Save Ivy file completions to Dired18 Nov 2017
ivy-occur (C-c C-o) is one of the coolest
features in ivy. It allows you
to save your current search into a new buffer. This has many uses:
- get a full overview of all candidates
- many useful modal bindings (q, j, k, f) and mouse support
- ability to manipulate candidates as text
- save the search for later, with the option to refresh the search with g
- go over candidates as a TODO list, using C-d to remove elements
Everything above works for any
ivy-read session. But the most
powerful features come into play when
ivy-occur gets customized for
a specific collection.
ivy-occur for grep-like functions
(ivy-set-occur 'swiper 'swiper-occur)
Thanks to this default customization, the resulting
swiper* buffer is in
ivy-occur-grep-mode which inherits from
grep-mode. Additionally, you can use
ivy-wgrep-change-to-wgrep-mode C-x C-q to edit the result
in-place - pressing C-x C-s will save the changes.
Similar customizations are available for
(ivy-set-occur 'ivy-switch-buffer 'ivy-switch-buffer-occur)
This makes C-c C-o open your candidates in the powerful
ibuffer, which adds additional info to your buffer list and allows
you to manipulate buffers easily.
For instance, to delete all matching buffers you can do C-c C-o tD.
The source code is short enough to be included here:
(defun ivy-switch-buffer-occur () "Occur function for `ivy-switch-buffer' using `ibuffer'." (ibuffer nil (buffer-name) (list (cons 'name ivy--old-re))))
The interface is quite simple:
ivy-occur is responsible for
generating a new buffer, and the occur function
ivy-switch-buffer-occur is to fill that buffer with useful
info, based on the current search parameters like
This is a brand new feature that works for
counsel-fzf (which itself is quite new, thanks to
@jojojames for contributing it).
Since these functions are used to complete file names, we obviously
ivy-occur to open a Dired buffer.
To delete all
*.elc files in the current folder do:
- C-x C-f
elc$C-c C-o tDy.
To copy all Org files in a Git project to some directory do:
org$C-c C-o tC.
To get a list of videos to watch do:
I can further e.g. mark 3 files with m and use r
to send these 3 files to
vlc as a list. See this
post for my dired setup
that makes r work this way.
You can remove some files afterwards with the usual D or dx. And to redisplay the buffer use g.
I hope you like the new feature. I had a really good few hours figuring out how it should work exactly. Please consider joining my 72 patrons to give me the opportunity to work on Free Software a lot more. Happy hacking!
