|

<p>The original idea of passing two extra parameters to REPEAT, which makes it
|
|
||||||
possible to create preprocessor code on top of it, was due to Aleksey Gurtovoy.
|
|
||||||
The invokeable IDENTITY macro was also invented by him. He also suggested the
|
|
||||||
name for the library. Many thanks to Aleksey for his insights!</p>
|
|
||||||
<p>Thanks to everyone who participated in the review: David Abrahams, Beman Dawes,
|
|
||||||
Ronald Garcia, Douglas Gregor, Aleksey Gurtovoy, Jeremy Siek, and Daryle Walker.</p>
|
|
||||||
<p>Thanks to Chris Little and Mat Marcus for providing help with MWCW.</p>
|
|
||||||
<p>The original automatic recursion technique, which makes many of the library
|
|
||||||
primitives easier to use, was invented by Paul Mensonides.</p>
|
|
||||||
<p>The PREPROCESSOR library has been developed by Vesa Karvonen. </p>

<hr>
|
|
||||||
|
|
||||||
<p>Preprocessor metaprogramming is subject to heated discussions. Part of this is caused by
|
|
||||||
bad experiences with dangerous techniques, such as defining inline functions using macros. As a rule
|
|
||||||
of thumb, if you can find a clean and
|
|
||||||
manageable way to do something without using the preprocessor, then
|
|
||||||
you should do it that way.</p>
|
|
||||||
|
|
||||||
<p>Let's survey some of the widely known problems with the preprocessor in a problem/solution
|
|
||||||
format.</p>
|
|
||||||
<HR>
|
|
||||||
|
|
||||||
<p><B>PROBLEM:</B> Preprocessor does not
|
|
||||||
respect scope, therefore macros can accidentally and sometimes silently replace
|
|
||||||
code.</p>
|
|
||||||
|
|
||||||
<p><B>SOLUTION A:</B> Use all caps identifiers
|
|
||||||
for macros and only macros. This practically eliminates the possibility that a
|
|
||||||
macro might replace other kind of code accidentally.</p>
|
|
||||||
|
|
||||||
<p><B>SOLUTION B:</B> Use the Local Macro
|
|
||||||
idiom:</p>
|
|
||||||
|
|
||||||
<pre>#define MACRO ...
|
|
||||||
// Use MACRO
|
|
||||||
#undef MACRO
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>This makes sure that a macro can not accidentally
|
|
||||||
replace code outside of the scope of the local macro.</p>
|
|
||||||
<P>A problem with this solution is that the #undef can not be automated and may be
|
|
||||||
forgotten. Experienced programmers generally write the #undef either immediately
|
|
||||||
before (in time) or immediately after writing the macro definition.</P>
|
|
||||||
<P><B>SOLUTION C:</B> Use the Unique Macro Prefix idiom:</P>
|
|
||||||
|
|
||||||
<pre>#define UMP_MACRO
|
|
||||||
// Use UMP_MACRO
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
|
|
||||||
<P>This makes accidental substitution and collisions highly
|
|
||||||
unlikely. Problems with this solution:</P>
|
|
||||||
<UL>
|
|
||||||
<LI>
|
|
||||||
There can still be naming collisions inside a large project.
|
|
||||||
<LI>
|
|
||||||
Macros still pollute the global namespace. </LI></UL>
|
|
||||||
<P><EM><B>By combining all solutions, whenever
|
|
||||||
possible, the scope problem can be largely avoided.</B></EM></P>
|
|
||||||
<HR>
|
|
||||||
|
|
||||||
<P><B>PROBLEM:</B> Preprocessor code is difficult to read.
|
|
||||||
It requires understanding the basic process of how
|
|
||||||
the preprocessor recursively expands macros, finding the macro definition and mentally
|
|
||||||
substituting the parameters of the macro. </P>
|
|
||||||
<P><B>SOLUTION:</B> Any kind of programming requires basic understanding
|
|
||||||
of how the code is executed. Any parameterization technique, including simple
|
|
||||||
functions and templates requires finding the definition and mentally substituting
|
|
||||||
parameters. </P>
|
|
||||||
<P>However, it is good to know a few techniques:</P>
|
|
||||||
<UL>
|
|
||||||
<LI>
|
|
||||||
By using as many Local Macros as reasonable, the bulk of the searching
|
|
||||||
process can be eliminated.
|
|
||||||
<LI>
|
|
||||||
Code browsers and text search tools make it easier to find the
|
|
||||||
definitions.
|
|
||||||
<LI>
|
|
||||||
The compiler can be used for generating the preprocessed source code in
|
|
||||||
order to look for bugs.
|
|
||||||
<LI>
|
|
||||||
Before turning something into a preprocessor metaprogram, first
|
|
||||||
implement a small scale version of it without preprocessor. Then work
|
|
||||||
bottom->up replacing hand written constructs by using preprocessor. This
|
|
||||||
way you can test the code incrementally. Experienced programmers often skip
|
|
||||||
many stages, but if something proves too complex to write directly, it is
|
|
||||||
always possible to fall back to incremental methods.
|
|
||||||
<LI>
|
|
||||||
If you insert a special symbol into the preprocessor code in places where
|
|
||||||
there should be a line break, you can make code readable after preprocessing
|
|
||||||
simply by using a search and replace tool. </LI></UL>
|
|
||||||
<P><B><EM> An especially important thing to remember is to limit the use of preprocessor
|
|
||||||
to the structured, well understood and safe methods. Structure helps to understand
|
|
||||||
complex systems <A href="bibliography.htm#[McConnell]">[McConnell]</A>.</EM></B></P>

