Client for implementations of the [Global Alliance for Genomics and
Health (GA4GH)][res-ga4gh] [Tool Registry Service API][res-ga4gh-trs] schema,
including support for additional endpoints defined in [ELIXIR Cloud &
AAI's][res-elixir-cloud] generic [TRS-Filer][res-elixir-cloud-trs-filer] TRS
implementation.

## Usage

To use the client import it as follows in your Python code after
[installation](#Installation):

```py
from trs_cli import TRSClient
```

### Configure client class

It is possible to configure the `TRSClient` class with the `.config()` class
method. Currently there is only a single configuration parameter available,
the `debug` flag. Setting it to `True` (default: False) will have the exception
handler print tracebacks for every exception encountered.

Example:

```py
from trs_cli import TRSClient

TRSClient.config(debug=True)
```

> Note that as a _class method_, the `.config()` method will affect _all_
> client instances.

### Create client instance

#### Via TRS hostname

A client instance can be created by specifying the domain name of a TRS
instance, including the URL schema:

```py
from trs_cli import TRSClient

client = TRSClient(uri="https://my-trs.app")
# Client instantiated for URL: https://my-trs.app:443/ga4gh/trs/v2
```

Fully [spec-compliant][res-ga4gh-trs] TRS implementations will always be
available at `https` URLs, served at port `443` and at the base path
`ga4gh/trs/v2`. However, to allow the client to be used against development
versions of TRS implementations, `http` URLs are supported as well (default
port `80`), and the port and base path at which the API endpoints are served
can be overridden with the `port` and `base_path` arguments:

```py
from trs_cli import TRSClient

client = TRSClient(
    uri="http://my-trs.app",
    port=8080,
    base_path="my/api/route",
)
# Client instantiated for URL: http://my-trs.app:8080/my/api/route
```

#### Via TRS URI

Clients can also be created by passing a [hostname-based TRS
URI][res-ga4gh-trs-uri]:

```py
from trs_cli import TRSClient

client = TRSClient(uri="trs://my-trs.app/SOME_TOOL")
# Client instantiated for URL: https://my-trs.app:443/ga4gh/trs/v1
```

> **NOTE:** Only the hostname part of the TRS URI is evaluated, not the tool
> ID.

Port and base path can be overridden as described above. In addition, the
client constructor also defines the `use_http` flag, which instantiates a
client for an `http` URL when a TRS URI is passed. The flag has no effect
when a TRS hostname URL is provided instead of a TRS URI:

```py
from trs_cli import TRSClient

client = TRSClient(
    uri="trs://my-trs.app/SOME_TOOL",
    use_http=True,
)
# Client instantiated for URL: http://my-trs.app:443/ga4gh/trs/v1
```

### Access methods

> **NOTES:**
>  
> * All endpoint access methods require a [client
>   instance](#create-client-instance).
> * For accessing endpoints that require authorization, see the
>   [dedicated section](#authorization).
> * Responses that do not return the tool ID as a single string return
>   [Pydantic][res-pydantic] models instead. If dictionaries are preferred
>   instead, they can be obtained with `response.dict()`. See the [Pydantic
>   export documentation][res-pydantic-docs-export] for further details.
> * See the [API documentation][docs-api] for further details on each access
>   method.

#### Endpoints as specified in the TRS API

Access methods for each [Tool Registry Service API][res-ga4gh-trs] endpoint
are available:

