Maybe this is a bug report. Please advise.
I have a small notebook that runs perfectly when I open it in Jupyter, but not at the REPL.
Working at a freshly-started Julia 1.2.0 REPL, when I say
```julia
using NBInclude
@nbinclude("CALO-MWE.ipynb")
```
I expect the minimalist workbook attached here to run successfully and print the computed result, but instead I get the error message below:
```julia
ERROR: LoadError: UndefVarError: slacksum not defined
Stacktrace:

```
I have Julia 1.2.0, with IJulia v1.20.0 and NBInclude v2.1.0.
What do you suggest?
Sorry, new here, don’t know how to attach the file named CALO-MWE.ipynb, so I’ll just paste it here:
```julia

{
"cell_type": "code",
"execution_count": 1,
"metadata": {},
"outputs": [],
"source": [
"slacks = [1,2];"
]
},
{
"cell_type": "code",

"metadata": {
"scrolled": false
},
"outputs": [
{
"name": "stdout",
"output_type": "stream",
"text": [
"\n",
"Total slack: 3.\n"
]
}
],
"source": [
"slacksum = 0;\n",
"\n",
"for sl in slacks\n",
" slacksum += sl\n",
"end\n",
"println(\"\\nTotal slack: $(slacksum).\")"
]
}
],

I think you might be running into a scope issue, although I’m not 100% sure how scoping works in notebooks run from the REPL.
My best guess: your code includes the loop
```julia
slacksum = 0
for sl in slacks
slacksum += sl
end
```
This works in the notebook because Notebooks by default use `SoftGlobalScope.jl`, however if you run the same code in the REPL, which doesn’t use `SoftGlobalScope` it raises an error because the loop creates its own scope, in which the variable `slacksum` is not defined. The solution is to annotate the line in the loop with `global`, to indicate that the loop is accessing a variable that’s defined in global scope.
The general solution to these things is not to run code in global scope, but to enclose everything in a function, although I see how this can be tricky in Notebooks with cell by cell execution.

There is a bit more info on the SoftGlobalScope here:

Yes. IJulia has a patch for the scoping issue. To apply for your example, go `@nbinclude(foo.ipynb, softscope=true)`

Thanks for the informative responses. The suggestion from @jlperla works for me, after changing the comma to a semicolon (and installing the SoftGlobalScope package):
```julia
@nbinclude(foo.ipynb; softscope=true)
```
