"ProfStef"
Quentin Ducasse.
-Hello, everyone.
In this lesson, we are going to look at the tool named ProfStef.
Basically, to launch it,
all you have to do is to write "ProfStef go" in a Playground
and just highlight it
and do it.
This opens the tool. There is some presentation.
Basically, this tool is there to help you learn Pharo by yourself.
What you can do is, for each lesson,
you can see here that there are 29 lessons,
you will have some explanation,
then a "ProfStef next" to access the next lesson.
What we can do is highlight it, right click it and do it
to go to the next lesson.
So, once again, you have some explanations.
These are explanations on the "Do it" command.
What we can do, for example,
is select the "GTPlayground open", right-click and do it.
This opens a Playground.
What we can do next is do it to the next lesson
with "ProfStef next".
Do it.
This is an explanation of the "Print it" command.
You can highlight, right-click and print it this time
so it shows a 3.
We can do the same thing with other expressions.
I will let you try those by yourself.
Let's go to the next lesson, do it.
And these are some explanations of the "Inspect it" command, so this one.
Basically, if we highlight the "1/2",
it opens the Inspector on a fraction, so half.
Basically, the flow of this tool is to have some explanation.
Try it yourself
and then, inspect and browse all the different commands Pharo offers.
I would really encourage you to look at this tool
and try commands,
maybe do the 29 lessons if you are motivated.
