Ticket Resolution Summary Owner Reporter
#199 fixed Allow use of Isabelle.command to wrap commands singly David Aspinall David Aspinall
Description

Isabelle.command allows additional "properties" to be attached to individual commands when they are processed by Isar. Example properties are file name and line number (Isabelle Position type), which are not maintained by the top-level loop, but would be useful to get error messages to include this information when processing interactively.

#52 fixed An issue with current version of Trac David Aspinall Graham Dutton
Description

Some things to be careful of when using this Trac:

On editing a ticket, after every invocation of Preview, "assign to" returns to the active user, rather than retaining the initial selection.

Also, there seems to be no way to edit a ticket summary after the ticket has been created, which is a problem for empty-titled tickets.

Perhaps these should be submitted to Trac's own bug list.

Description

If you have the below code, then place the caret at the end of the "Case" line and press Ctrl+J (or Enter, TAB), Emacs will spin up and use 100% of the CPU. This is on 4.1-RC4.
