code-path-report

CodePathReport is a very powerful tool to visualize the code path of nestest function call. Additionally, it could visulaize time cost and some details of each function call.

Quick start

make copmile
make run

Then you should get the output like this

obstacle_wise_root_executions {
  key: "main"
  value {
    child_executions {
      name: "Root"
      is_code_block_conditional: false
      duration_ms: 0
      child_executions {
        name: "main"
        is_code_block_conditional: true
        code_block_condition_satisfied: false
        duration_ms: -1.71626201e+12
      }
    }
  }
}
obstacle_wise_root_executions {
  key: "obs_1"
  value {
    child_executions {
      name: "Root"
      is_code_block_conditional: false
      duration_ms: 0
      child_executions {
        name: "Sleep"
        is_code_block_conditional: false
        duration_ms: 0.00244140625
        details: "10"
      }
      child_executions {
        name: "Walk"
        is_code_block_conditional: false
        duration_ms: 0.00244140625
        child_executions {
          name: "Sleep"
          is_code_block_conditional: false
          duration_ms: 0.000244140625
          details: "2"
        }
      }
    }
  }
}
obstacle_wise_root_executions {
  key: "obs_2"
  value {
    child_executions {
      name: "Root"
      is_code_block_conditional: false
      duration_ms: 0
      child_executions {
        name: "Sleep"
        is_code_block_conditional: false
        duration_ms: 0.000244140625
        details: "20"
      }
    }
  }
}

You can format the ObstacleCodePathReport to achieve a better visualization such as
