ANGELMARKUP.JS :performing_arts: :guitar: :ribbon:

Simple data storage with no drama in Javascript. :performing_arts: :guitar: :ribbon:

ABOUT :books:

I needed a data format that permits comments for some projects I was working on. Everything else seemed too complicated, so I wrote a compiler and parser for my own data format, called Angel Markup. I iplemented the compiler once in Rust and once in Javascript. This is the Javascript implementation. :heart:

USAGE :hammer:

Use Angelmarkup.js in a Node.js project

To use Angelmarkup.js in a Node.js project, run this command in your project's root directory:

$ npm install --save-dev angelmarkup

Be sure to also add the "type":"module" flag to your project's manifest, package.json.

APIs

Angelmarkup.js offers the following functions:

• toYAML(subject, filler): Converts a map into a YAML string and joins each line with "filler".
• toTOML(subject, filler): Converts a map into a TOML string and joins each line with "filler".
• toAML(subject, filler): Converts a map into an AML string and joins each line with "filler".
• toJSON(subject): Converts a map into a JSON string.
• hasIndex(subject, index): Checks if the list "subject" has the index "index".
• class Token(name, value): A class to represent a token. name represents the token's name and value represents the parsed string slice corresponding to a regular expression for that type of token.
• patternPool(): A function that holds the regular expression patterns that represent statements Angelmarkup.js understands.
• lexSrc(source, pool): A lexing function to take a string, run my algorithm for lexing, and return a list of tokens. (I deliberately made the arguments customizable for easy re-use.)
• serializeAML: A function that parses Angel Markup statements and serializes them into a map.
• testAll(): Tests all of the above.

Angel Markup Syntax

Angel Markup is very simple. It is similar to JSON and only recognizes one data type. This data type is a string. Here's a small example.

# This is a comment.
# Assigns the "name" field, the value "max".
'name' => 'max'

Example

Here's a small example:

• 1.) Initialize a new Node.js project with the following command in a directory of your choosing:

$ npm init -y 

• 2.) Install Angelmarkup.js as a dependency:

$ npm install --save-dev angelmarkup

• 3.) Be sure to add this line to your project's package.json:

"type":"module",

• 4.) Create your index.js file and put the following code inside it:

// index.js
import * as angelmarkup from 'angelmarkup';

function main(){
  // A string of an AML key-value pair.
  var amlTestString = "'name' => 'aml'";
  // The parsed string as a map.
  var serialized = angelmarkup.serializeAML(amlTestString);
  // Printing out the resulting map.
  console.log(serialized);
}

// Calling the "main" function.
main();

• 5.) Run the project:

$ node .

• 6.) Should print out this:

Map(1) { 'name' => 'aml' }

• 7.) If you're still not sure how to use this, check out the example project in the example folder.
