3    --------------------------------------------------------------------------------
4    
5    [2007-10-02]
6            A collection of bug fixes for machine.sml in the Reactive library.
7            (Thanks to Timothy Bourke)
8    
9    [2007-05-15]
10            Made the UnixPath.path_list type concrete (= string list).
11    
12    [2007-04-24]
13            Added next function to Fifo and Queue modules.
14    
15    [2007-02-15]
16            Removed vestigial IntInf and INT_INF definitions.
17    
18    [2007-02-14]
19            Changed the representation type of UTF8.wchar from Word32.word to word.
20            Also added the UTF8.maxCodePoint value.
21    
22    [2007-01-30]
23            Added the lookup function to the ORD_MAP interface.
24    
25    [2007-01-30]
26            Added the fromList function to the ORD_SET interface.  For the red-black
27            tree and list based implementations, this operation is linear for ordered
28            inputs.
29    
30    [2007-01-28]
31            Added UTF8 signature and structure.
32    
33    [2005-11-07]
34            Internal change: replaced uses of the depreciated Substring.all
35            with the Substring.full
36    
37    [2005-11-05]
38            Tweaking of the interval set API.  Added iterators on items and
39            changed the iterators on intervals to have a "Int" suffix.
40            Changed addInterval to addInt, changed list to intervals.  Added
41            the items function.
42    
43    [2005-10-31]
44            Fixed a bug in IntervalSetFn().intersect.
45    
46    [2005-10-25]
47            Added interval sets to utility library (signatures INTERVAL_DOMAIN
48            and INTERVAL_SET, and functor IntervalSetFn).
49    
50    [2005-08-04]
51            Renamed graph-scc.sml to graph-scc-fn.sml.
52    
53    [2005-07-23]
54            Fix PP library to export ANSITermDev, ANSITermPP, PPDescFn, and
55            PP_DESC.  Also add nbSpace to PP_DESC signature.
56    
57    [2005-07-12]
58            Added ANSITermDev device that uses ANSI terminal display attributes
59            and added a ANSITermPP for pretty printing to such a device.
60    
61    [2005-07-06]
62            Added ANSITerm structure, which provides support for ANSI terminal
63            display attributes (e.g., red text).
64    
65    [2005-07-06]
66            Refactored the pretty printing library.  The declarative way to
67            construct pretty-printing descriptions now sits on top of the
68            PP_STREAM interface.  Also removed "onNewline" function, which
69            was not implemented.
70    
71    [2005-05-05]
72            Added singleton function to MONO_PRIORITYQ interface.
73    
74    [2005-05-04]
75            Added the "join" combinator to ParserComb.
76    
77    [2005-03-21]
78            Fixed a bug in GetOpt.getOpt.  The argument processing functions
79            for ReqArg and OptArg, and the embedding function for ReturnInOrder
80            were getting applied to all arguments, even past a "--".
81    
82    [2005-02-11]
83            Added Atom.same and Atom.lexCompare to the Atom structure.  Eventually,
84            Atom.sameAtom will be removed.
85    
86    [2004-12-15]
87            Change HashString.hashString' to hashSubstring.
88    
89    [2004-12-09]
90            Added two simple statistics modules:
91            * RealOrderStats implements selection of arbitrary order
92              statistics as well as the median of an array of reals
93              in randomized linear time.
94            * UnivariateStats implements mean, variance, standard and average
95              deviation, skew, kurtosis, and median of a univariate sample
96              (i.e., a set of reals).
97    
98    [2004-11-29]
99            Added HashString.hashString' for substrings.
100            Hand-inlined CharVector.fold into HashString for efficiency.
101            Modified atom.sml so that Atom.atom' first tries to find an
102            existing atom before turning its argument into a string. [-blume]
103    
104    [2003-09-03]
105            Minor modifications to random.sml due to changes to some
106            Basis interfaces (slices).
107            Significant surgery on bit-array.sml to make it compile with
108            new signature MONO_ARRAY.  This will require further cleanup
109            in the future.
110    
111    [2003-08-28]
112            Made compilation of int-inf* conditional.  (The Basis now has
113            a spec-conforming implementation of IntInf, so the one here is
114            no longer needed.)  [-blume]
115    
116    [2003-07-31]
117            Added getDevice function to PP_STREAM signature.
118    
119    [2003-05-27]
120            Avoid poly-eq in Util/parser-comb.sml.
121    
122    [2003-05-22]
123            More cleanup (all in the name of eliminating incomplete matches):
124              - in HTML/html-attrs-fn.sml: fill in missing patterns in two
125                case expressions
126              - in HTML/html-gram: rewrote function groupDefListContents
127                to avoid the (unnecessary) incomplete match
128              - in PP/devices/html-dev.sml: made the implementation of popStyle
129                agree with the comment above it (popStyle on an empty
130                stack is supposed to be a nop)
131              - in PP/src/pp-stream-fn.sml: function setSize: handle case of
132                an empty scanStk
133              - in Util/prime-sizes.sml: raise Fail exceptions instead of
134                Match exceptions when reaching the end of a list
135                (Perhaps this should eventually be rewritten using an on-demand
136                 prime-number generator that kicks when needed.)
