Question

As I develop more with vim, I find myself wanting to copy in blocks of useful code, similar to ‘templates’ in Eclipse.

I was thinking of making a separate file for each code chunk and just reading them in with

:r code-fornext 

but that just seems kind of primitive. Googling around I find vim macros mentioned and something about ‘maps’ but nothing that seems straightforward.

What I am looking for are e.g. something like Eclipse’s ‘Templates’ so I pop in a code chunk with the cursor sitting in the middle of it. Or JEdit’s ‘Macros’ which I can record doing complicated deletes and renaming on one line, then I can play it again on 10 other lines so it does the same to them.

Does vim have anything like these two functionalities?

Answer 1

To record macros in Vim, in the command mode, hit the q key and another key you want to assign the macro to. For quick throw away macros I usually just hit qq and assign the macro to the q key. Once you are in recording mode, run through your key strokes. When you are done make sure you are back in command mode and hit q again to stop recording. Then to replay the macro manually, you can type @q. To replay the previously run macro you can type @@ or to run it 10 times you could type 10@q or 20@q, etc..

In summary:

+----------------------------------+-------------------------------------+ | start recording a macro          | qX (X = key to assign macro to)     | +----------------------------------+-------------------------------------+ | stop recording a macro           | q                                   |   +----------------------------------+-------------------------------------+ | playback macro                   | @X (X = key macro was assigned to)  | +----------------------------------+-------------------------------------+ | replay previously played macro   | @@                                  | +----------------------------------+-------------------------------------+ 

In regards to code chunks, I have found and started using a Vim plug-in called snipMate, which mimics TextMate’s snippets feature. You can get the plug-in here:

And a short article on using snipMate (along with a short screencast showing it in use):
