To avoid the horizontal scrolling necessary to read a very long unsplit string, any suggestions on how to split the following very long string used in a macro?
# mwestr.jl : very long string used by a macro
using GLMakie
using Printf
function mwestr()
# initialize figure
fig = Figure(resolution = (500, 500))
ax2d = Axis(fig[1,1],
limits = (-1,1, -1,1),
xlabel = "x (cm)",
ylabel = "y (cm)")
# plot initial observable data
zCut::Float32 = 1f0
strHeight = @sprintf(
"slice height = %.2f cm\nslice height = %.2f cm\nslice height = %.2f cm\nslice height = %.2f cm",
zCut, zCut, zCut, zCut)
# str1 = "slice height = %.2f cm\n"
# str2 = "slice height = %.2f cm\n"
# str3 = "slice height = %.2f cm\n"
# str4 = "slice height = %.2f cm"
# strHeight = @sprintf(string(str1, str2, str3, str4),
# zCut, zCut, zCut, zCut)
# strHeight = @sprintf("$str1$str2$str3$str4",
# zCut, zCut, zCut, zCut)
str_obs = Observable(strHeight)
text!(ax2d, str_obs,
position = (0.05, 0.60),
space = :data)
fig
# generate 2D video
# zMax = 2.0
# nFrame = 100
# record(fig, "mwestr.mp4", 1:nFrame) do iFrame
# zCut = zMax - abs(zMax - 2*zMax*(iFrame-1)/nFrame)
# str_obs[] = @sprintf(
# "slice height = %.2f cm\nslice height = %.2f cm\nslice height = %.2f cm\nslice height = %.2f cm",
# zCut, zCut, zCut, zCut)
# end # for each video frame
end
My attempts to split the string all resulted in the following error message:
ERROR: LoadError: MethodError: no method matching Printf.Format(::Expr)
