<p>This module provides the parse transformation that makes calls to
<span class="bold_code bc-19"><a href="ets.html"><span class="code">ets</span></a></span> and
<span class="bold_code bc-13"><a href="javascript:erlhref('../../../../doc/../','runtime_tools','dbg.html#fun2ms-1');"><span class="code">dbg:fun2ms/1</span></a></span>
translate into literal match specifications. It also provides the back end
for the same functions when called from the Erlang shell.</p>
<p>The translation from funs to match specifications
is accessed through the two "pseudo functions"
<span class="bold_code bc-15"><a href="ets.html#fun2ms-1"><span class="code">ets:fun2ms/1</span></a></span> and
<span class="bold_code bc-13"><a href="javascript:erlhref('../../../../doc/../','runtime_tools','dbg.html#fun2ms-1');"><span class="code">dbg:fun2ms/1</span></a></span>.</p>
<p>As everyone trying to use
<span class="bold_code bc-15"><a href="ets.html#select-1"><span class="code">ets:select/2</span></a></span> or
<span class="bold_code bc-18"><a href="javascript:erlhref('../../../../doc/../','runtime_tools','dbg.html');"><span class="code">dbg</span></a></span> seems to end up
reading this manual page, this description is an introduction to the
concept of match specifications.</p>
<p>Read the whole manual page if it is the first time you are using
the transformations.</p>
<p>Match specifications are used more or less as filters. They resemble
usual Erlang matching in a list comprehension or in a fun used with
<span class="bold_code bc-15"><a href="lists.html#foldl-3"><span class="code">lists:foldl/3</span></a></span>, and so on.
However, the syntax of pure match specifications is awkward, as
they are made up purely by Erlang terms, and the language has no
syntax to make the match specifications more readable.</p>
<p>As the execution and structure of the match specifications are like
that of a fun, it is more straightforward
to write it using the familiar fun syntax and to have that
translated into a match specification automatically. A real fun is
clearly more powerful than the match specifications allow, but bearing
the match specifications in mind, and what they can do, it is still
more convenient to write it all as a fun. This module contains the
code that translates the fun syntax into match specification
terms.</p>

<div class="REFBODY rb-3">
<p>Using <span class="bold_code bc-15"><a href="ets.html#select-2"><span class="code">ets:select/2</span></a></span>
and a match specification, one can filter out rows of
a table and construct a list of tuples containing relevant parts
of the data in these rows.
One can use <span class="bold_code bc-15"><a href="ets.html#foldl-3"><span class="code">ets:foldl/3</span></a></span>
instead, but the <span class="code">ets:select/2</span> call is far more efficient.
Without the translation provided by <span class="code">ms_transform</span>,
one must struggle with writing match specifications terms
to accommodate this.</p>
<p>Consider a simple table of employees:</p>
<div class="example"><pre>-record(emp, {empno, %Employee number as a string, the key
surname, %Surname of the employee
givenname, %Given name of employee
dept, %Department, one of {dev,sales,prod,adm}
empyear}). %Year the employee was employed</pre></div>
<p>We create the table using:</p>
<div class="example"><pre>ets:new(emp_tab, [{keypos,#emp.empno},named_table,ordered_set]).</pre></div>
<p>We fill the table with randomly chosen data:</p>
<div class="example"><pre>[{emp,"011103","Black","Alfred",sales,2000},
{emp,"041231","Doe","John",prod,2001},
{emp,"052341","Smith","John",dev,1997},
{emp,"076324","Smith","Ella",sales,1995},
{emp,"122334","Weston","Anna",prod,2002},
{emp,"535216","Chalker","Samuel",adm,1998},
{emp,"789789","Harrysson","Joe",adm,1996},
{emp,"963721","Scott","Juliana",dev,2003},
{emp,"989891","Brown","Gabriel",prod,1999}]</pre></div>
<p>Assuming that we want the employee numbers of everyone in the sales
department, there are several ways.</p>
<p><span class="code">ets:match/2</span> can be used:</p>
<div class="example"><pre>
