## Japanese Support Plugin for KOReader ##
|
||
|
|
|
||
|
|
This plugin is heavily based on Yomichan's design, and makes use of Yomichan's
|
||
|
|
deinflection data, but was written specifically for KOReader. There are two
|
||
|
|
major features implemented by this plugin:
|
||
|
|
|
||
|
|
1. Verb deinflection (aka deconjugation) support, based on Yomichan's very
|
||
|
|
elegant rule-matching suffix replacement system using Yomichan's data.
|
||
|
|
|
||
|
|
2. Text segmentation support without needing MeCab or any other binary helper,
|
||
|
|
by re-using the users' installed dictionaries to exhaustively try every
|
||
|
|
length of text and select the longest match which is present in the
|
||
|
|
dictionary. This is similar to how Yomichan does MeCab-less segmentation.
|
||
|
|
|
||
|
|
On paper this plugin should also be work with Chinese text if the user has
|
||
|
|
Chinese dictionaries installed, though that is not its primary intended
|
||
|
|
use-case.
|
||
|
|
|
||
|
|
The backbone of this plugin is the included `yomichan-deinflect.json`. This
|
||
|
|
file is copied verbatim from [Yomichan's `ext/data/deinflect.json`][yomichan-deinflect.json]
|
||
|
|
and can be updated when necessary by simply getting a newer copy.
|
||
|
|
|
||
|
|
Note that Yomichan and KOReader use the same license (GPL-3.0-or-later) so any
|
||
|
|
theoretical licensing problems are a non-issue.
