[lldb-dev] Help on the way to retrieve header file list

[Yin Ma]

Hi Greg,

Thank you for the quick answer. I will go ahead to 
implement a pass to remove the redundancy in the list.

Thanks,

Yin

No. But you can take advantage of the fact that the basenames and directories returned from the SBFileSpec are uniqued C strings:


    const char *
    SBFileSpec::GetFilename() const;

    const char *
    SBFileSpec::GetDirectory() const;

So you might be able to use that to your advantage to help you unique these files into a std::set:

typedef std::set<std::pair<const char *, const char *>> PathSet;

PathSet unique_paths;

Then you can run through all files and do:

for (SBFileSpec cu_file : ...)
{
    unique_paths.insert(std::make_pair(cu_file.GetDirectory(), cu_file.GetFilename()));

    for (SBFileSpec support_file : ...)
	unique_paths.insert(std::make_pair(support_file.GetDirectory(), support_file.GetFilename()));

}

This should solve your problem for you?

Greg
