Easy and safe casting from one type to another in Go
Don’t Panic! ... Cast
## What is Cast?
Cast is a library to convert between different go types in a consistent and easy way.
Cast provides simple functions to easily convert a number to a string, an
interface into a bool, etc. Cast does this intelligently when an obvious
conversion is possible. It doesn’t make any attempts to guess what you meant,
for example you can only convert a string to an int when it is a string
representation of an int such as “8”. Cast was developed for use in
[Hugo](http://hugo.spf13.com), a website engine which uses YAML, TOML or JSON
for meta data.
## Why use Cast?
When working with dynamic data in Go you often need to cast or convert the data
from one type into another. Cast goes beyond just using type assertion (though
it uses that when possible) to provide a very straightforward and convenient
library.
If you are working with interfaces to handle things like dynamic content
you’ll need an easy way to convert an interface into a given type. This
is the library for you.
If you are taking in data from YAML, TOML or JSON or other formats which lack
full types, then Cast is the library for you.
## Usage
Cast provides a handful of To_____ methods. These methods will always return
the desired type. **If input is provided that will not convert to that type, the
0 or nil value for that type will be returned**.
Cast also provides identical methods To_____E. These return the same result as
the To_____ methods, plus an additional error which tells you if it successfully
converted. Using these methods you can tell the difference between when the
input matched the zero value or when the conversion failed and the zero value
was returned.
The following examples are merely a sample of what is available. Please review
the code for a complete set.
### Example ‘ToString’:
cast.ToString("mayonegg") // "mayonegg"
cast.ToString(8) // "8"
cast.ToString(8.31) // "8.31"
cast.ToString([]byte("one time")) // "one time"
cast.ToString(nil) // ""
var foo interface{} = "one more time"
cast.ToString(foo) // "one more time"
### Example ‘ToInt’:
cast.ToInt(8) // 8
cast.ToInt(8.31) // 8
cast.ToInt("8") // 8
cast.ToInt(true) // 1
cast.ToInt(false) // 0
var eight interface{} = 8

## Description
pflag is a drop-in replacement for Go's flag package, implementing
POSIX/GNU-style --flags.
pflag is compatible with the [GNU extensions to the POSIX recommendations
for command-line options][1]. For a more precise description, see the
"Command-line flag syntax" section below.
[1]: http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
pflag is available under the same style of BSD license as the Go language,
which can be found in the LICENSE file.
## Installation
pflag is available using the standard `go get` command.
Install by running:
go get github.com/spf13/pflag
Run tests by running:
go test github.com/spf13/pflag
## Usage
pflag is a drop-in replacement of Go's native flag package. If you import
pflag under the name "flag" then all code should continue to function
with no changes.
``` go
import flag "github.com/spf13/pflag"
```
There is one exception to this: if you directly instantiate the Flag struct
there is one more field "Shorthand" that you will need to set.
Most code never instantiates this struct directly, and instead uses
functions such as String(), BoolVar(), and Var(), and is therefore
unaffected.
Define flags using flag.String(), Bool(), Int(), etc.
This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
``` go
var ip *int = flag.Int("flagname", 1234, "help message for flagname")
```
If you like, you can bind the flag to a variable using the Var() functions.
``` go
var flagvar int
func init() {
flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
}
```
Or you can create custom flags that satisfy the Value interface (with
pointer receivers) and couple them to flag parsing by
``` go
flag.Var(&flagVal, "name", "help message for flagname")
```
For such flags, the default value is just the initial value of the variable.
After all flags are defined, call
``` go
flag.Parse()
```
to parse the command line into the defined flags.
Flags may then be used directly. If you're using the flags themselves,
they are all pointers; if you bind to variables, they're values.
``` go
fmt.Println("ip has value ", *ip)
fmt.Println("flagvar has value ", flagvar)
```
There are helper functions available to get the value stored in a Flag if you have a FlagSet but find
it difficult to keep up with all of the pointers in your code.
If you have a pflag.FlagSet with a flag called 'flagname' of type int you
can use GetInt() to get the int value. But notice that 'flagname' must exist
and it must be an int. GetString("flagname") will fail.
``` go
i, err := flagset.GetInt("flagname")
```
After parsing, the arguments after the flag are available as the
slice flag.Args() or individually as flag.Arg(i).
The arguments are indexed from 0 through flag.NArg()-1.
The pflag package also defines some new functions that are not in flag,
that give one-letter shorthands for flags. You can use these by appending
'P' to the name of any function that defines a flag.
