# LearnWords2
A vocabulary learning component for flash cards implementing the Leitner system

## Aim

The aim of the project is twofold
1. Provide a JavaScript library called ``LW.js`` which maintains and uses a collection of vocabulary questions in a database. "Database" means here JSON data to be kept in the localStorage. A simple demo GUI is provided which illustrates how  ``LW.js`` is to be set up and used.
2. Provide data conversion and report functions for lists of words to learn (the JSON files). This includes the conversion to the [Anki](https://apps.ankiweb.net/) file format.

## What does the library ``LW.js`` implement?
The library offers a learning session which means that a certain number of questions is asked. The number is specified by a setting value. There are questions in the database which have never been asked, questions which are to be _learned_ and questions which are to be reviewed.

A vocabulary question for review is  picked at random and then depending on the answer a new date is noted for the question to be asked again. The time interval increases if the question has been answered correctly. To do this a step (or level) value is maintained for each question to determine the time period after which the question might be asked again.

This is known as [spaced repetition](https://en.wikipedia.org/wiki/Spaced_repetition).

It is as well possible to do the selection of questions according to tags given to each vocabulary entry.

The library implements the two lower levels as shown in the diagram:

## Reports

This repository includes [CLI](https://en.wikipedia.org/wiki/Command-line_interface) programs to generate HTML and LibreOffice Draw reports for  flash cards to be printed.

# Setup and usage

## Installation of the development environment

Installation of LearnWords2 repository

````	
git clone https://github.com/hhzl/LearnWords2.git
cd LearnWords2
npm install
grunt
````

Note: 
The ``grunt`` command generates the files in the ``dist`` directory. These JavaScript files are the debug and minified versions of the LearnWords2 library (``dist/LW.js`` and ``dist/LW-debug.js``). They are copied to the ``public/js`` directory so the demo and Jasmine tests are using the "latest version" (i.e. derived from the JavaScript in ``src``) of the library. The directory `public/data/json` contains the output data to be used by the library.

Note2:
The generation of the browser version of the jasmine tests is currently disabled. Just use
````
    jasmine
````
to run the tests on the command line.

Draft of more documentation [here](https://github.com/hhzl/LearnWords2/blob/master/docs/Developer_notes.md#2018-01-30).

## Use of the library ``LW.js`` in client program

To use the library you just need to copy ``LW.js`` to the code repo of your app and add it as follows.

```
<script src="pathTo/LW.js"></script>
```
The file ``public/demo.html`` illustrates this.

## API 2 of ``LW.js``

![learnwords2-layers](https://raw.githubusercontent.com/hhzl/LearnWords2/master/docs/learnwords2-layers.png)

- LWdb is the data access layer.
- LWBoxOfQuestions contains the logic for "accessing and moving the cards" (e.g. voculary entries) in the Leitner box

Code:

````JavaScript
"use strict";
var lw = function(){

var db = LW.LWdb('learnWords');

var box = LW.BoxOfQuestions(db);
         
        // configuration

.......

box.importFrom(wordlist);

return box;
}();

````

The construction above (IIFE) returns the BoxOfQuestions object ready for use.

If there is no configuration of the db you could as well just do

````JavaScript
var lw = LW.BoxOfQuestions(LW.LWdb('learnWords'));
    lw.importFrom(wordlist);

````

Then access to everything goes through  ``lw.method()``.

````JavaScript

lw.importFrom(....);

lw.question();

lw.answer();
lw.answerOptions();

lw.moveQuestionBackwards();

lw.moveQuestionForward();

````

Note: If `lw.moveQuestionBackwards()` and `lw.moveQuestionForward()` are called repeatedly on the same question it has only an effect the first time. The next time `lw.question()` is called a new question is provided.

TODO: Add more usage examples and link to the full API description.

## Input data

Input data are CSV files with words and pictures in the directory `data/csv`.

## Export data

Export data in as HTML report and Anki database are generated and put into `public/data`.
The data to be used by the library is in `public/data/json`.

## Specification and tests with Jasmine

### In the browser

- on the command line do

```
     grunt
     ```

- then a browser window will launch and bring you to a Jasmine test harness page
  which is usually [http://localhost:8000](http://localhost:8000)

### On the command line with node

npm test

## Credits

Anatol Marezhanyi, for the https://github.com/e1r0nd/LearnWords project
which implements data storage, Leitner box mechanism and a GUI. That project is under reconstruction.

This project here is based on ideas and originally on code from LearnWords but has a different aim:
1. It implements the non-gui part only to allow other projects to use the [SRS](https://github.com/repeat-space/srs-knowledge) and datastorage part as a library
2. It adds data conversion functions to be used through a CLI for word list preparation and production of printed flash cards.
3. Most of it is rewritten.
4. It uses Jasmine tests.

## Status

* Jasmine specs are set up and work both in the browser and on the command line.
* The LWdb (database layer) specification is set up and implemented with an MVP set of specs. 
* [release 0.2.2-beta](https://github.com/hhzl/LearnWords2/releases/tag/v0.2.2-beta) has a MVP implementation for the Leitner box and may be used for development work.
* Documentation [update](https://github.com/hhzl/LearnWords2/blob/master/docs/Developer_notes.md) in progress
* release 0.3.1 will come soon.
