vim: delete all blank space until next non-blank character

问题

Say I have the following code:

<p>
    Hello
</p>

And I want to make it

<p>Hello</p>

I would like to put the cursor in normal mode at the end of line 1, so on the ' > ' and have a command to delete all spaces until the next character. The closest I can think of is the motion

d/Hello

which deletes everything until Hello but the issue is that it deletes also the character under the cursor (the ' > ') so I end up with

<pHello
</p>

How would you do that?

回答1:

One way when you won't need to repeat this action many times.

JxJx

Explanation:

J           # Join current line with next one but substitute end of line with a space.
x           # Remove the space.
Jx          # Repeat same process for last line.

There's a tag text-object in vim:

put cursor within tag, press vat to select entire tag
press :, it becomes :'<,'>
type j, it becomes :'<,'>j
press Enter to join lines

:help v_at

at          "a tag block", select [count] tag blocks, from the
            [count]'th unmatched "<aaa>" backwards to the matching
            "</aaa>", including the "<aaa>" and "</aaa>".
            See |tag-blocks| about the details.
            When used in Visual mode it is made characterwise.

When standing anywhere in the second line (the one that says Hello), press the following keys: ^d0vatgJ. Simply explained:

^ will go to the first non-whitespace character, H
d0 will delete to the beginning of the line
vat will select the entire tag
gJ will join all the lines without inserting spaces

If you start on the H, you can skip the ^ part.
