Jumpy2

A VS Code extension that creates dynamic hotkeys to jump around files across visible panes. It's a new 'Jumpy' but from the original author (Atom package) for VS Code. It works with the major VSC vim extensions and I plan to maintain it.

How to jump

1. Hit shift + enter
2. Choose from your presented labels:
3. Enter two characters.
4. Keep coding!

Watch the demo:

Install

On command line:

code --install-extension davidlgoldberg.jumpy2

Notes

• Works great with or without vim or neovim! See vim/nvim integration below
• Vim modes supported:
  • command mode
  • insert mode
• Recommended key mappings to replace 'f' in vim integration below.
• Recommended key mappings for back and forward below.

Key Bindings

Defaults

• Enter jump mode
  • shift + enter
• Enter selection mode
  • shift + alt + enter
• Reset first character entered
  • backspace
• Cancel/exit jump mode (any of the following)
  • shift + enter
  • enter
  • esc
  • space

Jump back and forward

Did you know VS Code has built in backwards and forward navigation functionality? You should probably map that to a hotkey for Jumpy! I currently use the backspace key which overrides the default boring backspace functionality from vim (while in normal mode only of course).

For example with vim Edit this in your keybindings.json file:

    {
        "key": "backspace",
        "command": "workbench.action.navigateBack",
        "when": "editorTextFocus && vim.active && !inDebugRepl && vim.mode == 'Normal'"
    },
    {
        "key": "shift+backspace",
        "command": "workbench.action.navigateForward",
        "when": "editorTextFocus && vim.active && !inDebugRepl && vim.mode == 'Normal'"
    },

Custom set of keys to use (easier to type / faster?)

"jumpy2.customKeys": {
    "type": "array",
    "default": "fjdkslaghrueiwoncmv",
    "description": "Default characters to use"
},

The default might be easier for beginners. It is also probably better for larger screens (more labels before jumpy has to resort to utliizing uppercase letters).

"jumpy2.customKeys": {
    "type": "array",
    "default": "abcdefghijklmnopqrstuvwxyz",
    "description": "Default characters to use"
},

Colors & Border

To override Jumpy's default label colors (black on green) try this In your VS Code's settings.json file:

"workbench.colorCustomizations": {
  "jumpy2.beaconColor": "#ff0000af", // transparent red

  "jumpy2.labelFontColor": "#000000", // black font
  "jumpy2.labelBackgroundColor": "#ff0000", // red bg
  // In this example you would probably want to change the border to black if NOT using checkered-mode (below)
  // (useful when you have aggressive regexes with adjacent labels!)
  "jumpy2.labelBorderColor": "#ff0000", // red border

  // Checkered-mode (or Chess-mode) is the new default setting which alternates colors (like zebra stripes).
  // These styles are optional while using checkered-mode:
  "jumpy2.checkered_labelFontColor": "#ff0000", // red font
  "jumpy2.checkered_labelBackgroundColor": "#000000", // black bg
  "jumpy2.checkered_labelBorderColor": "#000000", // black border
},

However, it is probably wise to leave the defaults, and instead scope this to a theme or wildcarded (modified from VS Code's examples like so:

"workbench.colorCustomizations": {
  // NOTE: not all dark and light themes are conveniently labeled "dark" or "light" like this.
  // In that case, you can specify per theme, or again, just leave Jumpy's default or override the default with the example above.
  "[*Dark*]": {
    "jumpy2.labelFontColor": "#000000",
    "jumpy2.labelBackgroundColor": "#FFFFFF",
    "jumpy2.labelBorderColor": "#FF0000",
    "jumpy2.beaconColor": "#FF0000AF",
  },
  "[*Light*]": {
    "jumpy2.labelFontColor": "#FFFFFF",
    "jumpy2.labelBackgroundColor": "#000000",
    "jumpy2.labelBorderColor": "#FF0000",
    "jumpy2.beaconColor": "#FF0000AF",
  }
},

Vim integration

(see neovim below if interested)

Override vim's extension level backspace

If you want the backspace key to work as the jumpy "reset" command you must define a "user" level keybindings override in keybindings.json to override vim's "extension" level keybinding:

{
    "key": "backspace",
    "command": "jumpy2.reset",
    "when": "jumpy2.jump-mode && editorTextFocus"
}

(feel free to bind it to another key as well)

Bind 'f' and/or 'F' key

if f vim functionality is desired: open settings as json and add:

  "vim.normalModeKeyBindingsNonRecursive": [
    {
      "before": ["f"],
      "commands": ["jumpy2.toggle"]
    },
    {
      "before": ["F"],
      "commands": ["jumpy2.toggleSelection"]
    }
  ],

Neovim Integration

NOTE: I haven't fully configured neovim but used it successfully for a while with the following:

{
  "key": "f",
  "command": "jumpy2.toggle",
  "when": "neovim.mode =~ /^normal$|^visual$/ && !jumpy2.jump-mode && editorTextFocus"
},
{
  "key": "escape",
  "command": "jumpy2.exit",
  "when": "neovim.init && jumpy2.jump-mode && editorTextFocus"
}

for back and forward functionality with neovim:

{
  "key": "backspace",
  "command": "workbench.action.navigateBack",
  "when": "editorTextFocus && !inDebugRepl && neovim.mode != 'insert'"
},
{
  "key": "shift+backspace",
  "command": "workbench.action.navigateForward",
  "when": "editorTextFocus && !inDebugRepl && neovim.mode != 'insert'"
}

Fun

See your achievements(!)

command palette (usually command/ctrl+shift+p) -> Jumpy: Show Jumpy Achievements (career jumps) (a real ninja would bind it to a key though)

You can also disable this pop up if you're an uber important 1337 10x h4x0r that can't afford to hot key a tab closed once a year...

  "jumpy2.achievements.active": false,

Emojis (Subtly useful)

Change the 'jumper' set (emojis) in your VS Code's settings.json

add:

  "jumpy2.jumperEmojis.jumperSet": ["🐒"],

The above tells jumpy to use the monkey emoji exclusively.

Of course you can turn these off too. If you have no soul.

  "jumpy2.jumperEmojis.active": false,

Known Issues

• Can not jump to treeview or tabs.
