Create a list from ALIST-ENTRY, which can be used with @code{mixed-text-file} for example to create key-value configuration file or shell script. PREFIX is the string to prefix the key-value pair with. For example, @code{"export"} will return @code{'("export" KEY SEP VALUE)}, where KEY is the first element of ALIST-ENTRY, and VALUE is the second element of ALIST-ENTRY. SEP is the separator between the key and the value. SUFFIX is the optional argument, default to newline. Different things will happen depending on the value of VALUE: @itemize @bullet @item If VALUE is #f, ignore everything in the entry and just return an empty list. @item If VALUE is #t or not provided (empty list), ignore the VALUE and SEP and just return a list of PREFIX and KEY followed by a SUFFIX. @item If VALUE is a flat list, it will get added to the resulting list. If not flat the exception will be raised. @item If VALUE is not a list (string, file-like object, etc), return a list of PREFIX, KEY, SEP and VALUE followed by a SUFFIX. The following code @lisp ((alist-entry->mixed-text "export " "=") '("EDITOR" . "emacsclient")) ((alist-entry->mixed-text "export " "=") '("EDITOR" . #t)) ((alist-entry->mixed-text "export " "=") '("EDITOR")) ((alist-entry->mixed-text "export " "=") '("EDITOR" . #f)) ((alist-entry->mixed-text "export " "=") '("EDITOR" . ("emacsclient" "vim"))) @end lisp would yield @example ("export " "EDITOR" "=" "emacsclient" " ") ("export " "EDITOR" " ") ("export " "EDITOR" " ") () ("export " "EDITOR" "=" "emacsclient" "vim" " ") @end example
