Version 0.9.0

• Split drom-share into another repository:
  • Use https://github.com/OCamlPro/drom-share by default
  • Add fields share-repo and share-version in drom.toml to manage the
    repo and version of skeletons, independantly of the version of drom
  • Add command-line arguments:
    • --share-version VERSION: set the version of the repo to use (VERSION
      should be a tag). Available in drom project and drom new.
      • Use branch:BRANCH or branch:REMOTE:BRANCH to use a branch
        instead of a tagged version (only to test new versions of drom-share)
    • --share-repo URL: set the git url of the repo to use.
      Available in drom project and drom new.
    • --no-fetch-share: do not access the network with git when looking
      up the latest version (i.e. use the most recent local version)
    • --reclone-share: reclone with git the share repository
  • Repositories are cloned into $HOME/.config/drom/shares/, with a md5
    of their url as directory name
• Support for pin-depends in dependencies:
  • d = { pin = "..." } will translate to [ "d" "..." ]
  • d = { version = "=1.0", pin = "..." } will translate to
    [ "d.1.0" "..." ] (notice the explicit use of = inside the version)
• Automatic use of locked files:
  • opam install is always called with --locked, and will generate a file
    $PROJECT-deps.opam.locked at the root of the source tree
  • If a file $PROJECT-deps.opam.locked is available at the root of the source
    tree, it will be provided to opam install (projects with binaries should
    git add this file, while other projects should .gitignore it)
• Configuration file $HOME/.config/drom/config:
  • Add option git-stage: true/false to decide whether drom should
    call git add and git rm after every modification
• Support for git conflicts in .drom: accept multiple hash for a file
  to decide whether it has been modified by the user or by drom
• Requires use of opam>=2.1
