dijkstra - source distance filter for Graphviz
dijkstra [ -adp? ] [ sourcenode file ]
DIJKSTRA(1) General Commands Manual DIJKSTRA(1) NAME dijkstra - single-source distance filter for Graphviz SYNOPSIS dijkstra [ -adp? ] [ sourcenode file ] DESCRIPTION dijkstra reads a stream of Graphviz formatted graphs and for each com- putes the distance of every node from sourcenode. Edge length is given in the len attribute, and the default is 1. The dist attribute of every node is set to its distance from sourcenode. If the -p flag is used, the prev attribute of each node reachable from sourcenode is set to the name of the previous node on a shortest path. The graph attribute maxdist is set to the maximum dist of all nodes in the graph. If the -d flag is used, the graph is treated as directed and only for- ward edges are used. By default, if the graph is disconnected, the dist attribute of nodes unreachable from sourcenode are left untouched, and maxdist is set to the maximum of any previous value and the largest distance recorded in this run. On the other hand, if the -a flag is used, the dist attribute of an unreachable node is assigned a very large value, and maxdist records the maximum distance found in the component containing sourcenode. Any number of sourcenode file pairs may be given. If the last file is missing, stdin is used. All output is written to stdout. In a typical application, dist and maxdist can drive a downstream cal- culation of color or some other attribute.