| Method | Endpoint | Description |
| --- | --- | --- |
| [`.get_tool_classes()`][docs-api-get_tool_classes] | `GET ​/toolClasses` | List all tool types |
| [`.get_tools()`][docs-api-get_tools] | `GET ​/tools` | List all tools |
| [`.get_tool()`][docs-api-get_tool] | `GET ​/tools​/{id}` | List one specific tool, acts as an anchor for self references |
| [`.get_versions()`][docs-api-get_versions] | `GET ​/tools​/{id}​/versions` | List versions of a tool |
| [`.get_version()`][docs-api-get_version] | `GET ​/tools​/{id}​/versions​/{version_id}` | List one specific tool version, acts as an anchor for self references |
| [`.get_containerfiles()`][docs-api-get_containerfiles] | `GET ​/tools​/{id}​/versions​/{version_id}​/containerfile` | Get the container specification(s) for the specified image. |
| [`.get_descriptor()`][docs-api-get_descriptor] | `GET ​/tools​/{id}​/versions​/{version_id}​/{type}​/descriptor` | Get the tool descriptor for the specified tool |
| [`.get_descriptor_by_path()`][docs-api-get_descriptor_by_path] | `GET ​/tools​/{id}​/versions​/{version_id}​/{type}​/descriptor​/{relative_path}` | Get additional tool descriptor files relative to the main file |
| [`.get_files()`][docs-api-get_files] | `GET ​/tools​/{id}​/versions​/{version_id}​/{type}​/files` | Get a list of objects that contain the relative path and file type |
| [`.get_tests()`][docs-api-get_tests] | `GET ​/tools​/{id}​/versions​/{version_id}​/{type}​/tests` | Get a list of test JSONs |
| [`.get_service_info()`][docs-api-get_service_info] | `GET ​/service-info` | Show information about this service. It is assumed that removing this endpoint from a URL will result in a valid URL to query against |

#### TRS-Filer-specific endpoints

In addition to TRS API endpoints, the `TRSClient` class also provides access
methods for additional endpoints implemented in
[TRS-Filer][res-elixir-cloud-trs-filer]:

| Method | Endpoint | Description |
| --- | --- | --- |
| [`.post_tool_class()`][docs-api-post_tool_class] | `POST ​/toolClasses` | Create a tool class |
| [`.put_tool_class()`][docs-api-put_tool_class] | `PUT ​/toolClasses​/{id}` | Create or update a tool class |
| [`.delete_tool_class()`][docs-api-delete_tool_class] | `DELETE ​/toolClasses​/{id}` | Delete a tool class |
| [`.post_tool()`][docs-api-post_tool] | `POST ​/tools` | Add a tool |
| [`.put_tool()`][docs-api-put_tool] | `PUT ​/tools​/{id}` | Add or update a tool |
| [`.delete_tool()`][docs-api-delete_tool] | `DELETE ​/tools​/{id}` | Delete a tool |
| [`.post_version()`][docs-api-post_version] | `POST ​/tools​/{id}​/versions` | Add a tool version |
| [`.put_version()`][docs-api-put_version] | `PUT ​/tools​/{id}​/versions​/{version_id}` | Add or update a tool version |
| [`.delete_version()`][docs-api-delete_version] | `DELETE ​/tools​/{id}​/versions​/{version_id}` | Delete a tool version |
| [`.post_service_info()`][docs-api-post_service_info] | `POST ​/service-info` | Register service info |

#### Convenience methods

Finally, TRS-cli tries to provide convenience methods for common operations
that involve multiple API calls.  Currently there is one such method defined:

| Method | Description |
| --- | --- |
| [`.retrieve_files()`][docs-api-retrieve_files] | Retrieve all files associated with a given tool version and descriptor type. Useful for downloading workflows. |

### Authorization

Authorization [bearer tokens][res-bearer-token] can be provided either during
client instantiation or when calling an endpoint access method. The bearer
token is sent along as an `Authorization` header with every request sent from
the instantiated client instance.

> **NOTE:** Whenever a token is specified when calling an API endpoint, the
> `token` variable of that particular client instance is overridden. Thus,
> subsequent calls from that client will all carry the new token value, unless
> overridden again.

The following example illustrates this behavior:

```py
from trs_cli import TRSClient

# No token passed during client instantiation
client = TRSClient(uri="https://my-trs.app")
# Value of client.token: None

# Token passed during client instantiation
client_2 = TRSClient(
    uri="https://my-trs.app",
    token="MyT0k3n",
)
# Value of client_2.token: MyT0k3n
```

## API documentation

Automatically built [API documentation][docs-api] is available.
