1 * MW: make Outer_Syntax.command \<^command_keyword>\<open>problem\<close> a model for ..\<open>Example\<close>
2 An ML syntax error should be indicated in place (in the string after \<^keyword>\<open>Given\<close> etc)
3 and not on the definition as a whole.
4 - in MathEngBasic/problem "Outer_Syntax.command \<^command_keyword>\<open>problem\<close>" there are writeln
5 and comments with testdata from "problem pbl_bieg : "Biegelinien"" in Biegelinie.thy
6 - in MathEngBasic/problem there is guesswork ("TODO") how to reorganise "fun prep_input_PIDE"
7 such that errors in "Given" etc are indicated WITHIN the term.
9 * ?MW?: In Outer_Syntax.command \<^command_keyword>\<open>Example\<close> is there a quick fix
10 for successfully replacing hacked Problem.parse_cas by parse_references_input?
11 (a) In addition to replacing Problem.parse_cas: How implement the optional parser:
12 - Example "Diff_App/No.123 a" + NONE
13 - Example "Diff_App/No.123 a" + SOME (probl_id, model_input, refs_input)
14 i.e. we expect ISAC to present an empty template "Problem..Solution", but as a whole, to the user;
15 see VSCode_Example.thy subsubsection \<open>Specification step by step\<close>
16 How get Token.src for testing purposes?
17 How can Scan.* be traced?
18 (Tracing should help understanding Problem.parse_cas, Problem.parse_model_input which involve Scan.*)
20 * MW: check uses of Unsynchronized.ref vs. Synchronized.var;
22 * MW: clarify/eliminate Isabelle/Scala add-ons (presently unused)
24 diff -r /home/makarius/isabelle/repos-Isabelle2021/src/Pure/build-jars ./src/Pure/build-jars
26 > src/Tools/isac/BridgeJEdit/isac.scala
28 diff -r /home/makarius/isabelle/repos-Isabelle2021/src/Pure/Tools/scala_project.scala ./src/Pure/Tools/scala_project.scala
30 > "src/Tools/isac/etc" -> Path.explode("isabelle.isac"),
32 * Eliminate Thy_Info.get_theory eventually: should take theory from ancestory
33 within current context.
34 cf. e587c45cae0f note in Build_Thydata.thy
36 * Clarify symmetric rule: Thm.apply_attribute Calculation.symmetric thm context (!?);
39 * KEStore_Elems: Should we eliminate union_overwrite and use standard namespace merge?
40 (Exception: rlss with its special cross-theory merge.)
41 ? how adapt the different signatures ?
42 union_overwrite: ('a * 'a -> bool) -> 'a list -> 'a list -> 'a list
43 merge : ('a * 'a -> bool) -> 'a list * 'a list -> 'a list
45 * What is the purpose of "#numeral" instead of plain numeral?
48 * Check/clarify Context.theory_name vs. Context.theory_long_name.
49 present ISAC assumes 2 sessions in the MathEngine, Specify and Interpret,
50 and all Isac_Knowledge is in session Isac.
51 So Context.theory_name suffices
53 * Eliminate mutable Rewrite_Ord.rew_ord' (!?);
54 shall be done in connection with cf. e587c45cae0f note in Build_Thydata.thy
56 * What is the idea behind KEStore_Elems.add_thes? How to do it properly in current Isabelle?
57 https://static.miraheze.org/isacwiki/0/04/Isac-docu.pdf distinguishes
58 several kinds of ISAC users, in particular "math author (Mathematik-Autor)" and
59 "course designer (Kurs-Designer)". The latter just adds examples which re-use existing
60 knowledge designed by the former. KEStore_Elems.add_thes is an interface for the latter.
62 * WN: proper ML antiquotations for "Tactical.Try" etc. --- be careful about unclear situations,
63 e.g. "Tactical.Try" vs. "Lucas_Interpreter.Try";
65 * WN: Avoid Thm.get_name_hint and use Global_Theory.get_thm instead, get theory from References.T
66 and push theory through as argument of respective functions.
68 * WN: more direct logical foundations wrt. Isabelle/HOL, eliminate many axiomatizations
69 - quite often "axiomatization ..." can be turned into "lemma ... by auto"
71 - sometimes this requires to use more specific types / type classes;
72 - sometimes this requires to use proper definitional mechanisms (e.g. 'primrec', 'fun');
73 - a few "hard" cases will remain, to be reconsidered eventually (e.g. differentiation);
75 * WN: "fun pr_ord" is not required if used with @{make_string}, @{print}, @{print tracing};
76 takes only static arguments ----------------^^^^^^^^^^^^^^, not value of "hd_ord (f, g)"
77 ? are there better approximations to old output of (*1*) than with (*2*)
78 (*1*)val _ = tracing ("hd_ord (f, g) = " ^ ((pr_ord o hd_ord) (f, g)) );
79 (*2*)val _ = @{print tracing}{a = "hd_ord (f, g) = ", z = hd_ord (f, g)}(**)
82 * WN: eliminate global flags like "trace_on", replace Unsynchronized.ref by
85 val rewrite_trace = Attrib.setup_config_bool \<^binding>\<open>rewrite_trace\<close> (K false);
88 * WN: redesign transition from Specification to Solution: how relate
89 - Formalise.model with variants (e.g. VSCode_Example)
90 reconsider separation of variants F_I, F_II, see MAWEN paper
91 - !?! I_Model of MethodC (fairly free sequence, dependent on Formalise.model)
92 - !?! formal arguments of program (fixed sequence)
94 * WN: ?How represent items, which have not yet been input?
95 Note: For the purpose of user-guidance the format of requested input should be indicated!
96 - proposal for how to indicate requested input: in VSCode_Example.thy subsubsection \<open>Empty Specification>
97 - this proposal presumable involves hacking of parsers -- is there a better way?
98 - implementation and tests have solution for (a) above as a prerequisite.
100 * WN: rename in Formalise: type spec = Model_Def.form_spec;
101 type refs = Model_Def.form_refs;
102 * WN: rename in Know_Store: get_ptyps, add_pbls
104 * WN: as soon as parsing in Outer_Syntax.command..‹Example› works, implement in Calculation
105 - init_ctree, update_status, check_input
