[isabelle-dev] Method parsing, YXML and term construction.

[Florian Haftmann]

Hi Thomas,

Isabelle internalizes expressions in two steps:

	(1) parse :: raw string (type string) -> raw term (type term)
	(2) check :: raw term (type term) -> internalized term with types
inferred etc. (type term)

It seems to me that most things you want to do can be done using (2) only:

a) read your y using Syntax.read_term
b) assemble your f and x using datatype term, placing type inference
parameters wherever suitable using Type_Infer.param
c) put the term together
d) check it using Syntax.check_term.

Hope this helps,
	Florian
