fcitx5 使用自定义 lua 扩展输入当前日期和时间

fcitx5 使用自定义 lua 扩展输入当前日期和时间

fcitx5 输入法在输入特殊”字符“时，可以通过 extension 转换成预定义的内容。

fcitx5 内置了一个 pinyin.lua 脚本。这个脚本我没有仔细读，大致是实现了：

  • 输入 “日期”，候选列表 提供 [2023-07-21]，[2023年7月21日]，[二〇二三年七月二十一日]
  • 输入 “时间”，候选列表 提供 [15:52]，[15时52分]，[十五时五十三分]

现在我使用起来，希望能够提供“时分秒”的时间精度，所以从我们将 /usr/share/fcitx5/lua/imeapi/extensions/pinyin.lua 复制到 /home/suse/.local/share/fcitx5/lua/imeapi/extensions/pinyin.lua，然后修改用户目录下的脚本。下面是脚本变更的部分：