1> <span class="bold_code bc-12">ets:match(emp_tab, {'_', '$1', '_', '_', sales, '_'}).</span>
[["011103"],["076324"]]</pre></div>
<p><span class="code">ets:match/2</span> uses a simpler type of match specification,
but it is still unreadable, and one has little control over the
returned result. It is always a list of lists.</p>
<p><span class="bold_code bc-15"><a href="ets.html#foldl-3"><span class="code">ets:foldl/3</span></a></span> or
<span class="bold_code bc-15"><a href="ets.html#foldr-3"><span class="code">ets:foldr/3</span></a></span> can be used to avoid the nested lists:</p>
<div class="example"><pre>ets:foldr(fun(#emp{empno = E, dept = sales},Acc) -> [E | Acc];
(_,Acc) -> Acc
end,
[],
emp_tab).</pre></div>
<p>The result is <span class="code">["011103","076324"]</span>. The fun is
straightforward, so the only problem is that all the data from the
table must be transferred from the table to the calling process for
filtering. That is inefficient compared to the <span class="code">ets:match/2</span>
call where the filtering can be done "inside" the emulator and only
the result is transferred to the process.</p>
<p>Consider a "pure" <span class="code">ets:select/2</span> call that does what
<span class="code">ets:foldr</span> does:</p>
<div class="example"><pre>ets:select(emp_tab, [{#emp{empno = '$1', dept = sales, _='_'},[],['$1']}]).</pre></div>
<p>Although the record syntax is used, it is still hard to
read and even harder to write. The first element of the tuple,
<span class="code">#emp{empno = '$1', dept = sales, _='_'}</span>, tells what to
match. Elements not matching this are not returned, as in
the <span class="code">ets:match/2</span> example. The second element, the empty list,
is a list of guard expressions, which we do not need. The third
element is the list of expressions constructing the return value (in
ETS this is almost always a list containing one single term).
In our case <span class="code">'$1'</span> is bound to the employee number in the head
(first element of the tuple), and hence the employee number is
returned. The result is <span class="code">["011103","076324"]</span>, as in
the <span class="code">ets:foldr/3</span> example, but the result is retrieved much
more efficiently in terms of execution speed and
memory consumption.</p>
<p>Using <span class="code">ets:fun2ms/1</span>, we can combine the ease of use of
the <span class="code">ets:foldr/3</span> and the efficiency of the pure
<span class="code">ets:select/2</span> example:</p>
<div class="example"><pre>-include_lib("stdlib/include/ms_transform.hrl").
ets:select(emp_tab, ets:fun2ms(
fun(#emp{empno = E, dept = sales}) ->
E
end)).</pre></div>
<p>This example requires no special knowledge of match
specifications to understand. The head of the fun matches what
you want to filter out and the body returns what you want
returned. As long as the fun can be kept within the limits of the
match specifications, there is no need to transfer all table data
to the process for filtering as in the <span class="code">ets:foldr/3</span>
example. It is easier to read than the <span class="code">ets:foldr/3</span> example,
as the select call in itself discards anything that does not
match, while the fun of the <span class="code">ets:foldr/3</span> call needs to
handle both the elements matching and the ones not matching.</p>
<p>In the <span class="code">ets:fun2ms/1</span> example above, it is needed to
include <span class="code">ms_transform.hrl</span> in the source code, as this is
what triggers the parse transformation of the <span class="code">ets:fun2ms/1</span>
call to a valid match specification. This also implies that the
transformation is done at compile time (except when called from
the shell) and therefore takes no resources in runtime. That is,
although you use the more intuitive fun syntax, it gets as
efficient in runtime as writing match specifications by hand.</p>

<p>Assume that we want to get all the employee numbers of employees
hired before year 2000. Using <span class="code">ets:match/2</span> is not
an alternative here, as relational operators cannot be
expressed there.
