OpenAPI / Swagger / AsyncAPI / Semoasa definition to Slate / Shins compatible markdown

Build

Widdershins adverb:

In a direction contrary to the sun's course;
anticlockwise;
helping you produce static documentation from your OpenAPI 3.0 / Swagger 2.0 / AsyncAPI 1.x / Semoasa 0.1.0 definition

News

As of v3.0.0 Widdershins no longer expands the definition of OpenAPI body parameters / requestBodies by default, unless they have an inline schema. You can restore the old behaviour by using the --expandBody option.
You may limit the depth of schema examples using the --maxDepth option. The default is 10.
To omit schemas entirely, please copy and customise the main.dot template.
As of v3.x you must use the --harmony flag if running on Node.js 4

To install

Clone the git repository, or
npm install [-g] widdershins, or
yarn global add widdershins

var converter = require('widdershins');
var options = {}; // defaults shown
options.codeSamples = true;
//options.language_tabs = [];
//options.loadedFrom = sourceUrl;
//options.user_templates = './user_templates';
options.templateCallback = function(templateName,stage,data) { return data };
options.theme = 'darkula';
options.search = true;
options.sample = true; // set false by --raw
options.schema = true; // set false by --noschema
options.discovery = false;
options.includes = [];
options.summary = false;
options.headings = 2;
converter.convert(apiObj,options,function(err,str){
  // str contains the converted markdown
});

The headings option is currently only supported by Shins, not Slate which lacks this feature.

To only include a subset of the pre-defined language-tabs, or to rename their display-names, you can override the options.language_tabs:

options.language_tabs = [{ 'http': 'HTTP' }, { 'javascript': 'JavaScript' }, { 'javascript--nodejs': 'Node.JS' }, { 'python': 'Python' }, { 'ruby': 'Ruby' }];

If you need to support a version of Slate <v1.5.0 (or a renderer which also doesn't support display-names for language-tabs, such as node-slate, slate-node or whiteboard), you can use the --environment option with the included whiteboard_env.json file to simply achieve this.

The loadedFrom option is only needed where the OpenAPI / Swagger definition does not specify a host, and (as per the OpenAPI specification) the API endpoint is deemed to be based on the source URL the definition was loaded from.

Note that the list of included files is simply passed into the header of the markdown file, they are actually included by Slate or the alternative you use.

Schema.org WebAPI discovery data is included if the discovery option above is set true. See the W3C WebAPI Discovery Community Group for more information.

Language tabs

Widdershins supports the x-code-samples vendor-extension to completely customise your documentation. Alternatively, you can edit the default code-samples in the templates sub-directory, or override them using the user_templates option to specify a directory containing your templates.

Widdershins supports the use of multiple language tabs with the same language (i.e. plain Javascript and Node.Js). To use this support you must be using Slate (or one of its ports compatible with) version 1.5.0 or higher. Shins versions track Slate version numbers.

Template parameters

Templates are compiled with doT.js.

Templates have access to a data object with a range of properties based on the document context.

If you specify an options.templateCallback function, it will be called before and after each template, with three parameters, the template name, the stage, ('pre' or 'post') and the current data object. You can mutate the data object in any way you see fit, as long as you return it. Content in the data.append property will be appended to the current output stream.

User templates

To override a .dot template, you need to copy over the child .def partials as well.

To override a .def partial, you need to copy over the parent .dot template as well. For OpenAPI 3 this will be main.dot except for parameters, responses and callbacks, which are children of the operation.dot template.

This means it is usually easiest to copy all .dot and .def files to your user templates directory. A visual diff tool which can run across two directories (such as Meld or WinMerge) may be useful in bringing in changes from Widdershins updates.

Tests

To run a test-suite:

node testRunner {path-to-APIs}

The test harness currently expects .yaml or .json files and has been tested against
