Compiler

Tooling

  • The dylan command-line tool has had various improvements, including:

    • Simplified workspace model

    • Simplified process to publish packages

    • Packages installed locally in workspace directory by default

    • Global package installation follows the XDG Base Directory Specification.

    • Symlink points to current installed version of packages, for easier tooling.

    Full documentation is here.

  • The make-dylan-app program has been removed and is replaced by dylan new application and dylan new library.

Library Updates

Submodules

Open Dylan uses Git submodules to pull in some dependencies and user programs may depend on these for now. The notable changes in those submodules are listed below:

  • sphinx-extensions - Improvements to DRM references.

  • dylan-tool - See above.

  • collection-extensions - The split-at function has been removed. Use split instead. Documentation improvements.

  • command-line-parser - Minor bug fix to add a missing newline when no subcommand is provided.

  • json - Fixed sort-keys? option for recursive print-json calls.

system Library

  • A bug in locator-directory for relative directory locators was fixed.

  • The run-application function is now fully documented.

  • A follow-links?: keyword argument has been added to the file-exists? function. The default is true, for compatibility with the previous behavior.
