nvim-hlslens helps you better glance at matched information, seamlessly jump between matched instances.
hlslens-demo.mp4
- Fully customizable style of virtual text
- Clear highlighting and virtual text when cursor is out of range
- Display search result dynamically while cursor is moving
- Display search result for the current matched instance while searching
- Display search result for some built-in commands that support incsearch (need Neovim 0.8.0)
Need
vim.api.nvim_parse_cmdto parse built-in commands if incsearch is enabled.
Install nvim-hlslens with Packer.nvim:
use {'kevinhwang91/nvim-hlslens'}require('hlslens').setup()
local kopts = {noremap = true, silent = true}
vim.api.nvim_set_keymap('n', 'n',
[[<Cmd>execute('normal! ' . v:count1 . 'n')<CR><Cmd>lua require('hlslens').start()<CR>]],
kopts)
vim.api.nvim_set_keymap('n', 'N',
[[<Cmd>execute('normal! ' . v:count1 . 'N')<CR><Cmd>lua require('hlslens').start()<CR>]],
kopts)
vim.api.nvim_set_keymap('n', '*', [[*<Cmd>lua require('hlslens').start()<CR>]], kopts)
vim.api.nvim_set_keymap('n', '#', [[#<Cmd>lua require('hlslens').start()<CR>]], kopts)
vim.api.nvim_set_keymap('n', 'g*', [[g*<Cmd>lua require('hlslens').start()<CR>]], kopts)
vim.api.nvim_set_keymap('n', 'g#', [[g#<Cmd>lua require('hlslens').start()<CR>]], kopts)
vim.api.nvim_set_keymap('n', '<Leader>l', '<Cmd>noh<CR>', kopts)After using Minimal configuration:
Hlslens will add virtual text at the end of the line if the room is enough for virtual text, otherwise, add a floating window to overlay the statusline to display lens.
You can glance at the result provided by lens while searching when incsearch is on. Hlslens also
supports <C-g> and <C-t> to move to the next and previous match.
- Press
/or?to search text,/sand/eoffsets are supported; - Invoke API
require('hlslens').start();
- Run ex command
nohlsearch; - Map key to
:nohlsearch; - Invoke API
require('hlslens').stop();
