Pharo 1

Hello,

Im busy with book 1 and I work with version 1
Now this morning I did some changes and save it under a name.

But when I just start up Pharo I see the pharo1.img again without my
changes.
And I also do not see a menu where I can choose which image I want to
use as version 2 of Pharo does.

How can I proceed where I quit with the right image.

Hello Roelof,

That is a disadvantage of having a one-click that opens everywhere.
It contains a script telling the executable which image to open.
You should be able to find your image, and drag it onto the vm
to open. If you just gave it a different name, it is in
Contents\Resources
You might want to change your pharo.ini to point to the right image.

Experienced smalltalkers don’t worry too much about saving (and
disposing of) images. Source code is versioned using Monticello
(a few chapters away) and we use continuous integration to build
new images whenever source code has changed, effectively
giving us a new image to work with each morning.

Thanks,

Next problem.
According to the manual I have to make a new "script"  on the
initializing protocol.
So I did this :

initialize
     | sampleCell width  height n |
     super initialize.
     n:=self CellsPerSide.
     sampleCell := LOCell new.
     width := sampleCell width.
     height := sampleCell height.
     self bounds: (5*5 extent: ((width * n ) @(height * n)) + ( 2  *
self BorderWidth)).
     cells:= Matrix new: n tabulate: [:i :j| self newCellAt: i at: j]

CellsPerSide
      "The number of cells along each side of the game"
           ^ 10

but Pharo 1 makes this :

initialize
     | sampleCell width  height n |
     super initialize.
     n:=self CellsPerSide.
     sampleCell := LOCell new.
     width := sampleCell width.
     height := sampleCell height.
     self bounds: (5*5 extent: ((width * n ) @(height * n)) + ( 2  *
self BorderWidth)).
     cells:= Matrix new: n tabulate: [:i :j| self newCellAt: i at: j]

CellsPerSide
      "The number of cells along each side of the game"
           Nothing more expected ->^ 10

What did I do wring this time ?

Roelof

Two things come to mind:
- method names start with lowercase
  CellsPerSide
- did you make cellsPerSide into a separate method?

you are right, I mistyped that one. I wil change it
> - did you make cellsPerSide into a separate method?

You mean choose all and then type in the text.
nope, if that is the meaning then I misread the manual.

How do I make it part of the initialized protocol then,

Roelof

You can only enter one method at a time.

And methods should be small and be lowercase.

When you write a method in the editor pane and save it, the protocol of the method is the one currently selected in the protocol pane (or 'as yet unclassified' is there is none selected).
In case of mistake, you can always reorganize your methods amongst the different protocols.

Thanks all.
Now trying to solve the last typos and hopefully the games works.

On which os are you?
The new image on mac should be under the ressources folder and the script just opens the default one.
