eliminate use of Thy_Info 12: TermC partially
     1 * MW: implement ML toplevel spans in official Isabelle, e.g.
     2   with separator \<^medskip> and some tool support for automated
     3   update (in "isabelle update" and/or PIDE);
     4 
     5 * MW?: rename *.sml to *.ML, potentially with tool support;
     6 
     7 * MW: clarify/eliminate Isabelle/Scala add-ons (presently unused)

    16 
    17 * MW: Skip_Proof.make_thm: theory -> term -> thm        ? could now change signature to
    18                          : Proof.context -> term -> thm
    19 * MW: Make $ISABELLE_ISAC_TEST work without sessions (please synchronise with WN)
    20 
    21 
    22 ***** some items for discussion
    23 
    24 * Clarify symmetric rule: Thm.apply_attribute Calculation.symmetric thm context (!?);
    25     ??
    26 
    27 * "fun pr_ord" is not required if used with @{make_string}, @{print}, @{print tracing};
    28     takes only static arguments ----------------^^^^^^^^^^^^^^, not value of "hd_ord (f, g)"
    29     ? are there better approximations to old output of (*1*) than with (*2*)
    30     (*1*)val _ = tracing ("hd_ord (f, g)      = " ^ ((pr_ord o hd_ord) (f, g)) );
    31     (*2*)val _ = @{print tracing}{a = "hd_ord (f, g)      = ", z = hd_ord (f, g)}(**)
    32 
    33 
    34 ***** for the few items below WN asks MW for help
    35 
    36 * postpone: ?How accomplish two user-requirements by Outer_Syntax.command \<^command_keyword>\<open>Example\<close>
    37    (1) start a Calculation with a CAS_Cmd
    38    (2) start an Example from scratch, i.e. with (Formalize.empty, References.empty)
    39    Proposals for a solution are in test/../Test_VSCode_Example.thy
    40    in subsubsection ‹Start Example with a CAS_Cmd›
    41 
    42 
    43 ***** priority of WN items is top down, most urgent/simple on top
    44 
    45 * WN: eliminate multiple get_ctxt in Solve_Step, Ctree
    46 * WN: shift code from libraryC.sml to designated destination (ThyC, etc)
    47 * WN: Know_Store.get_thes, add_thes still required for Error_Patterns, we want to eliminate thes:
    48     (1) Error_Pattern.T are already stored by MethodC -- place them in respective thys
    49     (2) Error_Pattern.fill_in stored with thm (in thes): instead introduce new Thy_Data for them.
    50         adapt Know_Store.insert_fillpats for that purpose.
    51     cf. e587c45cae0f note in Build_Thydata.thy
    52 * WN: rename type Rule.rule -> Rule.T
    53 * WN: Sub_Problem.tac_from_prog: use ctxt from pt
    54 * WN: in subst_adapt_to_type should ''bdv''(string) handled by Varialbe.declare_constraints
    55       ?why is "x" not already typed correctly (by reading strings from Formalise)?)
    56 * WN: replace tools derived from get_thes/add_thes by tools derived from current ctxt
    57 * WN: improve naming in refine.sml, m-match.sml
    58 * WN: all UnparseC with Proof.context, cleanup unparseC.sml and calls
    59 * WN: all Subst with Proof.context, cleanup unparseC.sml and calls
    60 * WN: review Prog_Tac:
    61       (*+isa==isa2*)@{term "Substitution []"};               (*Free ("Subproblem",.. ALSO Subproblem, ?!*)
    62       (*+isa==isa2*)@{term "Rewrite_Set ''norm_Rational''"}; (*Const ("Prog_Tac.Rewrite_Set",..*)
    63 
    64 * WN: Specify/formalise.sml is in BaseDefinitions/ AND Specify/  DELETE ONE VERSION
    65 * WN: Step_Specify.initialise: remove hdl in return-value, replace Step_Specify.nxt_specify_init_calc
    66       ? which uses initialise !?
    67 * WN: ? unify "no_met" with "empty_meth_id" from References.empty ?
    68 
    69 * WN: proper ML antiquotations for "Tactical.Try" etc. --- be careful about unclear situations,
    70   e.g. "Tactical.Try" vs. "Lucas_Interpreter.Try";
    71 
    72 * WN: ? Rational.Cancel_p; extend use of \<^theory> to \<^theory_context>
    73 
    74 * WN: Check/clarify Context.theory_name vs. Context.theory_long_name.
    75     Context.theory_name seems to suffice after elimination of sessions.
    76 
    77 * WN: more direct logical foundations wrt. Isabelle/HOL, eliminate many axiomatizations
    78     - quite often "axiomatization ..." can be turned into "lemma ... by auto"
    79       without further ado;
    80     - sometimes this requires to use more specific types / type classes;
    81     - sometimes this requires to use proper definitional mechanisms (e.g. 'primrec', 'fun');
    82     - a few "hard" cases will remain, to be reconsidered eventually (e.g. differentiation);
    83 
    84 * WN: rename Pos.* -- Pos.ints, Pos.spec, Pos.empty, Pos.ints_empty
    85 
    86 * WN: redesign transition from Specification to Solution: how relate 
    87     - Formalise.model with variants (e.g. VSCode_Example)
    88       reconsider separation of variants F_I, F_II, see MAWEN paper
    89     - !?! I_Model of MethodC          (fairly free sequence, dependent on Formalise.model)
    90     - !?! formal arguments of program (fixed sequence)
    91 
    92 * WN: avoid too many uses of "structure Data = Theory_Data", instead use approx. 1 data slot
    93   per ML module, with type T = ... record or tuple (e.g. see @{apply} ML antiquotation)
    94 
    95 * WN: rename *.sml to *.ML, potentially with tool support by MW;
    96 * WN: rename src/Tools/isac/ to main/ (or something else);
