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 :(

[Vladivost]

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

```lua -- 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.

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](https://www.hammerspoon.org/docs/hs.keycodes.html#map) [The list of available "mod" values](https://www.hammerspoon.org/docs/hs.hotkey.html#assignable)

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.

Here is a slighlty updated version with more options:

[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)

[momomo]

[momomo]

Here is the alternative release based on this one instead:

https://github.com/momomo/mmm.intellij.plugin.Partial/tree/master/releases

Just download the zip file and install.

[FeralFox]

Here is the alternative release based on this one instead:

https://github.com/momomo/mmm.intellij.plugin.Partial/tree/master/releases

Just download the zip file and install.

Thank you! Works like a charm. Hope the PR of @canelhasmateus will be approved soon. https://github.com/andreycizov/idea-partialnav/pull/13

[momomo]

Breaks in latest EAP. Need a new release.

[momomo]

Spent another hour to make another build:

si.mmm.intellij.plugin.Partial-1002.42.zip

[ryletko]

for 2022.3 https://github.com/ryletko/mmm.intellij.plugin.Partial/releases/tag/Release

[FeralFox]

I have published a working version of this plugin which can be used as an alternative. It is called Partial Page Scrolling. Basically I didn't want to always download the fixed version and apply it manually in all of the IDE's I work with. It is based on this repo and does also work when the IDE is indexing. I made some adjustments, most important to mention is that the dropdown for relative scrolling height adaption has been replaced with a normal text entry. So the user can define any percentage he/she wants instead of choosing from a predefined list. The plugin is here https://plugins.jetbrains.com/plugin/23332-partial-page-scrolling

@andreycizov I hope this is fine and the contributions are sufficient. If not, please contact me. Thank you very much for your effort when creating this plugin: 🍻

Merry Christmas
