SourceDocs

SourceDocs is a command line tool that generates markdown documentation files from inline source code comments.

Similar to Sphinx or Jazzy, SourceDocs parses your Swift source code and generates beautiful reference documentation. In contrast to those other tools, SourceDocs generates markdown files that you can store and browse inline within your project repository. Or even render with GitHub Pages.

Features

• ✅ Generate reference documentation from Xcode projects
• ✅ Generate reference documentation from Swift Packages
• ✅ Generate package description documentation from Swift Packages

Generated documentation

SourceDocs writes documentation files to the Documentation/Reference directory relative to your project root (path can be configured). This allows for the generated documentation to live along other hand-crafted documentation you might have written or will write in the future.

When specifying a module name, the documentation files will be written to Documentation/Reference/<module name>.

It's recommended adding this generated documentation to the source code repository, so it can be easily browsed inline. GitHub, BitBucket and other source control platforms do a great job rendering Markdown files, so documentation is easy to read.

Examples of Generated Documentation

• SourceDocsLib
• SourceDocsDemo
• SourceDocs Package
• Apollo iOS API Reference
• Workflow framework (by Square)

Requirements

Usage

Swift Packages

To generate documentation for a Swift Package, run sourcedocs from the root of your package repository.

$ cd path/to/MyPackage
$ sourcedocs generate --all-modules

This command will generate documentation for each module in your Swift package.

For a specific module, pass the module name using the --spm-module parameter.

$ sourcedocs generate --spm-module SourceDocsDemo

Xcode Projects

To generate documentation from your source code, run sourcedocs directly from the root your Xcode project.

$ cd path/to/MyAppOrFramework
$ sourcedocs generate

This command will analyze your Xcode project and generate reference documentation from all public types found.

Usually, for most Xcode projects, no parameters are needed at all. xcodebuild should be able to find the default project and scheme.

If the command fails, try specifying the scheme (-scheme SchemeName) or the workspace. Any arguments passed to sourcedocs after -- will be passed to xcodebuild without modification.

$ sourcedocs generate -- -scheme MyScheme

Usage options

Typing sourcedocs help we get a list of all available commands:

$ sourcedocs help
USAGE: source-docs <subcommand>

OPTIONS:
  -h, --help              Show help information.

SUBCOMMANDS:
  clean                   Delete the output folder and quit.
  generate                Generates the Markdown documentation
  package                 Generate PACKAGE.md from Swift package description.
  version                 Display the current version of SourceDocs

Typing sourcedocs help <command> we get a list of all options for that command:

$ sourcedocs generate --help

OVERVIEW: Generates the Markdown documentation

USAGE: source-docs generate <options>

ARGUMENTS:
  <xcode-arguments>       List of arguments to pass to xcodebuild 

OPTIONS:
  -a, --all-modules       Generate documentation for all modules in a Swift package 
  --spm-module <spm-module>
                          Generate documentation for Swift Package Manager module 
  --module-name <module-name>
                          Generate documentation for a Swift module 
  --link-beginning <link-beginning>
                          The text to begin links with 
  --link-ending <link-ending>
                          The text to end links with (default: .md)
  -i, --input-folder <input-folder>
                          Path to the input directory (default: /Users/ramses.alonso/Development/eneko/SourceDocs)
  -o, --output-folder <output-folder>
                          Output directory to clean (default: Documentation/Reference)
  --min-acl <min-acl>     Access level to include in documentation [private, fileprivate, internal, public, open] (default: public)
  -m, --module-name-path  Include the module name as part of the output folder path 
  -c, --clean             Delete output folder before generating documentation 
  -l, --collapsible       Put methods, properties and enum cases inside collapsible blocks 
  -t, --table-of-contents Generate a table of contents with properties and methods for each type
  -s, --skip-empty        Do not generate documentation for files with no comments. 
  -r, --reproducible-docs Generate documentation that is reproducible: only depends on the sources.
                          For example, this will avoid adding timestamps on the generated files. 
  -h, --help              Show help information
