开发输入法是一种妥协的艺术
很久很久以前，我还没有在用 Linux 的那个时候，那会儿还在用 Windows 上的搜狗输入法。有时候经常就会好奇一件事，为什么输入法的更新日志里，经常会有「修复和XXX程序的兼容性」，「修复和YYY程序的兼容性」，难道他们不应该采用一套统一的接口吗？ 几年以后当我开始在 Linux 下开发输入法之后，我终于了解了一切…… 有些东西其实还是颇为为难的，我就来说一下曾经处理过的bug（有些解决，有些未解决，或者难以解决）。 1、LibreOffice 的 crash 简单来说原理就是在某个 Qt 调用 IM Module 的函数里调用某个函数可能会导致无限递归。这个相对来说是比较容易修复的，只需要把 IM Module 调用那个函数的移动到事件队列里延迟调用就可以避免递归了。但这个问题并不会在其他任何 Qt 程序中出现，相信也只是在某个 LibreOffice 的版本无意之中导致的。说实话这种问题并没有一种办法归结为是谁的“过错”，毕竟我相信相关的 API 并没有相应的文档来定义这么细节的调用是不合法的或者可能导致问题。 2、Gtk 的 Client Side Input Panel 的语言 tag 失效 Fcitx 5 有一个功能，让 Pango … Continue reading
