history

Project history and usage

astgen is a Joern-related AST generator package for producing JSON AST output for JavaScript and TypeScript. The original standalone repository is now archived and points to joernio/astgen-monorepo.

Project history

The original joernio/astgen repository describes the package as generating AST in JSON format for JavaScript and TypeScript. GitHub now marks that repository archived, and its README directs future work to joernio/astgen-monorepo.

The replacement monorepo reframes astgen as a family of language-specific AST generators for the Joern code analysis platform. Its README lists ABAP, .NET, Go, JavaScript/TypeScript, Ruby, Rust, and Swift generators, each with its own build system, dependencies, tests, and release workflow.

Adoption history

Public adoption evidence is thin: the supplied facts show a Homebrew formula, while the original repository has a small public footprint. The package is best understood as a Joern ecosystem utility rather than a broad standalone developer tool.

How it is used

Package users invoke the astgen executable to produce AST JSON for JavaScript/TypeScript workflows. In current upstream development, users should expect language-specific directories and prefixed release tags in the monorepo rather than all work happening in the archived standalone repository.

Why package nerds care

The interesting package-manager detail is the repository transition: a Homebrew package points at a historical standalone tool, while upstream now collects multiple AST generators under one monorepo with per-language releases and checksums.

That makes source provenance and release-tag selection more important than the package's public popularity.

Timeline

  • 2026: joernio/astgen was archived and its README directed users to joernio/astgen-monorepo.
  • 2026: astgen-monorepo README documents independently versioned language generators and prefixed release tags.

Related projects

  • Joern is the code analysis platform named by the monorepo README as the consumer context for the AST generators.
  • javascript-astgen in the monorepo is the closest successor to the standalone JS/TS astgen package.
  • Other monorepo siblings include abap-astgen, dotnet-astgen, go-astgen, ruby-astgen, rust-astgen, and swift-astgen.
