How can Smalltalk codes in Squeak be automatically indented ?

RedTigerFish
I was wondering if Squeak has some automatic  indentation function to make
codes in disorder become clean and well-indented in a flash, just like what
we can do in VIM and MS VISUAL STUDIO.

Away from my computer, but search for prettyPrint.

I  choose  the block of codes which I want indented > right click > more >
pretty print.

Nothing happens. Why?

You don't need to select the code you wish to format, it formats the
entire method.

If it is already formatted, pretty print it will appear to have no
effect other than making the method dirty (changed).

Not sure what version of Squeak you're using, but there is also a
hot-key which invokes the pretty print function in the code pane:
Shift+Command+S

Re: How can Smalltalk codes in Squeak be automatically indented ?

This post was updated on .
*1 to: 9 do: [ :i |
    1 to: i do: [ :j |
        Transcript
            show: ('{1} * {2} = {3}' format: {j. i. j * i});
            show: ' '
    ].
    Transcript show: ' '; cr.
].*

The above is well-indented codes. Then I intentionally add or reduce a few spaces, like
this
*1 to: 9 do: [ :i |
             1 to: i do: [ :j |
    Transcript
                 show: ('{1} * {2} = {3} ' format: {j. i. j * i});
                    show: ' '
    ].
            Transcript show: ' '; cr.
].*


Then I use pretty print or pretty print with color, nothing happens.

I recorded a video to illustrate my issue.

I do not understand why "pretty print" does not indent anything.

Oh, I see now, the video makes your question clear :-)

You are working in a workspace, and the menu option "pretty print" is
doing nothing for your selected code in the workspace.

Indeed, this does seem like a bug, because if pretty printing does not
work in a workspace selection, we should not be presenting the option
in a menu.

I do not know if it would be a good idea to have pretty print for
workspace selections (it is not something that I would think to use),
but either way the menu options should agree with the actual behavior.
