ripgrep-node

ripgrep-node is a node js interface for ripgrep.
It is written in TypeScript and is built on ripgrep version 11.0.1

For complete usage and details, refer to the docs at

Install

Use npm to install
``
npm install ripgrep-node
`

Requirements

ripgrep-node leverages the system ripgrep to run its commands. So either the standalone binary, rg in $PATH or a path to ripgrep needs to be provided in the constructor.

Usage

Ripgrep is a simple module that allows chaining ripgrep options on top of each other and get the result back. There is a couple of helper methods included to help in parsing, such as the as_dict module which shows all valid matches as a dictionary object.

To instantiate the class, use:
`
const {RipGrep} = require('ripgrep-node')
// The RipGrep class takes two arguments. The regex to search for and the folder path to search in
// A third argument can be provided if ripgrep is not install in $PATH

let rg = new RipGrep('he[l]{2}o', '/some/path/to/files')
`

The syntax for ripgrep-node is simliar to that of ripgrep itself.
`
rg.with_filename().line_number()...run().as_string()
// or
rg.options...run().asObject() // get an object of matches back
`
The above is eqivalent to running
`
rg --with-filename --line-number "he[l]{2}o" /path/to/some/files
`
Important run() should always be the last method that is being run followed by one of the output methods. If ripgrep options are placed after run, they will not be part of the command being executed. The docs are obtained from ripgreps man pages itself.

#### Output methods
Output can be obtained using the following three methods
- as_dict
- as_json
- as_string

Not all ripgrep output is compitable with as_dict and as_json` output formats
