* 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.

* 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 

61218  55 
* The State panel manages explicit proof state output, with jEdit action 
56 
"isabelle.updatestate" (shortcut S+ENTER) to trigger update according 

61604  57 
to cursor position. 
58 

59 
* The Output panel no longer shows proof state output by default. This 

60 
reduces resource requirements of prover time and GUI space. 

61 
INCOMPATIBILITY, use the State panel instead or enable option 

62 
"editor_output_state". 

61215  63 

61483  64 
* Action "isabelleemph" (with keyboard shortcut C+e LEFT) controls 
65 
emphasized text style; the effect is visible in document output, not in 

66 
the editor. 

67 

68 
* Action "isabellereset" now uses keyboard shortcut C+e BACK_SPACE, 

69 
instead of former C+e LEFT.

that is a cartouche: \<^name>\<open>...\<close> is equivalent to @{name \<open>...\<close>} and 
61595  89 
\<open>...\<close> without control symbol is equivalent to @{cartouche \<open>...\<close>}. 
90 
\<^name> without following cartouche is equivalent to @{name}. The 

61501  91 
standard Isabelle fonts provide glyphs to render important control 
92 
symbols, e.g. "\<^verbatim>", "\<^emph>", "\<^bold>".

103 

61595  104 
* Antiquotations @{noindent}, @{smallskip}, @{medskip}, @{bigskip} with 
105 
corresponding control symbols \<^noindent>, \<^smallskip>, \<^medskip>, \<^bigskip> specify spacing formally, using 

106 
standard LaTeX macros of the same names.

109 
Consequently, \<open>...\<close> without any decoration prints literal quasiformal 
61492  110

111 
old sources, by approximative patching of the content of string and 

112 
cartouche tokens seen in theory sources.

61471  120 
* HTML presentation uses the standard IsabelleText font and Unicode 
121 
rendering of Isabelle symbols like Isabelle/Scala/jEdit. The former 

61488  122 
print mode "HTML" loses its special meaning. 
61471  123 

61463  124 
* Commands 'paragraph' and 'subparagraph' provide additional section 
125 
headings. Thus there are 6 levels of standard headings, as in HTML. 

126 

127 
* Text is structured in paragraphs and nested lists, using notation that 

128 
is similar to Markdown. The control symbols for list items are as 

129 
follows: 

130 

131 
\<^item> itemize 

132 
\<^enum> enumerate 

133 
\<^descr> description 

134 

135 
* Command 'text_raw' has been clarified: input text is processed as in 

136 
'text' (with antiquotations and control symbols). The key difference is 

137 
the lack of the surrounding isabelle markup environment in output.

165 
for x :: 'a and y :: 'a 

166 
<proof> 

167 

60449  168 
The local assumptions are bound to the name "that". The result is 
169 
exported from context of the statement as usual. The above roughly 

60414  170 
corresponds to a raw proof block like this: 
171 

172 
{ 

173 
fix x :: 'a and y :: 'a 

60449  174 
assume that: "A x" "B y" 
60414  175

181 

61658  182 
* Assumptions ('assume', 'presume') allow structured statements using 
183 
'if' and 'for', similar to 'have' etc. above. For example: 

184 

185 
assume result: "C x y" 

186 
if "A x" and "B y" 

187 
for x :: 'a and y :: 'a 

188 

189 
This assumes "\<And>x y::'a. A x \<Longrightarrow> B y \<Longrightarrow> C x y" and produces a general 

190 
result as usual: "A ?x \<Longrightarrow> B ?y \<Longrightarrow> C ?x ?y". 

191 

192 
Vacuous quantification in assumptions is omitted, i.e. a forcontext 

193 
only effects propositions according to actual use of variables. For 

194 
example: 

195 

196 
assume "A x" and "B y" for x and y 

197 

198 
is equivalent to: 

199 

200 
assume "\<And>x. A x" and "\<And>y. B y" 

201 

60595  202 
* The meaning of 'show' with Pure rule statements has changed: premises 
203 
are treated in the sense of 'assume', instead of 'presume'. This means, 

204 
a goal like "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" can be solved completely as follows: 

205 

206 
show "\<And>x. A x \<Longrightarrow> B x \<Longrightarrow> C x" 

207 

208 
or: 

209 

210 
show "C x" if "A x" "B x" for x 

211 

212 
Rare INCOMPATIBILITY, the old behaviour may be recovered as follows: 

213 

214 
show "C x" when "A x" "B x" for x 

215 

60406  216 
* New command 'supply' supports fact definitions during goal refinement 
217 
('apply' scripts). 

