* Toplevel theorem statements have been simplified as follows: 

13 

14 
theorems ~> lemmas 

15 
schematic_lemma ~> schematic_goal 

16 
schematic_theorem ~> schematic_goal 

17 
schematic_corollary ~> schematic_goal

19 
Commandline tool "isabelle update_theorems" updates theory sources 

20 
accordingly. 

21 

61338  22 
* Toplevel theorem statement 'proposition' is another alias for 
23 
'theorem'. 

24 

61579  25 
* Syntax for formal comments " text" now also supports the symbolic 
26 
form "\<comment> text". Commandline tool "isabelle update_cartouches c" helps 

27 
to update old sources.

60986  39 
* IDE support for the sourcelevel debugger of Poly/ML, to work with 
60984  40 
Isabelle/ML and official Standard ML. Configuration option "ML_debugger" 
41 
and commands 'ML_file_debug', 'ML_file_no_debug', 'SML_file_debug', 

42 
'SML_file_no_debug' control compilation of sources with debugging 

43 
information. The Debugger panel allows to set breakpoints (via context 

44 
menu), step through stopped threads, evaluate local ML expressions etc. 

45 
At least one Debugger view needs to be active to have any effect on the 

46 
running ML program. 

47 

61173  48 
* The main Isabelle executable is managed as singleinstance Desktop 
49 
application uniformly on all platforms: Linux, Windows, Mac OS X. 

61170  50 

61198  51 
* The text overview column (status of errors, warnings etc.) is updated 
52 
asynchronously, leading to much better editor reactivity. Moreover, the 

53 
full document node content is taken into account. 

54 

61729  55 
* The State panel manages explicit proof state output. The jEdit action 
56 
"isabelle.updatestate" (shortcut S+ENTER) triggers manual update 

57 
according to cursor position. 

58 

59 
* The Output panel no longer shows proof state output by default, to 

60 
avoid GUI overcrowding. INCOMPATIBILITY, use the State panel instead or 

61 
enable option "editor_output_state". 

61215  62 

61483  63 
* Action "isabelleemph" (with keyboard shortcut C+e LEFT) controls 
64 
emphasized text style; the effect is visible in document output, not in 

65 
the editor. 

66 

67 
* Action "isabellereset" now uses keyboard shortcut C+e BACK_SPACE, 

68 
instead of former C+e LEFT.

87 
that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  88 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
89 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  90 
standard Isabelle fonts provide glyphs to render important control 
91 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

61653  94 
(outer syntax with command keywords etc.). This may be used in the short 
61748  95 
form \<^theory_text>\<open>...\<close>. @{theory_text [display]} supports option "indent".

103

104 

61595  105 
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with 
106 
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using 

107 
standard LaTeX macros of the same names.

110 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  111 
text. Commandline tool "isabelle update_cartouches t" helps to update 
112 
old sources, by approximative patching of the content of string and 

113 
cartouche tokens seen in theory sources.

61471  121 
* HTML presentation uses the standard IsabelleText font and Unicode 
122 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  123 
print mode "HTML" loses its special meaning. 
61471  124 

61463  125 
* Commands 'paragraph' and 'subparagraph' provide additional section 
126 
headings. Thus there are 6 levels of standard headings, as in HTML. 

127 

128 
* Text is structured in paragraphs and nested lists, using notation that 

129 
is similar to Markdown. The control symbols for list items are as 

130 
follows: 

131 

132 
\<^item> itemize 

133 
\<^enum> enumerate 

134 
\<^descr> description 

135 

136 
* Command 'text_raw' has been clarified: input text is processed as in 

137 
'text' (with antiquotations and control symbols). The key difference is 

138 
the lack of the surrounding isabelle markup environment in output.