<h3><a name="Metrowerks Codewarrior 7.0">Metrowerks Codewarrior 7.0</a></h3>
|
|
||||||
<p>Metrowerks Codewarrior 7.0 has a bug in preprocessor (to be more
|
|
||||||
concrete, in function-like macro replacement mechanism) that restricts usage
|
|
||||||
of the library to only very simple cases, at least if you don't write code that
|
|
||||||
specifically address this issue; for example, the above NUMBERED_EXPRESSION
|
|
||||||
example doesn't compile on CW 7.0. Below is a simple test case that reproduces
|
|
||||||
the bug:</p>
|
|
||||||
|
|
||||||
<pre>#define IDENTITY_MACRO(x) IDENTITY_MACRO_BODY(x)
|
|
||||||
#define IDENTITY_MACRO_BODY(x) x
|
|
||||||
#define COMMA_TOKEN() ,
|
|
||||||
int a IDENTITY_MACRO(COMMA_TOKEN)() b; // this works
|
|
||||||
int c IDENTITY_MACRO(IDENTITY_MACRO(COMMA_TOKEN))() d; // this doesn't
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>Basically, what's happening here is that function-like COMMA_TOKEN macro gets
|
|
||||||
expanded _inside_ of the nested IDENTITY_MACRO call - even although it's NOT
|
|
||||||
followed by a '(' as the next preprocessing token - which is a clearly an incorrect
|
|
||||||
behavior (see 16.3 [cpp.replace] para 9 for the detailed description of the
|
|
||||||
function-like macro replacement process). I've submitted a bug report, but they
|
|
||||||
haven't confirmed it yet.</p>
|
|
||||||
<p>So, this is not a problem of the library, but probably something that needs
|
|
||||||
to be mentioned in the documentation, may be with some examples of how to workaround
|
|
||||||
the issue. Just to show one possible way around the problem, here is a NUMBERED_EXPRESSION
|
|
||||||
macro that does work on MWCW:</p>
|
|
||||||
<pre>#define NUMBERED_EXPRESSION(n, x) \
|
|
||||||
BOOST_PP_CAT(BOOST_, \
|
|
||||||
BOOST_PP_IF( \
|
|
||||||
n \
|
|
||||||
, PREPROCESSOR_IDENTITY(x##n) \
|
|
||||||
, PREPROCESSOR_EMPTY \
|
|
||||||
))() \
|

||||||

|
|
||||||
<p>It appears that their algorithm of macro call invocation is quite far
|
|
||||||
from ideal, because for the following code fragment (which is a part of
|
|
||||||
<a href="../test/preprocessor_test.cpp">preprocessor_test.cpp</a>), the
|
|
||||||
linear increasing of IS_FUNCTION_HELPER_TEST_MAX value leads to not even
|
|
||||||
quadratic, but something like exponential increasing of compilation time!
|
|
||||||
(see the timing data below). This behavior may or may not be problematic
|
|
||||||
for you, depending on how intense is your usage of the library.
|
|
||||||
|
|
||||||

