# Go's `text/template` package with newline elision
This is a fork of Go 1.4's [text/template](http://golang.org/pkg/text/template/) package with one addition: a backslash immediately after a closing delimiter will delete all subsequent newlines until a non-newline.
eg.
```
{{if true}}\
hello
{{end}}\
```
Will result in:
```
hello\n
```
Rather than:
```
\n
hello\n
\n
```

Package template implements data-driven templates for generating textual output.
To generate HTML output, see package html/template, which has the same interface
as this package but automatically secures HTML output against certain attacks.
Templates are executed by applying them to a data structure. Annotations in the
template refer to elements of the data structure (typically a field of a struct
or a key in a map) to control execution and derive values to be displayed.
Execution of the template walks the structure and sets the cursor, represented
by a period '.' and called "dot", to the value at the current location in the
structure as execution proceeds.
The input text for a template is UTF-8-encoded text in any format.
"Actions"--data evaluations or control structures--are delimited by
"{{" and "}}"; all text outside actions is copied to the output unchanged.
Actions may not span newlines, although comments can.
Once parsed, a template may be executed safely in parallel.
Here is a trivial example that prints "17 items are made of wool".
type Inventory struct {
Material string
Count uint
}
sweaters := Inventory{"wool", 17}
tmpl, err := template.New("test").Parse("{{.Count}} items are made of {{.Material}}")
if err != nil { panic(err) }
err = tmpl.Execute(os.Stdout, sweaters)
if err != nil { panic(err) }
More intricate examples appear below.
Actions
Here is the list of actions. "Arguments" and "pipelines" are evaluations of
data, defined in detail below.
*/
// {{/* a comment */}}
// A comment; discarded. May contain newlines.
// Comments do not nest and must start and end at the
// delimiters, as shown here.
/*
{{pipeline}}
The default textual representation of the value of the pipeline
is copied to the output.
{{if pipeline}} T1 {{end}}
If the value of the pipeline is empty, no output is generated;
otherwise, T1 is executed. The empty values are false, 0, any
nil pointer or interface value, and any array, slice, map, or
string of length zero.
Dot is unaffected.
{{if pipeline}} T1 {{else}} T0 {{end}}
If the value of the pipeline is empty, T0 is executed;
otherwise, T1 is executed. Dot is unaffected.
{{if pipeline}} T1 {{else if pipeline}} T0 {{end}}
To simplify the appearance of if-else chains, the else action
of an if may include another if directly; the effect is exactly
the same as writing
{{if pipeline}} T1 {{else}}{{if pipeline}} T0 {{end}}{{end}}
{{range pipeline}} T1 {{end}}
The value of the pipeline must be an array, slice, map, or channel.
If the value of the pipeline has length zero, nothing is output;
otherwise, dot is set to the successive elements of the array,
slice, or map and T1 is executed. If the value is a map and the
keys are of basic type with a defined order ("comparable"), the
elements will be visited in sorted key order.
{{range pipeline}} T1 {{else}} T0 {{end}}
The value of the pipeline must be an array, slice, map, or channel.
If the value of the pipeline has length zero, dot is unaffected and
T0 is executed; otherwise, dot is set to the successive elements
of the array, slice, or map and T1 is executed.
{{template "name"}}
The template with the specified name is executed with nil data.
{{template "name" pipeline}}
The template with the specified name is executed with dot set
to the value of the pipeline.
{{with pipeline}} T1 {{end}}
If the value of the pipeline is empty, no output is generated;
otherwise, dot is set to the value of the pipeline and T1 is
executed.
{{with pipeline}} T1 {{else}} T0 {{end}}
If the value of the pipeline is empty, dot is unaffected and T0
is executed; otherwise, dot is set to the value of the pipeline
and T1 is executed.
Arguments
An argument is a simple value, denoted by one of the following.
- A boolean, string, character, integer, floating-point, imaginary
or complex constant in Go syntax. These behave like Go's untyped
constants, although raw strings may not span newlines.
- The keyword nil, representing an untyped Go nil.
- The character '.' (period):
.
The result is the value of dot.
- A variable name, which is a (possibly empty) alphanumeric string
preceded by a dollar sign, such as
$piOver2
or
$
The result is the value of the variable.
Variables are described below.
- The name of a field of the data, which must be a struct, preceded
by a period, such as
.Field
The result is the value of the field. Field invocations may be
chained:
.Field1.Field2
Fields can also be evaluated on variables, including chaining:
$x.Field1.Field2
- The name of a key of the data, which must be a map, preceded
by a period, such as
.Key
The result is the map element value indexed by the key.
