Changes not updating in a specific function

[yha]

Reproduced on two different machines with the following:

]dev Plots
In Juno:

using Revise
using Plots
pyplot()

pl = plot(rand(4));
Atom.displayinplotpane(pl)

Insert some printing into prepare_output at .julia/dev/Plots/src/plot.jl:253 and _before_layout_calcs(::Plot{PyPlotBackend}) at .julia/dev/Plots/src/backends/pyplot.jl:955 (both of these are called from Atom.displayinplotpane).
When rerunning, only the first change is reflected. The second one only prints after restarting Julia.

I think this is happening because of Plots' non-standard code loading for backends. You'll probably need to track those changes explicitly.

[yha]

Yes, it looks like backends/pyplot.jl is dynamically loaded (I had wrongly assumed only PyPlot and dependent modules would be).
But tracking explicitly doesn't seem to help here. The same issue is reproduced with the following code:

using Revise
using Plots
pyplot()

pl = plot(rand(4));
Revise.track(Plots, "$(dirname(pathof(Plots)))/backends/pyplot.jl")
Atom.displayinplotpane(pl)

Sorry for the long delay getting to this. I thought it was going to be very tricky, but with your manual track it turns out to have been a stupid relative-path issue with a one-line fix (and as usual a many-line test 😉). See #395 .

This will come out as Revise 2.3.1.

You may have seen it, but JuliaPlots/Plots.jl#2250 (comment) lists some options to get Revise to track such files automatically.
