Based on (now archived) work of @shahinism. Thank you!

The official home of xontrib-fzf-widgets is now at https://github.com/laloch/xontrib-fzf-widgets.

This extension will add some fzf widgets to your xonsh shell that you can bind and use as follows:

• ssh: Search in /etc/ssh/ssh_config or ~/.ssh/config items and issue ssh command on the chosen item.
• history insert: Search in unique history entries and insert the chosen command to the prompt.
• find file: Find one or more files in the current directory and its sub-directories.
• find directory: Similar to the previous one, but intended to only search for directories.

Install the package:

pip install xontrib-fzf-widgets

Enable it by adding fzf-widgets to your ~/.xonshrc file:

xontrib load fzf-widgets

And set your desired keybindings for each widget in ~/.xonshrc file or set it to None to disable it:

$fzf_history_binding = "c-r"  # Ctrl+R
$fzf_ssh_binding = "c-s"      # Ctrl+S
$fzf_file_binding = "c-t"      # Ctrl+T
$fzf_dir_binding = "c-g"      # Ctrl+G

You can find the names of various keys here in python-prompt-toolkit.

Other configuration variables:

• $fzf_find_command: A command used by fzf to search for files.
• $fzf_find_dirs_command: A command used by fzf to search for directories.

$fzf_find_command = "fd"
$fzf_find_dirs_command = "fd -t d"

• If fzf shows garbled file names like [1;38;5;63maur[0m, those extra characters are terminal control codes. That most probably means your file finder is set up to produce colorized output. You can either change your $fzf_find_command and $fzf_find_dirs_command to remove the coloring or add --ansi switch to your $FZF_DEFAULT_OPTS environment variable if you want to preserve the colors. See man 1 fzf for details.
