actually it should be: ------------- formatStatementCommentsFor: aStatementNode originalSource isNil ifTrue: [ ^ self ]. FormatCommentWithStatements ifFalse: [ ^ self ]. aStatementNode statementComments do: [ :each | | count | count := self newLinesBeforeStartingAt: each first. (count) > 0 ifTrue: [ self newLines: count ] ifFalse: [ codeStream tab ]. codeStream nextPutAll: (originalSource copyFrom: each first to: each last) ] -------------- to allow having comments on top of sections of code.

Ah!
RBConfigurableFormatter class>>settingsOn: is missing one setting ---- (aBuilder setting: #retainBlankLinesBetweenStatements) label: 'Retain blank lines between statements'. ----
As for the comments, I looked at RBConfigurableFormatter>>formatStatementCommentsFor: one idea might be to look at the space between end of the statement and beginning of the comment and if there is newline present then preserve it.
something like -------------------------- formatStatementCommentsFor: aStatementNode originalSource isNil ifTrue: [ ^ self ]. FormatCommentWithStatements ifFalse: [ ^ self ]. aStatementNode statementComments do: [ :each | (self newLinesBeforeStartingAt: each first) > 0 ifTrue: [ self newLine ] ifFalse: [ codeStream tab ].
codeStream nextPutAll: (originalSource copyFrom: each first to: each last) ] ---------------------------
There should be also an accompanying setting #retainBlankLineBeforeComments.

Hi peter
Is it possible to configure formatter to preserve empty lines and line comments?
I do not know :)
e.g. -------------- myMethod someCode. < empty line that I would like to preserve > moreCode. ---------------
But I think that should be customizable.
the formatter also automatically puts comments on the end of the previous statement. e.g. ------ someCode. "a comment" moreCode.
If I recall, the problem is that comments are not a node but an attribute of a node. We should try to fix that. It is not clear where you always want to put them.
---- ends up as ---- someCode. "a comment" moreCode. -----
Both those behaviors seems odd to me.
I've seen empty newlines and line comments in Pharo code... so either I missed some setting or people just don't use the formatter?
I use the formatter and I would like to use it much more systemaitcally.
Thanks, Peter
