poly - the Poly/ML Standard ML implementation
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.
- Print the version of Poly/ML and exit.
- Print a list of the arguments and exit.
- Suppress the start-up message.
- 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.
- Normally if the ML code raises an unhandled exception control returns to
the ML shell. With this option the shell exits on an unhandled
- 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
- Run the IDE communications protocol rather than the normal read-eval-print
loop. Only suitable for running within a development environment.
- 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
- --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)
- --debug options
- Set various debugging options for the run-time system.
