Rime 的希腊字母输入方案，也支持一些常用的数学符号。如果需要在其他输入方案中直接输入希腊字母，请参考：https://gist.github.com/lotem/3705586

我想在明月简体拼音输入方案中使用，但是按照链接中所说方法设置无效。我的luna_pinyin_simp.custom.yaml文件如下：

# luna_pinyin.custom.yaml
#
# 在【朙月拼音】裏使用Greek字符
#
# 保存到Rime用戶文件夾後，重新部署生效
# ~/.config/ibus/rime  (linux)
# ~/Library/Rime       (macos)
# %APPDATA%\Rime       (windows)
#
# 如果目標文件已經包含其他修改內容，只需按照縮進合併 patch: 以下的部分
#

patch:
  schema/dependencies:
    - greek
  abc_segmentor/extra_tags:
    - reverse_lookup
  reverse_lookup:
    dictionary: greek
    enable_completion: false
    prefix: "`"
    tips: 〔数学〕

@AlephAlpha 这样设置对吗？

@et2010 是我没写清楚。用简体拼音的话，还要加点别的东西，参看那个链接下面的评论。也就是改成这样：

# luna_pinyin_simp.custom.yaml

patch:
  engine/translators:
    - punct_translator
    - r10n_translator
    - reverse_lookup_translator
  recognizer/patterns/reverse_lookup: "`[a-z]*$"
  schema/dependencies:
    - greek
  abc_segmentor/extra_tags:
    - reverse_lookup
  reverse_lookup:
    dictionary: greek
    enable_completion: false
    prefix: "`"
    tips: 〔数学〕
