How to make font size smaller for inline math and decrease left and right margins?

Thank you contributors for this plugin!

How to make it more aligned with the text by decreasing the font size and margins? See picture

I was having the same issue. A fix would be very much appreciated.

This plugin is amazing, thanks!

Sadly there's no option for this right now :(

I am kinda busy right now so I am not working in this plugin, but I pretend to work on it in the following weeks.
But do you have any suggestion on how you want this to be fixed? I can set a limit to the size to prevent inline equations being so big, but some equations won't fit and will have to be made smaller, since I can't create virtual space for inline equations

@Thiago4532 I guess, it would be great to have first the margins on both sides reduced for an inline formula. Thanks for the plugin, I agree that's amazing!

So in playing around, it looks like the issue is that 99% of the time, the rendered latex expression is smaller than the code that generates it (i.e. \forall n \in \mathbb{Z} renders as ∀ n ∈ ℤ which is 24 chars vs 7). Considering the latex rendering is meant to be at the same font size as the rest of your text, this causes sizing issues.

The plugin handles this by center justifying the render in the png it makes and puts the extmark containing the image over the width of the latex, which is a brilliant solution, @Thiago4532, but has the side effect of handling it that way is the large margins that we see:

side note: wrapping it totally broken but that is a much later problem

I'm no neovim, lua, or JS, expert, but my suggestion for this would be to use -trim when converting to png with Magick and take out the -gravity option which would give an image that's exactly the size of the equation. Then (and bear with me on this one):

1. Rewrite the processing of inline rendering to make it so that any line containing a latex expression is concealed
2. Make an array of strings of non-latex sub-strings in the line
3. Figure out how many columns (and use ceiling when rounding) each individual extmark render takes up
4. Piece together a string which combines the sub-strings with appropriate amounts of spaces to accommodate for where the extmark renders will go (we can thank monospace fonts for this)
5. Set the string as the conceal text for that line
6. Create the individual extmarks where appropriate

Happy to clarify anything if needed! Hopefully this is a good and feasible way of going about it 😄

Hello! Sorry for taking so long to answer you. That's exactly the solution I'm planning, but I am really busy right now since I started an internship. But I hope to start fixing the issues in early April.

I am also taking a look if it's possible to write a "solution" for neovim/neovim#14409, since concealing and wrapping don't work nice together.

Hi! No worries -- best of luck with the internship and please keep us appraised if you run into any issues or roadblocks 😄

[Thiago4532]

Hi! I finally got some time, I hope to release some updates for this plugin this week, this feature is my highest priority.

Hi were you able to do any work on this feature? Happy to take a look at any issues if they exist
