1 : jhr 3992 Standard ML of New Jersey Change Log
2 :     ====================================
3 :     The Fellowship of SML/NJ
4 : jhr 3998 {version}, {releasedate}:
5 : jhr 3992
6 : jhr 4002 This file documents changes to the Standard ML of New Jersey system since
7 :     March of 2000 (around Version 110.26). The change log primarily covers
8 :     the compiler, the compilation manager (*CM*), the *MLRISC* library, and
9 :     the runtime system. There are occasional entries about other components
10 :     (_e.g._, the *SML/NJ Library* and *ML-LPT*), but these components have
11 :     their own change logs that should be consulted.
12 :    
13 : jhr 3992 //////////////////////////////////////////////////////////////////////
14 :     This change log is in ASCII doc format. An HTML version of the
15 :     change log can be generated using the command
16 :    
17 : jhr 4049 make html
18 : jhr 3992
19 :     An entry should be made for _every_ commit to the repository.
20 :     The entries in this file will be used when creating the README
21 :     for new versions, so keep that in mind when writing the
22 :     description.
23 :    
24 :     The structure of the HISTORY is that there is a section for
25 :     each release, which starts with a section header of the form
26 :    
27 :     == Version xxx.yy; yyyy/mm/dd
28 :    
29 :     The content of a section is a list of entries. The form of an
30 :     entry should be:
31 :    
32 :     [yyy/mm/dd]::
33 :     +
34 : jhr 3995 Description ...
35 : jhr 3992 +
36 :     owner:[Your Name,URL]
37 :    
38 : jhr 3995 Note that we put "+" at the beginning of blank lines. Entries are items
39 :     in a labeled list and the "+" character keeps eveything in the same list
40 :     element.
41 :    
42 : jhr 3992 Here is a quick asciidoc cheat sheet:
43 :    
44 :     + new paragraph
45 :     *foo* bold "foo"
46 :     _foo_ italic "foo"
47 :     +foo+ teletype "foo"
48 :     http:/some.website.org/path[] URL
49 :     bugref:[123] displays as "#123" with
50 :     a link to the bug report.
51 : jhr 4134 reqref:[123] displays as "#123" with a
52 :     link to the feature request.
53 : jhr 3992 owner:[name,url] displays name with URL link.
54 :    
55 : jhr 3995 Sub lists should be bracketed with lines containing just "--".
56 : jhr 3992 Bulleted list items start with a single dash or one to five
57 :     asterisks followed by some white space then some text. Numberd
58 :     list items begin one to five period characters, followed by
59 :     some white space then the item text.
60 :    
61 : jhr 3995 Literal (verbatim) blocks are delimited by
62 :     .....................
63 :     stuff
64 :     .....................
65 :    
66 : jhr 3992 Superscripts and subscripts are denoted by putting ^ (or ~)
67 :     around the text to superscripted (superscripted). For example,
68 :     the number 256 can be written as 2^8^.
69 :    
70 :     SML source code displays can be included as source blocks:
71 :    
72 :     [source,sml]
73 :     ------------
74 :     structure Foo = struct val x = 1 end
75 :     ------------
76 :    
77 :     Source code will be stylized using the pygmentize (http://pygments.org)
78 :     tool.
79 :    
80 :     More information about asciidoc can be found at http://asciidoc.org.
81 :    
82 : jhr 4002 NOTE: the original HISTORY file was converted to ASCIIDOC using a Perl
83 :     script. This script gets the basic structure for entries correct,
84 :     but there still needs to be a fair bit of editing to add ASCIIDOC
85 :     markup, fix indentation issues, nested lists, etc. Working from most
86 :     recent to oldest, I've edited back to release 110.46 (2004/06/17).

91 :     // == Recent updates
92 : jhr 3992
93 : jhr 4204 //--------------------------------------------------------------------
94 :     [2015/11/09]::
95 :     +
96 :     Fixed bug bugref:[147] (Hexadecimal escapes in strings are not supported).
97 :     We previously did not support Unicode escapes in string literals. We now
98 :     do so, with non-ascii codepoints being mapped to the UTF-8 encoding.

101 :    
102 :     //--------------------------------------------------------------------
103 :     [2015/10/28]::
104 :     +
105 :     Partial fix for the noisy exception-stack traces on the +Error+ exception.
106 :     The cases that are handled by this change are applying +use+ to a non-existent
107 :     file and when there are compilation errors in a program being built by
108 :     +CM.make+. What remains to be handled is the situation where +CM.make+ is
109 :     applied to a non-existent file.

115 : jhr 4126
116 : jhr 4060 //--------------------------------------------------------------------
117 : jhr 4157 [2015/10/04]::
118 :     +
119 :     Patched +base/compiler/FLINT/clos/closure.sml+ so that *Twelf* will
120 : jhr 4204 build again. Fixes bug bugref:[140] (Lookup failure in +closure.sml+
121 :     when compiling *Twelf*).

124 :    
125 :     //--------------------------------------------------------------------
126 : jhr 4141 [2015/09/28]::
127 :     +
128 : jhr 4151 Added support for a *Successor ML* tool to CM. This tool allows one
129 :     to specify that a source file +fool.sml+ is *Successor ML* source code in the
130 :     following ways:
131 :     +
132 :     --------
133 :     foo.sml : succ-ml
134 :     foo.sml : sml (succ-ml)
135 :     foo.sml (succ-ml)
136 :     --------

