# Wordle Assistant



A Wordle solver running on ABAP transpiled into JS



## Solution



The application is available at [https://wordle.marcbernardtools.com](https://wordle.marcbernardtools.com).

## Design



The solution is based on [Zwordle](https://github.com/hdegroot/zwordle) by Huge de Groot. The original code was adjusted slightly to be compatible with [Open-ABAP](https://github.com/open-abap/open-abap). This ABAP code was then transpiled into JavaScript using the [ABAP to JS transpiler](https://github.com/abaplint/transpiler). Some placeholders were added for passing user input to this JS code. Finally, the 

JS code was bundled together with the [abaplint runtime](https://github.com/abaplint/abaplint) using [browserify](https://browserify.org/). The resulting website consists of only three files: One for HTML, one for JavaScript, and one for the Favicon.



## How To



I took the original [Zwordle code](https://github.com/hdegroot/zwordle/blob/main/src/zwordle.prog.abap) and placed it into an ABAP class. The input parameters of the main class method represent the selection-screen parameters of the original program. This [code](https://github.com/Marc-Bernard-Tools/Wordle-on-ABAP/blob/main/abap/zwordle.abap) is now compatible with Open-ABAP.



Next, I pasted the Open-ABAP code into the [ABAP to JS transpiler playground](https://transpiler.abaplint.org/) and captured the resulting JavaScript code from the middle panel. It's certainly possible to incorporate this transpilation step into the website as well, but here the ABAP code and therefore the resulting JavaScript won't change. So, why bother?



To link the input from the website to the transpiled ABAP code, I added some placeholders into the method call (see `$$var$$` [here](https://github.com/Marc-Bernard-Tools/Wordle-Assistant/blob/c7559bc6f7acc7b4a56df46ee4898e7fdd6870af/abap/abap.js#L392-L400)). These placeholders will be replaced by the user input using [JavaScript](https://github.com/Marc-Bernard-Tools/Wordle-Assistant/blob/c7559bc6f7acc7b4a56df46ee4898e7fdd6870af/main.js#L15-L30).



When the user clicks the button or hits enter, it will [execute the Open-ABAP code and return the console output](https://github.com/Marc-Bernard-Tools/Wordle-Assistant/blob/c7559bc6f7acc7b4a56df46ee4898e7fdd6870af/main.js#L32-L45) to the HTML page.  



Finally, I used [browserify](https://github.com/Marc-Bernard-Tools/Wordle-Assistant/blob/70946c35ccef70818c95f7fa8207e2163214c4c5/package.json#L8-L10) to bundle the JS of this app and the abaplint runtime together into a [single JS file](https://github.com/Marc-Bernard-Tools/Wordle-Assistant/blob/main/dist/bundle.js) which is embedded in the [HTML page](https://github.com/Marc-Bernard-Tools/Wordle-Assistant/blob/main/index.html).



## Build Yourself



1. Clone this repo

2. Run `npm install`

  Optionally:

  - Edit `index.html`, `main.js`, or `abap/zwordle.abap` 

  - Transpile `zwordle.abap` into `abap/abap.js` (if ABAP has changed)

  - Add placeholders to `abap/abap.js` (see above)

3. Edit `node_modules\@abaplint\runtime\build\src\statements\index.js` and remove the dependency on node built-in `util/types` (remove `const types_1 ...` and its usage)

4. Bundle the app with `npm run build`

5. Copy `index.html`, `dist/bundle.js`, and `favicon.ico` to your host (or use GitHub pages)
