2 :     correspond to SML/NJ releases.
3 : jhr 1340 --------------------------------------------------------------------------------
4 : jhr 1732
5 : jhr 2547 [2007-05-15]

7 :    
8 : jhr 2449 [2007-04-24]
9 :     Added next function to Fifo and Queue modules.
10 :    
11 : jhr 2337 [2007-02-15]
12 :     Removed vestigial IntInf and INT_INF definitions.
13 :    
14 : jhr 2332 [2007-02-14]
15 :     Changed the representation type of UTF8.wchar from Word32.word to word.
16 :     Also added the UTF8.maxCodePoint value.
17 :    
18 : jhr 2272 [2007-01-30]
19 : jhr 2274 Added the lookup function to the ORD_MAP interface.
20 :    
21 :     [2007-01-30]
22 : jhr 2272 Added the fromList function to the ORD_SET interface. For the red-black
23 :     tree and list based implementations, this operation is linear for ordered
24 :     inputs.
25 :    
26 : jhr 2270 [2007-01-28]
27 :     Added UTF8 signature and structure.
28 :    
29 : jhr 1861 [2005-11-07]
30 :     Internal change: replaced uses of the depreciated Substring.all
31 :     with the Substring.full
32 :    
33 : jhr 1857 [2005-11-05]
34 :     Tweaking of the interval set API. Added iterators on items and
35 :     changed the iterators on intervals to have a "Int" suffix.
36 :     Changed addInterval to addInt, changed list to intervals. Added
37 :     the items function.
38 :    
39 : jhr 1853 [2005-10-31]
40 :     Fixed a bug in IntervalSetFn().intersect.
41 :    
42 : jhr 1840 [2005-10-25]
43 :     Added interval sets to utility library (signatures INTERVAL_DOMAIN
44 :     and INTERVAL_SET, and functor IntervalSetFn).
45 :    
46 : jhr 1833 [2005-08-04]
47 :     Renamed graph-scc.sml to graph-scc-fn.sml.
48 :    
49 : jhr 1830 [2005-07-23]
50 :     Fix PP library to export ANSITermDev, ANSITermPP, PPDescFn, and
51 :     PP_DESC. Also add nbSpace to PP_DESC signature.
52 :    
53 : jhr 1816 [2005-07-12]
54 :     Added ANSITermDev device that uses ANSI terminal display attributes
55 :     and added a ANSITermPP for pretty printing to such a device.
56 :    
57 : jhr 1809 [2005-07-06]
58 : jhr 1810 Added ANSITerm structure, which provides support for ANSI terminal
59 :     display attributes (e.g., red text).
60 :    
61 :     [2005-07-06]
62 : jhr 1809 Refactored the pretty printing library. The declarative way to
63 :     construct pretty-printing descriptions now sits on top of the
64 :     PP_STREAM interface. Also removed "onNewline" function, which
65 :     was not implemented.
66 :    
67 : jhr 1788 [2005-05-05]
68 :     Added singleton function to MONO_PRIORITYQ interface.
69 :    
70 : mblume 1783 [2005-05-04]
71 :     Added the "join" combinator to ParserComb.
72 :    
73 : jhr 1772 [2005-03-21]
74 :     Fixed a bug in GetOpt.getOpt. The argument processing functions
75 :     for ReqArg and OptArg, and the embedding function for ReturnInOrder
76 :     were getting applied to all arguments, even past a "--".
77 :    
78 : jhr 1756 [2005-02-11]
79 :     Added Atom.same and Atom.lexCompare to the Atom structure. Eventually,
80 :     Atom.sameAtom will be removed.
81 :    
82 : jhr 1732 [2004-12-15]
83 :     Change HashString.hashString' to hashSubstring.
84 :    
85 : mblume 1720 [2004-12-09]
86 :     Added two simple statistics modules:
87 :     * RealOrderStats implements selection of arbitrary order
88 :     statistics as well as the median of an array of reals
89 :     in randomized linear time.
90 :     * UnivariateStats implements mean, variance, standard and average
91 :     deviation, skew, kurtosis, and median of a univariate sample
92 :     (i.e., a set of reals).
93 :    
94 : mblume 1718 [2004-11-29]
95 :     Added HashString.hashString' for substrings.
96 :     Hand-inlined CharVector.fold into HashString for efficiency.
97 :     Modified atom.sml so that Atom.atom' first tries to find an
98 :     existing atom before turning its argument into a string. [-blume]
99 :    
100 : mblume 1350 [2003-09-03]
101 :     Minor modifications to random.sml due to changes to some
102 :     Basis interfaces (slices).
103 :     Significant surgery on bit-array.sml to make it compile with
104 :     new signature MONO_ARRAY. This will require further cleanup
105 :     in the future.
106 : monnier 2
107 : mblume 1350 [2003-08-28]
108 :     Made compilation of int-inf* conditional. (The Basis now has
109 :     a spec-conforming implementation of IntInf, so the one here is
110 :     no longer needed.) [-blume]
111 :    
112 : jhr 1340 [2003-07-31]
113 :     Added getDevice function to PP_STREAM signature.
114 :    
115 : mblume 1335 [2003-05-27]
116 :     Avoid poly-eq in Util/parser-comb.sml.
117 :    
118 : mblume 1334 [2003-05-22]
119 :     More cleanup (all in the name of eliminating incomplete matches):
120 :     - in HTML/html-attrs-fn.sml: fill in missing patterns in two
121 :     case expressions
122 :     - in HTML/html-gram: rewrote function groupDefListContents
123 :     to avoid the (unnecessary) incomplete match
124 :     - in PP/devices/html-dev.sml: made the implementation of popStyle
125 :     agree with the comment above it (popStyle on an empty
126 :     stack is supposed to be a nop)
127 : jhr 1340 - in PP/src/pp-stream-fn.sml: function setSize: handle case of
128 :     an empty scanStk
129 : mblume 1334 - in Util/prime-sizes.sml: raise Fail exceptions instead of
130 :     Match exceptions when reaching the end of a list
131 :     (Perhaps this should eventually be rewritten using an on-demand
132 :     prime-number generator that kicks when needed.)
133 : jhr 751
134 : jhr 1333 [2003-05-22]
135 :     Cleanup logic in Scan.scanf function.
136 :    
137 : jhr 1268 [2002-10-03]
138 :     Fixed bug in formating reals with the %g format.
139 :

