set-input-method versus activate-input-method

[Heime]

Both 'set-input-method' and 'activate-input-method' are functions used to work
with input methods, but they seem to serve different purposes.

Which one should be used in elisp code to change the input method for the current
buffer.

A tip: learn to use Emacs' built-in help facilities:

- Use `C-h f` and `C-h v` (`describe-function` / `describe-variable`) to read the
  doc strings of functions and variables.

- See also `C-h ?` for a quick overview of other help facilities.

- Learn to use the Elisp manual: `C-h i` to access the Info system, then `m` to
  access the menu. Type `Elisp RET` to access the Elisp manual.

- In an Info manual, use `i` to find a topic in its index.

- Look at the source (accessible from the *Help* buffer showing the doc string
  for a function / variable, provided you have the Emacs sources installed). If
  you look at the source for `set-input-method`, you'll notice that it uses
  `activate-input-method` internally, which tells you a lot about the relation
  between the two.
