get_assignees tries to read macro input

[schillic]

I get hit by this warning:

ExpressionExplorer.jl/src/explore.jl

Line 177 in 4272b28

@warn "unknown use of `=`. Assignee is unrecognised." ex

┌ Warning: unknown use of `=`. Assignee is unrecognised.
│   ex = :(X')
└ @ ExpressionExplorer ~/.julia/packages/ExpressionExplorer/BGoGa/src/explore.jl:177

The corresponding expression is:

p = @ivp(X' = AX, X(0) ∈ X0)

I presume this means that the parser tries to read X' = AX. But this is inside a macro (from MathematicalSystems), which handles this expression already and returns a result for p. So I think the parser should just let the macro do its job and parse the result instead. Is there a way to say "please execute the macro first"?

Hey! The function get_assignees is not public API, you can find the public API on our README :)

But I also get the warning when computing assignees the usual way:

julia> ExpressionExplorer.compute_reactive_node(:(p = @ivp(X' = AX, X(0) ∈ X0))).definitions
┌ Warning: unknown use of `=`. Assignee is unrecognised.
│   ex = :(X')
└ @ ExpressionExplorer ~/Documents/ExpressionExplorer.jl/src/explore.jl:177
Set{Symbol} with 1 element:
  :p

The warning is safe to ignore (although I am not sure why you're seeing it, @Pangoraw might know), because contents of macros are always ignored:

julia> ExpressionExplorer.compute_reactive_node(:(p = @ivp(X = AX, X(0) ∈ X0))).definitions
Set{Symbol} with 1 element:
  :p

If you want macros to be handled, you have the option to macroexpand before using ExpressionExplorer: https://github.com/JuliaPluto/ExpressionExplorer.jl#macro-calls

Let me know if this helps!

I forgot to mention that I do not use this package directly but saw the warning in Pluto, and narrowed it down to land here.
Thanks for the reply and pointer!

Alright! Try to always write down what steps you took to get to an issue 👍
