(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. -All produce the quoted word "output": - - {{"\"output\""}} - A string constant. - {{`"output"`}} - A raw string constant. - {{printf "%q" "output"}} - A function call. - {{"output" | printf "%q"}} - A function call whose final argument comes from the previous - command. - {{printf "%q" (print "out" "put")}} - A parenthesized argument. - {{"put" | printf "%s%s" "out" | printf "%q"}} - A more elaborate call. - {{"output" | printf "%s" | printf "%q"}} - A longer chain. - {{with "output"}}{{printf "%q" .}}{{end}} - A with action using dot. - {{with $x := "output" | printf "%q"}}{{$x}}{{end}} - A with action that creates and uses a variable. - {{with $x := "output"}}{{printf "%q" $x}}{{end}} - A with action that uses the variable in another action. - {{with $x := "output"}}{{$x | printf "%q"}}{{end}} - The same, but pipelined. - -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) - } - -*/ -package template diff --git a/src/cfdnsupdater/Godeps/_workspace/src/github.com/alecthomas/template/exec.go b/src/cfdnsupdater/Godeps/_workspace/src/github.com/alecthomas/template/exec.go deleted file mode 100644 index c3078e5..0000000 --- a/src/cfdnsupdater/Godeps/_workspace/src/github.com/alecthomas/template/exec.go +++ /dev/null @@ -1,845 +0,0 @@ -// Copyright 2011 The Go Authors.

It supports flags, nested commands, and -positional arguments. - -Install it with: - - $ go get gopkg.in/alecthomas/kingpin.v2 - -It looks like this: - -```go -var ( - verbose = kingpin.Flag("verbose", "Verbose mode.").Short('v').Bool() - name = kingpin.Arg("name", "Name of user.").Required().String() -) - -func main() { - kingpin.Parse() - fmt.Printf("%v, %s\n", *verbose, *name) -} -``` - -More [examples](https://github.com/alecthomas/kingpin/tree/master/examples) are available. - -Second to parsing, providing the user with useful help is probably the most -important thing a command-line parser does. Kingpin tries to provide detailed -contextual help if `--help` is encountered at any point in the command line -(excluding after `--`). - -## Features - -- Help output that isn't as ugly as sin. -- Fully [customisable help](#custom-help), via Go templates. -- Parsed, type-safe flags (`kingpin.Flag("f", "help").Int()`) -- Parsed, type-safe positional arguments (`kingpin.Arg("a", "help").Int()`). -- Parsed, type-safe, arbitrarily deep commands (`kingpin.Command("c", "help")`). -- Support for required flags and required positional arguments (`kingpin.Flag("f", "").Required().Int()`). -- Support for arbitrarily nested default commands (`command.Default()`). -- Callbacks per command, flag and argument (`kingpin.Command("c", "").Action(myAction)`). -- POSIX-style short flag combining (`-a -b` -> `-ab`). -- Short-flag+parameter combining (`-a parm` -> `-aparm`). -- Read command-line from files (`@`). -- Automatically generate man pages (`--man-page`). - -## User-visible changes between v1 and v2 - -### Flags can be used at any point after their definition. - -Flags can be specified at any point after their definition, not just -*immediately after their associated command*. From the chat example below, the -following used to be required: - -``` -$ chat --server=chat.server.com:8080 post --image=~/Downloads/owls.jpg pics -``` - -But the following will now work: - -``` -$ chat post --server=chat.server.com:8080 --image=~/Downloads/owls.jpg pics -``` - -### Short flags can be combined with their parameters - -Previously, if a short flag was used, any argument to that flag would have to -be separated by a space. That is no longer the case. - -## API changes between v1 and v2 - -- `ParseWithFileExpansion()` is gone. The new parser directly supports expanding `@`. -- Added `FatalUsage()` and `FatalUsageContext()` for displaying an error + usage and terminating. -- `Dispatch()` renamed to `Action()`. -- Added `ParseContext()` for parsing a command line into its intermediate context form without executing. -- Added `Terminate()` function to override the termination function. -- Added `UsageForContextWithTemplate()` for printing usage via a custom template. -- Added `UsageTemplate()` for overriding the default template to use. Two templates are included: - 1. `DefaultUsageTemplate` - default template. - 2. `CompactUsageTemplate` - compact command template for larger applications. - -## Versions - -Kingpin uses [gopkg.in](https://gopkg.in/alecthomas/kingpin) for versioning. - -The current stable version is [gopkg.in/alecthomas/kingpin.v2](https://gopkg.in/alecthomas/kingpin.v2). The previous version, [gopkg.in/alecthomas/kingpin.v1](https://gopkg.in/alecthomas/kingpin.v1), is deprecated and in maintenance mode. - -### [V2](https://gopkg.in/alecthomas/kingpin.v2) is the current stable version - -Installation: - -```sh -$ go get gopkg.in/alecthomas/kingpin.v2 -``` - -### [V1](https://gopkg.in/alecthomas/kingpin.v1) is the OLD stable version - -Installation: - -```sh -$ go get gopkg.in/alecthomas/kingpin.v1 -``` - -## Change History - -- *2015-09-19* -- Stable v2.1.0 release. - - Added `command.Default()` to specify a default command to use if no other - command matches. This allows for convenient user shortcuts. - - Exposed `HelpFlag` and `VersionFlag` for further cusomisation. - - `Action()` and `PreAction()` added and both now support an arbitrary - number of callbacks. - - `kingpin.SeparateOptionalFlagsUsageTemplate`. - - `--help-long` and `--help-man` (hidden by default) flags. - - Flags are "interspersed" by default, but can be disabled with `app.Interspersed(false)`. - - Added flags for all simple builtin types (int8, uint16, etc.) and slice variants. - - Use `app.Writer(os.Writer)` to specify the default writer for all output functions. - - Dropped `os.Writer` prefix from all printf-like functions. - -- *2015-05-22* -- Stable v2.0.0 release. - - Initial stable release of v2.0.0. - - Fully supports interspersed flags, commands and arguments. - - Flags can be present at any point after their logical definition. - - Application.Parse() terminates if commands are present and a command is not parsed. - - Dispatch() -> Action(). - - Actions are dispatched after all values are populated. - - Override termination function (defaults to os.Exit). - - Override output stream (defaults to os.Stderr). - - Templatised usage help, with default and compact templates. - - Make error/usage functions more consistent. - - Support argument expansion from files by default (with @). - - Fully public data model is available via .Model(). - - Parser has been completely refactored. - - Parsing and execution has been split into distinct stages. - - Use `go generate` to generate repeated flags. - - Support combined short-flag+argument: -fARG. - -- *2015-01-23* -- Stable v1.3.4 release. - - Support "--" for separating flags from positional arguments. - - Support loading flags from files (ParseWithFileExpansion()). Use @FILE as an argument. - - Add post-app and post-cmd validation hooks. This allows arbitrary validation to be added. - - A bunch of improvements to help usage and formatting. - - Support arbitrarily nested sub-commands. - -- *2014-07-08* -- Stable v1.2.0 release. - - Pass any value through to `Strings()` when final argument. - Allows for values that look like flags to be processed. - - Allow `--help` to be used with commands. - - Support `Hidden()` flags. - - Parser for [units.Base2Bytes](https://github.com/alecthomas/units) - type. Allows for flags like `--ram=512MB` or `--ram=1GB`. - - Add an `Enum()` value, allowing only one of a set of values - to be selected. eg. `Flag(...).Enum("debug", "info", "warning")`. - -- *2014-06-27* -- Stable v1.1.0 release. - - Bug fixes. - - Always return an error (rather than panicing) when misconfigured. - - `OpenFile(flag, perm)` value type added, for finer control over opening files. - - Significantly improved usage formatting. - -- *2014-06-19* -- Stable v1.0.0 release. - - Support [cumulative positional](#consuming-all-remaining-arguments) arguments. - - Return error rather than panic when there are fatal errors not caught by - the type system. eg. when a default value is invalid. - - Use gokpg.in. - -- *2014-06-10* -- Place-holder streamlining. - - Renamed `MetaVar` to `PlaceHolder`. - - Removed `MetaVarFromDefault`. Kingpin now uses [heuristics](#place-holders-in-help) - to determine what to display. - -## Examples - -### Simple Example - -Kingpin can be used for simple flag+arg applications like so: - -``` -$ ping --help -usage: ping [] [] - -Flags: - --debug Enable debug mode. - --help Show help. - -t, --timeout=5s Timeout waiting for ping. - -Args: - IP address to ping. - [] Number of packets to send -$ ping 1.2.3.4 5 -Would ping: 1.2.3.4 with timeout 5s and count 0 -``` - -From the following source: - -```go -package main - -import ( - "fmt" - - "gopkg.in/alecthomas/kingpin.v2" -) - -var ( - debug = kingpin.Flag("debug", "Enable debug mode.").Bool() - timeout = kingpin.Flag("timeout", "Timeout waiting for ping.").Default("5s").OverrideDefaultFromEnvar("PING_TIMEOUT").Short('t').Duration() - ip = kingpin.Arg("ip", "IP address to ping.").Required().IP() - count = kingpin.Arg("count", "Number of packets to send").Int() -) - -func main() { - kingpin.Version("0.0.1") - kingpin.Parse() - fmt.Printf("Would ping: %s with timeout %s and count %d", *ip, *timeout, *count) -} -``` - -### Complex Example - -Kingpin can also produce complex command-line applications with global flags, -subcommands, and per-subcommand flags, like this: - -``` -$ chat --help -usage: chat [] [] [ ...] - -A command-line chat application. - -Flags: - --help Show help. - --debug Enable