// Buffers
//
// Connections buffer network input and output to reduce the number
// of system calls when reading or writing messages.
//
// Write buffers are also used for constructing WebSocket frames. See RFC 6455,
// Section 5 for a discussion of message framing. A WebSocket frame header is
// written to the network each time a write buffer is flushed to the network.
// Decreasing the size of the write buffer can increase the amount of framing
// overhead on the connection.
//
// The buffer sizes in bytes are specified by the ReadBufferSize and
// WriteBufferSize fields in the Dialer and Upgrader. The Dialer uses a default
// size of 4096 when a buffer size field is set to zero. The Upgrader reuses
// buffers created by the HTTP server when a buffer size field is set to zero.
// The HTTP server buffers have a size of 4096 at the time of this writing.
//
// The buffer sizes do not limit the size of a message that can be read or
// written by a connection.
//
// Buffers are held for the lifetime of the connection by default. If the
// Dialer or Upgrader WriteBufferPool field is set, then a connection holds the
// write buffer only when writing a message.
//
// Applications should tune the buffer sizes to balance memory use and
// performance. Increasing the buffer size uses more memory, but can reduce the
// number of system calls to read or write the network. In the case of writing,
// increasing the buffer size can reduce the number of frame headers written to
// the network.
//
// Some guidelines for setting buffer parameters are:
//
// Limit the buffer sizes to the maximum expected message size. Buffers larger
// than the largest message do not provide any benefit.
//
// Depending on the distribution of message sizes, setting the buffer size to
// a value less than the maximum expected message size can greatly reduce memory
// use with a small impact on performance. Here's an example: If 99% of the
// messages are smaller than 256 bytes and the maximum message size is 512
// bytes, then a buffer size of 256 bytes will result in 1.01 more system calls
// than a buffer size of 512 bytes. The memory savings is 50%.
//
// A write buffer pool is useful when the application has a modest number
// writes over a large number of connections. when buffers are pooled, a larger
// buffer size has a reduced impact on total memory use and has the benefit of
// reducing system calls and frame overhead.
//
// Compression EXPERIMENTAL
//
// Per message compression extensions (RFC 7692) are experimentally supported

# go-homedir
This is a Go library for detecting the user's home directory without
the use of cgo, so the library can be used in cross-compilation environments.
Usage is incredibly simple, just call `homedir.Dir()` to get the home directory
for a user, and `homedir.Expand()` to expand the `~` in a path to the home
directory.
**Why not just use `os/user`?** The built-in `os/user` package requires
cgo on Darwin systems. This means that any Go code that uses that package
cannot cross compile. But 99% of the time the use for `os/user` is just to
retrieve the home directory, which we can do for the current user without
cgo. This library does that, enabling cross-compilation.

* concurrent.Map: backport sync.Map for go below 1.9
* concurrent.Executor: goroutine with explicit ownership and cancellable
# concurrent.Map
because sync.Map is only available in go 1.9, we can use concurrent.Map to make code portable
```go
m := concurrent.NewMap()
m.Store("hello", "world")
elem, found := m.Load("hello")
// elem will be "world"
// found will be true
```
# concurrent.Executor
```go
executor := concurrent.NewUnboundedExecutor()
executor.Go(func(ctx context.Context) {
everyMillisecond := time.NewTicker(time.Millisecond)
for {
select {
case <-ctx.Done():
fmt.Println("goroutine exited")
return
case <-everyMillisecond.C:
// do something
}
}
})
time.Sleep(time.Second)
executor.StopAndWaitForever()
fmt.Println("executor stopped")
```
attach goroutine to executor instance, so that we can
* cancel it by stop the executor with Stop/StopAndWait/StopAndWaitForever
* handle panic by callback: the default behavior will no longer crash your application

The zerolog package provides a fast and simple logger dedicated to JSON output.
Zerolog's API is designed to provide both a great developer experience and stunning [performance](#benchmarks). Its unique chaining API allows zerolog to write JSON (or CBOR) log events by avoiding allocations and reflection.
Uber's [zap](https://godoc.org/go.uber.org/zap) library pioneered this approach. Zerolog is taking this concept to the next level with a simpler to use API and even better performance.
To keep the code base and the API simple, zerolog focuses on efficient structured logging only. Pretty logging on the console is made possible using the provided (but inefficient) [`zerolog.ConsoleWriter`](#pretty-logging).

```
## Getting Started
### Simple Logging Example
For simple logging, import the global logger package **github.com/rs/zerolog/log**
```go
package main
import (
"github.com/rs/zerolog"
"github.com/rs/zerolog/log"
)
func main() {
// UNIX Time is faster and smaller than most timestamps
// If you set zerolog.TimeFieldFormat to an empty string,
// logs will write with UNIX time
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
log.Print("hello world")
}
// Output: {"time":1516134303,"level":"debug","message":"hello world"}
```
> Note: By default log writes to `os.Stderr`
> Note: The default log level for `log.Print` is *debug*
### Contextual Logging
**zerolog** allows data to be added to log messages in the form of key:value pairs. The data added to the message adds "context" about the log event that can be critical for debugging as well as myriad other purposes. An example of this is below:
```go
package main
import (
"github.com/rs/zerolog"
"github.com/rs/zerolog/log"
)
func main() {
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
log.Debug().
Str("Scale", "833 cents").
Float64("Interval", 833.09).
Msg("Fibonacci is everywhere")
log.Debug().
Str("Name", "Tom").
Send()
}
// Output: {"level":"debug","Scale":"833 cents","Interval":833.09,"time":1562212768,"message":"Fibonacci is everywhere"}
// Output: {"level":"debug","Name":"Tom","time":1562212768}
```
> You'll note in the above example that when adding contextual fields, the fields are strongly typed. You can find the full list of supported fields [here](#standard-types)
### Leveled Logging
#### Simple Leveled Logging Example
```go
package main
import (
"github.com/rs/zerolog"
"github.com/rs/zerolog/log"
)
func main() {
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
log.Info().Msg("hello world")
}
// Output: {"time":1516134303,"level":"info","message":"hello world"}
```
> It is very important to note that when using the **zerolog** chaining API, as shown above (`log.Info().Msg("hello world"`), the chain must have either the `Msg` or `Msgf` method call. If you forget to add either of these, the log will not occur and there is no compile time error to alert you of this.
**zerolog** allows for logging at the following levels (from highest to lowest):
* panic (`zerolog.PanicLevel`, 5)
* fatal (`zerolog.FatalLevel`, 4)
* error (`zerolog.ErrorLevel`, 3)
* warn (`zerolog.WarnLevel`, 2)
* info (`zerolog.InfoLevel`, 1)
* debug (`zerolog.DebugLevel`, 0)
* trace (`zerolog.TraceLevel`, -1)
You can set the Global logging level to any of these options using the `SetGlobalLevel` function in the zerolog package, passing in one of the given constants above, e.g. `zerolog.InfoLevel` would be the "info" level. Whichever level is chosen, all logs with a level greater than or equal to that level will be written. To turn off logging entirely, pass the `zerolog.Disabled` constant.
#### Setting Global Log Level
This example uses command-line flags to demonstrate various outputs depending on the chosen log level.
```go
package main
import (
"flag"
"github.com/rs/zerolog"
"github.com/rs/zerolog/log"
)
func main() {
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
debug := flag.Bool("debug", false, "sets log level to debug")
flag.Parse()
// Default level for this example is info, unless debug flag is present
zerolog.SetGlobalLevel(zerolog.InfoLevel)
if *debug {
zerolog.SetGlobalLevel(zerolog.DebugLevel)
}
log.Debug().Msg("This message appears only when log level set to Debug")
log.Info().Msg("This message appears when log level set to Debug or Info")
if e := log.Debug(); e.Enabled() {
// Compute log output only if enabled.
value := "bar"
e.Str("foo", value).Msg("some debug message")
}
}
```
Info Output (no flag)
```bash
$ ./logLevelExample
{"time":1516387492,"level":"info","message":"This message appears when log level set to Debug or Info"}
```
Debug Output (debug flag set)
```bash
$ ./logLevelExample -debug
{"time":1516387573,"level":"debug","message":"This message appears only when log level set to Debug"}
{"time":1516387573,"level":"info","message":"This message appears when log level set to Debug or Info"}
{"time":1516387573,"level":"debug","foo":"bar","message":"some debug message"}
```
#### Logging without Level or Message
You may choose to log without a specific level by using the `Log` method. You may also write without a message by setting an empty string in the `msg string` parameter of the `Msg` method. Both are demonstrated in the example below.
```go
package main
import (
"github.com/rs/zerolog"
"github.com/rs/zerolog/log"
)
func main() {
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
log.Log().
Str("foo", "bar").
