== Downloading and Installing Exodus ==

http://code.google.com/p/exodusdb/downloads

== C++ Compiler ==

If you want to write or compile Exodus programs on Windows you need a Microsoft C++ compiler. You don't need a C++ compiler to just used the Exodus command line to access the database or run prepackaged Exodus programs.

=== MSVC ===

*Visual Studio 2003 Professional
*Visual Studio 2005 Professional
*Visual Studio 2005 Express (Requires Platform SDK)
*Visual Studio 2008 Express (works)
*Visual Studio 2010 Express (not known)

A standard install of the free VS Express C++ preferably in the default location on C: or parallel default location but on the same drive as Exodus. No need for any SQL or options.

== Postgresql ==

If you want to use Exodus to provide multivalue database functionality then you must already have or install a PostgreSQL database.

http://www.postgresql.org/download/windows

Postgres does not have to be on the same server as Exodus but if not, you will not be able to use dictionary entries that are written in Exodus code.

=== Windows Postgres plugin ===

At the time of writing, the Windows installer does not install the postgres plugin automatically so you need to do something like the following.

 copy "C:\Program Files\Exodus\10.10\lib\pgexodus-8.dll" "C:\Program Files\PostgreSQL\8.4\lib\pgexodus.dll"

 copy "C:\Program Files\Exodus\10.10\lib\pgexodus-9.dll" "C:\Program Files\PostgreSQL\9.0\lib\pgexodus.dll"

=== Postgres configuration ===

By default, Exodus assumes the following postgres configuration. This of course is not secure and should only be used for testing purposes.

 host=127.0.0.1 port=5432 dbname=exodus user=exodus password=somesillysecret connect_timeout=10

The following Exodus command prompts for a postgres admin user and password and creates the default database and password.

 configexodus

Alternatively, you can use any Postgres utility to create an initial database and user. The user should have database creation rights if you wish to be able to create and drop databases from Exodus but there is no need for the user to have admin rights.

 notepad %USERPROFILE%\.exodus

 host=127.0.0.1 port=5432 dbname=exodus user=exodus password=somesillysecret connect_timeout=10

The following environment variables can override default and .exodus parameters on a one by one basis.

 set EXODUS_HOST=127.0.0.1
 set EXODUS_PORT=5432
 set EXODUS_DBNAME=exodus
 set EXODUS_USER=exodus
 set EXODUS_PASSWORD=somesillysecret
 set EXODUS_TIMEOUT=10

== Using Exodus ==

Start, All Programs, Exodus, Exodus Console

Try the following commands.

{|
!Command 		!!Comment
|-
|configexodus           ||One time setup of default database and user in postgres (exodus and exodus)

|<U>EDITING AND COMPILING</U>

|createindex test_clients CLIENT_TYPE	||speeds up select commands on the indexed fields in the traditional way

|}

If you get the following error then you have not completed the installation of pgexodus.dll function in postgres as described in the section on postgres above.

PGRES_FATAL_ERROR: ERROR:  function exodus_extract_text(bytea, integer, integer, integer) does not exist

== Documentation how to program in Exodus ==

No programming manual yet but there is a list of functions in wiki at

http://code.google.com/p/exodusdb
[[Unorganised notes about programming in Exodus]]

== Source code and Exodus development environment ==

http://code.google.com/p/exodusdb has latest full source code and tools to build exodus from scratch on all supported platforms.

include\exodusfuncs.h lists the functions that simulates pickish syntax as close as can be achieved. The functionality however should be identical.

include\exodusmacros.h lists a few keywords to simplify programming for application programmers not interested in the raw power of c++.

include\mv.h lists the massive var class definition that defines how to write pick in oo object.method() style syntax.

Following is not up to date but still informative.
