NAME

       poly - the Poly/ML Standard ML implementation

SYNOPSIS

       poly

DESCRIPTION

       poly  starts  the  Poly/ML  shell.  Poly/ML is an implementation of Standard ML written by David Matthews
       originally at the University of Cambridge and maintained as a project supported by contributors.

OPTIONS

       -v     Print the version of Poly/ML and exit.

       --help Print a list of the arguments and exit.

       -q     Suppress the start-up message.

       -i     Interactive mode.  Output a prompt for each input line.  This is the default if input  is  from  a
              terminal.

       --use FILE
              Reads input from FILE as though executing the ML command 'use "FILE";' before the ML shell starts.

       --eval STRING
              Compiles and executes STRING as ML before the ML shell starts.

       --error-exit
              Normally  if the ML code raises an unhandled exception control returns to the ML shell.  With this
              option the shell exits on an unhandled exception.

       --with-markup
              Include extra mark-up information when printing.  This is only suitable when Poly/ML is run  under
              an environment that is able to decode the additional information.

       --ideprotocol
              Run  the  IDE  communications protocol rather than the normal read-eval-print loop.  Only suitable
              for running within a development environment.

       --script
              The input is a shell script.  The first line is skipped if it begins with #!.

       -H  size
              Sets the initial heap size.  The size may be written as a number optionally followed by K, M or  G
              representing  kilobytes, megabytes or gigabytes.  If none of these is given the number is taken as
              megabytes.

       --minheap size
              Set the minimum heap size.  The heap will not shrink below this value.

       --maxheap size
              Set the maximum heap size.  The heap will not grow above this value.

       --gcpercent percent
              Set the target percentage of time that the code should spend in the garbage collector.   The  heap
              sizer  will  attempt  to  set the heap size to achieve this target consistent with the minimum and
              maximum heap sizes given by the arguments and also consistent with keeping paging under control.

       --gcthreads threads
              Sets the number of threads used in the parallel garbage collector.  Setting this to 1  forces  the
              garbage  collector  to be single-threaded.  The value 0, the default, is taken to be the number of
              processors (cores) available.

       --debug options
              Set various debugging options for the run-time system.