Key invocations may be chained and combined with fields to any
depth:
.Field1.Key1.Field2.Key2
Although the key must be an alphanumeric identifier, unlike with
field names they do not need to start with an upper case letter.
Keys can also be evaluated on variables, including chaining:
$x.key1.key2
- The name of a niladic method of the data, preceded by a period,
such as
.Method
The result is the value of invoking the method with dot as the
receiver, dot.Method(). Such a method must have one return value (of
any type) or two return values, the second of which is an error.
If it has two and the returned error is non-nil, execution terminates
and an error is returned to the caller as the value of Execute.
Method invocations may be chained and combined with fields and keys
to any depth:
.Field1.Key1.Method1.Field2.Key2.Method2
Methods can also be evaluated on variables, including chaining:
$x.Method1.Field
- The name of a niladic function, such as
fun
The result is the value of invoking the function, fun(). The return
types and values behave as in methods. Functions and function
names are described below.
- A parenthesized instance of one the above, for grouping. The result
may be accessed by a field or map key invocation.
print (.F1 arg1) (.F2 arg2)
(.StructValuedMethod "arg").Field
Arguments may evaluate to any type; if they are pointers the implementation
automatically indirects to the base type when required.
If an evaluation yields a function value, such as a function-valued
field of a struct, the function is not invoked automatically, but it
can be used as a truth value for an if action and the like. To invoke
it, use the call function, defined below.
A pipeline is a possibly chained sequence of "commands". A command is a simple
value (argument) or a function or method call, possibly with multiple arguments:
Argument
The result is the value of evaluating the argument.
.Method [Argument...]
The method can be alone or the last element of a chain but,
unlike methods in the middle of a chain, it can take arguments.
The result is the value of calling the method with the
arguments:
dot.Method(Argument1, etc.)
functionName [Argument...]
The result is the value of calling the function associated
with the name:
function(Argument1, etc.)
Functions and function names are described below.
Pipelines
A pipeline may be "chained" by separating a sequence of commands with pipeline
characters '|'. In a chained pipeline, the result of the each command is
passed as the last argument of the following command. The output of the final
command in the pipeline is the value of the pipeline.
The output of a command will be either one value or two values, the second of
which has type error. If that second value is present and evaluates to
non-nil, execution terminates and the error is returned to the caller of
Execute.
Variables
A pipeline inside an action may initialize a variable to capture the result.
The initialization has syntax
$variable := pipeline
where $variable is the name of the variable. An action that declares a
variable produces no output.
If a "range" action initializes a variable, the variable is set to the
successive elements of the iteration. Also, a "range" may declare two
variables, separated by a comma:
range $index, $element := pipeline
in which case $index and $element are set to the successive values of the
array/slice index or map key and element, respectively. Note that if there is
only one variable, it is assigned the element; this is opposite to the
convention in Go range clauses.
A variable's scope extends to the "end" action of the control structure ("if",
"with", or "range") in which it is declared, or to the end of the template if
there is no such control structure. A template invocation does not inherit
variables from the point of its invocation.
When execution begins, $ is set to the data argument passed to Execute, that is,
to the starting value of dot.
Examples
Here are some example one-line templates demonstrating pipelines and variables.

Functions
During execution functions are found in two function maps: first in the
template, then in the global function map. By default, no functions are defined
in the template but the Funcs method can be used to add them.
Predefined global functions are named as follows.
and
Returns the boolean AND of its arguments by returning the
first empty argument or the last argument, that is,
"and x y" behaves as "if x then y else x". All the
arguments are evaluated.
call
Returns the result of calling the first argument, which
must be a function, with the remaining arguments as parameters.
Thus "call .X.Y 1 2" is, in Go notation, dot.X.Y(1, 2) where
Y is a func-valued field, map entry, or the like.
The first argument must be the result of an evaluation
that yields a value of function type (as distinct from
a predefined function such as print). The function must
return either one or two result values, the second of which
is of type error. If the arguments don't match the function
or the returned error value is non-nil, execution stops.
html
Returns the escaped HTML equivalent of the textual
representation of its arguments.
index
Returns the result of indexing its first argument by the
following arguments. Thus "index x 1 2 3" is, in Go syntax,
x[1][2][3]. Each indexed item must be a map, slice, or array.
js
Returns the escaped JavaScript equivalent of the textual
representation of its arguments.
len
Returns the integer length of its argument.
not
Returns the boolean negation of its single argument.
or
Returns the boolean OR of its arguments by returning the
first non-empty argument or the last argument, that is,
"or x y" behaves as "if x then x else y". All the
arguments are evaluated.
print
An alias for fmt.Sprint
printf
An alias for fmt.Sprintf
println
An alias for fmt.Sprintln
urlquery
Returns the escaped value of the textual representation of
its arguments in a form suitable for embedding in a URL query.
