Hello,

I would like to get the filepath for the current Pluto notebook.  
Is there a way to get this information?

Thanks

Michel

PS:  
My purpose is to write a SaveAsIpynb function that would keep a Jupyter notebook copy of the current Pluto notebook.

You can get the folder that the notebook is in with `@ __DIR__ ()`, and you can get files in that directory with `readdir`, but I don’t know how to get the name of the notebook directly.

You can use the `@ __FILE__ ` macro and remove the trailing characters after the `#==#<...>`. By doing something like:

```julia
notebookpath() = replace(@ __FILE__ , r"#==#.*" => "")

```

Thanks both!  
I also found pathof and splitdir to help.  
It is not yet clear how I will do it.  
I’ll come back if I am stuck!

Just tested.  
In a Jupyter notebook, @ **FILE** returns “In[12]” , the cell in the notebook.

In Pluto it rerturn something like:  
“C:\Users\myPC\Pluto notebooks\myPackage\examples\Pluto\example.jl#==#06f9b601-36bf-440d-812f-a858b101fb2a”

So, for Pluto this would be enough, but not for Jupyter!  
I hope there is a way to have that working for both Jupyet and Pluto.  
I want to have this code inside the package.

Thanks

Michel

This is an old unsolved [issue](https://github.com/ipython/ipython/issues/10123) for jupyter notebooks.

Hello Pangoraw

I just realised that @ **FILE** returns the path of the file where the macro is used.  
Actually, I need the path of the notebook (Pluto), but the macro will be in a package used by the notebook.  
Is there a way to find the path of the topmost “caller”, in a sense ?

Thanks

Michel

I think the only way you could have knowledge about the caller scope is by using a macro.

Quoting the [Julia documentation](https://docs.julialang.org/en/v1/manual/metaprogramming/#Macro-invocation):

> In addition to the given argument list, every macro is passed extra arguments named ` __source__ ` and ` __module__ ` .
> 
> The argument ` __source__ ` provides information (in the form of a `LineNumberNode` object) about the parser location of the `@` sign from the macro invocation. This allows macros to include better error diagnostic information, and is commonly used by logging, string-parser macros, and docs, for example, as well as to implement the [`@ __LINE__ `](https://docs.julialang.org/en/v1/base/base/#Base.@ __LINE__ ), [`@ __FILE__ `](https://docs.julialang.org/en/v1/base/base/#Base.@ __FILE__ ), and [`@ __DIR__ `](https://docs.julialang.org/en/v1/base/base/#Base.@ __DIR__ ) macros.
> 
> The location information can be accessed by referencing ` __source__.line` and ` __source__.file`

So you could do something like this:

```julia
macro export_to_jupyter(...)
  notebook_name = __source__.file
  return quote
    ... # code using $notebook_name
  end
end

```

Thanks Pangoraw!

A one liner to wrap my function and that’s is, thanks to you:

```julia
macro toJupiter()
    toJupiter(String(split(String( __source__.file),"#==#")[1]))
end

```

Now I can convert a Pluto nb to Jupyter without thinking.

From Jupyter to Pluto it will not work, because I do not get the path, I get the cell instead.  
But that’s less important for me.

Thanks

Michel

that does not seem to be the case anymore. how can i get the `pwd` from which I started the julia session that called `Pluto.run()`?

It’s not this directory:

 ![Screenshot 2021-12-22 at 11.59.05](https://global.discourse-cdn.com/julialang/original/3X/8/5/85b2b178a034bf9dee0598c77ec34463e139692f.png)

I tried something like this

```julia
julia> Pluto.Configuration.Options(server=Pluto.Configuration.ServerOptions(root_url = pwd()))
Pluto.Configuration.Options(Pluto.Configuration.ServerOptions("/Users/florian.oswald/.julia/pluto_notebooks", "127.0.0.1", nothing, true, false, true, "/Users/florian.oswald/git/ClimateNotebooks/notebooks/", false, false, 0.4, false, nothing, false, 0.0), Pluto.Configuration.SecurityOptions(true, true), Pluto.Configuration.EvaluationOptions(true, true, false), Pluto.Configuration.CompilerOptions(nothing, nothing, nothing, nothing, nothing, "no", "no", 2))

julia> Pluto.run(Pluto.Configuration.Options(server=Pluto.Configuration.ServerOptions(root_url = pwd())))
ERROR: AssertionError: endswith(session.options.server.root_url, "/")

```

This discussion is about getting the file path to the actual notebook file. Since each notebook runs in a different Julia process, they each get their own `pwd()`. You can use an environment variable to get the working directory of the Pluto process:

```julia-repl
julia> withenv("PLUTO_ROOT_DIR" => pwd()) do
           Pluto.run() # launch Pluto with PLUTO_ROOT_DIR in the env
       end

```

and then in the notebook you can get it with `ENV["PLUTO_ROOT_DIR"]`. Also note that `root_url` refers to the url of the Pluto webserver and is not related to the directory in which the draft notebooks are created.

Great thanks! That’s what I need. I could not make this work with the advised solution of using `Base.current_project()` because it would always look for a project at `~`. When trying to use a local project file that is shared with a local package.
