Despite its name, this package -is maintained only as part of the Azure Go SDK and is not related to other -"ADAL" libraries in [github.com/AzureAD](https://github.com/AzureAD). - -## Overview - -Package go-autorest implements an HTTP request pipeline suitable for use across -multiple goroutines and provides the shared routines used by packages generated -by [Autorest](https://github.com/Azure/autorest.go). - -The package breaks sending and responding to HTTP requests into three phases: Preparing, Sending, -and Responding. A typical pattern is: - -```go - req, err := Prepare(&http.Request{}, - token.WithAuthorization()) - - resp, err := Send(req, - WithLogging(logger), - DoErrorIfStatusCode(http.StatusInternalServerError), - DoCloseIfError(), - DoRetryForAttempts(5, time.Second)) - - err = Respond(resp, - ByDiscardingBody(), - ByClosing()) -``` - -Each phase relies on decorators to modify and / or manage processing. Decorators may first modify -and then pass the data along, pass the data first and then modify the result, or wrap themselves -around passing the data (such as a logger might do). Decorators run in the order provided. For -example, the following: - -```go - req, err := Prepare(&http.Request{}, - WithBaseURL("https://microsoft.com/"), - WithPath("a"), - WithPath("b"), - WithPath("c")) -``` - -will set the URL to: - -``` - https://microsoft.com/a/b/c -``` - -Preparers and Responders may be shared and re-used (assuming the underlying decorators support -sharing and re-use). Performant use is obtained by creating one or more Preparers and Responders -shared among multiple go-routines, and a single Sender shared among multiple sending go-routines, -all bound together by means of input / output channels. - -Decorators hold their passed state within a closure (such as the path components in the example -above). Be careful to share Preparers and Responders only in a context where such held state -applies. For example, it may not make sense to share a Preparer that applies a query string from a -fixed set of values. Similarly, sharing a Responder that reads the response body into a passed -struct (e.g., `ByUnmarshallingJson`) is likely incorrect. - -Errors raised by autorest objects and methods will conform to the `autorest.Error` interface. - -See the included examples for more detail. For details on the suggested use of this package by -generated clients, see the Client described below. - -## Helpers - -### Handling Swagger Dates - -The Swagger specification (https://swagger.io) that drives AutoRest -(https://github.com/Azure/autorest/) precisely defines two date forms: date and date-time. The -github.com/Azure/go-autorest/autorest/date package provides time.Time derivations to ensure correct -parsing and formatting. - -### Handling Empty Values - -In JSON, missing values have different semantics than empty values. This is especially true for -services using the HTTP PATCH verb. The JSON submitted with a PATCH request generally contains -only those values to modify. Missing values are to be left unchanged. Developers, then, require a -means to both specify an empty value and to leave the value out of the submitted JSON. - -The Go JSON package (`encoding/json`) supports the `omitempty` tag. When specified, it omits -empty values from the rendered JSON. Since Go defines default values for all base types (such as "" -for string and 0 for int) and provides no means to mark a value as actually empty, the JSON package -treats default values as meaning empty, omitting them from the rendered JSON. This means that, using -the Go base types encoded through the default JSON package, it is not possible to create JSON to -clear a value at the server. - -The workaround within the Go community is to use pointers to base types in lieu of base types within -structures that map to JSON. For example, instead of a value of type `string`, the workaround uses -`*string`. While this enables distinguishing empty values from those to be unchanged, creating -pointers to a base type (notably constant, in-line values) requires additional variables.

So this operation cannot **not** be done. For this reason, `FlagRemoveEmptyQuerySeparator` (as well as the other three) has been included in the `FlagsSafe` convenience set, instead of `FlagsUnsafe`, where Wikipedia puts it. - -* The `FlagDecodeUnnecessaryEscapes` decodes the following escapes (*from -> to*): - - %24 -> $ - - %26 -> & - - %2B-%3B -> +,-./0123456789:; - - %3D -> = - - %40-%5A -> @ABCDEFGHIJKLMNOPQRSTUVWXYZ - - %5F -> _ - - %61-%7A -> abcdefghijklmnopqrstuvwxyz - - %7E -> ~ - - -* When the `NormalizeURL` function is used (passing an URL object), this source URL object is modified (that is, after the call, the URL object will be modified to reflect the normalization). - -* The *replace IP with domain name* normalization (`http://208.77.188.166/ → http://www.example.com/`) is obviously not possible for a library without making some network requests. This is not implemented in purell. - -* The *remove unused query string parameters* and *remove default query parameters* are also not implemented, since this is a very case-specific normalization, and it is quite trivial to do with an URL object. - -### Safe vs Usually Safe vs Unsafe - -Purell allows you to control the level of risk you take while normalizing an URL. You can aggressively normalize, play it totally safe, or anything in between. - -Consider the following URL: - -`HTTPS://www.RooT.com/toto/t%45%1f///a/./b/../c/?z=3&w=2&a=4&w=1#invalid` - -Normalizing with the `FlagsSafe` gives: - -`https://www.root.com/toto/tE%1F///a/./b/../c/?z=3&w=2&a=4&w=1#invalid` - -With the `FlagsUsuallySafeGreedy`: - -`https://www.root.com/toto/tE%1F///a/c?z=3&w=2&a=4&w=1#invalid` - -And with `FlagsUnsafeGreedy`: - -`http://root.com/toto/tE%1F/a/c?a=4&w=1&w=2&z=3` - -## TODOs - -* Add a class/default instance to allow specifying custom directory index names?

