MarkWahlberg

A templating engine for complex data inside Github Markdown documents. It's not markup, it's not Markdown, it's MarkWahlberg.

Getting started

Run npm install mark-wahlberg

What is a MarkWahlberg template?

Glad you asked. A template is just a string, optionally in Markdown syntax, containing zero or more embedded data points. This is a template:

When you go to the store, remember to pick up 4 gallons of milk.

Now, it doesn't contain any embedded objectts, but it is a template. A template with MarkWahlberg-embedded information would be

When you go to the ${{name: milkPlace, type: STRING, defaultValue: 'store'}}, 
remember to pick up ${{name: milkGallonsCount, type: NUMBER, defaultValue: 4}} gallons of
milk.

Disregarding why you'd need that much milk, there are 2 variables embedded in this template:

1. milkPlace, whose type is STRING and whose default value is 'store'
2. milkGallonsCount, whose type is NUMBER and whose default value is 4

API

MarkTemplate Class

constructor(templateString: string)

template.getVariables() => MarkVariable[]

template.getVariable(name: string) => MarkVariable | null

template.serialize() => string[]

MarkVariable Class

constructor(variableString: string)

If you must create your own MarkVariable instances, use this constructor. Always use MarkVariable.isValidVariableString() before using it in the constructor -- if an invalid string is passed, it will throw a TypeError.

let variable;
const variableStr = '${{name: foo, type: NUMBER, defaultValue: 1}}'
if (MarkVariable.isValidVariableString(variableStr)){
  variable = new MarkVariable(variableStr);
}

MarkVariable.isValidVariableString(str: string) => boolean

Use this function to check whether a string is a valid MarkVariable. Always use this function if you are creating a MarkVariable by yourself.

const validStr = '${{name: foo, type: NUMBER, defaultValue: 1}}'
const invalidStr = '$(name: foo, type: NUMBER,)';

MarkVariable.isValidVariableString(validStr); // true
MarkVariable.isValidVariableString(invalidStr); // false

Should I use this in my production application?

Not yet. There are still a lot of kinks to be worked out and security to be tightened up. Obviously feel free to use this an experimental way or contribute to development 😊. v1.0.0 will be released when it's ready to be used in production.
