nvim-spectre

A search panel for neovim.

Spectre find the enemy and replace them with dark power.

Why Use Spectre?

Use regex in search
It can filter search by path glob (filetype)
It only searches when you leave Insert Mode, incsearch can be annoying when writing regex
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:

BurntSushi/ripgrep (finder)
devicons (icons)
sed (replace tool)

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 sytax 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.

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.

Customization

require('spectre').setup()

Config

Change any settings if you don't like them. **Don't just copy all** as settings may change as the plugin is updated so it may be better use the default settings.

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,
  cwd = "~/.config/nvim",
  search_text="test",
  replace_text="test",
  path="lua/**/*.lua",
  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.

Replace Method

There are two replace methods sed and oxi.

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:)
