When querying for executions of specific functions or source lines, Pernosco supports condition expressions and print expressions. Executions where the condition is false are ignored. Print expressions are evaluated and their results shown alongside each function or line execution.
Conditional expressions function much like conditional breakpoints. Print expressions enable on-the-fly "logging"-style debugging — without having to rebuild or even reexecute the program. Thus, even if you're more used to "printf debugging" than using an interactive debugger, Pernosco can give you the best printf debugging experience you've ever had!
