occur-x.el adds some extra functionality to occur-mode. It allows the user to
refine any occur mode with extra regexp based filters. Use commands
occur-x-filter to add positive and negative filters.
By default those commands are bind to keys "f" and "k" (from flush and keep).
occur-x-undo-filter to remove filters. Filters are kept if the
buffer is reverted (shortcut "g") or cloned (shortcut "c").
Another useful addition of occur-x to occur-mode is the possibility to
displaying the line numbers in the margin of your choice, instead of "inside"
the occur buffer. This way every match line in the occur buffer is exactly the
same as in the original buffer. Customize variable
occur-linenumbers-in-margin and face
occur-margin-face to your liking. When
displayed in the margin, line numbers won't interfere with the regexps of the
occur-x.el to your load-path and this line to your config file:
(require 'occur-x) (add-hook 'occur-mode-hook 'turn-on-occur-x-mode)
To refine your occur buffer, removing or keeping lines that match any regular expression of your choice, press "k" ([K]eep) or "f" ([F]lush). Press "u" to undo the last filter in the stack.
occur-x-enable to toggle on or off this functionality.
M-x customize-variable RET occur-linenumbers-in-margin to customize where
the line numbers should appear. Type
M-x customize-face RET occur-margin-face if
you want another face for line numbers when they are in a margin.
