Sounds like a problem that someone else would have solved already. I’ve never used the module, but it looks useful: use String::Escape qw(unbackslash); my $s = unbackslash(‘hello\tworld\n’);
Your first form did work in the VS2015 Preview: int i = 42; var s = “\{i}”; That compiled and ran for me. ReSharper complained, but that’s a different matter. For the final release of C#, it is: var s = $”{i}”;
Escaping with a backslash(\) works for all characters except a curly brace. If you are trying to escape a curly brace ({ or }), you must use {{ or }} per $ – string interpolation (C# reference) … All occurrences of double curly braces (“{{“ and “}}”) are converted to a single curly brace.
You can apply both $ and @ prefixes to the same string: string s = $@”Result… Adding “”{x}”” and {this.Y()} to foobar: {x.GetLog()}”; When introduced in C# 6, interpolated verbatim strings had to start with the tokens $@, but starting with C# 8, you can use either $@ or @$.
(posted by Bill Hesse) By wrapping the string literal in a function that takes the context as a parameter, you can have a Function : context -> String that you can pass around instead of a String. If you need to use some String operations, like concat, on these objects, you can implement these operations … Read more
Unfortunately, you’re out of luck. To do what you want you’d need to pass in $home from a view file (or wherever) and interpolate it in your yaml entry, which could possibly look something like: Alice: ! ‘%{home}/Alice’ See this StackOverflow Q&A for the detailed answer to pretty much exactly your question.
See String.format method. String s = “hello %s!”; s = String.format(s, “world”); assertEquals(s, “hello world!”); // should be true
To complement marsze’s helpful answer: ${…} (enclosing the variable name in { and }) is indeed always necessary if a variable name contains special characters, such as spaces, ., or -. Not special are _ and – surprisingly and problematically – ?. Note: : is invariably interpreted as terminating a PowerShell drive reference, in the … Read more
The reason your current attempt doesn’t work is that single-quoted (‘) string literals in PowerShell are verbatim strings – no attempt will be made at expanding subexpression pipelines or variable expressions. If you want an expandable string literal without having to escape all the double-quotes (“) contained in the string itself, use a here-string: $mynumber … Read more
In order to delay string interpolation and perform it on demand, with then-current values, you must use $ExecutionContext.InvokeCommand.ExpandString()[1] on a single-quoted string that acts as a template: function HelloWorld { Param ($Greeting, $Name) $ExecutionContext.InvokeCommand.ExpandString($Greeting) } HelloWorld ‘Hello, $Name!’ ‘World’ # -> ‘Hello, World!’ Note how ‘Hello, $Name!’ is single-quoted to prevent instant expansion (interpolation).
