1 : monnier 2 This is a list of changes to the SML/NJ Library; the version numbers
2 :     correspond to SML/NJ releases.
3 : jhr 1340 --------------------------------------------------------------------------------
4 : jhr 1732
5 : jhr 2332 [2007-02-14]
6 :     Changed the representation type of UTF8.wchar from Word32.word to word.
7 :     Also added the UTF8.maxCodePoint value.
8 :    
9 : jhr 2272 [2007-01-30]
10 : jhr 2274 Added the lookup function to the ORD_MAP interface.
11 :    
12 :     [2007-01-30]
13 : jhr 2272 Added the fromList function to the ORD_SET interface. For the red-black
14 :     tree and list based implementations, this operation is linear for ordered
15 :     inputs.
16 :    
17 : jhr 2270 [2007-01-28]
18 :     Added UTF8 signature and structure.
19 :    
20 : jhr 1861 [2005-11-07]
21 :     Internal change: replaced uses of the depreciated Substring.all
22 :     with the Substring.full
23 :    
24 : jhr 1857 [2005-11-05]
25 :     Tweaking of the interval set API. Added iterators on items and
26 :     changed the iterators on intervals to have a "Int" suffix.
27 :     Changed addInterval to addInt, changed list to intervals. Added
28 :     the items function.
29 :    
30 : jhr 1853 [2005-10-31]
31 :     Fixed a bug in IntervalSetFn().intersect.
32 :    
33 : jhr 1840 [2005-10-25]
34 :     Added interval sets to utility library (signatures INTERVAL_DOMAIN
35 :     and INTERVAL_SET, and functor IntervalSetFn).
36 :    
37 : jhr 1833 [2005-08-04]
38 :     Renamed graph-scc.sml to graph-scc-fn.sml.
39 :    
40 : jhr 1830 [2005-07-23]
41 :     Fix PP library to export ANSITermDev, ANSITermPP, PPDescFn, and
42 :     PP_DESC. Also add nbSpace to PP_DESC signature.
43 :    
44 : jhr 1816 [2005-07-12]
45 :     Added ANSITermDev device that uses ANSI terminal display attributes
46 :     and added a ANSITermPP for pretty printing to such a device.
47 :    
48 : jhr 1809 [2005-07-06]
49 : jhr 1810 Added ANSITerm structure, which provides support for ANSI terminal
50 :     display attributes (e.g., red text).
51 :    
52 :     [2005-07-06]
53 : jhr 1809 Refactored the pretty printing library. The declarative way to
54 :     construct pretty-printing descriptions now sits on top of the
55 :     PP_STREAM interface. Also removed "onNewline" function, which
56 :     was not implemented.
57 :    
58 : jhr 1788 [2005-05-05]
59 :     Added singleton function to MONO_PRIORITYQ interface.
60 :    
61 : mblume 1783 [2005-05-04]
62 :     Added the "join" combinator to ParserComb.
63 :    
64 : jhr 1772 [2005-03-21]
65 :     Fixed a bug in GetOpt.getOpt. The argument processing functions
66 :     for ReqArg and OptArg, and the embedding function for ReturnInOrder
67 :     were getting applied to all arguments, even past a "--".
68 :    
69 : jhr 1756 [2005-02-11]
70 :     Added Atom.same and Atom.lexCompare to the Atom structure. Eventually,
71 :     Atom.sameAtom will be removed.
72 :    
73 : jhr 1732 [2004-12-15]
74 :     Change HashString.hashString' to hashSubstring.
75 :    
76 : mblume 1720 [2004-12-09]
77 :     Added two simple statistics modules:
78 :     * RealOrderStats implements selection of arbitrary order
79 :     statistics as well as the median of an array of reals
80 :     in randomized linear time.
81 :     * UnivariateStats implements mean, variance, standard and average
82 :     deviation, skew, kurtosis, and median of a univariate sample
83 :     (i.e., a set of reals).
84 :    
85 : mblume 1718 [2004-11-29]
86 :     Added HashString.hashString' for substrings.
87 :     Hand-inlined CharVector.fold into HashString for efficiency.
88 :     Modified atom.sml so that Atom.atom' first tries to find an
89 :     existing atom before turning its argument into a string. [-blume]
90 :    
91 : mblume 1350 [2003-09-03]
92 :     Minor modifications to random.sml due to changes to some
93 :     Basis interfaces (slices).
94 :     Significant surgery on bit-array.sml to make it compile with
95 :     new signature MONO_ARRAY. This will require further cleanup
96 :     in the future.
97 : monnier 2
98 : mblume 1350 [2003-08-28]
99 :     Made compilation of int-inf* conditional. (The Basis now has
100 :     a spec-conforming implementation of IntInf, so the one here is
101 :     no longer needed.) [-blume]
102 :    
103 : jhr 1340 [2003-07-31]
104 :     Added getDevice function to PP_STREAM signature.
105 :    
106 : mblume 1335 [2003-05-27]
107 :     Avoid poly-eq in Util/parser-comb.sml.
108 :    
109 : mblume 1334 [2003-05-22]
110 :     More cleanup (all in the name of eliminating incomplete matches):
111 :     - in HTML/html-attrs-fn.sml: fill in missing patterns in two
112 :     case expressions
113 :     - in HTML/html-gram: rewrote function groupDefListContents
114 :     to avoid the (unnecessary) incomplete match
115 :     - in PP/devices/html-dev.sml: made the implementation of popStyle
116 :     agree with the comment above it (popStyle on an empty
117 :     stack is supposed to be a nop)
118 : jhr 1340 - in PP/src/pp-stream-fn.sml: function setSize: handle case of
119 :     an empty scanStk
120 : mblume 1334 - in Util/prime-sizes.sml: raise Fail exceptions instead of
121 :     Match exceptions when reaching the end of a list
122 :     (Perhaps this should eventually be rewritten using an on-demand
123 :     prime-number generator that kicks when needed.)
124 : jhr 751
125 : jhr 1333 [2003-05-22]
126 :     Cleanup logic in Scan.scanf function.
127 :    
128 : jhr 1268 [2002-10-03]
129 :     Fixed bug in formating reals with the %g format.
130 :    
131 : jhr 1248 [2002-06-18]

