remove Hoare dependency from Fold.thy

added specific 'spark_open_vcg' and 'spark_open_siv' with formal management of corresponding source files;

turned 'boogie_open' into thy_load command, without any declarations of 'uses';

tuned signature;

clarified type Token.file;

expand all files uniformly;

added build option -l (list files);

prefer classic take_prefix/take_suffix over chop_while (cf. 0659e84bdc5f);

more basic file dependencies -- no load command here;

tuned signature (again, cf. ff9cd47be39b);

updated Thy_Load.check_thy;

simplified Thy_Load.check_thy (again) -- no need to pass keywords nor find files in body text;

tuned signature;

simplified Thy_Load.provide: do not store full path;

prefer ML_file over old uses; updated generated files;

merged

abstracted lemmas

prefer ML_file over old uses;

prefer ML_file over old uses;

'ML_file' evaluates ML text from a file directly within the theory, without predeclaration via 'uses';

add keywords of this node as well (e.g. relevant for Pure.thy);

tuned;

tuned message -- dynamic loading happens routinely, e.g. in TTY/PG interaction;

discontinued separate list of required files -- maintain only provided files as they occur at runtime; tuned signature;

find files via load commands within theory text; clarified Thy_Load.with_thy_text, simplified Thy_Load.check_thy;

clarified global get_recent_syntax: session always has its base_syntax, but it might be absent itself;

pass syntax through check_thy;

use Thy_Header.read on explicit text only -- potentially via File.read, not Scan.byte_reader; tuned signatures;

clarified Parse.path vs. Parse.explode -- prefer errors in proper transaction context;

tuned;

clarified bootstrapping of Pure;

tuned errors;

prefer File.full_path in accordance to check_file;

more standard Thy_Load.check_thy for Pure.thy, relying on its header; pass uses and keywords from Thy_Load.check_thy to Thy_Info.load_thy; clarified 'ML_file' wrt. Thy_Load.require/provide, which is also relevant for Thy_Load.all_current;

updated Thy_Load.check_thy;

refined Thy_Load.check_thy: find more uses in body text, based on keywords; refined Thy_Info.require_thy(s): cumulate additional keywords; slightly more value-oriented type Keywords.keywords;

more direct cumulation of (sparse) keywords; discontinued slightly odd patching of Pure keywords; tuned signature;

some support for thy_load_commands; clarified signatures;

tuned signature;

clarified initialization of Thy_Load, Thy_Info, Session;

tuned;

more robust cleaning of "% tag" and "-- cmt";

some support for inlining file content into outer syntax token language;

tuned comment;

tuned;

added keyword kind "thy_load" (with optional list of file extensions);

updated generated files;

more strict syntax, according to manual;

abstracted lemma

retain unknown options within preferences; tuned print;

more comprehensible platform family name;

tuned message;

fewer components, more roots;

actually remove makeall (cf. 292b97e17fb7);

tuned;

Backed out changeset ec82c33c75f8;

Typo fixed.

updated to new init_components, hoping that mira can digest that;

some explanations on component categories;

specific cygwin components;

obsolete;

some explanations on isabelle components;

some grouping of components;

renamed components to components_old, to make room for some directory of the same name;

minor robustification;

added "isabelle components" tool;

tuned;

direct support for component forests via init_components; explicit ISABELLE_COMPONENTS_MISSING;

allow to provide external ISABELLE_IDENTIFIER for repository clone -- potentially relevant for isatest and mira; clarified spaces in file names -- ISABELLE_HOME is non-critical after abolishment of "make";

tuned;

tuned;

updated component repository;

updates on 32 bit vs. 64 bit platforms; added Mountain Lion; dropped Leopard; tuned;

updated to jedit_build-20120813, pointing to another contrib directory as a change;

merged

tuned proofs;

look in current directory first before looking up includes in the TPTP directory, as required by Geoff

prefer eta-expanded code equations for fold, to accomodate tail recursion optimisation in Scala

more robust multi-platform support;

updated to jdk-7u6 and jedit_build-20120813 -- NB: plain Isabelle/Scala still happens to work with jdk-6;

support for jdk-7u6 component;

Clarification: free variables allowed in interpreted locale instances.

Turned into Admin tool download_components.

tuned;

tuned;

some updates of "Presenting theories", using mkroot/build instead of former mkdir/make/usedir (which are still present in "Misc");

tuned;

fixed handling of "int" in the wake of its port to the quotient package

removed dead code

merged

Added various options, notably -c to download components listed in Admin/components. Also, curl instead of wget.

ignore some administrative files on newer Mercurial versions as well;

some support for persistent user preferences;

merged

explicit document_output directory, without implicit purge of default in ISABELLE_BROWSER_INFO;

more direct interpretation of document_variants for build (unchanged for usedir);

tone down "z3_tptp", now that Z3 (starting with 4.1) no longer supports TPTP TFF0

fixed then-else confusion

tweak Vampire setup in the light of new evaluation

improved set of reconstructor methods

warn users about unused "using" facts

be less aggressive at kicking out chained facts

recognize bus errors as crash

consider removing chained facts last, so that they're more likely to be kept

clarified format of etc/options: only declarations, not re-definitions;

check_errors for cumulative session content;

even more defensive path expansion (see also 8d381fdef898);

support for 'typ' with explicit sort constraint;

added jedit option -d;

always retain doc-src (as regular component);
