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...

Installation

To install use pip:

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

Usage

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 (polyglot asdf-like runtime manager)
 # 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 history entries and insert the chosen command
  envx["X_SKIM_KEY_HIST_CWD→"]	= "⎇s" 	#|['escape','s']|  False¦ Search in 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 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
  envx["X_SKIM_KEY_SORT_TOGGLE"]	= "ctrl-r"	#|ctrl-r|False¦ ⎈R binding for 'toggle-sort'
  envx["X_SKIM_KEY_CUSTOM"]     	= None    	#|None| a dictionary of {'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
