//
// Global.pp
//
// This file is read in before any of the individual Sources.pp files
// are read.  It defines a few global variables that are useful to all
// different kinds of build_types.
//

// We start off by defining a number of map variables.  These are
// special variables that can be used to look up a particular named
// scope according to a key (that is, according to the value of some
// variable defined within the scope).

// A named scope is defined using the #begin name .. #end name
// sequence.  In general, we use these sequences in the various
// Sources.pp files to define the various targets to build.  Each
// named scope carries around its set of variable declarations.  The
// named scopes are associated with the dirname of the directory in
// which the Sources.pp file was found.


// The first map variable lets us look up a particular library target
// by its target name.  The syntax here indicates that we are
// declaring a map variable called "all_libs" whose key is the
// variable $[TARGET] as defined in each instance of a named scope
// called "static_lib_target," "lib_target," and so on in every
// Sources.pp file.  (The */ refers to all the Sources.pp files.  We
// could also identify a particular file by its directory name, or
// omit the slash to refer to our own Sources.pp file.)

// After defining this map variable, we can look up other variables
// that are defined for the corresponding target.  For instances,
// $[all_libs $[SOURCES],dconfig] will return the value of the SOURCES
// variable as set for the dconfig library (that is, the expression
// $[SOURCES] is evaluated within the named scope whose key is
// "dconfig"--whose variable $[TARGET] was defined to be "dconfig").
#map all_libs TARGET(*/static_lib_target */ss_lib_target */lib_target */noinst_lib_target */test_lib_target */metalib_target)

// This map variable allows us to look up global variables that might
// be defined in a particular Sources.pp, e.g. in the "toplevel" file.
#map dir_type DIR_TYPE(*/)

// These allow us to determine whether a particular local library is a
// static or a dynamic library.  If the library name appears in the
// static_libs map, it is a static library (i.e. libname.a);
// otherwise, it is a dynamic library (libname.so).  The target
// ss_lib_target is a special case: these libraries are dynamic where
// it's easy to make them so (e.g. on Unix platforms), and static on
// platforms where dynamic libraries aren't quite so robust (e.g. on
// Windows).

// This lets us identify which metalib, if any, is including each

#map module COMPONENT_LIBS(*/metalib_target)

// This lets up look up components of a particular metalib.