<h3>Legend</h3>
|
|
||||||
<ul>
|
|
||||||
<li><b>STATE</b> is the current state of iteration. The state is usually a tuple.</li>
|
|
||||||
<li><b>PRED</b> is the condition for iteration. It must expand to a decimal
|
|
||||||
integer literal.</li>
|
|
||||||
<li><b>OP</b> is the iterated macro. Note that if the state is a tuple, then
|
|
||||||
OP(R,STATE) usually expands to a tuple of the same number of elements.</li>
|
|
||||||
<li><b>MACRO</b> is the state instantiation macro.</li>
|
|
||||||
<li><b>R</b> is the recursion depth and should only be used as a parameter to
|
|
||||||
other macros using <a href="for.htm#BOOST_PP_FOR">BOOST_PP_FOR</a>() or for invoking <a href="for.htm#BOOST_PP_FOR">BOOST_PP_FOR</a>##R()
|
|
||||||
directly. For each macro using <a href="for.htm#BOOST_PP_FOR">BOOST_PP_FOR</a>(), e.g. <a href="list_for_each.htm#BOOST_PP_LIST_FOR_EACH">BOOST_PP_LIST_FOR_EACH</a>(),
|
|
||||||
there is a version of the macro, e.g. <a href="list_for_each.htm#BOOST_PP_LIST_FOR_EACH_R">BOOST_PP_LIST_FOR_EACH_R</a>(), distinguished
|
|
||||||
by the R suffix, that accepts an additional recursion depth as the first
|
|
||||||
parameter. This technique is necessary to avoid recursively expanding the same
|
|
||||||
macro again, which is not permitted by the C++ preprocessor.</li>
|
|
||||||
</ul>
|
|
||||||
|
|
||||||
<h3><a href="repeat.htm#BOOST_PP_REPEAT">BOOST_PP_REPEAT</a>() vs <a href="for.htm#BOOST_PP_FOR">BOOST_PP_FOR</a>()</h3>
|
|
||||||
|
|
||||||
<p><a href="for.htm#BOOST_PP_FOR">BOOST_PP_FOR</a>() is a generalization of <a href="repeat.htm#BOOST_PP_REPEAT">BOOST_PP_REPEAT</a>(). This means that
|
|
||||||
<a href="repeat.htm#BOOST_PP_REPEAT">BOOST_PP_REPEAT</a>() can be implemented using <a href="for.htm#BOOST_PP_FOR">BOOST_PP_FOR</a>(). However,
|
|
||||||
<a href="repeat.htm#BOOST_PP_REPEAT">BOOST_PP_REPEAT</a>() was introduced earlier, is generally easier to use, and is
|
|
||||||
still quite useful on its own.</p>
|
|
||||||
|
|
||||||
<h3>2D and 3D repetition</h3>
|
|
||||||
|
|
||||||
<p><a href="for.htm#BOOST_PP_FOR">BOOST_PP_FOR</a>() can be used for multidimensional repetition simply by
|
|
||||||
invoking <a href="for.htm#BOOST_PP_FOR">BOOST_PP_FOR</a>##R() directly.</p>
|
|
||||||
|
|
||||||
<h3>Automatic recursion?</h3>
|
|
||||||
|
|
||||||
<p><a href="for.htm#BOOST_PP_FOR">BOOST_PP_FOR</a>() currently does not implement automatic recursion. The reason
|
|
||||||
for this is that it would lead to very poor performance. The automatic recursion
|
|
||||||
technique takes O(N) steps just to find out that the Nth recursion should be used.
|
|
||||||
This would dramatically effect the time complexity of macros using automatic
|
|
||||||
recursion.</p>

