Valpyk

Valpyk is a Valgrind log parser:

1. Parse plain text Valgrind log
2. Filter errors and memory leaks using Python functions
3. Remove duplicates
4. Display errors and top 10 memory leaks (sorted by size)

See also Valgrind homepage.

Why?

It's hard to read Valgrind raw logs. Valpyk cleanup data and give smart output: skip addresses, process identifier, etc. Example:

Valgrind log:
