yabs: Yet Another Build System, seeking input/micro-team member
by degski 03 Mar '20

03 Mar '20

Hi All, Recently, I have started to get more and more dis-enchanted with Windows. The OS is being dumbed down every step of the way, while the internal complexity keeps going up. The latest and the most fun break-down to date of Windows was last week, the story is long, but in the end in came down to not being able to open the system-settings in the W10-style settings. The W7-style settings are also available, but the API's are overlapping but neither is a super-set of the other, so no way to fix the settings, because the settings themselves are broken (had something to do with display-drivers), way to go MS. In the meanwhile W10 is sorted again, but the whole lot is just getting increasingly fragile, while Fedora is getting increasingly solid (no bt-headphone stuttering, while connected to wifi and look at that brightness/crispness of that Full HD screen I have never seen before under W10!), the latter not upping complexity (2'001 packages to download and install to get from F30 to F31, but that's not complexity). I want to move to Fedora, and for now I'm dual-booting. This involves dumping VS in favor of VSCode (which is flat-packed for Fedora and compadres and is also available on OSX, so there is potentially a large audience), no acceptable other options (other than the one(s) VSCode is based on) are available AFAIKS, gnome-builder seems to have different goals from VS and it appears to be early days. VSCode seems (to me) to be like the best thing since sliced-bread, iff you are writing Python or Rust (Prolog works nicely as well), but C++ is only partially great, the language server works very nicely, code completion, good, but the build-system, proposed, is cumbersome. I would like VSCode to work more like VS, but without the complexity, the endless clicking, drop-down boxes etc etc. It comes down to writing json-files, which is good, but on a per project basis. Having to do this on a per project basis is a problem (that's going backwards from using project-templates in VS, I now in VS can create a new project in 3 seconds flat, and every detailed setting (clang and vc) is set correctly and how **I** want it, and I am running "Hello World!" (the default main in the template) in total 10 secs, this very handy to try things out). I don't want to go backwards. Therefore, I would like to do this on a repo-basis (the only one I have), with, iff required, another json in the project-folder (in the parent repo-folder), i.e.: /repos/ /repos/repo.json /repos/project-one/ /repos/project-one/project.json /repos/project-two/ /repos/project-two/project.json /repos/ ... I (want to) use vcpkg. I structure my projects always the same, all build systems (to my purpose) are basically an over-shoot on the one hand and overly fiddly on the other hand. The task at hand, build the .cpp files in the root of the project folder into one binary. The include files are either in the vcpkg/installed/.../include folder or in a sub-include-folder in the project. Libraries to link are either in vcpkg/installed/.../lib, or vcpkg/installed/.../debug/lib. We are not talking rocket-science here, I presume that many people have simple needs like this/me, or that if building (adopting this structure) becomes easy enough people would adopt such a structure. I would like to have one json to rule them all, and one json to either over-ride the defaults, or to add to the defaults, depending on whether the setting is defined in the repo.json. The repo.json might well be layered itself, to accommodate the various compilers, and/or configuration. For the moment nlohman's json seems perfectly adequate for the job, and it's certainly easy to use (and seems to just use std::maps in a clever way, so it's easy to follow what's going on). It's all about merging, fusing, overlaying those json's as needed (gonna be entertaining, making it smart), and pass that on to some generic API for building. So a new compiler would mean to just add a json-section, or a json-file, fill that with appropriate data (possibly nothing, iff the default-defaults are good), and it should work. The current way VSCode is setup, means that this imaginary build-system can be easily and readily included/used in VSCode (with more json). Yes, just like the working name indicates YABS, it must be as simple as possible, but no simpler. Any input is appreciated, but please refrain from arguing that BS-X does this better (and exists) or BS-Y has a large crowd of followers (and is used for a long period of time), that's water under the bridge, I will pursue this, just to see how far one can get pushing these initial ideas further. As usual my write-ups are a bit messy, I am learning I'm slightly dyslexic, sorry for the endless comma's. Thanks in advance for any ideas submitted. I would not mind partnering with somebody else, ya'll have a nice day, degski -- @systemdeg "We value your privacy, click here!"

So now you need a cast to shut the thing up, and I would write: for ( int i = 0, back = static_cast<int> ( obj.size ( ) ) - 1; i < back; ++i ). I would like: for ( int i = 0, back = obj.size ( ) - 1; i < back; ++i ). This is my last post on the subject (bar new arguments).

