重要更新：

问题的答案中描述了一个更改进的脚本，它只需要一个有效的 python 环境。

原始答案

请参阅我在Boost邮件列表中对您的问题的回答。

以下 bash 代码将为 51 到 100 个条目生成 MPL 容器。如果您不关心其他 MPL 容器类型，只想生成 MPL 列表，请相应地调整CONTAINERS的值。

python preprocess.py        all ${SOURCE}
# Leave source-directory of Boost.MPL.
popd  >/dev/null 2>&1

对于条目超过 100 个的更大容器，请调整 for 循环中的范围。

我希望这有所帮助。

更新：

我意识到我的脚本原始版本只生成了 MPL 容器标头的编号版本。但是，它没有更新未编号的版本。

我通过在脚本末尾附近添加python preprocess.py all ${SOURCE}来修复它。但是，如果生成过程中相应的宏设置（例如，BOOST_MPL_LIMIT_VECTOR_SIZE 的值较高）与原始值不同，则这只会生成未编号的 MPL 容器标头的修改版本。

这些修改可以在 ${SOURCE}/libs/mpl/preprocessed/include 的每个子目录中的文件user.hpp中进行。

例如，通过添加

#define BOOST_MPL_LIMIT_VECTOR_SIZE 30

为了${SOURCE}/libs/mpl/preprocessed/include/gcc/user.hpp boost::mpl::vector（包含在boost/mpl/vector.hpp）现在能够容纳30个元素，而不是默认的20个。

注意：

但是，仅针对生成调整 BOOST_MPL_LIMIT_VECTOR_SIZE 等值并将其在 ${SOURCE}/boost/mpl/limits/vector.hpp 中定义的值保持不变可能不是一个好主意。
可能，这甚至不会编译，因为找不到要boost::mpl::vectorN的基础boost::mpl::vector21（因为没有自动包含）。最好的解决方案可能是调整${SOURCE}/boost/mpl/limits/vector.hpp中的值。如果给出了第二个（可选）参数，上面的 bash-script 可以自动执行此操作。

最终更新

从 Boost 1.59.0 开始，下面解释的脚本现在包含在每个 Boost 版本中。

它们位于 int /libs/mpl/preprocessing/。

该目录中的自述文件.txt应说明如何使用它。（或者继续阅读。

原答案

因为我意识到不是每个人都有一个工作 bash shell（是的，我的意思是你们 Windows-guys ;-）），但每个人都需要一个有效的 python 环境，我将我上面提到的辅助程序 bash-script 转换为 python：

运行它

python boost_mpl_preprocess.py --help

提供了一些使用信息。

但您也可以使用单个命令行参数运行它，该参数确定 Boost 源目录的路径（例如 python boost_mpl_preprocess.py ./boost-source ） 并使用默认行为。

这导致为所有四种Boost.MPL容器类型（vector，list，set和map）创建预处理的标头，并带有编号和可变形式。

注意：

作为以可变参数形式预处理 Boost.MPL 容器时的副作用，其关联的限制宏BOOST_MPL_LIMIT_container_SIZE的值也会被修改。它获取调用boost_mpl_preprocess.py时确定的元素数。

例如，以下调用仅预处理 Boost.MPL vector的可变参数形式，并将 ./boost-source/boost/mpl/limits/vector.hpp 中的宏BOOST_MPL_LIMIT_VECTOR_SIZE设置为 70 。

$ python boost_mpl_preprocess.py --no-list --no-set --no-map 
    --sequence-type=variadic --num-elements=70 ./boost-source

更新

由于 Boost 1.56 预处理 Boost.MPL 容器即使使用上述脚本也不再工作，由于标头注释的变化，原始 python 脚本依赖于。

以下脚本可用于解决此问题。它只是将缺少的信息添加到标题注释中。

if __name__ == '__main__':
    main()

像这样运行它：

$ python fix-boost_mpl_preprocess.py ./boost-source
