Client HTML Rendering

Package blackfriday is a markdown processor. It translates plain text with simple formatting rules into an AST, which can then be further processed to HTML (provided by Blackfriday itself) or other formats (provided by the community). The simplest way to invoke Blackfriday is to call the Run function. It will take a text input and produce a text output in HTML (or other format). A slightly more sophisticated way to use Blackfriday is to create a Markdown processor and to call Parse, which returns a syntax tree for the input document. You can leverage Blackfriday's parsing for content extraction from markdown documents. You can assign a custom renderer and set various options to the Markdown processor. If you're interested in calling Blackfriday from command line, see https://github.com/russross/blackfriday-tool. 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 AutoHeadingIDs extension is enabled. The algorithm is specified below, so that other packages can create compatible anchor names and links to those anchors. The algorithm iterates over the input text, interpreted as UTF-8, one Unicode code point (rune) at a time. All runes that are letters (category L) or numbers (category N) are considered valid characters. They are mapped to lower case, and included in the output. All other runes are considered invalid characters. Invalid characters that precede the first valid character, as well as invalid character that follow the last valid character are dropped completely. All other sequences of invalid characters between two valid characters are replaced with a single dash character '-'. 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. It can be useful for clients that want a small package and don't need full functionality of blackfriday.

Package vugu provides core functionality including vugu->go codegen and in-browser DOM syncing running in WebAssembly. See http://www.vugu.org/ Since Vugu projects can have both client-side (running in WebAssembly) as well as server-side functionality many of the items in this package are available in both environments. Some however are either only available or only generally useful in one environment. Common functionality includes the ComponentType interface, and ComponentInst struct corresponding to an instantiated componnet. VGNode and related structs are used to represent a virtual Document Object Model. It is based on golang.org/x/net/html but with additional fields needed for Vugu. Data hashing is performed by ComputeHash() and can be customized by implementing the DataHasher interface. Client-side code uses JSEnv to maintain a render loop and regenerate virtual DOM and efficiently synchronize it with the browser as needed. DOMEvent is a wrapper around events from the browser and EventEnv is used to synchronize data access when writing event handler code that spawns goroutines. Where appropriate, server-side stubs are available so components can be compiled for both client (WebAssembly) and server (server-side rendering and testing). Server-side code can use ParserGo and ParserGoPkg to parse .vugu files and code generate a corresponding .go file. StaticHTMLEnv can be used to generate static HTML, similar to the output of JSEnv but can be run on the server. Supported features are approximately the same minus event handling, unapplicable to static output.