Msg("")
}
// Output: {"time":1494567715,"foo":"bar"}
```
#### Logging Fatal Messages
```go
package main
import (
"errors"
"github.com/rs/zerolog"
"github.com/rs/zerolog/log"
)
func main() {
err := errors.New("A repo man spends his life getting into tense situations")
service := "myservice"
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
log.Fatal().
Err(err).
Str("service", service).
Msgf("Cannot start %s", service)
}
// Output: {"time":1516133263,"level":"fatal","error":"A repo man spends his life getting into tense situations","service":"myservice","message":"Cannot start myservice"}
// exit status 1
```
> NOTE: Using `Msgf` generates one allocation even when the logger is disabled.
### Create logger instance to manage different outputs
```go
logger := zerolog.New(os.Stderr).With().Timestamp().Logger()
logger.Info().Str("foo", "bar").Msg("hello world")
// Output: {"level":"info","time":1494567715,"message":"hello world","foo":"bar"}
```
### Sub-loggers let you chain loggers with additional context
```go
sublogger := log.With().
Str("component", "foo").
Logger()
sublogger.Info().Msg("hello world")
// Output: {"level":"info","time":1494567715,"message":"hello world","component":"foo"}
```
### Pretty logging
To log a human-friendly, colorized output, use `zerolog.ConsoleWriter`:
```go
log.Logger = log.Output(zerolog.ConsoleWriter{Out: os.Stderr})
log.Info().Str("foo", "bar").Msg("Hello world")
// Output: 3:04PM INF Hello World foo=bar
```
To customize the configuration and formatting:
```go
output := zerolog.ConsoleWriter{Out: os.Stdout, TimeFormat: time.RFC3339}
output.FormatLevel = func(i interface{}) string {
return strings.ToUpper(fmt.Sprintf("| %-6s|", i))
}
output.FormatMessage = func(i interface{}) string {
return fmt.Sprintf("***%s****", i)
}
output.FormatFieldName = func(i interface{}) string {
return fmt.Sprintf("%s:", i)
}
output.FormatFieldValue = func(i interface{}) string {
return strings.ToUpper(fmt.Sprintf("%s", i))
}
log := zerolog.New(output).With().Timestamp().Logger()
log.Info().Str("foo", "bar").Msg("Hello World")
// Output: 2006-01-02T15:04:05Z07:00 | INFO | ***Hello World**** foo:BAR
```
### Sub dictionary
```go
log.Info().
Str("foo", "bar").
Dict("dict", zerolog.Dict().
Str("bar", "baz").
Int("n", 1),
).Msg("hello world")
// Output: {"level":"info","time":1494567715,"foo":"bar","dict":{"bar":"baz","n":1},"message":"hello world"}
```
### Customize automatic field names
```go
zerolog.TimestampFieldName = "t"
zerolog.LevelFieldName = "l"
zerolog.MessageFieldName = "m"
log.Info().Msg("hello world")
// Output: {"l":"info","t":1494567715,"m":"hello world"}
```
### Add contextual fields to the global logger
```go
log.Logger = log.With().Str("foo", "bar").Logger()
```
### Add file and line number to log
```go
log.Logger = log.With().Caller().Logger()
log.Info().Msg("hello world")
// Output: {"level": "info", "message": "hello world", "caller": "/go/src/your_project/some_file:21"}
```
### Thread-safe, lock-free, non-blocking writer
If your writer might be slow or not thread-safe and you need your log producers to never get slowed down by a slow writer, you can use a `diode.Writer` as follow:
```go
wr := diode.NewWriter(os.Stdout, 1000, 10*time.Millisecond, func(missed int) {
fmt.Printf("Logger Dropped %d messages", missed)
})
log := zerolog.New(w)
log.Print("test")
```
You will need to install `code.cloudfoundry.org/go-diodes` to use this feature.
### Log Sampling
```go
sampled := log.Sample(&zerolog.BasicSampler{N: 10})
sampled.Info().Msg("will be logged every 10 messages")
// Output: {"time":1494567715,"level":"info","message":"will be logged every 10 messages"}
```
More advanced sampling:
```go
// Will let 5 debug messages per period of 1 second.
// Over 5 debug message, 1 every 100 debug messages are logged.
