CLI Usage

# Basic usage
boxlang module:docbox \
    --source=/path/to/source \
    --mapping=myapp \

# With all options
boxlang module:docbox \

# CommandBox (when bx-docbox is installed as a box module)
box docbox generate \
    source=./src \
    mapping=myapp \

Output Formats

Programmatic Usage: HTML Documentation

// Minimal HTML docs
new docbox.DocBox()
    .addStrategy( "HTML", {
        outputDir    : expandPath( "/app/docs/api" ),
        projectTitle : "My Application API"
    })
    .generate(
        source  : expandPath( "/app/models" ),
        mapping : "app.models"
    )

Multiple Strategies (HTML + JSON)

new docbox.DocBox()
    .addStrategy( "HTML", {
        outputDir    : expandPath( "/app/docs/api" ),
        projectTitle : "My Application API",
        theme        : "default"           // "default" or "frames"
    })
    .addStrategy( "JSON", {
        outputDir    : expandPath( "/app/docs/json" ),
        projectTitle : "My Application API"
    })
    .generate(
        source   : expandPath( "/app" ),
        mapping  : "app",
        excludes : "tests,build,node_modules"
    )

Frames Layout Theme

// Traditional JavaDoc-style frames layout
new docbox.DocBox()
    .addStrategy( "HTML", {
        outputDir    : expandPath( "/app/docs" ),
        projectTitle : "My Application API",
        theme        : "frames"
    })
    .generate(
        source  : expandPath( "/app" ),
        mapping : "app"
    )

UML / XMI Output

// Generate StarUML-compatible XMI
new docbox.DocBox()
    .addStrategy( "UML", {
        outputDir    : expandPath( "/app/docs/uml" ),
        projectTitle : "My Application UML"
    })
    .generate(
        source  : expandPath( "/app/models" ),
        mapping : "app.models"
    )

Excluding Directories or Packages

new docbox.DocBox()
    .addStrategy( "HTML", {
        outputDir    : expandPath( "/app/docs/api" ),
        projectTitle : "My Application API"
    })
    .generate(
        source   : expandPath( "/app" ),
        mapping  : "app",
        // Comma-separated paths/packages to exclude
        excludes : "tests,build,app.helpers.internal,app.legacy"
    )

Build Task Integration (Gradle / CommandBox)

// build/DocTask.bx (CommandBox task runner)
component {
    function run() {
        print.line( "Generating API documentation..." )

        new docbox.DocBox()
            .addStrategy( "HTML", {
                outputDir    : expandPath( "../docs/api" ),
                projectTitle : "My Framework API"
            })
            .generate(
                source   : expandPath( "../src" ),
                mapping  : "myframework",
                excludes : "tests"
            )

        print.greenLine( "Documentation generated successfully." )
    }
}

Using Annotations in Source Code

DocBox extracts JavaDoc-style annotations from your BoxLang files:

/**
 * User service for managing application users.
 *
 * @author John Doe
 * @since 1.0.0
 */
class UserService {

    /**
     * Find a user by their ID.
     *
     * @id      The user's unique identifier
     * @return  The user struct or empty struct if not found
     */
    function findById( required numeric id ) {
        // ...
    }
}

Common Pitfalls

• ✅ The mapping must match the dot-notation mapping from your web root to the source directory
• ❌ Don't use absolute OS paths for mapping — use logical component paths (e.g., app.models)
• ✅ Use expandPath() to resolve source and output directories to absolute OS paths
• ❌ Nested addStrategy() calls are fluent — they return the DocBox instance; always call .generate() last
• ✅ The excludes parameter accepts comma-separated path fragments, not regex patterns
• ✅ The HTML "default" theme gives a modern SPA look; "frames" gives a classic JavaDoc layout
