""" """ To add this tool to your project: def options(conf): opt.load('msvs') It can be a good idea to add the sync_exec tool too. To generate solution files: $ waf configure msvs To customize the outputs, provide subclasses in your wscript files: from waflib.extras import msvs class vsnode_target(msvs.vsnode_target): def get_build_command(self, props): # likely to be required return "waf.bat build" def collect_source(self): # likely to be required ... class msvs_bar(msvs.msvs_generator): def init(self): msvs.msvs_generator.init(self) self.vsnode_target = vsnode_target The msvs class re-uses the same build() function for reading the targets (task generators), you may therefore specify msvs settings on the context object: def build(bld): bld.solution_name = 'foo.sln' bld.waf_command = 'waf.bat' bld.projects_dir = bld.srcnode.make_node('.depproj') bld.projects_dir.mkdir() For visual studio 2008, the command is called 'msvs2008', and the classes such as vsnode_target are wrapped by a decorator class 'wrap_2008' to provide special functionality.
