TIL: highlight search matches in Vim
Like any good text editor, Vim supports highlighting of search matches. Think of it like searching in your browser: it highlights all occurrences of the search string. In Vim it’s similar, except that it also works with regular expressions.
Highlighting of matches is turned off by default. Enable it with the following
snippet in your
" Highlight search matches set hlsearch
The following makes the whole thing a little smarter when it comes to matching upper case and lower case:
" Ignore case when searching set ignorecase " except when search string contains uppercase set smartcase
Notice that there is still a difference between searching in Vim and in your browser: the latter jumps to the first match while you enter the search string. If that’s your cup of tea, enable it with:
" Jump to first match while entering search string set incsearch
Here’s a handy shortcut to turn highlighting off once you’re done with
searching. It’s the proper way to do that, instead of searching for something
asdf as I used to do when I started out with Vim many years
ago. Note that highlighting will turn itself back on next time you search.
" Turn highlighting off till next search map <silent> <leader>/ :nohlsearch<cr>
<leader> key following by a slash. As the mnemonic counterpart to
the single slash used to initiate a search.
By default the leader key is set to backslash, but I have mine set to the easier-to-reach comma instead:
" Set leader key let mapleader = ","
Existing mappings are not updated after setting this value. Some plugins set mappings as well. So make sure to set the leader early enough in your config.
