This is an unofficial command line client for the yUML web app. Use it to draw class diagrams, activity diagrams and usecase diagrams from the command line, integrate yUML into your documentation workflow or what have you.
yuml (the tool) supports all the styles and formats that yUML (the service)
does, so you can take your pick between scruffy (the default), boring and
plain for the styles and png, pdf or jpg for the format.
Have fun.
Only the -o option is required.
-i Read yuml from FILE instead of stdin
-o Store output in FILE
-f Force format (one of png, pdf, or jpg)
-t Use this diagram type (one of class, activity, or usecase)
-s Use this diagram style (one of scruffy, boring, plain)
--scale Scale output to percentage
-v Print some debug info
echo "[This]-[That]" | ./yuml -s boring -o diagram.png
