在 Sublime Text 的 Python 3 中使用 f 字符串完成引号

Question

当我在 Sublime Text 3 (3176) 中输入引号时，它会自动以右引号完成。

例如我输入" 我得到"<cursor>"

这很棒，我现在一直期待它。但是，如果我输入f"，将 f 字符串引入 Python，我会得到f"<cursor> 而不是f"<cursor>"。无论如何，这不是一个大问题，但它不像我认为的那样流畅。

如果光标左侧有字符，我认为自动完成规则不会添加额外的引号，因为这通常是在您尝试输入右引号时。

有没有办法修改规则，如果左边的字符是“f”，它会输入右引号？当您真正尝试以“f”结尾的字符串结束时，为了避免出现奇怪的用例，也许可以有一个and 条件来检查“f”左侧的左括号、空格或等号" 用于 print(f"string"、foo = f"string" 和 foo =f"string" 的高用例。

是的，这是可能的。只需将以下内容添加到您的用户键盘映射文件（首选项菜单 -> 键绑定。用户键盘映射是右侧的那个）：

// Auto-pair quotes even after string modifiers.
// Copied over from the default bindings with modifications to `preceding_text`
// and an added selector condition.
{ "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": "regex_contains", "operand": "(?i)\\b[bfru]+$", "match_all": true },
        { "key": "selector", "operator": "equal", "operand": "source.python" },
        { "key": "eol_selector", "operator": "not_equal", "operand": "string.quoted.double - punctuation.definition.string.end", "match_all": true }
    ]
},
{ "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": "regex_contains", "operand": "(?i)\\b[bfru]+$", "match_all": true },
        { "key": "selector", "operator": "equal", "operand": "source.python" },
        { "key": "eol_selector", "operator": "not_equal", "operand": "string.quoted.single - punctuation.definition.string.end", "match_all": true }
    ]
},

This will be shipped by default in a future build of ST.

它使用范围选择器来确定插入符号是否已经在字符串中，因此以f 字符结束字符串的情况不成问题。
