Serpl

serpl is a terminal user interface (TUI) application that allows users to search and replace keywords in an entire folder, similar to the functionality available in VS Code.

https://github.com/yassinebridi/serpl/assets/18403595/348506704-73336074-bfaf-4a9a-849c-bd4aa4e24afc

Features

Search for keywords across an entire project folder, with options for case sensitivity, AST Grep and more.
Replace keywords with options for preserving case, AST Grep and more.
Interactive preview of search results.
Keyboard navigation for efficient workflow.
Configurable key bindings and search modes.

Installation and Update

Prerequisites

ripgrep installed on your system.
(Optional) ast-grep installed on your system, if you want to use the AST Grep functionality.

Steps

Install the application using Cargo:

cargo install serpl

- If you want to install the application with the AST Grep functionality, you can use the following command:

cargo install serpl --features ast_grep

Run the application:

serpl

Binaries

Check the releases page for the latest binaries.

OS Specific Installation

Brew

serpl can be installed using Homebrew:

brew install serpl

Arch Linux

serpl can be installed from the official repositories using pacman:

pacman -S serpl

Nix/NixOS

serpl is included in nixpkgs since 24.11, and can be installed via Nix in different ways:

On standalone Nix setups:

nix profile install nixpkgs#serpl

On NixOS (via configuration.nix or similar):

{pkgs, ...}: {
  environment.systemPackages = [pkgs.serpl];
}

On Home-Manager:

{pkgs, ...}: {
  home.packages = [pkgs.serpl];
}

Usage

Basic Commands

Start the application in the current directory:

serpl

Start the application and provide the project root path:

serpl --project-root /path/to/project

Key Bindings

Default key bindings can be customized through the config.json file.

Default Key Bindings

| Key Combination | Action | | ---------------------------- | ----------------------------------------- | | Ctrl + c | Quit | | Ctrl + d | Quit | | Ctrl + b | Help | | Tab | Switch between tabs | | Backtab | Switch to previous tabs | | Ctrl + o | Process replace for all files | | r | Process replace for selected file or line | | Ctrl + n | Toggle search and replace modes | | Enter | Execute search (for large folders) | | g / Left / h | Go to top of the list | | G / Right / l | Go to bottom of the list | | j / Down | Move to the next item | | k / Up | Move to the previous item | | / | Search results list | | d | Delete selected file or line | | Esc | Exit the current pane or dialog | | Enter (in dialogs) / y | Confirm action | | Esc (in dialogs) / n | Cancel action | | h, l, Tab (in dialogs) | Navigate dialog options |

Configuration

serpl uses a configuration file to manage key bindings and other settings. By default, the path to the configuration file can be found by running serpl --version. You can use various file formats for the configuration, such as JSON, JSON5, YAML, TOML, or INI.

Example Configurations

JSON

{   "keybindings": {     "<Ctrl-d>": "Quit",     "<Ctrl-c>": "Quit",     "<Tab>": "LoopOverTabs",     "<Backtab>": "BackLoopOverTabs",     "<Ctrl-o>": "ProcessReplace",     "<Ctrl-b>": "ShowHelp"   } }

JSON5

{   keybindings: {     "<Ctrl-d>": "Quit",     "<Ctrl-c>": "Quit",     "<Tab>": "LoopOverTabs",     "<Backtab>": "BackLoopOverTabs",     "<Ctrl-o>": "ProcessReplace",     "<Ctrl-b>": "ShowHelp",   }, }

YAML

keybindings:   "<Ctrl-d>": "Quit"   "<Ctrl-c>": "Quit"   "<Tab>": "LoopOverTabs"   "<Backtab>": "BackLoopOverTabs"   "<Ctrl-o>": "ProcessReplace"   "<Ctrl-b>": "ShowHelp"

TOML

[keybindings] "<Ctrl-d>" = "Quit" "<Ctrl-c>" = "Quit" "<Tab>" = "LoopOverTabs" "<Backtab>" = "BackLoopOverTabs" "<Ctrl-o>" = "ProcessReplace" "<Ctrl-b>" = "ShowHelp"

INI

[keybindings] <Ctrl-d> = Quit <Ctrl-c> = Quit <Tab> = LoopOverTabs <Backtab> = BackLoopOverTabs <Ctrl-o> = ProcessReplace <Ctrl-b> = ShowHelp

You can customize the key bindings by modifying the configuration file in the format of your choice.

Panes

Search Input

Input field for entering search keywords.
Toggle search modes (Simple, Match Case, Match Whole Word, Match Case Whole Word, Regex, AST Grep).

