Inspecting structures
by ramana.kumar＠gmail.com 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 No doubt there are good reasons why this variable has been withdrawn.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

can't quit sessions
by u5028081＠anu.edu.au 31 Jul '14

Hi all, I'm using PolyML 5.5.0 to run some tests as a batch job and I can't figure out how to quit without using ^D (which I can't feed in automatically when batching things). I've tried using "PolyML.quit ();" and "PolyML.exit 0;" but neither of these work. I'm opening the PolyML structure first (open PolyML;) but I'm still getting errors saying that the commands haven't been declared. I can use some other functions defined in PolyML such as "PolyML.use", but not all (for instance "cd" isn't available). Seems the documentation is incorrect? http://www.polyml.org/docs/Intro1.html Can anyone help me out on this one? Thanks in advance, Tom

.polyml and poly-stats
by makarius＠sketis.net 02 Jul '14

02 Jul '14

Just a quick question, before I study the Poly/ML sources in detail. What are the conditions under which Poly/ML 5.5.2 creates a directory $HOME/.polyml and puts poly-stats files there? I have recently found by accident that I have hundreds of such files lying around. Maybe I just got some Poly/ML build/run options wrong, such that statistics are enabled accidentally. I am also using PolyML.Statistics.getLocalStats, but shouldn't the shared-memory file be for global stats only? Makarius
