Writing loaders

First initialize a folder as a nodejs package. Its name should follow meml-loader-[Language name]. Add the following code to the file.

class Loader {

// -----------------------------------------------------------------------------

// Configuration variables

// Configuration variables

supportsWebImport = false

supportsLocalImport = false

supportsDestructureImport = false

supportContentImport = false

// A regexp that matches against the file extension

fileMatch = new RegExp('.+\\.foo')

// The name of your file loader

name = 'meml-loader-[Language name]'

// -----------------------------------------------------------------------------

// Import functions

//

// Note: all import functions must be async or error out when called

// Destructure imports

// (import (something1, something2) from 'somefile')

//

// Expected to return Promise<Map<string, string | ComponentDefinition>>

webDestructureImport(pathContents, path, toImport, production) {

throw new Error('Method not implemented.')

}

// Content Import

// (import 'somefile')

//

// Expected to return Promise<string>

webContentImport(pathContents, path, production) {

throw new Error('Method not implemented.')

}

// Destructure imports

// (import (something1, something2) from 'somefile')

//

// Expected to return Promise<Map<string, string | ComponentDefinition>>

localDestructureImport(pathContents, path, toImport, production) {

throw new Error('Method not implemented.')

}

// Content Import

// (import 'somefile')

//

// Expected to return Promise<string>

async localContentImport(pathContents, path, production) {

return pathContents

}

}

Then export it as MEMLLoader:

module.exports = {

MEMLLoader: Loader,

}
