TI-JS lets you run TI-Basic programs in the browser (by acting as a compiler/runtime, not through emulation).
Currently working on expanding the grammar, so this is in prerelease.
Check out the project page and the test suite, or playground.
TI-JS releases are available via npm.
For developing, see the CONTRIBUTING.md.
If you've got a package.json, you'll want to install first:
npm install ti-jsHow you then import it depends on the platform you're developing for. See the table below:
| platform | CommonJS | ES6 |
|---|---|---|
| node | require('ti-js') |
import * as ti from 'ti-js' |
| web | const ti = require('ti-js/dist/web/ti') |
import * as ti from 'ti-js/dist/web/ti' |
See sample directories for examples.
If you've just got a static webpage, you can import the library like so:
<script
src="https://cdn.jsdelivr.net/npm/ti-js@latest/dist/web/ti.min.js"
crossorigin="anonymous"></script>Note that you can specify the version you want instead of using latest.
Then just declare ti as global in your scripts and use it:
/* global ti */See the docs directory for example webpages.
Note: In progress! This library is still in pre-release.
This library doesn't support TI-BASIC exactly, but an ASCII-fied version of it.
Furthermore, not all commands are implemented yet.
To see which commands are available, refer to the table in ROADMAP.md.
The interface is still in progress, but here's two ways you can use the library.
Porcelain
The simplest way to use the library is the exec command, which runs
a TI-Basic program, collects the output, and passes it to a specified callback.
ti.exec('Disp "hello world"', output => {
document.body.innerHTML += output
})Plumbing
If you want more control over the runtime, use the parse and run commands
directly. This will let you inspect the running program and redirect the output
wherever you like.
const lines = ti.parse(source)
program = ti.run(lines, {
elem: $output,
})
