Issue following tutorial code

[jhned]

Hey there, thanks for making this, this will really help me out! I'm not familiar with Python, but I'm trying to follow along with the tutorial. So far, I downloaded the repo, ran python3 setup.py and then put this code into a file titled SoftwareSourceCode.py:

from schemaorg.main.parse import RecipeParser
from schemaorg.main import Schema

spec = Schema("SoftwareSourceCode")
recipe = RecipeParser("recipe.yml")
print(recipe.loaded)

from spython.main.parse import DockerRecipe
parser = DockerRecipe("Dockerfile")

spec.add_property('environment', parser.environ) # currently a list
spec.add_property('entrypoint', parser.entrypoint)
spec.add_property('description', 'A Dockerfile build recipe')

spec.add_property('name', "vanessa/sregistry")
spec.add_property('ContainerImage', parser.fromHeader)

recipe.validate(spec)

from schemaorg.templates.google import make_dataset
dataset = make_dataset(spec, "index.html")
print(dataset)

I ran python3 SoftwareSourceCode.py and got this output:

Any idea what I'm missing off the top of your head?

hey @jhned ! Sorry for the trouble here - it's entirely a version issue for Singularity Python - we refactored the recipe parser (and I need to update the tutorial here). Can you point me to where you are reading and I'll do this asap?

[vsoch]

okay, so the fix is very simple, just these two lines here:

from spython.main.parse.parsers import DockerParser
parser = DockerParser("Dockerfile").parse()

I just opened a pull request to update all the examples, #25, if you want to take a look! Give that a go, and when you've confirmed it's good, I'll merge.

[jhned]

Hey @vsoch, thanks for the reply! I was reading about it here: https://openschemas.github.io/schemaorg/. I'll try the update now.

[jhned]

Ok, now I'm getting this message:

ERROR Cannot find Dockerfile, is the path correct?

Was I supposed to download a Dockerfile as well as part of this?

[vsoch]

Oh, you'd need to have a Dockerfile in your present working directory to work with! If you want a complete, packaged example, see this repo -> https://github.com/openbases/extract-dockerfile I've provided a Dockerfile in each folder.

[vsoch]

That repo is currently linked in the examples README: https://github.com/openschemas/schemaorg/tree/master/examples

And the google example folder does have a Dockerfile: https://github.com/openschemas/schemaorg/tree/master/examples/google

I think I mostly never expected someone to copy paste into a script from the getting started page and have it associated with a folder in the repo, sorry about that! Hopefully I've provided enough examples and files in other places so it's not a hassle.

[jhned]

No worries! Thanks for the help!