133 :     Sami Nopanen.
134 :    
135 : jhr 1206 [2002-05-20]
136 : jhr 1209 Fixed bug in IntInf module: scanning of hex literals was not
137 :     handling "0x" prefixes.
138 :    
139 :     [2002-05-20]

145 : jhr 1195
146 :     [2002-05-17]
147 : jhr 1194 Added == and != operators to INT_INF interface. These are a
148 :     placeholder until IntInf moves into the SML/NJ compiler.
149 :    
150 : jhr 1193 [2002-05-16]

158 :     combinators to the Util library.
159 :    
160 :     [2002-03-14]

162 :     to this library is likely to change as we get some experience
163 :     with it.
164 :    
165 :     [2002-03-11]
166 :     Added consR1 .. consR5 functions to HashCons library. These
167 :     can be used to hash-cons record types.
168 :    
169 : jhr 1081 [2002-02-21]
170 :     Fixed infinite loop in LeftPriorityQFn.fromList when given a
171 :     singleton list as input (Chris Okasaki provided the fix).
172 : blume 1077
173 :     [2002-02-12]
174 : jhr 1061 Added implementation of priority queues to Util library (using
175 :     Okasaki's leftist-tree implementation).

177 : jhr 967 [2001-10-19]
178 :     Added new HashCons library.
179 :    
180 :     [2001-10-19]

188 :    
189 : jhr 816 [2001-05-04]
190 :     Modified GraphSCC module to support a list of roots (Blume).
191 :     The old interface still works, but will be dropped when we move
192 :     to the new Util library.
193 :    
194 :     [2001-04-06]
195 :     Added partition function to ORD_SET interface.
196 :    
197 :     [2001-04-05]
198 :     Added hasProps function to PropList module.
199 :    
200 :     [2001-03-16]
201 :     Minor bug fix in GetOpt: don't pad the help string, since it causes
202 :     line wraps when one of the help lines is longer than the screen
203 :     width. It was also unneccesary.
204 :    
205 :     [2001-02-23]
206 :     Added inDomain function to the various kinds of hash tables.
207 :    
208 : jhr 785 [2001-02-22]

222 :    
223 : jhr 702 [2000-09-02]
224 :     Added Word versions of hash tables (WordHashTable), finite

226 :    
227 :     [2000-09-02]
228 :     fixed bug in Format module (infinity caused infinite loop).
229 :    
230 :     [2000-07-19]
231 :     added anchored paths in CM files for NEW_CM.
232 :    
233 : jhr 688 [2000-06-30]

