This is file README for Moscow ML 2.10.1 for Linux/Unix (August 2014) EXTENT OF THE IMPLEMENTATION The current version 2.10.1 of Moscow ML * implements the full Standard ML language, as revised 1997, including Modules and some extensions * yet is backwards compatible with versions prior to 2.00 * implements large parts of the new SML Basis Library * implements separate compilation * can produce compact stand-alone executables (a la Caml Light) * supports quotations and antiquotations, useful for metaprogramming * supports dynamic linking of external functions under Linux (x86 and Alpha), FreeBSD, NetBSD, Solaris, Digital Unix, HP-UX, MacOS, and MS Windows'95/98/NT/XP/Vista and possibly also 7 and 8. New in version 2.10.1 of Moscow ML * ML Server Pages added to examples * Build system cleaned up a bit New in version 2.10 of Moscow ML * Support for dynamic linking and callback from C also under MacOS X * There may now be 2 G globals (string literals etc) instead of 64 K * Bugs fixed: * The HTML files generated for mosmllib now have valid URLs * Substring.app more efficient * Recursive structure compilation (elabRecSigExp) fixed * Several errors in Mosmlcookie * Misplaced double quote in Msp.ahrefa * Exception Option wasn't available at top-level * Linker did not check stamps of linked-in units * Hash function now much faster on very long strings * Double alignment constraints now correct with gcc-3.2 and Solaris * Bug in Polyhash.filter * Socket library returned only first 16 bytes of UDP datagram * SML Basis Library changes: * String and Substring: added concatWith, isSuffix, isSubstring, full * ListPair: added zipEq, appEq, mapEq, foldlEq, foldrEq, allEq * Added ArraySlice and VectorSlice structures, also for Char and Word8 * Added find, findi, all, exists, collate to vector, array and slice structures * Added collate to List * Added update to vector structures * Path.{mkRelative,mkAbsolute} now take record arguments * Negative Time.time values allowed * OS.Process: new functions sleep and isSuccess; status not eqtype * Listsort: added eqclasses, merge, mergeUniq * Path: added functions isRoot, fromUnixPath, toUnixPath, and exception InvalidArc (bug report by Henning Niss) * TextIO: inputLine now have type instream -> string option * Array: added type abbreviation vector (bug report by Andrzej Wasowski) * FileSys: type access renamed to access_mode (bug report by Henning Niss) * Byte: unpackString{,Vec} now uses vector slices (bug report by Henning Niss) * Unix: added functions fromStatus, textInstreamOf, binInstreamOf, textOutstreamOf, binOutstreamOf, exit, and added phantom types to proc (bug report by Henning Niss) * Timer: added function checkCPUTimes * Word and Word8: added functions toLarge, toLargeX, and fromLarge (bug report by Martin Elsman) * General: added exception Span and made the type of the function 'before' less general (bug report by Henning Niss) * Added modules to mosmllib: * Buffer: mutable string buffers for fast and efficient concatenation of strings * Hashset: sets implemented by hash-tables * Rbset: ordered sets implemented by red-black trees * Redblackmap: maps implemented by red-black trees * Moscow ML is now developed in the open at github. SYSTEM REQUIREMENTS Compilation under Unix is best done using GNU make, gcc, and Perl. A binary installation requires 8 MB disk space; a source installation requires 25 MB disk space.

