after-save-file (augments, and augmentable only) in text:file-mixin

Called just after the editor is saved to a file.

The argument to the method originally specified whether the save was successful, but failures now trigger exceptions such that the method is not even called. Consequently, the argument is always #t.

See also can-save-file? and on-save-file.

• (send a-text:file-mixin after-save-file void

  Checks if the newly saved file is write-only in the filesystem. If so, locks the editor with the lock method. Otherwise unlocks the buffer

  For each canvas returned from get-canvases it checks to see if the canvas%'s get-top-level-window matches the frame:editor<%> interface. If so, it calls set-label with the last part of the filename (ie, the name of the file, not the directory the file is in).
