| − | Good idea but why do ddp ? That's deleting a line and pasting it back :). |
||
| − | <map> <CS-j> kJj would suffice. The last j will leave the cursor just below the joined line. |

| − | I know it's useful and often tempting to combine code and comments onto one line, but seeing a macro for it suggests it will happen very frequently. |

| − | |||
| − | When two separate things (namely, code and comments) are on the same line, your source diffs start to lose meaning. What changed between two versions of a file? The code or the comment? There's also a tendency to include longer comments, so you end up with things like below, which are a mess when you want to modify the comment. |

Tip: #1050 - Move comment line to end of next line
Created: November 17, 2005 7:04 Complexity: basic Author: matahijau Version: 5.7 Karma: 0/9 Imported from: Tip#1050
Let's say you have some C or Java that looks like this:
// get the age of the person age = person.getAge();
If you want to compact your code a bit you might want to stick the comment at the end of the statement instead of on its own line. Essentially you want to "join up":
map <C-S-j> kddpkJ
Used on the example above by placing the cursor on the second line and typing ctrl-shift-j, you will now have:
age = person.getAge(); // get the age of the person
ddp is used to swap the lines before joining so the comment line is at the end of the newly joined line.
Comments
A better way of swapping lines is to use
:m+ :m-2
Hence, modifying "map <C-S-j> kddpkJ" and maintaining cursor position:
nmap <C-S-j> mz:m-2<CR>J`z
