This is a view server for the CouchDB document-oriented database. It follows
the specifications set out at:
http://wiki.apache.org/couchdb/View_server

For more information about CouchDB see:
http://couchdb.apache.org/

This project consists of two assemblies: ViewServer and ViewHelpers.

 - ViewServer is a console driver application which can be executed
   by CouchDB to execute map/reduce operations. The driver accepts
   one command line argument: the .NET language to accept as input.
   This should be one of the values supported by the 
   System.CodeDom.Compiler system. By default these are "CSharp", "JScript",
   and "VB". You can add support for a particular language to CouchDB by
   adding a line to the [query_servers] section of the local.ini file:

      [query_servers]
      csharp=/path/to/ViewServer.exe CSharp
      vb=/path/to/ViewServer.exe VB

 - ViewHelpers contains some helper classes for building views in .NET
   languages. The helpers include:
   * A singleton class attribute TheCouchDBView which is applied to the class
     containing the map or reduce function.
   * Interface declarations IMapFunctor, IReduceFunctor and IReReduceFunctor
     which must be implemented to support the respective functionality.
   * The singleton class Emitter which implements the Emit function which
     is used for map operations.
   See SampleViewFunctions.txt for some quick examples.

The code is dynamically compiled and linked into in-memory assemblies. These
assemblies are cached until a 'reset' command is received from CouchDB. 
As a result, compiling is always a one-time cost.

As a fun side note, using C# as the target language works perfectly well
under Mono on Linux. Your milage with other languages may vary.

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