- Simple: Search all occurrences of the keyword. - Match Case: Search occurrences with the same case as the keyword. - Match Whole Word: Search occurrences that match the keyword exactly. - Match Case Whole Word: Search occurrences that match the keyword exactly with the same case. - Regex: Search occurrences using a regular expression. - AST Grep: Search occurrences using AST Grep.

[!TIP]

If current directory is considerebly large, you have to click Enter to start the search.

Replace Input

Input field for entering replacement text.
Toggle replace modes (Simple, Preserve Case, AST Grep).

- Simple: Replace all occurrences of the keyword. - Preserve Case: Replace occurrences while preserving the case of the keyword. - AST Grep: Replace occurrences using AST Grep.

Search Results Pane

List of files with search results.
Navigation to select and view files.
Option to delete files from the search results.
Search results count and current file count.
Ability to search the list using the / key.

Preview Pane

Display of the selected file with highlighted search results, and context.
Navigation to view different matches within the file.
Option to delete individual lines containing matches.

Quick Hints

Use the Ctrl + b key combination to display the help dialog.
Use the Ctrl + o key combination to process the replace for all files.
Use the r key to process the replace for the selected file or line.
Use the Ctrl + n key combination to toggle between search and replace modes.
Use the g, G, j, and k keys to navigate through the search results.
Use the d key to delete the selected file or line.

Neovim Integration using toggleterm

Check out the toggleterm.nvim plugin for Neovim, which provides a terminal that can be toggled with a key binding. Or you can use the following configuration, if you are using AstroNvim:

return {
  "akinsho/toggleterm.nvim",
  cmd = { "ToggleTerm", "TermExec" },
  dependencies = {
    {
      "AstroNvim/astrocore",
      opts = function(_, opts)
        local maps = opts.mappings
        local astro = require "astrocore"
        maps.n["<Leader>t"] = vim.tblget(opts, "map_sections", "t")
local serpl = {           callback = function()             astro.toggletermcmd "serpl"           end,           desc = "ToggleTerm serpl",         }         maps.n["<Leader>sr"] = { serpl.callback, desc = serpl.desc }
maps.n["<Leader>tf"] = { "<Cmd>ToggleTerm direction=float<CR>", desc = "ToggleTerm float" }         maps.n["<Leader>th"] = { "<Cmd>ToggleTerm size=10 direction=horizontal<CR>", desc = "ToggleTerm horizontal split" }         maps.n["<Leader>tv"] = { "<Cmd>ToggleTerm size=80 direction=vertical<CR>", desc = "ToggleTerm vertical split" }         maps.n["<F7>"] = { '<Cmd>execute v:count . "ToggleTerm"<CR>', desc = "Toggle terminal" }         maps.t["<F7>"] = { "<Cmd>ToggleTerm<CR>", desc = "Toggle terminal" }         maps.i["<F7>"] = { "<Esc><Cmd>ToggleTerm<CR>", desc = "Toggle terminal" }         maps.n["<C-'>"] = { '<Cmd>execute v:count . "ToggleTerm"<CR>', desc = "Toggle terminal" }         maps.t["<C-'>"] = { "<Cmd>ToggleTerm<CR>", desc = "Toggle terminal" }         maps.i["<C-'>"] = { "<Esc><Cmd>ToggleTerm<CR>", desc = "Toggle terminal" }       end,     },   },   opts = {     highlights = {       Normal = { link = "Normal" },       NormalNC = { link = "NormalNC" },       NormalFloat = { link = "NormalFloat" },       FloatBorder = { link = "FloatBorder" },       StatusLine = { link = "StatusLine" },       StatusLineNC = { link = "StatusLineNC" },       WinBar = { link = "WinBar" },       WinBarNC = { link = "WinBarNC" },     },     size = 10,     ---@param t Terminal     on_create = function(t)       vim.opt_local.foldcolumn = "0"       vim.opt_local.signcolumn = "no"       if t.hidden then         local toggle = function() t:toggle() end         vim.keymap.set({ "n", "t", "i" }, "<C-'>", toggle, { desc = "Toggle terminal", buffer = t.bufnr })         vim.keymap.set({ "n", "t", "i" }, "<F7>", toggle, { desc = "Toggle terminal", buffer = t.bufnr })       end     end,     shading_factor = 2,     direction = "float",     float_opts = { border = "rounded" },   }, }

Helix integration

You can add a keybinding like the following to open Serpl inside Helix:

[keys.normal.ret]
t = [":write-all", ":insert-output serpl >/dev/tty", ":redraw", ":reload-all"]
