I am trying to run some code from the Meshes.jl test source code, and it fails. What am I missing?
using Meshes
points = P2[(0,0), (1,0), (0,1), (1,1), (0.5,0.5)]
#ERROR: UndefVarError: P2 not defined
#Stacktrace:
# [1] top-level scope
# @ REPL[2]:1
The code is from here: https://github.com/JuliaGeometry/Meshes.jl/blob/bcc08b0b53622f2578c61561fef91153c05c393b/test/mesh.jl#L176
If you look at the runtests.jl file (https://github.com/JuliaGeometry/Meshes.jl/blob/bcc08b0b53622f2578c61561fef91153c05c393b/test/runtests.jl#L118), P2 is defined as an alias for Point{2, Float64}.
T = Float64
P1, P2, P3 = Point{1,T}, Point{2,T}, Point{3,T}
If you run these two lines, your example code will work.
Alternatively, you can define your points as:
points = Point[(0,0), (1,0), (0,1), (1,1), (0.5,0.5)]
