The following instructions describe ways of obtaining the current version of
the wiki. We do not yet cover importing the history of edits.

## Step 1: Getting a list of pages
The first bit of information you require is a list of pages in the Mediawiki.
Also, if you have pages with titles that need to be encoded to be represented
in HTML, you may need to add further processing to the last line.
+Note that by default, `Special:Allpages` will only list pages in the main
+namespace. You need to add a `&namespace=XX` argument to get pages in a
+different namespace. The following numbers correspond to common namespaces:
+
+ * 10 - templates (`Template:foo`)
+ * 14 - categories (`Category:bar`)
+
+Note that the page names obtained this way will not include any namespace
+specific prefix: e.g. `Category:` will be stripped off.

### Querying the database

+You need to create two derived strings from the page titles: the
destination path for the page and the source URL. Assuming `$pagename`
contains a pagename obtained above, and `$wiki` contains the URL to your
mediawiki's `index.php` file:
mkdir -p `dirname "$dest"`
wget -q "$wiki?title=$src&action=raw" -O "$dest"
+You may need to add more conversions here depending on the precise page titles
+used in your wiki.
+
+If you are trying to fetch pages from a different namespace to the default,
+you will need to prefix the page title with the relevant prefix, e.g.
+`Category:` for category pages. You probably don't want to prefix it to the
+output page, but you may want to vary the destination path (i.e. insert an
+extra directory component corresponding to your ikiwiki's `tagbase`).
+
### Method 2: via HTTP and `Special:Export`
Mediawiki also has a special page `Special:Export` which can be used to obtain

well-crafted queries.

+Mediawiki uses a special page name prefix to define "Categories", which

+into an ikiwiki tag name using a script such as
import sys, re

sys.stdout.write(re.sub(pattern, manglecat, line))
else: sys.stdout.write(line)

The [[plugins/contrib/mediawiki]] plugin can be used by ikiwiki to interpret
most of the Mediawiki syntax.
