Non-standard hyphenation

With luatex it is now possible to define non-standard hyphenation rules, like f-f → ff-f, repeated hyphen, ranked rules (or more exactly, “penalized”). No rules are currently provided by default (this is left for a later version), but they can be defined as shown in the following example:

    \babelposthyphenation{ngerman}{([fmtrp]) | {1}}
    {
      { no = {1}, pre = {1}{1}-}, % Replace first char with disc
      remove,                     % Remove automatic disc
      {}                          % Keep last char, untouched
    }

For a more detailed description and some examples, see Non-standard hyphenation with luatex.

Add and modify values from ini files

There is a way to modify the values of ini files when they get loaded with \babelprovide. To set, say, digits.native in the numbers section, use something like numbers/digits.native=abcdefghij (note the bar between the section and the key name). New keys may be added, too.

Changes in line breaking

Line breaking in South East Asian and CKJ are assimilated to hyphenation, and it is activated even without import (lua).
