nvim-spectre

A search panel for neovim.

Spectre find the enemy and replace them with dark power.

demo

Why Use Spectre?

  • Use regex in search
  • It can filter search by path glob (filetype)
  • It only searches when you leave Insert Mode
  • Use one buffer and you can edit or move
  • A tool to replace text on project

Installation

Plug 'nvim-lua/plenary.nvim'
Plug 'nvim-pack/nvim-spectre'

You may also need to install the following:

MacOs

You may need run brew install gnu-sed.

Usage

vim.keymap.set('n', '<leader>S', '<cmd>lua require("spectre").toggle()<CR>', {
    desc = "Toggle Spectre"
})
vim.keymap.set('n', '<leader>sw', '<cmd>lua require("spectre").open_visual({select_word=true})<CR>', {
    desc = "Search current word"
})
vim.keymap.set('v', '<leader>sw', '<esc><cmd>lua require("spectre").open_visual()<CR>', {
    desc = "Search current word"
})
vim.keymap.set('n', '<leader>sp', '<cmd>lua require("spectre").open_file_search({select_word=true})<CR>', {
    desc = "Search on current file"
})

Use command: :Spectre

Warnings

  • Always commit your files before you replace text. nvim-spectre does not support undo directly.
  • Don't use your crazy vim skills to edit result text or UI or you may encounter strange behaviour.
  • You can use dd to toggle result items.
  • You need to use <Esc> not <C-c> to leave insert mode.

Regex Issues

  • The default regex uses vim's magic mode \v and no-ignore-case.
  • It has different regex syntax compared to the rg command and replace command sed so be careful when replacing text.
  • It has a different highlighting result because I use vim regex to highlight text so be careful but you can try to replace.
  • If possible, we recommend building and using rust oxi engine to replace.

Replace

You can replace groups with \0-9 similar to vim and sed, if you run a replace command and don't see the change you may need to reload file with :e because sed is replace outside vim.

})

Custom Functions

-- if you want to get items from spectre panel you can use some of the
-- following functions to get data from spectre.
require('spectre.actions').get_current_entry()
require('spectre.actions').get_all_entries()
require('spectre.actions').get_state()

-- write your custom open function
require('spectre').open({
  is_insert_mode = true,
  -- the directory where the search tool will be started in
  cwd = "~/.config/nvim",
  search_text="test",
  replace_text="test",
  -- the pattern of files to consider for searching
  path="lua/**/*.lua",
  -- the directories or files to search in
  search_paths = {"lua/", "plugin/"},
  is_close = false, -- close an exists instance of spectre and open new
})
-- you can use all variables above on command line
-- for example: Spectre % is_insert_mode=true cwd=~/.config/nvim
-- in this example `%` will expand to current file.

Search paths

By default, searching is performed in the current working directory, which can also be customized using the cwd option in the example above.

The path option limits the search only to the files matching the provided pattern. Note, however, that even if you provide the path, all files in the cwd still need to be listed, and this could be quite slow if cwd is a large directory.

To limit the search paths further, you can also provide the search_paths option. This is the list of directories or files to search in, regardless of the cwd.

Replace Method

There are three replace methods sed, oxi and sd.

Sed oxi
group number by '\0' group number by '${0}'
use vim to highlight on UI use rust to highlight on UI
use sed to replace use rust to replace
run sed command call rust code directly by nvim-oxi

Install oxi:

  • you will need to install cargo and run the command: build.sh nvim-oxi

  • set default replace command to "oxi" on setup()

require('spectre').setup({
    default = {
        replace = {
            cmd = "oxi"
       }
    }
  )

FAQ

  • How can I add a custom status line? windline
    require('windline').add_status(
        require('spectre.state_utils').status_line()
    )
  • How to avoid ui break?
require('spectre').setup({ is_block_ui_break = true })

Spectre hardcodes some mappings in order to work correctly. You can remap them as described above. You are allowed to create as many mappings as you want. For name and description choose any value. 'map' and 'cmd' are the only important fields.

  • Is spectre compatible with the plugin mini.animate?

Yes, but only if you set opts = { open = { enable = false } } on mini.animate, otherwise it will cause serious issues preventing spectre from opening/closing.

  • Why is it called Spectre?

I wanted to call it Search Panel but this name is not cool. I got the name of a hero on a game. Spectre has a skill to find enemy on global map so I use it:)
