3    --------------------------------------------------------------------------------
4    
5    [2007-12-13]
6            Also added list' and listg' which are parameterized over the delimiter-
7            and separator strings used for formatting lists.  (The default for "list" and
8            "listg" is the usuas "[" ", " "]".)
9    
10    [2007-12-13]
11            Added "elem" function as an inverse to "glue" to FormatComb module.
12            This makes writing extensions possible.  Also added "list" and "option"
13            combinators for formatting list- and option types.
14    
15    [2007-11-02]
16            A collection of bug fixes for machine.sml in the Reactive library.
17            (Thanks to Timothy Bourke)
18    
19    [2007-05-15]
20            Made the UnixPath.path_list type concrete (= string list).
21    
22    [2007-04-24]
23            Added next function to Fifo and Queue modules.
24    
25    [2007-02-15]
26            Removed vestigial IntInf and INT_INF definitions.
27    
28    [2007-02-14]
29            Changed the representation type of UTF8.wchar from Word32.word to word.
30            Also added the UTF8.maxCodePoint value.
31    
32    [2007-01-30]
33            Added the lookup function to the ORD_MAP interface.
34    
35    [2007-01-30]
36            Added the fromList function to the ORD_SET interface.  For the red-black
37            tree and list based implementations, this operation is linear for ordered
38            inputs.
39    
40    [2007-01-28]
41            Added UTF8 signature and structure.
42    
43    [2005-11-07]
44            Internal change: replaced uses of the depreciated Substring.all
45            with the Substring.full
46    
47    [2005-11-05]
48            Tweaking of the interval set API.  Added iterators on items and
49            changed the iterators on intervals to have a "Int" suffix.
50            Changed addInterval to addInt, changed list to intervals.  Added
51            the items function.
52    
53    [2005-10-31]
54            Fixed a bug in IntervalSetFn().intersect.
55    
56    [2005-10-25]
57            Added interval sets to utility library (signatures INTERVAL_DOMAIN
58            and INTERVAL_SET, and functor IntervalSetFn).
59    
60    [2005-08-04]
61            Renamed graph-scc.sml to graph-scc-fn.sml.
62    
63    [2005-07-23]
64            Fix PP library to export ANSITermDev, ANSITermPP, PPDescFn, and
65            PP_DESC.  Also add nbSpace to PP_DESC signature.
66    
67    [2005-07-12]
68            Added ANSITermDev device that uses ANSI terminal display attributes
69            and added a ANSITermPP for pretty printing to such a device.
70    
71    [2005-07-06]
72            Added ANSITerm structure, which provides support for ANSI terminal
73            display attributes (e.g., red text).
74    
75    [2005-07-06]
76            Refactored the pretty printing library.  The declarative way to
77            construct pretty-printing descriptions now sits on top of the
78            PP_STREAM interface.  Also removed "onNewline" function, which
79            was not implemented.
80    
81    [2005-05-05]
82            Added singleton function to MONO_PRIORITYQ interface.
83    
84    [2005-05-04]
85            Added the "join" combinator to ParserComb.
86    
87    [2005-03-21]
88            Fixed a bug in GetOpt.getOpt.  The argument processing functions
89            for ReqArg and OptArg, and the embedding function for ReturnInOrder
90            were getting applied to all arguments, even past a "--".
91    
92    [2005-02-11]
93            Added Atom.same and Atom.lexCompare to the Atom structure.  Eventually,
94            Atom.sameAtom will be removed.
95    
96    [2004-12-15]
97            Change HashString.hashString' to hashSubstring.
98    
99    [2004-12-09]
100            Added two simple statistics modules:
101            * RealOrderStats implements selection of arbitrary order
102              statistics as well as the median of an array of reals
103              in randomized linear time.
104            * UnivariateStats implements mean, variance, standard and average
105              deviation, skew, kurtosis, and median of a univariate sample
106              (i.e., a set of reals).
107    
108    [2004-11-29]
109            Added HashString.hashString' for substrings.
110            Hand-inlined CharVector.fold into HashString for efficiency.
111            Modified atom.sml so that Atom.atom' first tries to find an
112            existing atom before turning its argument into a string. [-blume]
113    
114    [2003-09-03]
115            Minor modifications to random.sml due to changes to some
116            Basis interfaces (slices).
117            Significant surgery on bit-array.sml to make it compile with
118            new signature MONO_ARRAY.  This will require further cleanup
119            in the future.
