I want to have a Chat-like simple UI where the chats can scroll & 2 buttons are at the end.

Currently, it looks like:

I recently received a request from an acquaintance to assist with building a C++ solution after their developer unfortunately passed away. I'm relatively new to C++ and don't quite understand what the following lines are doing.

This code is from a customized version of the dcraw.cpp library by Dave Coffin.

The MACRO is defined as

Hi folks thanks in advance for any help, I'm doing the CS50 course i'm at the very beginning of programming.

I'm trying to check if the string from the main function parameter string argv[] is indeed a number, I searched multiple ways. I found in another topic How can I check if a string has special characters in C++ effectively?, on the solution posted by the user Jerry Coffin:

I am trying to take an argument from a simple function "adder" and then use a loop to look at the effect of incrementing that argument.

I know there must be better approaches, such as building a single function that makes a longer data frame or maybe a nested loop without the second function... so I welcome those!

But what I'm more specifically interested is how to quote(?) and then parse(?) the argument, here called either "a" or "b" (but the function would declare them "arg_to_change") inside the new function, here called "change_of_adder_arguments".

I have a string formatted as:

GENESIS 1:1 In the beginning God created the heavens ... the ground. 2:7 And the LORD ... I buried Leah. 49:32 The purchase of the field and of the cave ... and he was put in a coffin in Egypt. EXODUS 1:1 Now these are the names ...

Using only one regular expression, I want to match as groups:

1. the book names
2. the chapter numbers (as above 1, 2, 49, 1)
3. the verse numbers (as above 1, 7, 32, 1)
4. the verses themselves
   • Take the first as example:

   (GENESIS)g1 (1)g2:(1)g3 (In the beginning God created the heavens ...)g4

This requires that I individually match everything within number-pair colons, while retaining my other groups, and with the limitation of fixed length lookaheads / lookbehinds. That last part specifically is what is proving difficult.

My expression up to now is (%(BOOK1)s) (\d+):(\d+)\s?(.+?)\s?(?=\d|%(BOOK2)s|$), where BOOK1 and BOOK2 change as they iterate through a predetermined list. $ appears because the very last book will not have a BOOK2 after it. I call re.finditer() on this expression over the whole string and then I iterate through the match object to produce my groups.

The functional part of my expression is currently (\d+):(\d+)\s?(.+?)\s?(?=\d|%(BOOK2)s|$), but by itself this in effect treats GENESIS as BOOK1 always, and matches everything from just after ^ to whatever BOOK2 may be.

Alternatively, keeping my full expression (%(BOOK1)s) (\d+):(\d+)\s?(.+?)\s?(?=\d|%(BOOK2)s|$) as is will only return the very first desired match.

I get the sense that some of my greedy / non-greedy terms are malformed, or that I could better use leading / trailing expressions. Any feedback will be highly appreciated.

this the continuation of me trying to make a recursive descent parser--LL(1)-- that takes in infix expressions and outputs RPN.