138 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
139 :    
140 :     //--------------------------------------------------------------------
141 :     [2015/09/28]::
142 :     +
143 : jhr 4147 Added the directory +base/old-basis+ to support backward-compatible
144 :     views of the *Basis Library*. You can use these by replacing the
145 :     line
146 :     +
147 :     --------
148 :     $/basis.cm
149 :     --------
150 :     +
151 :     with
152 :     +
153 :     --------
154 :     $/basis-2004.cm
155 :     --------
156 :     +
157 :     in your CM files.
158 :    
159 :     //--------------------------------------------------------------------
160 :     [2015/09/28]::
161 :     +
162 : jhr 4141 New implementation of +Date+ structure in the Basis, which fixes bugs
163 : jhr 4204 bugref:[138] (Incorrect behavior for +Date.fromTimeLocal+) and
164 :     bugref:[139] (+Date.date+ is broken). Note that some more thought should
165 : jhr 4141 be given to the correct semantics of +Date.date+ when dealing with
166 :     offsets. For example, should an offset of +23 hours produce the same
167 :     date as an offset of -1 hours? Currently our implementation produces
168 :     different results (by a day) for these two situations.
169 :     +
170 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]
171 :    
172 :     //--------------------------------------------------------------------
173 : jhr 4126 [2015/09/25]::
174 :     +
175 : jhr 4134 Implemented the changes for
176 :     https://github.com/SMLFamily/BasisLibrary/wiki/2015-003-Additional-operations-on-sequences[
177 : jhr 4147 Basis Library Proposal 2015-003]. This proposal added operations to
178 : jhr 4134 the following signatures:
179 :     +
180 :     [source,sml]
181 :     ------------
182 :     signature ARRAY
183 :     signature LIST
184 :     signature LIST_PAIR
185 :     signature MONO_ARRAY
186 :     signature MONO_VECTOR
187 :     signature OPTION
188 :     signature STRING
189 :     signature TEXT
190 :     signature VECTOR
191 :     ------------
192 :     +
193 :     and the following structures:
194 :     +
195 :     [source,sml]
196 :     ------------
197 :     structure Array : ARRAY
198 :     structure CharArray : MONO_ARRAY
199 :     structure CharVector : MONO_VECTOR
200 :     structure List : LIST
201 :     structure ListPair : LIST_PAIR
202 :     structure Option : OPTION
203 :     structure Real64Array : MONO_ARRAY
204 :     structure Real64Vector : MONO_VECTOR
205 :     structure String : STRING
206 :     structure Text : TEXT
207 :     structure Vector : VECTOR
208 :     structure Word8Array : MONO_ARRAY
209 :     structure Word8Vector : MONO_VECTOR
210 :     ------------
211 :     +
212 :     While it is very unlikely that these changes will break existing code, there are
213 : jhr 4139 a a couple scenarios in which the code might break. Namely, when use of +open+
214 :     introduces conflicts and when user code implements one of the affected Basis Library
215 :     signatures. Both of these examples occurred in the *SML/NJ* source code; the former
216 :     in the *ml-yacc* sources and the latter in the *MLRISC* sources.

220 :     //--------------------------------------------------------------------
221 :     [2015/09/25]::
222 :     +
223 :     Added the optional implementations of +PackReal64Big+ and +PackReal64Little+.
224 : jhr 4126 This addition addresses feature request reqref:[82]
225 :     (Implementations of +PACK_REAL+ missing). The implementation
226 :     uses the approach suggested by
227 :     https://github.com/msullivan/sml-util/blob/master/libs/pack-real.sml[Michael Sullivan].

233 :     +
234 :     Fixed bug bugref:[45] (Compiler bug in specialize phase). This bug
235 :     was in +compiler/FLINT/opt/fcontract.sml+ and was the result of a bad
236 :     interaction between eta contraction and inlining. As part of the fix,
237 :     I cleaned up the code in this part of FLINT a bit.

281 : jhr 4086 [2015/07/23]::

288 : jhr 4076 [2015/07/08]::
289 :     +
290 : jhr 4077 Added Linux 4.* kernels to the list of operating systems recognized
291 :     by the ++.arch-n-opsys++ script (fixes bug bugref:[134]).
292 : jhr 4076 +
293 :     owner:[John Reppy,http://cs.uchicago.edu/~jhr]

295 :     //--------------------------------------------------------------------
296 : jhr 4074 [2015/06/11]::
297 :     +
298 :     Added Mac OS X 10.11 (El Capitan) to the list of operating systems
299 :     recognized by the ++.arch-n-opsys++ script.

303 :     //--------------------------------------------------------------------
304 : jhr 4060 [2015/05/27]::
305 :     +
306 : jhr 4105 Added support for *Successor ML* lexical extensions. These can be enabled
307 : jhr 4107 using the command-line option ++-Cparser.succ-ml=true++ or by the assignment
308 : jhr 4062 +
309 :     [source,sml]
310 :     ------------
311 :     Control.succML := true;
312 :     ------------
313 :     +
314 :     at the REPL. The extensions are as follows:
315 : jhr 4105 +
316 : jhr 4060 --
317 : jhr 4105 - Underscore ("++_++") as a separator in numeric literals; __e.g.__, ++123_456++,
318 :     ++0wxff_ff_ff_f3++, ++123_456.1++, ...
319 : jhr 4060
320 :     - end-of-line comments, which are denoted using ++(*)++. End-of-line comments
321 :     properly nest into conventional block comments. For example, the following
322 :     block comment is well formed:
323 :     +
324 :     [source,sml]
325 :     ------------
326 :     (*
327 :     fun f x = x (*) my identity function *)
328 :     *)
329 :     ------------
330 :     +
331 : jhr 4062 - binary literals for both integers and words; __e.g.__, ++0b0101_1110++, or
332 : jhr 4060 ++0wb1101++.
333 :     --
334 : jhr 4105 +
335 :     This change is the beginning of a program to add *Successor ML* feature to *SML/NJ*;
336 :     See https://github.com/SMLFamily/Proposed-Definition-of-Successor-ML[] for more
337 :     details.

344 : jhr 3992 //--------------------------------------------------------------------
345 : dbm 4001 [2014/12/19]::
346 :     +
347 :     Major revision of the machinery for overloading resolution for both
348 :     operators (vars) and literals, now using a common mechanism. This fixes
349 :     bug bugref:[52] by improving the error message when an overloaded
350 : jhr 4049 operator is inconsistent with its context. Updated 23 files, including
351 : dbm 4001 major changes in +overload.sml+, +types.sml+, +unify.sml+, +elabcore.sml+,
352 :     +typesutil.sml+. The overload declaration is still used in
353 :     +pervasives.sml+, where the order of the specified instances of an
354 : jhr 4002 ordering determines the default interpretation (_i.e._, the first one).
355 : dbm 4001 +
356 :     The +SCHEME+ and +LITERAL+ forms of tyvars are replaced by a new
357 :     +OVLD+ form that tracks potential instantiations of the type of the
358 :     overloaded vars or literals.

364 :     +
365 :     Moved +base/NOTES/HISTORY+ file to +doc/src/changelog/HISTORY.txt+
366 :     and converted it to http://asciidoc.org[ASCIIDOC] format. Have also
367 :     moved the +README+ files from +base/READMES+ to +doc/src/release-notes+.

