(* Some checks for X-Symbol behaviour.

(* Thu Sep 25 16:26:47 BST 2030.
Problem reported by Norbert Schirmer <norbert.schirmer@web.de>
Currently, superscript output highlighting seems broken anyway? *)
consts silly:: "'a => 'a => 'a" ("_\<^sup>_" [1000,1000] 1000)
consts k:: 'a
term "a\<^sup>b" (* b should be a blue variable *)
term "a\<^sup>k" (* k should be a black constant *)
(* 28.8.02: bug in pg-remove-specials broke this; now fixed *)
lemma "A ==> A" . -- OK
consts A :: bool
lemma "A ==> A" . -- "xsymbols not displayed?"
(* Test electric token input: writing a token
like \ <alpha> (without space, \<alpha>) should immediately
replace it. *)
constdefs
P1 :: bool ("P\<^sub>1") (* subscript *)
"P\<^sub>1 == True"
P2 :: bool ("P\<^sup>2") (* superscript *)
"P\<^sup>2 == True"
(* Buglet here: if we enable x-sym during scripting,
goals/response flks are not updated, so xsyms
do not appear in output windows. Stoping/starting
prover fixes.
*)
theorem "P\<^sub>1 \<and> P\<^sup>2"; (* check fonts in goals window *)
by (simp add: P1_def P2_def) (* .. and response window *)
consts
"P\<^sup>\<alpha>" :: bool (* superscript of a token char *)
"\<^bold>X" :: bool (* bold character *)
(* test: using a symbol as a subscript *)
(* 9.3.03: this causes nasty prob with pre-command hook,
x-symbol-invisitiblity-spec type error, at least
during editing. *)
consts
intof :: "nat \<Rightarrow> int" ("_\<^sub>\<int>" 50)
mynat :: nat ("\<gamma>")
constdefs
myint :: int
"myint == \<gamma>\<^sub>\<int>"
(*
Another X-Symbol oddity: sometimes the _first_ buffer to
be visited displays _some_ characters as \2xx, e.g.
for \<circ>. But subsequent buffers to be visited work
fine. Problem is stable for turning x-symbol on/off.
Revisting the first buffer cures the problem.
Update: May be inherent problem with non-Mule version of
X-Symbol (CW suggests)
