Fix 178 precompilation makie

[BambOoxX]

Attemp at fixing precompilation issues due to Makie usage. See #178

Wow!!!

Thank you a lot for your work. I am testing it and so far it works well. The only thing is the following.

This seems to error

using Revise, GLMakie, LinearAlgebra, BifurcationKit
k = 2
N = 1
F(x, p) = @. p * x + x^(k+1)/(k+1) + 0.01
Jac_m(x, p) = diagm(0 => p .+ x.^k)

# bifurcation problem
prob = BifurcationProblem(F, [0.], 0.5, (@optic _), J = Jac_m)

# continuation options
opts = BK.ContinuationPar(ds=0.001, max_steps = 140, newton_options = NewtonPar(tol = 1e-8))

# algorithm
alg = DefCont(deflation_operator = DeflationOperator(2, .001, [[0.]]), perturb_solution = (x,p,id) -> (x  .+ 0.1 .* rand(length(x))))

brdc = continuation(prob, alg,
	ContinuationPar(opts, ds = -0.001, max_steps = 800, newton_options = NewtonPar(verbose = false, max_iterations = 6), plot_every_step = 40),
	;
	plot=true,
	callback_newton = BK.cbMaxNorm(1e3) # reject newton step if residual too large
	)

because

ERROR: MethodError: no method matching plot_DCont_branch(::BifurcationKit.BK_NoPlot, ::Vector{ContResult{…}}, ::Int64, ::Int64, ::Int64)

Closest candidates are:

I think I met the same problem, did you try with BifurcationKit.plot_DCont_branch, maybe these are just not properly exported as is.

[rveltz]

There is one major issue with this interface: you never have BifurcationKit._plot_backend equal to BK_Makie().

[BambOoxX]

Ah yes, my bad, it's a typo, I targeted :MakieExt but you named it :GLMakieExt. I'll fix that right now.
Then, to load get get_plot_backend()==BK_Makie() you just need to do using GLMakie, BifurcationKit

[rveltz]

I corrected the change in a previous commit.

As get_plot_backend is not called after loading GLMakie, the const _plot_backend is not updated

[BambOoxX]

I solved that in the last commit by triggering an update with __init__s in each plotting extension. Based on the discussion in JuliaLang/julia#13817.

Great work! Thank you.