Extensible Go library for creating fast, SSR-first frontend avoiding vanilla templating downsides. Creating asynchronous and dynamic layout parts is a complex problem for larger projects using `html/template`. This library tries to simplify overall setup and process. Let's go straight into a simple example. Then, we will dig into details, step by step, how it works. Kyoto provides a set of simple net/http handlers, handler builders and function wrappers to provide serving, pages rendering, component actions, etc. Anyway, this is not an ultimative solution for any case. If you ever need to wrap/extend existing functionality, library encourages this. See functions inside of nethttp.go file for details and advanced usage. Example: Kyoto provides a way to define components. It's a very common approach for modern libraries to manage frontend parts. In kyoto each component is a context receiver, which returns it's state. Each component becomes a part of the page or top-level component, which executes component asynchronously and gets a state future object. In that way your components are executing in a non-blocking way. Pages are just top-level components, where you can configure rendering and page related stuff. Example: As an option, you can wrap component with another function to accept additional paramenters from top-level page/component. Example: Kyoto provides a context, which holds common objects like http.ResponseWriter, *http.Request, etc. See kyoto.Context for details. Example: Kyoto provides a set of parameters and functions to provide a comfortable template building process. You can configure template building parameters with kyoto.TemplateConf configuration. See template.go for available functions and kyoto.TemplateConfiguration for configuration details. Example: Kyoto provides a way to simplify building dynamic UIs. For this purpose it has a feature named actions. Logic is pretty simple. Client calls an action (sends a request to the server). Action is executing on server side and server is sending updated component markup to the client which will be morphed into DOM. That's it. To use actions, you need to go through a few steps. You'll need to include a client into page (JS functions for communication) and register an actions handler for a needed component. Let's start from including a client. Then, let's register an actions handler for a needed component. That's all! Now we ready to use actions to provide a dynamic UI. Example: In this example you can see provided modifications to the quick start example. First, we've added a state and name into our components' markup. In this way we are saving our components' state between actions and find a component root. Unfortunately, we have to manually provide a component name for now, we haven't found a way to provide it dynamically. Second, we've added a reload button with onclick function call. We're using a function Action provided by a client. Action triggering will be described in details later. Third, we've added an action handler inside of our component. This handler will be executed when a client calls an action with a corresponding name. It's highly recommended to keep components' state as small as possible. It will be transmitted on each action call. Kyoto have multiple ways to trigger actions. Now we will check them one by one. This is the simplest way to trigger an action. It's just a function call with a referer (usually 'this', f.e. button) as a first argument (used to determine root), action name as a second argument and arguments as a rest. Arguments must to be JSON serializable. It's possible to trigger an action of another component. If you want to call an action of parent component, use $ prefix in action name. If you want to call an action of component by id, use <id:action> as an action name. This is a specific action which is triggered when a form is submitted. Usually called in onsubmit="..." attribute of a form. You'll need to implement 'Submit' action to handle this trigger. This is a special HTML attribute which will trigger an action on page load. This may be useful for components' lazy loading. With this special HTML attributes you can trigger an action with interval. Useful for components that must to be updated over time (f.e. charts, stats, etc). You can use this trigger with ssa:poll and ssa:poll.interval HTML attributes. This one attribute allows you to trigger an action when an element is visible on the screen. May be useful for lazy loading. Kyoto provides a way to control action flow. For now, it's possible to control display style on component call and push multiple UI updates to the client during a single action. Because kyoto makes a roundtrip to the server every time an action is triggered on the page, there are cases where the page may not react immediately to a user event (like a click). That's why the library provides a way to easily control display attributes on action call. You can use this HTML attribute to control display during action call. At the end of an action the layout will be restored. A small note. Don't forget to set a default display for loading elements like spinners and loaders. You can push multiple component UI updates during a single action call. Just call kyoto.ActionFlush(ctx, state) to initiate an update. Kyoto provides a way to control action rendering. Now there is at least 2 rendering options after an action call: morph (default) and replace. Morph will try to morph received markup to the current one with morphdom library. In case of an error, or explicit "replace" mode, markup will be replaced with x.outerHTML = '...'.

If you want to call an action of component by id, use <id:action> as an action name. This is a specific action which is triggered when a form is submitted. Usually called in onsubmit="..." attribute of a form. You'll need to implement 'Submit' action to handle this trigger. This is a special HTML attribute which will trigger an action on page load. This may be useful for components' lazy loading. With this special HTML attributes you can trigger an action with interval. Useful for components that must to be updated over time (f.e. charts, stats, etc). You can use this trigger with ssa:poll and ssa:poll.interval HTML attributes. This one attribute allows you to trigger an action when an element is visible on the screen. May be useful for lazy loading. Kyoto provides a way to control action flow. For now, it's possible to control display style on component call and push multiple UI updates to the client during a single action. Because kyoto makes a roundtrip to the server every time an action is triggered on the page, there are cases where the page may not react immediately to a user event (like a click). That's why the library provides a way to easily control display attributes on action call. You can use this HTML attribute to control display during action call. At the end of an action the layout will be restored. A small note. Don't forget to set a default display for loading elements like spinners and loaders. You can push multiple component UI updates during a single action call. Just call kyoto.ActionFlush(ctx, state) to initiate an update. Kyoto provides a way to control action rendering. Now there is at least 2 rendering options after an action call: morph (default) and replace. Morph will try to morph received markup to the current one with morphdom library. In case of an error, or explicit "replace" mode, markup will be replaced with x.outerHTML = '...'.

