AssertionError: Wrong line separators

Created February 20, 2012 16:00

hello,
I have a problem with my plugin Eclipse code formatter   http://plugins.intellij.net/plugin/?idea&id=6546

Document#setText is  failing because sometimes there is a line separator \r\n

is there any better way how to set text to the Document or PsiFile which would handle that separator?

All documents inside IntelliJ IDEA always use the \n line separator. The correct line separator is put in when saving the files.
Please see http://confluence.jetbrains.net/display/IDEADEV/IntelliJ+IDEA+Architectural+Overview for more information.

well, I do not know where those \r\n comes from, because I send \n as a separator to the eclipse formatter.
following code is used:

        VirtualFile virtualFile = psiFile.getVirtualFile();
        FileDocumentManager fileDocumentManager = FileDocumentManager.getInstance();
        Document document = fileDocumentManager.getDocument(virtualFile);
        fileDocumentManager.saveDocument(document); //when file is edited and editor is closed, it is needed to save the text
        document.setText(reformat(virtualFile));
        importOptimization.appendBlankLinesBetweenGroups(document, true);
        fileDocumentManager.saveDocument(document);