// Other levels are not sampled.
sampled := log.Sample(zerolog.LevelSampler{
DebugSampler: &zerolog.BurstSampler{
Burst: 5,
Period: 1*time.Second,
NextSampler: &zerolog.BasicSampler{N: 100},
},
})
sampled.Debug().Msg("hello world")
// Output: {"time":1494567715,"level":"debug","message":"hello world"}
```
### Hooks
```go
type SeverityHook struct{}
func (h SeverityHook) Run(e *zerolog.Event, level zerolog.Level, msg string) {
if level != zerolog.NoLevel {
e.Str("severity", level.String())
}
}
hooked := log.Hook(SeverityHook{})
hooked.Warn().Msg("")
// Output: {"level":"warn","severity":"warn"}
```
### Pass a sub-logger by context
```go
ctx := log.With().Str("component", "module").Logger().WithContext(ctx)
log.Ctx(ctx).Info().Msg("hello world")
// Output: {"component":"module","level":"info","message":"hello world"}
```
### Set as standard logger output
```go
log := zerolog.New(os.Stdout).With().
Str("foo", "bar").
Logger()
stdlog.SetFlags(0)
stdlog.SetOutput(log)
stdlog.Print("hello world")
// Output: {"foo":"bar","message":"hello world"}
```
### Integration with `net/http`
The `github.com/rs/zerolog/hlog` package provides some helpers to integrate zerolog with `http.Handler`.
In this example we use [alice](https://github.com/justinas/alice) to install logger for better readability.
```go
log := zerolog.New(os.Stdout).With().
Timestamp().
Str("role", "my-service").
Str("host", host).
Logger()
c := alice.New()
// Install the logger handler with default output on the console
c = c.Append(hlog.NewHandler(log))
// Install some provided extra handler to set some request's context fields.
// Thanks to those handler, all our logs will come with some pre-populated fields.
c = c.Append(hlog.AccessHandler(func(r *http.Request, status, size int, duration time.Duration) {
hlog.FromRequest(r).Info().
Str("method", r.Method).
Str("url", r.URL.String()).
Int("status", status).
Int("size", size).
Dur("duration", duration).
Msg("")
}))
c = c.Append(hlog.RemoteAddrHandler("ip"))
c = c.Append(hlog.UserAgentHandler("user_agent"))
c = c.Append(hlog.RefererHandler("referer"))
c = c.Append(hlog.RequestIDHandler("req_id", "Request-Id"))
// Here is your final handler
h := c.Then(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
// Get the logger from the request's context. You can safely assume it
// will be always there: if the handler is removed, hlog.FromRequest
// will return a no-op logger.
hlog.FromRequest(r).Info().
Str("user", "current user").
Str("status", "ok").
Msg("Something happened")
// Output: {"level":"info","time":"2001-02-03T04:05:06Z","role":"my-service","host":"local-hostname","req_id":"b4g0l5t6tfid6dtrapu0","user":"current user","status":"ok","message":"Something happened"}
}))
http.Handle("/", h)
if err := http.ListenAndServe(":8080", nil); err != nil {
log.Fatal().Err(err).Msg("Startup failed")
}
```
## Global Settings
Some settings can be changed and will by applied to all loggers:
* `log.Logger`: You can set this value to customize the global logger (the one used by package level methods).
* `zerolog.SetGlobalLevel`: Can raise the minimum level of all loggers. Set this to `zerolog.Disabled` to disable logging altogether (quiet mode).
* `zerolog.DisableSampling`: If argument is `true`, all sampled loggers will stop sampling and issue 100% of their log events.
* `zerolog.TimestampFieldName`: Can be set to customize `Timestamp` field name.
* `zerolog.LevelFieldName`: Can be set to customize level field name.
* `zerolog.MessageFieldName`: Can be set to customize message field name.
* `zerolog.ErrorFieldName`: Can be set to customize `Err` field name.
* `zerolog.TimeFieldFormat`: Can be set to customize `Time` field value formatting. If set with `zerolog.TimeFormatUnix`, `zerolog.TimeFormatUnixMs` or `zerolog.TimeFormatUnixMicro`, times are formated as UNIX timestamp.
* `zerolog.DurationFieldUnit`: Can be set to customize the unit for time.Duration type fields added by `Dur` (default: `time.Millisecond`).
* `zerolog.DurationFieldInteger`: If set to `true`, `Dur` fields are formatted as integers instead of floats (default: `false`).
* `zerolog.ErrorHandler`: Called whenever zerolog fails to write an event on its output. If not set, an error is printed on the stderr. This handler must be thread safe and non-blocking.