375 :     +
376 : jhr 4002 Preliminary cleanups before changes to overloading
377 :     +
378 : jhr 3994 Minor cleanup in +Elaborator/elaborate/elabcore+ (function +elabOVERLOADdec+)
379 :     and in +ElabData/types/typesutil.sml+ (function +matchScheme+). Preparing for
380 :     a new method of handling type checking of overloaded operators. [Note
381 :     that there is no reason for the options field of +OVLDvar+ to be a
382 :     reference -- it is never updated. Changing this requires corresponding
383 :     change in pickling.]
384 :     +
385 :     Also added an +etopdebugging+ flag (+ElabControl+) for debugging in
386 :     +elabtop.sml+. Modified ++elabcontrol.++{++sml++,++sig++} and
387 :     +elabtop.sml+. Also rearranged ast and absyn printing in +evalloop.sml+.

400 :     [2014/10/11]::
401 :     +
402 :     Added +-D_FILE_OFFSET_BITS=64+ flag to +x86-linux+ makefile. This flag
403 :     is necessary to avoid spurious +EOVERFLOW+ errors on some versions of
404 :     Linux. The problem appears to be limited to large file systems that
405 :     have more than 2^32^ inodes.

1396 :     +
1397 :     Fixed some bugs in new Div code in +FLINT/trans/translate.sml+.
1398 :     +
1399 :     Also, changed the handling of "no core access": When +translate.sml+
1400 :     needs access to a core exception at a time when the core has not
1401 :     been set up yet (this only happens when compiling +system/smlnj/init/+*),
1402 :     then don't bother generating the corresponding tests.
1403 :     +
1404 :     The old scheme was to generate a bogus value to be used in place of
1405 :     the exception. Unfortunately, that confuses the plambda type checker.
1406 :     Moreover, it does not do any good, because at runtime we don't expect
1407 :     such an exception to be ever raised. (The code in +system/smlnj/init/+*
1408 :     has to be written very carefully with this in mind!)

1449 :     [2007/05/23]::
1450 :     +
1451 :     CMB (and CM) now automatically defines the CM "preprocessor" symbol
1452 :     NO_PLUGINS during "makeml -rebuild" or when CM operates in "slave" mode.
1453 :     +
1454 :     (In addition, CMB_REBUILD_MODE is defined for +makeml -rebuild+,
1455 :     CM_SLAVE_MODE is defined in attached slaves while running CM.make
1456 :     or CM.rebuild, and CMB_SLAVE_MODE is defined in attached slaves
1457 :     while running +CMB.make+. The point is that the single symbol
1458 :     NO_PLUGINS is definde in all three cases.)
1459 :     +
1460 :     I changed the three locations within the sources that get compiled
1461 :     during +CMB.make+ where *ml-yacc* or *ml-lex* input is processed: When
1462 :     NO_PLUGINS defined, then the use of the mlyacc and mllex tools
1463 :     is bypassed.
1464 :     +
1465 :     When bootstrapping new versions of the compiler, there can be
1466 :     situations where the plugin tools for *ml-yacc* and *ml-lex* (or *ml-ulex*)
1467 :     are not available or otherwise not operational. In this case one can
1468 :     manually define the NO_PLUGINS symbol prior to running +CMB.make()+. To
1469 :     do so, the following command should be issued at the interactive
1470 :     prompt:
1471 :     +
1472 :     [source,sml]
1473 :     ------------
1474 :     #set (CMB.symval "NO_PLUGINS") (SOME 1);
1475 :     ------------
1476 :     +
1477 :     A +CMB.make+ with NO_PLUGINS defined relies on the existence of the
1478 :     files that normally would be generated by *ml-yacc* and *ml-lex*.
1479 :     (Copies of these files are in the repository.)

1499 :     just libaries and now get installed like ordinary libaries.
1500 :     +
1501 :     There are now a number of new installation targets that give some
1502 :     fine-grain control over what classes and suffixes are known, and what
1503 :     they will map to.
1504 :     See +config/targets+ for details.
1505 :     +

1516 :     name: CM_TOLERATE_TOOL_FAILURES). The default is false and makes
1517 :     CM fail if a shell tool reports a non-success exit status. If
1518 :     the control is set to true, then CM will press on after tool failures
1519 :     in the event that the target files exist (even though they are
1520 :     considered outdated). Turning the control to true can be useful for

1528 :     Merge of ml-lpt revisions for 110.64.
1529 :     +
1530 :     The name of several ml-lpt-lib modules has changed:
1531 :     +
1532 :     [grid="none",frame="none",width="50%",cols=">2,^1,<2"]
1533 :     |===============================================

1537 :     | +EBNF+ | => | +AntlrEBNF+
1538 :     |===============================================
1539 :     +
1540 :     The *ml-antlr* specification format has changed: declarations such as
1541 :     +%tokens+ and nonterminal definitions can occur *multiple* times in the
1542 :     same specification. The semantics are such that each new declaration
1543 :     extends the previous ones. This does not apply to +%start+ or +%name+,
1544 :     of course.
1545 :     +
1546 :     Importing a grammar via +%import+ now includes *all* declarations in from
1547 :     the imported grammar, except for +%name+, +%entry+, and +%start+. Tokens
1548 :     and nonterminals can be dropped using the new +%dropping+ clause of the
1549 :     +%import+ directive; the separate +%drop+ and +%extend+ have been removed.
1550 :     +
1551 :     We now allow optional type annotations on nonterminals, using the +%nonterms+
1552 :     directive as in *ml-yacc*.
1553 :     +
1554 :     The +refcell+ construct is now implemented using SML's regular reference
1555 :     cells, so the +:==+ and +!!+ notation has been deprecated.
1556 :     +
1557 :     The *ml-antlr* tool now does much more checking of specifications, and
1558 :     its error messages have been greatly improved. Error repair for
1559 :     generated parsers has been completely rewritten, and is now both
1560 :     much faster and more accurate.
1561 :     +
1562 :     *ml-ulex* is now more lenient with escape codes (non-SML-standard
1563 :     escape codes are now interpreted literally, so _e.g._, +\|+ denotes "+|+").
1564 :     Also, character classes may now include a "+-+" character at the beginning
1565 :     as is standard in most other regexp tools.
1566 :     +
1567 :     All of these changes are documented in the user guide, which has
1568 :     been updated and improved with this merge.

