プロジェクトの歴史

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.

採用の歴史

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.

使われ方

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.

パッケージ好きにとっての重要性

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.
