Our TOML parser doesn't associate source lines to the parsed data structure, so there's no easy solution for the short term. We do get source positions when the TOML syntax is wrong.

I made a PR on TOML for that pmderodat/ada-toml#14

[pmderodat]

Hello! I’ve created a MR (pmderodat/ada-toml#15) to preserve source location information in TOML values: before I merge it to the master branch and create a new ada-toml release, would you be okay to have a look and give me some feedback, to make sure what I did is useful? Thanks!