Hi, I have successfully built mosml
after git clone
. But after installing with:
$ DESTDIR=/tmp/mosml-install make install
if I try to execute mosml
in that directory:
$ /tmp/mosml-install/usr/local/bin/mosml
/tmp/mosml-install/usr/local/bin/mosml: 11: exec: /usr/local/bin/camlrunm: not found
it gives me an error saying that camlrunm
is not found.
I guess the path to camlrunm
is hard-coded into mosml
because camlrunm
is installed to the same directory $DESTDIR/usr/local/bin/
as mosml
.
The code
load "Time";
Time.fmt ~1 (Time.now());
should raise the Size
exception, but does not in Moscow ML. The simple fix is to change lines 37-38 of Time.sml to
fun fmt p r = Real.fmt (StringCvt.FIX (SOME p)) (r/1000000.0);
since Real.fmt
raises Size
on invalid precision specifications.
A better fix is
fun fmt p = if (p < 0)
then raise Size
else (fn r => Real.fmt (StringCvt.FIX (SOME p)) (r/1000000.0))
since it is consistent with how Real.fmt
treats invalid format specifications.
Make installers for Linux, OS-X and Windows and put them on the homepage.
I've rebuilt mosml compiler with cd src; make world; cd compiler; make promote; make clean; make promote
, on two different systems: ALT Linux/AMD64, Debian/mipsel32. md5sums of src/mosmlcmp
were different, which is really surprising. I have also 64-bit SPARC machine, which, unfortunately can't compile camlrunm
yet (but it looks like I can fix it).
Do you know why md5 sums were different?
While compiling one of the example programs, I get a syntax error:
$ mosmlc ./examples/modules/array.sml
File "./examples/modules/array.sml", line 7, characters 0-9:
! signature Array =
! ^^^^^^^^^
! Syntax error.
This also happens with this simple program:
structure MyList =
struct
fun each _ [] = ()
| each f (x :: xs) = (f x; each f xs)
end;
val _ = MyList.each print ["Hello, world!\n"];
$ ./bin/mosmlc example.sml
File "example.sml", line 7, characters 0-3:
! val _ = MyList.each print ["Hello, world!\n"];
! ^^^
! Syntax error.
Both files run properly with the interpreter, mosml
. This is running at tag ver-2.10.1
on Linux 4.1.4, armv6l.
It would be nice to have PackRealLittle as documented here: https://smlfamily.github.io/Basis/pack-float.html
Probably needs #62 to be implemented first.
PackReal32Little and PackReal64Little would also be useful, except that MosML does not have Real32.
I wrote this code in MacOS X 10.9.5 using mosml 2.10 installed from pkg file.
$ rlwrap mosml

Enter `quit();' to quit.
- load "IntInf";
> val it = () : unit
- IntInf.fromInt 1 = IntInf.fromInt 1;
! Toplevel input:
! IntInf.fromInt 1 = IntInf.fromInt 1;
! ^^^^^^^^^^^^^^^^
! Type clash: expression of type
! int/1
! cannot have equality type ''a
-
According to the basis library document
(http://sml-family.org/Basis/int-inf.html#section:0),
signature INT_INF includes INTEGER, and INTEGER has eqtype int.
So, I should write like "IntInf.fromInt 1 = IntInf.fromInt 1" using comparison operators.
Could you show me why IntInf is not eqtype, please?
Sorry for my poor english. Thank you.
Moscow ML seems to be applying functions the Caml way, rather than what is called for in the Definition of Standard ML. The manual says to report this deviation as a bug. For me, it's a show-stopping bug.
Example source code:
structure S = struct
fun shout_then_apply f = (print "Shouting.\n"; f)
fun id x = x
val _ = shout_then_apply id (print "Evaluating second argument.\n")
end
The standard says that the first print
should be called when shout_then_apply
is applied to id
, which is before the second print
is evaluated. But that's not what mosml does:
For comparison, here's output from MLton:
nr@homedog ©152/g/textbook> mosmlc -toplevel -o a mosmlbug.sml
nr@homedog ©152/g/textbook> ./a
Evaluating second argument.
Shouting.
nr@homedog ©152/g/textbook> mlton -output b mosmlbug.sml
nr@homedog ©152/g/textbook> ./b
Shouting.
Evaluating second argument.
nr@homedog ©152/g/textbook>
Standard ML of New Jersey also gets the evaluation order right.
For me, this is a show-stopping bug---is there any chance of getting it fixed?
If you go to http://mosml.org/mosmllib/ and click on the Misc link under all structures, it leads to http://mosml.org/mosmllib/Misc.html, which returns a 404
When trying to install mosml (2.00, 2.01, or 2.10.1) macOS Big Sur 11.2.2 from sources, I get:
make world
cd config; /Applications/Xcode.app/Contents/Developer/usr/bin/make all

Checking the sizes of integers and pointers...
This architecture seems to be neither 32 bits nor 64 bits.
Caml Light won't run on this architecture.

I have downloaded the newest snapshot of MosML, but make world
fails when trying to link camlrunm

Things seem to work if I just jam CFLAGS=-fPIC
into Makefile.inc
. I don't know if there is a better way to handle this.
I'm trying to build mosml on OSX. But there's no <malloc.h>
file on my system.
There is a <malloc/malloc.h>
and a <sys/malloc.h>
.
MosML elaborates the following code:
fun f x x = x;
as
> val ('a, 'b) f = fn : 'a -> 'b -> 'b
which does not conform to the Definition of SML'97. In particular, the code should simplify to
val rec f = fn vid1 => fn vid2 => case (vid1, vid2) of (x, x) => x;
which is in turn rejected by MosML with the following error message:
! Toplevel input:
! val rec f = fn vid1 => fn vid2 => case (vid1, vid2) of (x, x) => x;
! ^
! Illegal rebinding of x: the same value identifier is bound twice in a pattern
(Tested with version 2.10 on Arch Linux)
After build and install of mosml from the sources and performing the test, it fails with:

