Excursions (GNU Emacs Lisp Reference Manual)
31.3 Excursions. It is often useful to move point temporarily within a localized portion of the program. This is called an excursion, and it is done with the save-excursion special form. This construct remembers the initial identity of the current buffer, and its value of point, and restores them after the excursion completes. It is the ...
save-excursion (Programming in Emacs Lisp)
3.10 save-excursion. The save-excursion function is the final special form that we will discuss in this chapter.. In Emacs Lisp programs used for editing, the save-excursion function is very common. It saves the location of point, executes the body of the function, and then restores point to its previous position if its location was changed.
Elisp: is this an expected behavior of save-excursion?
Think of it this way: we indent the code by. delete all leading blanks. insert leading blanks as necessary. So, the answer is: this is the expected behavior. More to the implied gist of your question, there is no reason to rely on the specific position of the point after indentation if the point was adjacent to whitespace which was normalized.
append save-excursion (Programming in Emacs Lisp)
The body of the let expression in append-to-buffer consists of a save-excursion expression. The save-excursion function saves the location of point, and restores it to that position after the expressions in the body of the save-excursion complete execution. In addition, save-excursion keeps track of the original buffer, and restores it.
GNU Emacs Lisp Reference Manual
Likewise, save-excursion does not restore window-buffer correspondences altered by functions such as switch-to-buffer. One way to restore these correspondences, and the selected window, is to use save-window-excursion inside save-excursion (see section Window Configurations). The value returned by save-excursion is the result of the last of ...

3.10 save-excursion
3.10 save-excursion. The save-excursion function is the fourth and final special form that we will discuss in this chapter.. In Emacs Lisp programs used for editing, the save-excursion function is very common. It saves the location of point and mark, executes the body of the function, and then restores point and mark to their previous positions if their locations were changed.
Why save-excursion doesn't save point position ...
save-excursion stores a marker, not the 'byte' number. When you kill the line where point is, this marker gets replaced to the beginning of the line. (From: Andreas Politz) From Elisp Manual [ (info "(elisp)Excursions") ]: Warning: Ordinary insertion of text adjacent to the saved point value relocates the saved value, just as it relocates all ...
elisp
Q: is there an alternative to save-excursion that only saves/restores point? When writing elisp functions, I often need to save point, do some stuff in the current buffer, and then restore point. I had always used save-excursion for doing so, but the docstring notes that it will: Save point, mark, and current buffer; execute BODY; restore those ...

How can I start learning Emacs Lisp?
save-excursion; save-restriction; hooks; advising functions; with-current-buffer; Once you understand these, instead of spending all your time reading the ELisp reference, think of simple problems you have with Emacs that you want to write and try solving them with Elisp. You'll likely need help on some of the steps, and that's where Google can ...

Use M-: to evaluate any Emacs Lisp expression and print the result. I personally use this constantly. Use C-x C-e to evaluate the previous s-expression in the buffer. I personally never use this. See next binding. Use C-M-x to evaluate the current top-level s-expression. I use this to re-apply defvar and defun declarations.; There is a REPL available by M-x ielm.

The template for code using save-excursion is simple: (save-excursion. body …) The body of the function is one or more expressions that will be evaluated in sequence by the Lisp interpreter.

Arrival in Vladimir and transfer to the starting point of the excursion. City tour of Vladimir - Vladimir was once the mediaeval capital of the Russian state and so is an important city in terms of Russian history. The highlights of this tour include: Dormition Cathedral - the main cathedral of the city. For over 200 years this cathedral held the revered Our Lady of Vladimir Icon, which ...
Narrowing (GNU Emacs Lisp Reference Manual)
If you use both save-restriction and save-excursion together, save-excursion should come first (on the outside). Otherwise, the old point value would be restored with temporary narrowing still in effect. If the old point value were outside the limits of the temporary narrowing, this would fail to restore it accurately. Here is a simple example ...
