=head1 DESCRIPTION
This is the documentation for Parrot's embedding API.
=head2 Data structures
=over 4
=item C<Parrot_Interp>
The topmost data structure in Parrot is C<Parrot_Interp>, which represents
a Parrot interpreter. It is a required argument to almost every Parrot API
function. The structure is opaque in an embedded environment, so you cannot
directly access any of its members.
=item C<Parrot_PackFile>
A Parrot packfile, the internal structure containing Parrot bytecode.
=item C<Parrot_String>
Parrot's internal string type, which contains character encoding information.
=item C<Parrot_PMC>
A Polymorphic Container. This is the opaque external type for (PMC *). Note
that this is a macro, so there can be only one C<Parrot_PMC> declaration per
line.
=item C<Parrot_Int>
=item C<Parrot_Float>
=item C<Parrot_UInt>
Parrot's numeric types.
=back
=head2 Constants
Not documented yet.
=head2 Type signatures
TODO: Write about signature strings
=head2 Interpreter initialization and destruction
=over 4
=item C<Parrot_Interp Parrot_new(Parrot_Interp parent)>
Creates a new interpreter, inheriting some data structures from a parent
interpreter, if supplied. The first interpreter in any process should be
created with a NULL parent, and all subsequent interpreters in the same
process should use the first interpreter as their parent. Failure to do so
may result in unpredictable errors.
=item C<Parrot_set_flag(PARROT_INTERP, Parrot_int flags)>
Sets or unsets interpreter flags. Flags should be OR'd together. Valid
flags include:
=over 4
=item PARROT_NO_FLAGS
=item PARROT_BOUNDS_FLAG
=item PARROT_GC_DEBUG_FLAG
=item PARROT_EXTERN_CODE_FLAG
=item PARROT_DESTROY_FLAG
=item PARROT_IS_THREAD
=item PARROT_THR_COPY_INTERP
=item PARROT_THR_THREAD_POOL
=back
See F<interpreter.h> for the definition of these flags (TODO: document flag
definitions here).
=item C<void Parrot_set_run_core(PARROT_INTERP, Parrot_Run_core_t core)>
Sets the runcore for the interpreter. Must be called before executing any
bytecode. Valid runcores include:
=over 4
=item PARROT_SLOW_CORE
=item PARROT_FUNCTION_CORE
=item PARROT_FAST_CORE
=item PARROT_EXEC_CORE
=item PARROT_GC_DEBUG_CORE
=back
See F<interpreter.h> for the definitive list. If you're not sure which runcore
to use, don't call this function. The default will be fine for most cases.
(TODO: document runcores here).
=item C<Parrot_set_trace(Parrot_Interp, Parrot_UInt flags)>
Sets the interpreter's trace flags. Flags should be OR'd together. Valid
flags are:
=over 4
=item PARROT_NO_TRACE
=item PARROT_TRACE_OPS_FLAG
=item PARROT_TRACE_FIND_METH_FLAG
=item PARROT_TRACE_SUB_CALL_FLAG
=item PARROT_ALL_TRACE_FLAGS
Z<>
=back
=item C<void Parrot_set_executable_name(PARROT_INTERP, Parrot_string name)>
Sets the executable name of the calling process. Note that the name is a
Parrot string, not a C string.
=item C<void Parrot_destroy(PARROT_INTERP)>
Destroys an interpreter. At the time of this writing, this is a no-op.
See <Parrot_really_destroy()>.
=item C<void Parrot_really_destroy(PARROT_INTERP, int exit_code)>
Destroys an interpreter, regardless of the environment. The exit code is
currently unused.
=item C<void Parrot_exit(PARROT_INTERP, int status)>
Destroys the interpreter and exits with an exit code of C<status>. Before
exiting, the function calls all registered exit handlers in LIFO order.
C<Parrot_really_destroy()> is usually called as the last exit handler.
=item C<void Parrot_on_exit(PARROT_INTERP,
void (*handler)(Parrot_Interp, int, void *), void *arg)>
Registers an exit handler to be called from C<Parrot_exit()> in LIFO order.
The handler function should accept as arguments an interpreter, an integer
exit code, and an argument (which can be NULL).
