Hi Brian,
This is an artefact I forgot to remove. Changeset dc36cd801694 should
correct this. I am sorry for any inconvenience.

* References 'trace_simp' and 'debug_simp' have been replaced by
configuration options stored in the context. Enabling tracing
(the case of debugging is similar) in proofs works via
using [[trace_simp=true]]
Tracing is then active for all invocations of the simplifier

* New testing tool "Mirabelle" for automated (proof) tools. Applies several
tools and tactics like sledgehammer, metis, or quickcheck, to every proof step

New proof method "smt" for a combination of first-order logic
with equality, linear and nonlinear (natural/integer/real)
arithmetic, and fixed-size bitvectors; there is also basic
support for higher-order features (esp. lambda abstractions).
It is an incomplete decision procedure based on external
SMT's timeout option is also measured in seconds, and this is the
case since its beginning. I found this a natural decision, and no one
has ever objected to it.

How about providing a parse function "time_of_string" which turns
strings like "30s" or "15ms" into proper times, and possibly adding a
configuration option scheme for times (besides the existing bool, int
and string schemes)? It seems that this could and should be provided

Hi,
There exists a theorem called "induct" in HOL, which changes after
every datatype declaration. What is the rationale behind this
theorem? Is it required for a particular purpose or just a forgotten
remainder of previous tunings? Shouldn't this suprising behaviour be
eliminated? Note that e
Hi Steve,
An arbitrary development snapshot of Isabelle is not required to run
as expected, but many snapshots do. Since your question is related to
such an arbitray version of Isabelle, I took the freedom to move your

Hi,
With changeset 3214c39777ab, the SMT solvers have been turned into
components.
As a consequence, the now obsolete environment variables
(in settings files) CVC3_SOLVER, YICES_SOLVER, and Z3_SOLVER should be
removed. This only applies if you have used the smt method so before.

Hi,
To all of you who already copied the SMT solvers (CVC3, Yices, or Z3)

Hi,
Until March 11, Google is looking for mentoring organization for this
year's Summer of Code, a two-month period where students from all over
the world improve open source software/projects.

Hi,
We are in the process of applying as a mentoring organization for this
year's Google Summer of Code (SoC). Some 150 open-source
organizations and some thousand students take part in SoC every year
-- and Google announced to accept more organizations this year.
http://socghop.appspot.com/gs
The website for the project ideas is actually (note the hyphen instead
of the underscore):

Thanks to Christian Sternagel for reporting this.
Please don't hesitate to submit project ideas,

Hi Clemens,
Please note that Z3's license explicitly allows distribution for
non-commercial purposes such as teaching, academic research or public
demonstrations. Although Isabelle's BSD-style license would allow
Isabelle to be applied to commercial applications, too, it still is a

Hi,
Given to bindings (i.e., instances of Binding.binding), how are they
supposed to be compared?
Here is a more concrete example. Assume there is a declaration such
as:
declare_foo name = ...
which declares "name" as some new foo-entity. For later reference,
the declared foo-entities are b
Hi Gerwin,
This is because by default the smt method tries to reconstruct the
proof of Z3. For bitvectors, however, there is currently no Z3 proof
reconstruction. You might want to invoke the smt method as an oracle:
lemma "(x :: 8 word) + x = 2 * x"
using [[smt_oracle]]

Hi,
When the JDK is not given in the PATH variable, the command "isabelle

This is at least the case for hg id 08c22e8ffe70.
The problem occurs with Cygwin where the JDK is provided as a
