grokdb

Flashcard app to help you grok better. WORK IN PROGRESS.

This app is currently in heavy development; and all commits will be squashed for the initial public consumption.

Usage

Run from your terminal:

$ grokdb [options] <database name>

Access the client from your favourite browser (assuming port 8080): http://localhost:8080/

Options

 --port, -p "8080"    Port number to serve
 --mathjax            Alternative source folder of MathJax to serve
 --app                Alternative source folder of app to serve
 --help, -h           Show help
 --version, -v        Print the version

MathJax

markdown-it is being used for Markdown parsing/rendering.

LaTeX math can be used anywhere where Markdown can be parsed/rendered. For example:

$$\zeta(s) = \sum_{n=1}^\infty \frac{1}{n^s}$$

MathJax is used to render these math markup. The actual MathJax source library is not bundled with grokdb since it is fairly large (>100 MB in size). Instead the source is fetched via the Internet through the following CDN link: https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML

The default MathJax configuration is enforced: TeX-AMS-MML_HTMLorMML. (This may be configurable in the future.)

local copy of MathJax

As an alternative, you may choose to have grokdb use a local copy of MathJax:

  1. Download the source: https://github.com/mathjax/MathJax/releases
  2. Extract.
  3. Run grokdb --mathjax=path/to/folder <database name> (modify with additional options as necessary)

This is very useful for when Internet access is spotty or not available.

Alternative app

When running grokdb, it acts like a REST api (courtesy of gin). So you can modify the database through it using your favourite REST client (e.g. HTTPie).

You can have grokdb serve an alternative application directory rather than the bundled app:

grokdb --app=path/to/app <database name>

Card Performance

The card's performance is measured using binary votes (successes and fails) that are akin to Reddit upvotes/downvotes.

The calculation of this score is based on the following references:

All cards are ranked based on this score and as well as the date and time that they were last reviewed.

Development

cd client/
webpack -p
cd ..
./buildassets.sh
go build