It's commonly used for `Bearer` tokens in Oauth 2. A token is made of three parts, separated by `.`'s. The first two parts are JSON objects, that have been [base64url](https://datatracker.ietf.org/doc/html/rfc4648) encoded. The last part is the signature, encoded the same way. - -The first part is called the header. It contains the necessary information for verifying the last part, the signature. For example, which encryption method was used for signing and what key was used. - -The part in the middle is the interesting bit. It's called the Claims and contains the actual stuff you care about. Refer to [RFC 7519](https://datatracker.ietf.org/doc/html/rfc7519) for information about reserved keys and the proper way to add your own. - -## What's in the box? - -This library supports the parsing and verification as well as the generation and signing of JWTs. Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own. - -## Examples - -See [the project documentation](https://pkg.go.dev/github.com/golang-jwt/jwt) for examples of usage: - -* [Simple example of parsing and validating a token](https://pkg.go.dev/github.com/golang-jwt/jwt#example-Parse-Hmac) -* [Simple example of building and signing a token](https://pkg.go.dev/github.com/golang-jwt/jwt#example-New-Hmac) -* [Directory of Examples](https://pkg.go.dev/github.com/golang-jwt/jwt#pkg-examples) - -## Extensions - -This library publishes all the necessary components for adding your own signing methods. Simply implement the `SigningMethod` interface and register a factory method using `RegisterSigningMethod`. - -Here's an example of an extension that integrates with multiple Google Cloud Platform signing tools (AppEngine, IAM API, Cloud KMS): https://github.com/someone1/gcp-jwt-go - -## Compliance - -This library was last reviewed to comply with [RFC 7519](https://datatracker.ietf.org/doc/html/rfc7519) dated May 2015 with a few notable differences: - -* In order to protect against accidental use of [Unsecured JWTs](https://datatracker.ietf.org/doc/html/rfc7519#section-6), tokens using `alg=none` will only be accepted if the constant `jwt.UnsafeAllowNoneSignatureType` is provided as the key. - -## Project Status & Versioning - -This library is considered production ready. Feedback and feature requests are appreciated. The API should be considered stable. There should be very few backwards-incompatible changes outside of major version updates (and only with good reason). - -This project uses [Semantic Versioning 2.0.0](http://semver.org). Accepted pull requests will land on `main`. Periodically, versions will be tagged from `main`. You can find all the releases on [the project releases page](https://github.com/golang-jwt/jwt/releases). - -**BREAKING CHANGES:*** -A full list of breaking changes is available in `VERSION_HISTORY.md`. See `MIGRATION_GUIDE.md` for more information on updating your code. - -## Usage Tips - -### Signing vs Encryption - -A token is simply a JSON object that is signed by its author. this tells you exactly two things about the data: - -* The author of the token was in the possession of the signing secret -* The data has not been modified since it was signed - -It's important to know that JWT does not provide encryption, which means anyone who has access to the token can read its contents. If you need to protect (encrypt) the data, there is a companion spec, `JWE`, that provides this functionality. JWE is currently outside the scope of this library. - -### Choosing a Signing Method - -There are several signing methods available, and you should probably take the time to learn about the various options before choosing one. The principal design decision is most likely going to be symmetric vs asymmetric. - -Symmetric signing methods, such as HSA, use only a single secret. This is probably the simplest signing method to use since any `[]byte` can be used as a valid secret. They are also slightly computationally faster to use, though this rarely is enough to matter. Symmetric signing methods work the best when both producers and consumers of tokens are trusted, or even the same system. Since the same secret is used to both sign and validate tokens, you can't easily distribute the key for validation. - -Asymmetric signing methods, such as RSA, use different keys for signing and verifying tokens. This makes it possible to produce tokens with a private key, and allow any consumer to access the public key for verification. - -### Signing Methods and Key Types - -Each signing method expects a different object type for its signing keys. See the package documentation for details. Here are the most common ones: - -* The [HMAC signing method](https://pkg.go.dev/github.com/golang-jwt/jwt#SigningMethodHMAC) (`HS256`,`HS384`,`HS512`) expect `[]byte` values for signing and validation -* The [RSA signing method](https://pkg.go.dev/github.com/golang-jwt/jwt#SigningMethodRSA) (`RS256`,`RS384`,`RS512`) expect `*rsa.PrivateKey` for signing and `*rsa.PublicKey` for validation -* The [ECDSA signing method](https://pkg.go.dev/github.com/golang-jwt/jwt#SigningMethodECDSA) (`ES256`,`ES384`,`ES512`) expect `*ecdsa.PrivateKey` for signing and `*ecdsa.PublicKey` for validation -* The [EdDSA signing method](https://pkg.go.dev/github.com/golang-jwt/jwt#SigningMethodEd25519) (`Ed25519`) expect `ed25519.PrivateKey` for signing and `ed25519.PublicKey` for validation - -### JWT and OAuth - -It's worth mentioning that OAuth and JWT are not the same thing. A JWT token is simply a signed JSON object. It can be used anywhere such a thing is useful. There is some confusion, though, as JWT is the most common type of bearer token used in OAuth2 authentication. - -Without going too far down the rabbit hole, here's a description of the interaction of these technologies: - -* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to. For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth. -* OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token. -* Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL. - -### Troubleshooting - -This library uses descriptive error messages whenever possible. If you are not getting the expected result, have a look at the errors. The most common place people get stuck is providing the correct type of key to the parser. See the above section on signing methods and key types. - -## More - -Documentation can be found [on pkg.go.dev](https://pkg.go.dev/github.com/golang-jwt/jwt). - -The command line utility included in this project (cmd/jwt) provides a straightforward example of token creation and parsing as well as a useful tool for debugging your own integration. You'll also find several implementation examples in the documentation. diff --git a/vendor/github.com/golang-jwt/jwt/v4/VERSION_HISTORY.md b/vendor/github.com/golang-jwt/jwt/v4/VERSION_HISTORY.md deleted file mode 100644 index afbfc4e4..00000000 --- a/vendor/github.com/golang-jwt/jwt/v4/VERSION_HISTORY.md +++ /dev/null @@ -1,135 +0,0 @@ -## `jwt-go` Version History - -#### 4.0.0 - -* Introduces support for Go modules. The `v4` version will be backwards compatible with `v3.x.y`. - -#### 3.2.2 - -* Starting from this release, we are adopting the policy to support the most 2 recent versions of Go currently available. By the time of this release, this is Go 1.15 and 1.16 ([#28](https://github.com/golang-jwt/jwt/pull/28)). -* Fixed a potential issue that could occur when the verification of `exp`, `iat` or `nbf` was not required and contained invalid contents, i.e. non-numeric/date. Thanks for @thaJeztah for making us aware of that and @giorgos-f3 for originally reporting it to the formtech fork ([#40](https://github.com/golang-jwt/jwt/pull/40)). -* Added support for EdDSA / ED25519 ([#36](https://github.com/golang-jwt/jwt/pull/36)). -* Optimized allocations ([#33](https://github.com/golang-jwt/jwt/pull/33)). - -#### 3.2.1 - -* **Import Path Change**: See MIGRATION_GUIDE.md for tips on updating your code - * Changed the import path from `github.com/dgrijalva/jwt-go` to `github.com/golang-jwt/jwt` -* Fixed type confusing issue between `string` and `[]string` in `VerifyAudience` ([#12](https://github.com/golang-jwt/jwt/pull/12)). This fixes CVE-2020-26160 - -#### 3.2.0 - -* Added method `ParseUnverified` to allow users to split up the tasks of parsing and validation -* HMAC signing method returns `ErrInvalidKeyType` instead of `ErrInvalidKey` where appropriate -* Added options to `request.ParseFromRequest`, which allows for an arbitrary list of modifiers to parsing behavior. Initial set include `WithClaims` and `WithParser`. Existing usage of this function will continue to work as before. -* Deprecated `ParseFromRequestWithClaims` to simplify API in the future. - -#### 3.1.0 - -* Improvements to `jwt` command line tool -* Added `SkipClaimsValidation` option to `Parser` -* Documentation updates - -#### 3.0.0 - -* **Compatibility Breaking Changes**: See MIGRATION_GUIDE.md for tips on updating your code - * Dropped support for `[]byte` keys when using RSA signing methods. This convenience feature could contribute to security vulnerabilities involving mismatched key types with signing methods. - * `ParseFromRequest` has been moved to `request` subpackage and usage has changed - * The `Claims` property on `Token` is now type `Claims` instead of `map[string]interface{}`. The default value is type `MapClaims`, which is an alias to `map[string]interface{}`. This makes it possible to use a custom type when decoding claims. -* Other Additions and Changes - * Added `Claims` interface type to allow users to decode the claims into a custom type - * Added `ParseWithClaims`, which