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

121 :     Sami Nopanen.
122 :    
123 : jhr 1206 [2002-05-20]
124 : jhr 1209 Fixed bug in IntInf module: scanning of hex literals was not
125 :     handling "0x" prefixes.
126 :    
127 :     [2002-05-20]

133 : jhr 1195
134 :     [2002-05-17]
135 : jhr 1194 Added == and != operators to INT_INF interface. These are a

146 :     combinators to the Util library.
147 :    
148 :     [2002-03-14]

150 :     to this library is likely to change as we get some experience
151 :     with it.
152 :    
153 :     [2002-03-11]
154 :     Added consR1 .. consR5 functions to HashCons library. These

156 :    
157 : jhr 1081 [2002-02-21]
158 :     Fixed infinite loop in LeftPriorityQFn.fromList when given a
159 :     singleton list as input (Chris Okasaki provided the fix).
160 : blume 1077
161 :     [2002-02-12]
162 : jhr 1061 Added implementation of priority queues to Util library (using

176 :    
177 : jhr 816 [2001-05-04]
178 :     Modified GraphSCC module to support a list of roots (Blume).
179 :     The old interface still works, but will be dropped when we move
180 :     to the new Util library.
181 :    
182 :     [2001-04-06]
183 :     Added partition function to ORD_SET interface.
184 :    
185 :     [2001-04-05]
186 :     Added hasProps function to PropList module.
187 :    
188 :     [2001-03-16]
189 :     Minor bug fix in GetOpt: don't pad the help string, since it causes
190 :     line wraps when one of the help lines is longer than the screen
191 :     width. It was also unneccesary.
192 :    
193 :     [2001-02-23]
194 :     Added inDomain function to the various kinds of hash tables.
195 :    
196 : jhr 785 [2001-02-22]

210 :    
211 : jhr 702 [2000-09-02]
212 :     Added Word versions of hash tables (WordHashTable), finite

214 :    
215 :     [2000-09-02]
216 :     fixed bug in Format module (infinity caused infinite loop).

218 :     [2000-07-19]
219 :     added anchored paths in CM files for NEW_CM.
220 :    
221 : jhr 688 [2000-06-30]

232 :    
233 : jhr 596 [2000-04-05]
234 :     Fixed a bug in the filter/filteri hash table functions: the number
235 :     of items in the table was not being recomputed.
236 :    
237 :     [2000-04-04]
238 :     Added modify and modifyi iterators to hash tables.
239 :    
240 :     [2000-03-28]
241 :     Added anchorLink style to HTMLDev structure in PP/devices.
242 :    
243 : monnier 498 [1999-12-03]
244 :     Added IntHashTable structure to Util library; this structure is
245 :     a specialization of hash tables to integer keys.
246 : monnier 2
247 : monnier 498 [1999-12-03]
248 :     Added default cases to avoid "match not exhaustive" warnings.
249 :    
250 :     [1999-12-03]
251 :     Added GraphSCCFn functor to Util library, which implements a
252 :     strongly-connected components algorithm on directed graphs (written

256 :     Fixed a benign type error in RegExp/BackEnd/fsm.sml that was exposed by
257 :     the previous change.
258 :    
259 :     [1999-11-7]

