality still requires more testing. |
142
|
|
|
|
|
|
|
|
143
|
|
|
|
|
|
|
The name returned by the readers is a guess. Many shortcut files |
144
|
|
|
|
|
|
|
do not contain a name/title embedded in the file. ".desktop" shortcuts |
145
|
|
|
|
|
|
|
may contain several embedded names with different encodings. Unfortunately, |
146
|
|
|
|
|
|
|
these names are not necessarily updated when the shortcut is renamed. |
147
|
|
|
|
|
|
|
It is difficult, if not impossible, to determine which is the correct name. |
148
|
|
|
|
|
|
|
As of right now, the reader will always return the name of the file as the |
149
|
|
|
|
|
|
|
name of the shortcut, although this may change in the future. |

Note: The Mac::PropertyList module (http://search.cpan.org/~bdfoy/Mac-PropertyList/) |
152
|
|
|
|
|
|
|
must be installed in order to read ".webloc" files. |

These routines operate essentially the same way as read_shortcut_file. |
241
|
|
|
|
|
|
|
However, they force the file to be parsed as a particular type, |
242
|
|
|
|
|
|
|
regardless of the file extension. These should be used sparingly. |
243
|
|
|
|
|
|
|
You should use read_shortcut_file unless you have a good |
244
|
|
|
|
|
|
|
reason not to. |