137    
138    [2003-05-22]
139            Cleanup logic in Scan.scanf function.
140    
141    [2002-10-03]
142            Fixed bug in formating reals with the %g format.
143    
144    [2002-06-18]
145            Fixed a bug in MatchTree.nth (regexp library).  Thanks to
146            Sami Nopanen.
147    
148    [2002-05-20]
149            Fixed bug in IntInf module: scanning of hex literals was not
150            handling "0x" prefixes.
151    
152    [2002-05-20]
153            Added ControlUtil module and stringControls function.
154    
155    [2002-05-17]
156            Added tyName field to ValueSyntax exception in Controls module
157            and path field to registry tree in ControlRegistry module.
158    
159    [2002-05-17]
160            Added == and != operators to INT_INF interface.  These are a
161            placeholder until IntInf moves into the SML/NJ compiler.
162    
163    [2002-05-16]
164            Added mergeWith function to ORD_MAP interface.
165    
166    [2002-05-15]
167            Revised Controls library.
168    
169    [2002-04-17]
170            Added Matthias Blume's implementation of Danvey-style format
171            combinators to the Util library.
172    
173    [2002-03-14]
174            Merged in Matthias Blume's Controls library.  Warning: the API
175            to this library is likely to change as we get some experience
176            with it.
177    
178    [2002-03-11]
179            Added consR1 .. consR5 functions to HashCons library.  These
180            can be used to hash-cons record types.
181    
182    [2002-02-21]
183            Fixed infinite loop in LeftPriorityQFn.fromList when given a
184            singleton list as input (Chris Okasaki provided the fix).
185    
186    [2002-02-12]
187            Added implementation of priority queues to Util library (using
188            Okasaki's leftist-tree implementation).
189    
190    [2001-10-19]
191            Added new HashCons library.
192    
193    [2001-10-19]
194            Added PrimeSizes module to Util library.
195    
196    [2001-09-27]
197            Fixed bug in UnixEnv module (reported by Leunga).
198    
199    [2001-05-05]
200            Added addrToString function to SockUtil module in INet library.
201    
202    [2001-05-04]
203            Modified GraphSCC module to support a list of roots (Blume).
204            The old interface still works, but will be dropped when we move
205            to the new Util library.
206    
207    [2001-04-06]
208            Added partition function to ORD_SET interface.
209    
210    [2001-04-05]
211            Added hasProps function to PropList module.
212    
213    [2001-03-16]
214            Minor bug fix in GetOpt: don't pad the help string, since it causes
215            line wraps when one of the help lines is longer than the screen
216            width.  It was also unneccesary.
217    
218    [2001-02-23]
219            Added inDomain function to the various kinds of hash tables.
220    
221    [2001-02-22]
222            Fixed bug in {Int,Word}RedBlackMapFn.insert (bug 1591).
223    
224    [2000-12-13]
225            Added the bit operations to the IntInf module (Leung).
226    
227    [2000-11-17]
228            Added where clause to GraphSCCFn result signature (Blume).
229    
230    [2000-10-20]
231            Made the result signature of the RegExpFn functor be opaque.
232    
233    [2000-09-28]
234            SML/NJ 110.0.7 release.
235    
236    [2000-09-02]
237            Added Word versions of hash tables (WordHashTable), finite
238            maps (WordRedBlackMap), and sets (WordRedBlackSet).
239    
240    [2000-09-02]
241            fixed bug in Format module (infinity caused infinite loop).
242    
243    [2000-07-19]
244            added anchored paths in CM files for NEW_CM.
245    
246    [2000-06-30]
247            added implementation of LWORD in Format module.
248    
249    [2000-05-16]
250            Fixed bug in dfa-engine.sml (bug number 1559).
251    
252    [2000-05-08]
253            Added setFn to PList.newProp return type.
254    
255    [2000-05-05]
256            Added sameHolder function to PropList module.
257    
258    [2000-04-05]
259            Fixed a bug in the filter/filteri hash table functions: the number
260            of items in the table was not being recomputed.
261    
262    [2000-04-04]
263            Added modify and modifyi iterators to hash tables.
264    
265    [2000-03-28]
266            Added anchorLink style to HTMLDev structure in PP/devices.
267    
268    [1999-12-03]
269            Added IntHashTable structure to Util library; this structure is
270            a specialization of hash tables to integer keys.
271    
272    [1999-12-03]
273            Added default cases to avoid "match not exhaustive" warnings.
274    
275    [1999-12-03]
276            Added GraphSCCFn functor to Util library, which implements a
277            strongly-connected components algorithm on directed graphs (written
278            by Matthias Blume).
279    
280    [1999-11-10]
281            Fixed a benign type error in RegExp/BackEnd/fsm.sml that was exposed by
282            the previous change.
283    
284    [1999-11-7]
285            Made the result signatures of ListSetFn and ListMapFn opaque.
286    
287    [1999-11-1]
288            Fixed bug in PP/devices/sources.cm under new CM (missing smlnj-lib.cm).
289    
290    [1999-10-20]
291            Fixed bug in RedBlack trees (the linear time construction of
292            trees from ordered sequences was producing backwards trees).
