I second the idea of the #include Discord. Welcoming and friendly, divided into channels so you can ignore things that are irrelevant to you, and chock-full of people who know a LOT and are willing to share it. Give it a try and if you find it falls short of your expectations I’d appreciate a private note with details so I can perhaps improve things.

Subject: Re: [SG20] OT: Mail list for learning C++

In the old days, I used to look at https://groups.google.com/forum/#!forum/comp.lang.c++ (except the google part, but that's where the group now has its home). More modern might be #include <c++> Discord<https://www.includecpp.org/> and r/cpp_questions<https://www.reddit.com/r/cpp_questions>,

Have a look there?

I know this is OT for this list, but I thought I'd ask here:

I'm looking for a mail list to help me learn C++, or at least certain aspects
of it. I've done some google searches, but just haven't found any.

Any suggestions?

Discussion:

A mail list suits my style much more than an IRC or forum. I have found
StackOverflow which I will try to use, but I'd much prefer a mail list.

Some background on what I need / what I'm trying to do.

I have programmed in quite a few languages, starting with things like Algol,
Fortran, with brief exposures to things like Lisp, APL, PL/1, and others I
can't recall atm during my education. In my career, I've written small
programs in various proprietary languages, "captive" languages (can't think of
the right word, but the languages built into things like dBase (3&4). I've
also written some fairly big programs in (Turbo ;-) Pascal.

Nowadays I use Linux and have written some scripts.

I left school before C was invented (or, at least, before it was published
anywhere), and just have never grokked C, and, even less, C++.

I now have a situation where I am (almost) forced to use C++. I want to write
a lexer for scintilla (a text editing "widgit" / control), which is written in
C++. I got some help from a student (in Serbia) who wrote something that does
some of what I need but has a bug, and, unfortunately, I've lost touch with
him. so I am trying to learn enough C++ to finish the lexer and find and fix the
bug.

(Aside: Some lexers have been written for scintilla in Lua, but (1) not all
editors which use scintilla support lexers written in Lua, and (2) Lua would
just be another new-to-me language that I'd have to learn. (And (3), I guess
I have concerns (perhaps not well founded) that it may be slower than a lexer
written in C++.)

Aside: scintilla originally limited itself to (iiuc) C++ version 11 or
earlier, but within the last year or so, the primary developer has started
using features of versions 14 and 17. (Another developer is trying to
maintain an LTS (long term support) version limiting it to C++ version 11
features.)

The lexer uses regex features of C++, and I have the impression that it uses a
more recent regex library than that in version 11.

Thanks for any suggestions.