244 :    
245 : jhr 596 [2000-04-05]

252 :     [2000-03-28]
253 :     Added anchorLink style to HTMLDev structure in PP/devices.
254 :    
255 : monnier 498 [1999-12-03]
256 :     Added IntHashTable structure to Util library; this structure is
257 :     a specialization of hash tables to integer keys.
258 : monnier 2
259 : monnier 498 [1999-12-03]
260 :     Added default cases to avoid "match not exhaustive" warnings.
261 :    
262 :     [1999-12-03]
263 :     Added GraphSCCFn functor to Util library, which implements a
264 :     strongly-connected components algorithm on directed graphs (written
265 :     by Matthias Blume).
266 :    
267 :     [1999-11-10]
268 :     Fixed a benign type error in RegExp/BackEnd/fsm.sml that was exposed by
269 :     the previous change.
270 :    
271 :     [1999-11-7]
272 :     Made the result signatures of ListSetFn and ListMapFn opaque.
273 :    
274 :     [1999-11-1]
275 :     Fixed bug in PP/devices/sources.cm under new CM (missing smlnj-lib.cm).
276 :    
277 : monnier 475 [1999-10-20]
278 :     Fixed bug in RedBlack trees (the linear time construction of
279 :     trees from ordered sequences was producing backwards trees).
280 :    
281 :     [1999-10-18]
282 :     Changed UREF signature so that union, unify, and link operations
283 :     now return a boolean.
284 :    
285 :     [1999-10-18]
286 :     Added peekFn to PropList.newProp return result.
287 :    
288 :     [1999-10-14]
289 :     Added TextIOPP structure to pp-lib.cm (it was not being exported).
290 :    
291 : monnier 469 [1999-09-21]
292 :     Changed the getOpt API. Errors are now reported using a callback
293 :     and both usage and getOpt take records as arguments. Also changed
294 :     the NoArg descriptor to take a function so that imperative argument
295 :     processing can be supported.
296 :    
297 :     [1999-09-20]
298 :     Changed CM files to be compatible with both the old (110.0.x) and

