* **username** - the username for the account to publish with.
* **password** - the password for the account to publish with.
* **token** - the deploy token to publish with.
* **email** - the email address associated with the account to publish with.
* **registry** - the registry URL to use (https://registry.npmjs.org by default)
* **folder** - the folder, relative to the workspace, containing the library
(uses the workspace directory, by default)
* **always_auth** - forces npm to require authentication when accessing the
registry (false by default)
The following is a sample NPM configuration in your .drone.yml file which
can publish to the global npm registry:
The following secret values can be set to configure the plugin.
```yaml
publish:
npm:
username: $$NPM_USERNAME
password: $$NPM_PASSWORD
email: $$NPM_EMAIL
* **NPM_USERNAME** - corresponds to **username**.
* **NPM_PASSWORD** - corresponds to **password**.
* **NPM_TOKEN** - corresponds to **token**.
* **NPM_EMAIL** - corresponds to **email**.
* **NPM_REGISTRY** - corresponds to **registry**.
It is highly recommended to put the **NPM_PASSWORD** or **NPM_TOKEN** into
secrets. The other values are there for convenience when configuring multiple
repositories to use the same values. This can be done using the drone-cli.
```bash
drone secret add --image=npm \
octocat/hello-world NPM_PASSWORD abc123
```
For a private npm registry, such as
[Sinopia](https://github.com/rlidwka/sinopia) the following config can be used:
Then sign the YAML file after all secrets are added.
```bash
drone sign octocat/hello-world
```
See [secrets](http://readme.drone.io/0.5/usage/secrets/) for additional
information on secrets
## Authentication method
NPM registries typically authenticate based on a username password pair.
However NPM Enterprise users can also authenticate through
[tokens](http://blog.npmjs.org/post/106559223730/npm-enterprise-with-github-2fa).
If a token value is encountered the plugin will use that. If it is not present
then the plugin will default to username/password.
## Examples
Global NPM with **NPM_PASSWORD** as a secret.
```yaml
publish:
npm:
username: $$NPM_USERNAME
password: $$NPM_PASSWORD
email: $$NPM_EMAIL
registry: "http://myregistry:4873"
always_auth: true
npm:
username: bob
email: bob@bob.me
```
A private NPM registry, such as [Sinopia](https://github.com/rlidwka/sinopia)
with **NPM_PASSWORD** as a secret.
```yaml
npm:
username: drone
email: drone@drone.io
registry: "http://myregistry:4873"
```
[NPM Enterprise registry](https://www.npmjs.com/enterprise) with **NPM_TOKEN**
as a secret.
```yaml
npm:
registry: "http://myregistry:8081"
```

Drone plugin to publish files and artifacts to a NPM registry. For the usage information and a listing of the available options please take a look at [the docs](DOCS.md).
## Binary
## Build
Build the binary using `make`:
Build the binary with the following commands:
```
make deps build
```
### Example
```sh
./drone-npm <<EOF
{
"repo": {
"clone_url": "git://github.com/drone/drone",
"owner": "drone",
"name": "drone",
"full_name": "drone/drone"
},
"system": {
"link_url": "https://beta.drone.io"
},
"build": {
"number": 22,
"status": "success",
"started_at": 1421029603,
"finished_at": 1421029813,
"message": "Update the Readme",
"author": "johnsmith",
"author_email": "john.smith@gmail.com"
"event": "push",
"branch": "master",
"commit": "436b7a6e2abaddfd35740527353e78a227ddcb2c",
"ref": "refs/heads/master"
},
"workspace": {
"root": "/drone/src",
"path": "/drone/src/github.com/drone/drone"
},
"vargs": {
"username": "octocat",
"password": "pa$$word",
"email": "octocat@github.com"
}
}
EOF
export GO15VENDOREXPERIMENT=1
go build
go test
```
## Docker
Build the container using `make`:
Build the docker image with the following commands:
```
make deps docker
export GO15VENDOREXPERIMENT=1
GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build -a -tags netgo
```
### Example
Please note incorrectly building the image for the correct x64 linux and with GCO disabled will result in an error when running the Docker image:
```
docker: Error response from daemon: Container command
'/bin/drone-git' not found or does not exist..