debug mode. - --server=127.0.0.1 Server address. - -Commands: - help [] - Show help for a command. - - register - Register a new user. - - post [] [] - Post a message to a channel. - -$ chat help post -usage: chat [] post [] [] - -Post a message to a channel. - -Flags: - --image=IMAGE Image to post. - -Args: - Channel to post to. - [] Text to post. - -$ chat post --image=~/Downloads/owls.jpg pics -... -``` - -From this code: - -```go -package main - -import ( - "os" - "strings" - "gopkg.in/alecthomas/kingpin.v2" -) - -var ( - app = kingpin.New("chat", "A command-line chat application.") - debug = app.Flag("debug", "Enable debug mode.").Bool() - serverIP = app.Flag("server", "Server address.").Default("127.0.0.1").IP() - - register = app.Command("register", "Register a new user.") - registerNick = register.Arg("nick", "Nickname for user.").Required().String() - registerName = register.Arg("name", "Name of user.").Required().String() - - post = app.Command("post", "Post a message to a channel.") - postImage = post.Flag("image", "Image to post.").File() - postChannel = post.Arg("channel", "Channel to post to.").Required().String() - postText = post.Arg("text", "Text to post.").Strings() -) - -func main() { - switch kingpin.MustParse(app.Parse(os.Args[1:])) { - // Register user - case register.FullCommand(): - println(*registerNick) - - // Post message - case post.FullCommand(): - if *postImage != nil { - } - text := strings.Join(*postText, " ") - println("Post:", text) - } -} -``` - -## Reference Documentation - -### Displaying errors and usage information - -Kingpin exports a set of functions to provide consistent errors and usage -information to the user. - -Error messages look something like this: - - : error: - -The functions on `Application` are: - -Function | Purpose ----------|-------------- -`Errorf(format, args)` | Display a printf formatted error to the user. -`Fatalf(format, args)` | As with Errorf, but also call the termination handler. -`FatalUsage(format, args)` | As with Fatalf, but also print contextual usage information. -`FatalUsageContext(context, format, args)` | As with Fatalf, but also print contextual usage information from a `ParseContext`. -`FatalIfError(err, format, args)` | Conditionally print an error prefixed with format+args, then call the termination handler - -There are equivalent global functions in the kingpin namespace for the default -`kingpin.CommandLine` instance. - -### Sub-commands - -Kingpin supports nested sub-commands, with separate flag and positional -arguments per sub-command. Note that positional arguments may only occur after -sub-commands. - -For example: - -```go -var ( - deleteCommand = kingpin.Command("delete", "Delete an object.") - deleteUserCommand = deleteCommand.Command("user", "Delete a user.") - deleteUserUIDFlag = deleteUserCommand.Flag("uid", "Delete user by UID rather than username.") - deleteUserUsername = deleteUserCommand.Arg("username", "Username to delete.") - deletePostCommand = deleteCommand.Command("post", "Delete a post.") -) - -func main() { - switch kingpin.Parse() { - case "delete user": - case "delete post": - } -} -``` - -### Custom Parsers - -Kingpin supports both flag and positional argument parsers for converting to -Go types. For example, some included parsers are `Int()`, `Float()`, -`Duration()` and `ExistingFile()`. - -Parsers conform to Go's [`flag.Value`](http://godoc.org/flag#Value) -interface, so any existing implementations will work. - -For example, a parser for accumulating HTTP header values might look like this: - -```go -type HTTPHeaderValue http.Header - -func (h *HTTPHeaderValue) Set(value string) error { - parts := strings.SplitN(value, ":", 2) - if len(parts) != 2 { - return fmt.Errorf("expected HEADER:VALUE got '%s'", value) - } - (*http.Header)(h).Add(parts[0], parts[1]) - return nil -} - -func (h *HTTPHeaderValue) String() string { - return "" -} -``` - -As a convenience, I would recommend something like this: - -```go -func HTTPHeader(s Settings) (target *http.Header) { - target = new(http.Header) - s.SetValue((*HTTPHeaderValue)(target)) - return -} -``` - -You would use it like so: - -```go -headers = HTTPHeader(kingpin.Flag("header", "Add a HTTP header to the request.").Short('H')) -``` - -### Repeatable flags - -Depending on the `Value` they hold, some flags may be repeated. The -`IsCumulative() bool` function on `Value` tells if it's safe to call `Set()` -multiple times or if an error should be raised if several values are passed. - -The built-in `Value`s returning slices and maps, as well as `Counter` are -examples of `Value`s that make a flag repeatable. - -### Boolean values - -Boolean values are uniquely managed by Kingpin. Each boolean flag will have a negative complement: -`--` and `--no-`. - -### Default Values - -The default value is the zero value for a type. This can be overridden with -the `Default(value...)