1 week ago This seems to actually be a Symbolics.jl bug. These work:
using ModelingToolkit
t = ModelingToolkit.t_nounits
@variables u(t)=1 [input = true, disturbance = true]
@variables begin
u(t) = 1
end
@parameters begin
a = 1
end
@parameters begin
a = 1, [input = true, description = "true"]
endbut this errors
julia> @variables begin
u(t) = 1, [input = true]
end
ERROR: syntax: misplaced assignment statement in "[input = true]" around REPL[37]:1

Can't assign default value AND include species metadata within
@speciesbeginblockTrying to define this reaction network, where
begin ... endblock syntaxE(t)is given a default value as well as metadata (description, tunable)will generate the following error:
Combination of
beginblock, default species assignment, and extra metadata produce the errorIt seems this is a problem with how the DSL is parsing the new
beginblock syntax.Using this syntax and giving a default value, OR metadata, doesn't seem to produce an error. Only the combination of these two specie specifications within a
beginblock produces the error.Additionally, it only affects the
@speciesblock, not@parametersspecies, and uses both for the@parameters, doesn't error.Environment (please complete the following information):