<p>A list is an arbitrary size collection of elements.</p>
|
|
||||||
|
|
||||||
<p>In the preprocessor library, the internal representation of lists
|
|
||||||
uses parts that are like macro parameter lists. Thus an element of a list
|
|
||||||
can be any sequence of tokens that constitutes a single macro parameter.</p>
|
|
||||||
|
|
||||||
<p>Lists are manipulated using both list ADT macros and higher-order macros. For an introduction to manipulation of lists in functional programming, see

|
|

<p>A tuple is a fixed size collection of elements.</p>
|
|
||||||
|
|
||||||
<p>In the preprocessor library, tuples are represented like macro parameter
|
|
||||||
lists. Thus an element of a tuple can be any sequence of tokens that
|
|
||||||
constitutes a single macro parameter.</p>
|
|
||||||
|
|
||||||
<p>Examples of tuples:</p>
|
|
||||||
|
|
||||||
<pre>
|
|
||||||
(const, volatile) // 2-tuple
|
|
||||||
(*, /, %) // 3-tuple
|
|
||||||
(1, "2", '3', (4,5)) // 4-tuple
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<p>Tuples can be used for representing structured data.</p>

</pre>
|

||||||

|
||||||
<h3>Legend</h3>
|
|
||||||
<ul>
|
|
||||||
<li><b>STATE</b> is the current state of iteration. The state is usually a tuple.</li>
|
|
||||||
<li><b>PRED</b> is the condition for iteration. It must expand to a decimal
|
|
||||||
integer literal.</li>
|
|
||||||
<li><b>OP</b> is the iterated macro. Note that if the state is a tuple, then
|
|
||||||
OP(D,STATE) usually expands to a tuple of the same number of elements.</li>
|
|
||||||
<li><b>D</b> is the recursion depth and should only be used as a parameter
|
|
||||||
to other macros using <a href="while.htm#BOOST_PP_WHILE">BOOST_PP_WHILE</a>(). Such macros include
|
|
||||||
<a href="arithmetic_add.htm#BOOST_PP_ADD">BOOST_PP_ADD</a>() and other arithmetic operations. For each macro using
|
|
||||||
<a href="while.htm#BOOST_PP_WHILE">BOOST_PP_WHILE</a>(), there is a version of the macro, distinguished by the
|
|
||||||
D suffix (e.g. <a href="arithmetic_add.htm#BOOST_PP_ADD_D">BOOST_PP_ADD_D</a>()), that accepts an additional recursion
|
|
||||||
depth as the first parameter. This technique is necessary to avoid
|
|
||||||
recursively expanding the same macro again, which is not permitted by the
|
|
||||||
C++ preprocessor.</li>
|
|
||||||
</ul>
|
|
||||||
|
|
||||||
<h3>Automatic recursion?</h3>
|
|
||||||
|
|
||||||
<p><a href="while.htm#BOOST_PP_WHILE">BOOST_PP_WHILE</a>() currently does not implement automatic recursion. The reason
|
|
||||||
for this is that it would lead to very poor performance. The automatic recursion
|
|
||||||
technique takes O(N) steps just to find out that the Nth recursion should be used.
|
|
||||||
This would dramatically effect the time complexity of macros using automatic
|
|
||||||
recursion.</p>
|
|
||||||
|
|
||||||
<h3>Note</h3>
|
|
||||||
<ul>
|
|
||||||
<li>The value of the D parameter may exceed <a href="limits.htm#BOOST_PP_LIMIT_MAG">BOOST_PP_LIMIT_MAG</a>.</li>
|
|
||||||
<li>Using <a href="while.htm#BOOST_PP_WHILE">BOOST_PP_WHILE</a>() is a bit tricky. This is due to the C++
|
|
||||||
preprocessor limitations. It is recommended to take a look at the
|
|
||||||
implementations of the various PREPROCESSOR library primitives
|
|
||||||
such as <a href="arithmetic_add.htm#BOOST_PP_ADD">BOOST_PP_ADD</a>() for additional examples.</li>
|
|
||||||
</ul>