143 :    
144 : jhr 1206 [2002-05-20]
145 : jhr 1209 Fixed bug in IntInf module: scanning of hex literals was not
146 :     handling "0x" prefixes.
147 :

154 : jhr 1195
155 :     [2002-05-17]
156 : jhr 1194 Added == and != operators to INT_INF interface. These are a
157 :     placeholder until IntInf moves into the SML/NJ compiler.
158 :    
159 : jhr 1193 [2002-05-16]
160 :     Added mergeWith function to ORD_MAP interface.

167 :     combinators to the Util library.
168 :    
169 :     [2002-03-14]

171 :     to this library is likely to change as we get some experience
172 :     with it.
173 :    
174 :     [2002-03-11]
175 :     Added consR1 .. consR5 functions to HashCons library. These
176 :     can be used to hash-cons record types.
177 :    
178 : jhr 1081 [2002-02-21]
179 :     Fixed infinite loop in LeftPriorityQFn.fromList when given a
180 :     singleton list as input (Chris Okasaki provided the fix).
181 : blume 1077
182 :     [2002-02-12]
183 : jhr 1061 Added implementation of priority queues to Util library (using

198 : jhr 816 [2001-05-04]
199 :     Modified GraphSCC module to support a list of roots (Blume).
200 :     The old interface still works, but will be dropped when we move
201 :     to the new Util library.
202 :    
203 :     [2001-04-06]
204 :     Added partition function to ORD_SET interface.

206 :     [2001-04-05]
207 :     Added hasProps function to PropList module.
208 :    
209 :     [2001-03-16]
210 :     Minor bug fix in GetOpt: don't pad the help string, since it causes
211 :     line wraps when one of the help lines is longer than the screen
212 :     width. It was also unneccesary.
213 :    
214 :     [2001-02-23]
215 :     Added inDomain function to the various kinds of hash tables.
216 :    
217 : jhr 785 [2001-02-22]

231 :    
232 : jhr 702 [2000-09-02]
233 :     Added Word versions of hash tables (WordHashTable), finite

235 :    
236 :     [2000-09-02]
237 :     fixed bug in Format module (infinity caused infinite loop).

