Features

  • Interactive grep (for streaming)
    • sig allows users to interactively search through (streaming) data, updating results in real-time.
  • Archived mode
    • In Archived mode, since there is no seeking capability for streaming data received through a pipe, it is not possible to search backwards without exiting the process. Therefore, in sig, the latest N entries of streaming data are saved, and it is possible to switch to a mode where you can grep through these N entries based on key inputs at any given moment.
    • Additionally, by starting in this mode, it is also possible to grep through static data such as files.

Installation

Homebrew

brew install ynqa/tap/sigrs

Cargo

cargo install sigrs

Nix (flakes)

Add it as an input to your flake:

inputs = {
  sig.url = 'github:ynqa/sig/<optional-ref>'
}

Create a shell with it:

nix shell github:ynqa/sig

Or run it directly:

cat README.md | nix run github:ynqa/sig -- --archived

Nix (classic)

Fetch the source and use it, e.g. in your shell:

let
  pkgs = import <nixpkgs> {};

  sig = pkgs.callPackage (pkgs.fetchFromGitHub {
    owner = "ynqa";
    repo = "sig";
    rev = "v0.1.0";
    hash = "sha256-KHXBeQFmuA3YO9AN5dkY/fl/z2RdbR6AqSSEGUNrxt4=";
  }) {};
in
  pkgs.mkShell {
    packages = [sig];
  }
