It exists for the corner of operations culture where Bash remains the glue, but users still want Dhall's type checking and import discipline before values enter a script. ### Project history The dhall-haskell repository lists dhall-bash as one of the packages maintained in the main Haskell implementation tree. Its package README describes a Dhall-to-Bash compiler that marshals Dhall values into Bash scripts, with support focused on primitive values, lists, optional values, and records from normalized expressions. ### Adoption history Dhall's official integration guide frames Bash output as one of the external executable paths for projects that do not read Dhall directly. The supplied package facts show dhall-bash packaged by Homebrew, Nix, and Arch, which fits its niche as an optional companion command rather than the default Dhall entry point. ### How it is used Users pipe or redirect Dhall expressions into dhall-to-bash, optionally asking it to emit Bash declarations. The official README examples show scalar output, readonly variable declarations, arrays, and associative arrays that can be evaluated by a shell script. ### Why package nerds care dhall-bash matters to package nerds because it captures a recurring packaging pattern: a language ecosystem grows small format-specific executables so package managers can expose only the integration a user needs. It lets shell-heavy deployments consume typed configuration without pulling an application into a Dhall binding. ### Timeline - 2017: dhall-haskell public releases included the multi-package Dhall toolchain. - 2026: The official docs still present Bash generation as an external executable integration path. ### Related projects - dhall-json, dhall-yaml, dhall-toml, dhall-nix, and dhall-lsp-server are sibling packages in dhall-haskell. The language-independent dhall-lang repository defines the shared standard and documentation. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** dhall-bash - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - dhall-bash: normalized package name match | nixpkgs package indexes: dhall-bash from https://raw.githubusercontent.com/NixOS/nixpkgs/master/pkgs/top-level/all-packages.nix - pacman - dhall-bash - 1.0.41-216: normalized package name match | Arch Linux sync databases: dhall-bash from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | Compile Dhall to Bash | https://dhall-lang.org ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [cabal-install](https://www.automicvault.com/pkg/brew/cabal-install/) - Build dependency declared by Homebrew. - [ghc](https://www.automicvault.com/pkg/brew/ghc/) - Build dependency declared by Homebrew. - [dhall-json](https://www.automicvault.com/pkg/brew/dhall-json/) - Shares the same upstream source repository. - [dhall-lsp-server](https://www.automicvault.com/pkg/brew/dhall-lsp-server/) - Shares the same upstream source repository. - [dhall-toml](https://www.automicvault.com/pkg/brew/dhall-toml/) - Shares the same upstream source repository. - [dhall-yaml](https://www.automicvault.com/pkg/brew/dhall-yaml/) - Shares the same upstream source repository. - [configen](https://www.automicvault.com/pkg/brew/configen/) - Shares av.db curated category or tags: cli, code-generation, configuration, developer-tools. - [ragel](https://www.automicvault.com/pkg/brew/ragel/) - Shares av.db curated category or tags: cli, code-generation, compiler, developer-tools. - [autogen](https://www.automicvault.com/pkg/brew/autogen/) - Shares av.db curated category or tags: cli, code-generation, developer-tools. - [blueprint-compiler](https://www.automicvault.com/pkg/brew/blueprint-compiler/) - Shares av.db curated category or tags: cli, code-generation, compiler, developer-tools. - [butane](https://www.automicvault.com/pkg/brew/butane/) - Shares av.db curated category or tags: cli, configuration, developer-tools. - [config-file-validator](https://www.automicvault.com/pkg/brew/config-file-validator/) - Shares av.db curated category or tags: cli, configuration, developer-tools. - [counterfeiter](https://www.automicvault.com/pkg/brew/counterfeiter/) - Shares av.db curated category or tags: cli, code-generation, developer-tools. ## Combined YAML source View the package source record on GitHub.