239 :     [2000-07-19]
240 :     added anchored paths in CM files for NEW_CM.
241 :    
242 : jhr 688 [2000-06-30]

253 :    
254 : jhr 596 [2000-04-05]

256 :     of items in the table was not being recomputed.
257 :    
258 :     [2000-04-04]
259 :     Added modify and modifyi iterators to hash tables.
260 :    
261 :     [2000-03-28]
262 :     Added anchorLink style to HTMLDev structure in PP/devices.
263 :    
264 : monnier 498 [1999-12-03]
265 :     Added IntHashTable structure to Util library; this structure is
266 :     a specialization of hash tables to integer keys.
267 : monnier 2
268 : monnier 498 [1999-12-03]
269 :     Added default cases to avoid "match not exhaustive" warnings.
270 :    
271 :     [1999-12-03]
272 :     Added GraphSCCFn functor to Util library, which implements a
273 :     strongly-connected components algorithm on directed graphs (written
274 :     by Matthias Blume).
275 :    
276 :     [1999-11-10]
277 :     Fixed a benign type error in RegExp/BackEnd/fsm.sml that was exposed by
278 :     the previous change.
279 :    
280 :     [1999-11-7]
281 :     Made the result signatures of ListSetFn and ListMapFn opaque.
282 :    
283 :     [1999-11-1]
284 :     Fixed bug in PP/devices/sources.cm under new CM (missing smlnj-lib.cm).
285 :    
286 : monnier 475 [1999-10-20]
287 :     Fixed bug in RedBlack trees (the linear time construction of
288 :     trees from ordered sequences was producing backwards trees).
289 :    
290 :     [1999-10-18]
291 :     Changed UREF signature so that union, unify, and link operations
292 :     now return a boolean.
293 :    
294 :     [1999-10-18]
295 :     Added peekFn to PropList.newProp return result.
296 :    
297 :     [1999-10-14]
298 :     Added TextIOPP structure to pp-lib.cm (it was not being exported).
299 :    
300 : monnier 469 [1999-09-21]
301 :     Changed the getOpt API. Errors are now reported using a callback
302 :     and both usage and getOpt take records as arguments. Also changed
303 :     the NoArg descriptor to take a function so that imperative argument
304 :     processing can be supported.
305 :    
306 :     [1999-09-20]
307 :     Changed CM files to be compatible with both the old (110.0.x) and

