Crashing since 2022.1 (with workaround for OS X)

[Alexsey]

Just installed the WebStorm 2022.1 EAP. It seems that the old API is not working anymore :(

Hey guys, really enjoyed this plugin prior to 2022.1, will this be fixed or is it not possible with the new API?

[Alexsey]

My Java and IDEA API knowledge are too bad to fix this in a reasonable time :(
I do hope that someday @andreycizov would find some time to fix this. Meanwhile, I've written a workaround for OS X with Hammerspoon I can share

To run it just follow instructions from the official Hamerspoon docs on Hello World but use the snippet from below. Please, ask if something wouldn't work

Code

-- the replacement of the unsupported since 2022.1 plugin "Partial Navigation"

-- Setup block
local ideName = "WebStorm" -- change this to match your IDE name
local partialNavigateLines = 10 -- number of lines per PageUp / PageDown
local scrollSpeed = 4 -- page scroll speed on press & hold. More is faster
local isPartialNavigationActive = true -- move caret by partialNavigateLines
local isPartialNavigationWithScrollActive = false -- move caret and scroll by partialNavigateLines
local isPartialScrollActive = false -- scroll by partialNavigateLines

-- Initialization blocks
local keyRepeatDelay = hs.eventtap.keyRepeatDelay() -- https://github.com/Hammerspoon/hammerspoon/issues/1082#issuecomment-281163614
local function repeatKey (times, mods, key)
  return function ()
    for _ = 1, times do
      hs.eventtap.keyStroke(mods, key, keyRepeatDelay)
    end
  end
end

local function remapAndRepeatHotkey (map)
  local fromKey = map.from.key
  local fromMod = type(map.from.mod) == "string" and {map.from.mod} or map.from.mod or {}
  local toKey = map.to.key
  local toMod = type(map.to.mod) == "string" and {map.to.mod} or map.to.mod or {}

  return hs.hotkey.new(
    fromMod, fromKey,
    repeatKey(partialNavigateLines, toMod, toKey), nil, repeatKey(scrollSpeed, toMod, toKey)
  )
end

-- the list of available "key" values https://www.hammerspoon.org/docs/hs.keycodes.html#map
-- the list of available "mod" values https://www.hammerspoon.org/docs/hs.hotkey.html#assignable
local partialPageUp = remapAndRepeatHotkey({
  from = {key = "pageup"},
    to = {key = "up"},
})
local partialPageDown = remapAndRepeatHotkey({
  from = {key = "pagedown"},
    to = {key = "down"},
})
local partialPageUpWithSelection = remapAndRepeatHotkey({
  from = {mod = "shift", key = "pageup"},
    to = {mod = "shift", key = "up"},
})
local partialPageDownWithSelection = remapAndRepeatHotkey({
  from = {mod = "shift", key = "pagedown"},
    to = {mod = "shift", key = "down"},
})
local partialPageUpAndScroll = remapAndRepeatHotkey({
  from = {mod = "ctrl", key = "pageup"},
    to = {mod = "ctrl", key = "up"},
})
local partialPageDownAndScroll = remapAndRepeatHotkey({
  from = {mod = "ctrl", key = "pagedown"},
    to = {mod = "ctrl", key = "down"},
})
local partialPageUpAndScrollWithSelection = remapAndRepeatHotkey({
  from = {mod = {"ctrl", "shift"}, key = "pageup"},
    to = {mod = {"ctrl", "shift"}, key = "up"},
})
local partialPageDownAndScrollWithSelection = remapAndRepeatHotkey({
  from = {mod = {"ctrl", "shift"}, key = "pagedown"},
    to = {mod = {"ctrl", "shift"}, key = "down"},
})
local partialPageUpScroll = remapAndRepeatHotkey({
  from = {mod = "alt", key = "pageup"},
    to = {mod = "alt", key = "up"},
})
local partialPageDownScroll = remapAndRepeatHotkey({
  from = {mod = "alt", key = "pagedown"},
    to = {mod = "alt", key = "down"},
})

local function enablePartialNavigation ()
  partialPageUp:enable()
  partialPageDown:enable()
  partialPageUpWithSelection:enable()
  partialPageDownWithSelection:enable()
end

local function disablePartialNavigation ()
  partialPageUp:disable()
  partialPageDown:disable()
  partialPageUpWithSelection:disable()
  partialPageDownWithSelection:disable()
end

local function enablePartialNavigationWithScroll ()
  partialPageUpAndScroll:enable()
  partialPageDownAndScroll:enable()
  partialPageUpAndScrollWithSelection:enable()
  partialPageDownAndScrollWithSelection:enable()
end

local function disablePartialNavigationWithScroll ()
  partialPageUpAndScroll:disable()
  partialPageDownAndScroll:disable()
  partialPageUpAndScrollWithSelection:disable()
  partialPageDownAndScrollWithSelection:disable()
end

local function enablePartialScroll ()
  partialPageUpScroll:enable()
  partialPageDownScroll:enable()
end

local function disablePartialScroll ()
  partialPageUpScroll:disable()
  partialPageDownScroll:disable()
end

