TSCE

A TypeScript to Emacs Lisp transpiler

Usage

Creating a new project

To create a new project, create a new folder to act as the project root folder and run the following command in it:

tsce init <projectName>

This gives a folder structure as follows:

- rootFolder
    - tsconfig.json
    - src
        - <projectName>.ts
    - dist

Compiling project

Compile the project by running:

tsce <path to tsconfig.json>

or just

tsce

in the project root folder.

The output of the compile will then appear in the dist folder.

Creating release

cd tsce
tsc
npm pack

Missing language features

• classes
• async/await
• namespaces
• for-in statements
• npm
• switch statements

Dependencies

Requires Emacs version >=25.1 and NodeJS

Why?

I wanted to write more emacs packages, but I prefer working with static type checking. TypeScript has a flexible enough type system that it could be viable as a compiler frontend for elisp, and the typescript compiler API is very accessible.

Goals (short term)

• Convert a large enough subset of TypeScript to Elisp to be usefull in the creation of new packages.
• Output readable Elisp code.

Stretch goals

• Support, if possible, the entire TypeScript language