1587 :     +%tokens+ and nonterminal definitions can occur *multiple* times in the
1588 :     same specification. The semantics are such that each new declaration
1589 :     extends the previous ones. Grammar extension constructs have also
1590 :     changed. We now allow type annotations on nonterminals. Finally,
1591 :     the refcell construct is now implemented using SML's regular reference
1592 :     cells, so the +:==+ and +!!+ notation has been deprecated. All of these
1593 :     changes will appear in the 110.64 user guide for *ml-lpt*.
1594 :     +
1595 :     The *ml-antlr* tool now does much more checking of specifications, and
1596 :     its error messages have been greatly improved. There has also been
1597 :     some work on the error repair process for generated parsers, but this

1754 :     Brought ml-lpt manual up-to-date with the code. Many minor
1755 :     improvements to the tools, and a few minor bugfixes. Prepared
1756 :     ml-lpt-lib for integration with new +UTF8+ structure. Changed
1757 :     the interface for creating streams in *ml-ulex* (we now support
1758 :     stream creation from several kinds of sources). Overall, the

1848 :     [2006/12/08]::
1849 :     +
1850 :     Added code to CM's "standard shell tool" implementation which
1851 :     causes it to tolerate (with a warning) the situation where the shell
1852 :     command fails (_e.g._, due to the shell command's non-existence)
1853 :     as long as all target files exist.
1854 :     +
1855 :     This makes it possible to, _e.g._, build *ml-yacc* from sources even if
1856 :     svn checkout messed up the time stamps on files in such a way that
1857 :     +yacc.grm+ is younger than yacc.grm.sml or +yacc.grm.sig+. (*Ml-yacc*
1858 :     would be needed to re-process +yacc.grm+, but obviously it might not yet be
1859 :     available at that time.)

1938 :     +
1939 :     (All pathnames are relative to the SML/NJ "root" directory.)
1940 :     +
1941 :     In addition, there is also a new
1942 :     +
1943 :     ...........
1944 :     ml-lpt
1945 :     ...........
1946 :     +
1947 :     directory containing two new program generator tools: *ml-ulex* and
1948 :     *ml-antlr* (a lexer generator that handles unicode and an ANTRL-inspired
1949 :     LL(k) parser generator). These tools are currently "beta-quality"
1950 :     +
1951 :     The latest versios of the sources can now be obtained anonymously
1952 :     via subversion. For this, it is useful to first check out
1953 :     +
1954 :     ...........
1955 :     svn://smlnj-gforge.cs.uchicago.edu/smlnj/admin
1956 :     ...........
1957 :     +
1958 :     and put the resulting directory on your shell's PATH. This provides
1959 :     access to three shell scripts: checkout-all.sh, stat-all.sh,
1960 :     and refresh-all.sh.
1961 :     +
1962 :     To create a freshly checked-out copy of the sources, do
1963 :     +
1964 :     ...........
1965 :     checkout-all.sh [dir]
1966 :     ...........
1967 :     +
1968 :     where dir is the optional SML/NJ root directory (default is ".").
1969 :     +
1970 :     This creates the above directory layout. Each subdirectory of
1971 :     the root is under individual subversion control. The stat-all.sh
1972 :     and refresh-al.sh scripts apply "svn stat" or "svn update" to
1973 :     each of these subtrees.

1976 :    
1977 :     //--------------------------------------------------------------------
1978 :     [2006/11/02]::
1979 :     +
1980 :     Reorganized directory layout.
1981 :     +
1982 :     This is a temporary solution, more reorganization is to come.
1983 :     +
1984 :     The basic idea is to have a number of toplevel trees, each corresponding
1985 :     to a well-defined part of the overall system. Each part can be
1986 :     maintained individually, even in separate source repositories,
1987 :     although currently we still serve everything out of the main
1988 :     smlnj-gforge tree.
1989 :     +
1990 :     Installer and and scripts have been updated to reflect the new
1991 :     layout. The installer (base/src/system/smlnj/installer) is now
1992 :     "scriptable" to avoid burning too much knowledge about the
1993 :     layout into SML source code. The main script used by the installer
1994 :     is in config/actions.
1995 :     +
1996 :     The main change is that many of the subdirectories of what used to
1997 :     be known as "src" have moved to the toplevel. The "src" directory
1998 :     itself has moved down into a subtree called "base". (We may eventually
1999 :     get rid of the extra level of indirection represented by "src".)
2000 :     +
2001 :     The layout is now as follows:
2002 :     +
2003 : jhr 4002 [frame="none",width="90%",cols="<2,<3",options="header"]

2029 :     In +$gf/admin+ there are a few useful shell scripts for checking out
2030 : jhr 3992 and maintaining the entire collection of trees:

2032 : jhr 4002 --
2033 :     +admin/checkout-all.sh+ [__dir__]::
2034 : jhr 3992 +
2035 : jhr 4002 optionally creates _dir_ and checks out all trees from their
2036 :     default repositories; if _dir_ is missing, checkout into the
2037 :     current working directory.
2038 :     +
2039 :     +admin/refresh-all.sh+ [__dir__]::
2040 :     looks at all trees (from the above list) in _dir_ (default: .)
2041 :     and runs "+svn update+" if the tree exists and is under
2042 :     subversion control;
2043 :     non-existing or non-subversion trees are skipped
2044 :     +
2045 :     +admin/stat-all.sh+ [__dir__]::
2046 :     like +refresh-all.sh+, but runs "+svn stat+" instead

2223 : jhr 4002 Enabling +$/html-lib.cm+ in +config/preloads+ did not work. This is fixed
2224 :     now. (Since the anchor mapping for +html-lib.cm+ is not yet in effect
2225 :     at the time when +config/preloads+ is processed, the library has to
2226 : jhr 3992 be referred to by another name. In 110.57 this would be
2227 : jhr 4002 +$SMLNJ-LIB/HTML/html-lib.cm+. I arranged for +$smlnj/smlnj-lib/html-lib.cm+
2228 : jhr 3992 to be valid as well.)

2270 :     +
2271 : jhr 4002 Reversed change to +src/system/smlnj/internals/versiontool.cm+. This
2272 : jhr 3992 file gets loaded as a tool -- by the equivalent of CM.make during the
2273 : jhr 4002 run of +CMB.make+. Thus, CMB's path configuration is meaningless for
2274 : jhr 3992 it. Instead, it has the status of "user code", so it should use
2275 : jhr 4002 +$/basis.cm+ to refer to the Basis library. (At least that's true for
2276 : jhr 3992 the purpose of bootstrapping the previous change. In the future it
2277 : jhr 4002 might make sense to have +versiontool.cm+ refer to
2278 :     +$smlnj/basis/basis.cm+, _i.e._, the version of the Basis that the
2279 : jhr 3992 compiler itself uses.)
2280 :     +
2281 : jhr 4002 Also patched +src/system/testml+ to have it activate those extra anchor
2282 :     bindings in +config/extrapathconfig+.

