Description

Code-suggester automates the steps involved in making code changes or code suggestions to your GitHub repository! Code-suggester
1. can be imported as a library, or
2. used as a CLI tool, or
3. configured in a GitHub Action

Core Library

$3

``bash
npm i code-suggester
`

$3

`js
const suggester = require("code-suggester");

async function main() {
const octokit = new Octokit({ auth: process.env.ACCESS_TOKEN });
const changes =

'Bar-Owner',
)
}

`


$3

The reviewPullRequest() method creates a code suggestion review on a GitHub Pull request with the files given as input.
From these files, calculate the hunk diff and make all the multiline code suggestion review comments on a given pull request with these hunks given
that they are in scope of the pull request. Outof scope suggestions are not made.

In-scope suggestions are specifically: suggestions whose file is in-scope of the pull request,
and suggestions whose diff hunk is a subset of the pull request's files hunks.

If a file is too large to load in the review, it is skipped in the suggestion phase.

If the program terminates without exception, a timeline comment will be made with all errors or suggestions that could not be made.

review-pr:
runs-on: ubuntu-latest

request code, make sure that an external developer cannot override the commands run
from the pull request.

Supported Node.js Versions

Our client libraries follow the Node.js release schedule.
Libraries are compatible with all current _active_ and _maintenance_ versions of
Node.js.

Client libraries targeting some end-of-life versions of Node.js are available, and
can be installed via npm dist-tags.
The dist-tags follow the naming convention legacy-(version).

_Legacy Node.js versions are supported as a best effort:_

* Legacy versions will not be tested in continuous integration.
* Some security patches may not be able to be backported.
* Dependencies will not be kept up-to-date, and features will not be backported.

#### Legacy tags available

* legacy-8: install client libraries from this dist-tag for versions
compatible with Node.js 8.




Versioning

This library follows Semantic Versioning.


This library is considered to be in alpha. This means it is still a
work-in-progress and under active development. Any release is subject to
backwards-incompatible changes at any time.
