setuptools._distutils.core.Distribution

Construct a new Distribution instance: initialize all the attributes of a Distribution, and then use 'attrs' (a dictionary mapping attribute names to values) to assign some of those attributes their "real" values. (Any attributes not mentioned in 'attrs' will be assigned to some null value: 0, None, an empty list or dictionary, etc.) Most importantly, initialize the 'command_obj' attribute to the empty dictionary; this will be filled in with real command objects by 'parse_command_line()'.

Set final values for all the options on the Distribution instance, analogous to the .finalize_options() method of Command objects.

Find as many configuration files as should be processed for this platform, and return a list of filenames in the order in which they should be parsed. The filenames returned are guaranteed to exist (modulo nasty race conditions). There are multiple possible config files: - distutils.cfg in the Distutils installation directory (i.e. where the top-level Distutils __inst__.py file lives) - a file in the user's home directory named .pydistutils.cfg on Unix and pydistutils.cfg on Windows/Mac; may be disabled with the ``--no-user-cfg`` option - setup.cfg in the current directory - a file named by an environment variable

Return the class that implements the Distutils command named by 'command'. First we check the 'cmdclass' dictionary; if the command is mentioned there, we fetch the class object from the dictionary and return it. Otherwise we load the command module ("distutils.command." + command) and fetch the command class from the module. The loaded class is also stored in 'cmdclass' to speed future calls to 'get_command_class()'. Raises DistutilsModuleError if the expected module could not be found, or if that module does not define the expected class.

Get a list of (command, description) tuples. The list is divided into "standard commands" (listed in distutils.command.__all__) and "extra commands" (mentioned in self.cmdclass, but not a standard command). The descriptions come from the command class attribute 'description'.

Return the command object for 'command'. Normally this object is cached on a previous call to 'get_command_obj()'; if no command object for 'command' is in the cache, then we either create and return it (if 'create' is true) or return None.

Return a list of packages from which commands are loaded.

Get the option dictionary for a given command. If that command's option dictionary hasn't been created yet, then create it and return the new dictionary; otherwise, return the existing option dictionary.

If there were any non-global "display-only" options (--help-commands or the metadata display options) on the command line, display the requested info and return true; else return false.

Parse the setup script's command line, taken from the 'script_args' instance attribute (which defaults to 'sys.argv[1:]' -- see 'setup()' in core.py). This list is first processed for "global options" -- options that set attributes of the Distribution instance. Then, it is alternately scanned for Distutils commands and options for that command. Each new command terminates the options for the previous command. The allowed options for a command are determined by the 'user_options' attribute of the command class -- thus, we have to be able to load command classes in order to parse the command line. Any error in that 'options' attribute raises DistutilsGetoptError; any error on the command-line raises DistutilsArgError. If no Distutils commands were found on the command line, raises DistutilsArgError. Return true if command-line was successfully parsed and we should carry on with executing commands; false if no errors but we shouldn't execute commands (currently, this only happens if user asks for help).

Print a subset of the list of all commands -- used by 'print_commands()'.

Print out a help message listing all available commands with a description of each. The list is divided into "standard commands" (listed in distutils.command.__all__) and "extra commands" (mentioned in self.cmdclass, but not a standard command). The descriptions come from the command class attribute 'description'.

Reinitializes a command to the state it was in when first returned by 'get_command_obj()': ie., initialized but not yet finalized. This provides the opportunity to sneak option values in programmatically, overriding or supplementing user-supplied values from the config files and command line. You'll have to re-finalize the command object (by calling 'finalize_options()' or 'ensure_finalized()') before using it for real. 'command' should be a command name (string) or command object. If 'reinit_subcommands' is true, also reinitializes the command's sub-commands, as declared by the 'sub_commands' class attribute (if it has one). See the "install" command for an example. Only reinitializes the sub-commands that actually matter, ie. those whose test predicates return true. Returns the reinitialized command object.

Do whatever it takes to run a command (including nothing at all, if the command has already been run). Specifically: if we have already created and run the command named by 'command', return silently without doing anything. If the command named by 'command' doesn't even have a command object yet, create one. Then invoke 'run()' on that command object (or an existing one).

Run each command that was seen on the setup script command line. Uses the list of commands found and cache of command objects created by 'get_command_obj()'.