``` go
var ip = flag.IntP("flagname", "f", 1234, "help message")
var flagvar bool
func init() {
flag.BoolVarP(&flagvar, "boolname", "b", true, "help message")
}
flag.VarP(&flagVal, "varname", "v", "help message")
```
Shorthand letters can be used with single dashes on the command line.
Boolean shorthand flags can be combined with other shorthand flags.
The default set of command-line flags is controlled by
top-level functions. The FlagSet type allows one to define
independent sets of flags, such as to implement subcommands
in a command-line interface. The methods of FlagSet are
analogous to the top-level functions for the command-line
flag set.
## Setting no option default values for flags
After you create a flag it is possible to set the pflag.NoOptDefVal for
the given flag. Doing this changes the meaning of the flag slightly. If
a flag has a NoOptDefVal and the flag is set on the command line without
an option the flag will be set to the NoOptDefVal. For example given:
``` go
var ip = flag.IntP("flagname", "f", 1234, "help message")
flag.Lookup("flagname").NoOptDefVal = "4321"
```
Would result in something like
| Parsed Arguments | Resulting Value |
| ------------- | ------------- |
| --flagname=1357 | ip=1357 |
| --flagname | ip=4321 |
| [nothing] | ip=1234 |
## Command line flag syntax
```
--flag // boolean flags, or flags with no option default values
--flag x // only on flags without a default value
--flag=x
```
Unlike the flag package, a single dash before an option means something
different than a double dash. Single dashes signify a series of shorthand
letters for flags. All but the last shorthand letter must be boolean flags
or a flag with a default value
```
// boolean or flags where the 'no option default value' is set
-f
-f=true
-abc
but
-b true is INVALID
// non-boolean and flags without a 'no option default value'
-n 1234
-n=1234
-n1234
// mixed
-abcs "hello"
-absd="hello"
-abcs1234
```
Flag parsing stops after the terminator "--". Unlike the flag package,
flags can be interspersed with arguments anywhere on the command line
before this terminator.
Integer flags accept 1234, 0664, 0x1234 and may be negative.
Boolean flags (in their long form) accept 1, 0, t, f, true, false,
TRUE, FALSE, True, False.
Duration flags accept any input valid for time.ParseDuration.
## Mutating or "Normalizing" Flag names
It is possible to set a custom flag name 'normalization function.' It allows flag names to be mutated both when created in the code and when used on the command line to some 'normalized' form. The 'normalized' form is used for comparison. Two examples of using the custom normalization func follow.
**Example #1**: You want -, _, and . in flags to compare the same. aka --my-flag == --my_flag == --my.flag
``` go
func wordSepNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
from := []string{"-", "_"}
to := "."
for _, sep := range from {
name = strings.Replace(name, sep, to, -1)
}
return pflag.NormalizedName(name)
}
myFlagSet.SetNormalizeFunc(wordSepNormalizeFunc)
```
**Example #2**: You want to alias two flags. aka --old-flag-name == --new-flag-name
``` go
func aliasNormalizeFunc(f *pflag.FlagSet, name string) pflag.NormalizedName {
switch name {
case "old-flag-name":
name = "new-flag-name"
break
}
return pflag.NormalizedName(name)
}
myFlagSet.SetNormalizeFunc(aliasNormalizeFunc)
```
## Deprecating a flag or its shorthand
It is possible to deprecate a flag, or just its shorthand. Deprecating a flag/shorthand hides it from help text and prints a usage message when the deprecated flag/shorthand is used.
**Example #1**: You want to deprecate a flag named "badflag" as well as inform the users what flag they should use instead.
```go
// deprecate a flag by specifying its name and a usage message
flags.MarkDeprecated("badflag", "please use --good-flag instead")
```
This hides "badflag" from help text, and prints `Flag --badflag has been deprecated, please use --good-flag instead` when "badflag" is used.
**Example #2**: You want to keep a flag name "noshorthandflag" but deprecate its shortname "n".
```go
// deprecate a flag shorthand by specifying its flag name and a usage message
flags.MarkShorthandDeprecated("noshorthandflag", "please use --noshorthandflag only")
```
This hides the shortname "n" from help text, and prints `Flag shorthand -n has been deprecated, please use --noshorthandflag only` when the shorthand "n" is used.
Note that usage message is essential here, and it should not be empty.
## Hidden flags
It is possible to mark a flag as hidden, meaning it will still function as normal, however will not show up in usage/help text.
**Example**: You have a flag named "secretFlag" that you need for internal use only and don't want it showing up in help text, or for its usage text to be available.
