Fcitx 5 and multiple wayland compositor

Actually there is nothing so special about this feature, it’s just come freely with the multiple X server support. I just realized that WAYLAND_SOCKET passed from compositor can be just sent via DBus to the actual fcitx5 server, without the … Continue reading

Fcitx 5 开发(三)如何调试输入法,先有鸡还是先有蛋

调试输入法,和写别的程序其实没有本质的区别,常见的办法也就是 GDB 和输出日志。但它特别的地方主要在于,你用来调试输入的程序也是输入法的客户端之一,在调试输入法的时候,如果不进行一些特别的操作,将会导致你调试用的终端 Freeze(把按键发送给了输入法,却因为程序 GDB 暂停无法获得响应导致 Freeze),也就是标题所说的先有鸡还是先有蛋的问题。 当然,要解决这个问题其实也简单,就是让你的终端不用输入法就行了。这里有几个点需要注意,常见桌面环境的终端一般是单实例,你即使启动一个新的窗口也是同一个进程,并不是重新启动一个进程。所以一般我个人会选择使用另外的终端程序。这是从终端程序禁止输入法方面来说。反过来,也可以通过命令行参数禁用 Fcitx 的前端。来阻止 Fcitx 和对应类型的程序进行通信。 先说说怎么启动一个无法使用输入法的终端。如果是 XIM 的终端,例如 xterm,alacritty,就直接用 XMODIFIERS=@im=none xterm 这样的方式启动,启动之后,在终端里面直接启动新的 fcitx 的话,就需要注意要在终端里面重新恢复 XMODIFIERS 的值为一般的值。因为根据 XMODIFIERS 的处理机制,Fcitx 会根据它启动时的 XMODIFIERS 设置对应的值。如果不进行设置的话,当前的这个终端自然也反而会可以和 Fcitx 通信了。如果是 Gtk 程序,可以设置 GTK_IM_MODULE=gtk-im-context-simple ,如果是 Qt 5程序,可以设置为 QT_IM_MODULE=compose 。 如果想要从 Fcitx … Continue reading