218 

60459  219 
* New command 'consider' states rules for generalized elimination and 
220 
case splitting. This is like a toplevel statement "theorem obtains" used 

221 
within a proof body; or like a multibranch 'obtain' without activation 

222 
of the local context elements yet. 

223 

60455  224 
* Proof method "cases" allows to specify the rule as first entry of 
225 
chained facts. This is particularly useful with 'consider': 

226 

227 
consider (a) A  (b) B  (c) C <proof> 

228 
then have something 

229 
proof cases 

230 
case a 

231 
then show ?thesis <proof> 

232 
next 

233 
case b 

234 
then show ?thesis <proof> 

235 
next 

236 
case c 

237 
then show ?thesis <proof> 

238 
qed 

239 

60565  240 
* Command 'case' allows fact name and attribute specification like this: 
241 

242 
case a: (c xs) 

243 
case a [attributes]: (c xs) 

244 

245 
Facts that are introduced by invoking the case context are uniformly 

246 
qualified by "a"; the same name is used for the cumulative fact. The old 

247 
form "case (c xs) [attributes]" is no longer supported. Rare 

248 
INCOMPATIBILITY, need to adapt uses of case facts in exotic situations, 

249 
and always put attributes in front.

* The undocumented feature of implicit cases goal1, goal2, goal3, etc. 
60617  286 
is marked as legacy, and will be removed eventually. The proof method 
287 
"goals" achieves a similar effect within regular Isar; often it can be 

288

* Nesting of Isar goal structure has been clarified: the context after 
291 
the initial backwards refinement is retained for the whole proof, within 

292 
all its context sections (as indicated via 'next'). This is e.g. 

293 
relevant for 'using', 'including', 'supply':

*** Document preparation *** 
776 

777 
* Document markup commands 'chapter', 'section', 'subsection', 

778 
'subsubsection', 'text', 'txt', 'text_raw' work uniformly in any 

779 
context, even before the initial 'theory' command. Obsolete proof 

780 
commands 'sect', 'subsect', 'subsubsect', 'txt_raw' have been 

781 
discontinued, use 'section', 'subsection', 'subsubsection', 'text_raw' 

782 
instead. The old 'header' command is still retained for some time, but 

783 
should be replaced by 'chapter', 'section' etc. (using "isabelle 

784 
update_header"). Minor INCOMPATIBILITY. 

785 

60010  786 
* Official support for "tt" style variants, via \isatt{...} or 
787 
\begin{isabellett}...\end{isabellett}. The somewhat fragile \verb or 

788 
verbatim environment of LaTeX is no longer used. This allows @{ML} etc. 

789 
as argument to other macros (such as footnotes). 

790 

791 
* Document antiquotation @{verbatim} prints ASCII text literally in "tt" 

792 
style. 

793 

794 
* Discontinued obsolete option "document_graph": session_graph.pdf is 

795 
produced unconditionally for HTML browser_info and PDFLaTeX document. 

796 

59951  797 
* Diagnostic commands and document markup commands within a proof do not 
798 
affect the command tag for output. Thus commands like 'thm' are subject 

799 
to proof document structure, and no longer "stick out" accidentally. 

800 
Commands 'text' and 'txt' merely differ in the LaTeX style, not their 

801 
tags. Potential INCOMPATIBILITY in exotic situations. 

802 

803 
* System option "pretty_margin" is superseded by "thy_output_margin", 

804 
which is also accessible via document antiquotation option "margin". 

