pydevDAG._print._print module

pydevDAG._print._print

Textual display of graph.

class pydevDAG._print._print.LineArrangements

Bases: object

Sort out nodes and their relationship to each other in printing.

classmethod node_strings(config, graph, orphan, last, diffstatus, indent, node)

Generates print information about nodes reachable from node including itself.

Parameters:

• LineArrangementsConfig – config
• graph (DiGraph) – the graph
• orphan (bool) – True if this node has no parents, otherwise False
• last (bool) – True if this node is the last child, otherwise False
• diffstatus (DiffStatus) – the diffstatus of the edge
• indent (int) – the indentation level
• node (Node) – the node to print

Returns:

a table of information to be used for further display

Return type:

dict of str * object

Fields in table: * diffstatus - the diffstatus of the edge to this node * indent - the level of indentation * last - whether this node is the last child of its parent * node - the table of information about the node itself * orphan - whether this node has no parents

classmethod node_strings_from_graph(config, graph)

Generates print information about nodes in graph. Starts from the roots of the graph.

Parameters:

• LineArrangementsConfig – config
• graph (DiGraph) – the graph

Returns:

a table of information to be used for further display

Return type:

list of dict of str * object

Fields in table: * diffstatus - the diffstatus of the edge to this node * indent - the level of indentation * last - whether this node is the last child of its parent * node - the table of information about the node itself * orphan - whether this node has no parents

classmethod node_strings_from_root(config, graph, node)

Generates print information about nodes reachable from node including itself. Assumes that the node is a root and supplies some appropriate defaults.

Parameters:

• LineArrangementsConfig – config
• graph (DiGraph) – the graph
• node (Node) – the node to print

Returns:

a table of information to be used for further display

Return type:

dict of str * object

Fields in table: * diffstatus - the diffstatus of the edge to this node * indent - the level of indentation * last - whether this node is the last child of its parent * node - the table of information about the node itself * orphan - whether this node has no parents

class pydevDAG._print._print.LineArrangementsConfig(info_func, conversion_func, sort_key)

Bases: object

Class that represents the configuration for LineArrangements methods.

class pydevDAG._print._print.LineInfo(graph, keys, alignment, getters)

Bases: object

Class that generates info for a single line.

info(node, keys=None, conv=<function <lambda> at 0x7fa3c18ea050>)

Function to generate information to be printed for node.

Parameters:

• node (Node) – the node
• keys (list of str or NoneType) – list of keys for values or None
• conv ((str * object) -> str) – a conversion function that converts values to str

Returns:

a mapping of keys to values

Return type:

dict of str * (str or NoneType)

Only values for elements at x in keys are calculated. If keys is None, return an item for every index. If keys is the empty list, return an empty dict. Return None for key in keys that can not be satisfied.

If strings is set, convert all values to their string representation.

class pydevDAG._print._print.Print

Bases: object
