At the moment, I think that proposed solution would result in infinite recursion. We'd have to move the part of set_font()
that sets self.current_font
into an internal method _set_font()
to avoid this, and only use that one from the other property setters.
I agree that in the user facing API, we should try to treat "bold", "italic", and "underline" as similarly as possible. When storing them internally though, collecting them into a single "emphasis" string seems to make their use a bit cumbersome. Alternatively we could just as well store three booleans seperately, and only combine them into a string when the user requests one. It will take a bit of code analysis to figure out which strategy will result in the simpler code overall. Currently the font selection key is created by appendeing a "[b]?[i]?" string to the family, though. Is there a more straightforward way to do that?

Yes, you are right, we would have to take care of that.

Could you please develop a bit why?
This may be subjective, I find this actually a lot more elegant & handy than having 3 attributes ๐
I see the following "factual" benefits of having a single attribute (._emphasis
) instead of 4 distinct ones:

source code.

Problem As demonstrated in https://github.com/py-pdf/fpdf2/issues/1220#issuecomment-2221497527, currently setting
pdf.font_style = "B"
does not properly apply a bold emphasis to the following text:Describe the solution you'd like
As part of this change, I suggest to replace the
.underline
&.font_style
attributes ofFPDF
by getters & setters modifying an underlying._emphasis
property.RFC: Whad fo you think of this proposal?
