Using the Templating package

This package contains the basic templating infrastructure, as well as utilities and base classes for creating custom code writers and model transforms for Yellicode.

In order to run a code generation template, you must have the CLI installed (@yellicode/cli) and have a valid codegenconfig.json file. Please refer to the installation instructions and the quick start for more.

Very basic usage - without code model

import { Generator, TextWriter } from '@yellicode/templating';

Generator.generate({outputFile: './my-file.txt'}, (writer: TextWriter) => {
    writer.writeLine('File generated at '+new Date().toISOString());
}); 

Basic usage - with code model

When generating code from a code model, you should at least install the Model package (@yellicode/model). The template structure should be as follows:

import { Generator, TextWriter } from '@yellicode/templating';
import * as model from '@yellicode/model';

Generator.generateFromModel({outputFile: './my-file.txt'}, (writer: TextWriter, model: model.Package) => {
    // Enumerate classes
    model.getAllClasses().forEach((c) => {
        // Write a class definition here...
        // Enumerate attributes
        c.ownedAttributes.forEach(att => {
            // Write the attribute definition here...
        });                
    })
});     

Generating multiple files with a single template

import { Generator, TextWriter } from '@yellicode/templating';
import * as model from '@yellicode/model';

Generator.getModel().then((model: model.Model) => {
    // Generate a file for each class in the model  
    model.getAllClasses().forEach((c) => {
        Generator.generate({ outputFile: `${c.name}.txt` }, (writer: TextWriter) => {
            writer.writeLine(`/* This file contains the code for class '${c.name}'. */`);
        });
    });
})