The boolean functions take any zero value to be false and a non-zero
value to be true.
There is also a set of binary comparison operators defined as
functions:
eq
Returns the boolean truth of arg1 == arg2
ne
Returns the boolean truth of arg1 != arg2
lt
Returns the boolean truth of arg1 < arg2
le
Returns the boolean truth of arg1 <= arg2
gt
Returns the boolean truth of arg1 > arg2
ge
Returns the boolean truth of arg1 >= arg2
For simpler multi-way equality tests, eq (only) accepts two or more
arguments and compares the second and subsequent to the first,
returning in effect
arg1==arg2 || arg1==arg3 || arg1==arg4 ...
(Unlike with || in Go, however, eq is a function call and all the
arguments will be evaluated.)
The comparison functions work on basic types only (or named basic
types, such as "type Celsius float32"). They implement the Go rules
for comparison of values, except that size and exact type are
ignored, so any integer value, signed or unsigned, may be compared
with any other integer value. (The arithmetic value is compared,
not the bit pattern, so all negative integers are less than all
unsigned integers.) However, as usual, one may not compare an int
with a float32 and so on.
Associated templates
Each template is named by a string specified when it is created. Also, each
template is associated with zero or more other templates that it may invoke by
name; such associations are transitive and form a name space of templates.
A template may use a template invocation to instantiate another associated
template; see the explanation of the "template" action above. The name must be
that of a template associated with the template that contains the invocation.
Nested template definitions
When parsing a template, another template may be defined and associated with the
template being parsed. Template definitions must appear at the top level of the
template, much like global variables in a Go program.
The syntax of such definitions is to surround each template declaration with a
"define" and "end" action.
The define action names the template being created by providing a string
constant. Here is a simple example:
`{{define "T1"}}ONE{{end}}
{{define "T2"}}TWO{{end}}
{{define "T3"}}{{template "T1"}} {{template "T2"}}{{end}}
{{template "T3"}}`
This defines two templates, T1 and T2, and a third T3 that invokes the other two
when it is executed. Finally it invokes T3. If executed this template will
produce the text
ONE TWO
By construction, a template may reside in only one association. If it's
necessary to have a template addressable from multiple associations, the
template definition must be parsed multiple times to create distinct *Template
values, or must be copied with the Clone or AddParseTree method.
Parse may be called multiple times to assemble the various associated templates;
see the ParseFiles and ParseGlob functions and methods for simple ways to parse
related templates stored in files.
A template may be executed directly or through ExecuteTemplate, which executes
an associated template identified by name. To invoke our example above, we
might write,
err := tmpl.Execute(os.Stdout, "no data needed")
if err != nil {
log.Fatalf("execution failed: %s", err)
}
or to invoke a particular template explicitly by name,
err := tmpl.ExecuteTemplate(os.Stdout, "T2", "no data needed")
if err != nil {
log.Fatalf("execution failed: %s", err)
}

# YAML marshaling and unmarshaling support for Go
[![Build Status](https://travis-ci.org/ghodss/yaml.svg)](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"}
*/
}
```

# errors [![Travis-CI](https://travis-ci.org/pkg/errors.svg)](https://travis-ci.org/pkg/errors) [![AppVeyor](https://ci.appveyor.com/api/projects/status/b98mptawhudj53ep/branch/master?svg=true)](https://ci.appveyor.com/project/davecheney/errors/branch/master) [![GoDoc](https://godoc.org/github.com/pkg/errors?status.svg)](http://godoc.org/github.com/pkg/errors) [![Report card](https://goreportcard.com/badge/github.com/pkg/errors)](https://goreportcard.com/report/github.com/pkg/errors)
Package errors provides simple error handling primitives.
`go get github.com/pkg/errors`
The traditional error handling idiom in Go is roughly akin to
```go
if err != nil {
return err
}
```
which applied recursively up the call stack results in error reports without context or debugging information. The errors package allows programmers to add context to the failure path in their code in a way that does not destroy the original value of the error.
