在Sublime Text中使用JSON配置文件中的注释会使JSON对象无法解码。这是我的故事。
我在我的Sublime Text 3中新安装了SublimeREPL插件。很快我发现它默认运行Python2.7而不是3.5,所以我根据SublimeREPL Docs添加了我自己的Python3.5配置文件,使其支持Python3 0.5。
我的Packages/SublimeREPL/config/Python3.5/Main.sublime-menu
JSON配置文件如下所示:
[
{
"id": "tools",
"children":
[{
"caption": "SublimeREPL",
"mnemonic": "R",
"id": "SublimeREPL",
"children":
[
{"caption": "Python3.5",
"id": "Python3.5",
"children":[
{"command": "repl_open",
"caption": "Python3.5",
"id": "repl_python3.5",
"mnemonic": "P",
"args": {
"type": "subprocess",
"encoding": "utf8",
"cmd": ["python3", "-i", "-u"],
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python3",
"extend_env": {"PYTHONIOENCODING": "utf-8"}
}
},
// run files
{"command": "repl_open",
"caption": "Python3.5 - RUN current file",
"id": "repl_python3.5_run",
"mnemonic": "R",
"args": {
"type": "subprocess",
"encoding": "utf8",
"cmd": ["python3", "-u", "$file_basename"],
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python3",
"extend_env": {"PYTHONIOENCODING": "utf-8"}
}
}
]}
]
}]
}]
请注意,此文件中有一条注释//运行文件。这个配置可以从菜单栏工具 - > SublimeREPL-> Python3.5中正常工作。但是,当我尝试使用repl_python3.5_run绑定F5键以便更轻松地访问3.5时,控制台中抛出了以下异常:
Traceback (most recent call last):
File "./python3.3/json/decoder.py", line 367, in raw_decode
StopIteration
During handling of the above exception, another exception occurred:

File "./python3.3/json/decoder.py", line 351, in decode
File "./python3.3/json/decoder.py", line 369, in raw_decode
ValueError: No JSON object could be decoded
删除//运行文件后注释。 F5键工作正常。这正是导致问题的注释。 Sublime Text使用JSON作为配置文件,许多配置文件带有//样式注释。我们知道,评论会从设计中删除。
那么sublime文本如何允许配置文件中的注释,是否使用管道?如果是,我的密钥绑定怎么会失败?
答案 0 :(得分:3)
Sublime本身(核心程序,而不是像SublimeREPL这样的插件)使用内部JSON库来解析配置文件,如.sublime-settings
,.sublime-menu
,.sublime-build
等。这(很可能是定制的) )解析器允许注释。
但是,插件是通过链接到Sublime plugin_host
可执行文件的Python版本(目前为开发版本为3.3.6)运行的。任何导入标准库的json
模块的插件(例如run_existing_command.py
)都必须遵守该模块的限制,包括无法识别JSON中的//
等JavaScript样式的注释。 / p>
对此的一种解决方法是导入一个外部模块,如commentjson
,在将数据传递到标准//
模块之前删除各种类型的注释,包括json
。由于它是纯Python模块,您可以将source目录复制到主SublimeREPL目录中,然后适当地编辑run_existing_command.py
- 将第6行更改为import commentjson as json
并且您已完成设置。
