" Any fool can write code that a computer can understand.

Good programmers write code that humans can understand. "

--- Martin Fowler, Refactoring: Improving the Design of Existing Code

ABAP pretty printer is good for code but not supportive for data declarations.



As a result ABAP code often tends to need more labour to maintain.

I therefore wrote 3 Clipboard utilities. These are in a ZIP file and are available as a download.

1. YClipJNC based on http://sap.ionelburlacu.ro/abap/sap2/Beautify_Source_Code.html

but improved to include table~column half-line commenting.

Take any ABAP code (should have survived syntax check) including that "." DOT terminator.

Copy to Clipboard & F8 on YClipJNC will create the beautiful version in clipboard

ready for pasting back.

The big advantage is that you can send for beautification only portions of code

- this is vital in maintaining someone else's badly written code.

2. YClip2JNC is for Internal Table declarations only, with existing comments

Aligns everything nicely.

3. YClip3JNC is to create a Commented CALL FUNCTION Pattern.

Try with "CS_BOM_EXPL_MAT_V2"

The pattern is ready in clipboard for pasting appropriately.



These 3 utilities should give a big boost to good clean commented ABAP code. No excuses for not half-line commenting!

* This program takes ABAP code in ClipBoard, and does the following:

* - Attempts to move comments to the end of the line

* - Adds comments (table name) for the tables listed after a TABLES

* statement if the line has not been commented already.

* - Adds comments (field name) for data elements, parameters, and



* select-options that are defined using the LIKE or FOR statement

* - For ENDLOOP/ENDSELECT adds comment identify the LOOP/SELECT

* that is being closed

* - For FORM/ENDFORM adds comment identify the FORM that is being

* closed

* - Calls function PRETTY_PRINTER to do the SAP standard pretty print

* after the custom comments have been created

* Returns Modified Code Via ClipBoard