## Adding context to an error
The errors.Wrap function returns a new error that adds context to the original error. For example
```go
_, err := ioutil.ReadAll(r)
if err != nil {
return errors.Wrap(err, "read failed")
}
```
## Retrieving the cause of an error
Using `errors.Wrap` constructs a stack of errors, adding context to the preceding error. Depending on the nature of the error it may be necessary to reverse the operation of errors.Wrap to retrieve the original error for inspection. Any error value which implements this interface can be inspected by `errors.Cause`.
```go
type causer interface {
Cause() error
}
```
`errors.Cause` will recursively retrieve the topmost error which does not implement `causer`, which is assumed to be the original cause. For example:
```go
switch err := errors.Cause(err).(type) {
case *MyError:
// handle specifically
default:
// unknown error
}
```

//
// can be inspected by errors.Cause. errors.Cause will recursively retrieve
// the topmost error which does not implement causer, which is assumed to be
// the original cause. For example:
//
// switch err := errors.Cause(err).(type) {
// case *MyError:
// // handle specifically
// default:
// // unknown error
// }
//
// causer interface is not exported by this package, but is considered a part
// of stable public API.
//
// Formatted printing of errors
//
// All error values returned from this package implement fmt.Formatter and can
// be formatted by the fmt package. The following verbs are supported
//
// %s print the error. If the error has a Cause it will be
// printed recursively
// %v see %s
// %+v extended format. Each Frame of the error's StackTrace will
// be printed in detail.
//
// Retrieving the stack trace of an error or wrapper
//
// New, Errorf, Wrap, and Wrapf record a stack trace at the point they are
// invoked. This information can be retrieved with the following interface.
//
// type stackTracer interface {
// StackTrace() errors.StackTrace
// }
//
// Where errors.StackTrace is defined as
//
// type StackTrace []Frame
//
// The Frame type represents a call site in the stack trace. Frame supports
// the fmt.Formatter interface that can be used for printing information about
// the stack trace of this error. For example:
//
// if err, ok := err.(stackTracer); ok {
// for _, f := range err.StackTrace() {
// fmt.Printf("%+s:%d", f)
// }
// }
//
// stackTracer interface is not exported by this package, but is considered a part
// of stable public API.
//
// See the documentation for Frame.Format for more details.

# echo-swagger
echo middleware to automatically generate RESTful API documentation with Swagger 2.0.
[![Travis branch](https://img.shields.io/travis/swaggo/echo-swagger/master.svg)](https://travis-ci.org/swaggo/echo-swagger)
[![Codecov branch](https://img.shields.io/codecov/c/github/swaggo/echo-swagger/master.svg)](https://codecov.io/gh/swaggo/echo-swagger)
[![Go Report Card](https://goreportcard.com/badge/github.com/swaggo/echo-swagger)](https://goreportcard.com/report/github.com/swaggo/echo-swagger)
## Usage
### Start using it
1. Add comments to your API source code, [See Declarative Comments Format](https://github.com/swaggo/swag#declarative-comments-format).
2. Download [Swag](https://github.com/swaggo/swag) for Go by using:
```sh
$ go get github.com/swaggo/swag/cmd/swag
```
3. Run the [Swag](https://github.com/swaggo/swag) in your Go project root folder which contains `main.go` file, [Swag](https://github.com/swaggo/swag) will parse comments and generate required files(`docs` folder and `docs/doc.go`).
```sh
$ swag init
```
4.Download [echo-swagger](https://github.com/swaggo/echo-swagger) by using:
```sh
$ go get -u github.com/swaggo/echo-swagger
```
And import following in your code:
```go
import "github.com/swaggo/echo-swagger" // echo-swagger middleware
```
### Canonical example:
```go
package main
import (
"github.com/labstack/echo"
"github.com/swaggo/echo-swagger"
_ "github.com/swaggo/echo-swagger/example/docs" // docs is generated by Swag CLI, you have to import it.
)
// @title Swagger Example API
// @version 1.0
// @description This is a sample server Petstore server.
// @termsOfService http://swagger.io/terms/
// @contact.name API Support
// @contact.url http://www.swagger.io/support
// @contact.email support@swagger.io
// @license.name Apache 2.0
// @license.url http://www.apache.org/licenses/LICENSE-2.0.html
// @host petstore.swagger.io
// @BasePath /v2
func main() {
e := echo.New()
e.GET("/swagger/*", echoSwagger.WrapHandler)
e.Logger.Fatal(e.Start(":1323"))
}
```
5. Run it, and browser to http://localhost:1323/swagger/index.html, you can see Swagger 2.0 Api documents.