```go
// hide a flag by specifying its name
flags.MarkHidden("secretFlag")
```
## Disable sorting of flags
`pflag` allows you to disable sorting of flags for help and usage message.
**Example**:
```go
flags.BoolP("verbose", "v", false, "verbose output")
flags.String("coolflag", "yeaah", "it's really cool flag")
flags.Int("usefulflag", 777, "sometimes it's very useful")
flags.SortFlags = false
flags.PrintDefaults()
```
**Output**:
```
-v, --verbose verbose output
--coolflag string it's really cool flag (default "yeaah")
--usefulflag int sometimes it's very useful (default 777)
```
## Supporting Go flags when using pflag
In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary
to support flags defined by third-party dependencies (e.g. `golang/glog`).
**Example**: You want to add the Go flags to the `CommandLine` flagset
```go
import (
goflag "flag"
flag "github.com/spf13/pflag"
)
var ip *int = flag.Int("flagname", 1234, "help message for flagname")
func main() {
flag.CommandLine.AddGoFlagSet(goflag.CommandLine)
flag.Parse()
}
```

Package pflag is a drop-in replacement for Go's flag package, implementing
POSIX/GNU-style --flags.
pflag is compatible with the GNU extensions to the POSIX recommendations
for command-line options. See
http://www.gnu.org/software/libc/manual/html_node/Argument-Syntax.html
Usage:
pflag is a drop-in replacement of Go's native flag package. If you import
pflag under the name "flag" then all code should continue to function
with no changes.
import flag "github.com/spf13/pflag"
There is one exception to this: if you directly instantiate the Flag struct
there is one more field "Shorthand" that you will need to set.
Most code never instantiates this struct directly, and instead uses
functions such as String(), BoolVar(), and Var(), and is therefore
unaffected.
Define flags using flag.String(), Bool(), Int(), etc.
This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
var ip = flag.Int("flagname", 1234, "help message for flagname")
If you like, you can bind the flag to a variable using the Var() functions.
var flagvar int
func init() {
flag.IntVar(&flagvar, "flagname", 1234, "help message for flagname")
}
Or you can create custom flags that satisfy the Value interface (with
pointer receivers) and couple them to flag parsing by
flag.Var(&flagVal, "name", "help message for flagname")
For such flags, the default value is just the initial value of the variable.
After all flags are defined, call
flag.Parse()
to parse the command line into the defined flags.
Flags may then be used directly. If you're using the flags themselves,
they are all pointers; if you bind to variables, they're values.
fmt.Println("ip has value ", *ip)
fmt.Println("flagvar has value ", flagvar)
After parsing, the arguments after the flag are available as the
slice flag.Args() or individually as flag.Arg(i).
The arguments are indexed from 0 through flag.NArg()-1.
The pflag package also defines some new functions that are not in flag,
that give one-letter shorthands for flags. You can use these by appending
'P' to the name of any function that defines a flag.
var ip = flag.IntP("flagname", "f", 1234, "help message")
var flagvar bool
func init() {
flag.BoolVarP(&flagvar, "boolname", "b", true, "help message")
}
flag.VarP(&flagval, "varname", "v", "help message")
Shorthand letters can be used with single dashes on the command line.
Boolean shorthand flags can be combined with other shorthand flags.
Command line flag syntax:
--flag // boolean flags only
--flag=x
Unlike the flag package, a single dash before an option means something
different than a double dash. Single dashes signify a series of shorthand
letters for flags. All but the last shorthand letter must be boolean flags.
// boolean flags
-f
-abc
// non-boolean flags
-n 1234
-Ifile
// mixed
-abcs "hello"
-abcn1234
Flag parsing stops after the terminator "--". Unlike the flag package,
flags can be interspersed with arguments anywhere on the command line
before this terminator.
Integer flags accept 1234, 0664, 0x1234 and may be negative.
Boolean flags (in their long form) accept 1, 0, t, f, true, false,
TRUE, FALSE, True, False.
Duration flags accept any input valid for time.ParseDuration.
The default set of command-line flags is controlled by
top-level functions. The FlagSet type allows one to define
independent sets of flags, such as to implement subcommands
in a command-line interface. The methods of FlagSet are
analogous to the top-level functions for the command-line
flag set.

[](https://pkg.go.dev/github.com/lib/pq?tab=doc)
## Install
go get github.com/lib/pq
## Features
* SSL
* Handles bad connections for `database/sql`
* Scan `time.Time` correctly (i.e. `timestamp[tz]`, `time[tz]`, `date`)
* Scan binary blobs correctly (i.e. `bytea`)
* Package for `hstore` support
* COPY FROM support
* pq.ParseURL for converting urls to connection strings for sql.Open.