Dear mosml team,
I followed the instructions found in the install.txt and extracted the version downloaded from Git (here). But after extracting, my bin and lib folders seems to be empty.
What could be the reason?
Note: I couldn't extract using the command line option, which raised the following error. Hence I extracted using gui.
$ gzip -dc mosml-master.zip | tar xfv -
gzip: mosml-master.zip has more than one entry--rest ignored
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors
Debian/Ubuntu mosml packages put examples into /usr/share/doc/mosml/examples/examples
with double examples
in the path.
I think it's pretty clear that the Basis library says this should be a signed infinity value.

The mosml installer (pkg) installs its files in a directory (/usr/local
), which is used for Homebrew. This needs to be changed, so brew doctor
doesn't complain about unexpected header files and to avoid possible problems with other software.
Please use /usr
instead.
When you use %Z
in the format string to Date.fmt
you get random garbage:
- load"Date";

(Collateral bug from issue originally reported by Michael Norrish)
If the system's default make is not GNU make(in *BSD systems), 'make' is different from '$(MAKE)' and does not work with GNU make's makefile.
Thanks.
The content of the Mantis bugtracker I set up for Moscow ML at: http://friislarsen.net/mosmlmantis should be transfered to the issue tracker at github.
Open question, should only open bugs be transferred, or should closed bugs be transferred as well for the sake of history?
Currently the TODO contains lots of issues, maybe (some of) these should be triaged and entered into github issues.
Trying to compile the following file:
test.sml:
val _ = print (Int.toString (foldl (op*) 1 [2,4,5]))
gives me:
$ mosmlc test.sml
File "test.sml", line 1, characters 38-40:
! val _ = print (Int.toString (foldl (op*) 1 [2,4,5]))
! ^^
! Lexical error: unmatched comment bracket.
If I insert a space after the asterix, MosML will compile the file as well.
I understand that there's som ambiguity here, since *)
looks an awful lot like the end of a comment, but I can see that mlton compiles the same file without any troubles.
Is this the desired behavior for MosML?

Due to a change in GNU malloc, Moscow ML may crash on 64 bit architectures as well as on those 32 bit architectures that use glibc 2.7.

I am using Ubuntu 18.04 LTS on x86-64.
Also, the light grey text on mosml.org is extremely hard to read on the white background.
None of the man pages are installed by src/Makefile. Is that the intended behavior?
src/Makefile.inc defines MANDIR
, but it is not used elsewhere.
Lines 18 to 21 in ee355b2
After doing a make install
, the include/config.h
#include
s incorrect paths:
Lines 13-18:
#if defined(msdos)
#include "../config.dos/m.h"
#include "../config.dos/s.h"
#elif defined(WIN32)
#include "../config.w32/m.h"
#include "../config.w32/s.h"
The config.dos
and config.w32
directories only exist in the src/
folder, so the relative path is incorrect after the installation.
The implementation of Date
does not handle time zones correctly in all cases. Example:
- Date.fmt "%H:%M %Z" (Date.fromTimeUniv (Time.now()));
> val it = "15:20 CET" : string
I believe CET ought to be GMT or UTC.
By analogy with PolyML.Compiler.compilerVersionNumber in Poly/ML.
If one is writing code that you want to run on different systems, it is nice to know just what system one is running on when setting up things like compiles etc. I'd prefer not to have to use configure shell-scripts if the ML system itself could tell me what it was capable of from within the language.
The type `syserror` is declared to be an equality type in the Basis. In Moscow ML it is not.
Missing functions:
val errorName : syserror → string
val syserror : string → syserror option
Missing substructure: IO.

