不同范围的不同键盘映射

对于 Sublime 文本中使用的 LaTeXTools 包，如何定义相同的快捷方式以对两个不同的LaTeX文档类进行不同的操作？

例如，假设您想在键盘映射中定义“control+enter”以便对 BEAMER 进行以下操作：

// new equation line (LHS + RHS)
{ "keys": ["control+enter"], "command": "insert_snippet", "args": {"contents": "\n\\uncover<+->{$1} &   \\uncover<.->{=$2}  \\\\\\\\$0"}, 
"context":  
    [
        {"key": "selector", "operator": "equal", "operand": "text.tex.latex string.other.math, text.tex.latex meta.environment.math"},
        { "key": "setting.auto_match_enabled", "operator": "equal", "operand": true },
        { "key": "selection_empty", "operator": "equal", "operand": true, "match_all": true }
    ]
},

但随后必须"control+enter"按照以下方式对文章进行操作

// new equation line (LHS + RHS)
{ "keys": ["control+enter"], "command": "insert_snippet", "args": {"contents": "\n$1    &   =$2 \\\\\\\\$0"}, 
"context":  
    [
        {"key": "selector", "operator": "equal", "operand": "text.tex.latex string.other.math, text.tex.latex meta.environment.math"},
        { "key": "setting.auto_match_enabled", "operator": "equal", "operand": true },
        { "key": "selection_empty", "operator": "equal", "operand": true, "match_all": true }
    ]
},

也就是说，"control+enter"为 beamer 包裹了一个带有揭露覆盖的对齐环境，但对于 article 文档类则没有。

你会怎么做？

"operand"在每种情况下您需要如何定义（或范围）？

您无法使用内置范围执行此操作，但需要上下文。我将添加下一个预发布（即st3-4.0.0-alpha.3）通过LaTeX工具#1167。如果您有该预发行版，您只需添加键绑定：

{ 
    "keys": ["ctrl+enter"], "command": "insert_snippet", "args": {"contents": "\n$1    &   =$2 \\\\\\\\$0"}, 
    "context":  
    [
        { "key": "selector", "operand": "text.tex.latex meta.environment.math" },
        { "key": "selection_empty", "operator": "equal", "operand": true, "match_all": true }
    ]
},
{ 
    "keys": ["ctrl+enter"], "command": "insert_snippet", "args": {"contents": "\n\\uncover<+->{$1} &   \\uncover<.->{=$2}  \\\\\\\\$0"}, 
    "context":  
    [
        { "key": "selector", "operand": "text.tex.latex meta.environment.math" },
        { "key": "selection_empty", "operator": "equal", "operand": true, "match_all": true },
        { "key": "latextools.documentclass", "operand": "beamer" }
    ]
},

在发布之前，您可以通过以下方式手动安装

  1. 下载文件这里
  2. 打开 LaTeXTools 文件夹：在菜单中选择首选项 > 浏览包...然后打开 LaTeXTools 文件夹
  3. 将下载的文件放在那里

要模拟代码片段，请安装“Chain Of Command”并创建以下键绑定：

{
    "keys": ["tab"],
    "command": "chain",
    "args": {"commands": [
        ["delete_word", {"forward": false}],
        ["insert_snippet", {"contents": "\\mybox<..>"}],
    ]},
    "context":
    [
        { "key": "auto_complete_visible", "operand": false },
        { "key": "preceding_text", "operator": "regex_contains", "operand": "\\bbox$", "match_all": true },  // <- change "box" here
        { "key": "selector", "operand": "text.tex.latex meta.environment.math" },
        { "key": "selection_empty", "operator": "equal", "operand": true, "match_all": true },
        { "key": "latextools.documentclass", "operand": "beamer" },
    ]
},
