Automake::Variable - support for variable definitions

=head1 SYNOPSIS

use Automake::Variable;
  use Automake::VarDef;

# Defining a variable.
  Automake::Variable::define($varname, $owner, $type,
                             $cond, $value, $comment,
                             $where, $pretty)

# Looking up a variable.
  my $var = var $varname;
  if ($var)
    {
      ...
    }

# Looking up a variable that is assumed to exist.
  my $var = rvar $varname;

# The list of conditions where $var has been defined.
  # ($var->conditions is an Automake::DisjConditions,
  # $var->conditions->conds is a list of Automake::Condition.)
  my @conds = $var->conditions->conds

# Access to the definition in Condition $cond.
  # $def is an Automake::VarDef.
  my $def = $var->def ($cond);
  if ($def)
    {
      ...
    }

# When the conditional definition is assumed to exist, use
  my $def = $var->rdef ($cond);

=head1 DESCRIPTION

This package provides support for Makefile variable definitions.

An C<Automake::Variable> is a variable name associated to possibly
many conditional definitions.  These definitions are instances
of C<Automake::VarDef>.

Therefore obtaining the value of a variable under a given
condition involves two lookups.  One to look up the variable,
and one to look up the conditional definition:

my $var = var $name;
  if ($var)
    {
      my $def = $var->def ($cond);
      if ($def)
        {
          return $def->value;
        }
      ...
    }
  ...

When it is known that the variable and the definition
being looked up exist, the above can be simplified to

return var ($name)->def ($cond)->value; # Do not write this.

but is better written

return rvar ($name)->rdef ($cond)->value;

or even

return rvardef ($name, $cond)->value;

The I<r> variants of the C<var>, C<def>, and C<vardef> methods add an
extra test to ensure that the lookup succeeded, and will diagnose
failures as internal errors (with a message which is much more
informative than Perl's warning about calling a method on a
non-object).

Get the value of C<$var> as a list, given a specified condition,
without recursing through any subvariables.

C<$cond> is the condition of interest.  C<$var> does not need
to be defined for condition C<$cond> exactly, but it needs
to be defined for at most one condition implied by C<$cond>.

C<$parent> and C<$parent_cond> designate the name and the condition
of the parent variable, i.e., the variable in which C<$var> is
being expanded.  These are used in diagnostics.

For example, if C<A> is defined as "C<foo $(B) bar>" in condition
C<TRUE>, calling C<rvar ('A')->value_as_list (TRUE)> will return
C<("foo", "$(B)", "bar")>.

Return the contents of C<$var> as a list, split on whitespace.  This
will recursively follow C<$(...)> and C<${...}> inclusions.  It
preserves C<@...@> substitutions.

C<%options> is a list of option for C<Variable::traverse_recursively>
(see this method).  The most useful is C<cond_filter>:

$var->value_as_list_recursive (cond_filter => $cond)

will return the contents of C<$var> and any subvariable in all
conditions implied by C<$cond>.

C<%options> can also carry options specific to C<value_as_list_recursive>.
Presently, the only such option is C<location =E<gt> 1> which instructs
C<value_as_list_recursive> to return a list of C<[$location, @values]> pairs.

Define or append to a new variable.

C<$owner>: owner of the variable (one of C<VAR_MAKEFILE>,
C<VAR_CONFIGURE>, or C<VAR_AUTOMAKE>, defined by L<Automake::VarDef>).
Variables can be overridden, provided the new owner is not weaker
(C<VAR_AUTOMAKE> < C<VAR_CONFIGURE> < C<VAR_MAKEFILE>).

C<$type>: the type of the assignment (C<''> for C<FOO = bar>,
C<':'> for C<FOO := bar>, and C<'+'> for C<'FOO += bar'>).

C<$cond>: the C<Condition> in which C<$var> is being defined.

C<$value>: the value assigned to C<$var> in condition C<$cond>.

C<$comment>: any comment (C<'# bla.'>) associated with the assignment.
Comments from C<+=> assignments stack with comments from the last C<=>
assignment.

