A note about the CHANGELOG

Hello 👋 and thank you for contributing to Gradio!

All pull requests must update the change log located in CHANGELOG.md, unless the pull request is labeled with the "no-changelog-update" label.

Please add a brief summary of the change to the Upcoming Release > Full Changelog section of the CHANGELOG.md file and include
a link to the PR (formatted in markdown) and a link to your github profile (if you like). For example, "* Added a cool new feature by [@myusername](link-to-your-github-profile) in [PR 11111](https://github.com/gradio-app/gradio/pull/11111)".

If you would like to elaborate on your change further, feel free to include a longer explanation in the other sections.
If you would like an image/gif/video showcasing your feature, it may be best to edit the CHANGELOG file using the
GitHub web UI since that lets you upload files directly via drag-and-drop.

@abidlabs lmk if you think adding both params is unnecessary. Maybe we could use passing None into latex_delimiters as a way to turn off latex rendering.

All the demos for this PR have been deployed at https://huggingface.co/spaces/gradio-pr-deploys/pr-4516-all-demos

[abidlabs]

Nice! Yeah, I think both is unnecessary. You could just pass in an empty list to latex_delimiters to indicate no LaTeX should be rendered. (We should add this to the docstring for latex_delimiters)

Also, we should mark this as a breaking change in the changelog as now by default we are only rendering LaTeX if enclosed with double $ signs.

[abidlabs]

Some suggestions on the docs above. But tested and it works well @dawoodkhan82!

[dawoodkhan82]

Display false:

Display True:

Basically inline or not

You could just pass in an empty list to latex_delimiters to indicate no LaTeX should be rendered. (We should add this to the docstring for latex_delimiters)

Should it also accept None so either empty list or None can disable latex.

[abidlabs]

Should it also accept None so either empty list or None can disable latex.

Sure, sg

[abidlabs]

@dawoodkhan82 this looks good. However, it's strongly recommended not to use lists (or other mutables) as argument defaults.

So I'm going to change this to set the default value of latex_delimiters to None, which internally will be set to [{"display": True, "left": "$$", "right": "$$"}]. This means that we'll have to reverse this change:

Should it also accept None so either empty list or None can disable latex.

So now if you want to disable LaTeX altogether, you need to pass in an empty list

Few nits, but lgtm!

[pngwn]

Since this is always set in the backend I don't think we need this default.

[pngwn]

Ditto for here.

Tested the latest version with:

import gradio as gr

latex = """
I want to eat $3.4 worth of bananas and $2 worth of apples. The equation for the sum is $$3.4+2=5.4$$ thanks!
"""

message = [(
    "write a python program",
    latex
), (
    "write a python program",
    latex
)]

with gr.Blocks() as demo:
    gr.Chatbot(
        message
    )
    
demo.launch()

And looks good to me @pngwn!

Awesome, thanks @abidlabs!