* Local goals ('have', 'show', 'hence', 'thus') allow structured 
61733  160 
rule statements like fixes/assumes/shows in theorem specifications, but 
161 
the notation is postfix with keywords 'if' (or 'when') and 'for'. For

166 
for x :: 'a and y :: 'a 

167 
<proof> 

168 

60449  169 
The local assumptions are bound to the name "that". The result is 
170 
exported from context of the statement as usual. The above roughly 

60414  171 
corresponds to a raw proof block like this: 
172 

173 
{ 

174 
fix x :: 'a and y :: 'a 

60449  175 
assume that: "A x" "B y" 
60414  176 
have "C x y" <proof>

182 

61733  183 
* Assumptions ('assume', 'presume') allow structured rule statements 
184 
using 'if' and 'for', similar to 'have' etc. above. For example: 

61658  185 

186 
assume result: "C x y" 

187 
if "A x" and "B y" 

188 
for x :: 'a and y :: 'a 

189 

190 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

191 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

192 

193 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

194 
only effects propositions according to actual use of variables. For 

195 
example: 

196 

197 
assume "A x" and "B y" for x and y 

198 

199 
is equivalent to: 

200 

201 
assume "\<And>x. A x" and "\<And>y. B y" 

202 

60595  203 
* The meaning of 'show' with Pure rule statements has changed: premises 
204 
are treated in the sense of 'assume', instead of 'presume'. This means, 

205 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

206 

207 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

208 

209 
or: 

210 

211 
show "C x" if "A x" "B x" for x 

212 

213 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

214 

215 
show "C x" when "A x" "B x" for x 

216 

60406  217 
* New command 'supply' supports fact definitions during goal refinement 
218 
('apply' scripts). 

219 

60459  220 
* New command 'consider' states rules for generalized elimination and 
221 
case splitting. This is like a toplevel statement "theorem obtains" used 

222 
within a proof body; or like a multibranch 'obtain' without activation 

223 
of the local context elements yet. 

224 

60455  225 
* Proof method "cases" allows to specify the rule as first entry of 
226 
chained facts. This is particularly useful with 'consider': 

227 

228 
consider (a) A  (b) B  (c) C <proof> 

229 
then have something 

230 
proof cases 

231 
case a 

232 
then show ?thesis <proof> 

233 
next 

234 
case b 

235 
then show ?thesis <proof> 

236 
next 

237 
case c 

238 
then show ?thesis <proof> 

239 
qed 

240 

60565  241 
* Command 'case' allows fact name and attribute specification like this: 
242 

243 
case a: (c xs) 

244 
case a [attributes]: (c xs) 

245 

246 
Facts that are introduced by invoking the case context are uniformly 

247 
qualified by "a"; the same name is used for the cumulative fact. The old 

248 
form "case (c xs) [attributes]" is no longer supported. Rare 

249 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

250 
and always put attributes in front.

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  287 
is marked as legacy, and will be removed eventually. The proof method 
288 
"goals" achieves a similar effect within regular Isar; often it can be 

289 
done more adequately by other means (e.g. 'consider').

* Nesting of Isar goal structure has been clarified: the context after 
292 
the initial backwards refinement is retained for the whole proof, within 

293 
all its context sections (as indicated via 'next'). This is e.g. 

294 
relevant for 'using', 'including', 'supply':

uniformly via "context begin qualified definition ... end" instead of 

428 
oldstyle "hide_const (open) ...". Consequently, both the defined 

429 
constant and its defining fact become qualified, e.g. Option.is_none and 

430 
Option.is_none_def. Occasional INCOMPATIBILITY in applications.

*** Document preparation *** 
803 

804 
* Document markup commands 'chapter', 'section', 'subsection', 

805 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

806 
context, even before the initial 'theory' command. Obsolete proof 

807 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

808 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

809 
instead. The old 'header' command is still retained for some time, but 

810 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

811 
update_header"). Minor INCOMPATIBILITY. 

812 

60009  813 
* Official support for "tt" style variants, via \isatt{...} or 
814 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

815 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

816 
as argument to other macros (such as footnotes). 

817 

818 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

819 
style. 

820 

821 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

822 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

823 

59951  824 
* Diagnostic commands and document markup commands within a proof do not 
825 
affect the command tag for output. Thus commands like 'thm' are subject 

826 
to proof document structure, and no longer "stick out" accidentally. 

827 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

828 
tags. Potential INCOMPATIBILITY in exotic situations. 

829 

830 
* System option "pretty_margin" is superseded by "thy_output_margin", 

831 
which is also accessible via document antiquotation option "margin". 

832 
Only the margin for document output may be changed, but not the global 

833 
pretty printing: that is 76 for plain console output, and adapted 

834 
dynamically in GUI frontends. Implementations of document 

835 
antiquotations need to observe the margin explicitly according to 

836 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

1015 
cos, tan, exp, Ln, Arctan, Arcsin, Arccos. Ported from HOL Light. 