## Field Types
### Standard Types
* `Str`
* `Bool`
* `Int`, `Int8`, `Int16`, `Int32`, `Int64`
* `Uint`, `Uint8`, `Uint16`, `Uint32`, `Uint64`
* `Float32`, `Float64`
### Advanced Fields
* `Err`: Takes an `error` and render it as a string using the `zerolog.ErrorFieldName` field name.
* `Timestamp`: Insert a timestamp field with `zerolog.TimestampFieldName` field name and formatted using `zerolog.TimeFieldFormat`.
* `Time`: Adds a field with the time formated with the `zerolog.TimeFieldFormat`.
* `Dur`: Adds a field with a `time.Duration`.
* `Dict`: Adds a sub-key/value as a field of the event.
* `Interface`: Uses reflection to marshal the type.
## Binary Encoding
In addition to the default JSON encoding, `zerolog` can produce binary logs using [CBOR](http://cbor.io) encoding. The choice of encoding can be decided at compile time using the build tag `binary_log` as follows:
```bash
go build -tags binary_log .
```
To Decode binary encoded log files you can use any CBOR decoder. One has been tested to work
with zerolog library is [CSD](https://github.com/toravir/csd/).

Using Uber's zap comparison benchmark:
Log a message and 10 fields:
| Library | Time | Bytes Allocated | Objects Allocated |
| :--- | :---: | :---: | :---: |
| zerolog | 767 ns/op | 552 B/op | 6 allocs/op |
| :zap: zap | 848 ns/op | 704 B/op | 2 allocs/op |
| :zap: zap (sugared) | 1363 ns/op | 1610 B/op | 20 allocs/op |
| go-kit | 3614 ns/op | 2895 B/op | 66 allocs/op |

| apex/log | 15332 ns/op | 3832 B/op | 65 allocs/op |
| log15 | 20657 ns/op | 5632 B/op | 93 allocs/op |
Log a message with a logger that already has 10 fields of context:
| Library | Time | Bytes Allocated | Objects Allocated |
| :--- | :---: | :---: | :---: |
| zerolog | 52 ns/op | 0 B/op | 0 allocs/op |
| :zap: zap | 283 ns/op | 0 B/op | 0 allocs/op |
| :zap: zap (sugared) | 337 ns/op | 80 B/op | 2 allocs/op |
| lion | 2702 ns/op | 4074 B/op | 38 allocs/op |
| go-kit | 3378 ns/op | 3046 B/op | 52 allocs/op |
| logrus | 4309 ns/op | 4564 B/op | 63 allocs/op |
| apex/log | 13456 ns/op | 2898 B/op | 51 allocs/op |
| log15 | 14179 ns/op | 2642 B/op | 44 allocs/op |
Log a static string, without any context or `printf`-style templating:
| Library | Time | Bytes Allocated | Objects Allocated |
| :--- | :---: | :---: | :---: |
| zerolog | 50 ns/op | 0 B/op | 0 allocs/op |
| :zap: zap | 236 ns/op | 0 B/op | 0 allocs/op |
| standard library | 453 ns/op | 80 B/op | 2 allocs/op |
| :zap: zap (sugared) | 337 ns/op | 80 B/op | 2 allocs/op |
| go-kit | 508 ns/op | 656 B/op | 13 allocs/op |
| lion | 771 ns/op | 1224 B/op | 10 allocs/op |
| logrus | 1244 ns/op | 1505 B/op | 27 allocs/op |
| apex/log | 2751 ns/op | 584 B/op | 11 allocs/op |
| log15 | 5181 ns/op | 1592 B/op | 26 allocs/op |
## Caveats
Note that zerolog does no de-duplication of fields. Using the same key multiple times creates multiple keys in final JSON:
```go
logger := zerolog.New(os.Stderr).With().Timestamp().Logger()
logger.Info().
Timestamp().
Msg("dup")
// Output: {"level":"info","time":1494567715,"time":1494567715,"message":"dup"}
```
In this case, many consumers will take the last value, but this is not guaranteed; check yours if in doubt.

## Reference:
CBOR Encoding is described in [RFC7049](https://tools.ietf.org/html/rfc7049)
## Comparison of JSON vs CBOR
Two main areas of reduction are:
1. CPU usage to write a log msg
2. Size (in bytes) of log messages.
CPU Usage savings are below:

```
Log message size savings is greatly dependent on the number and type of fields in the log message.
Assuming this log message (with an Integer, timestamp and string, in addition to level).
`{"level":"error","Fault":41650,"time":"2018-04-01T15:18:19-07:00","message":"Some Message"}`
Two measurements were done for the log file sizes - one without any compression, second
using [compress/zlib](https://golang.org/pkg/compress/zlib/).
Results for 10,000 log messages:
| Log Format | Plain File Size (in KB) | Compressed File Size (in KB) |
| :--- | :---: | :---: |
| JSON | 920 | 28 |
| CBOR | 550 | 28 |
The example used to calculate the above data is available in [Examples](examples).

If you are using the generator you can create a completion command by running
```bash

```

Writing the shell script to stdout allows the most flexible use.
```go
// completionCmd represents the completion command
var completionCmd = &cobra.Command{
Use: "completion",
Short: "Generates bash completion scripts",
Long: `To load completion run

# ~/.bashrc or ~/.profile
. <(bitbucket completion)
`,
Run: func(cmd *cobra.Command, args []string) {
rootCmd.GenBashCompletion(os.Stdout);
},
}
```
**Note:** The cobra generator may include messages printed to stdout for example if the config file is loaded, this will break the auto complete script
## Example from kubectl
Generating bash completions from a cobra command is incredibly easy. An actual program which does so for the kubernetes kubectl binary is as follows:

`out.sh` will get you completions of subcommands and flags. Copy it to `/etc/bash_completion.d/` as described [here](https://debian-administration.org/article/316/An_introduction_to_bash_completion_part_1) and reset your terminal to use autocompletion. If you make additional annotations to your code, you can get even more intelligent and flexible behavior.
## Creating your own custom functions
## Have the completions code complete your 'nouns'
### Static completion of nouns
This method allows you to provide a pre-defined list of completion choices for your nouns using the `validArgs` field.
For example, if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them. Simplified code from `kubectl get` looks like:
```go
validArgs []string = { "pod", "node", "service", "replicationcontroller" }
cmd := &cobra.Command{
Use: "get [(-o|--output=)json|yaml|template|...] (RESOURCE [NAME] | RESOURCE/NAME ...)",
Short: "Display one or many resources",
Long: get_long,
Example: get_example,
Run: func(cmd *cobra.Command, args []string) {
err := RunGet(f, out, cmd, args)
util.CheckErr(err)
},
ValidArgs: validArgs,
}
```
Notice we put the "ValidArgs" on the "get" subcommand. Doing so will give results like
```bash
# kubectl get [tab][tab]
node pod replicationcontroller service
```
### Plural form and shortcuts for nouns
If your nouns have a number of aliases, you can define them alongside `ValidArgs` using `ArgAliases`:
```go
argAliases []string = { "pods", "nodes", "services", "svc", "replicationcontrollers", "rc" }
cmd := &cobra.Command{
...
ValidArgs: validArgs,
ArgAliases: argAliases
}
```
The aliases are not shown to the user on tab completion, but they are accepted as valid nouns by
the completion algorithm if entered manually, e.g. in:
```bash
# kubectl get rc [tab][tab]
backend frontend database
```
Note that without declaring `rc` as an alias, the completion algorithm would show the list of nouns
in this example again instead of the replication controllers.
### Dynamic completion of nouns
In some cases it is not possible to provide a list of possible completions in advance. Instead, the list of completions must be determined at execution-time. Cobra provides two ways of defining such dynamic completion of nouns. Note that both these methods can be used along-side each other as long as they are not both used for the same command.
**Note**: *Custom Completions written in Go* will automatically work for other shell-completion scripts (e.g., Fish shell), while *Custom Completions written in Bash* will only work for Bash shell-completion. It is therefore recommended to use *Custom Completions written in Go*.
#### 1. Custom completions of nouns written in Go
In a similar fashion as for static completions, you can use the `ValidArgsFunction` field to provide a Go function that Cobra will execute when it needs the list of completion choices for the nouns of a command. Note that either `ValidArgs` or `ValidArgsFunction` can be used for a single cobra command, but not both.
Simplified code from `helm status` looks like:
```go
cmd := &cobra.Command{
Use: "status RELEASE_NAME",
Short: "Display the status of the named release",
Long: status_long,
RunE: func(cmd *cobra.Command, args []string) {
RunGet(args[0])
},
ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
if len(args) != 0 {
return nil, cobra.ShellCompDirectiveNoFileComp
}
return getReleasesFromCluster(toComplete), cobra.ShellCompDirectiveNoFileComp
},
}
```
Where `getReleasesFromCluster()` is a Go function that obtains the list of current Helm releases running on the Kubernetes cluster.