805 
Only the margin for document output may be changed, but not the global 

806 
pretty printing: that is 76 for plain console output, and adapted 

807 
dynamically in GUI frontends. Implementations of document 

808 
antiquotations need to observe the margin explicitly according to 

809 
Thy_Output.string_of_margin. Minor INCOMPATIBILITY.

The "sos_cert" functionality is invoked as "sos" with additional

1083 
[approximation] for inequalities of transcendental functions. Uses 

1084 
hardware floating point arithmetic to randomly discover potential 

60011  1085

60010  1101 
* Subtle change of name space policy: undeclared entries are now 
1102 
considered inaccessible, instead of accessible via the fullyqualified 

1103 
internal name. This mainly affects Name_Space.intern (and derivatives), 

1104 
which may produce an unexpected Long_Name.hidden prefix. Note that 

60011  1105 
contemporary applications use the strict Name_Space.check (and 
60010  1106 
derivatives) instead, which is not affected by the change. Potential 
1107 
INCOMPATIBILITY in rare applications of Name_Space.intern. 

59951  1108 

60096  1109 
* Subtle change of error semantics of Toplevel.proof_of: regular user 
1110 
ERROR instead of internal Toplevel.UNDEF. 

1111 

59951  1112 
* Basic combinators map, fold, fold_map, split_list, apply are available 
1113 
as parameterized antiquotations, e.g. @{map 4} for lists of quadruples. 

1114 

1115 
* Renamed "pairself" to "apply2", in accordance to @{apply 2}. 

1116 
INCOMPATIBILITY. 

1117 

1118 
* Former combinators NAMED_CRITICAL and CRITICAL for central critical 

1119 
sections have been discontinued, in favour of the more elementary 

1120 
Multithreading.synchronized and its highlevel derivative 

1121 
Synchronized.var (which is usually sufficient in applications). Subtle 

1122 
INCOMPATIBILITY: synchronized access needs to be atomic and cannot be 

1123 
nested. 

1124 

60010  1125 
* Synchronized.value (ML) is actually synchronized (as in Scala): subtle 
1126 
change of semantics with minimal potential for INCOMPATIBILITY.

* Support for official Standard ML within the Isabelle context. 
1186 
Command 'SML_file' reads and evaluates the given Standard ML file. 

1187 
Toplevel bindings are stored within the theory context; the initial 

1188 
environment is restricted to the Standard ML implementation of 

1189 
Poly/ML, without the addons of Isabelle/ML. Commands 'SML_import' 

1190 
and 'SML_export' allow to exchange toplevel bindings between the two 

1191 
separate environments. See also ~~/src/Tools/SML/Examples.thy for 

1192 
some examples.

1193 

57504  1194 
* Standard tactics and proof methods such as "clarsimp", "auto" and 
1195 
"safe" now preserve equality hypotheses "x = expr" where x is a free 

1196 
variable. Locale assumptions and chained facts containing "x" 

1197 
continue to be useful. The new method "hypsubst_thin" and the 

1198 
configuration option "hypsubst_thin" (within the attribute name space) 

1199 
restore the previous behavior. INCOMPATIBILITY, especially where 

1200 
induction is done after these methods or when the names of free and 

1201 
bound variables clash. As first approximation, old proofs may be 

1202 
repaired by "using [[hypsubst_thin = true]]" in the critical spot. 

1203 

56232  1204 
* More static checking of proof methods, which allows the system to 
1205 
form a closure over the concrete syntax. Method arguments should be 

1206 
processed in the original proof context as far as possible, before 

1207 
operating on the goal state. In any case, the standard discipline for 

1208 
subgoaladdressing needs to be observed: no subgoals or a subgoal 

1209 
number that is out of range produces an empty result sequence, not an 

1210 
exception. Potential INCOMPATIBILITY for nonconformant tactical 

1211 
proof tools. 

1212 

57452  1213 
* Lexical syntax (inner and outer) supports text cartouches with 
1214 
arbitrary nesting, and without escapes of quotes etc. The Prover IDE 

1215 
supports input via ` (backquote). 

1216 

1217 
* The outer syntax categories "text" (for formal comments and document 

1218 
markup commands) and "altstring" (for literal fact references) allow 

1219 
cartouches as well, in addition to the traditional mix of quotations. 