293    
294    [1999-10-18]
295            Changed UREF signature so that union, unify, and link operations
296            now return a boolean.
297    
298    [1999-10-18]
299            Added peekFn to PropList.newProp return result.
300    
301    [1999-10-14]
302            Added TextIOPP structure to pp-lib.cm (it was not being exported).
303    
304    [1999-09-21]
305            Changed the getOpt API.  Errors are now reported using a callback
306            and both usage and getOpt take records as arguments.  Also changed
307            the NoArg descriptor to take a function so that imperative argument
308            processing can be supported.
309    
310    [1999-09-20]
311            Changed CM files to be compatible with both the old (110.0.x) and
312            new (110.20+) versions of CM.
313    
314    [1999-09-17]
315            Added PropList:PROP_LIST structure.  This structure implements
316            property lists using Stephen Weeks's technique.
317    
318    [1999-09-17]
319            Improved the red-black tree implementations with linear-time union,
320            intersection, difference, and filter operations.  Also reimplemented
321            the delete function in a way that does not require an extra constructor.
322    
323    [1999-09-09]
324            Added Red-Black-Tree implementation of sets and maps.  Two new
325            functors (RedBlackMapFn and RedBlackSetFn) and four new structures
326            (IntRedBlackMap, IntRedBlackSet, AtomIntRedBlackMap, and IntRedBlackSet).
327            Also added aliases AtomMap and AtomSet that for the RB implementations.
328    
329    [1999-09-03]
330            Added missing support for WORD and WORD8 format items to Format structure.
331            Still need to handle LWORD items!!
332    
333    [1999-08-17]
334            Added DynamicArray:DYNAMIC_ARRAY structure.
335    
336    [1999-07-06]
337            Added declarative representation of pretty-printing to PPStreamFn.
338            This replaces the PPDescFn and PP_DESC components (which were not
339            implemented anyway).
340    
341    [1999-07-02]
342            Moved SockUtil structure into a new INet library.  Also split out the
343            Unix-specific socket operations into a UnixSockUtil module.  (Sockets
344            are now supported on Win32).
345    
346    [1999-06-17]
347            Added listKeys function to ORD_MAP API.
348    
349    [1999-06-14]
350            Added Riccardo Pucella's GetOpt structure to Util library.
351    
352    [1999-06-14]
353            Added singleton and inDomain functions to ORD_MAP API.
354    
355    [1999-06-02]
356            Merged in some bug fixes from the compiler's version of the IntInf
357            structure.
358    
359    [1999-05-05]
360            Fixed a couple of bugs in the PP library having to do with nesting
361            absolute and relative indentations.
362    
363    [1999-04-21]
364            Added a way to pass control information to a PP device via the PP
365            stream (function control in PP_STREAM).
366    
367    [1999-04-16]
368            Added better style support to the HTML PP device.
369    
370    [1998-09-04]
371            Added isEmpty predicate and first fucntion to ORD_MAP
372            signature (and to implementations).
373    
374    [1998-06-23]
375            Fixed a bug in ParserComb.bind (reported by Andrew Kennedy).
376    
377    --------------------------------------------------------------------------------
378    [1998-04-15] 110 --> 110.5
379    --------------------------
380    
381    There is now a regular expression library (mostly implemented by Riccardo
382    Pucella).  The implementation separates front-ends (which specify the
383    syntax of REs) from back-ends (which implement the matching algorithms).
384    Currently, we support AWK syntax as the only front-end and two different
385    back-ends.
386    
387    Added an implementation of the SML/NJ PP API to the pretty-printer examples.
388    
389    Fixed a bug in the IntInf structure with scanning strings of the form "1+2".
390    Also did some clean-up of the code.
391    
392    
393    --------------------------------------------------------------------------------
394    [1997-12-07] 109.32 --> 110
395    ---------------------------
396    
397    Added the function add' to the ORD_SET signature and the function insert'
398    to the ORD_MAP signature.  These functions fit the pattern of the fold
399    functions. (110 patch 3)
400    
401    Added the IntInf:INT_INF structure to the Util library.  This is a subset
402    of the optional IntInf structure defined by the SML'97 basis.
403    
404    Changed the Rand structure to use words as seeds and results.  This also
405    fixes bug 1047. (110 patch 3)
406    
407    Added a clear operation to the Queue and various hash table structures.
408    
409    Changed the ListFormat.formatList to ListFormat.fmt and ListFormat.scanList
410    to ListFormat.scan.  Added the function ListFormat.listToString.
411    
412    Updated the HTML library to the final 3.2 specification.  This involved adding
413    a new BODY element type (with attributes).  Also, removed the header/footer
414    arguments to the pretty-printer (they were a gross hack).
415    
416    Added PathUtil structure to Util library.  This is a more general version
417    of the old UnixPath module.
418    
419    
420    --------------------------------------------------------------------------------
421    [1997-10-01] 109.31 --> 109.32
422    ------------------------------
423    
424    Changed the type of the exec instruction in the Reactive library.
425    
426    
427  --------------------------------------------------------------------------------  --------------------------------------------------------------------------------
