base library for oclif CLIs
If you're migrating from the old oclif libraries (@oclif/config, @oclif/command, @oclif/error, @oclif/parser), see the migration guide.
Without the generator, you can create a simple CLI like this:
TypeScript
#!/usr/bin/env ts-node
import * as fs from 'fs'
import {Command, flags} from '@oclif/core'
class LS extends Command {
static flags = {
version: flags.version(),
help: flags.help(),
// run with --dir= or -d=
dir: flags.string({
char: 'd',
default: process.cwd(),
}),
}
async run() {
const {flags} = this.parse(LS)
let files = fs.readdirSync(flags.dir)
for (let f of files) {
this.log(f)
}
}
}
LS.run()
.catch(require('@oclif/core/handle'))Then run either of these with:
$ ./myscript
...files in current dir...
$ ./myscript --dir foobar
...files in ./foobar...
$ ./myscript --version
myscript/0.0.0 darwin-x64 node-v9.5.0
$ ./myscript --help
USAGE
$ @oclif/core
OPTIONS
-d, --dir=dir [default: /Users/jdickey/src/github.com/oclif/core]
--help show CLI help
--version show CLI versionSee the generator for all the options you can pass to the command.
