* Priorities
============
A (High) to be fixed before release
B (Medium) desirable to fix at some point
C (Low) probably not worth wasting time on
* This is a list of things which need doing in the generic interface
====================================================================
A Structured review of complete system (2h hhg & tms)
A Update documentation, in particular document bugs and workarounds
(4h hhg & tms)
A Implement more generic mechanism for large undos (2h)
COQ: C-c u inside a Section should reset the whole section, then
redo defns
LEGO: consider Discharge; perhaps unrol to the beginning of the
module?
B Implement proof-find-previous-terminator and bind it to C-c C-a
(45min tms)
B Technical documentation to record expertise and allow users of other
proof systems to adopt generic package (40h hhg & tms)
B Port packages to XEmacs 20
A Fixing up errors caused by pbp-generated commands; currently, script
management unwisely assumes that pbp commands cannot fail (2h tms)
C pbp code doesn't quite accord with the tech report; in particular it
decodes annotations eagerly. Lazily would be faster, and it's what
the tech report claims
--- djs: probably not much faster, actually.
C It would be nice to have a version ported to emacs19 (or
20). Unfortunately, it's currently impossible to port the pbp code,
since emacs19 doesn't properly handle highlighting of nested
overlays. The bulk of the stuff dependent on which version of emacs
is running has been moved to proof-dependencies.el, but there are
doubtless differences in font-locking and menu code which will
require some work. One should check regularly if extents become
available in emacs19
B file handling could be more robust; perhaps one should always cd to
the directory corresponding to the script buffer (currently only
done for the buffer which starts up the proof system) (30min tms)
C LEGO and Coq modes overwrite each other.
C We need to go over to piped communication rather than ptys to fix
the (Solaris) ^G bug. In this circumstance there's a bug in the
eager annotation code
C Outline-mode does not work due to read-only restrictions of
protected region
* Here are things to be done to Lego mode
=========================================
A LEGO mode might incorporate changes to Coq mode menu, in particular
making help refer to the info file (30min tms)
A Sometimes e.g., ~tms/lego/imperative/recursion/Prepare_vc.l,
annotations are recorded in the object file. This needs to be
changed in the SML code. (initially 2h tms)
C Mechanism to save object file
A Equiv, Next,... aren't handled properly, because LEGO does not
refresh the proof state. Perhaps it would be easiest to get LEGO to
output more information in proof script mode (2h tms)
A Error messages need to be revised e.g., if an import fails, LEGO
outputs
Error in file: search: undefined or out of context: should
(* closing file ./blah.l; time= 0.010000 gc= 0.0 sys= 0.0 *)
Error: Unwinding to top-level
but script management only prints the last line. (5h tms)
* Here are things to be done to Coq mode
========================================
? There's a bug so the goal buffer isn't displaying everything that
happens.
C Sections and files are handled incorrectly.
A Update documentation to include C-c C-s. (10min hhg)
A Lifted nested lemmas respond incorrectly to C-c u: Coq gets sent the
correct command if I undo up to the lower lemma, but the buffer
undoes to the upper lemma. I.e., if I start Lemma x, then prove
Lemma y, then finish x, and undo lemma x, then lemma y gets undone
in the buffer as well. (45min hhg)
B Proof-by-Pointing (10h hhg)
