Re: Replace spaces with underscore after some pattern in line

:%s/\(XXX[^ ]*\) /\1_/g

This one replaces just the first space. E.g. the first line becomes:

aaaaaa bbbbbb cccc XXX_aaaaa bbbbbbb

Rather than (notice the second underscore after 'aaaaa'):

aaaaaa bbbbbb cccc XXX_aaaaa_bbbbbbb

I came up with either:

%norm /XXX^Mv$:s/\%V /_/g^M

%V will limit the substitute to the visual selection

Or:

%s/XXX\zs.*/\=substitute(submatch(0), " ", "_", "g")/

 

BTW, the last line is missing an underscore after XXX. Would love to see a simpler command.

Subject: Replace spaces with underscore after some pattern in line

How to replace all of the spaces in each line after XXX string?

Input sample data:

aaaaaa bbbbbb cccc XXX aaaaa bbbbbbb
cccccccc eeeeeeeeee XXX aaa bbbb cccc ddd
aaaa bbbb ddd ee XXX aaa bbb dddd eee

Output sample data:
aaaaaa bbbbbb cccc XXX_aaaaa_bbbbbbb
cccccccc eeeeeeeeee XXX_aaa_bbbb_cccc_ddd
aaaa bbbb ddd ee XXX aaa_bbb_dddd_eee

Hi

to my slight surprise this works:

:%s/\(XXX[^ ]*\) /\1_/g

The reason I had doubts is that the successive replacements start at the beginning of the earlier replacement.

(Sorry about layout. I'm not into this add at the end bit).

regards - Chris
