## Project history and usage

dhall-toml is the Dhall converter package for TOML. It occupies the same ecosystem slot as dhall-json, but for projects whose downstream tools expect TOML rather than JSON or YAML.

### Project history

The dhall-haskell repository lists dhall-toml as one of its maintained packages. The package README says it provides a Dhall-to-TOML compiler, shows dhall-to-toml output, and includes a roadmap noting minimal dhall-to-toml and minimal toml-to-dhall support while schema inference and docs.dhall-lang.org documentation remain incomplete.

### Adoption history

Compared with dhall-json, the official evidence for broad adoption is thin: the supplied package facts list Homebrew packaging only. That matches the package's own roadmap language, which presents it as a useful but less complete integration in the Dhall converter family.

### How it is used

The documented path is to pipe a Dhall record into dhall-to-toml and receive TOML key-value output. The companion toml-to-dhall command exists in the package facts and README roadmap, but the official README signals that TOML-to-Dhall schema inference is not complete.

### Why package nerds care

dhall-toml is interesting mainly as a packaging signal: once a configuration language has a standard command-line compiler, package ecosystems tend to sprout format-specific bridge binaries for every configuration format with users. Here the bridge is real, but the source-backed history is modest.

### Timeline

- 2026: dhall-haskell lists dhall-toml among its package set.
- 2026: The dhall-toml README roadmap marks minimal dhall-to-toml and toml-to-dhall work while leaving schema inference and official docs unfinished.

### Related projects

- dhall-json is the mature JSON/YAML sibling; dhall-bash and dhall-lsp-server cover shell and editor workflows in the same dhall-haskell repository.
