[9fans] c++
I need to learn c++ for work - people have strong opinions on languages I know, and not everyone likes c++ but its a requirment for me. I really want to develop a good sence of c++ style, I learnt C at the feet of KR and then the plan9 sourcecode so I learnt how to write clean elegant code (I think :-). The problem I am finding is there are many c++ styles and I have yet to find a clean and elegant one. anyone sugest a project that I could look at that contains well written code? failing that is there a book that teaches good style? I am refering to things like adding a leading m_ to class member variables (which looks horrid to me but I am willing to learn), and smart locks (mutexs which unlock on destruct). Thanks for any suggestions. -Steve

Thanks, -Steve Hi you can find my apr port at: http://code.google.com/p/ports2plan9/ there is a binary download for i386, but I realized that it was broken during compilation of iconv so you are probably better off with a hg checkout. I have unfortunately not had much time playing with porting stuff to plan9 lately after I became a father in May. Got some fun ideas that I would like to explore though. anyone wanting to join or take over governance of above project is free to do so. also another warning: I am a total amateur (molecular biologist as a day job) so do not expect beatiful solutions ;)
Re: [9fans] c++
I would definitely use the new features of c++0x. Autos and Lambdas are the biggest noticeable change, so using them could be good style. Apparently the new constant expression offers optimisations from the compiler (probably equivalent to Java's final). Initialisation save's a couple of lines now. I'd also be interested in any books on the new threading part. Good luck.
Re: [9fans] c++
RE2 is very good code, but it doesn't contain any modern C++ features, and it's not written in standard style. That is part of what makes it good, I guess, but it might not help Steve. -- Aram Hăvărneanu

I think, one should use proper design regardless of program size; keep in mind that the small programs tend to become large programs. In my view this means adhering to the OO (object oriented) programming paradigm making full use of established design patterns. In essence this boils down to programming against interfaces (pure virtual classes in C++). The best books in the best practice category I've come across are: 1. C++ Coding Standards by Sutter and Alexandrescu, and 2. API design for C++ by Reddy. The best OO design pattern introductory book I come across unfortunately uses Java as model language but it's still worth reading for the insight, 3. Head First Design Patterns by Freeman Freeman. and a few of the must read books: 1. C++ Annotations by Frank B. Brokken http://www.icce.rug.nl/documents/cplusplus/ See also: 1. http://www.cplusplus.com/ The best projects in the best/clean coding style I've come across are: 1. http://yate.null.ro/ 2. http://qt.digia.com/ Hope that helps. -- Balwinder S bdheeman Dheeman (http://werc.homelinux.net/contact/)
Re: [9fans] c++
1. C++ Coding Standards by Sutter and Alexandrescu, and Haven't read this book, but I read Modern C++ Design by Alexandrescu, and it was one of the worst books on programming I have ever read, pretty much the antithesis of what we consider good in this group, so caveat emptor.

Re: [9fans] iwp9
Thanks to Erik for the compliments concerning iwp9 :-) I am glad you enjoyed the workshop and thank you for your comments throughout the workshop. As I like flying, I would actually consider flying into the local Athens Airport, IATA: AHN, ICAO: KAHN (IATA uses 3 letter codes - that is the codes used, e.g., on your baggage tags. All commercial airports have an IATA code. ICAO uses a 4 letter code, which is used to identify airfields, e.g., in flight plans. All airports and most smaller airfields have an ICAO code. Farm strips and often do not.) Pacific Wings has two daily flights between the local airport and Atlanta Hartsfield. -- Eric
Re: [9fans] c++
this is the problem. c++ programs follow a different definition of clean code than idiomatic c programs. by clean, they dont mean elegant or simple... it usualy boils down to lots and lots of structure, delegation and micro management and obsession with consistency and patterns. there will be proxy classes and visitor and mvc patterns and all that stuff and a c++ programmer will call it clean code because it follows constentent camel case naming and the funky patterms can be looked up in some book, tho its very hard to read or understand what the whole thing is even supposed todo with all that indirection and boiler plate. -- cinap PS: i think this is relevant: Sometimes, the elegant implementation is just a function. Not a method. Not a class. Not a framework. Just a function. -- John Carmack

Re: [9fans] c++
If i remember correctly void foo(); in C++ is equivalent to void foo(void) in C. And the type of 'x' (character literal) in C++ is char. Apart from that C++ is a superset of C. But i think it hardly helps him. In the end he will have to follow the conventions the others use. So I'd recommend reading the code you will work on. We use C++ too. And sadly it is hardly consistent since it is written by loads of people and noone bothers to check. But it's mostly readable. No template metaprogramming voodoo. Thankfully i work on some internal tools right now so i can get away with C and yacc. I'm even using plan9 right now to write documentation for one of them :) 2012/11/19 tlaro...@polynum.com It was not the question (since it is not a matter of taste but of professional need), but I find quite significant that nobody has cited a book of the author of the language as a good reading.

Re: [9fans] c++
Steve, A lot will depend on the target compiler and toolchain you'll be using. There's a big push in certain circles to go to Clang and C++11 n.tufnel Well, it's one louder, isn't it? It's not ten. You see, most blokes, you know, will be playing at ten. You're on ten here, all the way up, all the way up, all the way up, you're on ten on your guitar. Where can you go from there? Where? /n.tufnel though on the other hand there are a lot of groups trying to boost Boost. I don't recommend looking at the Boost implementation, it will make your compiler churn and your head spin. And then once you understand it a bit, you'll have to code tons of workarounds to slice out pieces of Boost. Google's protocol buffers source has a decent C++ implementation and should be a good example of writing relatively clean C++ code. Also take a look at (http://www.250bpm.com/blog:4) for a few pointers what not to do. -jas

[9fans] iwp9: lightweight nonhierachical navigation
Thanks for putting up the proceedings. The extension described in a light-weight non-hierarchical filesystem navigation extension paper sounds a bit like zsh's ** extension. In zsh a/**/b matches all existing paths with prefix a and suffix b, where a and b can be arbitrary subpaths. So for example wc sys/src/**/*.[ch] To wc all .c and .h files under sys/src. Zsh added many more extensions to pick files but ** is the most useful one.
