Question

美好的一天。

我需要在我的Qt代码中访问特定的QBS变量。

一个例子是应用程序的名称，组织或风味，所有在我的应用程序qbs文件中指定的变量。

>>> reordered = df.sample(n=df.shape[0])
>>> lim = reordered[reordered.Money.cumsum() < 80000000]

在查看QBS的Qt文档时，我找不到在Qt代码中使用QBS变量的任何参考。

This是使用QBS变量的唯一链接，但仅在QBS文件内

我想这样做：

import qbs

Project {

    // These variables should be available in C++ code.
    name: "my_app_name"
    organization: "Organisation_Name"
    flavour:"AppFlavour"
    minimumQbsVersion: "1.7.1"

    CppApplication {
        files: [
        ]
        Depends { name: "Qt"; submodules: ['core', 'network'] }

        cpp.cxxLanguageVersion: "c++11"

        cpp.defines: [
            "QT_DEPRECATED_WARNINGS",
        ]

        consoleApplication: true

        Group {
            name: "source"
            files: [
                "qconfigurationmanager.cpp",
            ]
        }

        Group {
            name: "header"
            files: [
                "qconfigurationmanager.h",
            ]
        }

        Group {     // Properties for the produced executable
            fileTagsFilter: "application"
            qbs.install: true
        }
    }
}

我该怎么做？

一个可能的选择是使用DEFINES并通过宏获取数据：

import qbs

Project {
    minimumQbsVersion: "1.7.1"

    property string name: "my_app_name"
    property string organization: "Organisation_Name"
    property string flavour:"AppFlavour"

    CppApplication {
        Depends { name: "Qt"; submodules: ['core', 'network']}
        cpp.cxxLanguageVersion: "c++11"
        consoleApplication: true

        cpp.defines: [
            "QT_DEPRECATED_WARNINGS",
            "name=" + project.name,
            "organization=" +  project.organization,
            "flavour=" + project.flavour
        ]
...

#define QUOTE_(x) #x
#define QUOTE(x) QUOTE_(x)

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QString appname = QUOTE(name);
    QString organization = QUOTE(organization);
    QString appflavour = QUOTE(flavour);

    qDebug()<< appname << organization << appflavour;

...

输出：

"my_app_name" "Organisation_Name" "AppFlavour"