```
## Usage
Push to public NPM registry
```sh
docker run -i plugins/drone-npm <<EOF

# Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/>&nbsp;[![Build Status](https://travis-ci.org/Sirupsen/logrus.svg?branch=master)](https://travis-ci.org/Sirupsen/logrus)&nbsp;[![GoDoc](https://godoc.org/github.com/Sirupsen/logrus?status.svg)](https://godoc.org/github.com/Sirupsen/logrus)
Logrus is a structured logger for Go (golang), completely API compatible with
the standard library logger. [Godoc][godoc]. **Please note the Logrus API is not
yet stable (pre 1.0). Logrus itself is completely stable and has been used in
many large deployments. The core API is unlikely to change much but please
version control your Logrus to make sure you aren't fetching latest `master` on
every build.**
Nicely color-coded in development (when a TTY is attached, otherwise just
plain text):
![Colored](http://i.imgur.com/PY7qMwd.png)
With `log.SetFormatter(&log.JSONFormatter{})`, for easy parsing by logstash
or Splunk:
```json
{"animal":"walrus","level":"info","msg":"A group of walrus emerges from the
ocean","size":10,"time":"2014-03-10 19:57:38.562264131 -0400 EDT"}
{"level":"warning","msg":"The group's number increased tremendously!",
"number":122,"omg":true,"time":"2014-03-10 19:57:38.562471297 -0400 EDT"}
{"animal":"walrus","level":"info","msg":"A giant walrus appears!",
"size":10,"time":"2014-03-10 19:57:38.562500591 -0400 EDT"}
{"animal":"walrus","level":"info","msg":"Tremendously sized cow enters the ocean.",
"size":9,"time":"2014-03-10 19:57:38.562527896 -0400 EDT"}
{"level":"fatal","msg":"The ice breaks!","number":100,"omg":true,
"time":"2014-03-10 19:57:38.562543128 -0400 EDT"}
```
With the default `log.SetFormatter(&log.TextFormatter{})` when a TTY is not
attached, the output is compatible with the
[logfmt](http://godoc.org/github.com/kr/logfmt) format:
```text
time="2015-03-26T01:27:38-04:00" level=debug msg="Started observing beach" animal=walrus number=8
time="2015-03-26T01:27:38-04:00" level=info msg="A group of walrus emerges from the ocean" animal=walrus size=10
time="2015-03-26T01:27:38-04:00" level=warning msg="The group's number increased tremendously!" number=122 omg=true
time="2015-03-26T01:27:38-04:00" level=debug msg="Temperature changes" temperature=-4
time="2015-03-26T01:27:38-04:00" level=panic msg="It's over 9000!" animal=orca size=9009
time="2015-03-26T01:27:38-04:00" level=fatal msg="The ice breaks!" err=&{0x2082280c0 map[animal:orca size:9009] 2015-03-26 01:27:38.441574009 -0400 EDT panic It's over 9000!} number=100 omg=true
exit status 1
```
#### Example
The simplest way to use Logrus is simply the package-level exported logger:
```go
package main
import (
log "github.com/Sirupsen/logrus"
)
func main() {
log.WithFields(log.Fields{
"animal": "walrus",
}).Info("A walrus appears")
}
```
Note that it's completely api-compatible with the stdlib logger, so you can
replace your `log` imports everywhere with `log "github.com/Sirupsen/logrus"`
and you'll now have the flexibility of Logrus. You can customize it all you
want:
```go
package main
import (
"os"
log "github.com/Sirupsen/logrus"
)
func init() {
// Log as JSON instead of the default ASCII formatter.
log.SetFormatter(&log.JSONFormatter{})
// Output to stderr instead of stdout, could also be a file.
log.SetOutput(os.Stderr)
// Only log the warning severity or above.
log.SetLevel(log.WarnLevel)
}
func main() {
log.WithFields(log.Fields{
"animal": "walrus",
"size": 10,
}).Info("A group of walrus emerges from the ocean")
log.WithFields(log.Fields{
"omg": true,
"number": 122,
}).Warn("The group's number increased tremendously!")
log.WithFields(log.Fields{
"omg": true,
"number": 100,
}).Fatal("The ice breaks!")
