[question] how do i get the path to the exported or installed package in cache?

Hi,

I would like to know the path in the cache to the package folder of a given package name and id.

For example:

/home/someuser/.conan/data/my-package-name/0.2.1/user/channel/package/e106f0e3de7fc8e9a057009394741ef4441857ec/

I tried with reconstructing the path but on windows, or with short/long path, it makes it hard to rebuild.

I would like a command or a python function to call that would take the package full name and the package id and it returns me the path to the package folder in cache.

It seems like ConanApi.get_path does the job but I don’t know how to call it from my script?

conan info does not return this information for a given package id, or I cannot get it work:

conan info my-package-name/0.2.1@user/channel:e106f0e3de7fc8e9a057009394741ef4441857ec

it does not work with package id

conan info --paths --package-filter my_package/1.0.0@mine/org --only “package_folder” C:\path\to\my\recipe\that\uses\this\package\conanfile.py

I fixed my use case by implementing the following function in my Conan wrapper :

import pathlib

from conans.client.conan_api import ConanAPIV1
from conans.client.tools.win import unix_path
from conans.model.ref import ConanFileReference
from conans.model.ref import PackageReference

def get_package_folder_in_cache(package_name: str, package_id: str) -> pathlib.Path:
    conan_api = ConanAPIV1()
    conan_api.create_app(quiet_output=False)
    ref = ConanFileReference.loads(package_name)
    package_layout = conan_api.app.cache.package_layout(ref, short_paths=None)

    pref = PackageReference(
        package_layout._ref, package_id  # pylint: disable=protected-access
    )
    pkg_folder = package_layout.package(  # pylint: disable=assignment-from-no-return
        pref
    )
    return pathlib.Path(unix_path(pkg_folder))

I know it is not elegant and may break at any time, but this is the only way I found to fetch the real package folder using the same layout mechanism that what conan actually use.
