kandi X-RAY | paqu Summary

paqu is a PHP library typically used in Automation, Crawler applications. paqu has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

PaQu is a parallel querying facility that works together with the MySQL Spider engine. It is built on a similar project using Gearman (shard-query: and has been forked from there at an early stage. It has been heavily extended and altered to suite our needs. The general idea of PaQu is to take a query, analyse it and automatically shard/parallelise it to be run on the different Spider nodes. This is achieved in a map/reduce kind of fashions. Results are then gathered on the head node and further reduced if aggregation is needed. To have an idea how to use PaQu, have a look at paraQuery.php until I find the time to write a detailed introduction on how to use PaQu. Or use the Daiquiri web framework (escience.aip.de/daiquiri) to interface to your Spider database from the web using PaQu. A command line tool is also provided to run queries against a predefined server setting. The command line tool is in paqu.php.

Cannot print string with std::end

QUESTION

Cannot print string with std::end

Asked 2017-Nov-09 at 22:02

I am having trouble with printing a string in C++.

I know there are lots of topics about this matter on SO, but most say to include , or namespace std. But I did all of that but still encounter the issue. Here is my code and the error.

std::end() is a function for getting an iterator to the end of a container.

You meant to use the std::endl stream manipulator instead.

Note: avoid using namespace std; in your actual code, either take advantage of using directives to bring in only what you need, or favor qualifying names with their namespaces, like I have here.

Install paqu

You can download it from GitHub.
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
