make-zsh-urls -- create F<~/.zsh/urls> hierarchy
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
% make-zsh-urls [B<OPTION>] ...
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
make-zsh-urls creates a hierarchy of files and directories under
|
|
F<~/.zsh/urls> for use by the _urls completion function in the new
|
|
completion system of zsh 3.1.6 and higher.
|
|
|
|
It needs the B<URI::Bookmarks> suite of modules to run, which are
|
|
available from CPAN, the Comprehensive Perl Archive Network.
|
|
See B<http://www.perl.com/cpan> or L<CPAN> for more information.
|
|
|
|
The following options are available:
|
|
|
|
B<--output-dir>, B<-o> Specify the output directory for the
|
|
hierarchy. Defaults to F<~/.zsh/urls>.
|
|
|
|
B<--input-file>, B<-i> Specify the input bookmarks file.
|
|
Defaults to F<~/.netscape/bookmarks.html>.
|
|
|
|
B<--root-node>, B<-r> Specify which folder contains the
|
|
bookmarks which the hierarchy will be
|
|
created from. Defaults to the root
|
|
of the bookmark collection tree.
