How to print double quotes inside ""?
(3 answers)
Closed 2 years ago.
I have a really simple question and I bet the answer is as simple..
I want to create a String which include the symbol " twice, such as (Hello "" World !) or (Hello "new" World !), without breaking my String (for comprehension purpose, I've put my sentences inside of parentheses instead of said symbol ").
I can't remember the name of the symbol ("), so I can't google anything, because (" ") is not clear enough for searching motor..
I hope I'm being clear, thank you for your help !
You can use hashtag before and after the double quotes to allow any special character to be added inside your string:
let string = #"Hello "" World !"#

Original close reason(s) were not resolved
My code below match the first word after one expression "let" :
(?<=\blet\s)(\w+)
What I need is to match the first word after a specific expressions, "let", "var", "func"
Input text:
let name: String
var age: Int
func foo() {
//...
Expected:
name
age
foo
Here is an image for clarity:
Since some regex flavors do not allow using groups inside lookbehinds and alternatives of different length, it is safe to use a non-capturing group with the lookbehind as alternatives:
(?:(?<=\blet\s)|(?<=\bvar\s)|(?<=\bfunc\s))\w+
Here, (?:...|...|...) is a non-capturing group matching one of the three alternatives: (?<=\blet\s), (?<=\bvar\s) and (?<=\bfunc\s).

PowerShell outputting array items when interpolating within double quotes

Is a function call in a verbatim PowerShell string a thing?
CSharp example:
$"this my { GetSomeValue() }";
I would rather not extract a variable if I don't have to.
I always do it this way:
$verbatimString = 'something' + (GetSomeValue) + 'end'
Since it's verbatim string, you cannot do any trick, to put value directly into it, like you showed in your example.

I want to split a csv file. ex a row contain name,id,address,pin etc..... if the adress contains again commas then how to parse? ex: Abc,123,"xyz,asd,pqr",123456 "xyz,asd,pqr" is one element and kept in double quotes only
Use a CSV parser. If you don't want to install new modules for some reason then look at Text::ParseWords instead.

escape dictionary key double quotes when doing println dictionary item in Swift

This freaks out because it finds an unexpected " in the string interpolation:
let temp = "\(catalogueRows[0]["person"])"
Tried using single quotes but that didn't work. Seems like a pretty simple step and I'm confused why it doesn't work.
You can't use quotes in a string interpolation. That's just the way the syntax is.
You can't "escape" or single-quote your way out. You'll need two lines of code to do what you're trying to do:
let temptemp = catalogueRows[0]["person"]
let temp = "\(temptemp)"
