I am passing named variable/constraints to JuMP. Is there a way to track the variable/constraint _name_ linked to the row f[#] which is what is reported by PATH (looks like unnamed rows as in this [example](https://github.com/chkwon/PATHSolver.jl?tab=readme-ov-file#use-with-the-c-api) without names)?
I am using the PATH solver, via what I believe is a codestack that goes something like JuMP-\>MOI-\>PATHSolver-\>PATH. The output from PATH includes "label"s with the largest error per iteration which are numbered by model row.
It seems like the transformation from name to # is happening somewhere along the stack because the [PATH documentation](https://www.gams.com/latest/docs/S_PATH.html#PATH_LOG_FILE) shows named labels for a model defined more directly, and JuMP obviously knows the variable names and margin values in the solution…
Not sure right now how to provide a MRE from our [metaprogramming structure](https://github.com/anthofflab/MPSGE.jl/blob/main/src/build/build_marketclearance.jl), but with a @variable(model, jump\_var) and an jump\_ex expression, we set
@constraint(jm, jump\_ex ⟂ jump\_var)
Thanks and apologies for any misunderstandings in my question.

Not really. I’ve opened an issue:

This is now supported in the latest release of PATHSolver.jl.
