escaping

问题 I have a React app embedded in Wordpress page. It pulls content from a JSON api and displays it in various areas. My problem is that all of the text content that comes from the api displays as escaped charachters i.e & displays where an ampersand should be. My wordpress page has <meta charSet="utf-8" /> which I would normally expect to convert this, but is having no effecton the React content. Is it because the rendering is done within React? In which case do I need to set React somehow to be

问题 The following JSON object is valid: { "foo": "bar", "pattern": "^(\/?[-a-zA-Z0-9_.]+)+$" } Whereas this one is not : { "foo": "bar", "pattern": "^(\/?[-a-zA-Z0-9_.]+)+\.jpg$" } It's the escaped dot ( \. ), but I can't see why this should not be valid JSON. I need to include such patterns in my real JSON schemas. The regexp there are far more complex and there is no way missing out on excaping, especially the dot. BTW, escaping hypens in character classes such as in [a-z\-] breaks validation

问题 I'd like to create a snippet in VS Code, which includes exact string ${code} . However, when I enter it in this form, VS Code tries to interpret it as snippet parameter. How should I escape it properly? 回答1: "}" AND "$" can be escaped with "\\". Some cases "$" can be escaped with "$$" but not in your case. Your snippet should look like this. "Return Code With Squirly And Dollar": { "prefix": "code_snippet", "body" : [ "\\${code\\}" ], "description": "Code Snippet" } This should help you 来源：

问题 I want to do something like this: SQL.Text := Format('select foo from bar where baz like ''%s%''',[SearchTerm]); But Format doesn't like that last '%', of course. So how can I escape it? \% ? %% ? Or do I have to do this: SQL.Text := Format('select foo from bar where baz like ''%s''',[SearchTerm+'%']); ? 回答1: Use another % in the format string: SQL.Text := Format('select foo from bar where baz like ''%s%%''',[SearchTerm]); 回答2: %% , IIRC. 回答3: Obligatory: http://xkcd.com/327/ :-) Depending on

问题 Does anyone know how to escape colons in YAML?

问题 So there's a frame (main app). From here, I open a Modal JDialog and start a background thread working whilst displaying progress (log entries) in a table. This process is critical and should not be stoppable/hideable/closeable, thus why the dialog's close button is de-activated until everything's finished. However, the user can at any time tap the ESC key and my onCanceled() is called, thus calling this.dispose(). EDIT: I inherited this project and oversaw how deep the rabbit hole of

问题 For instance, I write a normal string and another "abnormal" string like this: Now I debug it, finding that in the debug tool, the "abnormal" string will be shown like this: Here's the question: Why does PyCharm show double backslashes instead of a single backslash? As is known to all, \' means ' . Is there any trick? 回答1: What I believe is happening is the ' in your c variable string needs to be escaped and PyCharm knows this at runtime, given you have surrounded the full string in " (You'll

问题 I've struggled for hours with this and although I found a solution, I don't like it. Is there a built in way to solve this: You are on Windows with a variable containing a path. You are trying to open a file with it, but it contains escape characters that you can't determine until runtime. If you use 'shutil' and do: shutil.copy(file_path, new_file_path) It works fine. But if you try and use the same path with: f = open(file_path, encoding="utf8") It doesn't work because the '\a' in the path