Package kyoto was made for creating fast, server side frontend avoiding vanilla templating downsides. It tries to address complexities in frontend domain like responsibility separation, components structure, asynchronous load and hassle-free dynamic layout updates. These issues are common for frontends written with Go. The library provides you with primitives for pages and components creation, state and rendering management, dynamic layout updates (with external packages integration), utility functions and asynchronous components out of the box. Still, it bundles with minimal dependencies and tries to utilize built-ins as much as possible. You would probably want to opt out from this library in few cases, like, if you're not ready for drastic API changes between major version, you want to develop SPA/PWA and/or complex client-side logic, or you're just feeling OK with your current setup. Please, don't compare kyoto with a popular JS libraries like React, Vue or Svelte. I know you will have such a desire, but most likely you will be wrong. Use cases and underlying principles are just too different. If you want to get an idea of what a typical static component would look like, here's some sample code. It's very ascetic and simplistic, as we don't want to overload you with implementation details. Markup is also not included here (it's just a well-known `html/template`). For details, please check project's website on https://kyoto.codes. Also, you may check the library index to explore available sub-packages and https://pkg.go.dev for Go'ish documentation style. We don't want you to deal with boilerplate code on your own, so you can proceed with our simple starter project. Feel free to use it as an example for your own setup. Components is a common approach for modern libraries to manage frontend parts. Kyoto's components are trying to be mostly independent (but configurable) part of the project. To create component, it would be enough to implement component.Component. It's a function, a context receiver which returns a component state. State is an implementation of component.State, which is easy to implement with nesting one of the state implementations (options will be described later). Each component becomes a part of the page or top-level component, which executes component function asynchronously and gets a state future object. In that way your components are executing in a non-blocking way. Pages are just top-level components, where you can configure rendering and page related stuff. Stateful components are pretty similar to stateless ones, but they are actually implementing marshal/unmarshal interface instead of mocking it. You have multiple state options to choose from: universal or server. Universal state is a state, that can be marshalled and unmarshalled both on server and client. It's a common state option without functionality limitations. On the other hand, the whole state must be sent and received, which applies some limitations on the state size. Server state can be marshalled and unmarshalled only on server. It's a good option for components, that are not supposed to be updated on client side (f.e. no inputs). Also, it's a good option for components with lots of state data. Sometimes you may want to pass some arguments to the component. It's easy to do with wrapping component with additional function. You have an access to the context inside the component. It includes request and response objects, as well as some other useful stuff like store. This library doesn't provide you with routing out of the box. You can use any router you want, built-in one is not a bad option for basic needs. Rendering might be tricky, but we're trying to make it as simple as possible. By default, we're using `html/template` as a rendering engine. It's a well-known built-in package, so you don't have to learn anything new. Out of the box we're parsing all templates in root directory with `*.html` glob. You can change this behavior with `TEMPLATE_GLOB` global variable. Don't rely on file names while working with template names, use `define` entry for each your component. To provide your components with ability to be rendered, you have to do some basic steps. First, you have to nest one of the rendering implementations into your component state (f.e. `rendering.Template`). You can customize rendering with providing values to the rendering implementation. If you need to modify these values for the entire project, we recommend looking at the global settings or creating a builder function for rendering object. By default, render handler will use a component name as a template name. So, you have to define a template with the same name as your component (not the filename, but "define" entry). That's enough to be rendered by `rendering.Handler`. For rendering a nested component, use built-in `template` function. Provide a resolved future object as a template argument in this way. Nested components are not obligated to have rendering implementation if you're using them in this way. As an alternative, you can nest rendering implementation (e.g. `rendering.Template`) into your nested component. In this way you can use `render` function to simplify your code. Please, don't use this approach heavily now, as it affects rendering performance. HTMX is a frontend library, that allows you to update your page layout dynamically. It perfectly fits into kyoto, which focuses on components and server side rendering. Thanks to the component structure, there is no need to define separate rendering logic specially for HTMX. Please, check https://htmx.org/docs/#installing for installation instructions. In addition to this, you must register HTMX handlers for your dynamic components. This is a basic example of HTMX usage. Please, check https://htmx.org/docs/ for more details. In this example we're defining a form component, that is updating itself on submit. And this is how you can define a component, that will handle this request. Sometimes it might be useful to have a component state, which will persist between requests and will be stored without any actual usage in the client side presentation. This function injects a hidden input field with a serialized state. Let's check how it works on the server side. As a result, we have a component with a persistent state between requests.

