Overview¶

This file contains 9 documented elements.

Functions¶

usage()¶

Prints the version information, usage message, and a help hint for the dottoxml command-line tool to standard output. The output includes the application name and version (dottoxml 1.6, 2014-04-10, Dirk Baechle), the usage string defined in usgmsg, and a prompt directing the user to invoke -h or --help for additional information. This function takes no parameters and returns no value.

exportDot(o, nodes, edges, options)¶

No description available. Writes a DOT-format graph representation to the output stream o by opening a graph [ block and iterating over all provided nodes and edges. For each node in the nodes mapping, it delegates serialization to the node's own exportDot method, passing o and options. Each edge in the edges collection is similarly serialized via its exportDot method, with o, nodes, and options forwarded as arguments.

Parameters: - o - nodes - edges - options

exportGML(o, nodes, edges, options)¶

No description available. Writes a GML (Graph Modelling Language) representation of a directed, hierarchic graph to the output stream o. The function writes the opening graph [ block with fixed metadata comments, then iterates over all nodes and edges, delegating serialization to each element's own exportGML method, before closing the block with ]. The options parameter is passed through to each node's and edge's individual export call.

Parameters: - o - nodes - edges - options

intes()¶

No description available. Displays a localized input dialog prompting the user to enter a stratigraphic site identifier. The dialog title and message are retrieved from language-specific lookup dictionaries (_INTES_TITLE and _INTES_MSG) based on the current language returned by _get_lang(), falling back to English if the language key is not found. Returns the user-entered value as a string, or prints the error message if a KeyError is raised.

reverse()¶

return true or false about the order epoch

exportGraphml(o, nodes, edges, options, ff)¶

Exports a graph structure to a GraphML file compatible with the yEd graph editor, constructing a complete XML document with the required namespace declarations, key definitions, and a table node (y:TableNode) that organizes stratigraphic units into chronological rows derived from the provided nodes and edges collections. The function iterates over sorted epoch and unit-prefix entries to generate labeled rows and columns, delegates individual node and edge rendering to their respective exportGraphml methods, and embeds three inline SVG resources representing graphical symbols. The fully serialized XML document is written as a UTF-8 encoded string to the output object o.

Parameters: - o - nodes - edges - options - ff

exportGDF(o, nodes, edges, options)¶

No description available. Writes a GDF (Graph Data Format) representation of a graph to the output stream o. It begins by writing the node definition header "nodedef> name", then iterates over all entries in the nodes mapping and all items in the edges collection, delegating serialization to each element's own exportGDF method. The function concludes by writing the edge definition header "edgedef> node1,node2" to the output stream.

Parameters: - o - nodes - edges - options

main()¶

Parses command-line arguments to configure output format (Graphml, GML, GDF, or DOT), encoding, and display options, then reads a DOT-format input file to collect node and edge definitions. It resolves default attributes, optionally removes unreferenced nodes via a sweep operation, and writes the converted graph data to the specified output file using the selected export format.
