The issue this code solved was that setting the proxy icon via represented file before a file actually exists on disk would lead to no icon so we would have to update it again after a successful save.
This however is already done (by the save callback passed in).
The text view needs to do a little work before saving a document (serialize folded text) and with the window as part of the user data, we can now skip that for text views in windows for which documents are not going to be saved.
This is not an ideal solution; long-term saving will be moved up to the DocumentWindowController which has the full view of all documents and text views.
__attribute__((format(...))) was added to NSAlert's class-based initializer in 10.7, and due to using string objects instead of literals as informative text, Clang is unable to guarantee the safety of the formatter, and, as such, issues a warning.
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.
A minor caveat is that if there are encoding or newline (folder specific) settings in effect for the chosen path, these trump what’s selected in the save dialog.
If we wish to solve this, the best would be to update the options (shown in the save panel) based on selected folder/filename (and the settings in effect for that).
This closes issue #163.