<h2><a name="Motivation">Motivation</a></h2>
|
|
||||||
|
|
||||||
<p>The C++ function and template parameter lists are special syntactic constructs
|
|
||||||
and it is impossible to directly manipulate or generate them using C++ constructs.
|
|
||||||
This leads to unnecessary code repetition.</p>
|
|
||||||
<p> Consider the implementation of the is_function<> metafunction in Boost. The
|
|
||||||
implementation uses an overloaded is_function_tester() function that is used
|
|
||||||
for testing if a type is convertible to pointer to a function. Because of the
|
|
||||||
special treatment of parameter lists, it is not possible to directly match a
|
|
||||||
function with an arbitrary parameter list. Instead, the is_function_tester()
|
|
||||||
must be overloaded for every distinct number of parameters that is to be supported.
|
|
||||||
Example:</p>
|
|
||||||
|
|
||||||
<pre>template <class R>
|
|
||||||
yes_type is_function_tester(R (*)());
|
|
||||||
template <class R, class A0>
|
|
||||||
yes_type is_function_tester(R (*)(A0));
|
|
||||||
template <class R, class A0, A1>
|
|
||||||
yes_type is_function_tester(R (*)(A0, A1));
|
|
||||||
template <class R, class A0, A1, A2>
|
|
||||||
yes_type is_function_tester(R (*)(A0, A1, A2));
|
|
||||||
|
|
||||||
// ...
|
|
||||||
</pre>
|
|
||||||
|
|
||||||
<P>The need for this kind of repetition occurs particularly frequently while implementing
|
|
||||||
generic components or metaprogramming facilities, but the need also manifests
|
|
||||||
itself in many far simpler situations. </P>
|
|
||||||
|
|
||||||
<h3>Typical solutions</h3>
|
|
||||||
|
|
||||||
<p>Typically the repetition is done manually. Manual code repetition is highly
|
|
||||||
unproductive, but sometimes more readable to the untrained eye.</p>
|
|
||||||
<p>Another solution is to write an external program for generating the repeated
|
|
||||||
code or use some other extra linquistic means such as a smart editor. Unfortunately,
|
|
||||||
using external code generators has many disadvantages:</p>
|
|
||||||
<ul>
|
|
||||||
<li>writing the generator takes time (this could be helped by using a standard
|
|
||||||
generator)</li>
|
|
||||||
<li>it is no longer productive to manipulate C++ code directly</li>
|
|
||||||
<li>invoking the generator may be difficult</li>
|
|
||||||
<li>automating the invocation of the generator can be difficult in certain environments
|
|
||||||
(automatic invocation is desirable for active libraries)</li>
|
|
||||||
<li>porting and distributing the generator may be difficult or simply takes
|
|
||||||
precious time</li>
|
|
||||||
</ul>
|
|
||||||
<h3>What about the preprocessor?</h3>
|
|
||||||
<p>Because C++ comes with a preprocessor, one would assume that it would support
|
|
||||||
these kind of needs directly. Using the preprocessor in this case is highly
|
|
||||||
desirable because:</p>
|
|
||||||
<ul>
|
|
||||||
<li>preprocessor is highly portable</li>
|
|
||||||
<li>preprocessor is automatically invoked as part of the compiling process</li>
|
|
||||||
<li>preprocessor metacode can be directly embedded into the C++ source code</li>
|
|
||||||
<li>Compilers generally allow to view or output the preprocessed code, which
|
|
||||||
can be used for debugging or to copy-paste the generated code.</li>
|
|
||||||
</ul>
|
|
||||||
<p>Most unfortunately, the preprocessor is a very low level preprocessor that
|
|
||||||
specifically does not support repetition or recursive macros. Library support
|
|
||||||
is needed!</p>
|
|
||||||
<p><i>For detailed information on the capabilities and limitations of the preprocessor,
|
|
||||||
please refer to the C++ standard <A href="bibliography.htm#[Std]">[Std]</A>.</i></p>
|
|
||||||
<h3>The motivation example revisited</h3>
|
|
||||||
<p>Using the primitives of the PREPROCESSOR library, the is_function_tester()s
|
|
||||||
could be implemented like this:</p>
|
|
||||||
|
|
||||||
<pre>#define IS_FUNCTION_TESTER(N,_)\
|
|
||||||
template<class R BOOST_PP_COMMA_IF(N) BOOST_PP_ENUM_PARAMS(N, class A)>\
|
|
||||||
yes_type is_function_tester(R (*)(BOOST_PP_ENUM_PARAMS(N,A)));

<P><B>NOTES:</B> You can extend this example by defining more and different kinds

introduced in <A href="bibliography.htm#[Barton]">[Barton]</A> or a Layered Architecture (see for instance

<A href="bibliography.htm#[Czarnecki]">[Czarnecki]</A>). However, at some point you must type the operator tokens
