Original Path: sml/trunk/src/smlnj-lib/CHANGES

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 : mblume 1783 [2005-05-04]
6 :     Added the "join" combinator to ParserComb.
7 :    
8 : jhr 1772 [2005-03-21]
9 :     Fixed a bug in GetOpt.getOpt. The argument processing functions
10 :     for ReqArg and OptArg, and the embedding function for ReturnInOrder
11 :     were getting applied to all arguments, even past a "--".
12 :    
13 : jhr 1756 [2005-02-11]
14 :     Added Atom.same and Atom.lexCompare to the Atom structure. Eventually,
15 :     Atom.sameAtom will be removed.
16 :    
17 : jhr 1732 [2004-12-15]
18 :     Change HashString.hashString' to hashSubstring.
19 :    
20 : mblume 1720 [2004-12-09]
21 :     Added two simple statistics modules:
22 :     * RealOrderStats implements selection of arbitrary order
23 :     statistics as well as the median of an array of reals
24 :     in randomized linear time.
25 :     * UnivariateStats implements mean, variance, standard and average
26 :     deviation, skew, kurtosis, and median of a univariate sample
27 :     (i.e., a set of reals).
28 :    
29 : mblume 1718 [2004-11-29]
30 :     Added HashString.hashString' for substrings.
31 :     Hand-inlined CharVector.fold into HashString for efficiency.
32 :     Modified atom.sml so that Atom.atom' first tries to find an
33 :     existing atom before turning its argument into a string. [-blume]
34 :    
35 : mblume 1350 [2003-09-03]
36 :     Minor modifications to random.sml due to changes to some
37 :     Basis interfaces (slices).
38 :     Significant surgery on bit-array.sml to make it compile with
39 :     new signature MONO_ARRAY. This will require further cleanup
40 :     in the future.
41 : monnier 2
42 : mblume 1350 [2003-08-28]
43 :     Made compilation of int-inf* conditional. (The Basis now has
44 :     a spec-conforming implementation of IntInf, so the one here is
45 :     no longer needed.) [-blume]
46 :    
47 : jhr 1340 [2003-07-31]
48 :     Added getDevice function to PP_STREAM signature.
49 :    
50 : mblume 1335 [2003-05-27]
51 :     Avoid poly-eq in Util/parser-comb.sml.
52 :    
53 : mblume 1334 [2003-05-22]
54 :     More cleanup (all in the name of eliminating incomplete matches):
55 :     - in HTML/html-attrs-fn.sml: fill in missing patterns in two
56 :     case expressions
57 :     - in HTML/html-gram: rewrote function groupDefListContents
58 :     to avoid the (unnecessary) incomplete match
59 :     - in PP/devices/html-dev.sml: made the implementation of popStyle
60 :     agree with the comment above it (popStyle on an empty
61 :     stack is supposed to be a nop)
62 : jhr 1340 - in PP/src/pp-stream-fn.sml: function setSize: handle case of
63 :     an empty scanStk
64 : mblume 1334 - in Util/prime-sizes.sml: raise Fail exceptions instead of
65 :     Match exceptions when reaching the end of a list
66 :     (Perhaps this should eventually be rewritten using an on-demand
67 :     prime-number generator that kicks when needed.)
68 : jhr 751
69 : jhr 1333 [2003-05-22]
70 :     Cleanup logic in Scan.scanf function.
71 :    
72 : jhr 1268 [2002-10-03]
73 :     Fixed bug in formating reals with the %g format.
74 :    
75 : jhr 1248 [2002-06-18]

77 :     Sami Nopanen.
78 :    
79 : jhr 1206 [2002-05-20]
80 : jhr 1209 Fixed bug in IntInf module: scanning of hex literals was not
81 :     handling "0x" prefixes.
82 :    
83 :     [2002-05-20]
84 : jhr 1206 Added ControlUtil module and stringControls function.

