I’m trying to create a function that calls another function.

```julia
using Weave

function knytte( file_name, doc_type )
    weave( file_name, doctype = doc_type )
end

knytte( "test.jmd", "md2html" )

```

The content of “test.jmd” could be anything.

Somehow julia just kept executing the weave() function over and over.

Does someone have an idea how the code needs to be changed?

Thanks!

I just tried running exactly your code with `test.jmd` containing just:

```nohighlight
#hello world

```

and it ran correctly. I also don’t see anything obviously wrong with the code you’ve written.

Can you post the simplest possible `test.jmd` that reproduces the issue for you?

Thank you!

I made a mistake in the julia markdown file. I was calling the knytte() function to the julia markdown file, in the julia markdown file. This created the infinite loop!
