<PrairieWind> I think I will just start learning c++ on w3schools |
| 02:25 |
MTDiscord |
<PrairieWind> Hmm, the semicolon requirement is going to be an interesting learning curve. |
| 02:26 |
muurkha |
I wouldn't recommend learning anything on W3Schools |
| 02:27 |
muurkha |
my girlfriend has found freecodecamp pretty great, but I'm not sure if they have a C++ module |
| 02:28 |
MTDiscord |
<PrairieWind> why not on w3schools? |
| 02:28 |
muurkha |
shitty site full of misinformation |
| 02:28 |
MTDiscord |
<PrairieWind> huh |
| 02:28 |
MTDiscord |
<PrairieWind> its been working for so far with cin and cout |
| 02:29 |
MTDiscord |
<PrairieWind> pretty interesting stuff |
| 02:29 |
muurkha |
when your program doesn't work you don't want to have to wonder whether it's because the tutorial you're following is wrong |
| 02:29 |
MTDiscord |
<PrairieWind> https://www.freecodecamp.org/news/learn-c-with-free-31-hour-course/ |
| 02:30 |
muurkha |
the outline sounds pretty reasonable |
| 02:31 |
muurkha |
may be a bit slow-paced if you already know how to program |
| 02:31 |
MTDiscord |
<PrairieWind> I can code lua |
| 02:31 |
MTDiscord |
<PrairieWind> and I found out geany builds and runs c++ fine for me |
| 02:32 |
muurkha |
you'll probably breeze through chapters 5, 6, and 7 then |
| 02:32 |
muurkha |
I think the "31 hours" is a bit misleading; that's the amount of video footage |
| 02:32 |
muurkha |
probably you'll need to spend several times that doing the exercises |
| 02:32 |
MTDiscord |
<PrairieWind> or playing around with the code on my own |
| 02:33 |
muurkha |
(I'm assuming there are exercises!) |
| 02:33 |
muurkha |
yeah |
| 02:33 |
MTDiscord |
<PrairieWind> I am playing around with cin and cout and variables |
| 02:33 |
MTDiscord |
<PrairieWind> pretty fun stuff for a basic calculator |
| 02:51 |

stream operators are overrated, printf works fine |

you dont learn C in 31h.... you can learn the syntax in 1 day but how to do things will take years |
| 06:50 |
muurkha |
not C, C++ |
| 06:50 |
muurkha |
nobody has ever learned the syntax of C++ |
| 06:51 |
muurkha |
I mean, yes, 30 years ago, but that was a much simpler language than what we call C++ today |
| 06:51 |
muurkha |
despite all that, you can totally do productive things in C++ within a few hours |
| 06:57 |
comrad |
the syntax of c++ is fixed as well and available after a few days. |
| 06:57 |
comrad |
the stl on the other hand - i still learn about new methods and classes |
| 06:58 |
comrad |
and compared to Java, C# and stuff the way to work with C++ feels very archaic |
| 06:59 |
comrad |
Split a String? Well, have fun with these iterators and npos and oh noes a template error! |
| 07:01 |
muurkha |
~, |
| 07:02 |
muurkha |
oops |
| 07:03 |
muurkha |
the syntax of C++ is not fixed; they just added a bunch of new crap to it in C++20 |
| 07:03 |
|

muurkha |
if you think you know it, it's only because you've never tried to write a C++ compiler |
| 07:03 |
comrad |
New Syntax? They've added some chrono-stuff and constexpr and stuff, what do you mean syntax specific? |
| 07:06 |
muurkha |
designated initializers, for example: T t { .p = 3, .q = 4 }; |
| 07:07 |
comrad |
oh those, yeah, i kind of try to avoid that |
| 07:07 |
comrad |
i once read that in order to work efficiently with c++ you should not try to use all the features ^^ |
| 07:07 |
comrad |
which is kinda the opposite of what every other language tells you |
| 07:08 |
muurkha |
lambda expressions with type parameters: []<class T>(T x, auto y) { return x + y; } |
| 07:10 |
muurkha |
bit field initializers: struct C { int f : 3 { 1 }; }; |
| 07:10 |
muurkha |
those three are new in C++20, but there's another dozen or so |
| 07:10 |
comrad |
please stop |
| 07:10 |
comrad |
this all looks weird |
| 07:10 |
muurkha |
it *is* weird! but that's not what's wrong with it |
| 07:12 |
muurkha |
there's a nice list at https://github.com/AnthonyCalandra/modern-cpp-features#c20-language-features |
| 07:14 |
muurkha |
C++ is a very expedient language for many purposes, but you should not expect to know its syntax. Even the standards-committee members don't |
| 07:14 |
comrad |
and its not implemented every the same, i had to work with MSVC, GCC and some proprietary rtos compiler. very tiny detailed differences... |
| 07:15 |
muurkha |
ugh, yes |
| 07:15 |
muurkha |
that's an excellent idea to stay away from new langauge features |
| 07:15 |
muurkha |
Rust has weird syntax too, and it's not a small language like C, but it's a relatively manageable language, not a monstrosity like C++ |
| 07:15 |
muurkha |
and maybe it will replace C++ at some point |
| 07:16 |
muurkha |
(for new code!) |
| 07:16 |
comrad |
we started a new project 2 years ago with C++ (instead of C) |
| 07:16 |
comrad |
with C++17 it was okay and nice, to some point at least |
| 07:36 |
Blockhead256[m] |
so is it really not possible to build minetestserver without install libjpeg, libpng, opengl etc. all that graphical stuff, just because irrlichtmt requires it? |

Blockhead256[m] |
never mind, apparently with the right cmake invocation to only build the server it skips irrlichtmt entirely? |

<PrairieWind> I was doing amusing stuff (at least imo) within an hour from reading and watching the video about c++ |
| 15:18 |
MTDiscord |
<PrairieWind> currently, I have a useless calculator that has 3 unused functions (-, x, /) and the addition and main function |
| 15:19 |
MTDiscord |
<PrairieWind> what I really want to learn is how to make it output a log to a text file, that would be fun. |
| 15:19 |
MTDiscord |
<PrairieWind> oh well, Im getting there. |
| 15:34 |

<luatic> dup2 |
| 15:39 |
muurkha |
dup2 is not especially helpful for that |
| 15:41 |
muurkha |
you can open an iostream on a text file, or you can open a cstdio FILE*, or you could open() a raw file descriptor, or use something more exotic like sfio or substdio |
| 15:41 |
MTDiscord |
<luatic> well, you can just redirect stdout to the text file |
| 15:42 |
MTDiscord |
<luatic> that said, if you want a log separate from stdout, of course dup2 won't help |
| 15:42 |
muurkha |
of these options I prefer cstdio but possibly that is because I am old |
| 15:42 |
MTDiscord |
<luatic> you could also redirect stderr though |
| 15:42 |
muurkha |
you could, yes |

about the pathfinding offered by API, I think the answer is no, but does it consider "climbable" nodes as valid ? |
