Sinatra 0.9.1 released!

Sinatra 0.9.1 is a feature release. Highlights include support for
running on Ruby 1.9.1, a shiny new API for extensions/plugins, and
better support for building Rack middleware. This release is backward
compatible with 0.9.0 and 0.3.x.

gem install sinatra

From the CHANGES file:

  • Sinatra now runs under Ruby 1.9.1 [#61]

  • Route patterns (splats, :named, or Regexp captures) are now passed
    as arguments to the block. [#140]

  • The “helpers” method now takes a variable number of modules along
    with the normal block syntax. [#133]

  • New request-level #forward method for middleware components: passes
    the env to the downstream app and merges the response status, headers,
    and body into the current context. [#126]

  • Requests are now automatically forwarded to the downstream app when
    running as middleware and no matching route is found or all routes

  • New simple API for extensions/plugins to add DSL-level and
    request-level methods. Use Sinatra.register(mixin) to extend the DSL
    with all public methods defined in the mixin module; use
    Sinatra.helpers(mixin) to make all public methods defined in the mixin
    module available at the request level. [#138] See for details.

  • Named parameters in routes now capture the “.” character. This
    makes routes like “/:path/:filename” match against requests like
    “/foo/bar.txt”; in this case, “params[:filename]” is “bar.txt”.
    Previously, the route would not match at all.

  • Added request-level “redirect back” to redirect to the referring URL.

  • Added a new “clean_trace” option that causes backtraces dumped to
    rack.errors and displayed on the development error page to omit
    framework and core library backtrace lines. The option is enabled by
    default. [#77]

  • The ERB output buffer is now available to helpers via the @_out_buf
    instance variable.

  • It’s now much easier to test sessions in unit tests by passing a
    “:session” option to any of the mock request methods. e.g.,
    get ‘/’, {}, :session => { ‘foo’ => ‘bar’ }

  • The testing framework specific files (‘sinatra/test/spec’,
    ‘sinatra/test/bacon’, ‘sinatra/test/rspec’, etc.) have been
    deprecated. See for instructions on
    setting up a testing environment with these frameworks.

  • The request-level #send_data method from Sinatra 0.3.3 has been
    added for compatibility but is deprecated.

  • Fix :provides causing crash on any request when request has no
    Accept header [#139]

  • Fix that ERB templates were evaluated twice per “erb” call.

  • Fix app-level middleware not being run when the Sinatra application
    is run as middleware.

  • Fixed some issues with running under Rack’s CGI handler caused by
    writing informational stuff to stdout.

  • Fixed that reloading was sometimes enabled when starting from a
    rackup file [#110]

  • Fixed that “.” in route patterns erroneously matched any character
    instead of a literal “.”. [#124]

All together, a little over 60 tickets were filed away in lighthouse,
making this one of the most active releases to date:

Thanks to all these folks. Sinatra rocks solid, and is a ton of fun to
