find file location sent as a non-compressed artifact

Question

I have a python greengrass component that in itself is in a compressed artifact. I also have a non-compressed artifact in test/route.nmea that i want to access from within the python component.

```
 "Artifacts": [
        {
          "URI": "s3://jeteye/components/artifacts/au.com.company.gg_gps_publish/0.0.123/gg_gps_publish.zip",
          "Unarchive": "ZIP"
        },
        {
          "URI": "s3://jeteye/components/artifacts/au.com.company.gg_gps_publish/0.0.123/test/route.nmea",
          "Unarchive": "NONE"
        }
```

i tried:
`g_nmea_file = os.path.dirname(os.path.abspath(__file__)) + '/../test/route.nmea'
`
but that ends up pointing to the decompressed artifact directory :

`/greengrass/v2/packages/artifacts-unarchived/au.com.company.gg_gps_publish/0.0.123/gg_gps_publish/test/route.nmea`

is there a greengrass call to get access the non-unarchived artifact directory like:

`/greengrass/v2/packages/artifacts/au.com.company.gg_gps_publish/0.0.123/gg_gps_publish/`

?

I have also tried to pass in the **{artifacts:path}** variable that is available in the receipe by adding it to a config:

```
 "ComponentConfiguration": {
    "DefaultConfiguration": {
      "GGV2ComponentConfig": {
        "current_version" : "0.0.123",
        "gps_tick_topic" : "gps/tick",
        "timeout_sec" : 10,
        "test_nmea_file" : "{artifacts:path}/test/route.nmea"
      },
```

and passing it into the python like:

```
  "Lifecycle": {
        "Install": "pip3 install awsiotsdk pynmeagps",
        "Run": {
          "Script": "python3 -u {artifacts:decompressedPath}/gg_gps_publish/main.py '{configuration:/GGV2ComponentConfig}'",
          "RequiresPrivilege": "false"
        }
      },
```

when i read the GGV2ComponentConfig.test_nmea_file configuration , the **{artifacts:path}** part is empty

Hello,

`{artifacts:path}` would be the proper way to find the artifact location. You cannot use that string interpolation in the configuration however. Instead, you may pass it into your component using the command line or environment variables, for example in your recipe

```
lifecycle:
  run:
    script: python3 -u run_abc.py
    setEnv:
      ARTIFACT_PATH: "{artifacts:path}"
```
