Bug 3970 [preferences] UI needed to define the default line delimiters for new files (1GFIOAX)
When creating a new file we currently use the line delimiter returned form System.getProperties("line.delimiter"). But this is not whay a user always wants. Consider the following sceanrio: - Unix and Windows work station used to develop a Unix product / program. - the Windows work stations are used as X terminals and to run Eclipse (since PC are cheaper than Unix boxes). - even if the new file is created on Windows it should have Unix line delimiters since the end product is a Unix product. There should be a UI (Preference) to define the line delimiter for new files. Possible values are: - Dos / Windows - Mac - Unix - default platform line delimiter. The UI should be provided by the Workbench since all plugins should use the same line delimiter for new files. NOTES:
