Print ocp

[jbcaillau]

@ocots for the record (there might no be a block)

julia> @def o t ∈ [ t0, t0 + 4 ], time
Error showing value of type OptimalControlModel{Autonomous, Fixed}:
ERROR: AssertionError: ocp.model_expression.head == :block
Stacktrace:

[ocots]

This part must be udpated:

CTBase.jl/src/print.jl

Line 18 in 8f661a2

if !isnothing(ocp.model_expression)

Can you give the dump of o.model_expression?

julia> t0 = 0

Fixed.

@ocots thanks. I see that it has been merged in develop, not main ✅

[ocots]

Yes and then develop into main. I have removed develop since it is not useful anymore. We can add it if we have a big update to make.
