分享一个代码合并工具

跨平台命令行工具(Amalgamate)，用于生成C或C ++源的合并成一个文件。

  合并是仅使用几个文件(低至一个或两个)来分发库源代码的另一种方法。该工具通过内联包含的文件以创建一个或多个大型源文件或头文件来产生合并。

  对于成熟的库(即不经常更改)，合并后的发行格式通常更易于集成和更新。合并将作为附加源文件添加到现有项目，而无需由构建工具单独构建。以下是一些已合并的源代码库示例：

  NAME

   amalgamate - produce an amalgamation of C/C++ source files.

  SYNOPSIS

   amalgamate [-s]
     [-w {wildcards}]
     [-f {file|macro}]...
     [-p {file|macro}]...
     [-d {name}={file}]...
     [-i {dir}]...
     {inputFile} {outputFile}

  DESCRIPTION

   Produces an amalgamation of {inputFile} by replacing #include statements with
   the contents of the file they refer to. This replacement will only occur if
   the file was located in the same directory, or one of the additional include
   paths added with the -i option.

   Files included in angle brackets (system includes) are only inlined if the
   -s option is specified.

   If an #include line contains a macro instead of a string literal, the list
   of definitions provided through the -d option is consulted to convert the
   macro into a string.

   A file will only be inlined once, with subsequent #include lines for the same
   file silently ignored, unless the -f option is specified for the file.

  OPTIONS

    -s                Process #include lines containing angle brackets (i.e.
                      system includes). Normally these are not inlined.

    -w {wildcards}    Specify a comma separated list of file name patterns to
                      match when deciding to inline (assuming the file can be
                      located). The default setting is "*.cpp;*.c;*.h;*.mm;*.m".

    -f {file|macro}   Force reinclusion of the specified file or macro on
                      all appearances in #include lines.

    -p {file|macro}   Prevent reinclusion of the specified file or macro on
                      subsequent appearances in #include lines.

    -d {name}={file}  Use {file} for macro {name} if it appears in an #include
                      line.

    -i {dir}          Additionally look in the specified directory for files when
                      processing #include lines.

    -v                Verbose output mode

• 使用示例
  合并main.cpp内所有的#include "文件名字"的内容到out.cpp中。(注意: 不合并#include <文件名字>)

amalgamate main.cpp out.cpp
