It also supports advanced features like inlining of library code (so you can keep DRY) as well as avoiding unnecessary document modification. Couchview also solves a problem with CouchDB's view API, which only provides access to the final reduce side of any views which have both a map and a reduce function defined. The intermediate map results are often useful for development and production. CouchDB is smart enough to reuse map indexes for functions duplicated across views within the same design document. For views with a reduce function defined, Couchview creates both a reduce view and a map-only view, so that you can browse and query the map side as well as the reduction, with no performance penalty. == Example == couchview push foo-project/bar-views baz-database This will push the views defined in foo-project/bar-views into a database called baz-database. Couchview expects the views to be defined in files with names like: foo-project/bar-views/my-design/viewname-map.js foo-project/bar-views/my-design/viewname-reduce.js foo-project/bar-views/my-design/noreduce-map.js Pushed to => http://localhost:5984/baz-database/_design/my-design And the design document: { "views" : { "viewname-map" : { "map" : "### contents of view-name-map.js ###" }, "viewname-reduce" : { "map" : "### contents of view-name-map.js ###", "reduce" : "### contents of view-name-reduce.js ###" }, "noreduce-map" : { "map" : "### contents of noreduce-map.js ###" } } } Couchview will create a design document for each subdirectory of the views directory specified on the command line. == Library Inlining == Couchview can optionally inline library code into your views so you only have to maintain it in one place. It looks for any files named lib.* in your design-doc directory (for doc specific libs) and in the parent views directory (for project global libs). These libraries are only inserted into views which include the text //include-lib or #include-lib Couchview is a result of scratching my own itch. I'd be happy to make it more general, so please contact me at jchris@grabb.it if you'd like to see anything added or changed. GEN helpstring.gsub(/^ /, '') end end end end
