Created command line tool

[phillipj]

Hey,

my first shot at a CLI used to render a mustache template with a data view and writes the template into stdout when successfull. Otherwise meaningfull errors into stderr.

The short story is it enables

$ mustache myTemplate.mustache dataView.json > output.html

Changes in the readme.md + tests pretty much sums it up.

Any thoughts?

I'd follow the ruby mustache argument order: mustache [data] [template]

(see mustache(1))

[bobthecow]

Also, we should allow users to specify - as the data or template argument, which would grab stdin.

cat data.json | mustache - myTemplate.mustache > out.html

Awesome! With @bobthecow's changes, I'd give 👍. Can't wait to have this, since I recently started toying with using package.json's scripts as my 'task-runner'.

[bobthecow]

While we're at it, how 'bout allowing an arbitrary number of datas? mustache <data> [<data> ...] <template>

[dasilvacontin]

@bobthecow, what would be the purpose of input? What's the expected output?

[bobthecow]

@dasilvacontin (Mustache.render(tpl, data) for data in datas).join("\n")

[dasilvacontin]

I see, interesting! Thumbs up incoming after the commits. :)

[phillipj]

Great feedback guys, thanks! I'll do some changes within the next couple of days :)

[phillipj]

Has changed argument ordering and added support for stdin.

@bobthecow multiple data views are interesting! Have you thought of scenarios where multiple data views would enable something one data view with an array as root could not?

E.g two views of:

{
    "message": "LeBron"
}

{
    "message": "r0x!"
}

compared to one view with:

[
    {
        "message": "LeBron"
    },
    {
        "message": "r0x!"
    }
]

I was thinking of a use case of a directory full of data files, and not having to preprocess them into a JSON array before using them. mustache messages/*.json message.mustache > messages.html

But I suppose you'd usually want to do more than newline delimited, so you're back to preprocessing.

[phillipj]

Played with that thought for a couple of minutes. Looks like it would be possible to push multiple single JSON objects into stdin reading them with the awesome JSONStream module.

$ cat messages/*.json | mustache - message.mustache > messages.html

Knowing its possible is good and all, but it doesnt really sound like you need it atm? If not lets do a PR on it later if/when someone actually needs it, I would happily contribute.

[bobthecow]

Don't hold anything up for my hypothetical feature. :)

[bobthecow]

jsonstream is pretty cool. i've played with it a bit as well :)

[dasilvacontin]

Cool!
