This constitues a workaround for an issue, reported and investigated by Krzysztof Stryjek. Added erroneously omitted "if DEBUG" condition to trace print statements, and preset DEBUG to False (instead of True). Unicode character supported by default.

(The graph name is the name that follows the graph or digraph keyword at the beginning of the graph script.) Thus, in order to prevent from image file name clashes, graphs on a page should have unique names. When a graph image is rendered, the image file name is mangled with the graph name. You'll see a completetion message like this: Then press the button to delete the attachments. Of course, it is possible, though unlikely, that there are "foreign" attachments that do match the naming pattern, so take a closer look at the file names presented, and uncheck those you don't want deleted. When the action is invoked, it wil detect attachments that match the GraphViz parser's specific naming pattern, and prompt you for deletion: The action is based on the upcoming Attachment Deletions Actions package, a prelimiary version of which is (partially) included herein. Graph image cleanup is supported with the GraphVizCleanup action. It is possible to delete these images one by one, vie moin's attachments action, but this is too cumbersome - over time, there may be just too many such files. This potentially leads to a bunch of obsolete graph images in your attachment directory. (It will be reused in case the graph script is reverted to the previous state.) When a graph is changed, another image is created, and the old image is not deleted. When a graph is rendered, an image file is created in the page's attachment area. # node/edge formatting defaults 3 ATTEMPT_TO_JOIN_EDGES = ' concentrate=true ' # easier to remember 4 LEFT_TO_RIGHT = ' rankdir=LR ' # easier to remember Currently, there are the snippets:ġ class Snippets: 2 STD_GRAPH_HEADER =. The available snippet set is represented by attributes of the class Snippets (in module plugin/parser/MoinGraphViz/main.py). They are included in the graph using the notation $Snippet.įor example, the graph image at the top of this page has been generated by: Snippets contain commonly used pieces of graph description code. In order to support this need, the extension features a graph snippet concept.
#Graphviz circo code
Clearly, including that code is better then retyping it. Getting the default formatting look "right" is a cumbersome repetitive task of writing the same chunk of graph code in every graph you design. The default GraphViz formatting is not particularly appealing.
If no layouter is specified, the configured DEFAULT_TOOL is invoked. Where layouter is optional and one of dot, neato, twopi, fdp, circo (generally all layouters in the GraphViz toolset are supported). Graph scripts are written in the DOT language. Graphs are specified by graph scripts in the parser section. The presets assume that your GraphViz tools are in the subdirectory tools of your moin server working directory. GRAPHVIZ_TOOLS_DIR = ' tools ' # Where are your GraphViz executables? DEFAULT_TOOL = ' DOT ' # What is your default tool if not specified in the parser?
