Added support for the Meson Build System

[eidheim]

Should be 100%, but some additional testing needed. Let me know if there are any issues or not.

[zalox]

I'll have a look, please give me some time to learn meson.

[eidheim]

Sure, and thank you:)

std::copy_if(parameters.begin(),paramerters.end(),parameter_values.end(),[](){}));

[eidheim]

The function gets more complicated if copy_if is to be used:

std::vector<std::string> CompileCommands::Command::paramter_values(const std::string &parameter_name) const {
  std::vector<std::string> parameter_values(parameters);

  bool found_argument=false;
  auto it=std::copy_if(parameters.begin(), parameters.end(), parameter_values.begin(),
               [&parameter_name, &found_argument](const std::string &parameter){
    if(found_argument) {
      found_argument=false;
      return true;
    }
    else if(parameter==parameter_name) {
      found_argument=true;
      return false;
    }
    return false;
  });
  parameter_values.resize(std::distance(parameter_values.begin(), it));

  return parameter_values;
}

[zalox]

std::copy_if(parameters.begin(),paramerters.end(),parameter_values.end(),[&parameter_name](const std::string &param){
  return parameter_name == param;
}));

[eidheim]

This is not the same. The idea is to return for instance some_file after -o some_file when the parameter_name is -o.

[zalox]

Ohh, sorry I missed the else if, but at least this made me notice the miss spelt paramter_name.

[eidheim]

I fixed the misspelling yesterday:)

[zalox]

Did you push the spellfix? It still says paramter for me.

[zalox]

Correct me if I'm wrong, but I think read_json can cause problems. I think there is a error_code version.

[eidheim]

This should be safe, since the exceptions are caught.

[zalox]

std::npos?

[eidheim]

Indeed, will fix

[zalox]

Suggestion:

if(project_path.empty() || default_build_path.empty())
    return false;
if(!boost::filesystem::exists(project_path/"meson.build"))
   return false;

[eidheim]

Will clean up this as well.

[zalox]

This calls for abstraction, but I agree to wait if we are introducing more build systems.

[eidheim]

@zalox Are you happy with the changes? Can we merge this PR?

[eidheim]

@zalox the spelling errors should be fixed now. Thought that I had fixed them, but apparently not all.

[zalox]

Looks good, sorry about my late responses, been flying all over Europe!
