Transform DSL (Lingvo Dictionary File) files to JSON. Formatting options available for custom output.
There are many dictionaries available as .dsl, but very few in easily consumable formats. Harlaw formats the dsl files to json with decent search/replace/remove options.
Also available for Rust
yarn add harlaw
With default settings:
const { toJson } = require('harlaw');
const input = `${__dirname}/dsl/myDictionary.dsl`
const output = `${__dirname}/json/myResult.json`
await toJson(input, output);By default, Harlaw performs HTML transform to Lingvo markup. For example, [b] becomes <strong/> and [i] becomes <i>.
You can also pass on settings array to remove all extra markup:
const { toJson, noMarkupSettings } = require('harlaw');
const input = `${__dirname}/dsl/myDictionary.dsl`
const output = `${__dirname}/json/myResult.json`
await toJson(input, output, noMarkupSettings)For custom formatting needs, you can also pass on completely custom settings object:
const { toJson } = require('harlaw');
const input = `${__dirname}/dsl/myDictionary.dsl`
const output = `${__dirname}/json/myResult.json`
const mySettings = {
replaces: [ // Any key & value pair you with replaced.
{ search: '[b]', replace: '<strong>' },
{ search: '[/b]', replace: '</strong>' },
{ search: '[i]', replace: '<i>' },
{ search: '[/i]', replace: '</i>' },
{ search: '[p]', replace: '<span>' },
{ search: '[/p]', replace: '</span>' },
{ search: '{-}', replace: '-' },
{ search: '[ref]', replace: '<span class="reference">' },
{ search: '[/ref]', replace: '</span>' },
],
removes: [ // Any elements to be replaced with ''
'\\', '[/m]', '[m1]', '[m2]', '[m3]', '[m4]', '[m5]', '[m6]', '[m7]', '[m8]', '[m9]', '[m10]', '\t', '[u]', '[/u]',
],
}
await toJson(input, output, mySettings)If you don't want physical json file, but would rather just do something with data, use toArray
const { toArray } = require('harlaw');
const input = `${__dirname}/dsl/myDictionary.dsl`
const mySettings = {
//optional
}
const dictionary = await toArray(input, mySettings)
console.log(dictionary)Sometimes default settings for Node do not parse files correctly. For example, the file might be encoded in non-standard format. This might mean you need to pass custom settings for file reading.
You can use custom read options by passing readOptions object to settings. It will be passed to createReadStream.
const { toJson, toArray } = require('harlaw');
const input = `${__dirname}/dsl/myDictionary.dsl`
const output = `${__dirname}/json/myResult.json`
const mySettings = {
replaces: { /* optional */ },
removes: { /* optional */ },
readSettings: {
encoding: 'utf16le',
// any other valid option.
},
}
// Works with JSON.
await toJson(input, output, mySettings)
// ...And with array.
const dictionary = await toArray(input, mySettings)
console.log(dictionary)In G.R.R Martins "A Song Of Ice And Fire", there is a character named Rodrik Harlaw. He is mockingly called "The Reader". That is what my Harlaw does too; reads things no one else cares about.