* Many libpq compatible environment variables
* Unix socket support
* Notifications: `LISTEN`/`NOTIFY`
* pgpass support
* GSS (Kerberos) auth
## Tests
`go test` is used for testing. See [TESTS.md](TESTS.md) for more details.
## Status
This package is effectively in maintenance mode and is not actively developed. Small patches and features are only rarely reviewed and merged. We recommend using [pgx](https://github.com/jackc/pgx) which is actively maintained.

## Running Tests
`go test` is used for testing. A running PostgreSQL
server is required, with the ability to log in. The
database to connect to test with is "pqgotest," on
"localhost" but these can be overridden using [environment
variables](https://www.postgresql.org/docs/9.3/static/libpq-envars.html).
Example:
PGHOST=/run/postgresql go test
## Benchmarks
A benchmark suite can be run as part of the tests:
go test -bench .
## Example setup (Docker)
Run a postgres container:
```
docker run --expose 5432:5432 postgres
```
Run tests:
```
PGHOST=localhost PGPORT=5432 PGUSER=postgres PGSSLMODE=disable PGDATABASE=postgres go test
```

Package pq is a pure Go Postgres driver for the database/sql package.
In most cases clients will use the database/sql package instead of
using this package directly. For example:
import (
"database/sql"
_ "github.com/lib/pq"
)
func main() {
connStr := "user=pqgotest dbname=pqgotest sslmode=verify-full"
db, err := sql.Open("postgres", connStr)
if err != nil {
log.Fatal(err)
}
age := 21
rows, err := db.Query("SELECT name FROM users WHERE age = $1", age)
…
}
You can also connect to a database using a URL. For example:
connStr := "postgres://pqgotest:password@localhost/pqgotest?sslmode=verify-full"
db, err := sql.Open("postgres", connStr)
Connection String Parameters
Similarly to libpq, when establishing a connection using pq you are expected to
supply a connection string containing zero or more parameters.
A subset of the connection parameters supported by libpq are also supported by pq.
Additionally, pq also lets you specify run-time parameters (such as search_path or work_mem)
directly in the connection string. This is different from libpq, which does not allow
run-time parameters in the connection string, instead requiring you to supply
them in the options parameter.
For compatibility with libpq, the following special connection parameters are
supported:
* dbname - The name of the database to connect to
* user - The user to sign in as
* password - The user's password
* host - The host to connect to. Values that start with / are for unix
domain sockets. (default is localhost)
* port - The port to bind to. (default is 5432)
* sslmode - Whether or not to use SSL (default is require, this is not
the default for libpq)
* fallback_application_name - An application_name to fall back to if one isn't provided.
* connect_timeout - Maximum wait for connection, in seconds. Zero or
not specified means wait indefinitely.
* sslcert - Cert file location. The file must contain PEM encoded data.
* sslkey - Key file location. The file must contain PEM encoded data.
* sslrootcert - The location of the root certificate file. The file
must contain PEM encoded data.
Valid values for sslmode are:
* disable - No SSL
* require - Always SSL (skip verification)
* verify-ca - Always SSL (verify that the certificate presented by the
server was signed by a trusted CA)
* verify-full - Always SSL (verify that the certification presented by
the server was signed by a trusted CA and the server host name
matches the one in the certificate)
See http://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING
for more information about connection string parameters.
Use single quotes for values that contain whitespace:
"user=pqgotest password='with spaces'"
A backslash will escape the next character in values:
"user=space\ man password='it\'s valid'"
Note that the connection parameter client_encoding (which sets the
text encoding for the connection) may be set but must be "UTF8",
matching with the same rules as Postgres. It is an error to provide
any other value.
In addition to the parameters listed above, any run-time parameter that can be
set at backend start time can be set in the connection string. For more
information, see
http://www.postgresql.org/docs/current/static/runtime-config.html.
Most environment variables as specified at http://www.postgresql.org/docs/current/static/libpq-envars.html
supported by libpq are also supported by pq. If any of the environment
variables not supported by pq are set, pq will panic during connection
establishment. Environment variables have a lower precedence than explicitly
provided connection parameters.
The pgpass mechanism as described in http://www.postgresql.org/docs/current/static/libpq-pgpass.html
is supported, but on Windows PGPASSFILE must be specified explicitly.