2287 :     [2005/11/15]::
2288 :     +
2289 :     This change affects the way the following libraries are tied into
2290 :     the system:
2291 :     +
2292 : jhr 4002 ....................
2293 : jhr 3992 $/basis.cm
2294 :     $/smlnj-lib.cm
2295 :     $/pp-lib.cm
2296 :     $/controls-lib.cm
2297 :     $/html-lib.cm
2298 :     $/ml-yacc-lib.cm
2299 : jhr 4002 ....................
2300 : jhr 3992 +
2301 :     These libraries are now internally (as seen from the source code
2302 :     of the implementation itself) known by the following names:
2303 :     +
2304 : jhr 4002 ....................
2305 : jhr 3992 $smlnj/basis/basis.cm
2306 :     $smlnj/smlnj-lib/smlnj-lib.cm

2310 :     $smlnj/ml-yacc/ml-yacc-lib.cm
2311 : jhr 4002 ....................
2312 : jhr 3992 +
2313 :     This makes it possible to work with code that requires different
2314 :     versions of these libraries, and which refers to these libraries using
2315 :     their "default" names (_i.e._, the first set of names above). In other
2316 :     words, one can un-define or re-define those default names without
2317 :     compromising the proper functioning of the compiler itself.
2318 :     +
2319 :     A similar procedure had already been performed for several of the
2320 : jhr 4002 *MLRISC* libraries that are linked into the compiler. I did some
2321 : jhr 3992 cleanup on this code.
2322 :     +
2323 :     A new file in the config directory (named extrapathconfig) is
2324 :     responsible for setting up path anchors that the compiler itself does
2325 :     not need, but that are typically required by user code.

2501 : jhr 3992 +
2502 : jhr 4002 This is much like +SMLofNJ.exportML+, but starting from the resulting

2505 : jhr 4002 +CM.redump_heap+ does not return but ends the interactive session.
2506 :     Thus, +CM.redump_heap+ is a lot like +SMLofNJ.exportFn+.
2507 : jhr 3992 +
2508 : jhr 4002 Internally, +redump_heap+ winds the dynamic execution context back to
2509 : jhr 3992 the point where the original heap image was created and re-executes

2619 : jhr 4002 To be able to test *heap2exec*, uncomment the request for "+heap2asm+" in

2621 :     from "heap2exec" mentioned below. Not a typo.)
2622 :     +
2623 :     To perform an actual test, run the command
2624 :     +
2625 :     $ bin/heap2exec heapfile execfile
2626 :     +
2627 : jhr 4002 (You can put *heap2exec* on your shell's path.)
2628 : jhr 3992 +
2629 :     For example, run
2630 :     +
2631 :     $ bin/heap2exec bin/.heap/ml-yacc.ppc-darwin mly
2632 :     +
2633 : jhr 4002 This will create a standalone executable called "+mly+" that you can
2634 : jhr 3992 then invoke directly as a command.

2851 : jhr 3992 32-bit wide.)

2853 : jhr 3995 Also started to add similar support for +Int64+, but major pieces of that

2860 :     +
2861 : jhr 3995 Structure +Word64+ is now (almost) complete, word literals and patterns
2862 : jhr 3992 seem to work. There are a few odd pieces missing. In particular,
2863 : jhr 3995 I didn't do the {++from++,++to++}++LargeWord++ parts because +LargeWord+
2864 :     is still +Word32+ at the moment.
2865 : jhr 3992 +
2866 : jhr 3995 Making +Word64+ official would mean that +LargeWord+ becomes +Word64+. But
2867 : jhr 3992 this requires extreme care because most word-word conversions have to
2868 : jhr 3995 go through +LargeWord+, so making a mistake means loss of efficiency or
2869 : jhr 3992 worse. Eventually there will be a solution similar to (but actually
2870 : jhr 3995 simpler than) what I did with +IntInf+.

2944 :     Added a mechanism for getting back-trace information from standalone
2945 :     programs. Here is how it works:
2946 :     +
2947 : jhr 4002 --
2948 :     . The part of the program from which you want to get backtrace
2949 :     information (usually the whole program) should be wrapped with
2950 :     BackTrace.monitor. This is a +(unit->'a)->'a+ function, and your
2951 :     main program could be modified from something like
2952 : jhr 3992 +
2953 : jhr 4002 [source,sml]
2954 :     ------------
2955 :     fun main (pgm, args) = ...

2963 :     ------------
2964 : jhr 3992 +
2965 : jhr 4002 . To be able to access +BackTrace.monitor+, you have to add the
2966 :     library +$smlnj-tdp/plugins.cm+ to the +.cm+ file that contains your
2967 :     main function.
2968 : jhr 3992 +
2969 : jhr 4002 . Remove all compiled code (_i.e._, all the .cm/ subdirectories that

3026 :     To get the benefits of any of these plugin modules, the code in
3027 : jhr 4002 question must be compiled with TDP instrumentation turned on. This
3028 :     can be done by setting +SMLofNJ.Internals.TDP.mode+ to +true+.
3029 :     (The ref cell is also controlled via the +-Ctdp.instrument=...+ switch.)

3031 :     Plugins are selected at link time. (Pre-compiled instrumented code
3032 :     can be re-loaded with different plugins in effect.) When an
3033 :     instrumented module is linked, whatever plugins are at that time
3034 :     enabled will come into effect for that module.
3035 :     +
3036 : jhr 4002 To enable the back-trace plugin, load library +$/trace-debug-profile.cm+
3037 :     and invoke +BackTrace.install()+ (_e.g._, from the interactive prompt).

3145 :     +
3146 :     * Arranged for the version tool to NOT kick in when rebuilding the system
3147 :     (makeml -rebuild, fixpt). Otherwise one would never reach a fixpoint.

3154 :     [2004/09/29]::
3155 :     +
3156 :     Implemented some CM magic to have
3157 :     file src/compiler/TopLevel/main/version.sml
3158 :     generated automagically.
3159 :     The version is taken from two files: config/version and config/release.
3160 :     The first is expected to contain a two-part version number such as 110.49.
3161 :     The second should contain a single number, but it may be missing.
3162 :     +
3163 :     If the environment variable VERSIONTOOL_BUMP_RELEASE is defined at the
3164 :     time the version tool is loaded (which is the first time you say CMB.make),
3165 :     then the tool will increment the value stored in config/release every
3166 :     time CMB.make is invoked.
3167 :     +
3168 :     The binfile format is now insensitive to anything beyond the first
3169 :     two components of a version number, so bumping the release does not render
3170 :     binfiles incompatible. Auto-bumping can be used to keep track of versions
3171 :     during development without invalidating existing binfiles.

