Send a Text String Containing Double Quotes to Function

Send a text string containing double quotes to function

You can try these approaches:

foo <- function(numarg = 5, textarg = "** Default text **" ){ 
    cat(c(textarg, "\n")) 
    val <- (numarg^2) + numarg
    return(val) 
}

foo <- function(numarg = 5, textarg = "** Default text **" ){ 
    print(noquote(textarg)) 
    val <- (numarg^2) + numarg
    return(val) 
}

foo( 4, "Learning R is fun!" )
foo( 4, 'Learning "R" is fun!' )

How can I add double quotes to a string that is inside a variable?

You need to escape them by doubling them (verbatim string literal):

string str = @"""How to add doublequotes""";

Or with a normal string literal you escape them with a \:

string str = "\"How to add doublequotes\"";

Escape double quotes in a string

No.

Either use verbatim string literals as you have, or escape the " using backslash.

string test = "He said to me, \"Hello World\" . How are you?";

The string has not changed in either case - there is a single escaped " in it. This is just a way to tell C# that the character is part of the string and not a string terminator.

How to escape double quotes in JSON

Try this:

"maingame": {
  "day1": {
    "text1": "Tag 1",
     "text2": "Heute startet unsere Rundreise \" Example text\". Jeden Tag wird ein neues Reiseziel angesteuert bis wir.</strong> "
  }
}

(just one backslash (\) in front of quotes).

When should I use double or single quotes in JavaScript?

The most likely reason for use of single vs. double in different libraries is programmer preference and/or API consistency. Other than being consistent, use whichever best suits the string.

Using the other type of quote as a literal:

alert('Say "Hello"');
alert("Say 'Hello'");

This can get complicated:

alert("It's \"game\" time.");
alert('It\'s "game" time.');

Another option, new in ECMAScript 6, is template literals which use the backtick character:

alert(`Use "double" and 'single' quotes in the same string`);
alert(`Escape the \` back-tick character and the \${ dollar-brace sequence in a string`);

Template literals offer a clean syntax for: variable interpolation, multi-line strings, and more.

Note that JSON is formally specified to use double quotes, which may be worth considering depending on system requirements.

how to echo text containing with double quotes

You can use

echo 'text "hey"'

or

echo "text \"hey\""

In short:

• The double quote ( "quote" ) protects everything enclosed between two double quote marks except $, ', " and \. Use the double quotes when you want only variables and command substitution

  • Variable - Yes
  • Wildcards - No
  • Command substitution - yes

• The single quote ( 'quote' ) protects everything enclosed between two single quote marks. It is used to turn off the special meaning of all characters.

  • Variable - No
  • Wildcards - No
  • Command substitution - No

How to enter quotes in a Java string?

How to print double quotes inside ?

With a backslash before the double quote you want to insert in the String:

let sentence = "They said \"It's okay\", didn't they?"

Now sentence is:

They said "It's okay", didn't they?

It's called "escaping" a character: you're using its literal value, it will not be interpreted.

---

With Swift 4 you can alternatively choose to use the """ delimiter for literal text where there's no need to escape:

let sentence = """
They said "It's okay", didn't they?
Yes, "okay" is what they said.
"""

This gives:

They said "It's okay", didn't they?

Yes, "okay" is what they said.

---

With Swift 5 you can use enhanced delimiters:

String literals can now be expressed using enhanced delimiters. A string literal with one or more number signs (#) before the opening quote treats backslashes and double-quote characters as literal unless they’re followed by the same number of number signs. Use enhanced delimiters to avoid cluttering string literals that contain many double-quote or backslash characters with extra escapes.

Your string now can be represented as:

let sentence = #"They said "It's okay", didn't they?"#

And if you want add variable to your string you should also add # after backslash:

let sentence = #"My "homepage" is \#(url)"#