takes a third argument of type `Claims`. Use this function instead of `Parse` if you have a custom type you'd like to decode into. - * Dramatically improved the functionality and flexibility of `ParseFromRequest`, which is now in the `request` subpackage - * Added `ParseFromRequestWithClaims` which is the `FromRequest` equivalent of `ParseWithClaims` - * Added new interface type `Extractor`, which is used for extracting JWT strings from http requests. Used with `ParseFromRequest` and `ParseFromRequestWithClaims`. - * Added several new, more specific, validation errors to error type bitmask - * Moved examples from README to executable example files - * Signing method registry is now thread safe - * Added new property to `ValidationError`, which contains the raw error returned by calls made by parse/verify (such as those returned by keyfunc or json parser) - -#### 2.7.0 - -This will likely be the last backwards compatible release before 3.0.0, excluding essential bug fixes. - -* Added new option `-show` to the `jwt` command that will just output the decoded token without verifying -* Error text for expired tokens includes how long it's been expired -* Fixed incorrect error returned from `ParseRSAPublicKeyFromPEM` -* Documentation updates - -#### 2.6.0 - -* Exposed inner error within ValidationError -* Fixed validation errors when using UseJSONNumber flag -* Added several unit tests - -#### 2.5.0 - -* Added support for signing method none. You shouldn't use this. The API tries to make this clear. -* Updated/fixed some documentation -* Added more helpful error message when trying to parse tokens that begin with `BEARER ` - -#### 2.4.0 - -* Added new type, Parser, to allow for configuration of various parsing parameters - * You can now specify a list of valid signing methods. Anything outside this set will be rejected. - * You can now opt to use the `json.Number` type instead of `float64` when parsing token JSON -* Added support for [Travis CI](https://travis-ci.org/dgrijalva/jwt-go) -* Fixed some bugs with ECDSA parsing - -#### 2.3.0 - -* Added support for ECDSA signing methods -* Added support for RSA PSS signing methods (requires go v1.4) - -#### 2.2.0 - -* Gracefully handle a `nil` `Keyfunc` being passed to `Parse`. Result will now be the parsed token and an error, instead of a panic. - -#### 2.1.0 - -Backwards compatible API change that was missed in 2.0.0. - -* The `SignedString` method on `Token` now takes `interface{}` instead of `[]byte` - -#### 2.0.0 - -There were two major reasons for breaking backwards compatibility with this update. The first was a refactor required to expand the width of the RSA and HMAC-SHA signing implementations. There will likely be no required code changes to support this change. - -The second update, while unfortunately requiring a small change in integration, is required to open up this library to other signing methods. Not all keys used for all signing methods have a single standard on-disk representation. Requiring `[]byte` as the type for all keys proved too limiting. Additionally, this implementation allows for pre-parsed tokens to be reused, which might matter in an application that parses a high volume of tokens with a small set of keys. Backwards compatibilty has been maintained for passing `[]byte` to the RSA signing methods, but they will also accept `*rsa.PublicKey` and `*rsa.PrivateKey`. - -It is likely the only integration change required here will be to change `func(t *jwt.Token) ([]byte, error)` to `func(t *jwt.Token) (interface{}, error)` when calling `Parse`. - -* **Compatibility Breaking Changes** - * `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct` - * `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct` - * `KeyFunc` now returns `interface{}` instead of `[]byte` - * `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key - * `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key -* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`. Specific sizes are now just instances of this type. - * Added public package global `SigningMethodHS256` - * Added public package global `SigningMethodHS384` - * Added public package global `SigningMethodHS512` -* Renamed type `SigningMethodRS256` to `SigningMethodRSA`. Specific sizes are now just instances of this type. - * Added public package global `SigningMethodRS256` - * Added public package global `SigningMethodRS384` - * Added public package global `SigningMethodRS512` -* Moved sample private key for HMAC tests from an inline value to a file on disk. Value is unchanged. -* Refactored the RSA implementation to be easier to read -* Exposed helper methods `ParseRSAPrivateKeyFromPEM` and `ParseRSAPublicKeyFromPEM` - -#### 1.0.2 - -* Fixed bug in parsing public keys from certificates -* Added more tests around the parsing of keys