Support dashed args #7497

hulkish · 2018-12-11T10:59:42Z

Summary

Test plan

Added tests & ran:

yarn build && yarn jest

hulkish · 2018-12-11T11:03:11Z

@SimenB I imagine docs will need to be updated to reflect support for dashed args?

SimenB · 2018-12-11T11:57:13Z

Can we either

explore if yargs has an option for "merge options" which merges { 'foo-bar': true, fooBar: true } into { fooBar: true }
just use https://github.com/sindresorhus/camelcase-keys on argv returned from yargs

I imagine docs will need to be updated to reflect support for dashed args?

Yeah, a note saying both ways of defining the options are supported would be nice 🙂

Mind updating the changelog as well?

@SimenB

explore if yargs has an option for "merge options" which merges { 'foo-bar': true, fooBar: true } into { fooBar: true }
Doesn't appear to be so: https://github.com/laggingreflex/yargs-parser/blob/db92d552ec8869445209fc6dd54ab51be73e8f5f/index.js#L97

SimenB · 2018-12-11T12:16:44Z

Merging on our side is fine, then 🙂 I assume the values have been normalized, so it's not a lossy transformation

hulkish · 2018-12-11T12:17:57Z

@SimenB

just use sindresorhus/camelcase-keys on argv returned from yargs

The problem i see with this - is that it will convert dashed to camel. Then, it will report as if you attempted the camelcased arg.

hulkish · 2018-12-11T12:18:41Z

@SimenB ok, updated docs & changelog

rickhanlonii · 2018-12-11T17:53:20Z

Is the change here that you could pass args as dashed instead of camel case? Is there a reason we shouldn't enforce the current camelCase style?

SimenB · 2018-12-11T18:04:33Z

Standard cli is dashes, not camel. Jest is the only cli I know of that does camelCase

hulkish · 2018-12-12T12:55:32Z

@SimenB @rickhanlonii I noticed this is failing the node@6 ci build. Should it be passing, in order to allow merge?

Btw, (unrelated to above): latest release 24.0.0-alpha.7 is fubar - missing build dirs in jest packages. Ex:

$ mkdir foo && cd foo && yarn init --yes
$ yarn add [email protected]
$ ls node_modules/jest-cli/
> bin/  node_modules/  LICENSE  README.md  package.json
$ cat node_modules/jest-cli/package.json | jq -r .main
> build/jest.js

SimenB · 2018-12-12T13:00:28Z

Node 6 has to pass, yes 🙂 However, the failure looked transient, so I restarted the whole build. 🤞

hulkish · 2018-12-12T13:37:02Z

@SimenB found out why it was failing: Error: You can only use --detectOpenHandles on Node 8 and newer. - which is from my test. So, easy fix by swapping it out with a diff dashed arg... this should be good to go now

Just to verify, the object passed around as globalObject after jest-config has done its thing has just the camelCase keys, right?

@SimenB

Just to verify, the object passed around as globalObject after jest-config has done its thing has just the camelCase keys, right?

Hmm so good question - because, this is already an issue in master + this pr. I'll include that fix here:


const buildArgv = (maybeArgv: ?Argv, project: ?Path) => {
  const rawArgv: Argv | string[] = maybeArgv || process.argv.slice(2);
  const argv: Argv = yargs(rawArgv)
    .usage(args.usage)
    .alias('help', 'h')
    .options(args.options)
    .epilogue(args.docs)
    .check(args.check).argv;

  validateCLIOptions(
    argv,
    Object.assign({}, args.options, {deprecationEntries}),
    Array.isArray(rawArgv)
      ? rawArgv.map(rawArgv => rawArgv.replace(/^--?/, ''))
      : Object.keys(rawArgv),
  );

  return argv;
};

aka...remove the dashed entries of argv on the return.

hulkish · 2018-12-13T13:16:13Z

@SimenB k, using camelcase, filtering returned argv result & added test for it

nvm, fixed
