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)

patch:
# type '\' will pull in English punctuation, so need to switch to Chinese punctuation
  switches/+:
    - 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:
#    "\\": ["、", "\"]

  engine/translators:
    - punct_translator
    - table_translator
    - table_translator@latex_input
# meaning of the regex: ^ (start of line), \\(the starting \), .+(any char 1 or more time), $(end)
# first '\\' is recognized as a symbol(half_shape or full_shape). double '\\' make it to be recognized as a pattern
# translator's prefix will consume one '\\'. so user only type once '\' key
  "recognizer/patterns/latex_input": "^\\\\.+$"
  schema/dependencies/+:
    - latex
  latex_input:
    tag: latex_input
    dictionary: latex
    prefix: "\\"
    enable_sentence: false
    enable_completion: true # enable autocomplete
    enable_user_dict: true # enable word frequency,  use with user_dict
    user_dict: custom_latex_user # generate a file name custom_latex_user.txt
    db_class: tabledb
    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 schema's reference: https://github.com/LEOYoon-Tsaw/Rime_collections/blob/master/Rime_description.md

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.
