rime中州韵小狼毫 LaTex输入法配置
发布时间：2024年01月13日
本文的分享一种在rime中州韵小狼毫须鼠管输入法中配置LaTex输入方案的方法，并不完美，仅供参考。
先睹为快
LaTex输入方案可以快捷的在公式模式下输入一些基础的数学公式，选词快捷，录入体验优良。
latex.schema.yaml
latex.schema.yaml 是我们的输入方案的方案文档，我们在 用户文件夹 下创建一个 txt 文档，然后改名为 latex.schema.yaml,latex.schema.yaml文档内容如下👇：
switches:
- name: ascii_mode # 默认为中文输出模式
reset: 0
states: [ 中文, 西文 ]
- name: full_shape # 字符默认半角输出
reset: 0
states: [ 半角, 全角 ]
- name: ascii_punct # 默认使用英文标点
reset: 1
states: [ 。，, ．， ]
- name: debug # 默认debug开关为关闭状态
reset: 0
states: [Off, 🐞]
engine:
processors:
- ascii_composer
- key_binder
- speller
- recognizer
- punctuator
- selector
- navigator
- express_editor
segmentors:
- matcher
- ascii_segmentor
- abc_segmentor
- punct_segmentor
- fallback_segmentor
translators:
- table_translator
- punct_translator
filters:
- uniquifier
key_binder:
import_preset: default
speller:
auto_select: true
delimiter: " ;'"
recognizer:
import_preset: default
patterns:
email: "^[A-Za-z][-_.0-9A-Za-z]*@.*$"
url: "^(www[.]|https?:|ftp[.:]|mailto:|file:).*$|^[a-z]+[.].+$"
schema:
author:
- "dyy <douyaoyuan@126.com>"
description: "LaTex 公式输入"
name: "LaTex"
schema_id: latex
version: 0.2
speller:
alphabet: "zyxwvutsrqponmlkjihgfedcbaZYXWVUTSRQPONMLKJIHGFEDCBA_|\\/<>-+=^()[]{}<" # 定义输入字符的识别格式
delimiter: " "
translator:
dictionary: latex
spelling_hints: 9
在上述脚本配置中，我们的schema节点中配置了以下内容：
schema_id：latex；这个schema_id将会在下文的default.custom.yaml中用到name：LaTex；这个name的值LaTex将会出现在方案选单中
latex.custom.yaml
一如既往，方案名.custom.yaml是对应方案文档的补丁文档，这个latex.custom.yaml文档中配置了用户的个性化的配置项目，此处latex.custom.yaml文档的配置如下👇：
patch:
translator/enable_user_dict: false # false：自动造词及动态词频功能失效；true：启用自动造词和动态词频
style/inline_preedit: false # 是否在输入行内进行预测生成，true 表示不单独显示输入字符
engine/translators/+: # 增加以下翻译器
- lua_translator@latex_translator
- lua_translator@latexHelp_translator
punctuator:
import_preset: symbols
half_shape:
"-": "-"
"|": "|"
"^": "^"
"]": "]"
"[": "["
")": ")"
"(": "("
"<": "<"
">": ">"
custom_phrase:
encode_commit_history: false
disable_user_dict_for_patterns:
# - "^z.*$" # 这是原始默认设置
- "^[a-y]{1,3}$" # 三码及以下不使用自动调频、不自动造词
在以上配置中，我们为latex输入方案指定了以下关键配置：
- 翻译器
lua_translator@latex_translator：这个latex_translator的脚本文档将在下文中介绍。 - 翻译器
lua_translator@latexHelp_translator：这个latexHelp_translator的脚本文档将在下文中介绍。
latex.dict.yaml
latex.dict.yaml 是LaTex输入方案的字典文档,在该文档中我们定义了一些词组和按键的映射关系,latex.dict.yaml文档中的内容如下👇:
# Rime dictionary
# mim: set ts=8 sw=8 noet:
# encoding: utf-8
#
# latex - Latex
#
# dyy <douyaoyuan@126.com>
#
---
name: latex
version: "0.1"
sort: by_weight #defaut：使用字典文档顺序；by_weight：使用权重进行排序
use_preset_vocabulary: false
...
