LaTeX Features (exporting, syntax highlighting, preview) about orgmode

[kristijanhusak]

Thanks for the detailed explanation.

To be honest, I have absolutely no experience with Latex. Any assistance on this topic is appreciated.

Is Latex in org only available between /begin{something} /end{something} or also outside of it?

Image preview is possible via https://pypi.org/project/ueberzug/ (only on X11), but I'm not even sure how would it be done.

For the publishing, I plan to support all publishing by using the emacs orgmode tools. I know https://github.com/jceb/vim-orgmode supports it so I assume it's possible.

From what I see, fastest thing that could be done is to allow "tex" highlight as part of org. Publishing will come later, and i'm not sure about the previews.

Sure, let me know if you need anything else. I have minimal experience making lua plugins but I can try my best.

According to the org wiki, latex fragments are identified as any of the following

1. Anything encased within \begin and \end
2. Anything within the LaTeX math delimiters (this is either $text$ (no whitespaces allowed), $$ text $$, \( text \), or \[ text \]

(a more detailed explanation can be found here: https://orgmode.org/manual/LaTeX-fragments.html#LaTeX-fragments)

Looks good! I think the only possible way is to create a floating window, start a terminal, and use ueberzug to display the image. I use this method to display images for my startup dashboard. The only issue is that you would have to keep the preview aligned with scrolling text, and regenerate the preview multiple times (causing lag and performance drops)

For the publishing, I plan to support all publishing by using the emacs orgmode tools. I know https://github.com/jceb/vim-orgmode supports it so I assume it's possible.

I believe the code we need is Here. Its in python so we would need to translate that to lua, but the logic looks quite simple.

[kristijanhusak]

I think, for now, I could add latex highlighting for those fragments (via syntax region), and have publishing be done separately for everything.

For the image preview, do you know if there's a way to generate the image with emacs?

[shaunsingh]

You can use org-latex-preview to generate a preview of the latex equation under the cursor. I'm not sure once you generate a preview, how to extract it.

[kristijanhusak]

@shaunsingh I added some basic highlighting options. It's disabled by default. Check here https://github.com/kristijanhusak/orgmode.nvim/blob/master/DOCS.md#org_highlight_latex_and_related.

Let me know how it works for you.

[shaunsingh]

Seems like it isn't working on my end. I tried both the "native" and "entities" options.

This is my config with packer:

        use {
            'kristijanhusak/orgmode.nvim',
            ft = {'org'},
            config = function()
                require("orgmode").setup(
                    {
                        org_highlight_latex_and_related = 'entities'
                    }
                )
            end
        }

[kristijanhusak]

Please pull latest master and give it another try.
If it doesn't work, please try without packer's lazy loading.

[kristijanhusak]

I added exporting. See https://github.com/kristijanhusak/orgmode.nvim/blob/master/DOCS.md#org_export.

[shaunsingh]

Please pull latest master and give it another try.

Thanks, works well now.

I added exporting.

Works as expected. Would you consider also adding pandoc as an export option? Might be useful for those who don't have emacs installed but would like to export to pdf.

[kristijanhusak]

Yeah, why not. I'll probably group exports to allow more options, and also expose a setting for custom exports.

[kristijanhusak]

I added pandoc exports for several file types (html, tex, pdf). Also, I added an option to add custom exports. See https://github.com/kristijanhusak/orgmode.nvim/blob/master/DOCS.md#org_custom_exports . Let me know how it works.

Regarding the preview, I'm not sure if I'll be adding it. It seems very complicated, especially since Neovim can't show images inline.

I didn't try, but you could maybe use this solution via lsp, and here's the preview.

[shaunsingh]

Is it possible by any chance to use treesitter for the latex highlighting? The treesitter colors are a little easier to read:

(treesitter on the right)

[kristijanhusak]

I don't think it's possible to inject treesitter for some syntax. Once we have treesitter support in the whole org, we should be able to do this easily.

[kristijanhusak]

@shaunsingh did you had a chance to test features added through this issue? Can this be closed if everything is working as expected?

[shaunsingh]

Everything works great! The only thing I couldn't get working was the preview with lsp, since the built-in markdown renderer in my gui didn't seem to support mathjax, but that isn't something you can solve

You can close the issue

[kristijanhusak]

Awesome, thanks for the feedback and for testing it.
