How can I minimize keystrokes while inserting similar lines in vim?

Sometimes I need to insert some similar lines in a file which differ only in a sequence number. For example,

print "func 1";
print "func 2";
print "func 3";
print "func 4";开发者_Python百科
print "func 5";

Using vim, I end up copy pasting the first line using [yypppp] and then changing the last four lines. This is really slow if you have more lines to insert.

Is there a faster way to do this in vim?


An example of this is:

Initial state

boot();
format();
parse();
compare();
results();
clean();

Final state

print "func 1";
format();
print "func 2";
parse();
print "func 3";
compare();
print "func 4";
results();
print "func 5";
clean();


Record a macro. Here is the workflow for your particular example:

Copy-paste the first line. Then,

qa       : Start recording macro to register a
yy       : Yank current line
p        : Paste current line in line below
/\d      : Search for start of number (you can skip this command, the next command automagically moves the cursor to the number)
C-A      : Control-A increments the number
q        : Stop recording macro
3@a      : Replay macro 3 times

You can replace 3 with any number to keep generating new print lines with incremented numbers.

For your second example, you can just add

j        : Moves one line down

after the yy command, to get alternating lines of commands and print's.


You have plugins that do it. For example, visincr. Visually select your column of numbers, and run :I.

Another way to do it is to record a macro. run qx to start recording macro to register x, yiw to yank word under the cursor, j to go one line down, viwp to paste it, CTRLA to increment the new number, q to stop recording, and then @x to replay contents of register x.


For this particular case, you could use a macro. There's a good write-up of how to do sequence numbers in this post.

You need to change the example in the post to write out the entire line first and then record a macro that copies the line and updates the counter.
