<title>Tools 2.4</title>
<section>
<title>Fixed Bugs and Malfunctions</title>
<list type="bulleted">
<item>
<p>The Erlang Emacs mode now properly handles strings that
have $ or ^ as the last character.</p>
<p>Own Id: OTP-4697</p>
</item>
<item>
<p><c>xref</c>: The unresolved arity (-1) is now recognized
in analyses and queries.</p>
<p>Own Id: OTP-4778</p>
</item>
<item>
<p><c>cover</c> does no longer hang if an interface function
is called on a remote node - it returns
<c>{error,not_main_node}</c>.</p>
<p>Own Id: OTP-5031</p>
</item>
<item>
<p><c>fprof</c>: Time spent in the last function in a chain,
i.e. a function which did not call another function, and
the time when a process was scheduled out, was charged on
the above function. This resulted in own time in many
cases being bigger than acc time since the time a process
was scheduled out was charged on the function from which
the process was scheduled out. This is now corrected.</p>
<p>Own Id: OTP-5073</p>
</item>
<item>
<p>Previous patch from open source messed up \M-q so part of
that patch was backed out.</p>
<p>Own Id: OTP-5074</p>
</item>
<item>
<p><c>cover</c>: Added "Exclude Included Functions". If
"real code" is included in a modules which is cover
compiled, there will be no bumps for lines in the
included file. Earlier this would cause faulty bumps for
lines in the module, i.e. if the code was on line 4 in
the included file it would produce a bump for line 4 in
the module. Lines in included files are now just
disregarded.</p>

<section>
<title>Improvements and New Features</title>
<list type="bulleted">
<item>
<p>Added support for try-catch to the Erlang mode for Emacs.
However there are still some known problems with some of
the more advanced variants especially including separate
of-clauses.</p>
<p>Own Id: OTP-4594</p>
</item>
<item>
<p>Improvements for support of Emacs 21 contributed by Dave
Love. The bulk of the changes are actually cosmetic
commentary/doc fixes. The significant ones make it play
better with Emacs 21 with up-to-date facilities. In
particular, support for compilation error messages from
an inferior erl (as opposed to batch compilation) works
in the released Emacs 21, and currently with the
development Emacs.</p>
<p>Own Id: OTP-5019</p>
</item>
<item>
<p>Added a skeletons for an Erlang test-suite for both the
ts-frontend and the ct-frontend (this frontend is
Ericsson internal). Also altered some of the old
skeletons to get a uniform look and feel.</p>
<p>Own Id: OTP-5058</p>
</item>
<item>
<p>The Erlang mode for Emacs now supports the new guard
<c>is_boolean</c>.</p>
<p>Own Id: OTP-5059</p>
</item>
<item>
<p><c>cover</c>: Adjustments to handle new syntax of
try-catch.</p>

<section>
<title>Tools 2.3</title>
<section>
<title>Fixed Bugs and Malfunctions</title>
<list type="bulleted">
<item>
<p>Totally rewritten the interface for WebCover. Can now
compile both <c>.erl</c> and <c>.beam</c> files and
export/import cover data.</p>
<p>Own Id: OTP-4706</p>
</item>
<item>
<p><c>cover</c> does no longer report coverage on lines which
are not executed.</p>
<p>Own Id: OTP-4734</p>
</item>
<item>
<p>Erlang mode for Emacs: Fixed so that the generation of new
function clauses works also for guarded functions.</p>
<p>Own Id: OTP-3697</p>
</item>
<item>
<p>Erlang mode for Emacs: Fixed so that you do not get
the error message "unbalanced parenthesis" when indenting
correct code including bit syntax.</p>
<p>Own Id: OTP-4526</p>
</item>
<item>
<p>Erlang mode for Emacs: The guard <c>function</c> is now
colored.</p>
<p>Own Id: OTP-4533</p>
</item>
<item>
<p>Erlang mode for Emacs: Indentation of macros is handled
correctly in all cases.</p>
<p>Own Id: OTP-4561, OTP-4687</p>
</item>
<item>
<p><c>is_*</c> guards are now colored.</p>
<p>Own Id: OTP-4562</p>
</item>
<item>
<p>Erlang mode for Emacs: Now handles the fact that a function
argument may be a guard expression. (That is useful when
writing test case code.)</p>
<p>Own Id: OTP-4579</p>
</item>
<item>
<p>Erlang mode for Emacs: Keywords <c>andalso</c> and
<c>orelse</c> are now colored.</p>
<p>Own Id: OTP-4580</p>
</item>
<item>
<p>Erlang mode for Emacs: Fixed bug in function that calculates
the arity of an Erlang function.</p>
<p>Own Id: OTP-4581</p>
</item>
</list>
</section>
<section>
<title>Improvements and New Features</title>
<list type="bulleted">
<item>
<p>Added functions <c>cover:start(Nodes)</c> and
<c>cover:stop(Nodes)</c>. Cover compiled modules will be
loaded on all nodes added with <c>cover:start(Nodes)</c>.
<c>cover:stop(Nodes)</c> will collect coverage data from
the stopped nodes and merge it with data collected on
the main (controller) node.</p>
<p><c>cover:analyse/1,2,3</c> and
<c>cover:analyse_to_file/1,2,3</c> will also collect data
from all nodes before analysing.</p>
<p>Own Id: OTP-4177</p>
</item>
<item>
<p>The module attribute tag <c>deprecated</c> is used by
<c>xref</c> to find calls to deprecated functions.
The <c>m/1</c>, <c>d/1</c>, and <c>analyze/2,3</c> functions
have been updated to return calls to deprecated functions.
See also <c>xref(3)</c> for more details.</p>
<p>Own Id: OTP-4695</p>
</item>
<item>
<p>Added functions <c>cover:compile_beam/1</c> and
<c>cover:compile_beam_directory/0,1</c>. These functions use
abstract code from existing beam files when cover compiling.</p>
<p>Added option <c>html</c> to
<c>cover:analyse_to_file/1,2,3</c>. Instead of plain text,
a HTML file is generated with all uncovered lines colored
red.</p>
<p>Added functions <c>cover:export/1,2</c> and
<c>cover:import/1</c>. These functions can be used to export
current coverage data to a file, and then import the data
in a later session. Data can be exported for one single
module or for all currently cover compiled modules.</p>
<p>Own Id: OTP-4702</p>
</item>
<item>
<p>Erlang mode for Emacs: Added function
<c>erlang-align-arrows</c>.</p>
<p>Own Id: OTP-4737</p>
</item>
<item>
<p>The interface for the <c>instrument</c> module has been
slightly changed. Also some new functionality has been
added. See <c>instrument(3)</c> for more information.</p>
