#166 fixed Out of sync on illegal escape character David Aspinall Peter Lammich
Description

PG-Emacs: 3.7pre071112 Isabelle: 2007

Here is a reproducible way to get ProofGeneral 3.7pre071112 out of sync with the isabelle2007 process, simply process this theory:

theory Scratch imports Main begin

lemma X: "a=b ==> b=a" by simp -- "Text with \illegal escape sequence"

end

This happens quite often if you insert latex in your formal comment and forget to convert "..." to {*...*} syntax. Having to restart Isabelle each time is annoying for large theories.

#167 invalid GNU Emacs 22.1.1 allows only one undo in a row from the toolbar while C-c C-u works David Aspinall An Isabelle Developer
Description

I use Isabelle 2007 with PG 3.7pre071112 under GNU Emacs 22.1.1 (i586-suse-linux-gnu, GTK+ Version 2.12.0) of 2007-11-24 on dede (part of opeSUSE 10.3).

The undo facility for proof steps works from the keyboard (C-c C-u), but not twice in a row when klicking on the Undo button on the tool bar of Emacs. One may alternate C-c C-u and the Undo button, though.

Yours sincerely, Ralph Matthes www.irit.fr/~Ralph.Matthes/