Extensible Go library for creating fast, SSR-first frontend avoiding vanilla templating downsides. Creating asynchronous and dynamic layout parts is a complex problem for larger projects using `html/template`. This library tries to simplify overall setup and process. Let's go straight into a simple example. Then, we will dig into details, step by step, how it works. Kyoto provides a set of simple net/http handlers, handler builders and function wrappers to provide serving, pages rendering, component actions, etc. Anyway, this is not an ultimative solution for any case. If you ever need to wrap/extend existing functionality, library encourages this. See functions inside of nethttp.go file for details and advanced usage. Example: Kyoto provides a way to define components. It's a very common approach for modern libraries to manage frontend parts. In kyoto each component is a context receiver, which returns it's state. Each component becomes a part of the page or top-level component, which executes component asynchronously and gets a state future object. In that way your components are executing in a non-blocking way. Pages are just top-level components, where you can configure rendering and page related stuff. Example: As an option, you can wrap component with another function to accept additional paramenters from top-level page/component. Example: Kyoto provides a context, which holds common objects like http.ResponseWriter, *http.Request, etc. See kyoto.Context for details. Example: Kyoto provides a set of parameters and functions to provide a comfortable template building process. You can configure template building parameters with kyoto.TemplateConf configuration. See template.go for available functions and kyoto.TemplateConfiguration for configuration details. Example: Kyoto provides a way to simplify building dynamic UIs. For this purpose it has a feature named actions. Logic is pretty simple. Client calls an action (sends a request to the server). Action is executing on server side and server is sending updated component markup to the client which will be morphed into DOM. That's it. To use actions, you need to go through a few steps. You'll need to include a client into page (JS functions for communication) and register an actions handler for a needed component. Let's start from including a client. Then, let's register an actions handler for a needed component. That's all! Now we ready to use actions to provide a dynamic UI. Example: In this example you can see provided modifications to the quick start example. First, we've added a state and name into our components' markup. In this way we are saving our components' state between actions and find a component root. Unfortunately, we have to manually provide a component name for now, we haven't found a way to provide it dynamically. Second, we've added a reload button with onclick function call. We're using a function Action provided by a client. Action triggering will be described in details later. Third, we've added an action handler inside of our component. This handler will be executed when a client calls an action with a corresponding name. It's highly recommended to keep components' state as small as possible. It will be transmitted on each action call. Kyoto have multiple ways to trigger actions. Now we will check them one by one. This is the simplest way to trigger an action. It's just a function call with a referer (usually 'this', f.e. button) as a first argument (used to determine root), action name as a second argument and arguments as a rest.

Package blackfriday is a markdown processor. It translates plain text with simple formatting rules into an AST, which can then be further processed to HTML (provided by Blackfriday itself) or other formats (provided by the community). The simplest way to invoke Blackfriday is to call the Run function. It will take a text input and produce a text output in HTML (or other format). A slightly more sophisticated way to use Blackfriday is to create a Markdown processor and to call Parse, which returns a syntax tree for the input document. You can leverage Blackfriday's parsing for content extraction from markdown documents. You can assign a custom renderer and set various options to the Markdown processor. If you're interested in calling Blackfriday from command line, see https://github.com/russross/blackfriday-tool. 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 AutoHeadingIDs extension is enabled. The algorithm is specified below, so that other packages can create compatible anchor names and links to those anchors. The algorithm iterates over the input text, interpreted as UTF-8, one Unicode code point (rune) at a time. All runes that are letters (category L) or numbers (category N) are considered valid characters. They are mapped to lower case, and included in the output. All other runes are considered invalid characters. Invalid characters that precede the first valid character, as well as invalid character that follow the last valid character are dropped completely. All other sequences of invalid characters between two valid characters are replaced with a single dash character '-'. 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. It can be useful for clients that want a small package and don't need full functionality of blackfriday.

Vertex is a friendly, fast and flexible RESTful API building framework 1. An API definition framework 2. Request handlers as structs with automatic data mapping 3. Automatic Data Validation 4. An integrated testing framework for your API 5. A middleware framework similar (but not compliant) to negroni 6. Batteries included: JSON rendering, Auto Recover, Static File Serving, Request Logging, and more The basic idea of Vertex revolves around friendly, pre-validated request handlers, that leave the developer with the need to write as little boilerplate code as possible. Routes in the API are mapped to the RequestHandler interface: RequestHandlers have a few interesting characteristics: 1. Fields in structs implementing RequestHandler get automtically filled by request data. 2. Field values are automatically validated and sanitized 3. They do not *(need to)* write to the response writer, they just need to return a response object. You create structs that have all the parameters you need to handle the requests, define validations for these parameters, and Vertex does the rest for you - just return a response object and you're done. Here is an example super simple RequestHandler: As you can see, the "id" parameter that is received as a post/get/path parameter is automatically parsed into the struct when the handler is invoked. If it is missing or invalid, the handler won't even be invoked, but an error will be generated to the client. These are the allowed tags for fields in RequestHandler structs: schema - the parameter name in the request doc - a short documentation string for the field default - the default value for the parameter in case it's missing min - the minimum allowed value for numeric fields (inclusive) max - the maximum allowed value for numeric fields (inclusive) maxlen - the maximal allowed length for strings minlen - the minimal allowed length for strings required true/false - if set to "true", forces the request to have this parameter set allowEmpty true/false - do we allow empty values? pattern - a regular expression that a string must match if this tag is set in query/body/path - optional for non path params. mainly for documentation needs TODO: Support min/max length for string lists Supported types for struct fields are (see : If a field has a custom type that needs automatic deserialization (e.g. a binary Thrift or Protobuf object), we can define a custom Unmarshal method to the type, letting it automatically deserialize parameters. (See the Unmarshaler interface) The unmarshaler should return a new instance of itself with the value set correctly. Example: a type that takes a string and splits in two APIs are defined in a declarative way, preferably separately from defining the the actual handler logic. An API has a few major parts: Here is an example simple API definition: Security Schemes are used to validate requests. The scheme simply receives the request, and returns an error if it is not valid. It can be used to authenticate the user, validate the API key, etc. Vertex comes with some middleware modules included. Currently implemented middleware include: Responses have renderers - that transform the response object to some serialization format. The default is of course JSON, but an HTML renderer using templates also exists. TODO

