skim (fuzzy finder) integration into xonsh (shell)
Sets up keybinds to search various type of data: dirs/files, history of commands/CWDs/dirs, ssh hosts...

Install

xpip install -U xontrib-skim
# or: xpip install -U git+https://github.com/eugenesvk/xontrib-skim

Use

Supported data sources:

• xonsh history of commands (and their frequency)
• xonsh history of commands' CWDs (and the frequency of commands started here)
• zoxide's history of dirs
  CWDs/dirs support multi-selection (with proper escape-quoting) as well as cd-ing to the selected dir in-place
• files in the current directory and its sub-directories
• dirs in the current directory and its sub-directories
• ssh hosts from /etc/ssh/ssh_config, ~/.ssh/config, ~/.ssh/known_hosts

This xontrib requires sk (or sk-tmux) to be in PATH. If it's added to PATH via another xontrib (e.g, you installed it via Homebrew and use xontrib-homebrew), then you should load this xontrib after the one setting PATH

1. Add the following to your .py xontrib loading config and import it in your xonsh run control file (~/.xonshrc or ~/.config/rc.xsh):

from xonsh.xontribs 	import xontribs_load
from xonsh.built_ins	import XSH
envx = XSH.env

xontribs = [ "skim", # Initializes skim (Fuzzy Finder)
 # your other xontribs
]
# ↓ optional configuration variables (use `False` to disable a keybind)
if 'skim' in xontribs: # Configure skim only if you're actually loading it
  #Config var                    Value   ≝Default          ¦Alt_cmd	  Comment
  envx["X_SKIM_KEY_HIST"     ] = "⎈  s" #≝c-s             ¦False Search in xonsh 's history entries      and ⎀insert the chosen command
  envx["X_SKIM_KEY_HIST_CWD→"] = "  ⎇s" #≝['escape','s']  ¦False Search in xonsh 's history entries' CWD and →CD to  the selected item (if exists, do nothing otherwise)
  envx["X_SKIM_KEY_HIST_CWD" ] = "⎈⎇s" #≝['escape','c-s']¦False Search in xonsh 's history entries' CWD and ⎀insert the selected item(s)
  envx["X_SKIM_KEY_HIST_Z→"  ] = "  ⎇z" #≝['escape','z']  ¦False Search in zoxide's history entries      and →CD to  the selected item (if exists, do nothing otherwise)
  envx["X_SKIM_KEY_HIST_Z"   ] = "⎈⎇z" #≝['escape','c-z']¦False Search in zoxide's history entries      and ⎀insert the selected item(s)
  envx["X_SKIM_KEY_FILE"     ] = "⎈  f" #≝c-f             ¦False Find files in the current directory and its sub-directories
  envx["X_SKIM_KEY_DIR"      ] = "  ⎇f" #≝['escape','f']  ¦False Find dirs  in the current directory and its sub-directories
  envx["X_SKIM_KEY_SSH"      ] = "⎈  b" #≝c-b             ¦False Run 'ssh HOST' for hosts in /etc/ssh/ssh_config, ~/.ssh/config, ~/.ssh/known_hosts

  # run to see the allowed list for ↑: from prompt_toolkit.keys import ALL_KEYS; print(ALL_KEYS)
  # Alt is also supported as either of: a- ⎇ ⌥ (converted to a prefix 'escape')
  # Control symbols are also supported as either of: ⎈ ⌃
  # ↓ are key bindings for the skim binary itself, not this xontrib, so use skim rules https://github.com/lotabout/skim#keymap
  #Config var                  	  Value     ≝Default¦Alt_cmd  Comment
  envx["X_SKIM_KEY_SORT_TOGGLE"	] = "ctrl-r" #≝ctrl-r ¦False    ⎈R binding for 'toggle-sort'
  envx["X_SKIM_KEY_CUSTOM"     	] = None     #≝None   ¦{'key':'action'}
  envx["X_SKIM_NO_HEIGHT"      	] = True     #≝True   ¦False  disable `--height` to fix a skim bug
  envx["X_SKIM_NO_SORT"        	] = True     #≝True   ¦False  disable history sorting
  envx["X_SKIM_CMD_FRQ"        	] = True     #≝True   ¦False  add ∑command runs for a given command
  envx["X_SKIM_CMD_FRQ_MIN"    	] = 5        #≝5      ¦       hide frequency numbers below this
  envx["X_SKIM_CWD_FRQ"        	] = True     #≝True   ¦False  add ∑command runs at a given CWD
  envx["X_SKIM_CWD_FRQ_MIN"    	] = 5        #≝5      ¦       hide frequency numbers below this
  envx["X_SKIM_CMD_FIND"       	] = "fd -t f -t l" #≝None      command used by skim to search for files
  envx["X_SKIM_CMD_FIND_DIR"   	] = "fd -t d     " #≝None      command used by skim to search for directories
  envx["X_SKIM_DIR_VIEW"       	] = "ls -F --color=always {2..}" #≝None  preview function for Dir lists
  envx["SKIM_DEFAULT_OPTIONS"  	] = "--ansi --preview-window=right:40%:wrap" #≝None   other options to pass to skim

xontribs_load(xontribs) # actually load all xontribs in the list

2. Or just add this to your xonsh run control file

xontrib load skim # Initializes skim (fuzzy finder)
# configure like in the example above, but replace envx['VAR'] with $VAR
$X_SKIM_KEY_HISTORY	= "c-s" # ...

Examples

• cd to a path in-place without losing the command you've already typed in the prompt!

  1. Press ⎇s (for command history CWD's) or ⎇z (for zoxide's history) to launch fuzzy finder of your favorite dirs
     

  2. Find the correct dir and insert it
     

  3. The prompt is updated in the background, reflecting the dir change and preserving the command
     

• Find fils/dirs in xonsh-completed paths: type cd ~/Mus; hit ⎈F to limit your file search to ~/Music

• Find files with ⎈F and dirs with ⎇F

envx["X_SKIM_KEY_FILE"]	= "⎇f"
envx["X_SKIM_KEY_DIR"] 	= "⎈f"

• Insert multiple paths with home row cursor keys
  ⎇J to toggle and ▼
  ⎇K to toggle and ▲

  envx["X_SKIM_KEY_CUSTOM"]	= {
    'alt-j':'toggle+down'  	,
    'alt-k':'toggle+up'    	}

Known issues

• skim doesn't clear the screen properly when --height is set due to a bug. At the moment this flag is disabled via X_SKIM_NO_HEIGHT
• skim sometimes prints extraneous text symbols, e.g., when searching history, maybe due to this bug or something else
• skim might bug in tmux on some system/terminals bug1, bug2
• toggle-sort (and X_SKIM_KEY_SORT_TOGGLE) doesn't seem to be supported in skim, ls | sk --bind=pgdn:toggle-sort also fails
• to remove extra ?[38;5;26mFOLDER from output, add --ansi to $SKIM_DEFAULT_OPTIONS or disable colors in your $X_SKIM_CMD_FIND/DIR filter (e.g., fd -t d -c never)
• ⎈/⎇f conflict with xontrib-output-search's defaults
