Removed the ability to specify wether documents should open in current window or a new window — all documents opened via this API will go through the same algorithm to find where the documents should end up (more choice is just adding confusion and complexity).
Since everything about session is now contained in the DocumentController class there is no need for invoking this from elsewhere and thus no need for the previous indirection.
Previously if the custom name was set before the display name was requested, it would not allocate an untitled counter, but if set later, it would (effectively) not release the counter already allocated.
We didn’t actually use the file itself, only its parent directory, and there are several places we want SCM info for an untitled file’s project directory, so removing the need for a file simplifies things.
Xcode does some weird stuff while saving, it renames the existing file (twice), having it end up in some staging area with a UUID as filename, and then disappear.
Previously TextMate would track these renames, now it waits up to one second for a new file to appear using the old file’s path.
There is a minor functional change in that the custom callback type uses event loop signaling that makes it safe to trigger the callback from a thread. This should however not be necessary for timers (which are all setup on the main thread).
This happens e.g. if we do ‘ls|mate’ — here we do have content which got a charset and newline mode assigned during “load”, but from the user’s POV he is saving a new file (if he saves the buffer) so should get his configured encoding.
There is also a new document_t::encoding_for_save_as_path which returns the encoding that would be used for the document, if saved at the given path. If the document was loaded from disk, it will return the encoding used during load, otherwise it will check tmProperties for which encoding should be used for the path provided. Save dialog for untitled documents will be pre-populated with the result of the above function.
