From d64389d34f3494b97c67b7a6094123f1a699040c Mon Sep 17 00:00:00 2001 From: David Aspinall Date: Thu, 13 Dec 2007 12:58:11 +0000 Subject: Deleted file --- lego/todo | 44 -------------------------------------------- 1 file changed, 44 deletions(-) delete mode 100644 lego/todo (limited to 'lego') diff --git a/lego/todo b/lego/todo deleted file mode 100644 index dc0b1f28..00000000 --- a/lego/todo +++ /dev/null @@ -1,44 +0,0 @@ --*- mode:outline -*- - -* Things to do for LEGO - -See also ../todo for generic things to do, priority codes. - -** C Improve X-Symbol support. - -** D Fix Pbp implementation in LEGO itself (10h) - -** D In LEGO, apart from Goal...Save pairs, we have - declaration...discharge pairs. See the section "Granularity of - Atomic Commands" for a proposal on how to generalise the current - implementation so that it can also deal with "Discharge". - [See also the Coq problem with Sections] (6h) - -** D Inoking an "Expand" command produces a new proof state. But this is - incorrectly displayed in the response buffer and not the goals - buffer because special annotations are missing. Presumably, one - ought to replace "Toplevel.Pr()" by "Toplevel.PR()" in the - definition of "Expand" (see file newtop.sml [Version 1.4]).

Forget for a definition when inside - a proofstate kills off the whole proofstate. Effectively, - the definition is *global* rather than local to the proofstate, - and could perhaps be lifted to before the goal - (with the lift-global nonsense not so daft after all? Editing - behind the user's back is still objectionable though). - Another alternative fix would be to trigger some retraction action - on seeing the "Abort" regexp, rather than assuming it is the result of - some retraction action. More generally this could be used for error - handling. - -** D Improve legotags. It cannot handle lists e.g., with - [x,y:nat]; - it only tags x but not y. [The same problem exists for coqtags] - -** X Mechanism to save object file. Specifically, after having processed - a script (interactively), it would be nice if one could now save the - buffer in object format. At the moment, it only gets converted - (automatically) when it is read in indirectly at a later stage. - However, there is currently no LEGO command to do this. [4h] -- cgit v1.2.3