Queries
database/sql does not dictate any specific format for parameter
markers in query strings, and pq uses the Postgres-native ordinal markers,
as shown above. The same marker can be reused for the same parameter:
rows, err := db.Query(`SELECT name FROM users WHERE favorite_fruit = $1
OR age BETWEEN $2 AND $2 + 3`, "orange", 64)
pq does not support the LastInsertId() method of the Result type in database/sql.
To return the identifier of an INSERT (or UPDATE or DELETE), use the Postgres
RETURNING clause with a standard Query or QueryRow call:
var userid int
err := db.QueryRow(`INSERT INTO users(name, favorite_fruit, age)
VALUES('beatrice', 'starfruit', 93) RETURNING id`).Scan(&userid)
For more details on RETURNING, see the Postgres documentation:
http://www.postgresql.org/docs/current/static/sql-insert.html
http://www.postgresql.org/docs/current/static/sql-update.html
http://www.postgresql.org/docs/current/static/sql-delete.html
For additional instructions on querying see the documentation for the database/sql package.
Data Types
Parameters pass through driver.DefaultParameterConverter before they are handled
by this package. When the binary_parameters connection option is enabled,
[]byte values are sent directly to the backend as data in binary format.
This package returns the following types for values from the PostgreSQL backend:
- integer types smallint, integer, and bigint are returned as int64
- floating-point types real and double precision are returned as float64
- character types char, varchar, and text are returned as string
- temporal types date, time, timetz, timestamp, and timestamptz are
returned as time.Time
- the boolean type is returned as bool
- the bytea type is returned as []byte
All other types are returned directly from the backend as []byte values in text format.
Errors
pq may return errors of type *pq.Error which can be interrogated for error details:
if err, ok := err.(*pq.Error); ok {
fmt.Println("pq error:", err.Code.Name())
}
See the pq.Error type for details.
Bulk imports
You can perform bulk imports by preparing a statement returned by pq.CopyIn (or
pq.CopyInSchema) in an explicit transaction (sql.Tx). The returned statement
handle can then be repeatedly "executed" to copy data into the target table.
After all data has been processed you should call Exec() once with no arguments
to flush all buffered data. Any call to Exec() might return an error which
should be handled appropriately, but because of the internal buffering an error
returned by Exec() might not be related to the data passed in the call that
failed.
CopyIn uses COPY FROM internally. It is not possible to COPY outside of an
explicit transaction in pq.
Usage example:
txn, err := db.Begin()
if err != nil {
log.Fatal(err)
}
stmt, err := txn.Prepare(pq.CopyIn("users", "name", "age"))
if err != nil {
log.Fatal(err)
}
for _, user := range users {
_, err = stmt.Exec(user.Name, int64(user.Age))
if err != nil {
log.Fatal(err)
}
}
_, err = stmt.Exec()
if err != nil {
log.Fatal(err)
}
err = stmt.Close()
if err != nil {
log.Fatal(err)
}
err = txn.Commit()
if err != nil {
log.Fatal(err)
}
Notifications
PostgreSQL supports a simple publish/subscribe model over database
connections. See http://www.postgresql.org/docs/current/static/sql-notify.html
for more information about the general mechanism.
To start listening for notifications, you first have to open a new connection
to the database by calling NewListener. This connection can not be used for
anything other than LISTEN / NOTIFY. Calling Listen will open a "notification
channel"; once a notification channel is open, a notification generated on that
channel will effect a send on the Listener.Notify channel. A notification
channel will remain open until Unlisten is called, though connection loss might
result in some notifications being lost. To solve this problem, Listener sends
a nil pointer over the Notify channel any time the connection is re-established
following a connection loss. The application can get information about the
state of the underlying connection by setting an event callback in the call to
NewListener.
A single Listener can safely be used from concurrent goroutines, which means
that there is often no need to create more than one Listener in your
application. However, a Listener is always connected to a single database, so
you will need to create a new Listener instance for every database you want to
receive notifications in.
The channel name in both Listen and Unlisten is case sensitive, and can contain
any characters legal in an identifier (see
http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS
for more information). Note that the channel name will be truncated to 63
bytes by the PostgreSQL server.
You can find a complete, working example of Listener usage at
https://godoc.org/github.com/lib/pq/example/listen.
Kerberos Support
If you need support for Kerberos authentication, add the following to your main
package:
import "github.com/lib/pq/auth/kerberos"
func init() {
pq.RegisterGSSProvider(func() (pq.Gss, error) { return kerberos.NewGSS() })
}
This package is in a separate module so that users who don't need Kerberos
don't have to download unnecessary dependencies.
