Parses the song info & lyrics from various lyric presentation software file formats. You can convert between different formats and download the converted files.

• ✅ = Supported
• ⭕ = Not supported (yet?)
• ❓ = Unknown/Untested
• 💾 = You can import the ProPresenter 6 files made by LyricConverter into ProPresenter 7!

• martijnversluis/ChordSheetJS

• Microsoft/TypeScript
• Angular/angular
• NaturalIntelligence/fast-xml-parser
• eligrey/FileSaver.js

• Deal with possibly duplicated info keys
• Allow user-configurable options for output file (resolution, text size, etc)

Want to help out and improve LyricConverter? Thanks! You'll need to be familiar with Angular and TypeScript, which are needed to run this project. Run npm install @angular/cli typescript -g to install the global tools you'll need.

Clone this project and run npm install. Afterwards run ng serve to start the development server, you can see it running at http://localhost:4200/. The application will automatically reload if you change any of the source files.

I recommend you use VSCode and install the recommended extensions when you open this project in it.

• In VSCode press Alt+Shift+F to run the Prettier code formatter.
• Run ng lint to report on any potential code issues
• Run ng test to run the unit tests. Please add tests for any new features or changes you make.
• Run npm run test-coverage to generate a test coverage report. View the generated /coverage/lyric-converter/index.html file to see specifics about uncovered areas of code if needed.

• Run ng build to build the project in production mode which is stored in the dist/ directory.
• Run npm run prerender to generate the prerendered HTML pages for each route - this is what is deployed to production

Anything added to this project will most likely be a new format for LyricConverter to either be able to read or write. So all you need to worry about is dealing with the inputs and outputs which are generalized TypeScript classes and not specific to the Angular framework at all.

• Arrays of all available input types and output types are kept in the ParserService at /app/convert/parser/parser.service.ts for the Angular app to manage.
• Lyric converter will take any files passed to it and run them each through all of the input types available to it.
  • All input types are classes in the /app/convert/inputs/* folder that implement the IInputConverter interface.
  • Files are passed to the doesInputFileMatchThisType() method which returns a boolean. Typically this only needs to check the file extension for most file types.
  • Once each incoming file type is known, it will use the extractSongData() method to get the song information and lyrics converted to a generic ISong format.
• Once all songs are in ISong format, all of these objects are passed to the output type that the user has selected
  • All output types are classes in the /app/convert/outputs/* folder that implement the IOutputConverter interface.
  • The ISong representation of the song is passed to convertToType() which manipulates it into a string representation of the file content for whatever the desired format is
  • That string is then put into an IOutputFile object and passed along to the UI for conversion to a real file to be downloaded

• Open the /app/convert/inputs/ directory in your command line (in VSCode right click the folder > "Open in integrated terminal") and run ng generate class input-type-whatever and Angular will generate a new class file named input-type-whatever.ts and a test file input-type-whatever.spec.ts
• Open the newly generated TS file and make the class export class InputTypeWhatever implements IInputConverter and add the required properties and methods
• Open the ParserService at /app/convert/parser/parser.service.ts and add this new input type to the inputConverters array
• Look at other existing input types to get an idea of how these work. Basically you will need to manipulate the incoming data to extract the song info and the lyrics into the ISong format.
• Add tests to verify that this new input type can convert all kinds of variations of songs in whatever format this is into an ISong object

• Open the /app/convert/outputs/ directory in your command line (in VSCode right click the folder > "Open in integrated terminal") and run ng generate class output-type-whatever and Angular will generate a new class file named output-type-whatever.ts and a test file output-type-whatever.spec.ts
• Open the newly generated TS file and make the class export class OutputTypeWhatever implements IOutputConverter and add the required properties and methods
• Open the ParserService at /app/convert/parser/parser.service.ts and add this new input type to the outputConverters array
• Look at other existing output types to get an idea of how these work. Basically you will need to take the incoming ISong object and create a string representation of whatever the file content of this format looks like and pass that off as an IOutputFile object. Add tests to verify that this new output type can take all kinds of ISong objects and convert them to the expected output string