Once again, <span class="code">ets:foldr/3</span> can do it (slowly, but correct):</p>
<div class="example"><pre>ets:foldr(fun(#emp{empno = E, empyear = Y},Acc) when Y < 2000 -> [E | Acc];

end,

<p>The result is <span class="code">["052341","076324","535216","789789","989891"]</span>,
as expected. The equivalent expression using a handwritten match
specification would look like this:</p>
<div class="example"><pre>ets:select(emp_tab, [{#emp{empno = '$1', empyear = '$2', _='_'},
[{'<', '$2', 2000}],
['$1']}]). </pre></div>
<p>This gives the same result. <span class="code">[{'<', '$2', 2000}]</span> is in
the guard part and therefore discards anything that does not have an
<span class="code">empyear</span> (bound to <span class="code">'$2'</span> in the head) less than 2000, as
the guard in the <span class="code">foldr/3</span> example.</p>

<p>Assume that we want the whole object matching instead of only one
element. One alternative is to assign a variable to every part
of the record and build it up once again in the body of the fun, but
the following is easier:</p>

<p>As in ordinary Erlang matching, you can bind a variable to the
whole matched object using a "match inside the match", that is, a
<span class="code">=</span>. Unfortunately in funs translated to match specifications,
it is allowed only at the "top-level", that is,
matching the <strong>whole</strong> object arriving to be matched
into a separate variable.
If you are used to writing match specifications by hand, we
mention that variable A is simply translated into '$_'.
Alternatively, pseudo function <span class="code">object/0</span>
also returns the whole matched object, see section

<div class="REFBODY rb-3">
<p>What more can you do? A simple answer is: see the documentation of
<span class="bold_code bc-18"><a href="javascript:erlhref('../../../../doc/../','erts','match_spec.html');">match specifications</a></span>
in ERTS User's Guide.
However, the following is a brief overview of the most useful "built-in
functions" that you can use when the fun is to be translated into a match
specification by
<span class="bold_code bc-15"><a href="ets.html#fun2ms-1"><span class="code">ets:fun2ms/1</span></a></span>. It is not
possible to call other functions than those allowed in match
specifications. No "usual" Erlang code can be executed by the fun that
is translated by <span class="code">ets:fun2ms/1</span>. The fun is limited
exactly to the power of the match specifications, which is
unfortunate, but the price one must pay for the execution speed of
<span class="code">ets:select/2</span> compared to <span class="code">ets:foldl/foldr</span>.</p>
<p>The head of the fun is a head matching (or mismatching)
<strong>one</strong> parameter, one object of the table we select
from. The object is always a single variable (can be <span class="code">_</span>) or
a tuple, as ETS, Dets, and Mnesia tables include
that. The match specification returned by <span class="code">ets:fun2ms/1</span> can
be used with <span class="code">dets:select/2</span> and <span class="code">mnesia:select/2</span>, and
with <span class="code">ets:select/2</span>. The use of <span class="code">=</span> in the head
is allowed (and encouraged) at the top-level.</p>
<p>The guard section can contain any guard expression of Erlang.
