The following instructions describe ways of obtaining the current version of
the wiki. We do not yet cover importing the history of edits.
+Another set of instructions and conversion tools (which imports the full history)
+can be found at <http://github.com/mithro/media2iki>

## Step 1: Getting a list of pages
The first bit of information you require is a list of pages in the Mediawiki.
you have tweaked your mediawiki theme a lot from the original, you will need
to adjust this script too:
+ import sys
from xml.dom.minidom import parse, parseString
- dom = parse(argv[1])
+ dom = parse(sys.argv[1])
tables = dom.getElementsByTagName("table")
pagetable = tables[-1]
anchors = pagetable.getElementsByTagName("a")
for a in anchors:
print a.firstChild.toxml().\
- replace('&,'&').\
+ replace('&','&').\
replace('<','<').\
replace('>','>')
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`)
+different namespace. (See below for the default list of namespaces)
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
If you have access to the relational database in which your mediawiki data is
-stored, it is possible to derive a list of page names from this.
+stored, it is possible to derive a list of page names from this. With mediawiki's
+MySQL backend, the page table is, appropriately enough, called `table`:
+
+ SELECT page_namespace, page_title FROM page;
+
+As with the previous method, you will need to do some filtering based on the
+namespace.
+
+### namespaces
+
+The list of default namespaces in mediawiki is available from <http://www.mediawiki.org/wiki/Manual:Namespace#Built-in_namespaces>. Here are reproduced the ones you are most likely to encounter if you are running a small mediawiki install for your own purposes:
+
+[[!table data="""
+Index | Name | Example
+0 | Main | Foo
+1 | Talk | Talk:Foo
+2 | User | User:Jon
+3 | User talk | User_talk:Jon
+6 | File | File:Barack_Obama_signature.svg
+10 | Template | Template:Prettytable
+14 | Category | Category:Pages_needing_review
+"""]]
## Step 2: fetching the page data
It is possible to extract the page data from the database with some
well-crafted queries.
-## Step 2: format conversion
+## Step 3: format conversion
The next step is to convert Mediawiki conventions into Ikiwiki ones.
pattern = r'\[\[Category:([^\]]+)\]\]'
def manglecat(mo):
- return '[[!tag %s]]' % mo.group(1).strip().replace(' ','_')
+ return '\[[!tag %s]]' % mo.group(1).strip().replace(' ','_')
for line in sys.stdin.readlines():
res = re.match(pattern, line)
sys.stdout.write(re.sub(pattern, manglecat, line))
else: sys.stdout.write(line)
-## Step 3: Mediawiki plugin
+## Step 4: Mediawiki plugin
The [[plugins/contrib/mediawiki]] plugin can be used by ikiwiki to interpret
most of the Mediawiki syntax.
-## External links
+The following things are not working:
+
+* templates
+* tables
+* spaces and other funky characters ("?") in page names
+
+## Scripts
[[sabr]] used to explain how to [import MediaWiki content into
git](http://u32.net/Mediawiki_Conversion/index.html?updated), including full
-edit history, but as of 2009/10/16 that site is not available.
+edit history, but as of 2009/10/16 that site is not available. A copy of the
+information found on this website is stored at <http://github.com/mithro/media2iki>.
+
+[[Albert]] wrote a ruby script to convert from mediawiki's database to ikiwiki at <https://github.com/docunext/mediawiki2gitikiwiki>
+
+[[Anarcat]] wrote a python script to convert from a mediawiki website to ikiwiki at <http://anarcat.ath.cx/software/mediawikigitdump.git/>. The script doesn't need any special access or privileges and communicates with the documented API (so it's a bit slower, but allows you to mirror sites you are not managing, like parts of Wikipedia). The script can also incrementally import new changes from a running site, through RecentChanges inspection. It also supports mithro's new Mediawiki2markdown converter.

I have fixed my script so it looks for media2iki directly in the submodule and improved the install instructions in the README file, but I'm not sure I can do much more short of starting to package the whole thing... --[[anarcat]]
