RIME_LaTeX

Typing LaTeX math symbols in RIME.

Press \ key then input latex symbol's name: \lambda will automatically become λ.

Use as standalone input method

Copy the latex.dict.yaml and latex.schema.yaml to rime's config folder.

Add those lines to default.custom.yaml

 patch:
  schema_list:
    - schema: latex

Use with other schemas

For instance, to use with 朙月拼音（简化字）, in luna_pinyin.custom.yaml (luna_pinyin_simp.custom.yaml)

# type '\' will pull in English punctuation, so need to switch to Chinese punctuation

    - name: ascii_punct # 
      states: [ ¥, $ ]
      reset: 0
# make '\' go into the candidate box
  speller/alphabet: zyxwvutsrqponmlkjihgfedcba\\
# or customize punctuator to make '\' go into the candidate box like below(please uncomment yourself)
#  punctuator/half_shape:
#    "\\": ["\\"]
#  punctuator/full_shape:
#    "\\": ["、", "＼"]

# meaning of the regex: ^ (start of line), \\(the starting \), .+(any char 1 or more time), $(end)
# first '\\' is recognized as a symbol(half_shape or full_shape). double '\\' make it to be recognized as a pattern
# translator's prefix will consume one '\\'. so user only type once '\' key, only recognize uppercase and lowercase letters, so you can use the number keys to select words.

    tips: "[LaTeX]"

Note: due to the complexity of mixing rime schemas, you may need extra efforts to mix RIME_LaTeX with arbitrary other schema.

RIME_LaTeX's extension to tex symbols

superscript/subscript

\^1 \_1 -> X₁¹
\^a \_b -> Xᵃᵦ

Unicode doesn't have a full set of super/sub scripts, you probably should use text styles or markup in rich text, instead.
