Fomratting won't work correctly when save xtext resource programmatically AbstractFormatter2 [message #1854107]

When I try to save xtext resource programmatically formatting won't work correctly? if I apply manual formatting from editor it works.

We are extending AbstractFormatter2.
Before saving i move few object in emf and save.
Do semantic model differ when we save resource programmatically?

Any input will be appreciated.

Thanks

in doubt it is a bug. can you provide a reproducing unit test?
did you compare if the textedits calculated are the same?

@Christian Dietrich Thank you quick reply I did some comparison i found slight difference but why its happening not sure.

Basically what i was trying to do was , move few object from one container to other container and save programmatically.

PFA of report. Left hand side is manual formatting and right hand side is save programmatically(ITextReplacers).

In our formatter if we see anything - we append few spaces.

Formatting works through editor, but not with programmatic save.

Thanks

it looks like saving formats only the changed regions and not the complete file
also check what is the diff between the FormatterRequests the formatter is called with in both cases
=> would be nice to have a reproducing unit test

@Christian Dietrich Thank you, will check FormatterRequest for both manual and programmatic save.

RCA was when i was saving resource I was not passing save option map with explicitly stating formatting, though the formatter get called but it was not getting formatted correctly.
val saveOption = SaveOptions.newBuilder.format.options.toOptionsMap.

@Christian Dietrich Thank you
