I think this is sort of what I was meaning by an external option. Well may be I was thinking it could potentially go further or it could be as you describe.
May be it could be C may be it could be another language, if it is not mixed in then this does not matter too much, and whoever writes it could use which they feel is most appropriate. "Appropriate" including ensuring that it is usable by those who need access to the functionality, so realistically it probably would be a choice between C, C++ or other language which can be used from C and has no large dependencies.
May be it could be called near the end of the liblouis translate function, then consumers of liblouis need not deal with additional function calls and that complexity.
If it is C or C++ may be it could be statically linked to liblouis and then no additional dependencies are to be handled.
I think I am getting more convinced that it might be the quickest option to implement.
The only bit I cannot quite work out is whether the Braille string and typeforms would be enough to apply the emphasis indicators or whether one needs to have access to the original text.

John. Do you think the approach I mentioned would work? That is to basically strip out code that does emphasis now and create a new post-translation procedure that takes care of it. We could keep it in C but try to encapsulate it at least to the point that the procedure is in one location and not intermingled with other translation code. It would require a separate pass over the braille output but shouldn't introduce much of a performance hit. -----Original Message----- From: liblouis-liblouisxml-bounce@xxxxxxxxxxxxx [mailto:liblouis-liblouisxml-bounce@xxxxxxxxxxxxx] On Behalf Of John J.

They might be used with the liblouis exactdots opcode, but I think the best approach and the least frustratingu would be to simply redesign the emphasis code in liblouis from scratch.

I just never saw an email about how the macro bit could sollve the emphasis issueswhich weneed for italic, bold, underline in UEB. We have a new volunteer starting Friday so I hope will soon be able to reverse engineer the macro code and hopefully give us a solution.
