Clinical guidelines in primary care
Saving a buffer in Emacs means writing its contents back into the file that was visited in the buffer. Forget that the current buffer has been changed not-modified. With prefix argument C-u , mark the current buffer as changed. When you wish to save the file and make your changes permanent, type C-x C-s save-buffer. After saving is finished, C-x C-s displays a message like this:. If the selected buffer is not modified no changes have been made in it since the buffer was created or last saved , saving is not really done, because it would have no effect.
Instead, C-x C-s displays a message like this in the echo area:. The command C-x s save-some-buffers offers to save any or all modified buffers.
It asks you what to do with each buffer. The possible responses are analogous to those of query-replace :. Save this buffer, then exit save-some-buffers without even asking about other buffers. View the buffer that you are currently being asked about. When you exit View mode, you get back to save-some-buffers , which asks the question again.
C-x C-c , the key sequence to exit Emacs, invokes save-some-buffers and therefore asks the same questions. If you have changed a buffer but you do not want to save the changes, you should take some action to prevent it. Otherwise, each time you use C-x s or C-x C-c , you are liable to save this buffer by mistake. If you do this, none of the save commands will believe that the buffer needs to be saved.
You could also use set-visited-file-name see below to mark the buffer as visiting a different file name, one which is not in use for anything important. Alternatively, you can cancel all the changes made since the file was visited or saved, by reading the text from the file again.
This is called reverting. You could also undo all the changes by repeating the undo command C-x u until you have undone all the changes; but reverting is easier. M-x set-visited-file-name alters the name of the file that the current buffer is visiting.
It reads the new file name using the minibuffer. Then it marks the buffer as visiting that file name, and changes the buffer name correspondingly. It also marks the buffer as "modified" so that C-x C-s in that buffer will save. If you wish to mark the buffer as visiting a different file and save it right away, use C-x C-w write-file. It is precisely equivalent to set-visited-file-name followed by C-x C-s. C-x C-s used on a buffer that is not visiting a file has the same effect as C-x C-w ; that is, it reads a file name, marks the buffer as visiting that file, and saves it there.
If the new file name implies a major mode, then C-x C-w switches to that major mode, in most cases. The command set-visited-file-name also does this. If Emacs is about to save a file and sees that the date of the latest version on disk does not match what Emacs last read or wrote, Emacs notifies you of this fact, because it probably indicates a problem caused by simultaneous editing and requires your immediate attention.
If the value of the variable require-final-newline is t , Emacs silently puts a newline at the end of any file that doesn't already end in one, every time a file is saved or written. If the value is nil , Emacs leaves the end of the file unchanged; if it's neither nil nor t , Emacs asks you whether to add a newline.
The default is nil. This document was generated by Roberto on abril, 2 using texi2html 1. Copying files to "shadows" automatically. Emacs puede actualizar marcas de tiempo en los archivos guardados.
