using packages other than Plots.jl may induce an error about pandoc-plot HOT 6 CLOSED

Hello,

I'm no expert on Julia. Would you be able to answer the following questions:

• What error are you getting? Can you copy-paste the error?
• What version of pandoc / pandoc-plot are you using?
• Can you write down a simple exampel that reproduces the error, so I can test it here?

Thanks!

from pandoc-plot.

pandoc.exe 2.11.3.1 and pandoc-plot 1.0.0.0 (Win10 OS)

Minimum working example looks like,

using CSV, Plots # CSV package must be loaded here to read a csv file
mtx=CSV.read("foo.csv", header = false); mtx=Matrix(mtx)
plot(mtx[1:end,1], mtx[1:end,2])

assuming the content of foo.csv file below;

1,3
2,5
3,4

This complains some error that will be posted later.

from pandoc-plot.

The error looks like: (unless loading CSV package, this did not occur)

ERROR | Running command
ERROR |     julia.exe "C:\Users\JohnDoe\AppData\Local\Temp\pandocplot1257825860.jl"

First, notice that the second issue says: Julia/Plots.jl toolkit not installed.. This probably means that the Plots package is not installed.

I think the first issue is that this is not valid Julia, and the error is not being reported by pandoc-plot correctly. If I try the code above with CSV 0.8.2:

julia> mtx=CSV.read("test.csv", header=false); mtx=Matrix(mtx)
ERROR: ArgumentError: provide a valid sink argument, like `using DataFrames; CSV.read(source, DataFrame)`

The following Markdown file works with pandoc-plot:

# Test

```{.plotsjl}
using CSV, Plots, DataFrames
mtx=CSV.File("foo.csv", header = false) |> DataFrame
plot(mtx[1:end,1], mtx[1:end,2])
```

Can you confirm to me that the Julia code works in the Julia REPL? Maybe you are using an old version of CSV?

from pandoc-plot.

Thanks! I realized that the reason of failure comes from multi-statements using semicolon;

mtx=CSV.read("test.csv", header=false); mtx=Matrix(mtx)

By separating this into two lines,

mtx=CSV.read("test.csv", header=false)
mtx=Matrix(mtx)

this now works.

The problem does not come from loading multiple packages in addition to Plots.jl which was my misunderstanding.

Great, so I will close this issue.
