DISQUS to Serendipity importer.
Fetch all the comments from your site using the Disqus API. Basically go into your admin area, go to the "Moderate" section and check the HTTP requests.
You should find something going to https://disqus.com/api/3.0/posts/list.
It will return a JSON structure. In the section cursor, there's a value
hasNext. If that's true, do the request again but add the parameter
cursor with the value from the next key to it. This will get you the
next bunch of comments. Rinse and repeat until you got everything.
Now copy all the files into the directory with these scripts and add
their names to the DISQUS_FILES variable in the Python scripts.
Also download your Serendipity SQLite database into the directory as serendipity.db.
Now run dump_urls_to_csv.py to create 2 CSV files. One is disqus2s9y.csv
which contains all the URLs from your DISQUS dump and an empty column
s9y_entry_id. The second file is s9y_urls.csv which contains all the
URLs from your Serendipity database.
The important step is now to match both, i.e. DISQUS-URL to Serendipity
entry_id. Fill in the matching entry_id into the s9y_entry_id column.
After you're done, run disqus2s9y.py and it should import all comments
into your serendipity.db. Afterwards copy that back to the server and
you're done.