Boost.StaticString (formerly Boost.FixedString) is ready for release!
by Krystian Stasiowski 02 Mar '20

02 Mar '20

Hi all, After some post-review polishing, Boost.StaticString is good to go for release! I have been in touch with the review manager, and everything has been checked over. Repo: https://github.com/sdkrystian/static_string Docs: https://sdkrystian.github.io/doc/static_string Here are some things that have been changed post-review: - Library has been renamed from Boost.FixedString to Boost.StaticString. Class template fixed_string has been renamed to basic_static_string, and aliases have been added for common character types, similar to std::string. - constexpr support to the fullest extent supported by available compilers has been added. - Functions that will not throw have been marked noexcept. - Moved to a single header configuration. - std::hash and boost::hash_value support has been added. - It has been decided that functions will throw on capacity overflow. - A specialization for when the capacity is 0 has been added that has no member. Additionally, the type of the member used to store the size of the string is now statically chosen to be the smallest possible width unsigned standard integer type that can hold all the needed size values. - operator+ has been implemented. - Floating point conversion support has been added to to_static_string/to_static_wstring. - Lots of bugs fixed. More behind the scenes, a bunch of optimizations have been added, taking advantage of the fact that the capacity is part of the type and known at compile time. Again, thank you all who participated in the review, and thank you Joaquin for managing it! Regards, Krystian Stasiowski

Projects for GSoC 2020
by David Bellot 01 Mar '20

01 Mar '20

Hi Boost community, so far we received a few good contributions for projects for GSoC 2020. The proposals are from our usual mentors but I'm surprised we don't have more projects in data structures and algorithms. Most of what we have concern numerical problems. It's great but I wish to see more diversity in the type of projects we propose. We want to attract the best students around the world and push toward new C++ standards and improvements of what we already have. Being a mentor is a great experience and on top of it, without too much effort, you will get someone of quality working for you during all the summer. The wiki page for projects is here: https://github.com/boostorg/wiki/wiki/Google-Summer-of-Code%3A-2020 Please come, edit and contribute. Cheers, David

What is the right way to close and clean boost::log
by JH 01 Mar '20

01 Mar '20

Hi, I built boost::log in my application library, it created boost::log::sinks::synchronous_sink<boost::log::sinks::text_file_backend> and close it by calling the boost::log::core::get()->remove_all_sinks() in destructor of the Log library, then one of my application link to my log library got Segmentation fault when it exited: Program received signal SIGSEGV, Segmentation fault. 0x00007ffff5fdd961 in boost::log::v2_mt_posix::core::remove_all_sinks() () from /usr/lib/x86_64-linux-gnu/libboost_log.so.1.65.1 If I add boost::log::core::get()->remove_all_sinks() in my application main before it return 0, the segmentation was gong, but it stuck. What is the proper right way to close and clean the boost::log? There is a blog suggested to run boost::log::core::get()->remove_all_sinks() when the main end, but that does not seem work. https://www.boost.org/doc/libs/1_62_0/libs/log/doc/html/log/rationale/why_c… Thank you.

Cryptography for Boost.
by Mikhail Komarov 29 Feb '20

29 Feb '20

Hello! Cryptography for Boost. Again. It’s been some time since I’ve started developing so-called clean C++ cryptography implementation for my organization’s internal purposes. It was intended at first to be a cryptography framework fulfilling special cryptography schemes requirements, but eventually it has evolved into a full-featured suite, actively using and, sometimes, even based on Boost libraries. This turned out to be fine way to serve the Boost (and entire C++) community and to assemble a Boost version of a suite. So this letter is about wether there is still any interest in cryptography library for Boost and is there any sense to show the community what do I have for now? Sincerely yours, Mikhail Komarov nemo(a)nil.foundation

[gsoc] Encourage original ideas
by Mateusz Loskot 29 Feb '20

29 Feb '20

Hi, I noticed there may be confusion among students regarding project ideas. I sense, students (sometimes) fail to find the GSoC guides [1] ... So, based on the first paragraph of [1], I have updated our wiki [2] placing this note to students: "To any potential students, in addition to the list of project ideas, we don't discourage original ideas proposed by students. " If any mentors here disagree, please let me know and I will remove it (or move it to GIL, which I'm involved with as a mentor).