89 : jhr 1195
90 :     [2002-05-17]
91 : jhr 1194 Added == and != operators to INT_INF interface. These are a

102 :     combinators to the Util library.
103 :    
104 :     [2002-03-14]

106 :     to this library is likely to change as we get some experience
107 :     with it.
108 :    
109 :     [2002-03-11]
110 :     Added consR1 .. consR5 functions to HashCons library. These
111 :     can be used to hash-cons record types.
112 :    
113 : jhr 1081 [2002-02-21]
114 :     Fixed infinite loop in LeftPriorityQFn.fromList when given a
115 :     singleton list as input (Chris Okasaki provided the fix).
116 : blume 1077
117 :     [2002-02-12]
118 : jhr 1061 Added implementation of priority queues to Util library (using
119 :     Okasaki's leftist-tree implementation).
120 :    
121 : jhr 967 [2001-10-19]
122 :     Added new HashCons library.
123 :    
124 :     [2001-10-19]

135 :     The old interface still works, but will be dropped when we move
136 :     to the new Util library.
137 :    
138 :     [2001-04-06]
139 :     Added partition function to ORD_SET interface.
140 :    
141 :     [2001-04-05]
142 :     Added hasProps function to PropList module.
143 :    
144 :     [2001-03-16]
145 :     Minor bug fix in GetOpt: don't pad the help string, since it causes
146 :     line wraps when one of the help lines is longer than the screen
147 :     width. It was also unneccesary.
148 :    
149 :     [2001-02-23]
150 :     Added inDomain function to the various kinds of hash tables.
151 :    
152 : jhr 785 [2001-02-22]

166 :    
167 : jhr 702 [2000-09-02]
168 :     Added Word versions of hash tables (WordHashTable), finite

170 :    
171 :     [2000-09-02]
172 :     fixed bug in Format module (infinity caused infinite loop).

174 :     [2000-07-19]
175 :     added anchored paths in CM files for NEW_CM.
176 :

188 :    
189 : jhr 596 [2000-04-05]

