  • macOS と Android での音楽ライブラリーのカスタムソート順

    音楽ライブラリにおいてのカスタムソート順は、かなりまれなニーズだとされている。 ほとんどの主要言語は表音文字を使って、その自然な並べ替えが Unicode での順序とほぼ同じである(場合によっては正規化は必要)。一方、表意文字(主に漢字)を使う言語では、Unicode での並び方が自然な並び方(通常は読み順)と異なる。これにより、Unicode コードポイント順で並べ替えられたリストがおかしいな順番たと見られ、調べづらくなる。したがって、音楽ライブラリ中のタイトル、アーティスト、アルバム名などのカスタムソート順は、これら一つ、または複数の言語で構成している場合に役に立つ。

However, reST by now is still not popular enough. Most translation platforms, including Crowdin which I’m using now for EH Forwarder Bot, have no […]

    EH Forwarder Bot (EFB) is an extensible chat tunneling framework written in Python 3. GitHub.

    EFB is mainly designed for gathering messages from many other platforms to the one platform, but also designed with other types of tunneling in mind. In this article, I’d like to introduce how EFB works now, and how to design channels for group chat tunneling with utilizing available channels in EFB. Here “group chat tunneling” means synchronizing messages across several groups in different platforms.
