开发工具 怎样理解 SublimeText 关于括号的配置?
想交换圆括号和方括号的。打开配置看了半天看不懂.. 哪位大侠给讲解一下吗？
// Auto-pair square brackets
{ "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": "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 }
]
}
{ "keys": ["["], "command": "insert_snippet", "args": {"contents": "[$0]"}, "context":
那这个讲吧... 当下面 3 个条件满足时 按下"["的时候插入 snippet "[$0]"
{ "key": "setting.auto_match_enabled", "operator": "equal", "operand": true },
是说 setting.auto_match_enabled 这个要设定为 true
{ "key": "selection_empty", "operator": "equal", "operand": true, "match_all": true },
当前没有任何选中 (selection_empty)
{ "key": "following_text", "operator": "regex_contains", "operand": "^(?:\t| |\\)|]|;|\\}|$)", "match_all": true }
光标后面的内容要配到这个 regex
卤煮是想说按方括号的时候实际出圆括号？我不知道 sublime 能不能直接把一个键 map 到另一个 好像 key setting 里都是去触发 command 的
这里是文档 http://docs.sublimetext.info/en/latest/reference/key_bindings.html#
#2 楼 @leozwa 这么一说瞬间被大败了... Sublime 应该直接用 JS 代码写配置的 像楼上的解释的，下面的 JSON:
{ "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 }
]
}
实际上意思是，如果用伪代码表示结构才很清晰..
view.on '[', do
if setting.auto_match_enabled == true
if selection_empty == true and match_all
if following_text ~= "^(?:\t| |\\)|]|;|\\}|$)" and match_all
insert_snippet $0
这么想配置为什么有这么多的重复的 key 就明白了.. 我再看看
