Allow regex parsing of files

[koseduhemak]

Hi,

I got an idea for a new feature: Regex parsing which contents of a file should be extracted.
As files tend to change, it would be very helpful to enhance the parser to allow something like:
my-file.json#R:/"scripts".*\]/imgs
which should match the following contents of my-file.json:

... other content here...
"scripts": [
    "scripts/general-env-variables.sh",
    "scripts/ca-certificates.sh",
    "scripts/apt-install.sh",
    "scripts/timezone-fix.sh",
    "scripts/python-pip-repository.sh",
    "scripts/cloudfoundry-cli.sh",
]
... other content here...

See here for example: https://regex101.com/r/URfVWn/1

This way we can extract in a more flexible / reliable way and do not need to adjust start and end of line if source files are changing...

What do you think?

Best wishes,

So to clarify you're suggesting that an additional suffix be permitted that instead of defining which lines numbers to embed, it defines which lines matching an expression to embed?

I think this is a great idea, especially for data sources rather than code sources.
