[cmake-developers] daemon-mode: Project structure

[Tobias Hunger]

Hello everybody,

I made some progress with extracting project structure from cmake via the
daemon-mode. I am rather happy with the information and would love to get some
feedback from other interested parties.

Here is the format that is currently reported (with comments;-):

[== CMake MetaMagic ==[
{
  # Reply header:
  "cookie":"",
  "type":"reply"
  "inReplyTo":"project",
  
  # Data:
  "projects":
  [
    {
      "configurations":
      [
        {
          "name":"",
          "targets":
          [
            {
              "fullName":"test",
              "name":"test",
              "type":"GLOBAL_TARGET"
            },
            # <snip>
            {
              "buildDirectory":"/tmp/cmake-build-test/Source/CursesDialog/form",
              "fullName":"libcmForm.a",
              "linkerLanguage":"C",
              "name":"cmForm",
              # "sysroot": "/some/path", if set...
              "sourceGroups": # Just groups files with similar settings
                              # together to save space
              [
                {
                  "compileFlags":"  -std=gnu11",
                  "defines":
                  [
                    "CURL_STATICLIB",
                    # <snip>
                    "LIBARCHIVE_STATIC"
                  ],
                  "includePath":
                  [
                    "/tmp/cmake-build-test/Utilities",
                    # <snip>
                    "/home/code/src/cmake/Source/CursesDialog/form"
                  ],
                  "lanugage":"C",
                  "sources":
                  [
                    "fld_arg.c",
                    # <snip>
                    "fty_regex.c"
                  ]
                }
              ],
              "type":"STATIC_LIBRARY"
            },
            # <snip>
            {
              "fullName":"install",
              "name":"install",
              "type":"GLOBAL_TARGET"
            }
          ] # end of tragets list
        } # end of one configuration object
      ], # end of configurations list
      "currentBuildDirectory":"/tmp/cmake-build-test/Source/CursesDialog/form",
      "currentSourceDirectory":"/home/code/src/cmake/Source/CursesDialog/form",
      "name":"CMAKE_FORM"
    }, # end of one project object
    # <snip>
  ] # end of project list
}
]== CMake MetaMagic ==]

Is this the information you need for IDE integration?

Do you cmake developers feel comfortable to expose this information?

The total of the project data from the cmake project is ~102KiB of raw JSON
data.

What is not listed is the build system file list and the CMakeCache. I want to
keep these two separate: I can think of some use cases where that information is
not at all necessary:-)

Best Regards,
Tobias
