Is that possible to keep the rendering in insert mode?
The rendering is very cool and good. But everytime when I edit the file, the insert mode will change the height of each lines. It feels very werid.
If it's possible to keep the rendering or at least keep the height of each line, it will be much better.
Thanks a lot.

Yes, the set of modes this plugin does rendering in is configurable via the render_modes option.

By default it is set to:

require('render-markdown').setup({
    render_modes = { 'n', 'c', 't' },
})

You can add insert mode specifically to it with:

require('render-markdown').setup({
    render_modes = { 'n', 'c', 't', 'i' },
})

Or you can have it render in all modes (insert, visual, operator pending, etc.) by setting the value to true:

require('render-markdown').setup({
    render_modes = true,
})

But everytime when I edit the file, the insert mode will change the height of each lines. It feels very werid.

I'm not sure what you mean by this, this plugin does not change the height of lines. I don't think that's actually possible to do.

I assume you mean something different than how tall each line is, can you give me a specific example, either with a screenshot or some markdown where the lines are different heights in different modes.

Thank you very much for your help. render_modes is the solution. Sorry that I didn't find this config option before.

And about the height of each lines confusion, sorry that I am not a native English speaker. Basically, the headings with virtual borders and tables will change how tall each line is. Enabling rendering in insert mode makes me feel more comfortable otherwise the position of the cursor in the monitor will change btw normal and insert modes. You can see the screenshot in the end if my English is not clear.

I am very happy with the rendering in insert mode and I think it should be the default.
Very powerful tool. Thanks.

Dear @MeanderingProgrammer, Is that possible to change render_modes temporarily for the current buffer? I tried :lua require('render-markdown').setup({render_modes = { 'n', 'c', 't'}}), it overwrites all the settings instead of just changing render_modes. Thanks a lot.

[MeanderingProgrammer]

Ah, I see. There's not really a good way to keep just the virtual lines around used for heading and table borders.

Instead the best you could do is disable borders for both, i.e.:

require('render-markdown').setup({
    heading = { border = false },
    pipe_table = { style = 'normal' },
})

If you want to keep them the only alternative is to enable rendering in more modes like you have done.

Is that possible to change render_modes temporarily for the current buffer?

No this is not possible but you can toggle whether the current buffer is rendered or not with :RenderMarkdown toggle.

Thanks a lot for the reply. I have created an user defined command to handle this. Use a global variable for opts. Simply change opts.render_modes and setup again. It works well. :)

@MeanderingProgrammer I've found that if I enable rendering in all modes with render_modes=true, then in insert mode the screen jumps around on each keystroke because the left margin seems to momentarily shrink a bit on each keystroke.

Do you have any idea why that might be? I'm using the default left margin configuration in LazyVim on Kitty.

Like the OP I'm fundamentally trying to stop the text on the page shifting as I go in and out of insert mode caused by the rendering turning on and off. I think rendering in all modes might be the right solution except for this weird margin thing making it not really usable.