When imported, additional connection string parameters are supported:
* krbsrvname - GSS (Kerberos) service name when constructing the
SPN (default is `postgres`). This will be combined with the host
to form the full SPN: `krbsrvname/host`.
* krbspn - GSS (Kerberos) SPN. This takes priority over
`krbsrvname` if present.

`flock` implements a thread-safe sync.Locker interface for file locking. It also
includes a non-blocking TryLock() function to allow locking without blocking execution.
## License
`flock` is released under the BSD 3-Clause License. See the `LICENSE` file for more details.
## Go Compatibility
This package makes use of the `context` package that was introduced in Go 1.7. As such, this
package has an implicit dependency on Go 1.7+.
## Installation
```
go get -u github.com/gofrs/flock
```
## Usage
```Go
import "github.com/gofrs/flock"
fileLock := flock.New("/var/lock/go-lock.lock")
locked, err := fileLock.TryLock()
if err != nil {
// handle locking error
}
if locked {
// do work
fileLock.Unlock()
}
```
For more detailed usage information take a look at the package API docs on
[GoDoc](https://godoc.org/github.com/gofrs/flock).

[](https://travis-ci.org/ghodss/yaml)
## Introduction
A wrapper around [go-yaml](https://github.com/go-yaml/yaml) designed to enable a better way of handling YAML when marshaling to and from structs.
In short, this library first converts YAML to JSON using go-yaml and then uses `json.Marshal` and `json.Unmarshal` to convert to or from the struct. This means that it effectively reuses the JSON struct tags as well as the custom JSON methods `MarshalJSON` and `UnmarshalJSON` unlike go-yaml. For a detailed overview of the rationale behind this method, [see this blog post](http://ghodss.com/2014/the-right-way-to-handle-yaml-in-golang/).
## Compatibility
This package uses [go-yaml](https://github.com/go-yaml/yaml) and therefore supports [everything go-yaml supports](https://github.com/go-yaml/yaml#compatibility).
## Caveats
**Caveat #1:** When using `yaml.Marshal` and `yaml.Unmarshal`, binary data should NOT be preceded with the `!!binary` YAML tag. If you do, go-yaml will convert the binary data from base64 to native binary data, which is not compatible with JSON. You can still use binary in your YAML files though - just store them without the `!!binary` tag and decode the base64 in your code (e.g. in the custom JSON methods `MarshalJSON` and `UnmarshalJSON`). This also has the benefit that your YAML and your JSON binary data will be decoded exactly the same way. As an example:
```
BAD:
exampleKey: !!binary gIGC
GOOD:
exampleKey: gIGC
... and decode the base64 data in your code.
```
**Caveat #2:** When using `YAMLToJSON` directly, maps with keys that are maps will result in an error since this is not supported by JSON. This error will occur in `Unmarshal` as well since you can't unmarshal map keys anyways since struct fields can't be keys.
## Installation and usage
To install, run:
```
$ go get github.com/ghodss/yaml
```
And import using:
```
import "github.com/ghodss/yaml"
```
Usage is very similar to the JSON library:
```go
package main
import (
"fmt"
"github.com/ghodss/yaml"
)
type Person struct {
Name string `json:"name"` // Affects YAML field names too.
Age int `json:"age"`
}
func main() {
// Marshal a Person struct to YAML.
p := Person{"John", 30}
y, err := yaml.Marshal(p)
if err != nil {
fmt.Printf("err: %v\n", err)
return
}
fmt.Println(string(y))
/* Output:
age: 30
name: John
*/
// Unmarshal the YAML back into a Person struct.
var p2 Person
err = yaml.Unmarshal(y, &p2)
if err != nil {
fmt.Printf("err: %v\n", err)
return
}
fmt.Println(p2)
/* Output:
{John 30}
*/
}
```
`yaml.YAMLToJSON` and `yaml.JSONToYAML` methods are also available:
```go
package main
import (
"fmt"
"github.com/ghodss/yaml"
)
func main() {
j := []byte(`{"name": "John", "age": 30}`)
y, err := yaml.JSONToYAML(j)
if err != nil {
fmt.Printf("err: %v\n", err)
return
}
fmt.Println(string(y))
/* Output:
name: John
age: 30
*/
j2, err := yaml.YAMLToJSON(y)
if err != nil {
fmt.Printf("err: %v\n", err)
return
}
fmt.Println(string(j2))
/* Output:
{"age":30,"name":"John"}
*/
}
```