300 :    
301 :     [1999-09-17]
302 :     Added PropList:PROP_LIST structure. This structure implements
303 :     property lists using Stephen Weeks's technique.
304 :    
305 :     [1999-09-17]
306 :     Improved the red-black tree implementations with linear-time union,
307 :     intersection, difference, and filter operations. Also reimplemented
308 :     the delete function in a way that does not require an extra constructor.
309 :    
310 :     [1999-09-09]
311 :     Added Red-Black-Tree implementation of sets and maps. Two new
312 :     functors (RedBlackMapFn and RedBlackSetFn) and four new structures
313 :     (IntRedBlackMap, IntRedBlackSet, AtomIntRedBlackMap, and IntRedBlackSet).
314 :     Also added aliases AtomMap and AtomSet that for the RB implementations.
315 :    
316 :     [1999-09-03]
317 :     Added missing support for WORD and WORD8 format items to Format structure.
318 :     Still need to handle LWORD items!!
319 :    
320 :     [1999-08-17]
321 :     Added DynamicArray:DYNAMIC_ARRAY structure.
322 :    
323 : monnier 411 [1999-07-06]
324 :     Added declarative representation of pretty-printing to PPStreamFn.
325 :     This replaces the PPDescFn and PP_DESC components (which were not
326 :     implemented anyway).
327 :    
328 :     [1999-07-02]
329 :     Moved SockUtil structure into a new INet library. Also split out the
330 :     Unix-specific socket operations into a UnixSockUtil module. (Sockets
331 :     are now supported on Win32).
332 :    
333 :     [1999-06-17]
334 :     Added listKeys function to ORD_MAP API.
335 :    
336 :     [1999-06-14]
337 :     Added Riccardo Pucella's GetOpt structure to Util library.
338 :    
339 :     [1999-06-14]
340 :     Added singleton and inDomain functions to ORD_MAP API.
341 :    
342 :     [1999-06-02]
343 :     Merged in some bug fixes from the compiler's version of the IntInf
344 :     structure.
345 :    
346 : monnier 289 [1999-05-05]
347 :     Fixed a couple of bugs in the PP library having to do with nesting
348 :     absolute and relative indentations.
349 :    
350 :     [1999-04-21]
351 :     Added a way to pass control information to a PP device via the PP
352 :     stream (function control in PP_STREAM).
353 :    
354 :     [1999-04-16]
355 :     Added better style support to the HTML PP device.
356 :    
357 :     [1998-09-04]
358 :     Added isEmpty predicate and first fucntion to ORD_MAP
359 :     signature (and to implementations).
360 :    
361 :     [1998-06-23]
362 :     Fixed a bug in ParserComb.bind (reported by Andrew Kennedy).
363 :    
364 :     --------------------------------------------------------------------------------
365 : monnier 106 [1998-04-15] 110 --> 110.5
366 :     --------------------------
367 :    
368 :     There is now a regular expression library (mostly implemented by Riccardo
369 :     Pucella). The implementation separates front-ends (which specify the
370 :     syntax of REs) from back-ends (which implement the matching algorithms).
371 :     Currently, we support AWK syntax as the only front-end and two different
372 :     back-ends.
373 :    
374 :     Added an implementation of the SML/NJ PP API to the pretty-printer examples.
375 :    
376 :     Fixed a bug in the IntInf structure with scanning strings of the form "1+2".
377 :     Also did some clean-up of the code.
378 :    
379 :    
380 :     --------------------------------------------------------------------------------
381 : monnier 8 [1997-12-07] 109.32 --> 110
382 :     ---------------------------
383 :    
384 : monnier 29 Added the function add' to the ORD_SET signature and the function insert'
385 :     to the ORD_MAP signature. These functions fit the pattern of the fold
386 :     functions. (110 patch 3)
387 :    
388 :     Added the IntInf:INT_INF structure to the Util library. This is a subset
389 :     of the optional IntInf structure defined by the SML'97 basis.
390 :    
391 :     Changed the Rand structure to use words as seeds and results. This also
392 :     fixes bug 1047. (110 patch 3)
393 :    
394 : monnier 8 Added a clear operation to the Queue and various hash table structures.
395 :    
396 :     Changed the ListFormat.formatList to ListFormat.fmt and ListFormat.scanList
397 :     to ListFormat.scan. Added the function ListFormat.listToString.
398 :    
399 :     Updated the HTML library to the final 3.2 specification. This involved adding
400 :     a new BODY element type (with attributes). Also, removed the header/footer
401 :     arguments to the pretty-printer (they were a gross hack).
402 :    
403 :     Added PathUtil structure to Util library. This is a more general version
404 :     of the old UnixPath module.
405 :    
406 :    
407 :     --------------------------------------------------------------------------------
408 :     [1997-10-01] 109.31 --> 109.32
409 :     ------------------------------
410 :    
411 :     Changed the type of the exec instruction in the Reactive library.
412 :    
413 :    
414 :     --------------------------------------------------------------------------------
415 : monnier 2 [1997-09-09] 109.30 --> 109.31
416 :     ------------------------------
417 :    
418 :     Added the Reactive library, which supports reactive scripting. This is a
419 :     first cut, and hasn't been extensively tested.
420 :    
421 :     Changed the names of SockUtil.sock{Recv,Send}* to SockUtil.{recv,send}*
422 :     (since the sock prefix was redundant).
423 :    
424 :     Added some bug fixes to IntListSet that had previously been added to
425 :     the ListSetFn implementation.
426 :    
427 :    
428 :     --------------------------------------------------------------------------------
