Re: S&R with search input from a file

Hi Ti,

I've removed the mapping that was misusing the default vim <C-R> behaviour.

I've reworked your code to the function below.

When I now do:

:call SRT_CorrectNames()

- I see my input list transformed to a joined line with \| between the words

- I see that I move to my file where I want to do substitution.
- I now get an error on the substitute

E486: pattern not found : \c\<\(<C-R>0\)\>

Any idea why pattern isn't found?

function! SRT_CorrectNames()
:sp input.txt    
:%s/$/\\|/        
:%j!             
":s/..$            
execute "normal! \<end>xx"

"0y$              
        let @0 = getline(1)
        di 0

"
:wincmd w        
%s/\c\<\(<C-R>0\)\>/\u&/g
"                   " substitute across the entire file (":%s/")
"                   " ignoring case ("\c")
"                   " a word must start here to match ("\<")
"                   " start the list of alternatives ("\(")
"                   " use control+R followed by zero
"                   "    to include the word-list joined by \|
"                   "    that we yanked previously
"                   " close the list of alternatives ("\)")
"                   " ensure that the word ends here ("\>")
"                   " and replace it with ("/")
"                   " the next letter uppercased ("\u")
"                   " the text we captured ("&")
"                   " and do all replacements on the line ("/g")
"
"This assumes that your input list is all just whole words, no funky
"regexp metachars (periods, backslashes, asterisks, or
"open-square-brackets come to mind).endfunction
endfunction

Hi Tim,

I'm trying to make a function out of your commands.
Perhaps that that is the reason why it's not working straight away.

This should work on all versions of vim, regardless of operating
system.  How are you determining that it isn't working?  Is it giving
you an error?  Is it not removing the last two characters (the "\|")
from the line?  If you are having a problem, you could tweak the
first couple steps to

  :1,$-s/$/\\|/

which will tack them onto every line *except* the last one, saving
you that ":s/..$/" step.

This sounds like you're trying to do this in some mode that isn't
normal-mode.  Perhaps command-mode?

You could yank the entire line and then just remove the newline at
the end if that's easier.

You mean...other than not remapping away something that is incredibly
valuable?  ;-)  You can always map something else to it:

  :cnoremap <f4> <c-r>