3186 :     [2004/09/27]::
3187 :     +
3188 :     Added two pieces of functionality to the Controls interface:
3189 :     +
3190 : jhr 3995 [source,sml]
3191 :     ------------
3192 :     val save'restore: 'a control -> unit -> unit
3193 :     ------------
3194 : jhr 3992 +
3195 : jhr 3995 grabs the current value of the control in stage 1 and restores it
3196 :     in stage 2.
3197 : jhr 3992 +
3198 : jhr 3995 [source,sml]
3199 :     ------------
3200 :     val set' : 'a control * 'a -> unit -> unit
3201 :     ------------
3202 : jhr 3992 +
3203 : jhr 3995 stores the given value into the control in stage 2 (_i.e._, delayed)
3204 :     but does all error checking in stage 1.
3205 :     (This is for string controls that need to do parse their argument --
3206 :     something that might fail. In some cases, notably in CM, one
3207 :     already knows the intended argument but wants to delay the actual
3208 :     assignment until a time when error recovery would be more difficult.)
3209 : jhr 3992 +
3210 : jhr 3995 Also changed the handling of controls in tool arguments to classes "+sml+" and
3211 :     "+lazysml+":
3212 : jhr 4002 +
3213 : jhr 3995 --
3214 :     - use +Controls.save'restore+ as a more robust way of restoring the
3215 : jhr 3992 old value (in particular: without having to re-parse the string)
3216 : jhr 3995 - use controls to handle the "+overload+" keyword in the init group
3217 : jhr 3992 (I believe this change actually fixes a long-standing obscure bug.)

3222 :     //--------------------------------------------------------------------
3223 :     [2004/09/27]::
3224 :     +
3225 : jhr 3995 Added a new tool class called "+lazysml+" to CM's tool chest. The only
3226 :     difference to "+sml+" is that compilation is done with +Control.lazysml+
3227 :     set to true. A source of class "+lazysml+" is automatically recognized
3228 :     by a file name suffix of "+.lml+".
3229 : jhr 3992 +
3230 : jhr 3995 In addition to the above feature, the original class "+sml+" now also
3231 :     supports a tool argument "+lazy+" which has the same effect. As a
3232 : jhr 3992 result, the following three lines are equivalent:
3233 :     +
3234 : jhr 3995 ....................
3235 : jhr 3992 foo.sml : lazysml
3236 :     foo.sml : sml (lazy)
3237 :     foo.sml (lazy)
3238 : jhr 3995 ....................
3239 : jhr 3992 +
3240 :     The setting goes into effect both during parsing and during
3241 :     compilation. The original setting is restored right after parsing and
3242 :     after compilation, respectively.
3243 :     +
3244 :     In addition to all the above, there is also a general mechanism to set
3245 :     ANY of the "controls" that are available at the command line via
3246 : jhr 3995 "+-C...+" on a per-sml-file basis. The same rules that apply for "+lazy+"
3247 :     apply as well. (In fact, "+lazy+" is implemented as a special case of
3248 : jhr 3992 the general mechanism.)
3249 :     +
3250 : jhr 3995 The +.cm+ file syntax uses a new keyword tool argument called "+with+".
3251 : jhr 3992 There are several ways of indicating the desired settings:
3252 :     +
3253 : jhr 3995 ....................
3254 : jhr 3992 foo.sml (with:parser.quotations=true)
3255 :     foo.sml (with:(name:parser.quotations value:true))
3256 :     foo.sml (with:(name:name1 value:value1 name:name2 value:value2 ...))
3257 :     foo.sml (with:(name1=value1 name2=value2 ...))
3258 :     foo.sml (with:(name1=value1 name:name2 value:value2 name3=value3 ...))
3259 : jhr 3995 ....................
3260 : jhr 3992 +
3261 : jhr 3995 Another possible abbreviation is to leave out the +=v+ or +value:v+ part
3262 : jhr 3992 if the name refers to a boolean control (in which case the value is
3263 :     taken to be true). Thus, one could get lazy sml also by saying:
3264 :     +
3265 : jhr 3995 ....................
3266 : jhr 3992 foo.sml (with:parser.lazy-keyword=true)
3267 :     foo.sml (with:parser.lazy-keyword)
3268 :     foo.sml (with:(name:parser.lazy-keyword value:true))
3269 :     foo.sml (with:(name:parser.lazy-keyword))

3608 :     Changed the interface of structures Timer and Unix to match the most
3609 :     recent Basis spec.
3610 :     +
3611 :     In the case of Unix there still seems to be an open/weird issue:
3612 :     +
3613 :     The {text,bin}{In,Out}streamOf functions are supposed to create
3614 :     fresh streams whenever they are called -- as opposed to have them
3615 :     return the same stream every time. This design is supposed to
3616 :     prevent space leaks caused by proc values hanging on to streams.
3617 :     +
3618 :     The reap function, on the other hand, is supposed to close the
3619 :     streams. This cannot be done without having a handle on the
3620 :     stream in proc after all...
3621 :     +
3622 :     I took the liberty to implement the following stopgap solution:
3623 :     +
3624 :     The proc value hangs on to the most recently created stream(s).
3625 :     Reap closes those. If either or both of the two streams hadn't
3626 :     been created at all yet, then reap will close the corresponding
3627 :     file descriptors directly.
3628 :     +
3629 :     PS: I don't understand the original space leak argument anymore. If
3630 :     a proc hangs on to the imperative stream, then I/O operations on those
3631 :     will advance the state of the cached stream and avoid the space leak.

3644 :     +
3645 :     CM now ignores (but still accepts) the "owner" information in group
3646 :     descriptions. The owner of a group is its next enclosing
3647 :     library. Each group must have a unique owner. (There is a virtual
3648 :     "toplevel" library that owns groups which are not nested within a real
3649 :     library.) Previously, each group had to explicitly declare its owner,
3650 :     and CM would check that such a declaration is correct. The new scheme
3651 :     is to have CM check that for each group there is precisely one owning
3652 :     library.
3653 :     +
3654 :     The advantage of the new scheme is that the programmer no longer needs
3655 :     to maintain the somewhat annoying owner information. The downside is
3656 :     that CM cannot enforce the ownership rule across multiple runs of
3657 :     CM.make. Fortunately, enclosing the same group in two different
3658 :     libraries A and B which are not part of the same program does not
3659 :     cause real problems.

