combinator Option.these

adjusted examples

countable_datatype method: pre-instantiate induction rule to avoid failure with e.g. datatype a = A "b list" and b = B "a"

handle type constructors not known to be a BNF using the DEADID BNF

respect order of/additional type variables supplied by the user in fixed point constructions;

gracefully handle shadowing case (fourth step of sugar localization)

careful about constructor types w.r.t. fake context (third step of localization)

read the real types off the constant types, rather than using the fake parser types (second step of sugar localization)

tuning

use "add_type" rather than "add_types_global"

don't throw away the context when hacking the theory (first step to localize the sugar code)

tuning

introduced and used "mk_Freesss", and simplified "mk_Freess(')"

construct high-level iterator RHS

option for discarding build results, enabled in particular for Isabelle_makeall

by default, only generate one discriminator for a two-value datatype

eliminated potentially confusing terminology of Scala "layer";

merged

tuned proofs;

discontinued obsolete fork_mono to loosen some brakes -- NB: TTY interaction has Goal.future_proofs disabled due to missing Future.worker_task;

honor mixfix specifications

code indentation

print timing information

adapted example

check type variables on rhs

proper subsexp projection of Isabelle_Markup.Path, in correspondence to 5d0cd770828e;

added tooltip to reveal jEdit platform file name;

commented out slow examples again

fixed (n + 1)st bug in "mk_exhaust_tac" -- arose with uncurried constructors

fixed "mk_exhaust_tac" for the nth time

updated README

ported "Misc_Codata" to new syntax

ported "Misc_Data" to new syntax

error message only in case of an error

do not trivialize important internal theorem in quick_and_dirty mode

merged

made "mk_case_eq_tac" work in the case where the first constructor is an "alternate" constructor (in which case its discriminator paradoxically starts with a negation)

tuning (systematic 1-based indices)

reindented code

added TODO

tell "select_prem_tac" not to thin any further premisses -- the "rotate_tac" otherwise confuses it

fixed "mk_alternate_disc_def_tac" in the case where the constructors are swapped compared with the common Nil/Cons case

don't get confused by extraneous premisses

added a check

misc tuning;

no need to wait 3h on macbroy30 (unlike former macbroy6, cf. 6e5b994070c1);

more conservative rechecking of processed constraints in subtyping constraint simplification