The following is a list of BIFs and expressions:</p>
<ul>
<li>
<p>Type tests: <span class="code">is_atom</span>, <span class="code">is_float</span>, <span class="code">is_integer</span>,
<span class="code">is_list</span>, <span class="code">is_number</span>, <span class="code">is_pid</span>, <span class="code">is_port</span>,
<span class="code">is_reference</span>, <span class="code">is_tuple</span>, <span class="code">is_binary</span>,
<span class="code">is_function</span>, <span class="code">is_record</span></p>
</li>
<li>
<p>Boolean operators: <span class="code">not</span>, <span class="code">and</span>, <span class="code">or</span>,
<span class="code">andalso</span>, <span class="code">orelse</span></p>
</li>
<li>
<p>Relational operators: >, >=, <, =<, =:=, ==, =/=, /=</p>
</li>
<li>
<p>Arithmetics: <span class="code">+</span>, <span class="code">-</span>, <span class="code">*</span>,
<span class="code">div</span>, <span class="code">rem</span></p>
</li>
<li>
<p>Bitwise operators: <span class="code">band</span>, <span class="code">bor</span>, <span class="code">bxor</span>, <span class="code">bnot</span>,
<span class="code">bsl</span>, <span class="code">bsr</span></p>
</li>
<li>
<p>The guard BIFs: <span class="code">abs</span>, <span class="code">element</span>,
<span class="code">hd</span>, <span class="code">length</span>,
<span class="code">node</span>, <span class="code">round</span>, <span class="code">size</span>, <span class="code">tl</span>, <span class="code">trunc</span>,
<span class="code">self</span></p>
</li>
</ul>
<p>Contrary to the fact with "handwritten" match specifications, the
<span class="code">is_record</span> guard works as in ordinary Erlang code.</p>
<p>Semicolons (<span class="code">;</span>) in guards are allowed, the result is (as
expected) one "match specification clause" for each semicolon-separated
part of the guard. The semantics is identical to the Erlang
semantics.</p>
<p>The body of the fun is used to construct the
resulting value. When selecting from tables, one usually construct
a suiting term here, using ordinary Erlang term construction, like
tuple parentheses, list brackets, and variables matched out in the
head, possibly with the occasional constant. Whatever
expressions are allowed in guards are also allowed here, but no special
functions exist except <span class="code">object</span> and
<span class="code">bindings</span> (see further down), which returns the whole
matched object and all known variable bindings, respectively.</p>
<p>The <span class="code">dbg</span> variants of match specifications have an
imperative approach to the match specification body, the ETS
dialect has not. The fun body for <span class="code">ets:fun2ms/1</span> returns the result
without side effects. As matching (<span class="code">=</span>) in the body of
the match specifications is not allowed (for performance reasons) the
only thing left, more or less, is term construction.</p>

<div class="REFBODY rb-3">
<p>This section describes the slightly different match specifications
translated by <span class="bold_code bc-13"><a href="javascript:erlhref('../../../../doc/../','runtime_tools','dbg.html#fun2ms-1');"><span class="code">dbg:fun2ms/1</span></a></span>.</p>
<p>The same reasons for using the parse transformation apply to
<span class="code">dbg</span>, maybe even more, as filtering using Erlang code is
not a good idea when tracing (except afterwards, if you trace
to file). The concept is similar to that of <span class="code">ets:fun2ms/1</span>
except that you usually use it directly from the shell
(which can also be done with <span class="code">ets:fun2ms/1</span>).</p>
<p>The following is an example module to trace on:</p>
<div class="example"><pre>-module(toy).
-export([start/1, store/2, retrieve/1]).
start(Args) ->
toy_table = ets:new(toy_table, Args).
store(Key, Value) ->
ets:insert(toy_table, {Key,Value}).
