I have some code that uses
flet to temporarily change the behaviour of functions.
;; prevent changing the window (flet ((pop-to-buffer (buffer &rest args) (switch-to-buffer buffer))) (compilation-next-error-function n reset))
However, Emacs' byte compiler gives a warning:
In ag/next-error-function: ag.el:103:7:Warning: `flet' is an obsolete macro (as of 24.3); use either `cl-flet' or `cl-letf'.
cl-flet works differently and doesn't suit some use cases, and I believe this is one of those cases.
The options I can see are:
What is the best approach?
