Subject:

Bug escaping / unescaping strings

In converting a GDL file to DOT format, I've noticed the following misbehavior taking place. Consider the following node: node: { title: "32" label: "string \"spring \\\"sling\\\" sting\" swing" } Graph::Easy seems to be unescaping characters in the label, then selectively re-escaping them (e.g., only escaping the quotes): 1. string \"spring \\\"sling\\\" sting\" swing 2. string "spring \"sling\" sting" swing 3. string \"spring \\"sling\\" sting\" swing By not properly escaping the backslash, the sequence \\" indicates the end of the label string, which generates a parse error in dot.

Thanx for your report, you are right, I forgot to re-escape the backslash. Now added that to As_graphviz.pm, the fix will appear in v0.65 of Graph::Easy.
