如何在用户输入时运行一个sublime plugin命令;或}

Question

我有一个崇高的插件，但我想，当用户键入一个}或;

我试图处理它在on_modified事件做一些事情，但我不能完全得到它的工作。

这是最好的方法吗？

添加与您的插件捆绑在一起的新键绑定。作为一个例子，这里是触发大括号的自动配对的默认键绑定：

{ "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 } 
    ] 
}, 
{ "keys": ["{"], "command": "wrap_block", "args": {"begin": "{", "end": "}"}, "context": 
    [ 
     { "key": "indented_block", "match_all": true }, 
     { "key": "setting.auto_match_enabled", "operator": "equal", "operand": true }, 
     { "key": "selection_empty", "operator": "equal", "operand": true, "match_all": true }, 
     { "key": "following_text", "operator": "regex_match", "operand": "^$", "match_all": true }, 
    ] 
}, 
{ "keys": ["{"], "command": "insert_snippet", "args": {"contents": "{${0:$SELECTION}}"}, "context": 
    [ 
     { "key": "setting.auto_match_enabled", "operator": "equal", "operand": true }, 
     { "key": "selection_empty", "operator": "equal", "operand": false, "match_all": true } 
    ] 
}, 

注意，通过使用单个字符作为键绑定，你拦截按键，它不会在显示缓冲。如果你想把字符发送到缓冲区，你需要把它放在那里作为你的命令的一部分。

您可以在示例中看到。这两个insert_snippet命令包裹的任何参数与大括号："contents": "{$0}"和wrap_block命令发送大括号的开始和结束ARGS："args": {"begin": "{", "end": "}"}
