Question

Rendering LateX markdown in textbox by delimiting with $ fails, only works with $$

Describe the bug

Latex code delimited by a single $ is left unaltered after rendering in textbox. Instead, when flanked by $$, it is rendered correctly, i.e. on a line of its own. I assume this to be a bug, because I found references in previous discussions to delimiting LateX by $, and common markdown engines, such as RStudio, accept both: $ for inline rendering, and $$ for a line of its own.

The consequence of having to flank all LateX by $$ is that every LateX expression is rendered on a new line of its own. For example, "The letter $$y$$ is often used for the dependent variable" is rendered

The letter
y
is often used for the dependent variable

        "The letter $$y$$ is often used to represent the dependent variable", 
        "The letter $y$ is often used to represent the dependent variable"])

app = gr.ChatInterface(fn=random_response, type = "messages", title = "Linear Models")
app.launch()

Hi @roberto-viviani you can change the default latex delimiters by setting the latex_delimiters attribute of gr.Chatbot and passing it in the chatbot parameter of gr.ChatInterface. See:
