Good String Tokenizer

I have searched the board and noticed that there isn't really any sort
of good implementation of a string tokenizer that will tokenize based
on a custom set of tokens and return both the tokens and the parts
between the tokens.

For example, if I have the string:

"Hello, World! How are you?"

And my splitting points are comma, and exclamation point then I would
expect to get back.

["Hello", ",", " World", "!", " How are you?"]

Does anyone know of a tokenizer that will allow for this sort of use?

Thanks in advance,
Jim Howard

>>import re
re.split("([!,])", "Hello, World! How are you?")
['Hello', ',', ' World', '!', ' How are you?']

Here is what I want: string s1 = "This is a list of string"; list<string> s2 = s1.some_method(); Now, I should be able to traverse list s2 and get each member ( which is of type 'string' ). I know that this can be achieved using strtok. But I was wondering

This must be a classical topic -- C++ stgring tokenizer. I just switched from C to C++ ( in Unix ). It turns out that there is no existing C++ string tokenizer. Searching on the Web, I found several and tried one or two of them. Not very satisfied. Any suggestions? Thx!

Is it that I am blurry eyed, or is it indeed that the C++ string class has no tokenizer method defined? I have defined my own functions , but I would prefer to use the standard functions, if available. Thanks Bhat

I've used standard functions like find_first_of and find_first_not_of for some time. I was about to implement a quick string tokenizer similar to the example below when I ran across an old thread stating possible undefined behavior or possible portability issues with using std::string::npos I did not see a direct reason for the warning, and want to make sure I'm not setting my programs up for future failure by using npos. -- Are...

Hi, I'm trying to write a small code for an assignment which the void String Tokenizer will get a line input, and take out those delimiters from the original string. Then pass each string without the delimiters back to the struct. For an example: Line in is: Today, Friday 23, is a crazy day. Delimiters is: " ,." /*space, comma and period/* The stuct will get total of 7 words: "Today", "Friday", "23", "is" ..... "day". This is the codes...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