3707 :     +
3708 :     Hi,
3709 :     +
3710 :     Attached to this email you find a diff against sml/nj 110.45
3711 :     that will enable socket support under Windows.
3712 :     +
3713 :     To apply the patch (using unix or cygwin)
3714 :     1) gunzip runtime.diff.gz
3715 :     2) "cd" into "src/runtime" in the source tree of a fresh
3716 :     110.45 installation.
3717 :     3) patch -p 1 < [your/path/to]runtime.diff
3718 :     +
3719 :     The code compiles fine but has NOT yet been extensively tested.
3720 :     I only ran a few tests for basic socket client functionality
3721 :     (which worked fine). Especially the functions that use ioctl
3722 :     are not tested at all and might not work (see below).
3723 :     +
3724 :     I implemented this since we want to move to a newer version of sml/nj
3725 :     but need socket support in order to use it. This is the first time I
3726 :     even had a look at the sml/nj source, so please review my changes
3727 :     before making this part of the distribution! Here are a few issues
3728 :     that I think might be better for someone to solve who is more
3729 :     familiar with the sml/nj source (and socket programming):
3730 :     +
3731 :     - getnetbyaddr.c and getnetbyname.c will raise a "not implemented"
3732 :     exception since I could not figure out what the windows equivalent
3733 :     of these functions is
3734 :     +
3735 :     - In sockets-osdep.h there are a some #include statements that are
3736 :     only used in a few files that include sockets-osdep.h
3737 :     +
3738 :     - In smlnj-sock-lib.c, function init_fn() calls WSAStartup() but
3739 :     does not process its return value since I don't know how to
3740 :     report an error upwards.
3741 :     +
3742 :     - It would probably be good to have a call to WSACleanup() when
3743 :     the library is unloaded (if there is such a possibility).
3744 :     Otherwise I think Windows will take care of this automatically
3745 :     when the process finishes.
3746 :     +
3747 :     - I used ioctlsocket() as a replacement for ioctl() but I have
3748 :     no idea if that is actually the proper replacement on Windows.
3749 :     +
3750 :     - All these issues are marked in the code by "FIXME" comments.
3751 :     +
3752 :     We use sml/nj extensively in our products and are quite happy
3753 :     with it. I hope this contribution will help you.
3754 :     +
3755 :     Keep up the good work!

3946 :     [2003/09/26]::
3947 :     +
3948 :     I modified the read-eval-print loop so that the autoloader gets
3949 :     invoked whenever the prettyprinter tries to look up a symbol that
3950 :     is not currently defined in the toplevel environment but which
3951 :     appears in CM's autoload registry. As a result, we see far fewer of
3952 :     those ?.Foo.Bar.xxx names in the prettyprinter's output.
3953 :     +
3954 :     In addition to this I tried to clean up some pieces of the Basis
3955 :     implementation (_e.g._, Socket, Word8Array) in order to prevent other
3956 :     instances of these ?.Foo.Bar.xxx names from being printed.
3957 :     +
3958 :     The mechanism that picks names for types still needs some work, though.
3959 :     (Right now it seems that if there is a type A.t which is defined to
3960 :     be B.u, but B is unavailable at toplevel, then A.t gets printed as
3961 :     "?.B.u" although the perhaps more sensible solution would be to use
3962 :     "A.t" in this case. In other words, the prettyprinter should follow
3963 :     a chain of DEFtycs not farther than there are corresponding toplevel
3964 :     names in the current environment.)

3971 :     Another installer tweak: All the ML code for the installer is now
3972 :     compiled during CMB.make and put into a little library called
3973 :     $smlnj/installer.cm. The installation then simply invokes
3974 :     +

3976 :     sml -m $smlnj/installer.cm

3985 :     The new scheme guarantees that the ML code responsible for the installation
3986 :     is in sync with the APIs of the main system. Also, the installer is

3995 :     but excludes all non-blocking operations. Defined SOCKET (in Basis)
3996 :     and CML_SOCKET in terms of SYNCHRONOUS_SOCKET. Removed superfluous

4003 :     [2003/09/24]::
4004 :     +
4005 :     1. Fixed SOCKET API and implementation to match Basis spec.
4006 :     This required changing the internal representation of sockets to one
4007 :     that remembers (for each socket file descriptor) whether it is currently
4008 :     blocking or non-blocking. This state is maintained lazily (_i.e._, a system
4009 :     call is made only if the state actually needs to change).
4010 :     +
4011 :     2. OS-specific details of sockets were moved into separate files, thus
4012 :     making it possible to unify the bulk of the socket implementations
4013 :     between Unix and Win32.
4014 :     +
4015 :     3. CML's socket API changed accordingly.
4016 :     (Note that we need to remove non-blocking functions from this API
4017 :     since they are redundant in the case of CML!)
4018 :     +
4019 :     4. CML's socket implementation now makes use of non-blocking functions
4020 :     provided by Basis, thus removing all OS-dependent code from this part
4021 :     of CML.
4022 :     +
4023 :     5. Changed Real64.precision from 52 to 53. Minor cleanup in Real64 code.

4169 :     3. Edited source code throughout the system to make it compile again
4170 :     under 1. and 2. (In some cases code had to be added to have it
4171 :     match the new signatures.)
4172 :     4. MLRISC should be backward-compatible: the copies of the originals
4173 :     of files that needed to change under 3. were retained, the .cm files
4174 :     check the compiler version number and use old versions when
4175 :     appropriate.
4176 :     5. Changed type of OS.FileSys.readDir and Posix.FileSys.readdir to
4177 :     dirstream -> string option (in accordance with Basis spec).
4178 :     6. When generating code that counts lines, *ml-lex* used function
4179 :     CharVector.foldli, taking advantage of its old interface.
4180 :     This has been replaced with the corresponding code from
4181 :     CharVectorSlice. (html-lex must be re-lexed!)