Notice we put the `ValidArgsFunction` on the `status` subcommand. Let's assume the Helm releases on the cluster are: `harbor`, `notary`, `rook` and `thanos` then this dynamic completion will give results like
```bash
# helm status [tab][tab]
harbor notary rook thanos
```
You may have noticed the use of `cobra.ShellCompDirective`. These directives are bit fields allowing to control some shell completion behaviors for your particular completion. You can combine them with the bit-or operator such as `cobra.ShellCompDirectiveNoSpace | cobra.ShellCompDirectiveNoFileComp`
```go
// Indicates an error occurred and completions should be ignored.
ShellCompDirectiveError
// Indicates that the shell should not add a space after the completion,
// even if there is a single completion provided.
ShellCompDirectiveNoSpace
// Indicates that the shell should not provide file completion even when
// no completion is provided.
// This currently does not work for zsh or bash < 4
ShellCompDirectiveNoFileComp
// Indicates that the shell will perform its default behavior after completions
// have been provided (this implies !ShellCompDirectiveNoSpace && !ShellCompDirectiveNoFileComp).
ShellCompDirectiveDefault
```
When using the `ValidArgsFunction`, Cobra will call your registered function after having parsed all flags and arguments provided in the command-line. You therefore don't need to do this parsing yourself. For example, when a user calls `helm status --namespace my-rook-ns [tab][tab]`, Cobra will call your registered `ValidArgsFunction` after having parsed the `--namespace` flag, as it would have done when calling the `RunE` function.
##### Debugging
Cobra achieves dynamic completions written in Go through the use of a hidden command called by the completion script. To debug your Go completion code, you can call this hidden command directly:
```bash
# helm __complete status har<ENTER>
harbor
:4
Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
```
***Important:*** If the noun to complete is empty, you must pass an empty parameter to the `__complete` command:
```bash
# helm __complete status ""<ENTER>
harbor
notary
rook
thanos
:4
Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
```
Calling the `__complete` command directly allows you to run the Go debugger to troubleshoot your code. You can also add printouts to your code; Cobra provides the following functions to use for printouts in Go completion code:
```go
// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
// is set to a file path) and optionally prints to stderr.
cobra.CompDebug(msg string, printToStdErr bool) {
cobra.CompDebugln(msg string, printToStdErr bool)
// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
// is set to a file path) and to stderr.
cobra.CompError(msg string)
cobra.CompErrorln(msg string)
```
***Important:*** You should **not** leave traces that print to stdout in your completion code as they will be interpreted as completion choices by the completion script. Instead, use the cobra-provided debugging traces functions mentioned above.
#### 2. Custom completions of nouns written in Bash
This method allows you to inject bash functions into the completion script. Those bash functions are responsible for providing the completion choices for your own completions.

# Specify custom flag completion
Similar to the filename completion and filtering using cobra.BashCompFilenameExt, you can specify
a custom flag completion function with cobra.BashCompCustom:
As for nouns, Cobra provides two ways of defining dynamic completion of flags. Note that both these methods can be used along-side each other as long as they are not both used for the same flag.
**Note**: *Custom Completions written in Go* will automatically work for other shell-completion scripts (e.g., Fish shell), while *Custom Completions written in Bash* will only work for Bash shell-completion. It is therefore recommended to use *Custom Completions written in Go*.
## 1. Custom completions of flags written in Go
To provide a Go function that Cobra will execute when it needs the list of completion choices for a flag, you must register the function in the following manner:
```go
flagName := "output"
cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
return []string{"json", "table", "yaml"}, cobra.ShellCompDirectiveDefault
})
```
Notice that calling `RegisterFlagCompletionFunc()` is done through the `command` with which the flag is associated. In our example this dynamic completion will give results like so:
```bash
# helm status --output [tab][tab]
json table yaml
```
### Debugging
You can also easily debug your Go completion code for flags:
```bash
# helm __complete status --output ""
json
table
yaml
:4
Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
```
***Important:*** You should **not** leave traces that print to stdout in your completion code as they will be interpreted as completion choices by the completion script. Instead, use the cobra-provided debugging traces functions mentioned in the above section.