262 :     [1999-11-1]
263 :     Fixed bug in PP/devices/sources.cm under new CM (missing smlnj-lib.cm).
264 :    
265 : monnier 475 [1999-10-20]
266 :     Fixed bug in RedBlack trees (the linear time construction of
267 :     trees from ordered sequences was producing backwards trees).
268 :    
269 :     [1999-10-18]
270 :     Changed UREF signature so that union, unify, and link operations
271 :     now return a boolean.
272 :    
273 :     [1999-10-18]
274 :     Added peekFn to PropList.newProp return result.
275 :    
276 :     [1999-10-14]
277 :     Added TextIOPP structure to pp-lib.cm (it was not being exported).
278 :    
279 : monnier 469 [1999-09-21]
280 :     Changed the getOpt API. Errors are now reported using a callback
281 :     and both usage and getOpt take records as arguments. Also changed
282 :     the NoArg descriptor to take a function so that imperative argument
283 :     processing can be supported.
284 :    
285 :     [1999-09-20]
286 :     Changed CM files to be compatible with both the old (110.0.x) and
287 :     new (110.20+) versions of CM.
288 :    
289 :     [1999-09-17]
290 :     Added PropList:PROP_LIST structure. This structure implements
291 :     property lists using Stephen Weeks's technique.
292 :    
293 :     [1999-09-17]
294 :     Improved the red-black tree implementations with linear-time union,
295 :     intersection, difference, and filter operations. Also reimplemented
296 :     the delete function in a way that does not require an extra constructor.
297 :    
298 :     [1999-09-09]
299 :     Added Red-Black-Tree implementation of sets and maps. Two new
300 :     functors (RedBlackMapFn and RedBlackSetFn) and four new structures
301 :     (IntRedBlackMap, IntRedBlackSet, AtomIntRedBlackMap, and IntRedBlackSet).
302 :     Also added aliases AtomMap and AtomSet that for the RB implementations.
303 :    
304 :     [1999-09-03]
305 :     Added missing support for WORD and WORD8 format items to Format structure.
306 :     Still need to handle LWORD items!!
307 :    
308 :     [1999-08-17]
309 :     Added DynamicArray:DYNAMIC_ARRAY structure.
310 :    
311 : monnier 411 [1999-07-06]
312 :     Added declarative representation of pretty-printing to PPStreamFn.
313 :     This replaces the PPDescFn and PP_DESC components (which were not
314 :     implemented anyway).
315 :    
316 :     [1999-07-02]
317 :     Moved SockUtil structure into a new INet library. Also split out the
318 :     Unix-specific socket operations into a UnixSockUtil module. (Sockets
319 :     are now supported on Win32).
320 :    
321 :     [1999-06-17]
322 :     Added listKeys function to ORD_MAP API.
323 :    
324 :     [1999-06-14]
325 :     Added Riccardo Pucella's GetOpt structure to Util library.
326 :    
327 :     [1999-06-14]
328 :     Added singleton and inDomain functions to ORD_MAP API.
329 :    
330 :     [1999-06-02]
331 :     Merged in some bug fixes from the compiler's version of the IntInf
332 :     structure.
333 :    
334 : monnier 289 [1999-05-05]
335 :     Fixed a couple of bugs in the PP library having to do with nesting
336 :     absolute and relative indentations.
337 :    
338 :     [1999-04-21]
339 :     Added a way to pass control information to a PP device via the PP
340 :     stream (function control in PP_STREAM).
341 :    
342 :     [1999-04-16]
343 :     Added better style support to the HTML PP device.
344 :    
345 :     [1998-09-04]
346 :     Added isEmpty predicate and first fucntion to ORD_MAP
347 :     signature (and to implementations).
348 :    
349 :     [1998-06-23]
350 :     Fixed a bug in ParserComb.bind (reported by Andrew Kennedy).
351 :    
352 :     --------------------------------------------------------------------------------
353 : monnier 106 [1998-04-15] 110 --> 110.5
354 :     --------------------------
355 :    
356 :     There is now a regular expression library (mostly implemented by Riccardo
357 :     Pucella). The implementation separates front-ends (which specify the
358 :     syntax of REs) from back-ends (which implement the matching algorithms).
359 :     Currently, we support AWK syntax as the only front-end and two different
360 :     back-ends.
361 :    
362 :     Added an implementation of the SML/NJ PP API to the pretty-printer examples.
363 :    
364 :     Fixed a bug in the IntInf structure with scanning strings of the form "1+2".
365 :     Also did some clean-up of the code.
366 :    
367 :    
368 :     --------------------------------------------------------------------------------
369 : monnier 8 [1997-12-07] 109.32 --> 110
370 :     ---------------------------
371 :    
372 : monnier 29 Added the function add' to the ORD_SET signature and the function insert'
373 :     to the ORD_MAP signature. These functions fit the pattern of the fold
374 :     functions. (110 patch 3)
375 :    
376 :     Added the IntInf:INT_INF structure to the Util library. This is a subset
377 :     of the optional IntInf structure defined by the SML'97 basis.
378 :    
379 :     Changed the Rand structure to use words as seeds and results. This also
380 :     fixes bug 1047. (110 patch 3)
381 :    
382 : monnier 8 Added a clear operation to the Queue and various hash table structures.
383 :    
384 :     Changed the ListFormat.formatList to ListFormat.fmt and ListFormat.scanList
385 :     to ListFormat.scan. Added the function ListFormat.listToString.
386 :    
387 :     Updated the HTML library to the final 3.2 specification. This involved adding
388 :     a new BODY element type (with attributes). Also, removed the header/footer
389 :     arguments to the pretty-printer (they were a gross hack).
390 :    
391 :     Added PathUtil structure to Util library. This is a more general version
392 :     of the old UnixPath module.
393 :    
394 :    
395 :     --------------------------------------------------------------------------------
396 :     [1997-10-01] 109.31 --> 109.32
397 :     ------------------------------
398 :    
399 :     Changed the type of the exec instruction in the Reactive library.
400 :    
401 :    
402 :     --------------------------------------------------------------------------------
403 : monnier 2 [1997-09-09] 109.30 --> 109.31