Package vugu provides core functionality including vugu->go codegen and in-browser DOM syncing running in WebAssembly. See http://www.vugu.org/ Since Vugu projects can have both client-side (running in WebAssembly) as well as server-side functionality many of the items in this package are available in both environments. Some however are either only available or only generally useful in one environment. Common functionality includes the ComponentType interface, and ComponentInst struct corresponding to an instantiated componnet. VGNode and related structs are used to represent a virtual Document Object Model. It is based on golang.org/x/net/html but with additional fields needed for Vugu. Data hashing is performed by ComputeHash() and can be customized by implementing the DataHasher interface. Client-side code uses JSEnv to maintain a render loop and regenerate virtual DOM and efficiently synchronize it with the browser as needed. DOMEvent is a wrapper around events from the browser and EventEnv is used to synchronize data access when writing event handler code that spawns goroutines. Where appropriate, server-side stubs are available so components can be compiled for both client (WebAssembly) and server (server-side rendering and testing). Server-side code can use ParserGo and ParserGoPkg to parse .vugu files and code generate a corresponding .go file. StaticHTMLEnv can be used to generate static HTML, similar to the output of JSEnv but can be run on the server. Supported features are approximately the same minus event handling, unapplicable to static output.

The algorithm iterates over the input text, interpreted as UTF-8, one Unicode code point (rune) at a time. All runes that are letters (category L) or numbers (category N) are considered valid characters. They are mapped to lower case, and included in the output. All other runes are considered invalid characters. Invalid characters that precede the first valid character, as well as invalid character that follow the last valid character are dropped completely. All other sequences of invalid characters between two valid characters are replaced with a single dash character '-'. 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. It can be useful for clients that want a small package and don't need full functionality of blackfriday.

Package blackfriday is a markdown processor. It translates plain text with simple formatting rules into an AST, which can then be further processed to HTML (provided by Blackfriday itself) or other formats (provided by the community). The simplest way to invoke Blackfriday is to call the Run function. It will take a text input and produce a text output in HTML (or other format). A slightly more sophisticated way to use Blackfriday is to create a Markdown processor and to call Parse, which returns a syntax tree for the input document. You can leverage Blackfriday's parsing for content extraction from markdown documents. You can assign a custom renderer and set various options to the Markdown processor. If you're interested in calling Blackfriday from command line, see https://github.com/russross/blackfriday-tool.

Package vugu provides core functionality including vugu->go codegen and in-browser DOM syncing running in WebAssembly. See http://www.vugu.org/ Since Vugu projects can have both client-side (running in WebAssembly) as well as server-side functionality many of the items in this package are available in both environments. Some however are either only available or only generally useful in one environment. Common functionality includes the ComponentType interface, and ComponentInst struct corresponding to an instantiated componnet. VGNode and related structs are used to represent a virtual Document Object Model. It is based on golang.org/x/net/html but with additional fields needed for Vugu. Data hashing is performed by ComputeHash() and can be customized by implementing the DataHasher interface. Client-side code uses JSEnv to maintain a render loop and regenerate virtual DOM and efficiently synchronize it with the browser as needed. DOMEvent is a wrapper around events from the browser and EventEnv is used to synchronize data access when writing event handler code that spawns goroutines. Where appropriate, server-side stubs are available so components can be compiled for both client (WebAssembly) and server (server-side rendering and testing). Server-side code can use ParserGo and ParserGoPkg to parse .vugu files and code generate a corresponding .go file. StaticHTMLEnv can be used to generate static HTML, similar to the output of JSEnv but can be run on the server. Supported features are approximately the same minus event handling, unapplicable to static output.

