Especially, I'm struggling to have the demandOption helper displaying

hi guys do you know how can i get parsed argv inside .fail method?

Nicholas H.

@ukaaa

Is there a way to parse argv and turn them into an array of options in the shape of argv._?
So when I have

// argv
{
  _: [],
  foo: 'bar'
}

Turn it into

// parsed
['--foo', 'bar']

I would like to do this to get specific options out of the arguments, but pass the remaining ones to a child process using cross-spawn

hey gusy, I ran npm uninstall yargs --save-dev and npm uninstall yargs but still see yargs in node_modules folder? My npm is version 5.6.0.

is it possible to specify default command with variadic list of arguments?

I'm trying various forms of array, type: array etc but cant make it work

i'd like my script to be usable as

my_script input input2 input3 --other option

Mateusz Burzyński

@Andarist

found it in tests :see_no_evil:

$0 [input..] does the trick

I am fairly new to Yargs but wanted to know if it was possible to prefix commands with global arguments. So when running the command it would apply to any and all commands

script-name global-arg command --option=1

Hello, I have a question regarding sub-commands. I would like to have a command called remote with two sub-commans - add and rm. Each of these sub-commands will require one or more values. I'm struggling to achieve that. The closes I found was "positionals", but I can't figure out how to say that there should be at least one "positional" specified and how to say for which positional the number of required values. How is this supposed to be done with yargs? Here is what I have so far:

const yargs = require('yargs');

yargs.command(
  'remote',
  'Manage a remote,
  (yargs) => {
    yargs.positional('add', {
      describe: 'Adds a remote',
      type: 'string'
    });

    yargs.positional('rm', {
      describe: 'Remove a remote',
      type: 'string'
    })
  }).argv

How can I specify that add and rm subcommands should expect some number of arguments?

how can I tell yargs that at least add or rm should be specified?

is there somewhere an example?

@ljharb

demandOption?

or required: true probably

Iliyan Peychev

@ipeychev

but I want only one to be required at time, not both

either add or rm

Jordan Harband

@ljharb

i think you want to then have two commands - remote add and remote rm

and then .demandCommand

Iliyan Peychev

@ipeychev

hm, so to create two commans, called remote add and remote rm? Doesn't yargs support kinda sub-commands?

I thought "positionals" are the closest one to this concept

Jordan Harband

@ljharb

i'm not sure how to require only one of those two tho, as subcommands

Iliyan Peychev

@ipeychev

hm, I can't believe this is not possible with yargs. A good example would be git remote --help - there are many sub-commands plus additional params for each of them

this is what I want to achieve

like:

git remote rename <old> <new>
git remote remove <name>

Jordan Harband

@ljharb

i mean that is in the examples

Iliyan Peychev

@ipeychev

interesting, I'll check this. this thing with merging separate files I'm not sure I like very much on first sight (I hate magic), but I'll try to see of I'll build something based on that

thanks!

Hi guys,

I have a problem no other command line parsing library I've explored (probably) supports and since the generality of yargs, maybe you have some solution for it, but I can't really tell as from many options you provide, I'm a bit lost :).

I want to get a list of possibly multiple commands with arguments in a row as defined on the command line, so that I can build from it a "functional pipeline", that will be applied to some array/iterator/stream.

Is this case somehow solvable with yargs?

Many thanks...

@faraazahmad

what does the nargs() function do?

I looked at the docs, and I dont understand it

an example or 2 would be really helplful

Had a quick question. I am building a CLI using yargs and want to give users the options to add their own commands in a specific folder. I know I can use the following to accomplish this:

.commandDir(path.join(process.cwd(), 'commands))

This works great when the folder exists in the project, but if it does exist I get the following error:

Error: Error: ENOENT: no such file or directory, scandir 'DIRECTORY_PATH'

is there a way add the command directory ONLY if the directory exists?

Joel Kirchartz

@JKirchartz

hey, I'm trying to use commandDir here in /bin to load commands from /lib but it seems the positional arguments only work for the first command and not the other ones? am I doing something wrong? https://github.com/jkirchartz/pos2tracery

Hi, I'm having trouble writing typescript yargs unit tests. Can anyone help with this issue: https://stackoverflow.com/questions/60038269/how-to-correctly-unit-test-yargs-in-typescript,
thanks.

Hi, I am wondering whether yargs supports command lines as the following: myprog -r repo -v clone -p proj -a, i.e. having arguments (-r, -v) that are available for each command and are specified before it and arguments that are only valid for a specific command (-p, -a). Similar to https://git-scm.com/docs/git. I tried using something like yargs.option(...).command(...) but that did not seem to work.

Leroy van Engelen

@lvanengelen

To clarify: In the example clone is a command, not an argument to -v. Only now seeing how unclear that was sigh

Hey all. Is there a known working recipe for nested completions? Suppose I have cmd a [a1, a2,a3]. When I punch in subsequently cmd a a1 I continue to get completions as a1 a2 a3 even if I did a .completion(a1, ...) with higher specificity options

Hey folks, if writing CLIs with yargs, is there a recommended way to do any sort of logging? Is it just a matter of use npm/debug, or npm/winston?

Is it just me, or is http://yargs.js.org/docs/ missing its content?

https://raw.githubusercontent.com/yargs/yargs/v15.4.1/docs/api.md returns 404 for me