404 :     ------------------------------
405 :    
406 :     Added the Reactive library, which supports reactive scripting. This is a
407 :     first cut, and hasn't been extensively tested.
408 :    
409 :     Changed the names of SockUtil.sock{Recv,Send}* to SockUtil.{recv,send}*
410 :     (since the sock prefix was redundant).
411 :    
412 :     Added some bug fixes to IntListSet that had previously been added to
413 :     the ListSetFn implementation.
414 :    
415 :    
416 :     --------------------------------------------------------------------------------
417 :     [1997-07-17] 109.29 --> 109.30
418 :     ------------------------------
419 :    
420 :     Added a missing case to {ListSetFn,IntListSet}.isSubset.
421 :    
422 :     The bug fix for unionWith was broken. I think I've got it right this
423 :     time.
424 :    
425 :    
426 :     --------------------------------------------------------------------------------
427 :     [1997-07-17] 109.29 --> 109.30
428 :     ------------------------------
429 :    
430 :     Fixed a bug in the binary-tree and splay-tree implementations of the
431 :     unionWith[i] and intersectWith[i] functions. The bug caused the order
432 :     of arguments to the merging function to be wrong in some cases.
433 :    
434 :     Fixed uses of System.Unsafe.
435 :    
436 :     Removed Array2:ARRAY2 from Util library, since the basis now defines these.
437 :    
438 :     Added MonoArrayFn functor for easy creation of monomorphic array structures.
439 :    
440 :     Added Atom.atom' operation for turning substrings into atoms.
441 :    
442 :    
443 :     --------------------------------------------------------------------------------
444 :     [1997-06-13] 109.28 --> 109.29
445 :     ------------------------------
446 :    
447 :     Added collate operation to ORD_MAP signature.
448 :    
449 :     Added compare operation to ORD_SET signature.
450 :    
451 :     Changed the type of and intersectWith[i] in the ORD_MAP signature to be
452 :     more general.
453 :    
454 :     Changed the type of the map function in the ORD_SET signature to return
455 :     a new set (instead of a list).
456 :    
457 :    
458 :     --------------------------------------------------------------------------------
459 :     [1997-05-22] 109.27 --> 109.28
460 :     ------------------------------
461 :    
462 :     Changed various sharing constraints to "where type" definitions to
463 :     compile in SML'97.
464 :    
465 :     Added AtomBinaryMap and AtomBinarySet structures to Util library.
466 :    
467 :    
468 :     --------------------------------------------------------------------------------
469 :     [1997-03-03] 109.25.1 --> 109.25.2
470 :     ----------------------------------
471 :    
472 :     Changed Util/time-limit.sml to reflect new location of callcc/throw.
473 :    
474 :    
475 :     --------------------------------------------------------------------------------
476 :     [1997-02-25] 109.25 --> 109.25.1
477 :     --------------------------------
478 :    
479 :     Added a bunch of new operations to the ordered map modules (BinaryMapFn,
480 :     IntBinaryMap, ListMapFn, IntListFn, and SplayMapFn). The new operations
481 :     are:
482 :     val unionWith : ('a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
483 :     val unionWithi : (Key.ord_key * 'a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
484 :     val intersectWith : ('a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
485 :     val intersectWithi : (Key.ord_key * 'a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
486 :     val filter : ('a -> bool) -> 'a map -> 'a map
487 :     val filteri : (Key.ord_key * 'a -> bool) -> 'a map -> 'a map
488 :     val mapPartial : ('a -> 'b option) -> 'a map -> 'b map
489 :     val mapPartiali : (Key.ord_key * 'a -> 'b option) -> 'a map -> 'b map
490 :    
491 :     Added IOUtil : IO_UTIL structure to the Util library. This provides
492 :     support for dynamically rebinding stdIn and stdOut.
493 :    
494 :     Added KeywordFn functor to the Util library. This provides support for
495 :     implementing scanners, where keyword recognition is done outside the
496 :     basic lexical analysis.
497 :    
498 :     Fixed several bugs in the ListSetFn functor.
499 :    
500 :    
501 :     --------------------------------------------------------------------------------
502 :     [1997-01-10] 109.23 --> 109.24
503 :     ------------------------------
504 :    
505 :     Changed the HASH_TABLE, MONO_HASH_TABLE, MONO_HASH2_TABLE, and ORD_MAP
506 :     interfaces to provide two forms of the listItems function. listItemsi
507 :     returns a list of (key, value) pairs and listItems returns just the values.
508 :     The previous version of listItems was like listItemsi.
509 :    
510 :     Added a missing case for BASEFONT in CheckHTMLFn.check.
511 :    
512 :    
513 :     --------------------------------------------------------------------------------
514 :     [1996-12-07] 109.21.1 --> 109.22
515 :     --------------------------------
516 :    
517 :     Changed the MONO_DYNAMIC_ARRAY signature to make array an eqtype (also changed
518 :     the implementation of DynamicArrayFn).
519 :    
520 :     Fixed a bug in Array2.column
521 :    
522 :    
523 :     --------------------------------------------------------------------------------
524 :     [1996-10-18] 109.19 --> 109.20
525 :     ------------------------------
526 :    
527 :     Added functions for sending/receiving strings over TCP sockets to the
528 :     SockUtil structure.
529 :    
530 :     Fixed a bug with reading on a closed socket in SockUtil.sockRecvVec
531 :    
532 :     Fixed a bug in the implementation of the intersection operation
533 :     in binary sets (BinarySetFn and IntBinarySet).
534 :    
535 :    
536 :     --------------------------------------------------------------------------------
537 :     [1996-10-01] 109.18 --> 109.19

540 :     Updated the HTML library to the August 21 version of the 3.2 DTD.
541 :    
542 :     Added html-defaults.sml to the HTML Library.
543 :    
544 :     Added Parsing combinators to the Util library.
545 :    
546 :     Added Socket utilities to the Unix library.
