Is it possible to create a regexp that excludes a string? For example, I want to create a regexp that accepts a set of strings with
*.*helm.**except a few ones such as
*helm help*. It means,
*helm help* should be excluded. I want this regexp functionality because I set
display-buffer-alist to position Helm windows where I like it to be:
(add-to-list 'display-buffer-alist `("*.*helm.**" (display-buffer-in-side-window) (inhibit-same-window . t) (window-height . 0.4)))
However, doing so would prevent a Helm buffer by default displayed in fullscreen, like
*helm help* buffer.
