the changes look clean, i'll squash merge this

altho i consider this tool obsolete, when new tool is ready:
smarty-gettext/tsmarty2c#1

Thanks! Do you plan a new official release that includes the changes? Would be much appreciated.

Looking forward to the initial release of the rewritten tool.
In regards to domain support, it would be nice to add an option to automatically output strings into separate files per domain (.pot) during parsing. With the current code, this would have required major refactoring. So we went with the simple filtering approach for now. Maybe you can plan for this in the new tool architecture.

file as ticket in the new project what's the goal how you see the interface. or wait when current functionality is there and submit PR.

and yes. i'll do release soonish.