1220 

1221 
* Syntax of document antiquotation @{rail} now uses \<newline> instead 

1222 
of "\\", to avoid the optical illusion of escaped backslash within 

57491  1223 
string token. General renovation of its syntax using text cartouches. 
57452  1224 
Minor INCOMPATIBILITY. 
1225 

1226 
* Discontinued legacy_isub_isup, which was a temporary workaround for 

1227 
Isabelle/ML in Isabelle20131. The prover process no longer accepts 

1228 
old identifier syntax with \<^isub> or \<^isup>. Potential 

1229 
INCOMPATIBILITY. 

1230 

1231 
* Document antiquotation @{url} produces markup for the given URL, 

1232 
which results in an active hyperlink within the text. 

1233 

1234 
* Document antiquotation @{file_unchecked} is like @{file}, but does 

1235 
not check existence within the filesystem.

* Option "jedit_print_mode" (see also "Plugin Options / Isabelle / 
1283 
General") allows to specify additional print modes for the prover 

1284 
process, without requiring oldfashioned commandline invocation of 

1285 
"isabelle jedit m MODE". 

1286

1288 
networking operations instead of jEdit virtual filesystems. 

1289 

57822  1290 
* Empty editors buffers that are no longer required (e.g.\ via theory 
1291 
imports) are automatically removed from the document model. 

1292 

57869  1293 
* Improved monitor panel. 
1294

1296 
more robust treatment of threads and interrupts. 

1297 

56939  1298

1299

* Lowlevel typeclass commands 'classes', 'classrel', 'arities' have 
1310 
been discontinued to avoid the danger of nontrivial axiomatization 

1311 
that is not immediately visible. INCOMPATIBILITY, use regular 

1312 
'instance' command with proof. The required OFCLASS(...) theorem 

1313 
might be postulated via 'axiomatization' beforehand, or the proof 

1314 
finished trivially if the underlying class definition is made vacuous 

1315 
(without any assumptions). See also Isabelle/ML operations 

1316 
Axclass.class_axiomatization, Axclass.classrel_axiomatization, 

1317 
Axclass.arity_axiomatization. 

1318 

56245  1319 
* Basic constants of Pure use more conventional names and are always 
1320 
qualified. Rare INCOMPATIBILITY, but with potentially serious 

1321 
consequences, notably for tools in Isabelle/ML. The following 

1322 
renaming needs to be applied: 

1323 

1324 
== ~> Pure.eq 

1325 
==> ~> Pure.imp 

1326 
all ~> Pure.all 

1327 
TYPE ~> Pure.type 

1328 
dummy_pattern ~> Pure.dummy_pattern 

1329 

1330 
Systematic porting works by using the following theory setup on a 

1331 
*previous* Isabelle version to introduce the new name accesses for the 

1332 
old constants: 

1333 

1334 
setup {* 

1335 
fn thy => thy 

1336 
> Sign.root_path 

1337 
> Sign.const_alias (Binding.qualify true "Pure" @{binding eq}) "==" 

1338 
> Sign.const_alias (Binding.qualify true "Pure" @{binding imp}) "==>" 

1339 
> Sign.const_alias (Binding.qualify true "Pure" @{binding all}) "all" 

1340 
> Sign.restore_naming thy 

1341 
*} 

1342 

1343 
Thus ML antiquotations like @{const_name Pure.eq} may be used already. 

1344 
Later the application is moved to the current Isabelle version, and 

1345 
the auxiliary aliases are deleted.

* Obsolete attribute "standard" has been discontinued (legacy since 
1352 
Isabelle2012). Potential INCOMPATIBILITY, use explicit 'for' context 

1353 
where instantiations with schematic variables are intended (for 

1354 
declaration commands like 'lemmas' or attributes like "of"). The 

1355 
following temporary definition may help to port old applications: 

1356 

1357 
attribute_setup standard = 

1358 
"Scan.succeed (Thm.rule_attribute (K Drule.export_without_context))" 

1359 

55001  1360 
* More thorough check of proof context for goal statements and 
55006  1361 
attributed fact expressions (concerning background theory, declared 
1362 
hyps). Potential INCOMPATIBILITY, tools need to observe standard 

1363 
context discipline. See also Assumption.add_assumes and the more 

1364 
primitive Thm.assume_hyps.
