11 * MW: Skip_Proof.make_thm: theory -> term -> thm ? could now change signature to
12 : Proof.context -> term -> thm
15 ***** some items for discussion
17 * Clarify symmetric rule: Thm.apply_attribute Calculation.symmetric thm context (!?);
20 * "fun pr_ord" is not required if used with @{make_string}, @{print}, @{print tracing};
21 takes only static arguments ----------------^^^^^^^^^^^^^^, not value of "hd_ord (f, g)"
22 ? are there better approximations to old output of (*1*) than with (*2*)
23 (*1*)val _ = tracing ("hd_ord (f, g) = " ^ ((pr_ord o hd_ord) (f, g)) );
24 (*2*)val _ = @{print tracing}{a = "hd_ord (f, g) = ", z = hd_ord (f, g)}(**)
27 ***** for the few items below WN asks MW for help
29 * MW: make Outer_Syntax.command..‹problem› a model for ..\<open>Example\<close>
30 The model should demonstrate, how an ML syntax error is indicated in place
31 (in the string after \<^keyword>\<open>Given\<close> etc) and not on the definition as a whole.
32 - in MathEngBasic/problem "Outer_Syntax.command \<^command_keyword>\<open>problem\<close>" there are writeln
33 and comments with testdata from "problem pbl_bieg : "Biegelinien"" in Biegelinie.thy
34 - in MathEngBasic/problem there is guesswork ("TODO") how to reorganise "fun prep_input_PIDE"
35 such that errors in "Given" etc are indicated WITHIN the term.
37 * MW: In Outer_Syntax.command..‹Example› help: is there a quick fix
38 for successfully replacing hacked Problem.parse_cas by parse_references_input?
39 (a) In addition to replacing Problem.parse_cas: How implement the optional parser:
40 - Example "Diff_App/No.123 a" + NONE
41 - Example "Diff_App/No.123 a" + SOME (probl_id, model_input, refs_input)
42 i.e. we expect ISAC to present an empty template "Problem..Solution", but as a whole, to the user;
43 see VSCode_Example.thy subsubsection \<open>Specification step by step\<close>
44 How get Token.src for testing purposes?
45 How can Scan.* be traced?
46 (Tracing should help understanding Problem.parse_cas, Problem.parse_model_input which involve Scan.* )
48 * ?How represent items, which have not yet been input?
49 Note: For the purpose of user-guidance the format of requested input should be indicated!
50 - proposal for how to indicate requested input: in VSCode_Example.thy subsubsection \<open>Empty Specification>
51 - the trial with <fun is_empty> in Calculation.thy makes the question more precise:
52 better hack parsers or better work on ML_Syntax?
54 * ?How accomplish two user-requirements by Outer_Syntax.command \<^command_keyword>\<open>Example\<close>
55 (1) start a Calculation with a CAS_Cmd
56 (2) start an Example from scratch, i.e. with (Formalize.empty, References.empty)
57 Proposals for a solution are in test/../Test_VSCode_Example.thy
58 subsubsection ‹Start Example with a CAS_Cmd›
61 ***** priority of WN items is top down, most urgent/simple on top
63 * What is the idea behind KEStore_Elems.add_thes? How to do it properly in current Isabelle?
64 See notes in Build_Thydata.thy.
65 https://static.miraheze.org/isacwiki/0/04/Isac-docu.pdf distinguishes
66 several kinds of ISAC users, in particular "math author (Mathematik-Autor)" and
67 "course designer (Kurs-Designer)". The latter just adds examples which re-use existing
68 knowledge designed by the former. KEStore_Elems.add_thes is an interface for the latter.
69 KEStore_Elems.get_thes and KEStore_Elems.add_thes are ONLY required for the Lucas-Interpreter
70 retrieving Thm and Rls from string-identifiers (which do NOT indicate the theory of) --
71 -- get_thes and add_thes are the main reason for (b)
72 So: How can KEStore_Elems.get_thes and KEStore_Elems.add_thes be replaced in current Isabelle?
74 * WN: rename structure KEStore_Elems --> Know_Store
75 * WN: Step_Specify.initialisePIDE: remove hdl in return-value, replace Step_Specify.nxt_specify_init_calc
76 ? which uses initialisePIDE !?
77 * WN: ? unify "no_met" with "empty_meth_id" from References.empty ?
79 * WN: proper ML antiquotations for "Tactical.Try" etc. --- be careful about unclear situations,
80 e.g. "Tactical.Try" vs. "Lucas_Interpreter.Try";
82 * WN: ? Rational.Cancel_p; extend use of \<^theory> to \<^theory_context>
84 * WN: Avoid Thm.get_name_hint and use Global_Theory.get_thm instead, get theory from References.T
85 and push theory through as argument of respective functions.
87 * WN: Eliminate Thy_Info.get_theory eventually: should take theory from ancestory
88 within current context.
89 cf. e587c45cae0f note in Build_Thydata.thy
91 * WN: Check/clarify Context.theory_name vs. Context.theory_long_name.
92 present ISAC assumes 2 sessions in the MathEngine, Specify and Interpret,
93 and all Isac_Knowledge is in session Isac.
94 So Context.theory_name suffices
96 * WN: more direct logical foundations wrt. Isabelle/HOL, eliminate many axiomatizations
97 - quite often "axiomatization ..." can be turned into "lemma ... by auto"
99 - sometimes this requires to use more specific types / type classes;
100 - sometimes this requires to use proper definitional mechanisms (e.g. 'primrec', 'fun');
101 - a few "hard" cases will remain, to be reconsidered eventually (e.g. differentiation);
103 * WN: eliminate argument theory from Interpret/*, e.g. (LI_Tool.tac_from_prog + see TODO.thy)
104 * WN: rename Pos.* -- Pos.ints, Pos.spec, Pos.empty, Pos.ints_empty
106 * WN: redesign transition from Specification to Solution: how relate
107 - Formalise.model with variants (e.g. VSCode_Example)
108 reconsider separation of variants F_I, F_II, see MAWEN paper
109 - !?! I_Model of MethodC (fairly free sequence, dependent on Formalise.model)
110 - !?! formal arguments of program (fixed sequence)
