Mozilla/Firefox bookmarks as fvwm menu

I’m neither sure if the place is right nor if this is of any interest. I wrote a Perl script that converts Firefox/Mozilla bookmarks (bookmarks.html) to a fvwm menu. The script is a bit quick and dirty and needs some cleanup and sanity checking, but does recreate the bookmark tree with any favicons included in bookmarks.html

This is awesome. Can’t wait to try it out. I have been wanting something exactly like this! Yea!

Lol I was yesterday messing around with dinamic menus and thought, amongst other things, of something similar to this… Seems that I can skip some work now (much less pain for me, since I know nothing about perl :smiley: )

Thanks for this, it worked out of the box in my config goes to make/find a bookmark.png :wink:

You might like this, I made it dinamical, so it gets updated (in other words, your script is run) each time you open the menu. This is done thru a function and the MissingSubMenuFunction command, so your bookmarks are always up to date.

DestroyFunc Bookmarks
AddToFunc Bookmarks
+ I DestroyMenu bookmarks_start
+ I AddToMenu bookmarks_start
+ I + DynamicPopDownAction DestroyMenu bookmarks_start
+ I PipeRead 'perl $[fvwm_scripts]/'
+ I Popup bookmarks_start

DestroyMenu menu_Root
AddToMenu   menu_Root
+ MissingSubmenuFunction					Bookmarks
........  <whatever>
+ %menu/bookmark.png%"Bookmarks"      	Popup bookmarks_start

Now im playing with the exports in opera, to see if I can make this work under it. Seems that opera only export bookmarks to html in a plain fashion (no tree, go figure what does that mean when you have a +40 nodes tree, with subtrees and lots of bookmarks into it…). If someone is more experienced with this crappy browser and knows anything that I might be missing just let me know :wink:

I thought about that. The favicons are created only once so this doesn’t add load, but the HTML-TreeParser is a resource hug.

No need to export. I’m not an opera expert, but it looks like opera stores “bookmarks” in ~/.opera/opera6.adr and the favicons in ~/.opera/images. Creating a new folder with one bookmark looks like


        NAME=Willkommen bei zeitform Internet Dienste - zeitform Internet Dienste
        DESCRIPTION=... bla bla ...


This looks parsable ("-" seems to be the end-of-folder maker).


Yes, I noticed :slight_smile: and dropped the missingsubmenufunction in less than a minute. You are right.

I know all that, but for some reason the menu does not display, I will dig a bit more and see if it is indeed an error parsion the thing or there is any other thing in the middle. Thanks for your response :wink:

EDIT: I think that what confuses the thing is the fact that I have somewhere in the middle a menu with more sublevels. From that afterwards all seems to appear messed and mixed in a weird manner. All the items are there, though…

I have not digged very deep, but I would try something like the following code fragment

### fragment
my $ID   = qr(\bID=([^\n]+)\n);
my $NAME = qr(\bNAME=([^\n]+)\n);
my $URL  = qr(\bURL=([^\n]+)\n);
my $ICON = qr(\bICONFILE=([^\n]+)\n);

$/=""; ## read in paragraph mode

my @ids = qw(start); ## stack for open folders

  if (/^#FOLDER\b.+$ID.+$NAME/s) ## hopefully opera keeps the order!
      my ($id, $name) = ($1, $2);
      push @ids, $id; ### "open folder"
      $menu{$ids[-1]} = menustart($ids[-1]); ### start menu with last id
      $menu{$ids[-2]} = menusubmenu($ids[-1], $name); ### add to last-but-one menu
  elsif (/^#URL\b.+$NAME.+$URL.+$ICON/s)
      my ($name,$url, $icon) = ($1, $2, $3);
      # generate icon
      $menu{$ids[-1]} = menuitem($name, $url, $icon); ## add to last menu
 elsif (/^-$/) 
      pop @ids; ### "close folder"

edit: added regexes

Thanks, it works, at least for now :wink:
