18 :     -------------------
19 :    
20 :     [2011-05-12]
21 : jhr 3596 Modified the implementation of GetOpt.usageInfo so that if the help
22 :     string has embedded newlines, then the extra lines are properly
23 :     indented.
24 :    
25 : jhr 3590 [2011-04-10]
26 :     Changed the interface of JSONStreamParser to support both parsing files

39 :     SML/NJ 110.72
40 :     -------------------
41 :    
42 : jhr 3337 [2009-05-13]
43 :     Added array iterators to DynamicArray module.
44 :    
45 : jhr 3279 [2009-03-15]
46 :     Added support for the interval syntax to the AWK RE syntax parser (this
47 :     syntax was not part of the original version of AWK, but is supported by
48 :     modern variants and the POSIX standard).
49 :    
50 : jhr 3236 [2008-10-03]
51 :     Improved the error messages in the JSON parser.
52 :    
53 : jhr 3194 [2008-06-11]
54 :     Added support for begin marks to Thompson engine.
55 :    
56 :     [2008-05-12]
57 :     Added parsing support to JSON library.
58 :    
59 : jhr 2996 [2008-04-18]
60 :     First commit of JSON Library. Printing works, but parsing still needs
61 :     to be implemented.
62 :    
63 : jhr 2958 [2008-03-18]
64 :     Committed a major overhaul of the RegExp library. There is now a new
65 :     engine that implements Ken Thompson's RE matching algorithm. The result
66 :     type of the RE matches has also been simplified by removing an unecessary
67 :     option type.
68 :     NOTE: the new RE engine is not complete in that it does not yet support
69 :     begin/end marks.
70 :    
71 : blume 2918 [2007-12-13]
72 : blume 2919 Also added list' and listg' which are parameterized over the delimiter-
73 :     and separator strings used for formatting lists. (The default for "list" and
74 : jhr 2935 "listg" is the usual "[" ", " "]".)
75 : blume 2919
76 :     [2007-12-13]
77 : blume 2918 Added "elem" function as an inverse to "glue" to FormatComb module.
78 :     This makes writing extensions possible. Also added "list" and "option"
79 :     combinators for formatting list- and option types.
80 :    
81 : jhr 2832 [2007-11-02]
82 : jhr 2830 A collection of bug fixes for machine.sml in the Reactive library.
83 :     (Thanks to Timothy Bourke)
84 :    
85 : jhr 2547 [2007-05-15]
86 :     Made the UnixPath.path_list type concrete (= string list).
87 :    
88 : jhr 2449 [2007-04-24]
89 :     Added next function to Fifo and Queue modules.
90 :    
91 : jhr 2337 [2007-02-15]
92 :     Removed vestigial IntInf and INT_INF definitions.
93 :    
94 : jhr 2332 [2007-02-14]
95 :     Changed the representation type of UTF8.wchar from Word32.word to word.
96 :     Also added the UTF8.maxCodePoint value.
97 :    
98 : jhr 2272 [2007-01-30]
99 : jhr 2274 Added the lookup function to the ORD_MAP interface.
100 :    
101 :     [2007-01-30]
102 : jhr 2272 Added the fromList function to the ORD_SET interface. For the red-black
103 :     tree and list based implementations, this operation is linear for ordered
104 :     inputs.
105 :    
106 : jhr 2270 [2007-01-28]
107 :     Added UTF8 signature and structure.
108 :    
109 : jhr 1861 [2005-11-07]
110 :     Internal change: replaced uses of the depreciated Substring.all
111 :     with the Substring.full
112 :    
113 : jhr 1857 [2005-11-05]
114 :     Tweaking of the interval set API. Added iterators on items and
115 :     changed the iterators on intervals to have a "Int" suffix.
116 :     Changed addInterval to addInt, changed list to intervals. Added
117 :     the items function.
118 :    
119 : jhr 1853 [2005-10-31]
120 :     Fixed a bug in IntervalSetFn().intersect.
121 :    
122 : jhr 1840 [2005-10-25]
123 :     Added interval sets to utility library (signatures INTERVAL_DOMAIN
124 :     and INTERVAL_SET, and functor IntervalSetFn).
125 :    
126 : jhr 1833 [2005-08-04]
127 :     Renamed graph-scc.sml to graph-scc-fn.sml.
128 :    
129 : jhr 1830 [2005-07-23]
130 :     Fix PP library to export ANSITermDev, ANSITermPP, PPDescFn, and
131 :     PP_DESC. Also add nbSpace to PP_DESC signature.
132 :    
133 : jhr 1816 [2005-07-12]
134 :     Added ANSITermDev device that uses ANSI terminal display attributes
135 :     and added a ANSITermPP for pretty printing to such a device.
136 :    
137 : jhr 1809 [2005-07-06]
138 : jhr 1810 Added ANSITerm structure, which provides support for ANSI terminal
139 :     display attributes (e.g., red text).
140 :    
141 :     [2005-07-06]
142 : jhr 1809 Refactored the pretty printing library. The declarative way to
143 :     construct pretty-printing descriptions now sits on top of the
144 :     PP_STREAM interface. Also removed "onNewline" function, which
145 :     was not implemented.
146 :    
147 : jhr 1788 [2005-05-05]
148 :     Added singleton function to MONO_PRIORITYQ interface.
149 :    
150 : mblume 1783 [2005-05-04]
151 :     Added the "join" combinator to ParserComb.
152 :    
153 : jhr 1772 [2005-03-21]
154 :     Fixed a bug in GetOpt.getOpt. The argument processing functions
155 :     for ReqArg and OptArg, and the embedding function for ReturnInOrder
156 :     were getting applied to all arguments, even past a "--".
157 :    
158 : jhr 1756 [2005-02-11]
159 :     Added Atom.same and Atom.lexCompare to the Atom structure. Eventually,
160 :     Atom.sameAtom will be removed.
161 :    
162 : jhr 1732 [2004-12-15]
163 :     Change HashString.hashString' to hashSubstring.
164 :    
165 : mblume 1720 [2004-12-09]
166 :     Added two simple statistics modules:
167 :     * RealOrderStats implements selection of arbitrary order
168 :     statistics as well as the median of an array of reals
169 :     in randomized linear time.
170 :     * UnivariateStats implements mean, variance, standard and average
171 :     deviation, skew, kurtosis, and median of a univariate sample
172 :     (i.e., a set of reals).
173 :    
174 : mblume 1718 [2004-11-29]
175 :     Added HashString.hashString' for substrings.
176 :     Hand-inlined CharVector.fold into HashString for efficiency.
177 :     Modified atom.sml so that Atom.atom' first tries to find an
178 :     existing atom before turning its argument into a string. [-blume]
179 :    
180 : mblume 1350 [2003-09-03]
181 :     Minor modifications to random.sml due to changes to some
182 :     Basis interfaces (slices).
183 :     Significant surgery on bit-array.sml to make it compile with
184 :     new signature MONO_ARRAY. This will require further cleanup
185 :     in the future.
186 : monnier 2
187 : mblume 1350 [2003-08-28]
188 :     Made compilation of int-inf* conditional. (The Basis now has
189 :     a spec-conforming implementation of IntInf, so the one here is
190 :     no longer needed.) [-blume]
191 :    
192 : jhr 1340 [2003-07-31]
193 :     Added getDevice function to PP_STREAM signature.
194 :    
195 : mblume 1335 [2003-05-27]
196 :     Avoid poly-eq in Util/parser-comb.sml.
197 :    
198 : mblume 1334 [2003-05-22]
199 :     More cleanup (all in the name of eliminating incomplete matches):
200 :     - in HTML/html-attrs-fn.sml: fill in missing patterns in two
201 :     case expressions
202 :     - in HTML/html-gram: rewrote function groupDefListContents
203 :     to avoid the (unnecessary) incomplete match
204 :     - in PP/devices/html-dev.sml: made the implementation of popStyle
205 :     agree with the comment above it (popStyle on an empty
206 :     stack is supposed to be a nop)
207 : jhr 1340 - in PP/src/pp-stream-fn.sml: function setSize: handle case of
208 :     an empty scanStk
209 : mblume 1334 - in Util/prime-sizes.sml: raise Fail exceptions instead of
210 :     Match exceptions when reaching the end of a list
211 :     (Perhaps this should eventually be rewritten using an on-demand
212 :     prime-number generator that kicks when needed.)
213 : jhr 751
214 : jhr 1333 [2003-05-22]
215 :     Cleanup logic in Scan.scanf function.
216 :    
217 : jhr 1268 [2002-10-03]

223 :    
224 : jhr 1206 [2002-05-20]
225 : jhr 1209 Fixed bug in IntInf module: scanning of hex literals was not
226 :     handling "0x" prefixes.
227 :    
228 :     [2002-05-20]
229 : jhr 1206 Added ControlUtil module and stringControls function.
230 :    
231 : jhr 1194 [2002-05-17]
232 : jhr 1199 Added tyName field to ValueSyntax exception in Controls module
233 :     and path field to registry tree in ControlRegistry module.
234 : jhr 1195
235 :     [2002-05-17]
236 : jhr 1194 Added == and != operators to INT_INF interface. These are a
237 :     placeholder until IntInf moves into the SML/NJ compiler.
238 :    
239 : jhr 1193 [2002-05-16]
240 :     Added mergeWith function to ORD_MAP interface.
241 :

247 :     combinators to the Util library.
248 :    
249 :     [2002-03-14]
250 :     Merged in Matthias Blume's Controls library. Warning: the API
251 :     to this library is likely to change as we get some experience
252 :     with it.
253 :    
254 :     [2002-03-11]
255 :     Added consR1 .. consR5 functions to HashCons library. These
256 :     can be used to hash-cons record types.
257 :    
258 : jhr 1081 [2002-02-21]
259 :     Fixed infinite loop in LeftPriorityQFn.fromList when given a
260 :     singleton list as input (Chris Okasaki provided the fix).
261 : blume 1077
262 :     [2002-02-12]
263 : jhr 1061 Added implementation of priority queues to Util library (using
264 :     Okasaki's leftist-tree implementation).

266 : jhr 967 [2001-10-19]
267 :     Added new HashCons library.
268 :    
269 :     [2001-10-19]

280 :     The old interface still works, but will be dropped when we move
281 :     to the new Util library.
282 :    
283 :     [2001-04-06]
284 :     Added partition function to ORD_SET interface.
285 :    
286 :     [2001-04-05]
287 :     Added hasProps function to PropList module.
288 :    
289 :     [2001-03-16]
290 :     Minor bug fix in GetOpt: don't pad the help string, since it causes
291 :     line wraps when one of the help lines is longer than the screen
292 :     width. It was also unneccesary.
293 :    
294 :     [2001-02-23]
295 :     Added inDomain function to the various kinds of hash tables.
296 :    
297 : jhr 785 [2001-02-22]

369 :    
370 :     [1999-10-18]
371 :     Changed UREF signature so that union, unify, and link operations
372 :     now return a boolean.
373 :    
374 :     [1999-10-18]
375 :     Added peekFn to PropList.newProp return result.
376 :

379 :    
380 : monnier 469 [1999-09-21]
381 :     Changed the getOpt API. Errors are now reported using a callback
382 :     and both usage and getOpt take records as arguments. Also changed
383 :     the NoArg descriptor to take a function so that imperative argument
384 :     processing can be supported.
385 :    
386 :     [1999-09-20]
387 :     Changed CM files to be compatible with both the old (110.0.x) and

389 :    
390 :     [1999-09-17]
391 :     Added PropList:PROP_LIST structure. This structure implements

393 :    
394 :     [1999-09-17]
395 :     Improved the red-black tree implementations with linear-time union,
396 :     intersection, difference, and filter operations. Also reimplemented
397 :     the delete function in a way that does not require an extra constructor.
398 :    
399 :     [1999-09-09]
400 :     Added Red-Black-Tree implementation of sets and maps. Two new
401 :     functors (RedBlackMapFn and RedBlackSetFn) and four new structures
402 :     (IntRedBlackMap, IntRedBlackSet, AtomIntRedBlackMap, and IntRedBlackSet).
403 :     Also added aliases AtomMap and AtomSet that for the RB implementations.
404 :    
405 :     [1999-09-03]
406 :     Added missing support for WORD and WORD8 format items to Format structure.
407 :     Still need to handle LWORD items!!
408 :    
409 :     [1999-08-17]
410 :     Added DynamicArray:DYNAMIC_ARRAY structure.
411 :    
412 : monnier 411 [1999-07-06]
413 :     Added declarative representation of pretty-printing to PPStreamFn.
414 :     This replaces the PPDescFn and PP_DESC components (which were not
415 :     implemented anyway).
416 :    
417 :     [1999-07-02]
418 :     Moved SockUtil structure into a new INet library. Also split out the
419 :     Unix-specific socket operations into a UnixSockUtil module. (Sockets
420 :     are now supported on Win32).
421 :    
422 :     [1999-06-17]
423 :     Added listKeys function to ORD_MAP API.
424 :    
425 :     [1999-06-14]

433 :     structure.
434 :    
435 : monnier 289 [1999-05-05]
436 :     Fixed a couple of bugs in the PP library having to do with nesting
437 :     absolute and relative indentations.
438 :    
439 :     [1999-04-21]
440 :     Added a way to pass control information to a PP device via the PP
441 :     stream (function control in PP_STREAM).
442 :    
443 :     [1999-04-16]
444 :     Added better style support to the HTML PP device.
445 :    
446 :     [1998-09-04]
447 :     Added isEmpty predicate and first fucntion to ORD_MAP
448 :     signature (and to implementations).
449 :    
450 :     [1998-06-23]
451 :     Fixed a bug in ParserComb.bind (reported by Andrew Kennedy).
452 :    
453 :     --------------------------------------------------------------------------------
454 : monnier 106 [1998-04-15] 110 --> 110.5
455 :     --------------------------
456 :    
457 :     There is now a regular expression library (mostly implemented by Riccardo
458 :     Pucella). The implementation separates front-ends (which specify the
459 :     syntax of REs) from back-ends (which implement the matching algorithms).
460 :     Currently, we support AWK syntax as the only front-end and two different
461 :     back-ends.
462 :    
463 :     Added an implementation of the SML/NJ PP API to the pretty-printer examples.
464 :    
465 :     Fixed a bug in the IntInf structure with scanning strings of the form "1+2".
466 :     Also did some clean-up of the code.
467 :    
468 :    
469 :     --------------------------------------------------------------------------------
470 : monnier 8 [1997-12-07] 109.32 --> 110
471 :     ---------------------------
472 :    
473 : monnier 29 Added the function add' to the ORD_SET signature and the function insert'
474 :     to the ORD_MAP signature. These functions fit the pattern of the fold
475 :     functions. (110 patch 3)
476 :    
477 :     Added the IntInf:INT_INF structure to the Util library. This is a subset
478 :     of the optional IntInf structure defined by the SML'97 basis.
479 :    
480 :     Changed the Rand structure to use words as seeds and results. This also
481 :     fixes bug 1047. (110 patch 3)
482 :    
483 : monnier 8 Added a clear operation to the Queue and various hash table structures.
484 :    
485 :     Changed the ListFormat.formatList to ListFormat.fmt and ListFormat.scanList
486 :     to ListFormat.scan. Added the function ListFormat.listToString.
487 :    
488 :     Updated the HTML library to the final 3.2 specification. This involved adding
489 :     a new BODY element type (with attributes). Also, removed the header/footer
490 :     arguments to the pretty-printer (they were a gross hack).
491 :    
492 :     Added PathUtil structure to Util library. This is a more general version
493 :     of the old UnixPath module.
494 :    
495 :    
496 :     --------------------------------------------------------------------------------
497 :     [1997-10-01] 109.31 --> 109.32
498 :     ------------------------------
499 :    
500 :     Changed the type of the exec instruction in the Reactive library.
501 :    
502 :    
503 :     --------------------------------------------------------------------------------
504 : monnier 2 [1997-09-09] 109.30 --> 109.31
505 :     ------------------------------
506 :    
507 :     Added the Reactive library, which supports reactive scripting. This is a
508 :     first cut, and hasn't been extensively tested.
509 :    
510 :     Changed the names of SockUtil.sock{Recv,Send}* to SockUtil.{recv,send}*
511 :     (since the sock prefix was redundant).
512 :    
513 :     Added some bug fixes to IntListSet that had previously been added to
514 :     the ListSetFn implementation.
515 :    
516 :    
517 :     --------------------------------------------------------------------------------
518 :     [1997-07-17] 109.29 --> 109.30
519 :     ------------------------------
520 :    
521 :     Added a missing case to {ListSetFn,IntListSet}.isSubset.
522 :    
523 :     The bug fix for unionWith was broken. I think I've got it right this
524 :     time.
525 :    
526 :    
527 :     --------------------------------------------------------------------------------
528 :     [1997-07-17] 109.29 --> 109.30
529 :     ------------------------------
530 :    
531 :     Fixed a bug in the binary-tree and splay-tree implementations of the
532 :     unionWith[i] and intersectWith[i] functions. The bug caused the order
533 :     of arguments to the merging function to be wrong in some cases.
534 :    
535 :     Fixed uses of System.Unsafe.
536 :    
537 :     Removed Array2:ARRAY2 from Util library, since the basis now defines these.
538 :    
539 :     Added MonoArrayFn functor for easy creation of monomorphic array structures.
540 :    
541 :     Added Atom.atom' operation for turning substrings into atoms.
542 :    
543 :    
544 :     --------------------------------------------------------------------------------
545 :     [1997-06-13] 109.28 --> 109.29
546 :     ------------------------------
547 :    
548 :     Added collate operation to ORD_MAP signature.
549 :    
550 :     Added compare operation to ORD_SET signature.
551 :    
552 :     Changed the type of and intersectWith[i] in the ORD_MAP signature to be
553 :     more general.
554 :    
555 :     Changed the type of the map function in the ORD_SET signature to return
556 :     a new set (instead of a list).
557 :    
558 :    
559 :     --------------------------------------------------------------------------------
560 :     [1997-05-22] 109.27 --> 109.28
561 :     ------------------------------
562 :    
563 :     Changed various sharing constraints to "where type" definitions to
564 :     compile in SML'97.
565 :    
566 :     Added AtomBinaryMap and AtomBinarySet structures to Util library.
567 :    
568 :    
569 :     --------------------------------------------------------------------------------
570 :     [1997-03-03] 109.25.1 --> 109.25.2
571 :     ----------------------------------
572 :    
573 :     Changed Util/time-limit.sml to reflect new location of callcc/throw.
574 :    
575 :    
576 :     --------------------------------------------------------------------------------
577 :     [1997-02-25] 109.25 --> 109.25.1
578 :     --------------------------------
579 :    
580 :     Added a bunch of new operations to the ordered map modules (BinaryMapFn,
581 :     IntBinaryMap, ListMapFn, IntListFn, and SplayMapFn). The new operations
582 :     are:
583 :     val unionWith : ('a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
584 :     val unionWithi : (Key.ord_key * 'a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
585 :     val intersectWith : ('a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
586 :     val intersectWithi : (Key.ord_key * 'a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
587 :     val filter : ('a -> bool) -> 'a map -> 'a map
588 :     val filteri : (Key.ord_key * 'a -> bool) -> 'a map -> 'a map
589 :     val mapPartial : ('a -> 'b option) -> 'a map -> 'b map
590 :     val mapPartiali : (Key.ord_key * 'a -> 'b option) -> 'a map -> 'b map
591 :    
592 :     Added IOUtil : IO_UTIL structure to the Util library. This provides
593 :     support for dynamically rebinding stdIn and stdOut.
594 :    
595 :     Added KeywordFn functor to the Util library. This provides support for
596 :     implementing scanners, where keyword recognition is done outside the
597 :     basic lexical analysis.
598 :    
599 :     Fixed several bugs in the ListSetFn functor.
600 :    
601 :    
602 :     --------------------------------------------------------------------------------
603 :     [1997-01-10] 109.23 --> 109.24
604 :     ------------------------------
605 :    
606 :     Changed the HASH_TABLE, MONO_HASH_TABLE, MONO_HASH2_TABLE, and ORD_MAP
607 :     interfaces to provide two forms of the listItems function. listItemsi
608 :     returns a list of (key, value) pairs and listItems returns just the values.
609 :     The previous version of listItems was like listItemsi.
610 :    
611 :     Added a missing case for BASEFONT in CheckHTMLFn.check.
612 :    
613 :    
614 :     --------------------------------------------------------------------------------
615 :     [1996-12-07] 109.21.1 --> 109.22
616 :     --------------------------------
617 :    
618 :     Changed the MONO_DYNAMIC_ARRAY signature to make array an eqtype (also changed
619 :     the implementation of DynamicArrayFn).
620 :    
621 :     Fixed a bug in Array2.column
622 :    
623 :    
624 :     --------------------------------------------------------------------------------
625 :     [1996-10-18] 109.19 --> 109.20
626 :     ------------------------------
627 :    
628 :     Added functions for sending/receiving strings over TCP sockets to the
629 :     SockUtil structure.
630 :    
631 :     Fixed a bug with reading on a closed socket in SockUtil.sockRecvVec
632 :    
633 :     Fixed a bug in the implementation of the intersection operation
634 :     in binary sets (BinarySetFn and IntBinarySet).
635 :    
636 :    
637 :     --------------------------------------------------------------------------------
638 :     [1996-10-01] 109.18 --> 109.19
639 :     ------------------------------
640 :    
641 :     Updated the HTML library to the August 21 version of the 3.2 DTD.
642 :    
643 :     Added html-defaults.sml to the HTML Library.
644 :    
645 :     Added Parsing combinators to the Util library.
646 :    
647 :     Added Socket utilities to the Unix library.