120    
121    [2003-08-28]
122            Made compilation of int-inf* conditional.  (The Basis now has
123            a spec-conforming implementation of IntInf, so the one here is
124            no longer needed.)  [-blume]
125    
126    [2003-07-31]
127            Added getDevice function to PP_STREAM signature.
128    
129    [2003-05-27]
130            Avoid poly-eq in Util/parser-comb.sml.
131    
132    [2003-05-22]
133            More cleanup (all in the name of eliminating incomplete matches):
134              - in HTML/html-attrs-fn.sml: fill in missing patterns in two
135                case expressions
136              - in HTML/html-gram: rewrote function groupDefListContents
137                to avoid the (unnecessary) incomplete match
138              - in PP/devices/html-dev.sml: made the implementation of popStyle
139                agree with the comment above it (popStyle on an empty
140                stack is supposed to be a nop)
141              - in PP/src/pp-stream-fn.sml: function setSize: handle case of
142                an empty scanStk
143              - in Util/prime-sizes.sml: raise Fail exceptions instead of
144                Match exceptions when reaching the end of a list
145                (Perhaps this should eventually be rewritten using an on-demand
146                 prime-number generator that kicks when needed.)
147    
148    [2003-05-22]
149            Cleanup logic in Scan.scanf function.
150    
151    [2002-10-03]
152            Fixed bug in formating reals with the %g format.
153    
154    [2002-06-18]
155            Fixed a bug in MatchTree.nth (regexp library).  Thanks to
156            Sami Nopanen.
157    
158    [2002-05-20]
159            Fixed bug in IntInf module: scanning of hex literals was not
160            handling "0x" prefixes.
161    
162    [2002-05-20]
163            Added ControlUtil module and stringControls function.
164    
165    [2002-05-17]
166            Added tyName field to ValueSyntax exception in Controls module
167            and path field to registry tree in ControlRegistry module.
168    
169    [2002-05-17]
170            Added == and != operators to INT_INF interface.  These are a
171            placeholder until IntInf moves into the SML/NJ compiler.
172    
173    [2002-05-16]
174            Added mergeWith function to ORD_MAP interface.
175    
176    [2002-05-15]
177            Revised Controls library.
178    
179    [2002-04-17]
180            Added Matthias Blume's implementation of Danvey-style format
181            combinators to the Util library.
182    
183    [2002-03-14]
184            Merged in Matthias Blume's Controls library.  Warning: the API
185            to this library is likely to change as we get some experience
186            with it.
187    
188    [2002-03-11]
189            Added consR1 .. consR5 functions to HashCons library.  These
190            can be used to hash-cons record types.
191    
192    [2002-02-21]
193            Fixed infinite loop in LeftPriorityQFn.fromList when given a
194            singleton list as input (Chris Okasaki provided the fix).
195    
196    [2002-02-12]
197            Added implementation of priority queues to Util library (using
198            Okasaki's leftist-tree implementation).
199    
200    [2001-10-19]
201            Added new HashCons library.
202    
203    [2001-10-19]
204            Added PrimeSizes module to Util library.
205    
206    [2001-09-27]
207            Fixed bug in UnixEnv module (reported by Leunga).
208    
209    [2001-05-05]
210            Added addrToString function to SockUtil module in INet library.
211    
212    [2001-05-04]
213            Modified GraphSCC module to support a list of roots (Blume).
214            The old interface still works, but will be dropped when we move
215            to the new Util library.
216    
217    [2001-04-06]
218            Added partition function to ORD_SET interface.
219    
220    [2001-04-05]
221            Added hasProps function to PropList module.
222    
223    [2001-03-16]
224            Minor bug fix in GetOpt: don't pad the help string, since it causes
225            line wraps when one of the help lines is longer than the screen
226            width.  It was also unneccesary.
227    
228    [2001-02-23]
229            Added inDomain function to the various kinds of hash tables.
230    
231    [2001-02-22]
232            Fixed bug in {Int,Word}RedBlackMapFn.insert (bug 1591).
233    
234    [2000-12-13]
235            Added the bit operations to the IntInf module (Leung).
236    
237    [2000-11-17]
238            Added where clause to GraphSCCFn result signature (Blume).
239    
240    [2000-10-20]
241            Made the result signature of the RegExpFn functor be opaque.
242    
243    [2000-09-28]
244            SML/NJ 110.0.7 release.
245    
246    [2000-09-02]
247            Added Word versions of hash tables (WordHashTable), finite
248            maps (WordRedBlackMap), and sets (WordRedBlackSet).
249    
250    [2000-09-02]
251            fixed bug in Format module (infinity caused infinite loop).
252    
253    [2000-07-19]
254            added anchored paths in CM files for NEW_CM.
255    
256    [2000-06-30]
257            added implementation of LWORD in Format module.
258    
259    [2000-05-16]
260            Fixed bug in dfa-engine.sml (bug number 1559).
261    
262    [2000-05-08]
263            Added setFn to PList.newProp return type.
264    
265    [2000-05-05]
266            Added sameHolder function to PropList module.
267    
268    [2000-04-05]
269            Fixed a bug in the filter/filteri hash table functions: the number
270            of items in the table was not being recomputed.
