" 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 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. ========================================================================================= * REPORT yclipjnc. .