Who's using Boost
by Adam Getchell 28 Feb '20

28 Feb '20

Name: CDT-plusplus [1] Company: University of California Davis CDT-plusplus generates ensembles of quantum spacetimes under the Causal Dynamical Triangulations program using the Metropolis-Hastings algorithm, with other algorithms planned. These ensembles allow calculations of quantities such as the spectral dimension and the overall transition amplitudes from the beginning until the end of time for a simulated universe of given dimension and volume. Many different research problems may be answered with these ensembles, including the existence of a Newtonian limit in CDT [2], renormalization group flow in CDT, [3] and spontaneous dimensional reduction in short distance quantum gravity. [4] Where Boost is used: 82 Boost libraries are used in conjunction with CGAL [5] in order to perform accurate geometric and combinatoric operations on 3 and 4-dimensional Delaunay triangulations. Boost.Optional and Boost.Outcome are used to assist in correctness guarantees for billions of moves permuting triangulations on simulations running for months on High Performance Compute clusters.

So the available open source email libraries tend to be *nix-oriented and have to be built with a ported *nix toolchain.

[GSoC] My piece of advice to students
by Mateusz Loskot 24 Feb '20

24 Feb '20

Dear Student, You are planning to participate in GSoC and develop some new features for the Boost libraries. Awesome! So, you want to introduce yourself to the community as soon as possible. Awesome! However, before posting your first question to the Boost mailing list, please, do read the official GSoC student guides [0]. All of it. [0] https://google.github.io/gsocguides/student/ I also recommend to read through other resources dedicated for students, especially this one from Google [1], one from a former student [2] as well as advice from Boost GSoC former student Louis Dionne [3]. [1] https://opensource.googleblog.com/2011/03/dos-and-donts-of-google-summer-of… [2] https://medium.com/@akshikawijesundara/google-summer-of-code-dos-and-do-not… [3] https://github.com/boostorg/wiki/wiki/Google-Summer-of-Code%3A-Advice-From-… Once you get through the general GSoC materials, it's a good idea to start browsing Boost resources, from intro [3] through netiquette [4] to wiki [5]. On [3] and [5] you will find links to past and current project ideas for Boost libraries. Browse it, read it, and learn what kind of projects Boost community develops during GSoC. Start thinking about what interests you, which Boost library, which project, what you'd like to develop as GSoC student. [4] https://www.boost.org/community/gsoc.html [5] https://www.boost.org/community/policy.html [6] https://github.com/boostorg/wiki/wiki Meanwhile, it's a good idea to "Make First Contact" [0]. Subscribe to the boost (developers) and boost-user or library-specific mailing list at https://lists.boost.org join Boost channels on Slack at https://cppalliance.org/slack/ and start discussing your participation, project ideas, etc. Although the student guides [0] use the phrase about "communicating directly with potential mentors", it does NOT mean exchanging private e-mails with mentors asking "Are you interested to mentor me?". GSoC does not work this way. In my opinion, the word "directly" means to interact directly with the community where, obviously, potential mentors are members too. The Boost organization and mentors will have chance to select students and projects they wish to mentor during the selection process - a secret, you can learn about it from GSoC guides for mentors [8]. Yes, the selection is a competitive process. [8] https://google.github.io/gsocguides/mentor/selecting-a-student Next, start discussing project of your interest, start asking questions, investigate ways to contribute to Boost, start working on competency tests Mind you, competency test is Boost way to verify minimum necessary skills. I personally think Boost should also ask for a bug fix [2] explains: "Some organizations make it a must for you to fix a bug in their code base before submitting a proposal but some do not. Your chances are always high if you can fix a bug in the code." Submitting a pull request with a small feature is also a good idea, something to discuss with mentors/maintainers of library of your interest Pull requests will allow you to gain hands-on experience with workflow of peer reviews, continuous communication, addressing problems, testing your solution, using the infrastructure, being exposed to stress of 'annoying' requests from maintainers to fix this, tweak that... :-) For example, it worked well for Boost.GIL (you can PRs at https://github.com/boostorg/gil) "you have to go early even if you go to hell" [2] GSoC IS hard work! Make sure to start early, to take a proactive stance, to do your homework before you start asking questions, to expect no babysitting. Imagine the GSoC runs back in times when there is no StackOverflow, no web archives, no web search,... There really is no excuse for not searching the web first nowadays. Even compilers can do that! https://arxiv.org/abs/1906.11456 "To grow in life, be willing to suffer" ~David Goggins Have a great time during GSoC and good luck!

