(guix-eval-in-repl): Use it. Add optional 'operation-buffer' argument. * emacs/guix-base.el (guix-update-after-operation): New variable. (guix-switch-to-buffer, guix-list-or-info-buffer-p, guix-buffers, guix-update-buffers-maybe): New procedures. (guix-set-buffer): Use 'guix-switch-to-buffer'. Add optional 'no-display' argument. (guix-process-package-actions, guix-delete-generations, guix-switch-to-generation): Add optional 'operation-buffer' argument. * emacs/guix-info.el (guix-package-info-insert-action-button, guix-generation-info-insert-number, guix-generation-info-insert-current): Adjust for using operation buffer. * emacs/guix-list.el (guix-list-execute-package-actions, guix-generation-list-switch, guix-generation-list-execute): Likewise. --- emacs/guix-backend.el | 12 ++++++-- emacs/guix-base.el | 83 +++++++++++++++++++++++++++++++++++++++++++-------- emacs/guix-info.el | 12 ++++---- emacs/guix-list.el | 6 ++-- 4 files changed, 89 insertions(+), 24 deletions(-) diff --git a/emacs/guix-backend.el b/emacs/guix-backend.el index 0ca9083..a19d42f 100644 --- a/emacs/guix-backend.el +++ b/emacs/guix-backend.el @@ -272,6 +272,9 @@ additional internal REPL if it exists." ;;; Evaluating expressions +(defvar guix-operation-buffer nil + "Buffer from which the latest Guix operation was performed.") + (defun guix-make-guile-expression (fun &rest args) "Return string containing a guile expression for calling FUN with ARGS."
