19    Description:
20    
21    Made some minor modifications to elabcore.sml to have source regions
22    be propagated more tightly -- resulting in better (i.e., smaller)
23    regions being reported in error- and debug messages.

28    Tag: blume-20041008-cmkw
29    Description:
30    
31    Fixed handling of keywords in .cm files: After seeing "is" the lexer
32    treats subsequent occurrences of "group", "library", "source", "is",
33    "*", and "-" as ordinary identifiers rather than keywords.
34    
35    Most seriously, this fixes a problem with CM's "shell" tool.  The tool
36    is supposed to accept a tool argument called "source", but this did
37    not work because of the clash with the keyword.

43    Description:
44    
45    Assorted cleanup work:
46    
47      - got rid of intstrmap in favor of using the library's
48        hash table implementation
49      - threw out most of the pathnames stuff, as it was not used anyway
50      - simplified tokentable implementation
51      - fixed some minor spelling errors

56    Tag: blume-20041006-handler
57    Description:
58    
59    Cleaned up the absyn to reflect the invariant that HANDLE always
60    carries a FNexp as part of the type definition.  This eliminates some
61    superfluous sanity checks at runtime down the road.
62    
63    Some minor cleanup of the btrace code.

69    Description:
70    
71    Added hack to make slave mode work in the presence of the version
72    tool.  (Still, since the master does two passes over the code for
73    CMB.make, the release number gets bumped twice when slaves are
74    attached.  I don't know if this is worth fixing...)

79    Tag: blume-20040930-version
80    Description:
81    
82    * Moved the "version" magic into its own little library under
83    src/system/smlnj/internal.  This avoids expensive reconstruction
84    of a stable src/compiler/core.cm.
85    
86    * At the same time, structure CompilerVersion is now known as structure
87    SMLNJVersion.
88    
89    * Arranged for the version tool to NOT kick in when rebuilding the system
90      (makeml -rebuild, fixpt).  Otherwise one would never reach a fixpoint.
91      Also, loading the versiontool does not work when rebuilding the system
92      because CM is not properly initialized at that time.

97    Tag: blume-20040929-autoversion
98    Description:
99    
100    Implemented some CM magic to have
101        file src/compiler/TopLevel/main/version.sml
102    generated automagically.
103    The version is taken from two files: config/version and config/release.
104    The first is expected to contain a two-part version number such as 110.49.
105    The second should contain a single number, but it may be missing.
106    
107    If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
108    time the version tool is loaded (which is the first time you say CMB.make),
109    then the tool will increment the value stored in config/release every
110    time CMB.make is invoked.
111    
112    The binfile format is now insensitive to anything beyond the first
113    two components of a version number, so bumping the release does not render
114    binfiles incompatible.  Auto-bumping can be used to keep track of versions
115    during development without invalidating existing binfiles.
116    
117    In any case, every CMB.make updates the date information in version.sml.
118    (This is the date that is printed in the banner.)

124    Description:
125    
126    Some cleanup of the controls code.

131    Tag: blume-20040927-controls
132    Description:
133    
134    Added two pieces of functionality to the Controls interface:
135    
136    1.   val save'restore: 'a control -> unit -> unit
137    
138       grabs the current value of the control in stage 1 and restores it
139       in stage 2.
140    
141    2.   val set' : 'a control * 'a -> unit -> unit
142    
143       stores the given value into the control in stage 2 (i.e., delayed)
144       but does all error checking in stage 1.
145       (This is for string controls that need to do parse their argument --
146        something that might fail.  In some cases, notably in CM, one
147        already knows the intended argument but wants to delay the actual
148        assignment until a time when error recovery would be more difficult.)
149    
150    Changed the handling of controls in tool arguments to classes "sml" and
151    "lazysml":
152       - use Controls.save'restore as a more robust way of restoring the
153         old value (in particular: without having to re-parse the string)
154       - use controls to handle the "overload" keyword in the init group
155         (I believe this change actually fixes a long-standing obscure bug.)
156

160    Tag: blume-20040927-lazysml
161    Description:
162    
163    Added a new tool class called "lazysml" to CM's tool chest.  The only
164    difference to "sml" is that compilation is done with Control.lazysml
165    set to true.  A source of class "lazysml" is automatically recognized
166    by a file name suffix of ".lml".
167    
168    In addition to the above feature, the original class "sml" now also
169    supports a tool argument "lazy" which has the same effect.  As a
170    result, the following three lines are equivalent:
171    
172        foo.sml : lazysml
173        foo.sml : sml (lazy)
174        foo.sml (lazy)
175    
176    The setting goes into effect both during parsing and during
177    compilation.  The original setting is restored right after parsing and
178    after compilation, respectively.
179    
180    In addition to all the above, there is also a general mechanism to set
181    ANY of the "controls" that are available at the command line via
182    "-C..." on a per-sml-file basis.  The same rules that apply for "lazy"
183    apply as well. (In fact, "lazy" is implemented as a special case of
184    the general mechanism.)
185    
186    The .cm file syntax uses a new keyword tool argument called "with".
187    There are several ways of indicating the desired settings:
188    
189        foo.sml (with:parser.quotations=true)
190        foo.sml (with:(name:parser.quotations value:true))
191        foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
192        foo.sml (with:(name1=value1 name2=value2 ...))
193        foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
194    
195        etc.
196    
197    Another possible abbreviation is to leave out the =v or value:v part
198    if the name refers to a boolean control (in which case the value is
199    taken to be true).  Thus, one could get lazy sml also by saying:
200    
201        foo.sml (with:parser.lazy-keyword=true)
202        foo.sml (with:parser.lazy-keyword)
203        foo.sml (with:(name:parser.lazy-keyword value:true))
204        foo.sml (with:(name:parser.lazy-keyword))

210    Description:
211    
212    Turned message about "emiting long form of branch" off by default.
213    Added a control flag to turn it back on when desired.

222    Melissa O'Neill for providing the code!

227    Tag: blume-20040923-envvars
228    Description:
229    
230    1. Changed definition of type ControlRegistry.registry_tree to
231       include control_info (i.e., the name of the controlling environment
232       variable).
233    
234    2. Added command-line flags -e and -E to print the names of environment
235       variables that can be used to control internal settings.
236       (This uses the new API mentioned in 1.)
