-*- outline -*- * Summary of Changes for Proof General 3.1 from 3.0 ** New instantiations of Proof General! *** HOL 98 (http://www.cl.cam.ac.uk/Research/HVG/HOL/HOL.html) by David Aspinall. This is a fairly basic Proof General instance only, hopefully to entice HOL users so that one of them may improve it. I don't plan to maintain or improve this instantiation myself. (Nevertheless, please report problems as usual to proofgen@dcs.ed.ac.uk) See README in the hol98 directory for more details. *** Plastic (http://www.dur.ac.uk/CARG/plastic.html) (ongoing work) by Paul Callaghan . The Plastic system itself is not yet publicly available, so this is only included in the developers tar file. ** Generic Changes *** Added key binding C-c C-BS and menu entry for delete last command This restores the old function of the sequence "C-u C-c C-u" onto a safer key. In version 3.0 it was only available via control-button2 in the goals buffer. The function invoked is `proof-undo-and-delete-last-successful-command'. *** Separate README and BUGS files for each supported prover Check these files for detail of support and issues with each prover. *** Names of shell, goals, script buffers now based on proof assistant name Basing the name on the command isn't very abstract and leads to strange names for some provers, "coqtop" and "hol.unquote". Now we just use the lower case of the proof assistant name. *** Fixes for supporting Japanese versions of Emacs which have older CL macs. Problems occurred with CL macs with Japanicised documentation, defined in "egg.el". Japanese Emacs users, please report any other problems you find, they may be fixable for similar reasons. Better still, report these compatibility problems also to the Japanese Emacs developers, I don't know who to contact. *** Minor bug fix for duplicated short output. Only seen with "val x=1" or similar very short messages. We now set proof-shell-eager-annotation-start-length appropriately. *** Bug fix with .thy files and X-Symbol mode Subsequently visited theory files would have X-Symbols broken. *** Bug fix for (non-mule) FSF Emacs 20.5. Emacs would freeze when starting proof assistant due to character matching problem. *** Fix for infamous Solaris ^G problem: proof-shell-process-connection-type A user (or proof assistant configuration) can now specify whether to use pty or piped communication. This is to fix the problem that Solaris users have (because of a Solaris bug), when lots of ^G's appear. The default setting for proof-shell-process-connection-type is made by calling uname, if possible. If this contains "sun" then proof-shell-process-connection-type is set to nil for using pipes. Otherwise we use ptys which are to be prefered over pipes because pipes can become full or lose data, and pipes don't work which some proof assistants. If necessary, you can override this by customization, as usual. *** Added new configuration hook: proof-shell-pre-interrupt-hook This is added particularly for Isabelle running with Poly/ML, which requires interaction after an interrupt. *** Minor cosmetic improvement Name of proof assistant "Start Isabelle" etc. in menu. ** Coq Changes *** Incomplete handling of Section Coq PG will now issue Reset commands for sections. This still doesn't mirror the undo behaviour of sections properly, which should be treated as atomic, but it means that you can retract a file with sections in, at least. ** LEGO Changes *** Fix for error messages, now properly displays "cannot assume" message. ** Isabelle Changes *** Fix for Poly/ML with interrupts: use proof-shell-pre-interrupt-hook ** Isar Changes *** Syntax tweaks. ** Changes for developers to note *** todo files added for each prover (todo split from global todo).
