A CLI tool for QUICKLY preparing simple network diagrams

Language

• The script takes an argument string declaring topology and layout. This means 1) the links between nodes and 2) the desired location of nodes in your diagram.

Links between nodes

• Node names are Letter+Numbers. R for router, S for switch, H for host. Labels are auto-generated.
• Links are declared with a dash. R1-S1 means router 1 is connected to switch 1.
• Links from a node to several hosts can be shortened by ellipsis like S1-H1..H4.
• Topology is a sequence of links separated by semicolon.

Location of nodes

• Last component in argument is the diagram layout.
  • Nodes A above B are written A/B.
  • Nodes A and B, side to side, are written A,B.
  • Nodes A to D located side to side are written A,B,C,D or A..D.
  • Nodes A to D located on a stack are written A/B/C/D or A//D.