309 :    
310 :     [1999-09-17]
311 :     Added PropList:PROP_LIST structure. This structure implements
312 :     property lists using Stephen Weeks's technique.
313 :    
314 :     [1999-09-17]
315 :     Improved the red-black tree implementations with linear-time union,
316 :     intersection, difference, and filter operations. Also reimplemented
317 :     the delete function in a way that does not require an extra constructor.
318 :    
319 :     [1999-09-09]
320 :     Added Red-Black-Tree implementation of sets and maps. Two new
321 :     functors (RedBlackMapFn and RedBlackSetFn) and four new structures
322 :     (IntRedBlackMap, IntRedBlackSet, AtomIntRedBlackMap, and IntRedBlackSet).
323 :     Also added aliases AtomMap and AtomSet that for the RB implementations.
324 :    
325 :     [1999-09-03]
326 :     Added missing support for WORD and WORD8 format items to Format structure.
327 :     Still need to handle LWORD items!!
328 :    
329 :     [1999-08-17]
330 :     Added DynamicArray:DYNAMIC_ARRAY structure.
331 :    
332 : monnier 411 [1999-07-06]
333 :     Added declarative representation of pretty-printing to PPStreamFn.
334 :     This replaces the PPDescFn and PP_DESC components (which were not
335 :     implemented anyway).
336 :    
337 :     [1999-07-02]
338 :     Moved SockUtil structure into a new INet library. Also split out the
339 :     Unix-specific socket operations into a UnixSockUtil module. (Sockets
340 :     are now supported on Win32).
341 :    
342 :     [1999-06-17]
343 :     Added listKeys function to ORD_MAP API.
344 :    
345 :     [1999-06-14]
346 :     Added Riccardo Pucella's GetOpt structure to Util library.
347 :    
348 :     [1999-06-14]
349 :     Added singleton and inDomain functions to ORD_MAP API.
350 :    
351 :     [1999-06-02]
352 :     Merged in some bug fixes from the compiler's version of the IntInf
353 :     structure.
354 :    
355 : monnier 289 [1999-05-05]
356 :     Fixed a couple of bugs in the PP library having to do with nesting
357 :     absolute and relative indentations.
358 :    
359 :     [1999-04-21]
360 :     Added a way to pass control information to a PP device via the PP
361 :     stream (function control in PP_STREAM).
362 :    
363 :     [1999-04-16]
364 :     Added better style support to the HTML PP device.
365 :    
366 :     [1998-09-04]
367 :     Added isEmpty predicate and first fucntion to ORD_MAP
368 :     signature (and to implementations).
369 :    
370 :     [1998-06-23]
371 :     Fixed a bug in ParserComb.bind (reported by Andrew Kennedy).
372 :    
373 :     --------------------------------------------------------------------------------
374 : monnier 106 [1998-04-15] 110 --> 110.5
375 :     --------------------------
376 :    
377 :     There is now a regular expression library (mostly implemented by Riccardo
378 :     Pucella). The implementation separates front-ends (which specify the
379 :     syntax of REs) from back-ends (which implement the matching algorithms).
380 :     Currently, we support AWK syntax as the only front-end and two different
381 :     back-ends.
382 :    
383 :     Added an implementation of the SML/NJ PP API to the pretty-printer examples.
384 :    
385 :     Fixed a bug in the IntInf structure with scanning strings of the form "1+2".
386 :     Also did some clean-up of the code.
387 :    
388 :    
389 :     --------------------------------------------------------------------------------
390 : monnier 8 [1997-12-07] 109.32 --> 110
391 :     ---------------------------
392 :    
393 : monnier 29 Added the function add' to the ORD_SET signature and the function insert'
394 :     to the ORD_MAP signature. These functions fit the pattern of the fold
395 :     functions. (110 patch 3)
396 :    
397 :     Added the IntInf:INT_INF structure to the Util library. This is a subset
398 :     of the optional IntInf structure defined by the SML'97 basis.
399 :    
400 :     Changed the Rand structure to use words as seeds and results. This also
401 :     fixes bug 1047. (110 patch 3)
402 :    
403 : monnier 8 Added a clear operation to the Queue and various hash table structures.
404 :    
405 :     Changed the ListFormat.formatList to ListFormat.fmt and ListFormat.scanList
406 :     to ListFormat.scan. Added the function ListFormat.listToString.
407 :    
408 :     Updated the HTML library to the final 3.2 specification. This involved adding
409 :     a new BODY element type (with attributes). Also, removed the header/footer
410 :     arguments to the pretty-printer (they were a gross hack).
411 :    
412 :     Added PathUtil structure to Util library. This is a more general version
413 :     of the old UnixPath module.
414 :    
415 :    
416 :     --------------------------------------------------------------------------------
417 :     [1997-10-01] 109.31 --> 109.32
418 :     ------------------------------
419 :    
420 :     Changed the type of the exec instruction in the Reactive library.
421 :    
422 :    
423 :     --------------------------------------------------------------------------------
424 : monnier 2 [1997-09-09] 109.30 --> 109.31
425 :     ------------------------------
426 :    
427 :     Added the Reactive library, which supports reactive scripting. This is a
428 :     first cut, and hasn't been extensively tested.
429 :    
430 :     Changed the names of SockUtil.sock{Recv,Send}* to SockUtil.{recv,send}*
431 :     (since the sock prefix was redundant).
432 :    
433 :     Added some bug fixes to IntListSet that had previously been added to
434 :     the ListSetFn implementation.
435 :    
436 :    
437 :     --------------------------------------------------------------------------------