// A common pattern is to re-use fields between logging statements by re-using
// the logrus.Entry returned from WithFields()
contextLogger := log.WithFields(log.Fields{
"common": "this is a common field",
"other": "I also should be logged always",
})
contextLogger.Info("I'll be logged with common and other field")
contextLogger.Info("Me too")
}
```
For more advanced usage such as logging to multiple locations from the same
application, you can also create an instance of the `logrus` Logger:
```go
package main
import (
"github.com/Sirupsen/logrus"
)
// Create a new instance of the logger. You can have any number of instances.
var log = logrus.New()
func main() {
// The API for setting attributes is a little different than the package level
// exported logger. See Godoc.
log.Out = os.Stderr
log.WithFields(logrus.Fields{
"animal": "walrus",
"size": 10,
}).Info("A group of walrus emerges from the ocean")
}
```
#### Fields
Logrus encourages careful, structured logging though logging fields instead of
long, unparseable error messages. For example, instead of: `log.Fatalf("Failed
to send event %s to topic %s with key %d")`, you should log the much more
discoverable:
```go
log.WithFields(log.Fields{
"event": event,
"topic": topic,
"key": key,
}).Fatal("Failed to send event")
```
We've found this API forces you to think about logging in a way that produces
much more useful logging messages. We've been in countless situations where just
a single added field to a log statement that was already there would've saved us
hours. The `WithFields` call is optional.
In general, with Logrus using any of the `printf`-family functions should be
seen as a hint you should add a field, however, you can still use the
`printf`-family functions with Logrus.
#### Hooks
You can add hooks for logging levels. For example to send errors to an exception
tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to
multiple places simultaneously, e.g. syslog.
Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in
`init`:
```go
import (
log "github.com/Sirupsen/logrus"
"gopkg.in/gemnasium/logrus-airbrake-hook.v2" // the package is named "aibrake"
logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog"
"log/syslog"
)
func init() {
// Use the Airbrake hook to report errors that have Error severity or above to
// an exception tracker. You can create custom hooks, see the Hooks section.
log.AddHook(airbrake.NewHook(123, "xyz", "production"))
hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
if err != nil {
log.Error("Unable to connect to local syslog daemon")
} else {
log.AddHook(hook)
}
}
```
Note: Syslog hook also support connecting to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). For the detail, please check the [syslog hook README](hooks/syslog/README.md).

#### Level logging
Logrus has six logging levels: Debug, Info, Warning, Error, Fatal and Panic.
```go
log.Debug("Useful debugging information.")
log.Info("Something noteworthy happened!")
log.Warn("You should probably take a look at this.")
log.Error("Something failed but I'm not quitting.")
// Calls os.Exit(1) after logging
log.Fatal("Bye.")
// Calls panic() after logging
log.Panic("I'm bailing.")
```
You can set the logging level on a `Logger`, then it will only log entries with
that severity or anything above it:
```go
// Will log anything that is info or above (warn, error, fatal, panic). Default.
log.SetLevel(log.InfoLevel)
```
It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose
environment if your application has that.
#### Entries
Besides the fields added with `WithField` or `WithFields` some fields are
automatically added to all logging events:
1. `time`. The timestamp when the entry was created.
2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after
the `AddFields` call. E.g. `Failed to send event.`
3. `level`. The logging level. E.g. `info`.
#### Environments
Logrus has no notion of environment.