#关于词表定义及词序权重的说明
#词表定义格式如下：
#输出项 编码 权重
#关于权重，数字大者，其在候选框内出现的位置则靠前，如果没有指定权重值，则以词表定时次序排序
#常用组合
$$\textcolor{blue}{解：}$$ qev
$$\textcolor{blue}{证：}$$ ygh
👆上述字典中的内容很少,关于latex输入方案中的候选词组,更多需要依靠lua_translator生成,这我们下文中会有介绍.
default.custom.yaml
上文中我们定义了新的输入方案 latex，我们需要在 default.custom.yaml 中的方案选单中配置该输入方案，以便我们可以选择使用latex输入方案。default.custom.yaml中的配置如下👇：
patch:
ascii_composer/switch_key:
Caps_Lock: commit_code # 候选状态下，按 Caps_Lock 后编码上屏
Control_L: noop # 左 ctrl 键无使用效果
Control_R: noop # 右 ctrl 键无使用效果
Eisu_toggle: clear # 按 Esc 键，清除候选编码，退出候选框
Shift_L: commit_code # 候选状态下，按 左 Shift 后，编码上屏
Shift_R: commit_code # 候选状态下，按 右 Shift 后，编码上屏
ascii_composer:
good_old_caps_lock: true # true 通过 caps lock 键切换入英文模式后，保持大写输入状态
engine/filters:
- simplifier # 引入简体拼音输入法过滤器
- uniquifier # 过滤重复候选项，依赖 simplifier
key_binder/bindings:
- {accept: semicolon, send: 2, when: has_menu} # 使用 ; 键选择第 2 候选词
- {accept: apostrophe, send: 3, when: has_menu} # 使用 . 键选择第 3 候选词
- {accept: bracketleft, send: Page_Up, when: paging} # 使用 PageUp 键向上翻页
- {accept: bracketright, send: Page_Down, when: has_menu} # 使用 PageDown 键向下翻页
menu/page_size: 10 # 存在候选词选项时，每一页显示的候选词数量，最大是 10
recognizer/patterns/punct: "^/([0-9]0?|[A-Za-z]+)$" # 标点符号识别模式
schema_list:
- {schema: wubi_pinyin} # 五笔?拼音 输入方案
- {schema: easy_en} # 英文输入方案
- {schema: latex} # latex输入方案
- {schema: pinyin} # 拼音输入
switcher:
abbreviate_options: true # 功能选项显示为简写模式
caption: "〔方案选单〕" # 选项菜单的名字
fold_options: true # 功能选项折叠显示
hotkeys: [F8] # 使用 F8 键调出 方案选单
👆以上配置中，请注音观察schema_list节点下第三个schema的内容。
rime.lua
pinyin 输入方案中我们使用到了lua_translator和lua_filter，我们在rime.lua中增加一个translator翻译器和一个filter滤镜，rime.lua中的配置如下👇：
help_translator = require("help")
inputShow_translator = require("inputShow")
inputShow_Filter = require("inputShow_Filter")
Upper_Filter = require("Upper_Filter")
dic_4w_Filter = require("dic_4w_Filter")
phraseReplace_Filter = require("phraseReplace_Filter")
pinyinAdding_Filter = require("pinyinAdding_Filter")
dateTime_Filter = require("dateTime_filter")
dynamicPhrase_Filter = require("dynamicPhrase_Filter")
phraseExt_Filter = require("phraseExt_Filter")
phraseComment_Filter = require("phraseComment_Filter")
pinyin_translator = require("pinyin_translator")
pinyin_Filter = require("pinyin_Filter")
latexHelp_translator = require("latexHelp_translator")
latex_translator = require("latex_translator")
👆以上lua脚本中，注意观察最后两行内容。
💣注意：
以上所述default.custom.yaml、latex.custom.yaml、latex.schema.yaml、latex.dict.yaml、rime.lua 五个文档，应该位于 用户文件夹 下，如下👇：
latex_translator.lua