4183 :     new MONO_ARRAY signature. (Do we need BitArraySlice?)
4184 :     8. Removed temporary additions (fromInternal, toInternal) from the
4185 :     (now obsolete) IntInf in smlnj-lib/Util.
4186 :     9. Cleaned up structure Byte.
4187 :     10. Added localOffset, scan, and fromString to Date (according to spec).
4188 :     Cleaned/corrected implementation of Date.
4189 :     (Still need to check for correctness; implement better canonicalizeDate.)
4190 :     11. Added "scan" to signature IEEE_REAL.
4191 :     12. Some improvements to IntInf [in particular: efficiency-hack for
4192 :     mod and rem when second operand is 2 (for parity checks).]
4193 :     13. Changed representation of type Time.time, using a single IntInf.int
4194 :     value counting microseconds. This considerably simplified the
4195 :     implementation of structure Time. We now support negative time
4196 :     values; scan and fromString handle signs.

4203 :     [2003/08/28]::
4204 :     +
4205 :     This is a major update which comes with a version number bump
4206 :     (110.42.99 -- yes, we are really close to 110.43 :-), NEW BOOTFILES,
4207 : jhr 4101 and an implementation of +IntInf+ in the Basis.
4208 :    
4209 : jhr 3992 There are a fairly large number of related changes and updates throughout
4210 :     the system:
4211 :     +
4212 :     Basis:
4213 :     - Implemented IntInf.
4214 :     - Made LargeInt a projection of IntInf (by filtering through INTEGER).
4215 :     - Added some missing Real64 operations, most notably Real.toLargeInt.
4216 :     - Added FixedInt as a synonym for Int32.
4217 :     +
4218 :     compiler:
4219 :     * Added support for a built-in intinf type.
4220 : jhr 4101 --
4221 : jhr 3992 - literals
4222 :     - pattern matching
4223 : jhr 4101 - conversion shortcuts (+Int32.fromLarge o Int.toLarge+ etc.)
4224 : jhr 3992 - overloading on literals and operations
4225 : jhr 4101 --
4226 : jhr 3992 This required adding a primitive type intinf, some additional
4227 :     primops, and implementations for several non-trivial intinf
4228 :     operations in Core. (The intinf type is completely abstract
4229 :     to the compiler; all operations get delegated back to the Core.)
4230 :     +
4231 :     * Intinf equality is handled by polyequal. However, the compiler
4232 :     does not print its usual warning in this case (since polyequal
4233 :     is the right thing to do there).
4234 :     +
4235 : jhr 4101 * Improved the organization of structure +InlineT+.
4236 : jhr 3992 +
4237 :     * A word about conversion primops:
4238 :     If conversions involving intinf do not cancel out during
4239 :     CPS contract, then the compiler must insert calls to Core functions.
4240 :     Since all core access must be resolved already during the FLINT
4241 :     translate phase, it would be too late a the time of CPS contract
4242 :     to add new Core calls. For this reason, conversion primops
4243 :     for intinf carry two arguments: 1. the numeric argument that
4244 :     they are supposed to convert, and 2. the Core function that
4245 :     can help with this conversion if necessary. If CPS contract
4246 :     eliminates a primop, then the associated Core function becomes
4247 :     dead and goes away. Intinf conversion primops that do not get
4248 :     eliminated by CPS contract get rewritten into calls of their
4249 :     core functions by a separate, new phase.

4251 :     interactive system:
4252 :     - Control.Print.intinfDepth controls max length of intinf constants
4253 :     being printed. (Analogous to Control.Print.stringDepth.)
4254 :     - Cleanup in printutil and pputil: got rid of unused stuff and
4255 :     duplicates; replaced some of the code with code that makes better
4256 :     use of library functionality.
4257 :     +
4258 :     CM:
4259 :     Bugfix: parse-errors in init group (system/smlnj/init/init.cmi)
4260 :     are no longer silent.
4261 :     +
4262 :     CKIT:
4263 :     Fixed mismatched uses of Int32 and LargeInt. I always decided
4264 :     in favor of LargeInt -- which is now the same as IntInf.
4265 :     CKIT-knowledgable people should check whether this is what's
4266 :     intended and otherwise change things back to using Int32 or
4267 :     FixedInt.
4268 :     +
4269 :     Throughout the code:
4270 :     Started using IntInf.int literals and built-in operations
4271 :     (_e.g._, comparison with 0) where this seems appropriate.

4277 :     [2003/08/13]::
4278 :     +
4279 :     Merging changes from the mcz-branch development branch into trunk.
4280 :     These changes involve replacement of the emulated old prettyprinter
4281 :     interface with direct use of the SML/NJ Lib PP library, and fixing
4282 :     of a couple of bugs (895, 1186) relating to error messages. A new
4283 :     prettyprinter for ast datatypes (Elaborator/print/ppast.{sig,sml})
4284 :     has been added.

4293 :     [2003/08/11]::
4294 :     +
4295 :     This patch restores SML/NJ's ability to run under win32. There are a
4296 :     number of changes, including fixes for several bugs that had gone
4297 :     unnoticed until now:
4298 :     +
4299 : jhr 4101 --
4300 :     * uname "CYGWIN_NT*" is recognized as win32 (This is relevant only when
4301 :     trying to run the win32 version from within cygwin.)
4302 :    
4303 :     * There are a number of simple .bat scripts that substitute for their
4304 :     corresponding Unix shell-scripts. (See below.)
4305 :    
4306 :     * The internals of *ml-build* have been modified slightly. The main
4307 :     difference is that instead of calling ".link-sml" (or link-sml.bat)
4308 :     using +OS.Process.system+, the ML process delegates this task back
4309 :     to the script. Otherwise problems arise in mixed environments such
4310 :     as Cygwin where scripts look and work like Unix scripts, but
4311 :     where OS.Process.system cannot run them.
4312 :    
4313 :     * In CM, the srcpath pickler used native pathname syntax -- which
4314 :     is incorrect in the case of cross-compilation. The new pickle format
4315 :     is independent of platform-specific naming conventions.
4316 :    
4317 :     * Path configuration files (such as lib/pathconfig) can now choose
4318 :     between native and standard syntax. Placing a line of the form
4319 : jhr 3992 +
4320 :     standard!
4321 :     +
4322 : jhr 4101 into the file causes all subsequent paths to be interpreted using
4323 :     CM standard pathname syntax (= Unix conventions); a line
4324 : jhr 3992 +
4325 :     native!
4326 :     +
4327 : jhr 4101 switches back to native style. This was needed so that
4328 :     path config files can be written portably, see src/system/pathconfig.
4329 :    
4330 :     * Runtime system:
4331 : jhr 3992 +
4332 : jhr 4101
