Warning

THIS MODULE DOES NOT HAVE STABLE PUBLIC API

class plainbox.impl.commands.dev.DevCommand(provider_loader, config_loader)[source]

Bases: plainbox.impl.commands.PlainBoxCommand

Command hub for various development commands.

add_subcommand(subparsers)

Add a parser to the specified subparsers instance.

Returns:The new parser for the added subcommand

This command works by convention, depending on get_command_name(), :meth:`get_command_help(), get_command_description() and get_command_epilog().

autopager()

Enable automatic pager.

This invokes autopager() which wraps execution in a pager program so that long output is not a problem to read. Do not call this in interactive commands.

get_command_description()

Get a multi-line description string associated with this command, as seen on command line.

The description is printed after command usage but before argument and option definitions.

Returns:self.description, if defined
Returns:A substring of the class docstring between the first line (which goes to get_command_help()) and the string @EPILOG@, if present, or the end of the docstring, if any.
Returns:None, otherwise
get_command_epilog()

Get a multi-line description string associated with this command, as seen on command line.

The epilog is printed after the definitions of arguments and options

Returns:self.epilog, if defined
Returns:A substring of the class docstring between the string @EPILOG and the end of the docstring, if defined
Returns:None, otherwise
get_command_help()

Get a single-line help string associated with this command, as seen on command line.

Returns:self.help, if defined
Returns:The first line of the docstring of this class, if any
Returns:None, otherwise
get_command_name()

Get the name of the command, as seen on command line.

Returns:self.name, if defined
Returns:lower-cased class name, with the string “command” stripped out
get_gettext_domain()

Get the gettext translation domain associated with this command.

The domain will be used to translate the description, epilog and help string, as obtained by their respective methods.

Returns:self.gettext_domain, if defined
Returns:None, otherwise. Note that it will cause the string to be translated with the globally configured domain.
get_localized_docstring()

Get a cleaned-up, localized copy of docstring of this class.

gettext_domain = 'plainbox'

register_arguments(parser)

Implement to customize which arguments need to be added to a parser.

This method differs from register_parser() in that it allows commands which implement it to be invoked directly from a tool class (without being a subcommand that needs to be selected). If implemented it should be used from within register_parser() to ensure identical behavior in both cases (subcommand and tool-level command)
