How to replace 5 times {} by {foo}
\textstyleCblue{String(string),StringString(String,Sring)}&{string}&
{(string)}&{}\tabularnewline
My RE
:%s/\(\text.\{-}\)\{\}\\tabularnewline/\1{foo}\\tabularnewline
Is it possible to make my RE more specific in telling vim that I want
to do the replace only 5 times.
Thanks |

I'm new to vim scripting and this question got
me interested.
With the following script in my _vimrc file
function Change( count)
1
let i = 0
while i < a:count
s/c/X/
+
let i = i + 1
endwhile
endfunction
When executed with a :call Change(5)
the script changed the first occurance of "c"
to "X" on the first 5 lines.
However, if one of the lines does not contain a
"c", the script produces an error and only four
changes are made.
Question 1:
Is there a method of testing the substitute command?
Something like:
if( s/c/X/ == 0)
+
endif
Question 2:
Can the error message be supresed?
Question 3:
How can the script be located in another file
and then loaded and called when required?

Well, this can be replaced to 1,5s/c/X/. It's harder if you want to
replace at most 5 occurences per line, but I can't think of a solution
for that right now without creating a complicated script.

:h search()

:h s_flags and look for e

There are various ways to achieve this. You could use filetype
plugins, global plugins and autocommands. There are probably more
ways, I can't think of right now.
See :h filetype-plugin
:h add-global-plugin
:h autocommand
