Ok, here is the code, if anyone is interested in. maybe it is a help for someone.
Since, the markdown-extra tables are not very comfortable to align and multiple head-lines are not supported, i will change my original idea and write my own html table and/or tab based template. also i’m not sure which data i will output. so, here is a sample output you will have to modifiy for yourself. at this stage, i think, every change will just help myself and not anyone else… so here are my findings/is my code.
- The Plugin analyses the raw content files for Markdown Links which are extended by a
tag: attribut.
- Original: (link: http://wikipedia.de text: wikipedia Website)
- New: (link: http://wikipedia.de tag: wiki text: wikipedia Website)
- when you use the new snippet tag in any of your pages, you will get a table of link collection.

some notes:
- links inside codeblocks or inline-code are ignored
- duplicate links are ignored
- invisible pages are ignored
- output is sorted by tag and by date
- when text attribute is empty, the hostname of the link is used as text
- tags are case-sensitive
- take a look at linksnippet.php to get an idea of outputcode
- i’m not a coder. those few lines of code cost me a lot of time. most of you will laugh on the ugly code, the ugly structure and time i wasted. i know, the most of you would write something like this is an hour or less. for me it took several full days of finding code snippets and trying to understand them.
- thx a lot to @texnixe for your help.
- also a lot help was the idea of this thread: Embedding Snippets
Include in site
possible output (with align-problem)
But don’t though, it confuses clients