If you wish for hooks and formatters to only be used in specific environments,
you should handle that yourself. For example, if your application has a global
variable `Environment`, which is a string representation of the environment you
could do:
```go
import (
log "github.com/Sirupsen/logrus"
)
init() {
// do something here to set environment depending on an environment variable
// or command-line flag
if Environment == "production" {
log.SetFormatter(&log.JSONFormatter{})
} else {
// The TextFormatter is default, you don't actually have to do this.
log.SetFormatter(&log.TextFormatter{})
}
}
```
This configuration is how `logrus` was intended to be used, but JSON in
production is mostly only useful if you do log aggregation with tools like
Splunk or Logstash.
#### Formatters
The built-in logging formatters are:
* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise
without colors.
* *Note:* to force colored output when there is no TTY, set the `ForceColors`
field to `true`. To force no colored output even if there is a TTY set the
`DisableColors` field to `true`
* `logrus.JSONFormatter`. Logs fields as JSON.
* `logrus/formatters/logstash.LogstashFormatter`. Logs fields as [Logstash](http://logstash.net) Events.
```go
logrus.SetFormatter(&logstash.LogstashFormatter{Type: "application_name"})
```
Third party logging formatters:
* [`prefixed`](https://github.com/x-cray/logrus-prefixed-formatter). Displays log entry source along with alternative layout.
* [`zalgo`](https://github.com/aybabtme/logzalgo). Invoking the P͉̫o̳̼̊w̖͈̰͎e̬͔̭͂r͚̼̹̲ ̫͓͉̳͈ō̠͕͖̚f̝͍̠ ͕̲̞͖͑Z̖̫̤̫ͪa͉̬͈̗l͖͎g̳̥o̰̥̅!̣͔̲̻͊̄ ̙̘̦̹̦.
You can define your formatter by implementing the `Formatter` interface,
requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a
`Fields` type (`map[string]interface{}`) with all your fields as well as the
default ones (see Entries section above):
```go
type MyJSONFormatter struct {
}
log.SetFormatter(new(MyJSONFormatter))
func (f *MyJSONFormatter) Format(entry *Entry) ([]byte, error) {
// Note this doesn't include Time, Level and Message which are available on
// the Entry. Consult `godoc` on information about those fields or read the
// source of the official loggers.
serialized, err := json.Marshal(entry.Data)
if err != nil {
return nil, fmt.Errorf("Failed to marshal fields to JSON, %v", err)
}
return append(serialized, '\n'), nil
}
```
#### Logger as an `io.Writer`
Logrus can be transformed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it.
```go
w := logger.Writer()
defer w.Close()
srv := http.Server{
// create a stdlib log.Logger that writes to
// logrus.Logger.
ErrorLog: log.New(w, "", 0),
}
```
Each line written to that writer will be printed the usual way, using formatters
and hooks. The level for those entries is `info`.
#### Rotation
Log rotation is not provided with Logrus. Log rotation should be done by an
external program (like `logrotate(8)`) that can compress and delete old log
entries. It should not be a feature of the application-level logger.
#### Tools
| Tool | Description |
| ---- | ----------- |
|[Logrus Mate](https://github.com/gogap/logrus_mate)|Logrus mate is a tool for Logrus to manage loggers, you can initial logger's level, hook and formatter by config file, the logger will generated with different config at different environment.|
#### Testing
Logrus has a built in facility for asserting the presence of log messages. This is implemented through the `test` hook and provides:
* decorators for existing logger (`test.NewLocal` and `test.NewGlobal`) which basically just add the `test` hook
* a test logger (`test.NewNullLogger`) that just records log messages (and does not output any):
```go
logger, hook := NewNullLogger()
logger.Error("Hello error")
assert.Equal(1, len(hook.Entries))
assert.Equal(logrus.ErrorLevel, hook.LastEntry().Level)
assert.Equal("Hello error", hook.LastEntry().Message)
hook.Reset()
assert.Nil(hook.LastEntry())
```

# Syslog Hooks for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/>
## Usage
```go
import (
"log/syslog"
"github.com/Sirupsen/logrus"
logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog"
)
func main() {
log := logrus.New()
hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
if err == nil {
log.Hooks.Add(hook)
}
}
```
If you want to connect to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). Just assign empty string to the first two parameters of `NewSyslogHook`. It should look like the following.
