Hi Tom,
Overall this looks great. I'm not too worried about internationalization.
I think in this case for example:
_("The \"%s\" display intensity is: %s\n"), name, value
If "name" corresponds to a field name or sub-command name (like "filename"),
it's probably better to leave it in english. If it refers to the concept
of a filename, then we would want to translate it.
In the latter case, I guess we could do it in two steps, and also pass the value
through gettext:
std::string tmpl = string_printf ("The %s display intensity is: %%s\n", name);
printf (_(tmpl.c_str ()), _(value));
So tmpl would contain "The filename display intensity is: %s\n", which could be
looked up by gettext to something that has the proper translation for "filename".
Then, the color name would be translated too.
Or maybe I don't understand how gettext works.
I'm just not sure about choosing styles using the field name. For a filename, you could
have a bunch of different field names, file filename, original_filename, absolute_filename,
etc. So it can quickly become a bit crowded here.
Could we pass an additional enum parameter to do_field_string to indicate the type of
element this field represents? If this parameter has a default value of "NOTHING",
then we can add then incrementally. Or it can even be an hybrid approach, where we
try to match field names, which works 95% of the time, and then have this enum parameter
to override the auto-detection if needed.
