Show jsonnet after concat/merge but before evaluation?

[strowi]

Hi,

i am currently trying to automatically produce some documentation from a tanka environment. I have all my variables under $._config.{a,b,c}, but (defaults) distributed over multible lib/{a,b,c}/secrets.jsonnet files.

First try i came up with:

• create separate file docs.jsonnet:

(import 'main.jsonnet') +
{
  docs: $._config,
}

And then parse that with some python script, but i am wondering if there is a better way? E.g. if tanka can show only the _config part or similar?

for completeness sake if someone stumbles over the same problem:

With the above i was able to write some python code that will load the json-data from tk eval environment/xyz/docs.jsonnet and use that to template some markdown file with jinja:

#!/bin/env python

import subprocess
import _jsonnet
import json
from jinja2 import Template

# 3. Formulate the command to evaluate the given Jsonnet file (tk is used for executing it)
command = "tk eval environments/xyz/docs.jsonnet"

# 4. Run the shell command and capture the output
result = subprocess.check_output(command, shell=True, text=True)

# 5. Convert the JSON output from the command into a Python dictionary
json_data = json.loads(result)

# 6. Load the Markdown template (Accounts.md.j2) using Jinja2 for further rendering
with open('docs/template.md.j2', 'r') as file:
    markdown_template = file.read()

# 7. Use Jinja2 to render the template with the data from the JSON dictionary
template = Template(markdown_template)
rendered_markdown = template.render(json_data)

# 8. Save the rendered Markdown content to a new file in the specified environment path
output_path = f'{args.environment_path}/readme.md'
with open(output_path, 'w') as file:
    file.write(rendered_markdown)

# 9. Inform the user that the file has been generated successfully
print(f"{output_path} has been generated with templated values.")

where

{
  docs: {
    a: 1
  }

would be referenced in the template as {{ docs.a }} etc.. see jinja docs for reference.