retrieve(Key) ->
[{Key, Value}] = ets:lookup(toy_table, Key),
Value.</pre></div>
<p>During model testing, the first test results in
<span class="code">{badmatch,16}</span> in <span class="code">{toy,start,1}</span>, why?</p>
<p>We suspect the <span class="code">ets:new/2</span> call, as we match hard on the
return value, but want only the particular <span class="code">new/2</span> call with
<span class="code">toy_table</span> as first parameter. So we start a default tracer
on the node:</p>
<div class="example"><pre>
1> <span class="bold_code bc-12">dbg:tracer().</span>
{ok,<0.88.0>}</pre></div>
<p>We turn on call tracing for all processes, we want to
make a pretty restrictive trace pattern, so there is no need to call
trace only a few processes (usually it is not):</p>
<div class="example"><pre>
2> <span class="bold_code bc-12">dbg:p(all,call).</span>
{ok,[{matched,nonode@nohost,25}]}</pre></div>
<p>We specify the filter, we want to view calls that resemble
<span class="code">ets:new(toy_table, <something>)</span>:</p>
<div class="example"><pre>
3> <span class="bold_code bc-12">dbg:tp(ets,new,dbg:fun2ms(fun([toy_table,_]) -> true end)).</span>
{ok,[{matched,nonode@nohost,1},{saved,1}]}</pre></div>
<p>As can be seen, the fun used with
<span class="code">dbg:fun2ms/1</span> takes a single list as parameter instead of a
single tuple. The list matches a list of the parameters to the traced
function. A single variable can also be used. The body
of the fun expresses, in a more imperative way, actions to be taken if
the fun head (and the guards) matches. <span class="code">true</span> is returned here,
only because the body of a fun cannot be empty. The return value
is discarded.</p>
<p>The following trace output is received during test:</p>
<div class="example"><pre>(<0.86.0>) call ets:new(toy_table, [ordered_set]) </pre></div>
<p>Assume that we have not found the problem yet, and want to see what
<span class="code">ets:new/2</span> returns. We use a slightly different trace pattern:</p>
<div class="example"><pre>
4> <span class="bold_code bc-12">dbg:tp(ets,new,dbg:fun2ms(fun([toy_table,_]) -> return_trace() end)).</span></pre></div>
<p>The following trace output is received during test:</p>
<div class="example"><pre>(<0.86.0>) call ets:new(toy_table,[ordered_set])
(<0.86.0>) returned from ets:new/2 -> 24 </pre></div>
<p>The call to <span class="code">return_trace</span> results in a trace message
when the function returns. It applies only to the specific function call
triggering the match specification (and matching the head/guards of
the match specification). This is by far the most common call in the
body of a <span class="code">dbg</span> match specification.</p>
<p>The test now fails with <span class="code">{badmatch,24}</span> because the atom
<span class="code">toy_table</span> does not match the number returned for an unnamed table.
So, the problem is found, the table is to be named, and the arguments
supplied by the test program do not include <span class="code">named_table</span>. We
rewrite the start function:</p>
<div class="example"><pre>start(Args) ->
toy_table = ets:new(toy_table, [named_table|Args]).</pre></div>
<p>With the same tracing turned on, the following trace output is
received:</p>
<div class="example"><pre>(<0.86.0>) call ets:new(toy_table,[named_table,ordered_set])
(<0.86.0>) returned from ets:new/2 -> toy_table </pre></div>
<p>Assume that the module now passes all testing and goes into
the system. After a while, it is found that table
<span class="code">toy_table</span> grows while the system is running and that
there are many elements with atoms as keys. We expected
only integer keys and so does the rest of the system, but
clearly not the entire system. We turn on call tracing and try to
see calls to the module with an atom as the key:</p>
<div class="example"><pre>
1> <span class="bold_code bc-12">dbg:tracer().</span>
{ok,<0.88.0>}
2> <span class="bold_code bc-12">dbg:p(all,call).</span>
{ok,[{matched,nonode@nohost,25}]}
3> <span class="bold_code bc-12">dbg:tpl(toy,store,dbg:fun2ms(fun([A,_]) when is_atom(A) -> true end)).</span>
{ok,[{matched,nonode@nohost,1},{saved,1}]}</pre></div>
<p>We use <span class="code">dbg:tpl/3</span> to ensure to catch local calls
(assume that the module has grown since the smaller version and we are
unsure if this inserting of atoms is not done locally). When in
doubt, always use local call tracing.</p>
<p>Assume that nothing happens when tracing in this way. The function
is never called with these parameters. We conclude that
someone else (some other module) is doing it and realize that we
must trace on <span class="code">ets:insert/2</span> and want to see the calling function.
