What is a Snippet?
Snippets are little piece of code which are used many times in different projects. The snippets panel will help you to mmage this library (snippets are at least a code library).

How to Use in SEPY?
First you must open the Snippt panel from the panels list.
If you never use this panel you must first set a snippet base directory. This must be a valid directory on your hard disk, where all the snippets will be saved an managed by SEPY.
It is recomended to use a new empty directory for this. (Note that also after deleting a snippet, the file won’t be deleted, but only hidden from the panel and renamed from the filsystem).

Create a Snippet
From the contextual menu you can now manage the snippets panel adding folders and snippets.
Create a new snippet, chose a snippet name and then write into the just created file your snippet code. You can write anything you want in the snippet file (next time you will insert this snippet in a opened file all the code you wrote here will be inserted completely).

There also magic words which can be used in a snippet and they are:
@@variableName@@

This is, any word which start with a double “@@” and ends with a double “@@” is recognized as variable.
Next time you will use the snippet, sepy will ask you with which value you want to replace this variable. So, all the occurrences of @@variableName@@ will be replaced with this new value.

@@variableName=[defaultValue]@@

This is another way to specify a variable.
but in this way you also set a default value, which will be displayed by default in the snippet dialog when you want to insert the snippet.

This is a sample snippet:

var gatewayUrl:String = "@@gatewayUrl=[http://localhost/flashservices/gateway]@@";
NetServices.setDefaultGatewayUrl(gatewayUrl);
var conn = NetServices.createGatewayConnection();
var serv = conn.getService("@@serviceName@@", @@responder=[this]@@);


Which will produce this dialog when you’re going to insert the snippet:

Note
This dialog will appear only if you have set at least one variable in the snippet. For every variable set the value you want to assign, then press “Ok” and all the new code will be inserted in the current document