## 2. Custom completions of flags written in Bash
Alternatively, you can use bash code for flag custom completion. Similar to the filename
completion and filtering using `cobra.BashCompFilenameExt`, you can specify
a custom flag completion bash function with `cobra.BashCompCustom`:

## Generating Fish Completions for your own cobra.Command
Cobra supports native Fish completions generated from the root `cobra.Command`. You can use the `command.GenFishCompletion()` or `command.GenFishCompletionFile()` functions. You must provide these functions with a parameter indicating if the completions should be annotated with a description; Cobra will provide the description automatically based on usage information. You can choose to make this option configurable by your users.
### Limitations
* Custom completions implemented using the `ValidArgsFunction` and `RegisterFlagCompletionFunc()` are supported automatically but the ones implemented in Bash scripting are not.

# Generating PowerShell Completions For Your Own cobra.Command
Cobra can generate PowerShell completion scripts. Users need PowerShell version 5.0 or above, which comes with Windows 10 and can be downloaded separately for Windows 7 or 8.1. They can then write the completions to a file and source this file from their PowerShell profile, which is referenced by the `$Profile` environment variable. See `Get-Help about_Profiles` for more info about PowerShell profiles.
# What's supported
- Completion for subcommands using their `.Short` description
- Completion for non-hidden flags using their `.Name` and `.Shorthand`
# What's not yet supported
- Command aliases
- Required, filename or custom flags (they will work like normal flags)
- Custom completion scripts

## Generating Zsh Completion for your cobra.Command
Cobra supports native Zsh completion generated from the root `cobra.Command`.
The generated completion script should be put somewhere in your `$fpath` named
`_<YOUR COMMAND>`.
### What's Supported
* Completion for all non-hidden subcommands using their `.Short` description.
* Completion for all non-hidden flags using the following rules:
* Filename completion works by marking the flag with `cmd.MarkFlagFilename...`
family of commands.
* The requirement for argument to the flag is decided by the `.NoOptDefVal`
flag value - if it's empty then completion will expect an argument.
* Flags of one of the various `*Array` and `*Slice` types supports multiple
specifications (with or without argument depending on the specific type).
* Completion of positional arguments using the following rules:
* Argument position for all options below starts at `1`. If argument position
`0` is requested it will raise an error.
* Use `command.MarkZshCompPositionalArgumentFile` to complete filenames. Glob
patterns (e.g. `"*.log"`) are optional - if not specified it will offer to
complete all file types.
* Use `command.MarkZshCompPositionalArgumentWords` to offer specific words for
completion. At least one word is required.
* It's possible to specify completion for some arguments and leave some
unspecified (e.g. offer words for second argument but nothing for first
argument). This will cause no completion for first argument but words
completion for second argument.
* If no argument completion was specified for 1st argument (but optionally was
specified for 2nd) and the command has `ValidArgs` it will be used as
completion options for 1st argument.
* Argument completions only offered for commands with no subcommands.
### What's not yet Supported
* Custom completion scripts are not supported yet (We should probably create zsh
specific one, doesn't make sense to re-use the bash one as the functions will
be different).
* Whatever other feature you're looking for and doesn't exist :)

if _, ok := err.(viper.ConfigFileNotFoundError); ok {
// Config file not found; ignore error if desired

### Writing Config Files
Reading from config files is useful, but at times you want to store all modifications made at run time.
For that, a bunch of commands are available, each with its own purpose:
* WriteConfig - writes the current viper configuration to the predefined path, if exists. Errors if no predefined path. Will overwrite the current config file, if it exists.
* SafeWriteConfig - writes the current viper configuration to the predefined path. Errors if no predefined path. Will not overwrite the current config file, if it exists.
* WriteConfigAs - writes the current viper configuration to the given filepath. Will overwrite the given file, if it exists.
* SafeWriteConfigAs - writes the current viper configuration to the given filepath. Will not overwrite the given file, if it exists.
As a rule of the thumb, everything marked with safe won't overwrite any file, but just create if not existent, whilst the default behavior is to create or truncate.

```go
viper.WriteConfig() // writes current config to predefined path set by 'viper.AddConfigPath()' and 'viper.SetConfigName'

## Q & A
Q: Why not INI files?
A: Ini files are pretty awful. There’s no standard format, and they are hard to
validate. Viper is designed to work with JSON, TOML or YAML files. If someone
really wants to add this feature, I’d be happy to merge it. It’s easy to specify
which formats your application will permit.
Q: Why is it called “Viper”?
A: Viper is designed to be a [companion](http://en.wikipedia.org/wiki/Viper_(G.I._Joe))