latex_translator.lua 是一个lua脚本，脚本实现了rime引擎的lua_translator翻译器接口；latex_translator.lua脚本实现了用户输入编码向latex词组翻译的功能。latex_translator.lua脚本内容如下👇：

以上 latex_translator.lua 脚本比较长，但这也仅实现了小部分的latex功能，后续慢慢再完善。
latexHelp_translator.lua
latexHelp_translator.lua是一个lua脚本定义的lua_translator翻译器。latexHelp_translator.lua所实现的功能比较简单，即在用户输入 help 字符时，将与latex输入方案有关的提示信息以候选词组的方式展示出来。latexHelp_translator.lua脚本的内容如下👇：
--lua语言中的注释用“--”
function translator(input, seg)
if (input == "help") then
yield(Candidate("help", seg.start, seg._end, "三角函数-->sin|cos|tan|cot|sec|csc", " "))
yield(Candidate("help", seg.start, seg._end, "反三角函数-->asin|acos|atan|acot", " "))
yield(Candidate("help", seg.start, seg._end, "双曲函数-->sh|ch|th|cth|sech|csch", " "))
yield(Candidate("help", seg.start, seg._end, "反双曲函数-->ash|ach|ath", " "))
yield(Candidate("help", seg.start, seg._end, "微分-->d?d?_", " "))
yield(Candidate("help", seg.start, seg._end, "积分-->intc|int", " "))
yield(Candidate("help", seg.start, seg._end, "对数-->log|lg|ln", " "))
yield(Candidate("help", seg.start, seg._end, "极限-->lim", " "))
yield(Candidate("help", seg.start, seg._end, "开方-->sqr", " "))
yield(Candidate("help", seg.start, seg._end, "上标-->?^", " "))
yield(Candidate("help", seg.start, seg._end, "下标-->?_", " "))
yield(Candidate("help", seg.start, seg._end, "线-->bar", " "))
yield(Candidate("help", seg.start, seg._end, "点-->dot", " "))
yield(Candidate("help", seg.start, seg._end, "临域-->mr", " "))
yield(Candidate("help", seg.start, seg._end, "R-->?n?", " "))
yield(Candidate("help", seg.start, seg._end, "颜色名称-->clr", " "))
yield(Candidate("help", seg.start, seg._end, "颜色文本-->tc|box", " "))
yield(Candidate("help", seg.start, seg._end, "特殊字符4-->alig|appr|arra|beca|canc|case|disp|doll|exis|fora|frac|grou|idxx|infi|line|matr|nexi|prod|suba|subs|sout|tria|ther", " "))
yield(Candidate("help", seg.start, seg._end, "特殊字符3-->big|gox|cap|cup|idx|max|min|neq|not|set|sim|sum|tau", " "))
yield(Candidate("help", seg.start, seg._end, "特殊字符2-->in|mp|ni|to|gt|ge|lt|le|", " "))
yield(Candidate("help", seg.start, seg._end, "希腊字符-->alph|beta|其它名称", " "))
--yield(Candidate("help", seg.start, seg._end, "-->", " "))
end
end

💣注意：
👆上述latex_translator.lua和latexHelp_translator.lua两个脚本文档，均应该位于 用户文件夹下的lua文件夹内，如下👇：
配置文档
👆以上所述配置文档，你可以在 rime中州韵小狼毫须鼠管输入法 LaTex输入方案配置包.zip 下载取用。
如果你可以访问gitHub，你也可以在 dyyRime 中找到完全版本的配置包。
效果欣赏
当你完成了以上的所有设置时，你需要重新部署你的rime，然后通过F4/F8调出方案选单，你应该可以看到LaTex输入方案，如下👇：
选择LaTex输入方案后，就可以愉快的开始体验LaTex输入公式了。
小结
本文分享了一中在rime中州韵小狼毫须鼠管输入法中配置LaTex输入方案的方法，从而实现了LaTex公式的快速录入，当前LaTex仅支持部分基础的公式录入,更多功能正在完善中。
