The part of Pluto analyzing expression and determining their order and graph has been recently moved to separate packages that are standalone registered in General:

> [@\[ANN\] ExpressionExplorer.jl and PlutoDependencyExplorer.jl – the internal reactivity algorithm of Pluto!](https://discourse.julialang.org/t/ann-expressionexplorer-jl-and-plutodependencyexplorer-jl-the-internal-reactivity-algorithm-of-pluto/109068):

> We just released two new packages! tada[ExpressionExplorer.jl](https://github.com/JuliaPluto/ExpressionExplorer.jl) (EE) – find all variables assigned and referenced in a piece of code. [PlutoDependencyExplorer.jl](https://github.com/JuliaPluto/PlutoDependencyExplorer.jl) (PDE) – sort a list of codes by execution order Both packages are quite small and load fast, with minimal dependencies. The packages were part of [Pluto’s](https://plutojl.org) source code, but we decided to release them separately so that they can be used in other projects! ExpressionExplorer Find all variables referenced and defined in an expression. Thi…

You might have a look there for more details or directly use them for your use case if relevant!
