No input argument received on validate

[loranger]

Hello,

Sorry to bother, but even if mjml is a wonderful project allowing us to make universal responsive emails, we still can break all the thing by typing errorneous tags. That's what I did few weeks ago, without noticing my emails were broken on production.

Once we did figure out there was a remaining trailing space in an mjml tag, I decided to add an mjml linter on my git commit hook

But I still can't make it work. I'm not sure what I did wrong, so here is what I did.
Can someone point me on what I did miss ?

Reproduction Steps:

1. I use mjml inside a laravel project.

Even if the validator is installed (as a dependency ?), I cannot use it until I install it explicitely :

$ ls -la node_modules

$ ls -la node_modules

$ mjml --validate

$ ./node_modules/.bin/mjml --validate resources/views/mjml/welcome.mjml
Too much input arguments received

$ mjml-cli --validate

$ ./node_modules/.bin/mjml-cli --validate resources/views/mjml/welcome.mjml
Too much input arguments received

2. So I install the mjml-validator explicitely

$ npm i mjml-validator --save-dev

Then the error message is slightly different

$ mjml --validate

$ ./node_modules/.bin/mjml --validate resources/views/mjml/welcome.mjml
No input argument received

$ mjml-cli --validate

$ ./node_modules/.bin/mjml-cli --validate resources/views/mjml/welcome.mjml
No input argument received

I took a deeper look at the documentation, but I stil can't find my error. Could you help, please ?

Expected behavior:

A validation output listing my markup errors

Observed behavior:

It looks like the mjml command does not understand the validate flag or the input file

MJML version:

• mjml-core: 4.0.1
• mjml-cli: 4.0.3

Hi @loranger !

I think --validate option hasn't been backported yet into the 4 cli yet, @kmcb777 can you take a look to add it back for 4.1 ? 👍

Hi @loranger we released a new beta for mjml 4.1, which you can install with npm install mjml@next, could you check if the --validate option is working as you wish ?