[static_string] Boost.StaticString (fka FixedString) accepted into Boost
by Joaquin M López Muñoz 24 Feb '20

24 Feb '20

Hello, Boost.StaticString (formerly known as FixedString) was accepted into Boost subject to the resolution of a number of issues I listed as priority 1: https://lists.boost.org/Archives/boost/2019/12/247820.php I've checked with the author that these issues have been already solved, so Boost.StaticString is good to go as an official Boost library (hopefully in time for shipping with 1.73). Thanks to Krystian and Vinnie for their work. Welcome Krystian to the dubious club of Boost authors :-) After the hard work needed to get the lib in, now comes the not less hard part of keeping it updated and generally healthy. Best regards, Joaquín M López Muñoz Review manager for candidate Boost.FixedString (now Boost.StaticString)

[gsoc2020][Boost.GIL] Advice needed regarding competency.
by sarthak 23 Feb '20

23 Feb '20

Hi everyone, I am Sarthak, a second year undergraduate engineering student. I wish to contribute to boost open source development during gsoc2020, specifically to Boost.GIL. But, I am not sure whether I am competent enough to contribute meaningfully to the organization (see the last point for precise question), I am hoping that someone here can give me advice regarding the same :) First, my reasons to contribute to boost - - I am reasonably proficient in programming (C++ included). I know I will be able to demonstrate it through programming competency test and all. In my day to day programming I normally do not use meta programming techniques which are prevalent in boost, this has made me more excited to work on boost because I will get to use these new fancy constructs :D - I just want to be part of open source community for once, sincerely. I have been using FOSS since forever and as a developer I have been longing to pay back, this is a good chance for me to do the same. - Why boost over any other organization? Largely because C++. I like the multi-resolution philosophy of C++ that you can get as close to machine as possible, or you can do high level manipulations through libraries and generics. More on that in proposal ;) - Why GIL (Project 1)? I want to learn image processing. Now this is where it gets tricky, the thing is that I am passionate about doing image processing, but I am not well versed with its theory. I have done a course on Signals and Systems in my university but that is pretty much it. This means that at the least I would need to learn image processing algorithms as we go on. Not that I hate it (on the contrary in fact) but that I am not really sure if it is possible at all for someone like me to contribute meaningfully during the few months of GSoC. I would love to hear from a mentor's experience of previous students on this. Honestly I would like to be rejected now if at all than after submitting my proposal with false hopes, or worse moving on with GSoC with such false hopes. I can also contribute to boost multiprecision in which I am substantially more experienced, but my first interest is in GIL and therefore if possible I would like to take the project in GIL. Any advice is appreciated. Thanks for reading. -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Dev-f2600599.html

Fwd: Open Source Hackathon Mentor Invitation
by David Bellot 23 Feb '20

23 Feb '20

A word from our friends doing C++ at Hackillinois Outreach... ---------- Forwarded message --------- From: Advai Podduturi <advai.podduturi(a)hackillinois.org> Date: Wed, Feb 19, 2020 at 7:56 AM Subject: Open Source Hackathon Mentor Invitation To: <david.bellot(a)gmail.com> Hello, My name is Advai Podduturi and I’m reaching out on behalf of the HackIllinois Outreach team. HackIllinois is a 36-hour collegiate Open Source hackathon that takes place annually at the University of Illinois Urbana-Champaign. This year, it will be from February 28th - March 1st, 2020. Our mission is to introduce college students to Open Source, while giving back to the community. We strive to create a collaborative environment in which our attendees can learn from and work with developers to make their own contributions. In past years, we’ve had developers from prominent projects such as npm, Rust, and Apache come to mentor students from our pool of 900+ attendees.

Our logo on the GSoC page[1] looks a little pixelated and small fonts are not readable can we replace it? I have attached a boost logo file in the mail and a transparent logo can also be found here[2] [1]: https://summerofcode.withgoogle.com/organizations/6011808097239040/ [2]: https://de.wikipedia.org/wiki/Boost_(C%2B%2B-Bibliothek)#/media/File:Boost.… Thank you, Pranam Lashkari

Hello everyone. My name is Ahmed ElShreif and I'm a newcomer to the Boost community. I am willing to apply this year in GSoC with boost. I was accepted in LibreOffice in GSoC'19. I read the Projects and it's really interesting for me. But I have some questions: why this projects exist also in 2019 potential projects? Can I get help in finding some easy issues to solve now to get familiar with the library more and become ready more for the project? Thanks Ahmed ElShreif -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Dev-f2600599.html
