How to get the flags (key, value) pairs into a json object?

Hi dev team,

How do we get the (key, value) mapping from FLAGS if we want to save them?

There is some lightweight serialization / deserialization support:

To save, use FLAGS.append_flags_into_file() or FLAGS.flags_into_string() for serialization of all flags
To restore, specify --flagfile=<somefile> on the command line pointing to a file containing the above content, or call FLAGS.read_flags_from_files(['--flagfile=<somefile>'])

If you really need json, you'll need to do it manually. Take a look at

Lines 1183 to 1190 in 06edd9c

    
           module_flags = sorted(self.flags_by_module_dict().items()) 
        
           s = '' 
        
           for unused_module_name, flags in module_flags: 
        
             flags = sorted(flags, key=lambda f: f.name) 
        
             for flag in flags: 
        
               if flag.value is not None: 
        
                 s += flag.serialize() + '\n' 
        
           return s

how to get all flags and their serialized value.

Hope this helps.
