JDSL

Ahead-of-time transpiler for JDSL, the world's most powerful programming language. This super-serious project converts your JDSL code into JavaScript at build-time, so you can skip the runtime overhead[^1] of JDSL.

Inspiration

JDSL, the JSON-based Domain Specific Language, was created by Tom — a genius — to solve some of the world's hardest engineering challenges. These challenges included handling user input, and even updating a database. Things all developers struggled with before the advent of JDSL.

Installation

go install github.com/connerdouglass/jdsl

JDSL Syntax

A JDSL project consists of a series of JSON files. Each file contains a single JSON object, which is a JDSL class. Each class has a name and a series of functions.

Each function is listed as a Git commit hash. The hash is used to look up the contents of a corresponding JS file in the same directory. In that commit, the JS file must contain exactly one function.

To add more functions to a class, simple overwrite the JS file with the new function being added. Commit this change, and take note of the commit hash using git log. Then, add the hash to the JSON file.

See an example project in the example directory.

Usage

Transpile JDSL to JavaScript

Transpiling JDSL to JavaScript is blazingly fast. Just run the following command. The JavaScript output will be written to the dist directory.

jdsl -o dist example/Customers.json example/Main.json

Run JDSL code directly

You can even run your JDSL code directly.

jdsl -r example/Customers.json example/Main.json

Command Line Options

Differences from the original JDSL

• This JDSL transpiler uses Git hashes instead of SVN change numbers. This is due to our technical incompetence.

[^1]: The runtime overhead of JDSL is not a bug, but a feature. Thanks to Tom, rate limiting is a built-in feature of the original JDSL architecture.