for RS256 -* Code refactoring in RS256 implementation. No functional changes - -#### 1.0.1 - -* Fixed panic if RS256 signing method was passed an invalid key - -#### 1.0.0 - -* First versioned release -* API stabilized -* Supports creating, signing, parsing, and validating JWT tokens -* Supports RS256 and HS256 signing methods diff --git a/vendor/github.com/golang-jwt/jwt/v4/claims.go b/vendor/github.com/golang-jwt/jwt/v4/claims.go deleted file mode 100644 index 41cc8265..00000000 --- a/vendor/github.com/golang-jwt/jwt/v4/claims.go +++ /dev/null @@ -1,273 +0,0 @@ -package jwt - -import ( - "crypto/subtle" - "fmt" - "time" -) - -// Claims must just have a Valid method that determines -// if the token is invalid for any supported reason -type Claims interface { - Valid() error -} - -// RegisteredClaims are a structured version of the JWT Claims Set, -// restricted to Registered Claim Names, as referenced at -// https://datatracker.ietf.org/doc/html/rfc7519#section-4.1 -// -// This type can be used on its own, but then additional private and -// public claims embedded in the JWT will not be parsed.

The interpretation of +// binary messages is left to the application. +// +// This package uses the TextMessage and BinaryMessage integer constants to +// identify the two data message types. The ReadMessage and NextReader methods +// return the type of the received message. The messageType argument to the +// WriteMessage and NextWriter methods specifies the type of a sent message. +// +// It is the application's responsibility to ensure that text messages are +// valid UTF-8 encoded text. +// +// Control Messages +// +// The WebSocket protocol defines three types of control messages: close, ping +// and pong. Call the connection WriteControl, WriteMessage or NextWriter +// methods to send a control message to the peer. +// +// Connections handle received close messages by calling the handler function +// set with the SetCloseHandler method and by returning a *CloseError from the +// NextReader, ReadMessage or the message Read method. The default close +// handler sends a close message to the peer. +// +// Connections handle received ping messages by calling the handler function +// set with the SetPingHandler method. The default ping handler sends a pong +// message to the peer. +// +// Connections handle received pong messages by calling the handler function +// set with the SetPongHandler method. The default pong handler does nothing. +// If an application sends ping messages, then the application should set a +// pong handler to receive the corresponding pong. +// +// The control message handler functions are called from the NextReader, +// ReadMessage and message reader Read methods. The default close and ping +// handlers can block these methods for a short time when the handler writes to +// the connection. +// +// The application must read the connection to process close, ping and pong +// messages sent from the peer. If the application is not otherwise interested +// in messages from the peer, then the application should start a goroutine to +// read and discard messages from the peer. A simple example is: +// +// func readLoop(c *websocket.Conn) { +// for { +// if _, _, err := c.NextReader(); err != nil { +// c.Close() +// break +// } +// } +// } +// +// Concurrency +// +// Connections support one concurrent reader and one concurrent writer. +// +// Applications are responsible for ensuring that no more than one goroutine +// calls the write methods (NextWriter, SetWriteDeadline, WriteMessage, +// WriteJSON, EnableWriteCompression, SetCompressionLevel) concurrently and +// that no more than one goroutine calls the read methods (NextReader, +// SetReadDeadline, ReadMessage, ReadJSON, SetPongHandler, SetPingHandler) +// concurrently. +// +// The Close and WriteControl methods can be called concurrently with all other +// methods. +// +// Origin Considerations +// +// Web browsers allow Javascript applications to open a WebSocket connection to +// any host. It's up to the server to enforce an origin policy using the Origin +// request header sent by the browser. +// +// The Upgrader calls the function specified in the CheckOrigin field to check +// the origin. If the CheckOrigin function returns false, then the Upgrade +// method fails the WebSocket handshake with HTTP status 403. +// +// If the CheckOrigin field is nil, then the Upgrader uses a safe default: fail +// the handshake if the Origin request header is present and the Origin host is +// not equal to the Host request header. +// +// The deprecated package-level Upgrade function does not perform origin +// checking. The application is responsible for checking the Origin header +// before calling the Upgrade function. +// +// 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.

