+ | With this tip, you can select some text, then press a key to search for the next occurrence of the text. Two alternative methods are presented. |
||
− | With the following, you can use <tt>*</tt> (or <tt>#</tt>) to search forwards (or backwards) for the current visual selection from either characterwise visual mode or linewise visual mode (but not from blockwise visual mode). These visual searches behave like any other searches; the 'n' and 'N' commands work as they should, and the search history correctly records each search. This solution works for all characters, and even for searches that span multiple lines (that is, if you select "a" at the end of one line and "b" at the beginning of the next, we'll only find other lines that end in "a" and have "b" as the first character on the next line). |

+ | <code>gvy</code> reselects then yanks the visual selection (copy to <code>@"</code>). |
||
+ | |||
+ | <code>/<C-R><C-R>=</code> starts a search, then substitutes the expression register (<code>@=</code>) literally {{help|c_CTRL-R_CTRL-R}}. The result of the following expression is inserted into the command line. |
||
+ | |||
+ | <code>escape()</code> inserts a backslash before each <code>/\.*$^~[</code> character found in <code>@"</code>. The <code>/</code> must be escaped because we are using a <code>/</code> command. The other characters need to be escaped because they have a special meaning in a regular expression. |
||
+ | |||
+ | <code>substitute()</code> replaces every sequence of one or more whitespace characters (space, tab, newline) with an escaped regular expression that will search for any similar sequence. |
||
+ | |||
+ | <code>gV</code> allows the mappings to work in <code>--SELECT--</code> mode as well as <code>--VISUAL--</code>. Without <code>gV</code>, searching for text in select mode would not move the cursor because the selection is automatically reselected after the mapping. |
||
+ | |||
+ | |||
+ | ==Paste matching text of last search== |
||
+ | When using <code>^r/</code> in INSERT mode what one most of the time wants is to paste the matched text not the regex used to search the text. Example: after using * on a word, <code>^r/</code> will paste the word with <code>\<</code> prepended and <code>\></code> appended, not what we want. Similarly after a visual search we don't want the <code>\V</code> prepended. The following map takes care of these issues: |
||
+ | <source lang="vim"> |
||
+ | function! Del_word_delims() |
||
+ | let reg = getreg('/') |
||
+ | " After * i^r/ will give me pattern instead of \<pattern\> |
||
+ | let res = substitute(reg, '^\\<\(.*\)\\>$', '\1', '' ) |
||
+ | if res != reg |
||
+ | return res |
||
+ | endif |
||
+ | " After * on a selection i^r/ will give me pattern instead of \Vpattern |
||
+ | let res = substitute(reg, '^\\V' , '' , '' ) |
||
+ | let res = substitute(res, '\\\\' , '\\', 'g') |
||
+ | let res = substitute(res, '\\n' , '\n', 'g') |
||
+ | return res |
||

||
+ | cnoremap <c-r>/ <c-r>=Del_word_delims()<cr> |
||
+ | </source> |
||
+ | |||
+ | For more complicated patterns, it's better to act on the text matched with the last search, using the {{help|prefix=no|gn}} object. |
||
+ | |||
+ | So, you could also accomplish insertion of a search match using <code>maygn`ap</code> in normal mode. I.e. <code>ma</code> to drop a mark to return to later, <code>y</code> to yank the <code>gn</code> object, then <code>`a</code> to jump back where you were (because the yank will leave you on the text copied), finally <code>p</code> to paste. |
||
+ | |||
+ | When starting from insert mode, you don't even need a mark: you can use the <code>gi</code> command to start again from where you left off. For example: |
||
+ | |||
+ | <pre> |
||
+ | :inoremap <F3> <Esc>ygngi<C-R>0 |
||
+ | </pre> |
||
+ | |||
+ | Here, <code>ygn</code> is as before, but <code>gi</code> is used to go back to insert mode in the same place you left off, then <code><C-R>0</code> inserts the copied text. |

