File Picker with Good Thumbnails and Search

Pikeru is a file picker, file searcher, and image viewer for linux that works on any desktop environment or window manager. It has an xdg-desktop-portal backend that makes it useable with web browsers and anything else that uses portal for file selection.

Special features other filepickers don't have

• Recursive fuzzy semantic file search can search images by visual content in addition to file name.
• Select multiple directories with ctrl, shift, middle-click, or right-click and click Open to view the contents of all of them at the same time.
• Right click an image to view it. Scroll the image to view the next and previous images.
• Cmd menu shows commands specified in ~/.config/pikeru.conf. Click one to run it on the selected files.
• Set a postprocessor script in the config file to convert, resize, compress or do anything else with selected files automatically.

Installation and Usage

First install the dependencies at the bottom of the readme

Install the filepicker and make applications use it

• Run ./install.sh to build and install the filepicker and xdg portal.
• To make firefox use the portal, open about:config and set widget.use-xdg-desktop-portal.file-picker to 1. Chromium-based browsers should use it by default.

What if I want my old filepicker back?

• Run pikeru -d to disable pikeru and restore your old filepicker, and pikeru -e to re-enable pikeru.
• If your xdg-desktop-portal version is older than 1.18, you'll have to delete /usr/share/xdg-desktop-portal/portals/pikeru.portal or remove your $XDG_CURRENT_DESKTOP from that file to disable it.

How to enable semantic search

• This is configured in ~/.config/xdg-desktop-portal-pikeru/config in the indexer section.
• The config requires 3 things in addition to enable = true:
  • a command that prints text associated with a file, like a description or tags
  • a command that checks if the above command can be used, for example checking if an API is online
  • a list of file extensions the above command can handle
• An example configuration using stable diffusioni webui's interrogate API to index your images is included, which uses the indexer/img_indexer.py script in this repo. You'll need to edit the filepath and url to use it.
• Pikeru's xdg portal daemon uses the provided command to build a semantic search index of any directory opened or searched by the filepicker so that next time you search that directory, you can search files by semantic content instead of just file name.
• You can pause the indexer with pikeru -c and resume it with pikeru -b.
• More details are in the man page for xdg-desktop-portal-pikeru.