Here's an example of a non-exhaustive pattern in Moscow ML:
- fun foo (x::xs) = xs;
! Toplevel input:
! fun foo (x::xs) = xs;
! ^^^^^^^^^^^^^^^^
! Warning: pattern matching is not exhaustive
Here's an example of the same non-exhaustive pattern in OCaml:
# let foo (x::xs) = xs;;
Warning P: this pattern-matching is not exhaustive.
Here is an example of a value that is not matched:
[]
val foo : 'a list -> 'a list = <fun>
It'd be quite nice if Moscow ML, similarily to this, gave an example of an unmatched pattern.
When cross-compiling Moscow ML for Windows, mosmllex is left in two parts: header.exe and mosmllex. The old .w32 Makefile suggests that this is fixed by concatenating the two files into mosmllex.exe. Ideally, the cross_w32 Makefile directive should perform this concatenation.
So far I've run into two issues.
The first is that autoconf
gets stuck in an infinite loop when trying to determine the alignment constraints. The script works fine if I comment out the code for that and just add echo "#define ALIGNMENT" >> m.h
.
The second comes while running make world
. The build fails with:

I'd just use the provided Windows binaries, but I'm using mosmllex which doesn't seem to be provided in the Windows bindist.
can i know how to install mosml on ubuntu?
According to the documentation for OS.FileSys.tmpName, it should create a new temporary file:
This creates a new empty file with a unique name and returns the full pathname of the file. The named file will be readable and writable by the creating process, but, if the host operating systems supports it, not accessible by other users. This function can be used to create a temporary file that will not collide with other applications.
From: http://sml-family.org/Basis/os-file-sys.html#SIG:OS_FILE_SYS.tmpName:VAL
It seems like we are using tmpnam(3)
, which is deprecated, exactly because it doesn't actually create the file, but merely returns a suitable filename for a temporary file. This could lead to security issues.
Since August, SML/NJ uses mkstemp
(at least on newer systems where it is supported) such that a file is actually created.
SML/NJ implementation: http://smlnj-gforge.cs.uchicago.edu/scm/viewvc.php/sml/trunk/runtime/c-libs/posix-os/tmpname.c?view=markup&root=smlnj
The code around
http://github.com/kfl/mosml/blob/master/src/runtime/str.c#L82
hardcodes the LC_TYPE possibilities and assume that a non-iso-8859-1 encoding is a non-iso charset. There are several subtle problems with this choice.
First of all, utf-8 might be used. Second, iso-8859-15 is also in use at several places. I hypothesize that the current solution will lead to subtle bugs.
The installer link on mosml.org, https://github.com/kfl/mosml/releases/download/ver-2.10.1/mosml-setup-2.10.1.exe, leads to a 404 page.
Possibly related to #44.
Moscow ML appears to be lacking the structure Text
(and matching signature TEXT
) required by the basis library standard. (Table 2.2 in "The Standard ML Basis Library")
The signature is also available here.
Problem 1: For some reason, ../../config/m.h
is not included:
~/Projects/mosml/src/dynlibs/msocket $ make
gcc -Dunix -O2 -fno-defer-pop -fPIC -I../../runtime -c -o msocket.o msocket.c
In file included from ../../runtime/mlvalues.h:5:0,
from msocket.c:32:
../../runtime/config.h:4:15: fatal fejl: m.h: Ingen sådan fil eller filkatalog
#include "m.h"
^
oversættelse afsluttede.
make: *** [msocket.o] Fejl 1
Adding -I../../config to https://github.com/kfl/mosml/blob/Rel-2.10/src/dynlibs/msocket/Makefile#L10 fixes this temporarily, but you probably want to refer to this directory differently.
Problem 2: When I make install
, it copies libmsocket.so wrongly into my library directory:
~/Projects/mosml/src/dynlibs/msocket $ make install
cp libmsocket.so /home/simon/mosml/lib/mosml
Now, the issue isn't that it ends up in a subdirectory in lib/ -- this, I'm sure, is just a preference -- but since I don't have a directory called mosml/, libmsocket.so ends up being called mosml!
~/mosml/lib $ file mosml
mosml: ELF 64-bit LSB shared object, x86-64 [...]
https://github.com/kfl/mosml/blob/Rel-2.10/src/dynlibs/msocket/Makefile#L10 should probably be fixed so it at least ensures that it lands in that directory and not as the directory.
Real.fromString
may raise Overflow
, if presented with too large or too small a value.
Example:
load "Real";
val a = Real.fromString "1e-400";
val b = Real.fromString "1e400";
As far as I can tell, the specification says, that in these cases it should return zero (if too small in magnitude) or infinity (if too large in magnitude).
In https://mosml.org/mosmllib/, the links for the "MySQL" and "Graphics" structures are broken.
https://mosml.org/mosmllib/MySQL.html
should be https://mosml.org/mosmllib/Mysql.html instead.Graphics
structure.Related: #52
Currently, real
is an eqtype
which it shouldn't be, according to the SML Standard (see Appendix C). In particular, the following code should fail to elaborate:
1.0 = 1.0;
fn x => x = 1.0;
Further, the current equality on real
does not work too well (as one would expect, I'd say):