=back
=head2 Loading and running bytecode
=over 4
=item C<Parrot_PackFile Parrot_pbc_read(PARROT_INTERP, const char *path, const int debug)>
Reads Parrot bytecode or PIR from the file referenced by C<path>. Returns
a packfile structure for use by C<Parrot_pbc_load()>. C<debug> should be 0.
=item C<void Parrot_pbc_load(PARROT_INTERP, Parrot_PackFile pf)>
Loads a packfile into the interpreter. After this operation the interpreter
is ready to run the bytecode in the packfile.
=item C<void Parrot_runcode(PARROT_INTERP, int argc, char *argv[])>
Runs the bytecode associated with the interpreter. Use C<argc> and C<argv[]>
to pass arguments to the bytecode.
=item C<Parrot_PackFile PackFile_new_dummy(PARROT_INTERP, char *name)>
Creates a "dummy" packfile in lieu of actually creating one from a bytecode
file on disk.
=item C<void Parrot_load_bytecode(PARROT_INTERP, STRING *path)>
Reads and load Parrot bytecode or PIR from the file referenced by C<path>.
You should create a dummy packfile beforehand; see C<PackFile_new_dummy> for
details. Due to the void return type, the behavior of this function on error
is unclear.
=back
=head2 Data manipulation
=head3 Native types
=over 4
=item C<int Parrot_PMC_typenum(PARROT_INTERP, const char *type)>
Returns the internal type number corresponding to C<type>. Useful for
instantiating various Parrot data types.
=item C<char *Parrot_str_to_cstring(PARROT_INTERP, const STRING *s)>
XXX needs to be a formal Parrot_* API.
Returns the C string representation of a Parrot string.
=item C<STRING *Parrot_str_new(PARROT_INTERP, const char *string, int len)>
XXX needs to be a formal Parrot_* API.
Returns the Parrot string representation of a C string.
=item C<string_from_literal(PARROT_INTERP, const char *string)>
XXX needs to be a formal Parrot_* API.
A macro for simplifying calls to C<Parrot_str_new>.
=back
=head3 PMCs
=over 4
=item C<Parrot_PMC Parrot_PMC_new(PARROT_INTERP, int typenum)>
Creates a new PMC of the type identified by C<typenum>. Use
C<Parrot_PMC_typenum> to obtain the correct type number.
=item C<void Parrot_register_pmc(Parrot_PMC pmc)>
Registers an externally created PMC with the garbage collector. You MUST call
this for any PMCs you create outside of Parrot bytecode, otherwise your PMC
may be garbage collected before you are finished using it.
=item C<void Parrot_unregister_pmc(Parrot_PMC pmc)>
Unregisters an externally created PMC from the garbage collector. You MUST call
this after you are finished using PMCs you create outside of Parrot bytecode,
or risk memory leaks.
=back
=head3 Globals

=head2 Calling subroutines
=over 4
=item C<void Parrot_ext_call(PARROT_INTERP, Parrot_PMC sub, const_char *signature, varargs ...)>
Call a Parrot subroutine using the supplied signature. Variables to be filled
with return values are passed as references in the varargs list, after all
arguments.
=back
=head2 Objects
=head3 Creating and destroying objects
=over 4
=item C<Parrot_PMC Parrot_oo_get_class(PARROT_INTERP, Parrot_PMC namespace)>
Returns the class corresponding to the supplied namespace.
=item C<Parrot_PMC Parrot_PMC_instantiate(PARROT_INTERP, Parrot_PMC the_class, Parrot_PMC arg)>
Instantiates a new object of class C<the_class>, which can be obtained from
C<Parrot_oo_get_class()>. Passes an optional PMC argument C<arg> to the
constructor (see init versus init_pmc). Use C<PMCNULL> if you are not
supplying an argument.
=back
=head3 Calling methods
=over 4
=item C<void Parrot_ext_call(PARROT_INTERP, Parrot_PMC method, const_char *signature, varargs ...)>
Methods are called using the same API function as calling a subroutine. The
first argument should be the object that the method will be invoked on, and it
should have the signature "Pi".