The calling function can be retrieved using the match specification
function <span class="code">caller</span>. To get it into the trace message, the match
specification function <span class="code">message</span> must be used. The filter
call looks like this (looking for calls to <span class="code">ets:insert/2</span>):</p>
<div class="example"><pre>
4> <span class="bold_code bc-12">dbg:tpl(ets,insert,dbg:fun2ms(fun([toy_table,{A,_}]) when is_atom(A) -> </span>
<span class="bold_code bc-12"> message(caller()) </span>
<span class="bold_code bc-12"> end)). </span>
{ok,[{matched,nonode@nohost,1},{saved,2}]}</pre></div>
<p>The caller is now displayed in the "additional message" part of the
trace output, and the following is displayed after a while:</p>
<div class="example"><pre>(<0.86.0>) call ets:insert(toy_table,{garbage,can}) ({evil_mod,evil_fun,2}) </pre></div>
<p>You have realized that function <span class="code">evil_fun</span> of the
<span class="code">evil_mod</span> module, with arity <span class="code">2</span>, is causing all this trouble.
</p>
<p>This example illustrates the most used calls in match specifications for
<span class="code">dbg</span>. The other, more esoteric, calls are listed and explained in
<span class="bold_code bc-18"><a href="javascript:erlhref('../../../../doc/../','erts','match_spec.html');">Match specifications in Erlang</a></span>

<div class="REFBODY rb-3">
<a name="warnings_and_restrictions"></a>
<p>The following warnings and restrictions apply to the funs used in
with <span class="code">ets:fun2ms/1</span> and <span class="code">dbg:fun2ms/1</span>.</p>
<div class="warning">
<div class="label">Warning</div>
<div class="content"><p>
<p>To use the pseudo functions triggering the translation,
ensure to include the header file <span class="code">ms_transform.hrl</span>
in the source code. Failure to do so possibly results in
runtime errors rather than compile time, as the expression can
be valid as a plain Erlang program without translation.</p>
</p></div>
</div>
<div class="warning">
<div class="label">Warning</div>
<div class="content"><p>
<p>The fun must be literally constructed inside the
parameter list to the pseudo functions. The fun cannot
be bound to a variable first and then passed to
<span class="code">ets:fun2ms/1</span> or <span class="code">dbg:fun2ms/1</span>. For example,
<span class="code">ets:fun2ms(fun(A) -> A end)</span> works, but not
<span class="code">F = fun(A) -> A end, ets:fun2ms(F)</span>. The latter results
in a compile-time error if the header is included, otherwise a
runtime error.</p>
</p></div>
</div>
<p>Many restrictions apply to the fun that is translated into a match
specification. To put it simple: you cannot use anything in the fun
that you cannot use in a match specification. This means that,
among others, the following restrictions apply to the fun itself:</p>
<ul>
<li>
<p>Functions written in Erlang cannot be called, neither can
local functions, global functions, or real funs.</p>
</li>
<li>
<p>Everything that is written as a function call is translated
into a match specification call to a built-in function, so that
the call <span class="code">is_list(X)</span> is translated to <span class="code">{'is_list', '$1'}</span>
(<span class="code">'$1'</span> is only an example, the numbering can vary).
If one tries to call a function that is not a match specification
built-in, it causes an error.</p>
</li>
<li>
<p>Variables occurring in the head of the fun are replaced by
match specification variables in the order of occurrence, so
that fragment <span class="code">fun({A,B,C})</span> is replaced by
<span class="code">{'$1', '$2', '$3'}</span>, and so on. Every occurrence of such a
variable in the match specification is replaced by a match
specification variable in the same way, so that the fun
<span class="code">fun({A,B}) when is_atom(A) -> B end</span> is translated into
<span class="code">[{{'$1','$2'},[{is_atom,'$1'}],['$2']}]</span>.</p>
</li>
<li>
<p>Variables that are not included in the head are imported
from the environment and made into match specification
<span class="code">const</span> expressions. Example from the shell:</p>
<div class="example"><pre>
1> <span class="bold_code bc-12">X = 25.</span>
25
2> <span class="bold_code bc-12">ets:fun2ms(fun({A,B}) when A > X -> B end).</span>
[{{'$1','$2'},[{'>','$1',{const,25}}],['$2']}]</pre></div>
</li>
<li>
<p>Matching with <span class="code">=</span> cannot be used in the body. It can only
be used on the top-level in the head of the fun.
