You might be reading some out of date docs (e.g. for Rust 0.9) As of Rust 1.0, the way to escape { and } is with another { or } write!(f, “{{ hash:{}, subject: {} }}”, self.hash, self.subject) The literal characters { and } may be included in a string by preceding them with the … Read more
I think this could help you: import Foundation let timeNow = time(nil) let aStr = String(format: “%@%x”, “timeNow in hex: “, timeNow) print(aStr) Example result: timeNow in hex: 5cdc9c8d
>>> escaped_str=”One \\\”example\\\” >>> print escaped_str.encode(‘string_escape’) One \\\’example\\\’ >>> print escaped_str.decode(‘string_escape’) One ‘example’ Several similar codecs are available, such as rot13 and hex. The above is Python 2.x, but – since you said (below, in a comment) that you’re using Python 3.x – while it’s circumlocutious to decode a Unicode string object, it’s still possible. … Read more
varname=@(x) inputname(1); disp([‘Error in var: ‘ varname(mat)])
CString is specifically designed such that it only contains a pointer that points to the string data in a buffer class. When passed by value to printf it will be treated as a pointer when seeing the “%s” in the format string. It originally just happened to work with printf by chance, but this has … Read more
Since BindingBase.StringFormat is not a dependency property, I do not think that you can bind it. If the formatting string varies, I’m afraid you will have to resort to something like this <TextBlock Text=”{Binding MyFormattedProperty}” /> and do the formatting in your view model. Alternatively, you could use a MultiBinding and a converter (example code … Read more
No, you can’t apply slicing to strings inside a the replacement field. You’ll need to refer to the Format Specification Mini-Language; it defines what is possible. This mini language defines how you format the referenced value (the part after the : in the replacement field syntax).
You could use: String.format(“%-5s”, price ).replace(‘ ‘, ‘0’) Can I do this using only the format pattern? String.format uses Formatter.justify just like the String.printf method. From this post you will see that the output space is hard-coded, so using the String.replace is necessary.
There’s no way to do this using String interpolation. You can find a good discussion about this on this Apple Dev Forum post. You can use NSNumberFormatter or NSDateFormatter to format the output. Alternatively, to use printf-like syntax, you can still use NSString: var str = NSString(format: “Hello, world %.2f”, 42.12312312313)
This worked for me. String.Format(“{0:#,0} {1:#,0}”, 5, 5000); // 5 5,000