With this tip, you can select some text, then press a key to search for the next occurrence of the text. Two alternative methods are presented.
Simple
The simplest solution is:
vnorem // y/<c-r>"<cr>
Advanced
The following is a more advanced implementation, with more robust functionality than the above keymap.
Features
- Press
*
to search forwards for selected text, or#
to search backwards. - As normal, press
n
for next search, orN
for previous. - Handles multiline selection and search.
- Whitespace in the selection matches any whitespace when searching (searching for "hello world" will also find "hello" at the end of a line, with "world" at the start of the next line).
- Each search is placed in the search history allowing you to easily repeat previous searches.
- No registers are changed.
Place the following mappings in your vimrc:
" Search for selected text, forwards or backwards. vnoremap <silent> * :<C-U> \let old_reg=getreg('"')<Bar>let old_regtype=getregtype('"')<CR> \gvy/<C-R><C-R>=substitute( \escape(@", '/\.*$^~['), '\_s\+', '\\_s\\+', 'g')<CR><CR> \gV:call setreg('"', old_reg, old_regtype)<CR> vnoremap <silent> # :<C-U> \let old_reg=getreg('"')<Bar>let old_regtype=getregtype('"')<CR> \gvy?<C-R><C-R>=substitute( \escape(@", '?\.*$^~['), '\_s\+', '\\_s\\+', 'g')<CR><CR> \gV:call setreg('"', old_reg, old_regtype)<CR>
Following is an alternative version with some extra features:
- A global variable (
g:VeryLiteral
) controls whether selected whitespace matches any whitespace (by default, VeryLiteral is off, so any whitespace is found). - Type
\vl
to toggle VeryLiteral to turn whitespace matching off/on (assuming the default backslash leader key). - When VeryLiteral is off, any selected leading or trailing whitespace will not match newlines, which is more convenient, and avoids false search hits.
Create file (for example) ~/.vim/plugin/vsearch.vim
(Unix) or $HOME/vimfiles/plugin/vsearch.vim
(Windows) with contents:
" Search for selected text. " http://vim.wikia.com/wiki/VimTip171 let s:save_cpo = &cpo | set cpo&vim if !exists('g:VeryLiteral') let g:VeryLiteral = 0 endif function! s:VSetSearch(cmd) let old_reg = getreg('"') let old_regtype = getregtype('"') normal! gvy if @@ =~?

(g:VeryLiteral ? "On" : "Off")<CR> if !hasmapto("<Plug>VLToggle") nmap <unique> <Leader>vl <Plug>VLToggle endif let &cpo = s:save_cpo | unlet s:save_cpo
Explanation
The first suggested mapping was:
vnoremap <silent> * :<C-U> \let old_reg=getreg('"')<Bar>let old_regtype=getregtype('"')<CR> \gvy/<C-R><C-R>=substitute( \escape(@", '/\.*$^~['), '\_s\+', '\\_s\\+', 'g')<CR><CR> \gV:call setreg('"', old_reg, old_regtype)<CR>
When in visual mode, pressing *
will then perform these commands:
:<C-U> let old_reg=getreg('"')<Bar>let old_regtype=getregtype('"')<CR> gvy /<C-R><C-R>= substitute( escape(@", '/\.*$^~['), '\_s\+', '\\_s\\+', 'g')<CR><CR> gV :call setreg('"', old_reg, old_regtype)<CR>
:<C-U>
enters command mode and deletes (Ctrl-u) the '<,'>
range automatically inserted due to the visual selection. The unnamed register (@"
) is saved and later restored.
gvy
reselects then yanks the visual selection (copy to @"
).
/<C-R><C-R>=
starts a search, then substitutes the expression register (@=
) literally :help c_CTRL-R_CTRL-R. The result of the following expression is inserted into the command line.
escape()
inserts a backslash before each /\.*$^~[
character found in @"
. The /
must be escaped because we are using a /
command. The other characters need to be escaped because they have a special meaning in a regular expression.
substitute()
replaces every sequence of one or more whitespace characters (space, tab, newline) with an escaped regular expression that will search for any similar sequence.
gV
allows the mappings to work in --SELECT--
mode as well as --VISUAL--
. Without gV
, searching for text in select mode would not move the cursor because the selection is automatically reselected after the mapping.
Paste matching text of last search
When using ^r/
in INSERT mode what one most of the time wants is to paste the matched text not the regex used to search the text. Example: after using * on a word, ^r/
will paste the word with \<
prepended and \>
appended, not what we want. Similarly after a visual search we don't want the \V
prepended. The following map takes care of these issues:
function! Del_word_delims()
let reg = getreg('/')
" After * i^r/ will give me pattern instead of \<pattern\>
let res = substitute(reg, '^\\<\(.*\)\\>$', '\1', '' )
if res != reg
return res
endif
" After * on a selection i^r/ will give me pattern instead of \Vpattern
let res = substitute(reg, '^\\V' , '' , '' )
let res = substitute(res, '\\\\' , '\\', 'g')
let res = substitute(res, '\\n' , '\n', 'g')
return res
endfunction
inoremap <silent> <c-r>/ <c-r>=Del_word_delims()<cr>
cnoremap <c-r>/ <c-r>=Del_word_delims()<cr>
For more complicated patterns, it's better to act on the text matched with the last search, using the gn object.
So, you could also accomplish insertion of a search match using maygn`ap
in normal mode. I.e. ma
to drop a mark to return to later, y
to yank the gn
object, then `a
to jump back where you were (because the yank will leave you on the text copied), finally p
to paste.
When starting from insert mode, you don't even need a mark: you can use the gi
command to start again from where you left off. For example:
:inoremap <F3> <Esc>ygngi<C-R>0
Here, ygn
is as before, but gi
is used to go back to insert mode in the same place you left off, then <C-R>0
inserts the copied text.

TO DO
Tips related to visual searching (need to merge):
This mapping forms a substitute command with the selected text:
vnoremap <C-r> "hy:%s/<C-r>h//gc<left><left><left>
Found on Stack Overflow: Vim replace selected text.
To auto escape certain characters (e.g. slash and backslash), one can use:
vnoremap <C-h> ""y:%s/<C-R>=escape(@", '/\')<CR>//g<Left><Left>
