Snippets

SNIPPETS

A snippet is a sort of code template or skeleton that allows you to quickly set up a commonly used code fragment like a subprocedure definition (in ILE RPG). Snippets are available from WDSC 7.0 up.

This differs from code templates because the code template is invoked by the code completion facility Ctrl+Space.

Code completion with templates requires you to start keying the 'trigger' (in RPG, usually the operation code.)

With snippets, you can have Lpex include anything at all, with no trigger needed aside from the double click on the selected snippet.

• -Right-click in the Snippets view and select Customize...
• -Click the New button and create a New Category
• -Click the New button and create a New Item
• -Click on the snippet and then click the New button that is adjacent to the Variables list

Snippets RPG

You can use the snippets to insert stuff into your program.

To create your own RPG snippets,

• you can open the view in RSE or iSeries Editing perspective,
• select your source,
• then Right Click / Paste in the snippets view, into your Previously created Category.

It will then create a new template.

To use the snippet;

• Open a source member for editing.
• Place the cursor where you want the code.
• Go to the Snippets view, to the Category where the snippet is.
• Double click on the snippet and it appears in the source

Another method is to create a Snippet.

1. Open the Snippets view.
2. Create a new 'Drawer' for your snippets.
3. Copy some source.
4. Right-click in your snippet drawer, paste.
5. This will bring up the snippet creation wizard.

Long Procedure Name

original post [5]

How do I get the PR to stay at the same column position, irrespective of what name I use for the procedure ?

Use:

D ${Procedure}...
                          PR  

Otherwise the procedure name has to always be 12 characters in length. With the elipsis (...) it can be up to 60 odd characters in length.