191 :     of items in the table was not being recomputed.
192 :    
193 :     [2000-04-04]
194 :     Added modify and modifyi iterators to hash tables.
195 :    
196 :     [2000-03-28]
197 :     Added anchorLink style to HTMLDev structure in PP/devices.
198 :    
199 : monnier 498 [1999-12-03]
200 :     Added IntHashTable structure to Util library; this structure is
201 :     a specialization of hash tables to integer keys.
202 : monnier 2
203 : monnier 498 [1999-12-03]
204 :     Added default cases to avoid "match not exhaustive" warnings.
205 :    
206 :     [1999-12-03]
207 :     Added GraphSCCFn functor to Util library, which implements a
208 :     strongly-connected components algorithm on directed graphs (written
209 :     by Matthias Blume).
210 :    
211 :     [1999-11-10]
212 :     Fixed a benign type error in RegExp/BackEnd/fsm.sml that was exposed by
213 :     the previous change.
214 :    
215 :     [1999-11-7]
216 :     Made the result signatures of ListSetFn and ListMapFn opaque.
217 :    
218 :     [1999-11-1]
219 :     Fixed bug in PP/devices/sources.cm under new CM (missing smlnj-lib.cm).
220 :    
221 : monnier 475 [1999-10-20]
222 :     Fixed bug in RedBlack trees (the linear time construction of
223 :     trees from ordered sequences was producing backwards trees).
224 :    
225 :     [1999-10-18]
226 :     Changed UREF signature so that union, unify, and link operations
227 :     now return a boolean.
228 :    
229 :     [1999-10-18]
230 :     Added peekFn to PropList.newProp return result.
231 :    
232 :     [1999-10-14]
233 :     Added TextIOPP structure to pp-lib.cm (it was not being exported).
234 :    
235 : monnier 469 [1999-09-21]
236 :     Changed the getOpt API. Errors are now reported using a callback
237 :     and both usage and getOpt take records as arguments. Also changed
238 :     the NoArg descriptor to take a function so that imperative argument
239 :     processing can be supported.
240 :    
241 :     [1999-09-20]
242 :     Changed CM files to be compatible with both the old (110.0.x) and
243 :     new (110.20+) versions of CM.
244 :    
245 :     [1999-09-17]
246 :     Added PropList:PROP_LIST structure. This structure implements
247 :     property lists using Stephen Weeks's technique.
248 :    
249 :     [1999-09-17]
250 :     Improved the red-black tree implementations with linear-time union,
251 :     intersection, difference, and filter operations. Also reimplemented
252 :     the delete function in a way that does not require an extra constructor.
253 :    
254 :     [1999-09-09]
255 :     Added Red-Black-Tree implementation of sets and maps. Two new
256 :     functors (RedBlackMapFn and RedBlackSetFn) and four new structures
257 :     (IntRedBlackMap, IntRedBlackSet, AtomIntRedBlackMap, and IntRedBlackSet).
258 :     Also added aliases AtomMap and AtomSet that for the RB implementations.
259 :    
260 :     [1999-09-03]
261 :     Added missing support for WORD and WORD8 format items to Format structure.
262 :     Still need to handle LWORD items!!
263 :    
264 :     [1999-08-17]
265 :     Added DynamicArray:DYNAMIC_ARRAY structure.
266 :    
267 : monnier 411 [1999-07-06]
268 :     Added declarative representation of pretty-printing to PPStreamFn.
269 :     This replaces the PPDescFn and PP_DESC components (which were not
270 :     implemented anyway).
271 :    
272 :     [1999-07-02]
273 :     Moved SockUtil structure into a new INet library. Also split out the
274 :     Unix-specific socket operations into a UnixSockUtil module. (Sockets
275 :     are now supported on Win32).
276 :    
277 :     [1999-06-17]
278 :     Added listKeys function to ORD_MAP API.
279 :    
280 :     [1999-06-14]
281 :     Added Riccardo Pucella's GetOpt structure to Util library.
282 :    
283 :     [1999-06-14]
284 :     Added singleton and inDomain functions to ORD_MAP API.
285 :    
286 :     [1999-06-02]
287 :     Merged in some bug fixes from the compiler's version of the IntInf
288 :     structure.
289 :    
290 : monnier 289 [1999-05-05]
291 :     Fixed a couple of bugs in the PP library having to do with nesting
292 :     absolute and relative indentations.
293 :    
294 :     [1999-04-21]
295 :     Added a way to pass control information to a PP device via the PP
296 :     stream (function control in PP_STREAM).
297 :    
298 :     [1999-04-16]
299 :     Added better style support to the HTML PP device.
300 :    
301 :     [1998-09-04]
302 :     Added isEmpty predicate and first fucntion to ORD_MAP
303 :     signature (and to implementations).
304 :    
305 :     [1998-06-23]
306 :     Fixed a bug in ParserComb.bind (reported by Andrew Kennedy).
307 :    
308 :     --------------------------------------------------------------------------------
309 : monnier 106 [1998-04-15] 110 --> 110.5
310 :     --------------------------
311 :    
312 :     There is now a regular expression library (mostly implemented by Riccardo
313 :     Pucella). The implementation separates front-ends (which specify the
314 :     syntax of REs) from back-ends (which implement the matching algorithms).
315 :     Currently, we support AWK syntax as the only front-end and two different
316 :     back-ends.
317 :    
318 :     Added an implementation of the SML/NJ PP API to the pretty-printer examples.
319 :    
320 :     Fixed a bug in the IntInf structure with scanning strings of the form "1+2".
321 :     Also did some clean-up of the code.
322 :    
323 :    
324 :     --------------------------------------------------------------------------------
325 : monnier 8 [1997-12-07] 109.32 --> 110
326 :     ---------------------------
327 :    
328 : monnier 29 Added the function add' to the ORD_SET signature and the function insert'
329 :     to the ORD_MAP signature. These functions fit the pattern of the fold
330 :     functions. (110 patch 3)
331 :    
332 :     Added the IntInf:INT_INF structure to the Util library. This is a subset
333 :     of the optional IntInf structure defined by the SML'97 basis.
334 :    
335 :     Changed the Rand structure to use words as seeds and results. This also
