Extended auto-linker (adds ed2k and sip link recognition)

Extended auto-linker 0.2
20051003 by mip

This plugin extends the auto-parse url option to recognize ed2k and sip (VoIP) links correctly.
ed2k file links are pretty-printed with the file name and a human-readable file size.

INSTALLATION:
Upload and activate plugin as usual.
If you want to automatically include a tag in a parsed ed2k link, you should uncomment line 67 (// $filenametag = ...) and set your desired tag.

NOTES:
This plugin uses (among other things) a slightly modified regex which allows "|" characters inside all auto-recognized URLs as required for ed2k links.

SCREENSHOTS:

Writing a post containing some ed2k and sip URIs. Auto-parse URL option must be on.


Preview of posting with recognized URLs.
Note the formatting of ed2k file urls with the human readable size.

First one to install, thank you!

God job, but if the ed2k link contain [ ] don?t work correctly :surprised:

is a minor bug, but it is possible to be solved?

tanks for the modification *installed

Didn't EDonkey shut down because of fileswapping? Does this technology now have a legal use then?

Legal_controversy

Under US law, "the Betamax decision" case holds that copying "technologies" are not inherently illegal, if substantial non-infringing use can be made of them. This decision, predating the widespread use of the Internet applies to most data networks, including peer-to-peer networks, since distribution of correctly licensed files can be performed. These non-infringing uses include sending open source software, public domain files and out of copyright works. Other jurisdictions tend to view the situation in somewhat similar ways.

legal or not legal? that is the question:ninja:

[Mastar]

Are they any options/settings for this?

[MRGTB]

Any chance you can port this over as a vB 3.0 hack?

[MRGTB]

I see this is still in the Beta stages. I hope you fix the square brackets "[]" problem as this hack is very promising.

I also think the option to add your own tag is a great idea, very cool indeed and that gives you the ability to advertise your site in the tag in links.

I have one sugestion though. Make the ed2k links so they open in the same browser window instead of a new browser window. By doing that you won't have to close a new browser window everytime to add a link from the board.

Also take a look here at this same ed2k code created for phpbb for some extra ideas that might prove useful. This hack has come a long way and is the best ed2k hack out there. I'm sure there is stuff in this below you can use.

## Author Notes: 
## If you have already installed a ed2k hack (which you mostlikely will have) 
## check the files mentioned below anyways and change it to this version of 
## the hack. This is very important to ensure it will work properly, otherwise 
## you might have weird problems. 
## Change the line below that looks like this to have a different text: 
## $t_ed2kinsert .= "<a href='javascript:addall()'>Add ".$t_ed2k_confirmed." links to ed2k client</a> "; 
## You can for example leave away the number of files.

Quick-note, to resolve the [ and ] problem, you just have to add quotes to the link parsed, so :
[*url=link]title[/url]
becomes
[*url="link"]title[/url]


I tried to modify the plugin, and now it does add the quotes, but the hack doesn't recognize the link as a link anymore

So, if I post a "normal" edk link (without [ or ]), it works, and adds the quotes, but if I post a link with [ in it, it doesn't parse it at all.

edit : Did some code search in the plugin, but regex are a little bit like chinese to me

just a thought, did you try using this instead.

[*url='link']title[/url]

single quotes instead of double to see if that works
