In this article, we describe the new advanced stepping menu available in the debugger. These advanced steps provide convenient and automated debugging actions to help you debug your programs. We will see how to build and add new advanced steps, and how to extend the debugger toolbar with your own customized debugging menus. Advanced stepsContinue reading “Advanced stepping and custom debugging actions in the new Pharo debugger”

Ed: your new Emergency Debugger
“What is the nature of your debugging emergency?” —Ed. In this post, we’ll speak about debugging emergencies due to system error handling failures. We’ll cover the current tools available to revert code changes provoking such failures and introduce Ed, the new emergency debugger with improved revert capabilities. What is a debugging emergency? Sometimes when youContinue reading “Ed: your new Emergency Debugger”
On the edge of class rules
Pharo has one simple basic rule: everything is an object. But the objects themselves are not entities living in an abstract universe and do not drink the dew of lilies of the valley for breakfast. They exist in the object memory served by the virtual machine. The virtual machine defines an interface that strictly specifiesContinue reading “On the edge of class rules”
Complishon: efficient heuristics for code completion
A couple of weeks ago I started prototyping a new code completion backend. The one available in Pharo 8.0 is good-enough to complete variables and messages to literal objects. However, the accuracy of the completion was pretty low because auto completion candidates were sorted alphabetically, and this was even producing completion pauses for large images.Continue reading “Complishon: efficient heuristics for code completion”
Why can’t Pharo have constructors?
The other day we were talking about Pablo about pre-tenuring objects when discussing about a couple of papers like this one and this other one. These papers describe the idea of pre-tenuring objects for Java. The main idea being to identify allocation sites in the code (e.g., new MyClass(17, true,someObject)), take statistics about the averageContinue reading “Why can’t Pharo have constructors?”