-- although idePartialNavigator is not used anywhere,
-- do NOT delete this variable and do NOT make it local -
-- otherwise, Lua would garbage collect the watcher in a minute.
-- The main code of this handler will be executed every time the IDE would be focused or unfocused
idePartialNavigator = hs.application.watcher.new(function(name, event)
  -- skip if no window is focused
  if name == nil then return end

  -- skip if it's not the IDE window
  if not string.find(name, ideName) then return end

  if event == hs.application.watcher.activated then
    if isPartialNavigationActive == true then
      enablePartialNavigation()
    end
    if isPartialNavigationWithScrollActive == true then
      enablePartialNavigationWithScroll()
    end
    if isPartialScrollActive == true then
      enablePartialScroll()
    end
  elseif event == hs.application.watcher.deactivated then
    if isPartialNavigationActive == true then
      disablePartialNavigation()
    end
    if isPartialNavigationWithScrollActive == true then
      disablePartialNavigationWithScroll()
    end
    if isPartialScrollActive == true then
      disablePartialScroll()
    end
  end
end):start()

-- Code below will be executed only once on Hammerspoon (re)start
function isIdeFocused ()
  return string.find(hs.window.focusedWindow():application():title(), ideName)
end

if isIdeFocused() then
  if isPartialNavigationActive == true then
    enablePartialNavigation()
  end
  if isPartialNavigationWithScrollActive == true then
    enablePartialNavigationWithScroll()
  end
  if isPartialScrollActive == true then
    enablePartialScroll()
  end
end

A few differences with the plugin

1. (Bad) It will work only on Mac (both M-series and x86)
2. (Bad) It can set only PageUp / PageDown to navigate to a specific number of lines and it can not navigate by page percentage*
3. (Good) Keymap setup is optional
4. (Good) It will work not only in Editor but across all IDE views e.g. in files tree view
5. (Good) Even more nice features - see Extras section

*Because Hammerspoon is operating on the applications level, there is no way to get Editor's current number of lines. Though it's still possible to get the size of a window and adjust the pagination size, the results would be far from expected as soon as you would have a horizontal tab or a horizontal split

Basic setup

All the setup is at the top of the script:

• set the name of your IDE to ideName variable
• (optional) set the number of lines you would like PageUp / PageDown to move the caret to partialNavigateLines variables
• (optional) adjust the speed of the scrolling when PageUp / PageDown is pressed and hold with scrollSpeed

Extras

Partial navigation with scroll:

• go to Preferences -> Keymap and set some hotkey to "Move Up and Scroll", "Move Down and Scroll", "Move Up and Scroll with Selection", and "Move Down and Scroll with Selection"
• in the Setup block of the code, set isPartialNavigationWithScrollActive to true
• in the definitions of partialPageUpAndScroll, partialPageDownAndScroll, partialPageUpAndScrollWithSelection and partialPageDownAndScrollWithSelection change arguments to match the mapping so from would be the value you would like to press and to would be the hotkey you've set in Keymap
• if you would like to disable the default partial navigation without scroll, in the Setup block of the script set isPartialNavigationActive to false

Partial page scroll:

• go to Preferences -> Keymap and set some hotkey to "Scroll Up" and "Scroll Down"
• in the Setup block of the code, set isPartialScrollActive to true
• in the definitions of partialPageUpScroll and partialPageDownScroll change arguments to match the mapping so from would be the value you would like to press and to would be the hotkey you've set in Keymap

The list of available "key" values
The list of available "mod" values

What does the script do

• It remaps PageUp / PageDown / Shift + PageUp / Shift + PageDown to repeated Up / Down / Shift + Up / Shift + Down
• The remap would be enable/disable everytime the IDE would be focused/unfocused
• Applications other than the IDE would not be affected
• PageUp / PageDown hotkeys with modifiers other than Shift would not be affected (e.g. PageUp + Opt or PageDown + Shift + Ctrl would not be remapped)

[Vladivost]

Hey, thanks a lot for that, tried it, the script does in fact work!

[victor-falcon]

It's there any alternative for this plugin or plan to update it? I roll back from 2022.1 because this 😢

[Alexsey]

@victor-falcon are you using Windows/Linux or did the Hammerspoon workaround didn't work for you?

[victor-falcon]

@Alexsey I just tried it, and it works great. I never heard of Hammerspoon and I love it!

I updated the plugin source code to kotlin, changed some code, and is now working on EAP version again.

Attached plugin file. Later possibly with fork.

Unable to upload. Here: https://easyupload.io/fhigl2

Valid for 30 days.

[Vladivost]

Hey everyone, I've found another plugin that does roughly the same thing and works with the latest Intellij versions, maybe someone will find it helpful so I'm sharing it https://plugins.jetbrains.com/plugin/17449-jumper (I'm not affiliated with the creator)
