'advancedBy' in Swift is unavailable
(2 answers)
Closed 5 years ago.
My project issue in screenshort.
enter image description here
You should just do what the error says and use index(_:at:offsetBy:):
original.insert("-", at: original.index(original.startIndex, offsetBy: 14))
In Swift 3 string handling methods have been renamed a little. advanceBy turned into this offsetBy instead.

Regex to match Date
(7 answers)
Closed 2 years ago.
I made a google forms which i asked a date of birth like dd/mm/yyyy.
I'm looking for a RegEx that allow every date from 01/01/1900 to 31/12/2015 but refuse every date who contains this 5 years 2016, 2017, 2018, 2019, 2020.
Does someone have an idea ?
Thanks for help.
If you really only want to check dates for years 1900-2015, it suffices to code
\b(\d{1,2}/\d{1,2}/(19\d{2}|200\d|201[0-5]))\b
The \b...\b bound is less restrictive than ^...$
Because the previous answer did not specify any year bounds, they need to be added, for example, 1900…2099 (excluding 2016-2020)
\b(?!2016|2017|2018|2019|2020)(\d{1,2}/\d{1,2}/(19|20)\d{2})\b

I am looking for a way to delete 9 characters after a string :
vimeo.com/600984066
I want to only have vimeo.com/ is there a way to do it with maybe regex ?
Important : I have some content after so i can't delete the 9 last characters of a line.
I found a solution using (?=vimeo\.com).{18}, hope that will help someone.

Strange //! comment syntax in Quick Controls 2.0 QML source [duplicate]
(2 answers)
Why are comments that start with "//!" colored blue in Qt Creator?
(2 answers)
Closed 6 years ago.
In "screenshot.cpp" of the Screenshot Example for Qt5.7, I saw around 15 comment-like lines of the form //! [int], like //! [0], //! [1], etc. They're syntax-highlighted differently than normal comments (highlighted blue instead of green in Qt Creator). I looked around and thought it might have something to do with the "!" mark in Qdoc, and thought it was unique in Qt, but when I tried typing it into Code::Blocks, it was syntax-highlighted differently too.
Does this syntax have any special meaning in C++? Or is it just a normal comment? I tried googling "c plus plus exclamation comment syntax" but I didn't get anything like this.
