This allows including extension headers in code without using -the bundle name. Including extension headers in this way is much better, -since there is no dependency on the (meaningless and non-persistent) bundle -name in the code using the header. - -For example, after running lv2config (and setting the compiler include -path appropriately), LV2 headers could be included like so: - -#include "lv2/lv2plug.in/ns/lv2core/lv2.h" -#include "lv2/lv2plug.in/ns/ext/event/event.h" -#include "lv2/example.org/foo/foo.h" - -Where the initial "lv2" is arbitrary; in this case lv2config's output -directory was "lv2", and that directory's parent was added to the compiler -include search path. It is a good idea to use such a prefix directory so -domain names do not conflict with anything else in the include path. -""" - -from __future__ import print_function - -__authors__ = 'David Robillard' -__license = 'GNU GPL v3 or later <http://www.gnu.org/licenses/gpl.html>' -__contact__ = 'devel@lists.lv2plug.in' -__date__ = '2010-10-05' - -import errno -import glob -import os -import stat -import sys - -redland = True - -try: - import RDF # Attempt to import Redland -except: - try: - import rdflib # Attempt to import RDFLib - redland = False - except: - print("""Failed to import `RDF' (Redland) or `rdflib'. -(Please install either package, likely `python-librdf' or `python-rdflib')""",file=sys.stderr) - sys.exit(1) - -def rdf_namespace(uri): - "Create a new RDF namespace" - if redland: - return RDF.NS(uri) - else: - return rdflib.Namespace(uri) - -def rdf_load(uri): - "Load an RDF model" - if redland: - model = RDF.Model() - parser = RDF.Parser(name="turtle") - parser.parse_into_model(model, uri) - else: - model = rdflib.ConjunctiveGraph() - model.parse(uri, format="n3") - return model - -def rdf_find_type(model, rdf_type): - "Return a list of the URIs of all resources in model with a given type" - if redland: - results = model.find_statements(RDF.Statement(None, rdf.type, rdf_type)) - ret = [] - for r in results: - ret.append(str(r.subject.uri)) - return ret - else: - results = model.triples([None, rdf.type, rdf_type]) - ret = [] - for r in results: - ret.append(r[0]) - return ret - -rdf = rdf_namespace('http://www.w3.org/1999/02/22-rdf-syntax-ns#') -lv2 = rdf_namespace('http://lv2plug.in/ns/lv2core#') - -def lv2_path(): - "Return the LV2 search path (LV2_PATH in the environment, or a default)." - if 'LV2_PATH' in os.environ: - return os.environ['LV2_PATH'] - else: - ret = '/usr/lib/lv2' + os.pathsep + '/usr/local/lib/lv2' - print('LV2_PATH unset, using default', ret) - return ret - -def __mkdir_p(path): - "Equivalent of UNIX mkdir -p" - try: - os.makedirs(path) - except OSError, e: - if e.errno == errno.EEXIST: - pass - else: - raise - -def build_tree(search_path, outdir): - """Build a directory tree under outdir containing symlinks to all LV2 - extensions found in search_path, such that the symlink paths correspond to - the extension URIs.""" - if os.path.basename(outdir) != 'lv2': - print >> sys.stderr, "lv2config: output dir must be named `lv2'" - sys.exit(1) - - if os.access(outdir, os.F_OK) and not os.access(outdir, os.W_OK): - print ("lv2config: cannot build `%s': Permission denied" % outdir, file=sys.stderr) - sys.exit(1) - - for dir in search_path.split(os.pathsep): - if not os.access(dir, os.F_OK): - continue - - print('Building includes in %s for %s/*.lv2' % (outdir, dir)) - for bundle in glob.glob(os.path.join(dir, '*.lv2')): - # Load manifest into model - manifest = rdf_load('file://' + os.path.join(bundle, 'manifest.ttl')) - - # Query extension URI - specs = rdf_find_type(manifest, lv2.Specification) - for ext_uri in specs: - ext_path = os.path.normpath(ext_uri[ext_uri.find(':') + 1:].lstrip('/')) - ext_dir = os.path.join(outdir, ext_path) - - # Make parent directories - __mkdir_p(os.path.dirname(ext_dir)) - - # Remove existing symlink if necessary - if os.access(ext_dir, os.F_OK): - mode = os.lstat(ext_dir)[stat.ST_MODE] - if stat.S_ISLNK(mode): - os.remove(ext_dir) - else: - raise Exception(ext_dir + " exists and is not a link") - - # Make symlink to bundle directory - os.symlink(bundle, ext_dir) - -def __usage(): - script = os.path.basename(sys.argv[0]) - print("""Usage: %(script)s - Build the default system lv2 include directories, - /usr/include/lv2 and /usr/local/include/lv2 - -Usage: %(script)s INCLUDEDIR - Build an lv2 include directory tree at INCLUDEDIR - for all extensions found in $LV2_PATH. - -Usage: %(script)s BUNDLESDIR INCLUDEDIR - Build an lv2 include directory tree at INCLUDEDIR - for all extensions found in bundles under BUNDLESDIR. -""" % {'script' : script}) - -if __name__ == "__main__": - args = sys.argv[1:] - - if len(args) == 0: - build_tree('/usr/local/lib/lv2', '/usr/local/include/lv2') - build_tree('/usr/lib/lv2', '/usr/include/lv2') - build_tree('/Library/Audio/Plug-Ins/LV2', '/Developer/Headers/lv2') - - elif '--help' in args or '-h' in args: - __usage() - - elif len(args) == 1: - build_tree(lv2_path(), args[0]) - - elif len(args) == 2: - build_tree(args[0], args[1]) - - else: - __usage() - sys.exit(1) |
