Plugin: Keep Cursor Synced between editor and md viewer

ylc395 · 2021-10-11T11:34:11.125Z

Oh, I just got we you mean. View-Only Mode -> db click -> Editor-Only Mode, right? I will add a option in 1.2.0

Daeraxa · 2021-10-11T11:35:42.013Z

To be honest either works perfectly fine for me but yes, that is what I originally meant. Thanks so much for implementing it.
(I was in the middle of saying I couldn't see a 1.0.2 update yet but I've just spotted the NPM package go up to 1.1.0) so hopefully the repo will update in 25 mins and I can have a play.

Hi @ylc395

Thank you for this initiative. For me, the Double click will toggle editor out when in View Mode option does not work. It's like an infinite loop where the plugin tries to activate/deactivate the "view" mode. I should mention that in the general settings of Joplin I only alternate between the editor and the viewer.

ylc395 · 2021-10-11T13:27:58.802Z

Bug confirmed. Fixed in 1.2.1. Waiting for NPM to update, may take hours.

Daeraxa · 2021-10-12T11:27:51.819Z

Just downloaded 1.2.2 and it is working nicely with the toggle out to editor function, thank you for adding it.
One thing I have noticed is that it doesn't seem to like code blocks in various forms:

Inline code blocks on double click seems to make the cursor jump to the previous section even when after normal text
Fenced code blocks don't seem to work at all

On the other hand, indented code blocks work just fine

I don't quite get this, can you provide a gif or something?

Fenced code blocks don't seem to work at all

Yes, I don't have a good idea to handle Fenced code for some reasons. If anyone can help, PRs are welcome

It's a bit odd. You can see in the gif that sometimes things don't quite line up right. Sometimes I can double click the inline code and the cursor goes to the right place but the highlight doesnt. Other times it goes to the wrong line entirely but if you double click again without moving anything else it will change the cursor position. Hope the gif is clear enough.

Do you know why my Joplin MD viewer is not like yours when handling line-break?

Nacandev · 2021-10-14T03:51:58.025Z

I like this plugin! It would be better if it will show a mark on the scrollbar (just like the search mark which appear on the scrollbar when searching a word with ctrl+f). Or, add a method that can directly jump to the exact location on the render viewer.

Besides, I saw you have a question about the line-break. That is about the setting on preference > markdown:

Daeraxa · 2021-10-14T08:13:42.629Z

As @Nacandev mentions, I don't have soft breaks turned on.

Its worth noting that there is a merged PR that I don't think is in a full release yet (but you can test if you build Joplin yourself) that synchronises the scrolling better so that this shouldn't be necessary

so why are there diffences between your rendered markdown and mine?

Daeraxa · 2021-10-14T08:24:49.090Z

If I turn them on then it does look like yours.

I stand corrected, it hasn't been merged but you can still build it from the other branch:

This PR provides the synchronous scroll capability between Markdown Editor and V…iewer. It's based on [CalebJohn's branch](https://github.com/CalebJohn/joplin/tree/sync-scroll), and the following features are added. - Bi-directional sync-scroll (viewer <-> editor) - Performance improvements: - The mapping between line and scroll position is cached. - Efficiently observing rendering updates to keep scroll consistency - Some cleanups Related forum topics and github issue: - [[Feature request] Better synchronized scrolling in desktop app](https://discourse.joplinapp.org/t/feature-request-better-synchronized-scrolling-in-desktop-app/3609) - [Syncing Split View (Markdown/Preview)](https://discourse.joplinapp.org/t/syncing-split-view-markdown-preview/12131) - [When scrolling, the two sides are out of sync · Issue #2242 · laurent22/joplin](https://github.com/laurent22/joplin/issues/2242) NOTE: If you use an HD display or use zoom in/out, applying the following PR is highly recommended with this PR. - [Desktop: Resolves #4827: Laggy Scrolling in Viewer by ken1kob · Pull Request #5496 · laurent22/joplin](https://github.com/laurent22/joplin/pull/5496)

I'm not sure I understand the argument about it being "too fast". The speed depends on which pane you are scrolling.

Nacandev · 2021-10-14T09:30:01.704Z

Oh! Sorry, I made a logic mistake. You are right, that's what I need, I'm just thinking too much.

splerman · 2021-10-15T19:36:05.003Z

I was surprised by how dramatic the usability of Joplin is improved by this plugin. Maybe it's just my workflow/workstyle, but this is awesome! Thank you!

Is there any way to make the highlighting more legible in dark themes?

I regularly switch between light and dark themes so I need visibility in both conditions. I tried using a darker color for the highlighting which worked, but when I switched to a light theme the text became less legible there.

Edit: I'm also noticing reliability issues with the plugin itself at times.

It doesn't always highlight the selected section correctly:

Double clicking also doesn't jump to the correct section a lot of the times.

Haven't been able to identify the cause though and restarting Joplin seems to fix it.

ylc395 · 2021-11-16T11:04:06.875Z

I will try to fix this in next realease. And add a configuration to dark mode

ylc395 · 2021-11-18T10:55:00.606Z

@shbach Hi, I just update this plugin to 2.0.1. It's a totally rewrite so there would be no more bug like incorrect highlight.

As for dark mode, I add an extra class name for highlighted line so you can set its appearence by userstyle.css. Check the doc for details.

ylc395 · 2021-11-18T11:06:52.021Z

select

And thanks to this rewrite, some advanced feature are possible, such as sync selection. But that would be a little complicated, so it will take time

shbach · 2021-11-19T04:23:01.145Z

Looks good, thanks so much!
