wrongly parsed equation about nabla.nvim

[max397574]

just had the same with a fraction

Could you try to pull the latest and see if the issue still persists? The equation looks fine for me.
Otherwise what delimiters do you use?

[max397574]

it still doesn't work
it happens with $xxx$, $$xxx$$ and \[xxx\]

Could be another plugin interferring, I just ran it the test case on the Github CI and the equation is displayed correctly.

The following code should give the formula in an array:

local parser = require("nabla.latex")
local exp = parser.parse_all([[y_{unten}=-\sqrt{r^2-x^2}]])
local ascii = require("nabla.ascii")
local g = ascii.to_ascii({exp}, 1)
local drawing = vim.split(tostring(g), "\n") -- table of lines with the formula in ASCII form

If the array of lines is correct, the issue is when displaying into a popup.

Have you got a clue on what was wrong? I cannot reproduce this so it's difficult for me to do anything.

[max397574]

the output from the above code snippet is correct
but what's displayed in the window is wrong

[jbyuki]

Something must be happening to the buffer, like a auto-formatter kicking in. nabla.nvim only takes those lines and put them in a float buffer using vim.lsp.util.open_floating_preview. I'll close this for now because I don't think it's related to nabla.nvim directly.

it seems like noice.nvim causes issues
not sure if I should open an issue here or there

[max397574]

you have to pass stylize_markdown=false as an option to vim.lsp.util.open_floating_preview

[max397574]

that fixes this issue and also improves highlighting I just realized xD

Thanks for the debug, I haven't installed noice so that's why I didn't see it but probably a lot have. I'll do that one change you mention.