=head1 COMPILING
Note: This section is aimed at you if you are writing an application
external to parrot which links against an installed parrot library.
=head2 Caveats
Several API functions are missing prototypes in Parrot's header files. This
means you may receive type warnings during compilation even though the types
of your arguments and return variables are correct. In this case it is safe
to cast to the correct type; not doing so may cause undesired behavior.
=head2 Compiler and linker flags
Your application will need to include the appropriate header files and
link against parrot and its dependencies.
Because the location of these files can vary from platform to platform, and
build to build, a general method is provided to find out the necessary flags to
use.
pkg-config is a helper tool, now common on many platforms, which many packages
have adopted to provide the necessary compiler and linker flags required to
build against a library. parrot will install a file called F<parrot.pc> which
can be queried using pkg-config.
To start with, find out what version of parrot is installed by running
pkg-config with the C<--modversion> flag. If this command fails with an error,
skip to the end of this section.
pkg-config --modversion parrot
To find out the necessary C<-I> flags, use C<--cflags>:
pkg-config --cflags parrot
... and to find the necessary C<-L> and C<-l> flags, use C<--libs>:
pkg-config --libs parrot
Where both compiling and linking are performed in one step, query both sets of
flags with:
pkg-config --cflags --libs parrot
The pkg-config command can be incorporated with a compile as shown here.
cc src/disassemble.c `pkg-config --cflags --libs parrot`
Most applications will probably choose to run pkg-config as part of a
configure script, so if you are using autoconf you could use a test
such as this.
PARROT_REQUIRED_VERSION=0.4.1
AC_SUBST(PARROT_REQUIRED_VERSION)
PKG_CHECK_MODULES(PARROT, parrot >= $PARROT_REQUIRED_VERSION,
[AC_DEFINE([HAVE_PARROT], 1, [define if have parrot])])
AC_SUBST(PARROT_LIBS)
AC_SUBST(PARROT_CFLAGS)
If parrot has been installed system-wide, then any of the previous
lines should have returned the relevant flags. If it is not installed
in one of the standard places that pkg-config looks, then you will get
an error message.
pkg-config --libs parrot
Package parrot was not found in the pkg-config search path.
Perhaps you should add the directory containing `parrot.pc'
to the PKG_CONFIG_PATH environment variable
No package 'parrot' found
As stated in the error message, use an environment variable to make pkg-config
look in more locations.
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
The last part of the variable will almost certainly be F<.../lib/pkgconfig>.
Set this variable in your login scripts if you need it to be available in
future.
=head1 EXAMPLES
=head2 Load bytecode as a library and run a single subroutine
#include <parrot/parrot.h>
#include <parrot/embed.h>
#include <parrot/extend.h>
int main(int argc, char *argv[])
{
Parrot_Interp interp;
Parrot_PackFile pf;
Parrot_PMC sub;
Parrot_String pstr;
interp = Parrot_new(NULL);
imcc_init(interp);
/* create a new packfile -- any name will do */
pf = PackFile_new_dummy(interp, "my-parrot-code");
pstr = string_from_literal(interp, "foo.pir");
Parrot_load_bytecode(interp, pstr);
/* find the subroutine named "foo" in the global namespace */
pstr = string_from_literal(interp, "foo");
sub = Parrot_ns_find_current_namespace_global(interp, pstr);
/* run foo(), which returns nothing */
Parrot_ext_call(interp, sub, "->");
Parrot_destroy(interp);
return(0);
}
=head1 EXPORTED FUNCTIONS
The Parrot embedding API is not finalized, and it will go through several
deprecation cycles before stabilizing. Below is the comprehensive list of
candidates for inclusion in the Parrot embedding API. It includes the
following types of functions:
=over 4
=item * The core functions documented above
=item * Functions required by macros
=item * Parrot_PMC_* VTABLE wrappers
=item * Miscellaneous functions whose utility outside of the core is
uncertain. This includes functions used by HLLs.
=item * Functions that should be removed in a future deprecation cycle. A
good example of this is most of the internal string_* functions, which now
have formal Parrot_str_* wrappers.
=back
The list may also be augmented if additional functionality is required.
