vim tip: generate get-set functions

Been programming in java now for some time. And, as it happens java needs a lot of get-set functions. Yes, I know you can generate them easily in Eclipse, but as it happens I love vi (or may be I am too lazy to switch ;)) So, here is a tip for all those vi lovers out there. To generate get set functions from your variable definitions:

1. Write all variable definitions.
Example:

  1 public class KeywordDimension extends Model implements Serializable
  2 {
  3     private Long m_vendorId;
  4     private Long m_keywordId;
  5     private String m_vendor;
  6     private String m_keyword;

2. Copy them once more below where you want to generate get-functions.

  1 public class KeywordDimension extends Model implements Serializable
  2 {
  3     private Long m_vendorId;
  4     private Long m_keywordId;
  5     private String m_vendor;
  6     private String m_keyword;
  7     
  8     private Long m_vendorId;
  9     private Long m_keywordId;
 10     private String m_vendor;
 11     private String m_keyword;

3. Run this substitute command in vi:

:8,11s/private \(.*\) m_\(.*\);/public \1 get\2() \r    {\r        return m_\2;\r    }/gc

4. You will get this:

  1 public class KeywordDimension extends Model implements Serializable
  2 {
  3     private Long m_vendorId;
  4     private Long m_keywordId;
  5     private String m_vendor;
  6     private String m_keyword;
  7     
  8     public Long getvendorId()
  9     {
 10         return m_vendorId;
 11     }
 12     public Long getkeywordId()
 13     {
 14         return m_keywordId;
 15     }
 16     public String getvendor()
 17     {
 18         return m_vendor;
 19     }
 20     public String getkeyword()
 21     {
 22         return m_keyword;
 23     }

4. Now run this to replace getk by getK (capital) for example:

:8,23s/get\([a-z]\)/get\u\1/gc

You get this:

  1 public class KeywordDimension extends Model implements Serializable
  2 {
  3     private Long m_vendorId;
  4     private Long m_keywordId;
  5     private String m_vendor;
  6     private String m_keyword;
  7     
  8     public Long getVendorId()
  9     {
 10         return m_vendorId;
 11     }
 12     public Long getKeywordId()
 13     {
 14         return m_keywordId;
 15     }
 16     public String getVendor()
 17     {
 18         return m_vendor;
 19     }
 20     public String getKeyword()
 21     {
 22         return m_keyword;
 23     }

Voila! Just two vim substitutes and you are done! Repeat similar stuff for sets, replacing get by set, and substituting by assignments:

:25,28s/private \(.*\) m_\(.*\);/public void set\2(\1 \2) \r    {\r        m_\2 = \2;\r    }/gc
:25,40s/set\([a-z]\)/set\u\1/gc
