Is boost supported on z/os
by Naveen Sharma 28 Oct '18

28 Oct '18

Hello Does boost supported on z/os or may be subset of library. We are planning to replace our current library with boost. One of the platform we support is z/os and so I am researching if boost can be compiled and usable on the platform. I did searched on the internet but did not get much information. Before I dive into it, I thought to ask. Thanks Naveen

However, you may consider making parts of the library available to C++11 users, because there are plenty of those out there.

[statechart] visibility change broke things
by James E. King III 27 Oct '18

27 Oct '18

Boost.StateChart wasn't building on a regular basis. It looks like the visibility changes broke it. I opened an issue for it. I also changed Travis CI to build it monthly.

Fwd: Syntax highlighting for Boost.Jam language in Visual Studio Code
by Mateusz Loskot 27 Oct '18

27 Oct '18

I've announced this on boost-build but I think folks here may find it useful as well. Mat ---------- Forwarded message --------- From: Mateusz Loskot <mateusz(a)loskot.net> Date: Fri, 26 Oct 2018, 23:18 Subject: Syntax highlighting for Boost.Jam language in Visual Studio Code To: <boost-build(a)lists.boost.org> Hi, (A pet project warning!) I've published an extension for VSCode with a brave attempt to color-hightlight syntax of Jam language: https://github.com/mloskot/vscode-boost-jam This is based on a very basic TextMate language grammar definitions, often naive, and, by no means, it is complete or bug-free coverage of the Jam. Even so, I think it quite helps to de-annoy or even enjoy process of writing Jam scrips :-) I'm no expert of writing TextMate language grammars - this is my first ever attempt - so chances are I may be incapable of fixing bugs or improving it with advanced features. Especially, that "the process of writing a TextMate language grammar remains poorly documented" - http://www.apeth.com/nonblog/stories/textmatebundle.html Best regards, -- Mateusz Loskot, http://mateusz.loskot.net

[parameter_python] Merge to master
by Edward Diener 26 Oct '18

I would like to merge parameter_python to 'master' from 'develop'. Does anybody see anything wrong with this ? This fixes using Python 3+ with parameter as well as Python 2+, among other things.

Library devs only: Boost v2.x distro design questions
by Niall Douglas 26 Oct '18

26 Oct '18

Splitting this off from the other thread, can I get feedback from Boost library maintainers ONLY. Not users, not non-maintainers. Q0: Are you willing to do the work to adapt your library for any Boost v2.x distro if it were to happen? Q1: Would you prefer a new, separate Boost v2.x distro in parallel to the v1.x distro, or to keep everything within one v1.x distro? Q2: Would you be intending to keep your library inside Boost v1.x, move it exclusively to Boost v2.x, or have it exist in both Boost v1.x and v2.x but with different defaults configured? Also, would the version in v1.x be hard forked from any v2.x edition i.e. the v1.x edition would get orphaned? Q3: What C++ standard should Boost v2.x's master build system be defaulted to? C++ 11, 14, 17 or 20? Q4: Should Boost v2.x use a boost2 namespace, or namespace boost { inline namespace v2 { }}? (This affects whether Boost v2 and v1 editions of your library can be used within the same translation unit) Q5: What master buildsystem should Boost v2.x use? Boost.Build, cmake, Build2, something else? Q6: Should Boost v2.x's libraries auto integrate individually into some package manager? If so, which ones do you intend to support? Q7: Should Boost v2.x have official release versions done by release managers, or should it be a rolling release of "whatever last passed the CI @ 100%"? Note that you can have this, and have official release versions of "especially known good" editions too. Q8: Should Boost v2.x use a local HTML server to serve documentation, and the static HTML docs be dispensed with as a requirement? Q9: What are your feelings towards the use of Python to script infrastructure and tooling in any Boost v2.x? For example, Python to run a local HTML server to serve documentation locally, or Python to build a release etc Q10: What parts of core Boost are you utterly dependent upon, and would absolutely need ported to any Boost v2.x as no STL alternatives exist? I could go on, but let's stop there for now. Niall

[histogram] Objections against switch to C++14?
by Hans Dembinski 26 Oct '18

26 Oct '18

Dear reviewers of boost.histogram, thank you again for your reviews. I am currently working on the issues raised during the review and some of the requested features would be easier to implement when the library standard is raised from C++11 to C++14. This only affects the implementation side, not the user side. It would make my life easier and the implementation code more readable, because I can emulate `if constexpr` using in-place generic lambdas instead of out-of-place functors in the detail namespace. To make the library more user-friendly, I have to do more and more of these emulated `if constexpr`. Do you object against raising the requirement from C++11 to C++14 for the implementation of boost.histogram? Best regards, Hans
