Mirror

Utility functions for reflection on TS files. Mainly for use as a Bun macro to do some meta programming.

Usage

We can use it as a Bun plugin or a macro. See src/example.ts.

a. Bun plugin

bun --preload preload.ts

preload.ts

import {plugin} from 'bun'
import {bunPluginLive} from '@live/compiler/bun-plugin'

// Must be referenced or it is shaken away.
bunPluginLive

plugin(bunPluginLive({}))

b. Macro

import {getFileInfo} from '@live/mirror' with {type: 'macro'}

const filePath = import.meta.path // NOTE: This is segfaulting as of 20230722Sat
await getFileInfo(filePath)

Notes

We use this in Bun as a macro. Would also work at runtime too. But not in browser!

For Reflection duh!!!

Utils to read stuff from the current file's AST.
