lib: Remove malformed comment.
...
This comment looks like a typo, in that it doesn't add to comprehension of this
theory, and it trips up LaTeX when generating a document.

lib: set: Add "filter" function for sets.
...
Can be more efficient than "Symset.dest x |> filter |> Symset.make"
because we know that the ordering is unmodified by filter.
2014-12-03 14:49:12 +11:00

Renamed "focus" to "subgoal". Used correct keyword tag (prf_goal) to fix batch processing.
2014-12-02 13:56:43 +11:00
b22a384931
lib: Add "solves" tactic.
...
Essentially does a "find_theorems solves" and automatically applies the
result.
The author makes no guarantees about the maintainability of proofs using
such a tactic.

Surprisingly tedious.

01490fd1f2
lib: Random word lemmas about shift-left / shift-right / divide-by-zero.
...
Existing lemmas are (all?) conditional on the word size. These lemmas
are unconditional, albeit only work in the special case of "x >> 1" and
"x << 1".

nicta-tools: Add "solved" tactic.
...
Ensures that all subgoals have been solved. If not, the tactic will fail
(causing backtracking).
Useful for creating proofs of the form:
apply ((make_lots_of_subgoals, auto, solved)[1])
where you can be sure that the current subgoal will either be entirely
discharged or left untouched.

NICTACompat: Disable "Trace_Attrib".
...
Loading "Trace_Attrib" causes strange, unexplained lock-ups in
Isabelle/jEdit (and possibly Isabelle build). In particular, at random
times shortly after Trace_Attrib is loaded, everything will stop
processing with the CPU at 0%.
The root cause of this is currently unknown. This patch disables it
until the problem can be tracked down further.

focus: Get "Focus.thy" working on Isabelle 2014.
...
Was investigating if Focus could help solve a particular problem
(involving "apply subst" not being able to work with bound variables).
Didn't solve the particular problem I was facing, but committing the fix
to Focus none-the-less.
