1 This MoinMoin converter converts wikis to ikiwikis backed by a git repository, including full history. It simply parses the wiki pages into markdown using the MoinMoin engine.
3 The converter was originally written by [[JoshTriplett]] and included support for Tikiwiki, for which it parses the wiki pages to HTML then back into markdown using the `libhtml-wikiconverter` Perl package. That original version from Josh is still available from [his wiki page](/users/JoshTriplett).
5 The MoinMoin side of things was completely re-written by [[anarcat]] and is currently still in development. That version is available at:
7 git clone git://src.anarcat.ath.cx/moin2iki
9 It doesn't feature support to migrate from Tikiwiki anymore and focuses on MoinMoin support.
13 The software is made of two pieces:
15 * the importer (`moin2git`) - which converts the wiki pages into a git repository with full history
16 * the converter (`moin2mdwn`) - which converts a set of moin-formatted text files into markdown + ikiwiki directives
18 ## MoinMoin importer features
20 * supports latest MoinMoin versions (tested with 1.9.x)
21 * uses `git fast-import` to improve performance (10 minutes and 200M of ram for a 7 years old 2GB Moinmoin wiki)
22 * multistep process allows bulk edit through git before markdown conversion, or staying with a
23 * imports attachments as subpages
24 * uses the per-page edit log
25 * consistent: multiple runs will generate the same repository
26 * re-entrant: can be run multiple times to import new changes
28 ## MoinMoin converter features
30 * most of the inline markup
34 * images (not well tested), into [[ikiwiki/directive/img]]
35 * preformatted and code areas, including [[ikiwiki/directive/format]]
36 * ordered, unordered and definition lists
37 * tables (although only with HTML and no styles)
41 * TableOfContents, through [[ikiwiki/directive/toc]]
42 * Navigation, through [[ikiwiki/directive/map]] (so as a nested
43 vertical list instead of an horizontal list)
44 * PageList, through [[ikiwiki/directive/map]]
45 * MonthCalendar, partially, through [[ikiwiki/directive/calendar]]
46 * FootNote, through markdown
47 * Anchor, through markdown and plain HTML
48 * `<<BR>>`, through the weird line ending thing
49 * AttachList, through a weird [[ikiwiki/directive/inline]]
50 * FullSearch, partially, only through [[ikiwiki/directive/inline]] (so no textual search)
51 * Include, partially through [[ikiwiki/directive/inline]] (so missing boundary extraction and heading level generation)
52 * PageCount, same name even :)
53 * OrphanedPages, through [[ikiwiki/directive/oprhans]]
54 * Date and Datetime, should be through [[plugins/date]] instead of
59 * the main "moin wiki" markup
60 * highlight parser, through the [[plugins/format]] plugin
61 * other parsers may be supported if an equivalent plugin exists in Ikiwiki (example: [[plugin/rst]])
65 This script is being used to test the conversion of the venerable [Koumbit wiki](https://wiki.koumbit.net/) into Ikiwiki, and so far progress is steady but difficult. The current blocker is:
67 * figuring out exactly which pages should exist and which should not, as there is ambiguity in the internal datastructures of MoinMoin, which become apparent when running the conversion script, as files a missing
71 There are also significant pieces missing:
73 * inline parsers and hackish styled tables
74 * turn categories into tags
75 * name converted page to the right name depending on the `#format` parameter on top of page
76 * finish a full converter run on the Koumbitwiki
77 * improve the output of the converter (too much debugging)
79 ## MoinMoin features missing from ikiwiki
81 The importer is pretty much complete, but the converter can only go so far as what features ikiwiki supports. Here are the MoinMoin features that are known to be missing from ikiwiki. Note that some of those features are available in MoinMoin only through third-party extensions.
83 * [[todo/do_not_make_links_backwards/]] - MoinMoin and Creole use `\[[link|text]]`, while ikiwiki uses `\[[text|link]]` - for now the converter generates [[markdown]] links so this is not so much an issue, but will freak out users
84 * [[todo/internal_definition_list_support/]] - includes tabling the results ([MoinMoin's DictColumns macro](http://moinmo.in/MacroMarket/DictColumns))
85 * [[todo/per page ACLs]] - ([MoinMoin's ACLs](http://moinmo.in/HelpOnAccessControlLists))
86 * [MailTo](http://moinmo.in/HelpOnMacros/MailTo) macro spam protection
87 * list pages based on full text page search
88 * extract part of other pages with the inline macro
89 * specifying a template when creating a page (as opposed to matching a pagespec)
90 * specifying a style for a sub-section (MoinMoin's inline parsers
91 allow the user to specify a CSS class - very useful see
92 [the documentation](http://moinmo.in/HelpOnMoinWikiSyntax#Using_the_wiki_parser_with_css_classes)
94 * the above also keeps the SectionParser from being properly supported
95 * regex matching all over the place: pagespec, basically, but all
96 full text search (which is missing anyways, see above)
100 * RandomPage(N) - lists N random pages, skipped
101 * Gallery() - skipped
102 * Gettext - translates the string accordign to internal translation
104 * AdvancedSearch - an elaborate search form provided by MoinMoin
105 * Goto - a simple "jump to page" macro
