Variable and function name conflict in the tutorial

[henry2004y]

Hi,

When I tried to run the tutorial demos using Julia v1.11.5, I encountered the following error:

using GeometricIntegrators

function ẋ(v, t, x, params)
    v[1] = x[2]
    v[2] = sin(x[1])
end

tspan = (0.0, 10.0)
tstep = 0.1
x₀ = [acos(0.4), 0.0]

ode = ODEProblem(ẋ, tspan, tstep, x₀)

ERROR: cannot assign a value to imported variable GeometricIntegrators.tstep from module Main

An easy fix would be simply renaming tstep to Δt I guess?

Good catch. Your proposed solution would work. However, I rather tried to fix the root of the problem and renamed the tstep function to timestep which is more explicit and descriptive.

Unfortunately, now we have a little compatibility issue with some of the dependencies, which we will only be able to resolve next week. As far as I can see, everything seems to work, though.
