say i wanted to match a string to a regular expression, but i was only
given the string one character at a time.
one way to do this would be to evaluate the most recently submitted
character along with every previously submitted character, however,
that way seems like it would be unnecessarily inefficient.
another way i can see of doing this would be to have a function that
can access the previous state and return the state that the...

I am using match function of string to find if a character is there in a
string. The function Match is working fine with all the other characters

Hey guys,
I want to be able to insert a '-' character in front of all numeric
values in a string. I want to insert the '-' character to use in
conjunction with the getopt.getopt() function.
Rigt now, I'm implementing a menu system where users will be able to
select a set of options like "2a 3ab" which corresponds to menu
choices. However, with getopt.getopt(), it'll only return what I want
if I input -2a -3ab as my string. I don't...

Hi,
Quick question here, and wondering if anyone can help. I often see the hash character ('#') in regular expressions and am wondering what purpose it is supposed to serve.
Example:
#(?<=|^)
Every bit of online documentation I have looked at states the hash character's purpose is merely to denote the line is a comment. Clearly this is not the case if the regular expression is actually being used to test for something.
Can anyone...

Purpose
The purpose of this article is to discuss the difference between characters inside a character class and outside a character class and some special characters inside a character class. This is not a regular expression tutorial. Assumes you are already familiar with basic regular expression concepts and terminology. If not, you may want to read some regular expression tutorial. See the end of the article for links to online resources....

I'll be working with regular expressions and
hopeful as i am, i count on that there are
tools ready to handle e.g. file operations
using regular expressions.
Please tell me it's so and give me a pointer
to what classes/packages to aim at.

When I attempt to name a group in a regular expression under TR1, the
library throws a non descriptive error "regular expression error".
The numbered reference group works, as in /1 to reference the first
group. However, any attempt to use (?<myGroup>expression) fails?
Does anyone have any insight into this?
Thanks!

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