336 :     fixes bug 1047. (110 patch 3)
337 :    
338 : monnier 8 Added a clear operation to the Queue and various hash table structures.
339 :    
340 :     Changed the ListFormat.formatList to ListFormat.fmt and ListFormat.scanList
341 :     to ListFormat.scan. Added the function ListFormat.listToString.
342 :    
343 :     Updated the HTML library to the final 3.2 specification. This involved adding
344 :     a new BODY element type (with attributes). Also, removed the header/footer
345 :     arguments to the pretty-printer (they were a gross hack).
346 :    
347 :     Added PathUtil structure to Util library. This is a more general version
348 :     of the old UnixPath module.
349 :    
350 :    
351 :     --------------------------------------------------------------------------------
352 :     [1997-10-01] 109.31 --> 109.32
353 :     ------------------------------
354 :    
355 :     Changed the type of the exec instruction in the Reactive library.
356 :    
357 :    
358 :     --------------------------------------------------------------------------------
359 : monnier 2 [1997-09-09] 109.30 --> 109.31
360 :     ------------------------------
361 :    
362 :     Added the Reactive library, which supports reactive scripting. This is a
363 :     first cut, and hasn't been extensively tested.
364 :    
365 :     Changed the names of SockUtil.sock{Recv,Send}* to SockUtil.{recv,send}*
366 :     (since the sock prefix was redundant).
367 :    
368 :     Added some bug fixes to IntListSet that had previously been added to
369 :     the ListSetFn implementation.
370 :    
371 :    
372 :     --------------------------------------------------------------------------------
373 :     [1997-07-17] 109.29 --> 109.30
374 :     ------------------------------
375 :    
376 :     Added a missing case to {ListSetFn,IntListSet}.isSubset.
377 :    
378 :     The bug fix for unionWith was broken. I think I've got it right this
379 :     time.
380 :    
381 :    
382 :     --------------------------------------------------------------------------------
383 :     [1997-07-17] 109.29 --> 109.30
384 :     ------------------------------
385 :    
386 :     Fixed a bug in the binary-tree and splay-tree implementations of the
387 :     unionWith[i] and intersectWith[i] functions. The bug caused the order
388 :     of arguments to the merging function to be wrong in some cases.
389 :    
390 :     Fixed uses of System.Unsafe.
391 :    
392 :     Removed Array2:ARRAY2 from Util library, since the basis now defines these.
393 :    
394 :     Added MonoArrayFn functor for easy creation of monomorphic array structures.
395 :    
396 :     Added Atom.atom' operation for turning substrings into atoms.
397 :    
398 :    
399 :     --------------------------------------------------------------------------------
400 :     [1997-06-13] 109.28 --> 109.29
401 :     ------------------------------
402 :    
403 :     Added collate operation to ORD_MAP signature.
404 :    
405 :     Added compare operation to ORD_SET signature.
406 :    
407 :     Changed the type of and intersectWith[i] in the ORD_MAP signature to be
408 :     more general.
409 :    
410 :     Changed the type of the map function in the ORD_SET signature to return
411 :     a new set (instead of a list).
412 :    
413 :    
414 :     --------------------------------------------------------------------------------
415 :     [1997-05-22] 109.27 --> 109.28
416 :     ------------------------------
417 :    
418 :     Changed various sharing constraints to "where type" definitions to
419 :     compile in SML'97.
420 :    
421 :     Added AtomBinaryMap and AtomBinarySet structures to Util library.
422 :    
423 :    
424 :     --------------------------------------------------------------------------------
425 :     [1997-03-03] 109.25.1 --> 109.25.2
426 :     ----------------------------------
427 :    
428 :     Changed Util/time-limit.sml to reflect new location of callcc/throw.
429 :    
430 :    
431 :     --------------------------------------------------------------------------------
432 :     [1997-02-25] 109.25 --> 109.25.1
433 :     --------------------------------
434 :    
435 :     Added a bunch of new operations to the ordered map modules (BinaryMapFn,
436 :     IntBinaryMap, ListMapFn, IntListFn, and SplayMapFn). The new operations
437 :     are:
438 :     val unionWith : ('a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
439 :     val unionWithi : (Key.ord_key * 'a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
440 :     val intersectWith : ('a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
441 :     val intersectWithi : (Key.ord_key * 'a * 'a -> 'a) -> ('a map * 'a map) -> 'a map
442 :     val filter : ('a -> bool) -> 'a map -> 'a map
443 :     val filteri : (Key.ord_key * 'a -> bool) -> 'a map -> 'a map
444 :     val mapPartial : ('a -> 'b option) -> 'a map -> 'b map
445 :     val mapPartiali : (Key.ord_key * 'a -> 'b option) -> 'a map -> 'b map

447 :     Added IOUtil : IO_UTIL structure to the Util library. This provides
448 :     support for dynamically rebinding stdIn and stdOut.
449 :    
450 :     Added KeywordFn functor to the Util library. This provides support for
451 :     implementing scanners, where keyword recognition is done outside the
452 :     basic lexical analysis.
453 :    
454 :     Fixed several bugs in the ListSetFn functor.

459 :     ------------------------------
460 :    
461 :     Changed the HASH_TABLE, MONO_HASH_TABLE, MONO_HASH2_TABLE, and ORD_MAP
462 :     interfaces to provide two forms of the listItems function. listItemsi
463 :     returns a list of (key, value) pairs and listItems returns just the values.
464 :     The previous version of listItems was like listItemsi.
465 :    
466 :     Added a missing case for BASEFONT in CheckHTMLFn.check.

485 :    
486 :     Fixed a bug with reading on a closed socket in SockUtil.sockRecvVec
487 :    
488 :     Fixed a bug in the implementation of the intersection operation
489 :     in binary sets (BinarySetFn and IntBinarySet).
