@matthiasbeyer since this original PR was stale from about 2 years ago, does anything look like adjustments are needed? In the tests I can see it's missing the enum settings file like all other config types seem to have coverage for. Should that be addressed? I probably should version bump the new dependencies added too? |

TOML seems to rely on inference while others are more explicitly typing to ValueKind::I64(value), should I go with the latter?

While looking into version bumping serde_dhall I checked the repo and noticed it's no longer maintained.
The demand for Dhall in config-rs seems low. Perhaps this isn't worth landing into config-rs?

Note this status update from June 2023:
https://github.com/Nadrieril/dhall-rust#status
I am no longer maintaining this project.
I got it to support about 90% of the language but then lost faith in the usability of dhall for my purposes
- Only 1 other user has 👍 the original issue (Nov 2019) requesting Dhall support: Format request: Dhall #123
- The original PR (July 2021) itself was left stale for about 2 years, with the author no longer interested pursuing it.
- The original issue author also expressed a loss of interest in Dhall (March 2021).
- I personally have no interest in the config format myself. I just thought I'd help avoid a feature PR from going stale 😅
Given the above, perhaps Dhall should not be merged into config-rs? The lack of upstream maintenance and demand doesn't seem to justify any additional maintenance burden it may offload onto config-rs project?

Yes, depending on an unmaintained implementation is definitively something we shouldn't rely on, sorry. |

FWIW, it seems that the yaml support has become unmaintained, no commits since July 2021. The developer doesn't have much activity on Github (last active Sep 2022). |
|
FWIW, the upstream Although I now have the time available to resume contributions here, recent experiences have led me to shift my focus away from Closing as there appears to be limited interest/demand in this PR and associated issue that someone else would care to progress it. |

Rebased #218 with conflicts resolved. All credit to @sphw for the actual contribution.
This PR adds Dhall support using serde_dhall, a native Rust implementation of Dhall. Dhall is a functional configuration language designed to make composition of configuration files easier.
Closes #123
