#197 fixed Non-persistance of Unicode Tokens / Math Menu (Carbon Emacs 1.6.0) David Aspinall Makarius
Description

Using native Carbon Emacs 1.6.0 on Mac OS 10.4.x the Unicode Tokens and Unicode Math Menu custom settings do not really persist.

For example: start Proof General (via isar/interface script), then enable both options --- works fine. Now safe safe options: resulting .emacs file only holds information for isar-maths-menu-enable and when restarting PG/Emacs only this option is enabled. After editing the .emacs file to set isar-unicode-tokens-enable as well, the corresponding menu item is ticked, but shaded, i.e. cannot be changed. Moreover, neither this mode nor the math menu are enabled.

#198 fixed Prover executable not found when running without interface script David Aspinall Makarius
Description

Using Carbon Emacs 1.6.0 without the isar/interface script, but loading .../PG/generic/proof-site.el manually, results in a non-functional environment.

When enabling PG by vising a thy file, the location of isatool is queried as expected. Nevertheless, trying to start the prover produces this error: Searching for program: no such file or directory, isabelle

A brief look at the elisp sources reveals a slightly untidy situation: isatool and isabelle executable locations are not really corellated. With isatool available one could just do isatool getenv -b ISABELLE to get the proper isabelle executable as well, instead there are funny attempts to guess at the PATH etc.

#201 fixed X-Symbol only half enabled (Emacs: yes, prover: no) David Aspinall Makarius
Description

Linux (SuSE or Ubuntu) and xemacs-21.4.x

Running the isabelle-interface script with option -x true (for X-Symbols) does not fully enable xsymbols mode; in the Emacs buffer symbols are rendered as expected, but the prover does not have the "xsymbols" print_mode enabled.

After manual disabling and re-enabling in the PG/Options menu, xsymbols work as expected.