` function on flags and arguments. This function accepts -one or several strings, which are parsed by the value itself, so they *must* -be compliant with the format expected. - -### Place-holders in Help - -The place-holder value for a flag is the value used in the help to describe -the value of a non-boolean flag. - -The value provided to PlaceHolder() is used if provided, then the value -provided by Default() if provided, then finally the capitalised flag name is -used. - -Here are some examples of flags with various permutations: - - --name=NAME // Flag(...).String() - --name="Harry" // Flag(...).Default("Harry").String() - --name=FULL-NAME // flag(...).PlaceHolder("FULL-NAME").Default("Harry").String() - -### Consuming all remaining arguments - -A common command-line idiom is to use all remaining arguments for some -purpose. eg. The following command accepts an arbitrary number of -IP addresses as positional arguments: - - ./cmd ping 10.1.1.1 192.168.1.1 - -Such arguments are similar to [repeatable flags](#repeatable-flags), but for -arguments. Therefore they use the same `IsCumulative() bool` function on the -underlying `Value`, so the built-in `Value`s for which the `Set()` function -can be called several times will consume multiple arguments. - -To implement the above example with a custom `Value`, we might do something -like this: - -```go -type ipList []net.IP - -func (i *ipList) Set(value string) error { - if ip := net.ParseIP(value); ip == nil { - return fmt.Errorf("'%s' is not an IP address", value) - } else { - *i = append(*i, ip) - return nil - } -} - -func (i *ipList) String() string { - return "" -} - -func (i *ipList) IsCumulative() bool { - return true -} - -func IPList(s Settings) (target *[]net.IP) { - target = new([]net.IP) - s.SetValue((*ipList)(target)) - return -} -``` - -And use it like so: - -```go -ips := IPList(kingpin.Arg("ips", "IP addresses to ping.")) -``` - -### Supporting -h for help - -`kingpin.CommandLine.HelpFlag.Short('h')` - -### Custom help - -Kingpin v2 supports templatised help using the text/template library (actually, [a fork](https://github.com/alecthomas/template)). - -You can specify the template to use with the [Application.UsageTemplate()](http://godoc.org/gopkg.in/alecthomas/kingpin.v2#Application.UsageTemplate) function. - -There are four included templates: `kingpin.DefaultUsageTemplate` is the default, -`kingpin.CompactUsageTemplate` provides a more compact representation for more complex command-line structures, -`kingpin.SeparateOptionalFlagsUsageTemplate` looks like the default template, but splits required -and optional command flags into separate lists, and `kingpin.ManPageTemplate` is used to generate man pages. - -See the above templates for examples of usage, and the the function [UsageForContextWithTemplate()](https://github.com/alecthomas/kingpin/blob/master/usage.go#L198) method for details on the context. - -#### Default help template - -``` -$ go run ./examples/curl/curl.go --help -usage: curl [] [ ...] - -An example implementation of curl. - -Flags: - --help Show help. - -t, --timeout=5s Set connection timeout. - -H, --headers=HEADER=VALUE - Add HTTP headers to the request. - -Commands: - help [...] - Show help. - - get url - Retrieve a URL. - - get file - Retrieve a file. - - post [] - POST a resource. -``` - -#### Compact help template - -``` -$ go run ./examples/curl/curl.go --help -usage: curl [] [ ...] - -An example implementation of curl. - -Flags: - --help Show help. - -t, --timeout=5s Set connection timeout. - -H, --headers=HEADER=VALUE - Add HTTP headers to the request. - -Commands: - help [...] - get [] - url - file - post [] -``` diff --git a/src/cfdnsupdater/Godeps/_workspace/src/gopkg.in/alecthomas/kingpin.v2/actions.go b/src/cfdnsupdater/Godeps/_workspace/src/gopkg.in/alecthomas/kingpin.v2/actions.go deleted file mode 100644 index 72d6cbd..0000000 --- a/src/cfdnsupdater/Godeps/_workspace/src/gopkg.in/alecthomas/kingpin.v2/actions.go +++ /dev/null @@ -1,42 +0,0 @@ -package kingpin - -// Action callback executed at various stages after all values are populated. -// The application, commands, arguments and flags all have corresponding -// actions. -type Action func(*ParseContext) error - -type actionMixin struct { - actions []Action - preActions []Action -} - -type actionApplier interface { - applyActions(*ParseContext) error - applyPreActions(*ParseContext) error -} - -func (a *actionMixin) addAction(action Action) { - a.actions = append(a.actions, action) -} - -func (a *actionMixin) addPreAction(action Action) { - a.preActions = append(a.preActions, action) -} - -func (a *actionMixin) applyActions(context *ParseContext) error { - for _, action := range a.actions { - if err := action(context);
