## minimum reproducible steps

<!-- if possible, paste here a minimum reproducible example document and steps -->
Put the following code in 00.jl and run `weave("00.jl", cache=:off, out_path="output/")
`.
```julia
#' # Plot
x = rand(2, 10)
#' Create a histogram.
using Plots
plot(x[1,:])
#' Create a scatter plot
plot(x[1,:], x[2,:])

The weaving hangs at

julia> weave("00.jl", cache=:off, out_path="output/")
┌ Info: Weaving chunk 1 from line 2
└   progress = 0.0

Just found that things work in VSCode, but not in the repl nor emacs with vterm.

[Ossifragus]

If I start julia from a terminal, then it works. Maybe this is a problem for emacs julia-repl with vterm. I will test further.

[Ossifragus]

I do not fully understand the cause, but the problem is related to using X server with gksqt. Here is a workaround:

ENV["GKSwstype"]="nul"
weave("00.jl", cache=:off, out_path="output/")
ENV["GKSwstype"]="gksqt"

The first line ENV["GKSwstype"]="nul" activates the NULL device so that X server will not be requested. After this, weave("00.jl", cache=:off, out_path="output/") works as expected. The third line ENV["GKSwstype"]="gksqt" activates gksqt in case some plots need to be displayed.

ENV["GKSwstype"]="nul"

I can report this walk-around does work.

I just got hit by this bug too, when I tried to run Weave from my terminal. The fix worked though.

[newptcai]

It seems that there had not been any bug-fixing for quite a while. I wonder if the project has been abandoned? Can we make some donations so as to motivate the maintainer to fix some bugs?

[00krishna]

@newptcai I am pretty sure that the project is still maintained. I mean so many people use Weave for everything. It might just be that a lot of the code is pretty stable? That is what I am hoping. I still use Weave for so many things, not sure what would replace it.

Thanks, this helped me when my plots were hanging!
