kandi X-RAY | GSL Summary

GSL is a C++ library typically used in Utilities, Command Line Interface, Angular, Nodejs applications. GSL has no bugs, it has no vulnerabilities and it has medium support. However GSL has a Non-SPDX License. You can download it from GitHub.

The Guidelines Support Library (GSL) contains functions and types that are suggested for use by the C++ Core Guidelines maintained by the Standard C++ Foundation. This repo contains Microsoft's implementation of GSL. The entire implementation is provided inline in the headers under the gsl directory. The implementation generally assumes a platform that implements C++14 support. While some types have been broken out into their own headers (e.g. gsl/span), it is simplest to just include gsl/gsl and gain access to the entire library. NOTE: We encourage contributions that improve or refine any of the types in this library as well as ports to other platforms. Please see CONTRIBUTING.md for more information about contributing.

Trying to install package brms in R

Asked 2022-Apr-16 at 19:16

I'm trying to install the package brms in R so that I can rename the parameters returned from the function stan (from the rstan package). When I try install.package("brms", dependencies=TRUE), I get the (partial) output pasted at the end of this post (it's too long to paste the whole thing). At the end of the output, you can see that I get a series of "dependency errors", which makes sense because the very first error is not a dependency error, but rather a compilation error that says:

The point of suggestion by code analysis is to check narrowing conversion

int{value} is narrowing conversion that can be checked in compile-time, if value is constant. int{mapHistory.size()} should not compile.

gsl check is runtime, so it will actually check the value range in your case. To make it compiling, obtain gsl library, and make it available to the compiler.

Overloading == and !== when object is a pointer

I am new to writing operators (in this case == and !=). I have done a bit of research and so far came up with:

ANSWER

Answered 2022-Feb-16 at 16:29

Function can be used both by the object when it is / is not a pointer.

Actually, no it can't. In a statement/expression like object->Function(value) the -> (member access) and () (function call) operators have the same precedence and left-to-right associativity. So, the -> is applied first and that automatically dereferences the pointer. So, the effect is the same as (*object).Function(value) – and Function is still being called on an object, rather than on a pointer.

So why not with an operator?

The syntax for calling an operator function is (or can be) rather different: because it is defined as an operator, you can call it using the operator token (between the two operands) rather than by using an explicit function call. But then, you have to pass objects, as that's what the operands are defined to be.

However, should you really want to, you can still call an operator override using explicit function-call syntax; and, in that case, you can use the -> on a pointer; like this (where operator== is effectively the 'name' of the function):

I successfully cross-compiled the GNU Scientific Library for my STM32F303 with an Arm Cortex M4, as I've described here:

As in the comments described, I've used indeed the wrong linker script during cross-compiling (the default linker script). It worked after specifying the linker-script (I had to use the linker-script for the specific MCU).

How to crosscompile GSL for Arm Cortex M4?

Asked 2022-Jan-31 at 07:49

I am using a STM32 MCU with arm cortex m4 and want to use the gsl-2.7.1. However, I already tried for example the command ./configure --prefix=/home/user_name/gsl_arm --target=arm-none-eabi and every other suggestion that I could find on the internet and toolchain-tutorials, but in the best case I got during linking with the build library an error like "could not recognize the symbols". In the worst case, the suggested options for autoconfig were not recognized (for example, to specify the cpu). Does anyone have an idea how I have to crosscompile it?

You named your thick wrapper library gsl. The library you're wrapping is also named gsl. Internally, this will cause the linker to get -lgsl two times, and both will be resolved to your thick wrapper. This is why it's missing the symbols from the original library.

Change the Library_Name of your thick wrapper to resolve this.

QUESTION

How do I replace this raw loop with an STL algorithm or iterators? (avoiding unchecked subscript operator)

Asked 2022-Jan-04 at 16:36

I'm implementing a generic clone of the Snake game in C++ as an exercise in following the C++ Recommended Guidelines. I'm currently working on the Snake's update() method, which is tiggering a Guideline-violation for using the unchecked subscript operator in a for loop:

Prefer to use gsl::at() instead of unchecked subscript operator (bounds.4).

I want to avoid the redundant range change check of gsl::at() / container::at(), and don't want to suppress the warning either. With that in mind, how can I replace this raw loop with something more Guideline-friendly? (eg. an STL algorithm, iterators, what have you)

ANSWER

Answered 2022-Jan-04 at 16:36

You can std::rotate the snake so that the old tail is the front element, and then overwrite that with the new segment.