It -is paranoid about its input (so you can safely feed it user-supplied -data), it is fast, it supports common extensions (tables, smart -punctuation substitutions, etc.), and it is safe for all utf-8 -(unicode) input. - -HTML output is currently supported, along with Smartypants -extensions. - -It started as a translation from C of [Sundown][3]. - - -Installation ------------- - -Blackfriday is compatible with any modern Go release. With Go and git installed: - - go get -u gopkg.in/russross/blackfriday.v2 - -will download, compile, and install the package into your `$GOPATH` directory -hierarchy. - - -Versions --------- - -Currently maintained and recommended version of Blackfriday is `v2`. It's being -developed on its own branch: https://github.com/russross/blackfriday/tree/v2 and the -documentation is available at -https://godoc.org/gopkg.in/russross/blackfriday.v2. - -It is `go get`-able via [gopkg.in][6] at `gopkg.in/russross/blackfriday.v2`, -but we highly recommend using package management tool like [dep][7] or -[Glide][8] and make use of semantic versioning. With package management you -should import `github.com/russross/blackfriday` and specify that you're using -version 2.0.0. - -Version 2 offers a number of improvements over v1: - -* Cleaned up API -* A separate call to [`Parse`][4], which produces an abstract syntax tree for - the document -* Latest bug fixes -* Flexibility to easily add your own rendering extensions - -Potential drawbacks: - -* Our benchmarks show v2 to be slightly slower than v1. Currently in the - ballpark of around 15%. -* API breakage. If you can't afford modifying your code to adhere to the new API - and don't care too much about the new features, v2 is probably not for you. -* Several bug fixes are trailing behind and still need to be forward-ported to - v2. See issue [#348](https://github.com/russross/blackfriday/issues/348) for - tracking. - -If you are still interested in the legacy `v1`, you can import it from -`github.com/russross/blackfriday`. Documentation for the legacy v1 can be found -here: https://godoc.org/github.com/russross/blackfriday - -### Known issue with `dep` - -There is a known problem with using Blackfriday v1 _transitively_ and `dep`. -Currently `dep` prioritizes semver versions over anything else, and picks the -latest one, plus it does not apply a `[[constraint]]` specifier to transitively -pulled in packages. So if you're using something that uses Blackfriday v1, but -that something does not use `dep` yet, you will get Blackfriday v2 pulled in and -your first dependency will fail to build. - -There are couple of fixes for it, documented here: -https://github.com/golang/dep/blob/master/docs/FAQ.md#how-do-i-constrain-a-transitive-dependencys-version - -Meanwhile, `dep` team is working on a more general solution to the constraints -on transitive dependencies problem: https://github.com/golang/dep/issues/1124. - - -Usage ------ - -### v1 - -For basic usage, it is as simple as getting your input into a byte -slice and calling: - - output := blackfriday.MarkdownBasic(input) - -This renders it with no extensions enabled. To get a more useful -feature set, use this instead: - - output := blackfriday.MarkdownCommon(input) - -### v2 - -For the most sensible markdown processing, it is as simple as getting your input -into a byte slice and calling: - -```go -output := blackfriday.Run(input) -``` - -Your input will be parsed and the output rendered with a set of most popular -extensions enabled. If you want the most basic feature set, corresponding with -the bare Markdown specification, use: - -```go -output := blackfriday.Run(input, blackfriday.WithNoExtensions()) -``` - -### Sanitize untrusted content - -Blackfriday itself does nothing to protect against malicious content. If you are -dealing with user-supplied markdown, we recommend running Blackfriday's output -through HTML sanitizer such as [Bluemonday][5]. - -Here's an example of simple usage of Blackfriday together with Bluemonday: - -```go -import ( - "github.com/microcosm-cc/bluemonday" - "gopkg.in/russross/blackfriday.v2" -) - -// ... -unsafe := blackfriday.Run(input) -html := bluemonday.UGCPolicy().SanitizeBytes(unsafe) -``` - -### Custom options, v1 - -If you want to customize the set of options, first get a renderer -(currently only the HTML output engine), then use it to -call the more general `Markdown` function. For examples, see the -implementations of `MarkdownBasic` and `MarkdownCommon` in -`markdown.go`. - -### Custom options, v2 - -If you want to customize the set of options, use `blackfriday.WithExtensions`, -`blackfriday.WithRenderer` and `blackfriday.WithRefOverride`. - -### `blackfriday-tool` - -You can also check out `blackfriday-tool` for a more complete example -of how to use it. Download and install it using: - - go get github.com/russross/blackfriday-tool - -This is a simple command-line tool that allows you to process a -markdown file using a standalone program. You can also browse the -source directly on github if you are just looking for some example -code: - -* - -Note that if you have not already done so, installing -`blackfriday-tool` will be sufficient to download and install -blackfriday in addition to the tool itself. The tool binary will be -installed in `$GOPATH/bin`. This is a statically-linked binary that -can be copied to wherever you need it without worrying about -dependencies and library versions. - -### Sanitized anchor names - -Blackfriday includes an algorithm for creating sanitized anchor names -corresponding to a given input text. This algorithm is used to create -anchors for headings when `EXTENSION_AUTO_HEADER_IDS` is enabled. The -algorithm has a specification, so that other packages can create -compatible anchor names and links to those anchors. - -The specification is located at https://godoc.org/github.com/russross/blackfriday#hdr-Sanitized_Anchor_Names. - -[`SanitizedAnchorName`](https://godoc.org/github.com/russross/blackfriday#SanitizedAnchorName) exposes this functionality, and can be used to -create compatible links to the anchor names generated by blackfriday. -This algorithm is also implemented in a small standalone package at -[`github.com/shurcooL/sanitized_anchor_name`](https://godoc.org/github.com/shurcooL/sanitized_anchor_name). It can be useful for clients -that want a small package and don't need full functionality of blackfriday. - - -Features --------- - -All features of Sundown are supported, including: - -* **Compatibility**. The Markdown v1.0.3 test suite passes with - the `--tidy` option. Without `--tidy`, the differences are - mostly in whitespace and entity escaping, where blackfriday is - more consistent and cleaner. - -* **Common extensions**, including table support, fenced code - blocks, autolinks, strikethroughs, non-strict emphasis, etc. - -* **Safety**. Blackfriday is paranoid when parsing, making it safe - to feed untrusted user input without fear of bad things - happening. The test suite stress tests this and there are no - known inputs that make it crash. If you find one, please let me - know and send me the input that does it. - - NOTE: "safety" in this context means *runtime safety only*. In order to - protect yourself against JavaScript injection in untrusted content, see - [this example](https://github.com/russross/blackfriday#sanitize-untrusted-content). - -* **Fast processing**. It is fast enough to render on-demand in - most web applications without having to cache the output. - -* **Thread safety**. You can run multiple parsers in different - goroutines without ill effect. There is no dependence on global - shared state. - -* **Minimal dependencies**. Blackfriday only depends on standard - library packages in Go. The source code is pretty - self-contained, so it is easy to add to any project, including - Google App Engine projects. - -* **Standards compliant**. Output successfully validates using the - W3C validation tool for HTML 4.01 and XHTML 1.0 Transitional. - - -Extensions ----------- - -In addition to the standard markdown syntax, this package -implements the following extensions: - -* **Intra-word emphasis supression**. The `_` character is - commonly used inside words when discussing code, so having - markdown interpret it as an emphasis command is usually the - wrong thing. Blackfriday lets you treat all emphasis markers as - normal characters when they occur inside a word. - -* **Tables**. Tables can be created by drawing them in the input - using a simple syntax: - - ``` - Name | Age - --------|------ - Bob | 27 - Alice | 23 - ``` - -* **Fenced code blocks**. In addition to the normal 4-space - indentation to mark code blocks, you can explicitly mark them - and supply a language (to make syntax highlighting simple). Just - mark it like this: - - ``` go - func getTrue() bool { - return true - } - ``` - - You can use 3 or more backticks to mark the beginning of the - block, and the same number to mark the end of the block. - - To preserve classes of fenced code blocks while using the bluemonday - HTML sanitizer, use the following policy: - - ``` go - p := bluemonday.UGCPolicy() - p.AllowAttrs("class").Matching(regexp.MustCompile("^language-[a-zA-Z0-9]+$")).OnElements("code") - html := p.SanitizeBytes(unsafe) - ``` - -* **Definition lists**. A simple definition list is made of a single-line - term followed by a colon and the definition for that term. - - Cat - : Fluffy animal everyone likes - - Internet - : Vector of transmission for pictures of cats - - Terms must be separated from the previous definition by a blank line. - -* **Footnotes**. A marker in the text that will become a superscript number; - a footnote definition that will be placed in a list of footnotes at the - end of the document. A footnote looks like this: - - This is a footnote.