  :tag "Pyre")

(defcustom lsp-pyre-command '("pyre" "persistent")
  "Pyre command."
  :group 'lsp-pyre
  :risky t
  :type 'list)

(defun lsp-pyre-activate-p (file-name _mode)
  "Check if FILE-NAME is part of a Pyre project.
That is, if there is a .pyre_configuration(.local)? file in the folder hierarchy."
  (or (locate-dominating-file file-name ".pyre_configuration.local")
      (locate-dominating-file file-name ".pyre_configuration")))
