Greetings all.
I am currently trying to typeset my thesis with the very nice latex
generation capabilities that Isabelle provides. I have a few questions.
Firstly, when printing proofs, Isabelle does a very nice job of
typesetting the keywords and indentations of the proof scripts, but
the actual object logic terms keep their x-symbol syntax and not the
nice latex sugar that I have defined for them. Is there any flag to
set which would translate them in the same manner as is done when
using the @{term...} antiquotation?
Secondly, I have some very large induction rules which I would like to
present and every case of these rules have all of their parameters
meta-quantified. Is there a mode which removes the actual meta-
quantification? It takes up a lot of space, and the absence of the
quantifiers can be explained in figure captions in stead. What I would
like to do is an equivalent of @{thm_style [mode=Rule] premxx
myInductionRule}, but without the preceeding /\x y z ... . I'm
guessing either a new style or mode is required.
I have been reading through the reference manual, but not found a way
to do these things although I'm sure at least the second one is
possible.
Many thanks.

You can add your own styles for printing terms or theorems. Add the
following to your theory. It declares your own styles "no_all_prem1" and
"no_all_prem2" - you can add more if you like.
setup {*
let
fun strip_assums_all (params, Const("all",_)$Abs(a,T,t)) =
strip_assums_all ((a,T)::params, t)
| strip_assums_all (params, B) = (params, B);
fun style_parm_premise i ctxt t =
let val prems = Logic.strip_imp_prems t in
if i <= length prems
then let val (params,t) = strip_assums_all([], nth prems (i - 1))
in subst_bounds(map Free params, t) end
else error ("Not enough premises for prem" ^ string_of_int i ^
" in propositon: " ^ Syntax.string_of_term ctxt t)
end;
in
TermStyle.add_style "no_all_prem1" (style_parm_premise 1) #>
TermStyle.add_style "no_all_prem2" (style_parm_premise 2)
end
*}
Now you can go @{thm_style no_all_prem1 my_induction_thm}
Warning: I have hardly tested this!

No there is not. You can only access the full power of syntax print
translations through antiquotations.
Typically there are two kinds of documents typeset with Isabelle:
1) present the pure theory (or an Isabelle tutorial): mainly Isabelle
proof text with documenting @{text } quotations and antiquotations.
2) write a document (like a thesis) about your theories: mainly a big
@{text } quotation with heaps of antiquotations.
Cheers,
Norbert