[^1] - - [^1]: the footnote text. - -* **Autolinking**. Blackfriday can find URLs that have not been - explicitly marked as links and turn them into links. - -* **Strikethrough**. Use two tildes (`~~`) to mark text that - should be crossed out. - -* **Hard line breaks**. With this extension enabled (it is off by - default in the `MarkdownBasic` and `MarkdownCommon` convenience - functions), newlines in the input translate into line breaks in - the output. - -* **Smart quotes**. Smartypants-style punctuation substitution is - supported, turning normal double- and single-quote marks into - curly quotes, etc. - -* **LaTeX-style dash parsing** is an additional option, where `--` - is translated into `–`, and `---` is translated into - `—`. This differs from most smartypants processors, which - turn a single hyphen into an ndash and a double hyphen into an - mdash. - -* **Smart fractions**, where anything that looks like a fraction - is translated into suitable HTML (instead of just a few special - cases like most smartypant processors). For example, `4/5` - becomes `4⁄5`, which renders as - 4⁄5. - - -Other renderers ---------------- - -Blackfriday is structured to allow alternative rendering engines. Here -are a few of note: - -* [github_flavored_markdown](https://godoc.org/github.com/shurcooL/github_flavored_markdown): - provides a GitHub Flavored Markdown renderer with fenced code block - highlighting, clickable heading anchor links. - - It's not customizable, and its goal is to produce HTML output - equivalent to the [GitHub Markdown API endpoint](https://developer.github.com/v3/markdown/#render-a-markdown-document-in-raw-mode), - except the rendering is performed locally. - -* [markdownfmt](https://github.com/shurcooL/markdownfmt): like gofmt, - but for markdown. - -* [LaTeX output](https://bitbucket.org/ambrevar/blackfriday-latex): - renders output as LaTeX. - -* [bfchroma](https://github.com/Depado/bfchroma/): provides convenience - integration with the [Chroma](https://github.com/alecthomas/chroma) code - highlighting library. bfchroma is only compatible with v2 of Blackfriday and - provides a drop-in renderer ready to use with Blackfriday, as well as - options and means for further customization. - - -TODO ----- - -* More unit testing -* Improve Unicode support. It does not understand all Unicode - rules (about what constitutes a letter, a punctuation symbol, - etc.), so it may fail to detect word boundaries correctly in - some instances. It is safe on all UTF-8 input. - - -License -------- - -[Blackfriday is distributed under the Simplified BSD License](LICENSE.txt) - - - [1]: https://daringfireball.net/projects/markdown/ "Markdown" - [2]: https://golang.org/ "Go Language" - [3]: https://github.com/vmg/sundown "Sundown" - [4]: https://godoc.org/gopkg.in/russross/blackfriday.v2#Parse "Parse func" - [5]: https://github.com/microcosm-cc/bluemonday "Bluemonday" - [6]: https://labix.org/gopkg.in "gopkg.in" - [7]: https://github.com/golang/dep/ "dep" - [8]: https://github.com/Masterminds/glide "Glide" - - [BuildSVG]: https://travis-ci.org/russross/blackfriday.svg?branch=master - [BuildURL]: https://travis-ci.org/russross/blackfriday - [GodocV2SVG]: https://godoc.org/gopkg.in/russross/blackfriday.v2?status.svg - [GodocV2URL]: https://godoc.org/gopkg.in/russross/blackfriday.v2 diff --git a/vendor/github.com/russross/blackfriday/block.go b/vendor/github.com/russross/blackfriday/block.go deleted file mode 100644 index 45c21a6c..00000000 --- a/vendor/github.com/russross/blackfriday/block.go +++ /dev/null @@ -1,1474 +0,0 @@ -// -// Blackfriday Markdown Processor -// Available at http://github.com/russross/blackfriday -// -// Copyright © 2011 Russ Ross . -// Distributed under the Simplified BSD License. -// See README.md for details. -// - -// -// Functions to parse block-level elements. -// - -package blackfriday - -import ( - "bytes" - "strings" - "unicode" -) - -// Parse block-level data. -// Note: this function and many that it calls assume that -// the input buffer ends with a newline. -func (p *parser) block(out *bytes.Buffer, data []byte) { - if len(data) == 0 || data[len(data)-1] != '\n' { - panic("block input is missing terminating newline") - } - - // this is called recursively: enforce a maximum depth - if p.nesting >= p.maxNesting { - return - } - p.nesting++ - - // parse out one block-level construct at a time - for len(data) > 0 { - // prefixed header: - // - // # Header 1 - // ## Header 2 - // ... - // ###### Header 6 - if p.isPrefixHeader(data) { - data = data[p.prefixHeader(out, data):] - continue - } - - // block of preformatted HTML: - // - //