271    
272    [2000-04-04]
273            Added modify and modifyi iterators to hash tables.
274    
275    [2000-03-28]
276            Added anchorLink style to HTMLDev structure in PP/devices.
277    
278    [1999-12-03]
279            Added IntHashTable structure to Util library; this structure is
280            a specialization of hash tables to integer keys.
281    
282    [1999-12-03]
283            Added default cases to avoid "match not exhaustive" warnings.
284    
285    [1999-12-03]
286            Added GraphSCCFn functor to Util library, which implements a
287            strongly-connected components algorithm on directed graphs (written
288            by Matthias Blume).
289    
290    [1999-11-10]
291            Fixed a benign type error in RegExp/BackEnd/fsm.sml that was exposed by
292            the previous change.
293    
294    [1999-11-7]
295            Made the result signatures of ListSetFn and ListMapFn opaque.
296    
297    [1999-11-1]
298            Fixed bug in PP/devices/sources.cm under new CM (missing smlnj-lib.cm).
299    
300    [1999-10-20]
301            Fixed bug in RedBlack trees (the linear time construction of
302            trees from ordered sequences was producing backwards trees).
303    
304    [1999-10-18]
305            Changed UREF signature so that union, unify, and link operations
306            now return a boolean.
307    
308    [1999-10-18]
309            Added peekFn to PropList.newProp return result.
310    
311    [1999-10-14]
312            Added TextIOPP structure to pp-lib.cm (it was not being exported).
313    
314    [1999-09-21]
315            Changed the getOpt API.  Errors are now reported using a callback
316            and both usage and getOpt take records as arguments.  Also changed
317            the NoArg descriptor to take a function so that imperative argument
318            processing can be supported.
319    
320    [1999-09-20]
321            Changed CM files to be compatible with both the old (110.0.x) and
322            new (110.20+) versions of CM.
323    
324    [1999-09-17]
325            Added PropList:PROP_LIST structure.  This structure implements
326            property lists using Stephen Weeks's technique.
327    
328    [1999-09-17]
329            Improved the red-black tree implementations with linear-time union,
330            intersection, difference, and filter operations.  Also reimplemented
331            the delete function in a way that does not require an extra constructor.
332    
333    [1999-09-09]
334            Added Red-Black-Tree implementation of sets and maps.  Two new
335            functors (RedBlackMapFn and RedBlackSetFn) and four new structures
336            (IntRedBlackMap, IntRedBlackSet, AtomIntRedBlackMap, and IntRedBlackSet).
337            Also added aliases AtomMap and AtomSet that for the RB implementations.
338    
339    [1999-09-03]
340            Added missing support for WORD and WORD8 format items to Format structure.
341            Still need to handle LWORD items!!
342    
343    [1999-08-17]
344            Added DynamicArray:DYNAMIC_ARRAY structure.
345    
346    [1999-07-06]
347            Added declarative representation of pretty-printing to PPStreamFn.
348            This replaces the PPDescFn and PP_DESC components (which were not
349            implemented anyway).
350    
351    [1999-07-02]
352            Moved SockUtil structure into a new INet library.  Also split out the
353            Unix-specific socket operations into a UnixSockUtil module.  (Sockets
354            are now supported on Win32).
355    
356    [1999-06-17]
357            Added listKeys function to ORD_MAP API.
358    
359    [1999-06-14]
360            Added Riccardo Pucella's GetOpt structure to Util library.
361    
362    [1999-06-14]
363            Added singleton and inDomain functions to ORD_MAP API.
364    
365    [1999-06-02]
366            Merged in some bug fixes from the compiler's version of the IntInf
367            structure.
368    
369    [1999-05-05]
370            Fixed a couple of bugs in the PP library having to do with nesting
371            absolute and relative indentations.
372    
373    [1999-04-21]
374            Added a way to pass control information to a PP device via the PP
375            stream (function control in PP_STREAM).
376    
377    [1999-04-16]
378            Added better style support to the HTML PP device.
379    
380    [1998-09-04]
381            Added isEmpty predicate and first fucntion to ORD_MAP
382            signature (and to implementations).
383    
384    [1998-06-23]
385            Fixed a bug in ParserComb.bind (reported by Andrew Kennedy).
386    
387    --------------------------------------------------------------------------------
388    [1998-04-15] 110 --> 110.5
389    --------------------------
390    
391    There is now a regular expression library (mostly implemented by Riccardo
392    Pucella).  The implementation separates front-ends (which specify the
393    syntax of REs) from back-ends (which implement the matching algorithms).
394    Currently, we support AWK syntax as the only front-end and two different
395    back-ends.
396    
397    Added an implementation of the SML/NJ PP API to the pretty-printer examples.
398    
399    Fixed a bug in the IntInf structure with scanning strings of the form "1+2".
400    Also did some clean-up of the code.
