# `@actions/core`
> Core functions for setting results, logging, registering secrets and exporting variables across actions
## Usage
### Import the package
```js
// javascript
const core = require('@actions/core');
// typescript
import * as core from '@actions/core';
```
#### Inputs/Outputs
Action inputs can be read with `getInput`. Outputs can be set with `setOutput` which makes them available to be mapped into inputs of other actions to ensure they are decoupled.
```js
const myInput = core.getInput('inputName', { required: true });
core.setOutput('outputKey', 'outputVal');
```
#### Exporting variables
Since each step runs in a separate process, you can use `exportVariable` to add it to this step and future steps environment blocks.
```js
core.exportVariable('envVar', 'Val');
```
#### Setting a secret
Setting a secret registers the secret with the runner to ensure it is masked in logs.
```js
core.setSecret('myPassword');
```
#### PATH Manipulation
To make a tool's path available in the path for the remainder of the job (without altering the machine or containers state), use `addPath`. The runner will prepend the path given to the jobs PATH.
```js
core.addPath('/path/to/mytool');
```
#### Exit codes
You should use this library to set the failing exit code for your action. If status is not set and the script runs to completion, that will lead to a success.
```js
const core = require('@actions/core');
try {
// Do stuff
}
catch (err) {
// setFailed logs the message and sets a failing exit code
core.setFailed(`Action failed with error ${err}`);
}
Note that `setNeutral` is not yet implemented in actions V2 but equivalent functionality is being planned.
```
#### Logging
Finally, this library provides some utilities for logging. Note that debug logging is hidden from the logs by default. This behavior can be toggled by enabling the [Step Debug Logs](../../docs/action-debugging.md#step-debug-logs).
```js
const core = require('@actions/core');
const myInput = core.getInput('input');
try {
core.debug('Inside try block');
if (!myInput) {
core.warning('myInput was not set');
}
// Do stuff
}
catch (err) {
core.error(`Error ${err}, action may still succeed though`);
}
```
This library can also wrap chunks of output in foldable groups.
```js
const core = require('@actions/core')
// Manually wrap output
core.startGroup('Do some function')
doSomeFunction()
core.endGroup()
// Wrap an asynchronous function call
const result = await core.group('Do something async', async () => {
const response = await doSomeHTTPRequest()
return response
})
```
#### Action state
You can use this library to save state and get state for sharing information between a given wrapper action:
**action.yml**
```yaml
name: 'Wrapper action sample'
inputs:
name:
default: 'GitHub'
runs:
using: 'node12'
main: 'main.js'
post: 'cleanup.js'
```
In action's `main.js`:
```js
const core = require('@actions/core');
core.saveState("pidToKill", 12345);
```
In action's `cleanup.js`:
```js
const core = require('@actions/core');
var pid = core.getState("pidToKill");
process.kill(pid);
```

## v3.0.0 2017-01-31
- Initial version of Nodemailer 3
This update brings a lot of breaking changes:
- License changed from MIT to **EUPL-1.1**. This was possible as the new version of Nodemailer is a major rewrite. The features I don't have ownership for, were removed or reimplemented. If there's still some snippets in the code that have vague ownership then notify <mailto:andris@kreata.ee> about the conflicting code and I'll fix it.
- Requires **Node.js v6+**
- All **templating is gone**. It was too confusing to use and to be really universal a huge list of different renderers would be required. Nodemailer is about email, not about parsing different template syntaxes
- **No NTLM authentication**. It was too difficult to re-implement. If you still need it then it would be possible to introduce a pluggable SASL interface where you could load the NTLM module in your own code and pass it to Nodemailer. Currently this is not possible.
- **OAuth2 authentication** is built in and has a different [configuration](https://nodemailer.com/smtp/oauth2/). You can use both user (3LO) and service (2LO) accounts to generate access tokens from Nodemailer. Additionally there's a new feature to authenticate differently for every message – useful if your application sends on behalf of different users instead of a single sender.
- **Improved Calendaring**. Provide an ical file to Nodemailer to send out [calendar events](https://nodemailer.com/message/calendar-events/).
And also some non-breaking changes:
- All **dependencies were dropped**. There is exactly 0 dependencies needed to use Nodemailer. This brings the installation time of Nodemailer from NPM down to less than 2 seconds
- **Delivery status notifications** added to Nodemailer
- Improved and built-in **DKIM** signing of messages. Previously you needed an external module for this and it did quite a lousy job with larger messages
- **Stream transport** to return a RFC822 formatted message as a stream. Useful if you want to use Nodemailer as a preprocessor and not for actual delivery.
- **Sendmail** transport built-in, no need for external transport plugin
See [Nodemailer.com](https://nodemailer.com/) for full documentation
## 2.7.0 2016-12-08
- Bumped mailcomposer that generates encoded-words differently which might break some tests
## 2.6.0 2016-09-05
- Added new options disableFileAccess and disableUrlAccess
- Fixed envelope handling where cc/bcc fields were ignored in the envelope object
## 2.4.2 2016-05-25
- Removed shrinkwrap file. Seemed to cause more trouble than help
## 2.4.1 2016-05-12
- Fixed outdated shrinkwrap file
## 2.4.0 2016-05-11
- Bumped mailcomposer module to allow using `false` as attachment filename (suppresses filename usage)
- Added NTLM authentication support
## 2.3.2 2016-04-11
- Bumped smtp transport modules to get newest smtp-connection that fixes SMTPUTF8 support for internationalized email addresses
## 2.3.1 2016-04-08
- Bumped mailcomposer to have better support for message/822 attachments
## 2.3.0 2016-03-03
- Fixed a bug with attachment filename that contains mixed unicode and dashes
- Added built-in support for proxies by providing a new SMTP option `proxy` that takes a proxy configuration url as its value
- Added option `transport` to dynamically load transport plugins
- Do not require globally installed grunt-cli
## 2.2.1 2016-02-20
- Fixed a bug in SMTP requireTLS option that was broken
## 2.2.0 2016-02-18
- Removed the need to use `clone` dependency
- Added new method `verify` to check SMTP configuration
- Direct transport uses STARTTLS by default, fallbacks to plaintext if STARTTLS fails
- Added new message option `list` for setting List-\* headers
- Add simple proxy support with `getSocket` method
- Added new message option `textEncoding`. If `textEncoding` is not set then detect best encoding automatically
- Added new message option `icalEvent` to embed iCalendar events. Example [here](examples/ical-event.js)
- Added new attachment option `raw` to use prepared MIME contents instead of generating a new one. This might be useful when you want to handcraft some parts of the message yourself, for example if you want to inject a PGP encrypted message as the contents of a MIME node
- Added new message option `raw` to use an existing MIME message instead of generating a new one
## 2.1.0 2016-02-01
Republishing 2.1.0-rc.1 as stable. To recap, here's the notable changes between v2.0 and v2.1:

# Contribute
## Introduction
First, thank you for considering contributing to nodemailer! It's people like you that make the open source community such a great community! 😊
We welcome any type of contribution, not only code. You can help with
- **QA**: file bug reports, the more details you can give the better (e.g. screenshots with the console open)
- **Marketing**: writing blog posts, howto's, printing stickers, ...
- **Community**: presenting the project at meetups, organizing a dedicated meetup for the local community, ...
- **Code**: take a look at the [open issues](https://github.com/nodemailer/nodemailer/issues). Even if you can't write code, commenting on them, showing that you care about a given issue matters. It helps us triage them.
- **Money**: we welcome financial contributions in full transparency on our [open collective](https://opencollective.com/nodemailer).
## Your First Contribution
Working on your first Pull Request? You can learn how from this *free* series, [How to Contribute to an Open Source Project on GitHub](https://egghead.io/series/how-to-contribute-to-an-open-source-project-on-github).
## Submitting code
Any code change should be submitted as a pull request. The description should explain what the code does and give steps to execute it. The pull request should also contain tests.
## Code review process
The bigger the pull request, the longer it will take to review and merge. Try to break down large pull requests in smaller chunks that are easier to review and merge.
It is also always helpful to have some context for your pull request. What was the purpose? Why does it matter to you?
## Financial contributions
We also welcome financial contributions in full transparency on our [open collective](https://opencollective.com/nodemailer).
Anyone can file an expense. If the expense makes sense for the development of the community, it will be "merged" in the ledger of our open collective by the core contributors and the person who filed the expense will be reimbursed.
## Questions
If you have any questions, create an [issue](https://github.com/nodemailer/nodemailer/issues) (protip: do a quick search first to see if someone else didn't ask the same question before!).
You can also reach us at hello@nodemailer.opencollective.com.

# Nodemailer
[![Nodemailer](https://raw.githubusercontent.com/nodemailer/nodemailer/master/assets/nm_logo_200x136.png)](https://nodemailer.com/about/)
Send e-mails from Node.js – easy as cake! 🍰✉️
[![NPM](https://nodei.co/npm/nodemailer.png?downloads=true&downloadRank=true&stars=true)](https://nodemailer.com/about/)
See [nodemailer.com](https://nodemailer.com/) for documentation and terms.
## Having an issue?
#### First review the docs
Documentation for Nodemailer can be found at [nodemailer.com](https://nodemailer.com/about/).
#### Nodemailer throws a SyntaxError for "..."
You are using older Node.js version than v6.0. Upgrade Node.js to get support for the spread operator.
#### I'm having issues with Gmail
Gmail either works well or it does not work at all. It is probably easier to switch to an alternative service instead of fixing issues with Gmail. If Gmail does not work for you then don't use it. Read more about it [here](https://nodemailer.com/usage/using-gmail/).
#### I get ETIMEDOUT errors
Check your firewall settings. Timeout usually occurs when you try to open a connection to a port that is firewalled either on the server or on your machine.
#### I get TLS errors
* If you are running the code in your own machine, then check your antivirus settings. Antiviruses often mess around with email ports usage. Node.js might not recognize the MITM cert your antivirus is using.
* Latest Node versions allow only TLS versions 1.2 and higher, some servers might still use TLS 1.1 or lower. Check Node.js docs how to get correct TLS support for your app.
#### I have a different problem
If you are having issues with Nodemailer, then the best way to find help would be [Stack Overflow](https://stackoverflow.com/search?q=nodemailer) or revisit the [docs](https://nodemailer.com/about/).