438 :     [1997-07-17] 109.29 --> 109.30
439 :     ------------------------------
440 :    
441 :     Added a missing case to {ListSetFn,IntListSet}.isSubset.
442 :    
443 :     The bug fix for unionWith was broken. I think I've got it right this
444 :     time.
445 :    
446 :    
447 :     --------------------------------------------------------------------------------
448 :     [1997-07-17] 109.29 --> 109.30
449 :     ------------------------------
450 :    
451 :     Fixed a bug in the binary-tree and splay-tree implementations of the
452 :     unionWith[i] and intersectWith[i] functions. The bug caused the order
453 :     of arguments to the merging function to be wrong in some cases.
454 :    
455 :     Fixed uses of System.Unsafe.
456 :    
457 :     Removed Array2:ARRAY2 from Util library, since the basis now defines these.
458 :    
459 :     Added MonoArrayFn functor for easy creation of monomorphic array structures.
460 :    
461 :     Added Atom.atom' operation for turning substrings into atoms.
462 :    
463 :    
464 :     --------------------------------------------------------------------------------
465 :     [1997-06-13] 109.28 --> 109.29
466 :     ------------------------------
467 :    
468 :     Added collate operation to ORD_MAP signature.
469 :    
470 :     Added compare operation to ORD_SET signature.
471 :    
472 :     Changed the type of and intersectWith[i] in the ORD_MAP signature to be
473 :     more general.
474 :    
475 :     Changed the type of the map function in the ORD_SET signature to return
476 :     a new set (instead of a list).
477 :    
478 :    
479 :     --------------------------------------------------------------------------------
480 :     [1997-05-22] 109.27 --> 109.28
481 :     ------------------------------
482 :    
483 :     Changed various sharing constraints to "where type" definitions to
484 :     compile in SML'97.
485 :    
486 :     Added AtomBinaryMap and AtomBinarySet structures to Util library.
487 :    
488 :    
489 :     --------------------------------------------------------------------------------
490 :     [1997-03-03] 109.25.1 --> 109.25.2
491 :     ----------------------------------
492 :    
493 :     Changed Util/time-limit.sml to reflect new location of callcc/throw.
494 :    
495 :    
496 :     --------------------------------------------------------------------------------
497 :     [1997-02-25] 109.25 --> 109.25.1
498 :     --------------------------------
499 :    
500 :     Added a bunch of new operations to the ordered map modules (BinaryMapFn,
501 :     IntBinaryMap, ListMapFn, IntListFn, and SplayMapFn). The new operations
502 :     are:
503 :     val unionWith : ('a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
504 :     val unionWithi : (Key.ord_key * 'a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
505 :     val intersectWith : ('a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
506 :     val intersectWithi : (Key.ord_key * 'a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
507 :     val filter : ('a -> bool) -> 'a map -> 'a map
508 :     val filteri : (Key.ord_key * 'a -> bool) -> 'a map -> 'a map
509 :     val mapPartial : ('a -> 'b option) -> 'a map -> 'b map
510 :     val mapPartiali : (Key.ord_key * 'a -> 'b option) -> 'a map -> 'b map
511 :    
512 :     Added IOUtil : IO_UTIL structure to the Util library. This provides
513 :     support for dynamically rebinding stdIn and stdOut.
514 :    
515 :     Added KeywordFn functor to the Util library. This provides support for
516 :     implementing scanners, where keyword recognition is done outside the
517 :     basic lexical analysis.
518 :    
519 :     Fixed several bugs in the ListSetFn functor.
520 :    
521 :    
522 :     --------------------------------------------------------------------------------
523 :     [1997-01-10] 109.23 --> 109.24
524 :     ------------------------------
525 :    
526 :     Changed the HASH_TABLE, MONO_HASH_TABLE, MONO_HASH2_TABLE, and ORD_MAP
527 :     interfaces to provide two forms of the listItems function. listItemsi
528 :     returns a list of (key, value) pairs and listItems returns just the values.
529 :     The previous version of listItems was like listItemsi.
530 :    
531 :     Added a missing case for BASEFONT in CheckHTMLFn.check.
532 :    
533 :    
534 :     --------------------------------------------------------------------------------
535 :     [1996-12-07] 109.21.1 --> 109.22
536 :     --------------------------------
537 :    
538 :     Changed the MONO_DYNAMIC_ARRAY signature to make array an eqtype (also changed
539 :     the implementation of DynamicArrayFn).
540 :    
541 :     Fixed a bug in Array2.column
542 :    
543 :    
544 :     --------------------------------------------------------------------------------
545 :     [1996-10-18] 109.19 --> 109.20
546 :     ------------------------------
547 :    
548 :     Added functions for sending/receiving strings over TCP sockets to the
549 :     SockUtil structure.
550 :    
551 :     Fixed a bug with reading on a closed socket in SockUtil.sockRecvVec
552 :    
553 :     Fixed a bug in the implementation of the intersection operation
554 :     in binary sets (BinarySetFn and IntBinarySet).
555 :    
556 :    
557 :     --------------------------------------------------------------------------------
558 :     [1996-10-01] 109.18 --> 109.19
559 :     ------------------------------
560 :    
561 :     Updated the HTML library to the August 21 version of the 3.2 DTD.
562 :    
563 :     Added html-defaults.sml to the HTML Library.
564 :    
565 :     Added Parsing combinators to the Util library.
566 :    
567 :     Added Socket utilities to the Unix library.
