Question 1

How do I set up mdeval.nvim to evaluate Python code blocks?

Accepted Answer

After installation, add 'python' to vim.g.markdown_fenced_languages and optionally configure eval_options in setup. By default, it uses the standard Python interpreter, but you can customize commands as needed.

Question 2

Is mdeval.nvim better than Sniprun for code evaluation in Neovim?

Accepted Answer

mdeval.nvim focuses on simplicity and safety for document-based evaluation with confirmation prompts, while Sniprun offers more features like real-time output. Choose mdeval for straightforward use, Sniprun for advanced capabilities.

Question 3

Can mdeval.nvim handle errors in code blocks, like syntax issues?

Accepted Answer

Yes, it captures the full output of code execution, including error messages from compilers or interpreters, and inserts them after the code block, so you can debug directly in your document.

Question 4

How do I disable the confirmation prompt for specific languages like Rust?

Accepted Answer

Use the allowed_file_types option in the setup function, e.g., setting it to {'rust', 'haskell'} allows those languages to execute without confirmation, while others still prompt.

Question 5

Does mdeval.nvim work with compiled languages like C++ or Java?

Accepted Answer

Yes, but you need to configure the command and options in eval_options. For C++, set the command to clang++ with flags; for Java, specify javac and java commands for compilation and execution.

Question 6

What happens if I run mdeval.nvim on a large code block with intensive computation?

Accepted Answer

It executes the code using the configured command, which may block Neovim temporarily. There's no built-in timeout or async handling, so ensure your system can handle the execution without freezing.
