rime中州韵小狼毫 LaTex输入法配置

教程目录：rime中州韵小狼毫须鼠管安装配置教程保姆级教程 100+增强功能配置教程

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: 0states: [ 中文, 西文 ]- name: full_shape			# 字符默认半角输出reset: 0states: [ 半角, 全角 ]- name: ascii_punct			# 默认使用英文标点reset: 1states: [ 。，, ．， ]- name: debug					# 默认debug开关为关闭状态reset: 0states: [Off, 🐞]engine:processors:- ascii_composer- key_binder- speller- recognizer- punctuator- selector- navigator- express_editorsegmentors:- matcher- ascii_segmentor- abc_segmentor- punct_segmentor- fallback_segmentortranslators:- table_translator- punct_translatorfilters:- uniquifier
key_binder:import_preset: defaultspeller:auto_select: truedelimiter: " ;'"
recognizer:import_preset: defaultpatterns: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: latexversion: 0.2

translator:dictionary: latexspelling_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_translatorpunctuator:import_preset: symbolshalf_shape:"-": "-""|": "|""^": "^""]": "]""[": "["")": ")""(": "(""<": "<"">": ">"custom_phrase:encode_commit_history: falsedisable_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 simplifierkey_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 10recognizer/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") thenyield(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
