+`ikiwiki-transition` aids in converting wiki pages when there's a major
+change in ikiwiki syntax. It also handles other transitions not involving
+wiki pages.
-# prefix_directives
+# prefix_directives your.setup
-The `prefix_directives` mode converts the specified ikiwiki page from
-the old preprocessor directive syntax, requiring a space, to the new
-syntax, prefixed by '!'.
+The `prefix_directives` mode converts all pages from the old preprocessor
+directive syntax, requiring a space, to the new syntax, prefixed by '!'.
Preprocessor directives which already use the new syntax will remain
unchanged.
-Note that if the page contains wiki links with spaces, which some
+Note that if a page contains wiki links with spaces, which some
older versions of ikiwiki accepted, the prefix_directives transition will
treat these as preprocessor directives and convert them.
-# setupformat
+# setupformat your.setup
The `setupformat` mode converts a setup file from using a single `wrappers` block
to using `cgi_wrapper`, `git_wrapper`, etc.
Note that all comments and any unusual stuff like perl code in the setup
file will be lost, as it is entirely rewritten by the transition.
-# aggregateinternal
+# aggregateinternal your.setup
The `aggregateinternal` mode moves pages aggregated by the aggregate plugin
so that the `aggregateinternal` option can be enabled.
-# indexdb
+# moveprefs your.setup
+
+Moves values that used to be admin preferences into the setup file.
+
+Note that all comments and any unusual stuff like perl code in the setup
+file will be lost, as it is entirely rewritten by the move.
+
+# indexdb your.setup|srcdir
The `indexdb` mode handles converting a plain text `.ikiwiki/index` file to
-a binary `.ikiwiki/indexdb`. In this mode, you should specify the srcdir of
-the wiki as the second parameter. You do not normally need to run
+a binary `.ikiwiki/indexdb`. You do not normally need to run
`ikiwiki-transition indexdb`; ikiwiki will automatically run it as
necessary.
-# hashpassword
+# hashpassword your.setup|srcdir
The `hashpassword` mode forces any plaintext passwords stored in the
`.ikiwiki/userdb` file to be replaced with password hashes. (The
-Authen::Passphrase perl module is needed to do this.) In this mode, you
-should specify the srcdir of the wiki as the second parameter.
+Authen::Passphrase perl module is needed to do this.)
If this is not done explicitly, a user's plaintext password will be
automatically converted to a hash when a user logs in for the first time
after upgrade to ikiwiki 2.48.
+# deduplinks your.setup
+
+In the past, bugs in ikiwiki have allowed duplicate link information
+to be stored in its indexdb. This mode removes such duplicate information,
+which may speed up wikis afflicted by it. Note that rebuilding the wiki
+will have the same effect.