```go
import (
"log/syslog"
"github.com/Sirupsen/logrus"
logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog"
)
func main() {
log := logrus.New()
hook, err := logrus_syslog.NewSyslogHook("", "", syslog.LOG_INFO, "")
if err == nil {
log.Hooks.Add(hook)
}
}

# Change Log
**ATTN**: This project uses [semantic versioning](http://semver.org/).
## [Unreleased]
## [1.18.0] - 2016-06-27
### Added
- `./runtests` test runner with coverage tracking by default
- testing on OS X
- testing on Windows
- `UintFlag`, `Uint64Flag`, and `Int64Flag` types and supporting code
### Changed
- Use spaces for alignment in help/usage output instead of tabs, making the
output alignment consistent regardless of tab width
### Fixed
- Printing of command aliases in help text
- Printing of visible flags for both struct and struct pointer flags
- Display the `help` subcommand when using `CommandCategories`
- No longer swallows `panic`s that occur within the `Action`s themselves when
detecting the signature of the `Action` field
## [1.17.0] - 2016-05-09
### Added
- Pluggable flag-level help text rendering via `cli.DefaultFlagStringFunc`
- `context.GlobalBoolT` was added as an analogue to `context.GlobalBool`
- Support for hiding commands by setting `Hidden: true` -- this will hide the
commands in help output
### Changed
- `Float64Flag`, `IntFlag`, and `DurationFlag` default values are no longer
quoted in help text output.
- All flag types now include `(default: {value})` strings following usage when a
default value can be (reasonably) detected.
- `IntSliceFlag` and `StringSliceFlag` usage strings are now more consistent
with non-slice flag types
- Apps now exit with a code of 3 if an unknown subcommand is specified
(previously they printed "No help topic for...", but still exited 0. This
makes it easier to script around apps built using `cli` since they can trust
that a 0 exit code indicated a successful execution.
- cleanups based on [Go Report Card
feedback](https://goreportcard.com/report/github.com/urfave/cli)
## [1.16.0] - 2016-05-02
### Added
- `Hidden` field on all flag struct types to omit from generated help text
### Changed
- `BashCompletionFlag` (`--enable-bash-completion`) is now omitted from
generated help text via the `Hidden` field
### Fixed
- handling of error values in `HandleAction` and `HandleExitCoder`
## [1.15.0] - 2016-04-30
### Added
- This file!
- Support for placeholders in flag usage strings
- `App.Metadata` map for arbitrary data/state management
- `Set` and `GlobalSet` methods on `*cli.Context` for altering values after
parsing.
- Support for nested lookup of dot-delimited keys in structures loaded from
YAML.
### Changed
- The `App.Action` and `Command.Action` now prefer a return signature of
`func(*cli.Context) error`, as defined by `cli.ActionFunc`. If a non-nil
`error` is returned, there may be two outcomes:
- If the error fulfills `cli.ExitCoder`, then `os.Exit` will be called
automatically
- Else the error is bubbled up and returned from `App.Run`
- Specifying an `Action` with the legacy return signature of
`func(*cli.Context)` will produce a deprecation message to stderr
- Specifying an `Action` that is not a `func` type will produce a non-zero exit
from `App.Run`
- Specifying an `Action` func that has an invalid (input) signature will
produce a non-zero exit from `App.Run`
### Deprecated
- <a name="deprecated-cli-app-runandexitonerror"></a>
`cli.App.RunAndExitOnError`, which should now be done by returning an error
that fulfills `cli.ExitCoder` to `cli.App.Run`.
- <a name="deprecated-cli-app-action-signature"></a> the legacy signature for
`cli.App.Action` of `func(*cli.Context)`, which should now have a return
signature of `func(*cli.Context) error`, as defined by `cli.ActionFunc`.
