Given the following line:
[aaaa bbbb cccc dddd] [decimal](18, 0) NULL,
How would you replace the spaces only between the firs开发者_开发百科t set of brackets in Vim? What would the /s command look like?
Update:
This is the intend outcome
[aaaa_bbbb_cccc_dddd] [decimal](18, 0) NULL,
The easiest way to do it would be to visually select the contents of the []
ed string and perform the replacement just on that selection:
vi]:s/\%V \%V/_/g
This doesn't work very well if you're trying to do things programmatically, though. In that case, you can match the entire []
ed string and use a replacement expression to construct the result.
:s/\[[^\]]*\]/\=substitute(submatch(0), ' ', '_', 'g')/g
with the normal setting of 'magic' you'd want to do
:s/] \[/][/
or more fancily
:s/]\zs\s\+\ze\[//
or with the magic level explicitly set in the regex
:s/\V]\zs\s\+\ze[//
\zs and \ze limit the substitution to the area that they enclose.
\M turns off magic completely, so every character or character combo not prefixed with \
is taken literally.
'magic' (:help 'magic'
) is a global option that determines how potentially-special characters in regexes are interpreted.
You can always go for interactive find and replace, which can be done with flag c