Package jrpc2client implements client for json-rpc 2.0 protocol and based on another packages: HTTP Client: github.com/valyala/fasthttp JSON Parser: github.com/pquerna/ffjson/ffjson Logger: github.com/sirupsen/logrus Errors: github.com/riftbit/jrpc2errors Example can be found only in client_test.go at this moment You can see your godoc rendered as HTML by running a local godoc server. This is great for previewing your godoc before committing changes. To do that, Make sure your code is in GOPATH and run: Go to http://localhost:8080/pkg and you should see your packages on the list. If you want the raw HTML, you can run:

Vertex is a friendly, fast and flexible RESTful API building framework 1. An API definition framework 2. Request handlers as structs with automatic data mapping 3. Automatic Data Validation 4. An integrated testing framework for your API 5. A middleware framework similar (but not compliant) to negroni 6. Batteries included: JSON rendering, Auto Recover, Static File Serving, Request Logging, and more The basic idea of Vertex revolves around friendly, pre-validated request handlers, that leave the developer with the need to write as little boilerplate code as possible. Routes in the API are mapped to the RequestHandler interface: RequestHandlers have a few interesting characteristics: 1. Fields in structs implementing RequestHandler get automtically filled by request data. 2. Field values are automatically validated and sanitized 3. They do not *(need to)* write to the response writer, they just need to return a response object. You create structs that have all the parameters you need to handle the requests, define validations for these parameters, and Vertex does the rest for you - just return a response object and you're done. Here is an example super simple RequestHandler: As you can see, the "id" parameter that is received as a post/get/path parameter is automatically parsed into the struct when the handler is invoked. If it is missing or invalid, the handler won't even be invoked, but an error will be generated to the client. These are the allowed tags for fields in RequestHandler structs: schema - the parameter name in the request doc - a short documentation string for the field default - the default value for the parameter in case it's missing min - the minimum allowed value for numeric fields (inclusive) max - the maximum allowed value for numeric fields (inclusive) maxlen - the maximal allowed length for strings minlen - the minimal allowed length for strings required true/false - if set to "true", forces the request to have this parameter set allowEmpty true/false - do we allow empty values? pattern - a regular expression that a string must match if this tag is set in query/body/path - optional for non path params. mainly for documentation needs TODO: Support min/max length for string lists Supported types for struct fields are (see : If a field has a custom type that needs automatic deserialization (e.g. a binary Thrift or Protobuf object), we can define a custom Unmarshal method to the type, letting it automatically deserialize parameters. (See the Unmarshaler interface) The unmarshaler should return a new instance of itself with the value set correctly. Example: a type that takes a string and splits in two APIs are defined in a declarative way, preferably separately from defining the the actual handler logic. An API has a few major parts: Here is an example simple API definition: Security Schemes are used to validate requests. The scheme simply receives the request, and returns an error if it is not valid. It can be used to authenticate the user, validate the API key, etc. Vertex comes with some middleware modules included. Currently implemented middleware include: Responses have renderers - that transform the response object to some serialization format. The default is of course JSON, but an HTML renderer using templates also exists. TODO

The simplest way to invoke Blackfriday is to call the Run function. It will take a text input and produce a text output in HTML (or other format). A slightly more sophisticated way to use Blackfriday is to create a Markdown processor and to call Parse, which returns a syntax tree for the input document. You can leverage Blackfriday's parsing for content extraction from markdown documents. You can assign a custom renderer and set various options to the Markdown processor. If you're interested in calling Blackfriday from command line, see https://github.com/russross/blackfriday-tool. 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 AutoHeadingIDs extension is enabled. The algorithm is specified below, so that other packages can create compatible anchor names and links to those anchors. The algorithm iterates over the input text, interpreted as UTF-8, one Unicode code point (rune) at a time. All runes that are letters (category L) or numbers (category N) are considered valid characters. They are mapped to lower case, and included in the output. All other runes are considered invalid characters. Invalid characters that precede the first valid character, as well as invalid character that follow the last valid character are dropped completely. All other sequences of invalid characters between two valid characters are replaced with a single dash character '-'. 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. It can be useful for clients that want a small package and don't need full functionality of blackfriday.