### Fixed
- Added missing `*cli.Context.GlobalFloat64` method
## [1.14.0] - 2016-04-03 (backfilled 2016-04-25)
### Added
- Codebeat badge
- Support for categorization via `CategorizedHelp` and `Categories` on app.
### Changed

# GoDotEnv [![wercker status](https://app.wercker.com/status/507594c2ec7e60f19403a568dfea0f78 "wercker status")](https://app.wercker.com/project/bykey/507594c2ec7e60f19403a568dfea0f78)
A Go (golang) port of the Ruby dotenv project (which loads env vars from a .env file)
From the original Library:
> Storing configuration in the environment is one of the tenets of a twelve-factor app. Anything that is likely to change between deployment environments–such as resource handles for databases or credentials for external services–should be extracted from the code into environment variables.
>
> But it is not always practical to set environment variables on development machines or continuous integration servers where multiple projects are run. Dotenv load variables from a .env file into ENV when the environment is bootstrapped.
It can be used as a library (for loading in env for your own daemons etc) or as a bin command.
There is test coverage and CI for both linuxish and windows environments, but I make no guarantees about the bin version working on windows.
## Installation
As a library
```shell
go get github.com/joho/godotenv
```
or if you want to use it as a bin command
```shell
go get github.com/joho/godotenv/cmd/godotenv
```
## Usage
Add your application configuration to your `.env` file in the root of your project:
```shell
S3_BUCKET=YOURS3BUCKET
SECRET_KEY=YOURSECRETKEYGOESHERE
```
Then in your Go app you can do something like
```go
package main
import (
"github.com/joho/godotenv"
"log"
"os"
)
func main() {
err := godotenv.Load()
if err != nil {
log.Fatal("Error loading .env file")
}
s3Bucket := os.Getenv("S3_BUCKET")
secretKey := os.Getenv("SECRET_KEY")
// now do something with s3 or whatever
}
```
If you're even lazier than that, you can just take advantage of the autoload package which will read in `.env` on import
```go
import _ "github.com/joho/godotenv/autoload"
```
While `.env` in the project root is the default, you don't have to be constrained, both examples below are 100% legit
```go
_ = godotenv.Load("somerandomfile")
_ = godotenv.Load("filenumberone.env", "filenumbertwo.env")
```
If you want to be really fancy with your env file you can do comments and exports (below is a valid env file)
```shell
# I am a comment and that is OK
SOME_VAR=someval
FOO=BAR # comments at line end are OK too
export BAR=BAZ
```
Or finally you can do YAML(ish) style
```yaml
FOO: bar
BAR: baz
```
as a final aside, if you don't want godotenv munging your env you can just get a map back instead
```go
var myEnv map[string]string
myEnv, err := godotenv.Read()
s3Bucket := myEnv["S3_BUCKET"]
```
### Command Mode
Assuming you've installed the command as above and you've got `$GOPATH/bin` in your `$PATH`
```
godotenv -f /some/path/to/.env some_command with some args
```
If you don't specify `-f` it will fall back on the default of loading `.env` in `PWD`
## Contributing
Contributions are most welcome! The parser itself is pretty stupidly naive and I wouldn't be surprised if it breaks with edge cases.
*code changes without tests will not be accepted*
1. Fork it
2. Create your feature branch (`git checkout -b my-new-feature`)
3. Commit your changes (`git commit -am 'Added some feature'`)
4. Push to the branch (`git push origin my-new-feature`)
5. Create new Pull Request
## CI
Linux: [![wercker status](https://app.wercker.com/status/507594c2ec7e60f19403a568dfea0f78/m "wercker status")](https://app.wercker.com/project/bykey/507594c2ec7e60f19403a568dfea0f78) Windows: [![Build status](https://ci.appveyor.com/api/projects/status/9v40vnfvvgde64u4)](https://ci.appveyor.com/project/joho/godotenv)
## Who?
The original library [dotenv](https://github.com/bkeepers/dotenv) was written by [Brandon Keepers](http://opensoul.org/), and this port was done by [John Barton](http://whoisjohnbarton.com) based off the tests/fixtures in the original library.