C<$where>: the C<Location> of the assignment.

C<$pretty>: whether C<$value> should be pretty printed (one of
C<VAR_ASIS>, C<VAR_PRETTY>, C<VAR_SILENT>, or C<VAR_SORTED>, defined
by by L<Automake::VarDef>).  C<$pretty> applies only to real
assignments.  I.e., it does not apply to a C<+=> assignment (except
when part of it is being done as a conditional C<=> assignment).

This function will all run any hook registered with the C<hook>
function.

Split the value of the Automake::Variable C<$var> on space, and
traverse its components recursively.

If C<$cond_filter> is an C<Automake::Condition>, process any
conditions which are true when C<$cond_filter> is true.  Otherwise,
process all conditions.

We distinguish two kinds of items in the content of C<$var>.
Terms that look like C<$(foo)> or C<${foo}> are subvariables
and cause recursion.  Other terms are assumed to be filenames.

Each time a filename is encountered, C<&fun_item> is called with the
following arguments:

($var,        -- the Automake::Variable we are currently
                   traversing
   $val,        -- the item (i.e., filename) to process
   $cond,       -- the Condition for the $var definition we are
                   examining (ignoring the recursion context)
   $full_cond)  -- the full Condition, taking into account
                   conditions inherited from parent variables
                   during recursion

If C<inner_expand> is set, variable references occurring in filename
(as in C<$(BASE).ext>) are expanded before the filename is passed to
C<&fun_item>.

If C<skip_ac_subst> is set, Autoconf @substitutions@ will be skipped,
i.e., C<&fun_item> will never be called for them.

C<&fun_item> may return a list of items, they will be passed to
C<&fun_store> later on.  Define C<&fun_item> or @<&fun_store> as
C<undef> when they serve no purpose.

Once all items of a variable have been processed, the result (of the
calls to C<&fun_items>, or of recursive traversals of subvariables)
are passed to C<&fun_collect>.  C<&fun_collect> receives three
arguments:

($var,         -- the variable being traversed
   $parent_cond, -- the Condition inherited from parent
                    variables during recursion
   @condlist)    -- a list of [$cond, @results] pairs
                    where each $cond appear only once, and @result
                    are all the results for this condition.

Typically you should do C<$cond->merge ($parent_cond)> to recompute
the C<$full_cond> associated to C<@result>.  C<&fun_collect> may
return a list of items, that will be used as the result of
C<Automake::Variable::traverse_recursively> (the top-level, or its
recursive calls).

#
# | if FOO1
# | A1=1
# | endif
# |
# | if FOO2
# | A2=2

# |
# | B=$(A1) $(A2) ... $(AN)
# |
# | c_SOURCES=$(B)
# | d_SOURCES=$(B)
#
# The generated c_OBJECTS and d_OBJECTS will share the same variable
# definitions.
#
# This setup can be the case of a testsuite containing lots (>100) of
# small C programs, all testing the same set of source files.

=item C<$resvar = $var-E<gt>transform_variable_recursively ($resvar, $base, $nodefine, $where, &fun_item, [%options])>

Traverse C<$var> recursively, and create a C<$resvar> variable in
which each filename in C<$var> have been transformed using
C<&fun_item>.  (C<$var> may be a variable name in the first syntax.
It must be an C<Automake::Variable> otherwise.)

Helper variables (corresponding to sub-variables of C<$var>) are
created as needed, using C<$base> as prefix.

Arguments are:
  $var       source variable to traverse
  $resvar    resulting variable to define
  $base      prefix to use when naming subvariables of $resvar
  $nodefine  if true, traverse $var but do not define any variable
             (this assumes &fun_item has some useful side-effect)
  $where     context into which variable definitions are done
  &fun_item  a transformation function -- see the documentation
             of &fun_item in Automake::Variable::traverse_recursively.

This returns the string C<"\$($RESVAR)">.

C<%options> is a list of options to pass to
C<Variable::traverse_recursively> (see this method).