429 :     [1997-07-17] 109.29 --> 109.30
430 :     ------------------------------
431 :    
432 :     Added a missing case to {ListSetFn,IntListSet}.isSubset.
433 :    
434 :     The bug fix for unionWith was broken. I think I've got it right this
435 :     time.
436 :    
437 :    
438 :     --------------------------------------------------------------------------------
439 :     [1997-07-17] 109.29 --> 109.30
440 :     ------------------------------
441 :    
442 :     Fixed a bug in the binary-tree and splay-tree implementations of the
443 :     unionWith[i] and intersectWith[i] functions. The bug caused the order
444 :     of arguments to the merging function to be wrong in some cases.
445 :    
446 :     Fixed uses of System.Unsafe.
447 :    
448 :     Removed Array2:ARRAY2 from Util library, since the basis now defines these.
449 :    
450 :     Added MonoArrayFn functor for easy creation of monomorphic array structures.
451 :    
452 :     Added Atom.atom' operation for turning substrings into atoms.
453 :    
454 :    
455 :     --------------------------------------------------------------------------------
456 :     [1997-06-13] 109.28 --> 109.29
457 :     ------------------------------
458 :    
459 :     Added collate operation to ORD_MAP signature.
460 :    
461 :     Added compare operation to ORD_SET signature.
462 :    
463 :     Changed the type of and intersectWith[i] in the ORD_MAP signature to be
464 :     more general.
465 :    
466 :     Changed the type of the map function in the ORD_SET signature to return
467 :     a new set (instead of a list).
468 :    
469 :    
470 :     --------------------------------------------------------------------------------
471 :     [1997-05-22] 109.27 --> 109.28
472 :     ------------------------------
473 :    
474 :     Changed various sharing constraints to "where type" definitions to
475 :     compile in SML'97.
476 :    
477 :     Added AtomBinaryMap and AtomBinarySet structures to Util library.
478 :    
479 :    
480 :     --------------------------------------------------------------------------------
481 :     [1997-03-03] 109.25.1 --> 109.25.2
482 :     ----------------------------------
483 :    
484 :     Changed Util/time-limit.sml to reflect new location of callcc/throw.
485 :    
486 :    
487 :     --------------------------------------------------------------------------------
488 :     [1997-02-25] 109.25 --> 109.25.1
489 :     --------------------------------
490 :    
491 :     Added a bunch of new operations to the ordered map modules (BinaryMapFn,
492 :     IntBinaryMap, ListMapFn, IntListFn, and SplayMapFn). The new operations
493 :     are:
494 :     val unionWith : ('a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
495 :     val unionWithi : (Key.ord_key * 'a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
496 :     val intersectWith : ('a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
497 :     val intersectWithi : (Key.ord_key * 'a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
498 :     val filter : ('a -> bool) -> 'a map -> 'a map
499 :     val filteri : (Key.ord_key * 'a -> bool) -> 'a map -> 'a map
500 :     val mapPartial : ('a -> 'b option) -> 'a map -> 'b map
501 :     val mapPartiali : (Key.ord_key * 'a -> 'b option) -> 'a map -> 'b map
502 :    
503 :     Added IOUtil : IO_UTIL structure to the Util library. This provides
504 :     support for dynamically rebinding stdIn and stdOut.
505 :    
506 :     Added KeywordFn functor to the Util library. This provides support for
507 :     implementing scanners, where keyword recognition is done outside the
508 :     basic lexical analysis.
509 :    
510 :     Fixed several bugs in the ListSetFn functor.
511 :    
512 :    
513 :     --------------------------------------------------------------------------------
514 :     [1997-01-10] 109.23 --> 109.24
515 :     ------------------------------
516 :    
517 :     Changed the HASH_TABLE, MONO_HASH_TABLE, MONO_HASH2_TABLE, and ORD_MAP
518 :     interfaces to provide two forms of the listItems function. listItemsi
519 :     returns a list of (key, value) pairs and listItems returns just the values.
520 :     The previous version of listItems was like listItemsi.
521 :    
522 :     Added a missing case for BASEFONT in CheckHTMLFn.check.
523 :    
524 :    
525 :     --------------------------------------------------------------------------------
526 :     [1996-12-07] 109.21.1 --> 109.22
527 :     --------------------------------
528 :    
529 :     Changed the MONO_DYNAMIC_ARRAY signature to make array an eqtype (also changed
530 :     the implementation of DynamicArrayFn).
531 :    
532 :     Fixed a bug in Array2.column
533 :    
534 :    
535 :     --------------------------------------------------------------------------------
536 :     [1996-10-18] 109.19 --> 109.20
537 :     ------------------------------
538 :    
539 :     Added functions for sending/receiving strings over TCP sockets to the
540 :     SockUtil structure.
541 :    
542 :     Fixed a bug with reading on a closed socket in SockUtil.sockRecvVec
543 :    
544 :     Fixed a bug in the implementation of the intersection operation
545 :     in binary sets (BinarySetFn and IntBinarySet).
546 :    
547 :    
548 :     --------------------------------------------------------------------------------
549 :     [1996-10-01] 109.18 --> 109.19

551 :    
552 :     Updated the HTML library to the August 21 version of the 3.2 DTD.
553 :    
554 :     Added html-defaults.sml to the HTML Library.
555 :    
556 :     Added Parsing combinators to the Util library.
557 :    
558 :     Added Socket utilities to the Unix library.
