HOWTO make your first bond application

Create a directory or go to bond/example/simple.

$mkdir simple

Create a postgres database.

$createdb -U postgres bondsimple

This example use the superuser postgres but you can create your own user.

You may have also to edit postgresql.conf to enable tcp connection.

tcpip_socket = true

And pg_hda.conf to enable connection from localhost.
The next line alow every connection from localhost for any user to connect without password, quite safe for personal linux box.

host    all         all         127.0.0.1         255.255.255.255   trust

Create your database stucture file.
Or copy it from 'bond/example/simple/simple.sql'.
A simple one look like:

CREATE TABLE "paymenttype" (
    "id"            serial primary key,
    "description"   text,
    );

CREATE TABLE "payment" (
      "id"            serial primary key,
      "paymenttypeid" integer NOT NULL
                  constraint ref_paymenttype references paymenttype (id),
      "paymentdate"   date default date(now()),
      "amount"        double precision default '0',
      "note"          text
    );

Insert it into your database.

$psql -f simple.sql -U postgres bondsimple

Modify the 'bondfronted.conf'.
Important values are :

#to connect to postgres
db_host = localhost
db_username = postgres
db_password =
db_name = bondsimple

#to enable debug
debug_enabled = true 
debug_stream_stdout = stdout
debug_stream_stderr = stderr
debug_breakonerror = false
debug_breakonwarning = false
debug_level = 90

#to use gtk
uiplugin = gtk

#the name of your main xml file
bondxml = simple.xml

#dtd validation is a good idea to find error in xml
dtd_validation = true

Create your xml main file.
Or copy it from 'bond/example/simple/simple.xml' for the full code which is explained in the next pages.
A realy simple one looklike:

<!DOCTYPE bond SYSTEM "../../bond-2.1.dtd">

<bond
    xmlns="http://bond.treshna.com/ns/v2.0"
	xmlns:xi="http://www.w3.org/2003/XInclude">
	
	<project name="Simple bond example" defaultvisible="false" 
            author="treshna Enterprises Ltd"/>
	
            <window name="payment-win" 
                  title="Payment details" visible="true">
            </window>
</bond>

Now you are ready to see your first blank window, run bondfronted in the directory.

$bondfronted
