Inspecting structures
by ramana.kumar＠gmail.com 27 Jan '16

27 Jan '16

Is there a way to look at the contents (i.e. signature) of a structure without opening it? (I suppose you could just open it then call a lot of PolyML.Compiler.forgetXXX, but that's quite tedious) Also, is it possible to retrieve the long path of an identifier in scope? Something that will, for example, take the rev in scope and say that it came from List. Finally, what about searching for an identifier that would come into scope if you opened some structures?

polyc and poly --script
by rene.neumann＠in.tum.de 24 Mar '15

Hi, two completely orthogonal questions/remarks for PolyML 5.5.1: 1.) When building PolyML with '--with-system-libffi' the '-lffi' part is missing in the linker line in polyc. 2.) Is it somehow possible to see if an ML file is run via 'poly --script' or as a standalone executable? Because for the one the logic has to be wrapped in 'fun main ()', and for the other it should not :). (Ie, what I want: if is_script then main() else () ) Thanks, Ren? -- Ren?

[Fwd: Re: [polyml] Building Poly/ML on MacOS X 10.6]

What has happened? but it was a false alarm: my make file was wrong for other reasons and the absence of PolyML.Compiler.printTypesWithStructureName was not relevant. No doubt there are good reasons why this variable has been withdrawn. Regards, Rob.

Isabelle/ML IDE
by makarius＠sketis.net 29 Sep '14

Dear friends of Poly/ML, or Standard ML in general, Isabelle2013-2 is now available from the usual mirror sites: Cambridge (UK) http://www.cl.cam.ac.uk/research/hvg/Isabelle/ Munich (Germany) http://isabelle.in.tum.de/ Sydney (Australia) http://mirror.cse.unsw.edu.au/pub/isabelle/ It is mainly an environment for interactive and automated theorem proving, but the integration of Isabelle/ML into the Prover IDE makes it suitable for general Standard ML development (potentially in teaching scenarios). After downloading / unpacking / running the main application of Isabelle/jEdit, the Documentation panel on the right-hand side gives quick access to Examples, notably src/HOL/ex/ML.thy for some Isabelle/ML basics. The manual on Isabelle/jEdit in the same panel provides further details on the IDE, which is based on the jEdit text editor. Makarius

Motif in Poly/ML: sometimes works, sometimes not
by piotr.trojanek＠gmail.com 01 Sep '14

01 Sep '14

Dear Poly/ML experts, I copy-pasted Motif code from "Poly/ML for Motif: Quick Reference Manual", sections 1.3 and 1.4. When I start poly session and load this code with "use" I sometimes get a Motif window but sometimes do not. I am running polyml 5.5.2 on x86_64 Ubuntu, compiled with "--with-x --enable-shared" against Open Motif 2.3.4. Am I missing something? -- Regards, Piotr Trojanek

Poly/ML Process Monitor
by tjark.weber＠it.uu.se 20 Aug '14

20 Aug '14

We would like to announce a first version of a graphical process monitoring application for Poly/ML. The monitor displays data regarding, e.g., CPU time, memory footprint, garbage collection and threads of running Poly/ML processes. It is available from https://bitbucket.org/tjark/poly-ml-monitor The monitor is currently available for Linux only. It was written by Magnus Stenqvist and me and relies on Poly/ML's statistics feature, which was implemented by David Matthews. Feedback is welcome. Best, Tjark

measuring memory usage
by u5028081＠anu.edu.au 18 Aug '14

18 Aug '14

Hi all, Is it possible to measure the memory usage involved in a particular function call from within PolyML 5.5.0? I'm trying to figure out how much memory my vote-counting function uses to count a variety of lists of votes. I'm randomly generating the vote lists, and the functions I'm using for generating the lists seem to use more memory than the count itself. I can't measure what I need with OS tools because they return the memory used to generate the vote lists (because it's larger). I'm not sure where to look for functions of this nature, or if they're even provided in PolyML. Any help appreciated. Thanks in advance, Tom