Example from the shell again:</p>
<div class="example"><pre>
1> <span class="bold_code bc-12">ets:fun2ms(fun({A,[B|C]} = D) when A > B -> D end).</span>
[{{'$1',['$2'|'$3']},[{'>','$1','$2'}],['$_']}]
2> <span class="bold_code bc-12">ets:fun2ms(fun({A,[B|C]=D}) when A > B -> D end).</span>
Error: fun with head matching ('=' in head) cannot be translated into
match_spec
{error,transform_error}
3> <span class="bold_code bc-12">ets:fun2ms(fun({A,[B|C]}) when A > B -> D = [B|C], D end).</span>
Error: fun with body matching ('=' in body) is illegal as match_spec
{error,transform_error}</pre></div>
<p>All variables are bound in the head of a match specification, so
the translator cannot allow multiple bindings. The special case
when matching is done on the top-level makes the variable bind
to <span class="code">'$_'</span> in the resulting match specification. It is to allow
a more natural access to the whole matched object. Pseudo
function <span class="code">object()</span> can be used instead, see below.</p>
<p>The following expressions are translated equally:</p>
<div class="example"><pre>ets:fun2ms(fun({a,_} = A) -> A end).
ets:fun2ms(fun({a,_}) -> object() end).</pre></div>
</li>
<li>
<p>The special match specification variables <span class="code">'$_'</span> and <span class="code">'$*'</span>
can be accessed through the pseudo functions <span class="code">object()</span>
(for <span class="code">'$_'</span>) and <span class="code">bindings()</span> (for <span class="code">'$*'</span>).
As an example, one can translate the following
<span class="code">ets:match_object/2</span> call to a <span class="code">ets:select/2</span> call:</p>
<div class="example"><pre>ets:match_object(Table, {'$1',test,'$2'}). </pre></div>
<p>This is the same as:</p>
<div class="example"><pre>ets:select(Table, ets:fun2ms(fun({A,test,B}) -> object() end)).</pre></div>
<p>In this simple case, the former
expression is probably preferable in terms of readability.</p>
<p>The <span class="code">ets:select/2</span> call conceptually looks like this
in the resulting code:</p>
<div class="example"><pre>ets:select(Table, [{{'$1',test,'$2'},[],['$_']}]).</pre></div>
<p>Matching on the top-level of the fun head can be a
more natural way to access <span class="code">'$_'</span>, see above.</p>
</li>
<li>
<p>Term constructions/literals are translated as much as is needed to
get them into valid match specification. This way tuples are made
into match specification tuple constructions (a one element tuple
containing the tuple) and constant expressions are used when
importing variables from the environment. Records are also
translated into plain tuple constructions, calls to element,
and so on. The guard test <span class="code">is_record/2</span> is translated into
match specification code using the three parameter version that is
built into match specification, so that <span class="code">is_record(A,t)</span> is
translated into <span class="code">{is_record,'$1',t,5}</span> if the record
size of record type <span class="code">t</span> is 5.</p>
</li>
<li>
<p>Language constructions such as <span class="code">case</span>, <span class="code">if</span>, and
<span class="code">catch</span> that are not present in match specifications are not
allowed.</p>
</li>
<li>
<p>If header file <span class="code">ms_transform.hrl</span> is not included,
the fun is not translated, which can result in a
<strong>runtime error</strong> (depending on whether the fun is
valid in a pure Erlang context).</p>
<p>Ensure that the header is included when using <span class="code">ets</span> and
<span class="code">dbg:fun2ms/1</span> in compiled code.</p>
</li>
<li>
<p>If pseudo function triggering the translation is
<span class="code">ets:fun2ms/1</span>, the head of the fun must contain a single
variable or a single tuple. If the pseudo function is
<span class="code">dbg:fun2ms/1</span>, the head of the fun must contain a single
variable or a single list.</p>
</li>
</ul>
<p>The translation from funs to match specifications is done at compile
time, so runtime performance is not affected by using these pseudo
functions.</p>
