ohayo v19.2.0

Ohayo

Ohayo is a fast and free tool for data science. Ohayo consists of a very high level programming language and a visual web studio for that language.

You can try ohayo at https://ohayo.computer, download Ohayo on GitHub, try Ohayo hosted on GitHub, or install it using npm install ohayo.

Mission

Let's make it faster to do data science. Much faster. So fast that you can do data science as fast as you can speak.

Key Concepts

OhayoLang Ohayo the language is a Tree Language, built using Tree Notation. Ohayo is a dataflow language.

Scripts OhayoLang is a scripting language like any other and you can write programs in it by hand or using the Ohayo Studio. OhayoLang scripts generally have the file extension ".ohayo".

Tiles An Ohayo program is composed of Tiles. Tiles can display UI to the user. Tiles are recursive and can be the parent of other tiles. Tiles are namespaced and all must contain at least one ".".

Tile Properties Tiles can define and use their own Properties. The names of Tile Properties cannot contain a ".".

DataTables All Tiles can access the tables of their ancestor tiles and also pass on a new table to their descendants. The data tables currently use the jTable library.

Common Tile Types All Tiles extend from a base class. The three most common core Tile Types are Provider, Transformer, and Chart. In data science you have 3 main kinds of things: datasets, data transformations, and visualizations. Datasets include everything from weather forecasts to emails to business transactions. There are millions of possible datasets. In Ohayo tiles that provide datasets generally extend the Provider base tile type. Transformations are things like filtering, grouping, and joining. In Ohayo tiles that transform data generally extend the Transformer tile type. Charts include bar charts, line charts, scatterplots and word clouds. In Ohayo charts generally extend the Chart base tile type.

Creating Tiles If you need a new tile—to add a new user friendly data source or visualization type, for example—you can implement it using TypeScript/Javascript/Grammar language. See the packages folder for examples. Documentation for this will come out later in 2020.

BETA!

Ohayo is still beta and iterating frequently. Post feedback here or on the Ohayo subreddit. Ohayo hopefully will be stable by July 2020.

Marketing Jumbo

If you are looking for some marketing-speak, here you go:

1. The simplest syntax possible. No parentheses, no brackets, no semicolons. Just words you can speak.
2. Write by hand or program visually. The first visual editor that generates perfectly clean code.
3. Autocomplete like you've never seen before. AI powered autocomplete that keeps getting better.
4. Free and open source. The price is $0, and extensions and collaboration are welcome.
5. No installing required. Run Ohayo instantly in your browser, even on your mobile device.
6. No tracking, no cookies. Ohayo doesn't track users, use cookies, or store your data.
7. Secure by design. Your data stays on your machines, we never see it.
8. Runs anywhere. Run it from our sites, host it yourself, or run it on your local machine.
