Could you explain how changing

into

(as far as I can tell, this is t= he only modification) is supposed to achieve the desired effect?

Ah, well I don't think that you inclu= ded this in your original message, so I thought that was the problem :).

return {{Meta =3D get_default_code_class},
=C2=A0= =C2=A0 =C2=A0 =C2=A0 {Code =3D add_default_code_class},
=C2=A0 =C2=A0 = =C2=A0 =C2=A0 {CodeBlock =3D add_default_code_class}}

You are correct: the only difference is that you have Code. You cou= ld combine Code and CodeBlock into a single pass, as in:

return {{Meta=3Dget_default_code_class},
=C2=A0 =C2=A0 =C2=A0 =C2= =A0 {Code=3Dadd_default_code_class, CodeBlock=3Dadd_default_code_class}}

But it _does_ work for me! Maybe add some debug = output? Here I'm using my own inspect-like function but the standard in= spect would probably be similar.

Pandoc version? I= 'm using 2.14.1.

I think you need a two-pass filter, one to pick up the metadata a= nd the other to use it (this is because Meta is called nearly last).
This works (I've re-ordered your functions and declared a = local variable, but this probably wasn't necessary).

% = cat defau= lt-code-class.lua=C2=A0

local default_code_classes =3D= {}


function get_default_code_clas= s(meta)

=C2=A0 if meta[&#= 39;default-code-class'] then

=C2=A0 =C2=A0 def= ault_code_classes =3D {pandoc.utils.stringify(meta['default-code-class&= #39;])}

=C2=A0 end=

end


function add_default_code_clas= s(el)

=C2=A0 if #(el.cl= asses) =3D=3D 0 then

=C2=A0 =C2=A0 el.= classes =3D default_code_classes

=C2=A0 =C2=A0 ret= urn el

=C2=A0 end=

end


return {{Meta=3Dget_default_co= de_class}, {CodeBlock=3Dadd_default_code_class}}
