Visual C++ compiler

If you want to program in Exodus then you need to install an MS C++ compiler.

If you have VS C++ 2003/2005/2008 already installed then you have nothing to do, otherwise do a standard install of free VS Express C++ (2008 currently) 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.

Postgres

If you want to use Exodus to operate a Pick-style database then you must already have or install a postgres database.

If you need calculated dictionary entries or are not prepared to do the simple installation of the postgres exodus plugin yourself then the postgres server needs to run on the same host as exodus, otherwise you can use any remote postgres server version 8+ on any os.

If you need to install Postgres then do a standard install of the current version (8.3) preferably in the default location on C: or parallel default location but on the same drive as Exodus.

Exodus needs to be granted a postgres username, password and database to work in - and preferably rights to create databases and users. By default, Exodus uses the following to connect or you can put a file called .exodus containing some similar line in your home directory (%USERPROFILE% on windows).

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

Use the installed PGAdminIII or your preferred postgres client to create the chosen user and database. If you prefer SQL, use the following:

CREATE ROLE exodus LOGIN PASSWORD 'somesillysecret' CREATEDB CREATEROLE;
CREATE DATABASE exodus WITH ENCODING='UTF8' OWNER=exodus;

Sorry but just at the moment you have to install the pgexodus.dll plugin for postgres manually.

copy pg exodus.dll from the exodus bin directory to the postgres lib directory \Program Files\8.3\lib and then using PGAdminIII as postgres superuser run the following SQL

[pgexodus.dll for postgres]

Downloading and Installing Exodus

Using Exodus

Start, Run, All Programs, Exodus, Exodus Command Prompt

Try the following commands.

Command	Comment
EDITING AND COMPILING
edit test	Creates a skeleton test.cpp file using nano editor with exodus. edit will compile on exit if saved, so make some change before you exit.
test	Run it
compile test	compile without editing
edit testsort	Browse a sample exodus program showing all fundamental database operations including dictionaries and list.
DATABASE OPERATIONS
testsort	Run it to generate some data and inspect the output
listfiles	quick tool avoiding need to use any database client
list test_clients	text output - no page/column headers just yet sorry
list test_clients (H)	html output (port of a LIST replacement in heave use since 2000)
list dict_test_clients	nb the underscore after "dict" is required - dict(space)voc wont work
list dict_voc	if you understand this then you understand your pick
edit test_clients SB001	you can edit data or dictionaries directly
delete test_clients SB001	useful command line tool
createfile tempfile	ditto
deletefile tempfile	ditto
createindex test_clients CLIENT_TYPE	speeds up select commands on the indexed fields in the traditional way
deleteindex test_clients CLIENT_TYPE	filenames are case insensitive, keys and fieldnames are not

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

If you have Visual Studio installed try the test project (VS2005+).

Start, Run, All Programs, Exodus, Blank Visual Studio Solution. To run and avoid the "cannot find exodus.dll" message, you have to set the project configuration properties, Debugging, Environment to PATH=..\..\bin.

Documentation how to program in Exodus

Sorry nothing yet but you might be able to work out what functions are available from the following:

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.

Unorganised notes about programming in Exodus

Source code and Exodus development environment

http://svn.neosys.com/svn/trunk has full source code and tools build exodus from scratch. Also a script make.sh for a basic build and install on linux (redhat but probably works with minor tweaks anywhere).

This devwiki site was initially written more in mind with BUILDING exodus. It will now be updated to reflect USING exodus.
