base library for oclif CLIs
See the migration guide for an overview of breaking changes that occurred between v1 and v2.
The ux README contains detailed usage examples of using the ux export.
We strongly encourage you generate an oclif CLI using the oclif cli. The generator will generate an npm package with @oclif/core as a dependency.
You can, however, use @oclif/core in a standalone script like this:
#!/usr/bin/env ts-node
import * as fs from 'fs'
import {Command, Flags} from '@oclif/core'
class LS extends Command {
static description = 'List the files in a directory.'
static flags = {
version: Flags.version(),
help: Flags.help(),
dir: Flags.string({
char: 'd',
default: process.cwd(),
}),
}
async run() {
const {flags} = await this.parse(LS)
const files = fs.readdirSync(flags.dir)
for (const f of files) {
this.log(f)
}
}
}
LS.run().then(() => {
require('@oclif/core/flush')
}, () => {
require('@oclif/core/handle')
})Then run it like this:
$ ts-node myscript.ts
...files in current dir...