1016 

1017 
* The factorial function, "fact", now has type "nat => 'a" (of a sort 

1018 
that admits numeric types including nat, int, real and complex. 

1019 
INCOMPATIBILITY: an expression such as "fact 3 = 6" may require a type 

1020

1021 
unsatisfactory. If a type conversion is still necessary, then use 

1022 
"of_nat (fact k)" or "real_of_nat (fact k)".

1025 
"nat o ceiling" instead. A few of the lemmas have been retained and

* Subtle change of name space policy: undeclared entries are now 
1129

internal name. This mainly affects Name_Space.intern (and derivatives), 

1131 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60010  1132 
contemporary applications use the strict Name_Space.check (and

1220 

57504  1221 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1222 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1223 
variable. Locale assumptions and chained facts containing "x" 

1224 
continue to be useful. The new method "hypsubst_thin" and the 

1225 
configuration option "hypsubst_thin" (within the attribute name space) 

1226 
restore the previous behavior. INCOMPATIBILITY, especially where 

1227 
induction is done after these methods or when the names of free and 

1228 
bound variables clash. As first approximation, old proofs may be 

1229 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1230 

56232  1231 
* More static checking of proof methods, which allows the system to 
1232 
form a closure over the concrete syntax. Method arguments should be 

1233 
processed in the original proof context as far as possible, before 

1234 
operating on the goal state. In any case, the standard discipline for 

1235 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1236 
number that is out of range produces an empty result sequence, not an 

1237 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1238 
proof tools. 

1239 

57452  1240 
* Lexical syntax (inner and outer) supports text cartouches with 
1241 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1242 
supports input via ` (backquote). 

1243 

1244 
* The outer syntax categories "text" (for formal comments and document 

1245 
markup commands) and "altstring" (for literal fact references) allow 

1246 
cartouches as well, in addition to the traditional mix of quotations. 

1247 

1248 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1249 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1250

57452  1251 
Minor INCOMPATIBILITY. 
1252 

1253 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1254

1255 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1256

*** Pure ***

57504  1336 
* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
1337 
been discontinued to avoid the danger of nontrivial axiomatization 

1338 
that is not immediately visible. INCOMPATIBILITY, use regular 

1339 
'instance' command with proof. The required OFCLASS(...) theorem 

1340 
might be postulated via 'axiomatization' beforehand, or the proof 

1341 
finished trivially if the underlying class definition is made vacuous 

1342 
(without any assumptions). See also Isabelle/ML operations 

1343 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

1344 
Axclass.arity_axiomatization. 

1345 

56245  1346 
* Basic constants of Pure use more conventional names and are always 
1347 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1348 
consequences, notably for tools in Isabelle/ML. The following 

1349 
renaming needs to be applied: 

1350 

1351 
== ~> Pure.eq 

1352 
==> ~> Pure.imp 

1353 
all ~> Pure.all 

1354 
TYPE ~> Pure.type 

1355 
dummy_pattern ~> Pure.dummy_pattern 

1356 

1357 
Systematic porting works by using the following theory setup on a 

1358 
*previous* Isabelle version to introduce the new name accesses for the 

1359 
old constants: 

1360 

1361 
setup {* 

1362 
fn thy => thy 

1363 
> Sign.root_path 

1364 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1365 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1366 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1367 
> Sign.restore_naming thy 

1368 
*} 

1369 

1370 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1371 
Later the application is moved to the current Isabelle version, and 

1372 
the auxiliary aliases are deleted.

55152  1378 
* Obsolete attribute "standard" has been discontinued (legacy since 
1379 
Isabelle2012). Potential INCOMPATIBILITY, use explicit 'for' context 

1380 
where instantiations with schematic variables are intended (for 

1381 
declaration commands like 'lemmas' or attributes like "of"). The 

1382 
following temporary definition may help to port old applications: 

1383 

1384 
attribute_setup standard = 

1385 
"Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))" 

1386 

55001  1387 
* More thorough check of proof context for goal statements and 
55006  1388 
attributed fact expressions (concerning background theory, declared 
1389 
hyps). Potential INCOMPATIBILITY, tools need to observe standard 

1390 
context discipline. See also Assumption.add_assumes and the more 

1391 
primitive Thm.assume_hyps.
