注意逃脱

Question

我正在尝试在Sublime中定义一个keybind，让它自动转换美元符号“$”，就像它自动发布以下符号一样：

“
（
[
{

我打开了默认的keymap文件并添加了以下代码：

// Auto-pair dollar signs
{ "keys": ["\$"], "command": "insert_snippet", "args": {"contents": "\$$0\$"}, "context":
    [
        { "key": "setting.auto_match_enabled", "operator": "equal", "operand": true },
        { "key": "selection_empty", "operator": "equal", "operand": true, "match_all": true },
        { "key": "following_text", "operator": "regex_contains", "operand": "^(?:\t| |\\)|]|\\}|>|$)", "match_all": true },
        { "key": "preceding_text", "operator": "not_regex_contains", "operand": "[\$a-zA-Z0-9_]$", "match_all": true },
        { "key": "eol_selector", "operator": "not_equal", "operand": "string.quoted.double", "match_all": true }
    ]
},
{ "keys": ["\$"], "command": "insert_snippet", "args": {"contents": "\$${0:$SELECTION}\$"}, "context":
    [
        { "key": "setting.auto_match_enabled", "operator": "equal", "operand": true },
        { "key": "selection_empty", "operator": "equal", "operand": false, "match_all": true }
    ]
},
{ "keys": ["\$"], "command": "move", "args": {"by": "characters", "forward": true}, "context":
    [
        { "key": "setting.auto_match_enabled", "operator": "equal", "operand": true },
        { "key": "selection_empty", "operator": "equal", "operand": true, "match_all": true },
        { "key": "following_text", "operator": "regex_contains", "operand": "^\$", "match_all": true }
    ]
},
{ "keys": ["backspace"], "command": "run_macro_file", "args": {"file": "Packages/Default/Delete Left Right.sublime-macro"}, "context":
    [
        { "key": "setting.auto_match_enabled", "operator": "equal", "operand": true },
        { "key": "selection_empty", "operator": "equal", "operand": true, "match_all": true },
        { "key": "preceding_text", "operator": "regex_contains", "operand": "\$$", "match_all": true },
        { "key": "following_text", "operator": "regex_contains", "operand": "^\$", "match_all": true }
    ]
},

注意逃脱的美元符号，\ $。在编辑器中，它们以红色突出显示，当我尝试保存文件时，出现无效的转义错误消息。逃避美元符号的正确方法是什么？

Answer 1

注意逃脱

你在这里经历两层编程。第一个Python，然后是JSON。因此，您逃脱的美元符号实际上需要两次转义：

"args": {"contents": "\\$$0\\$"}

Sublime Text读取设置文件后，Python将剥离第一个转义，留下以下JSON表示

"args": {"contents": "\$$0\$"}

然后，一旦解析了JSON，您最终将以

结束

"args": {"contents": "$$0$"}

不要逃避击键

您无需在$列表中转义keys。击键是一个字面的美元符号，因此不需要转义

以下是第一个设置的外观：

{ "keys": ["$"], "command": "insert_snippet", "args": {"contents": "\\$$0\\$"}, "context":
    [
        { "key": "setting.auto_match_enabled", "operator": "equal", "operand": true },
        { "key": "selection_empty", "operator": "equal", "operand": true, "match_all": true },
        { "key": "following_text", "operator": "regex_contains", "operand": "^(?:\t| |\\)|]|\\}|>|$)", "match_all": true },
        { "key": "preceding_text", "operator": "not_regex_contains", "operand": "[\\$a-zA-Z0-9_]$", "match_all": true },
        { "key": "eol_selector", "operator": "not_equal", "operand": "string.quoted.double", "match_all": true }
    ]
},
