This library shows a sticky header at the top of the window. The header shows which definition the top line of the window is within. It’s intended as a simple alternative to semantic-stickyfunc-mode. It’s especially helpful when, for example, browsing a list of occur results: when a line is in the middle of a definition, and the top of the definition is beyond the top of the window, topsy shows what definition the line is in.

Mode-specific functions may be added to topsy-mode-functions.

NOTE: For Org mode buffers, please use org-sticky-header.

This library is not on MELPA yet.

The recommended way to install is with quelpa-use-package, like this:

;; Install and load `quelpa-use-package'.
(package-install 'quelpa-use-package)
(require 'quelpa-use-package)

(use-package topsy
  :quelpa (topsy :fetcher github :repo "alphapapa/topsy.el")
  :hook (prog-mode . topsy-mode))

Put topsy.el in your load-path, then:

(require 'topsy)

(add-hook 'prog-mode-hook #'topsy-mode)

Run command topsy-mode. You may add it to appropriate hooks, such as prog-mode-hook.

• You can customize settings in the topsy group.

Bug reports, feature requests, suggestions — oh my!

There is currently only one function in topsy-mode-functions, one which returns the line that beginning-of-defun goes to. It should be useful in many major modes, but suggestions for additional, mode-specific functions are welcome.
