Creating a Store Part 12

To create a store part, take the following steps using Newton Toolkit version 1.5

or greater:

■ Create a new project.

■ Select the Store Part radio button in the Output Settings dialog box. NTK disables

all other settings in this dialog box when the Store Part option is selected.

■ Conﬁgure the Package Settings dialog box as you normally would. The name

speciﬁed in this dialog box identiﬁes the store part to the system in much the

same way that a package name identiﬁes a package; thus, you need to ensure the

uniqueness of this identiﬁer by basing it on your developer signature in some way.

■ Add a new text ﬁle to the project. You’ll add to this document the NewtonScript

code that creates one or more soups to reside on the store part.

At compile time, NTK provides a global variable named

theStore, which

represents the store part (package store) you are building. Any changes made to

this variable are reﬂected in the store part that is produced as the output of the build

cycle. Thus, to create your read-only soup, you can add to the text ﬁle some

NewtonScript code similar to the following example:

// some useful consts; note use of developer signature

constant kStoreName := "MyStore:MYSIG" ;

constant kSoupName := "MySoup:MYSIG" ;

constant kSoupIndices := '[] ;

// theStore is a global var provided by NTK

theStore:SetName(kStoreName) ;

// create the soup but don’t xmit at build time

local soup:=theStore:CreateSoupXmit(kSoupName,

kSoupIndices, nil);

// add a couple entries

soup:Add({anInteger: 1}) ;

soup:Add({anInteger: 2}) ;

When the package is built, NTK incorporates the store part in it.
