CallGraph::Dumper - Dump a call graph into a string representation
my $dumper = CallGraph::Dumper->new(root => $root, indent => 8, dups => 0); print $dumper->dump;
This module dumps a call graph into a string representation. The output looks something like this:
MAIN EXTSUB * 1 SUB1 SUB11 SUB12 SUB2 SUB1 (1) SUB21
This means that MAIN calls EXTSUB, which is labeled with an asterisk because it is external (meaning it is not defined within the program that was parsed), SUB1, and SUB2. SUB1 calls SUB11 and SUB12. SUB2 calls SUB1; to avoid duplication, a link is made by labeling SUB1 with a 1. This is the default behavior, with 'dups' => 0. When dups => 1, the branch is duplicated:
MAIN EXTSUB * SUB1 SUB11 SUB12 SUB2 SUB1 SUB11 SUB12 SUB21
In case of recursion, the label system is used even with dups => 1, to avoid an endless loop.
Creates a new dumper. The root option must be given and it must be a CallGraph::Node object. The other options are the following:
The number of spaces to indent each call level. The default is 8.
If true, duplicate a branch that has already been called. If false, place a level pointing to the first place where the branch was defined. The default is false.
Turn the call graph into a string representation.
