black-hat - finds and displays a black-hole path
is a one-shot tool for displaying a simple trace of a
program containing a black-hole error. The trace shows the
pattern of function reductions from the first variable in the
black hole, to the next appearance of that variable.
Note that the traced program must first be compiled using the
Hat tracing tools, and executed to generate a trace file.
Possible options are as follows:
control whether to show functions qualified by the name
of their module
subexpressions in printed expressions are cut off and
replaced with a placeholder below a depth of DEPTH
control whether to show the root of the search path, or
just the path from the black-hole variable
control whether to show source references for each
expression on the path
control whether to show the number of accesses to the
control whether to show the octal addresses of the
expression nodes, along side the pretty-printed versions
