[Feature Request] Implement a RPC Way Like Fzf's --listen

As a user of the skim command-line interface, I believe it would be beneficial to implement a Remote Procedure Call (RPC) interface similar to the one provided by fzf. This feature would enable developers to write clients in other languages to interact with skim using a standardized API. In this article, we will explore the benefits of implementing such a feature and discuss how it can be achieved.

What is RPC?

RPC is a communication protocol that allows a client to call methods on a server without having to know the details of the underlying implementation. This enables developers to write clients in different languages and interact with the server using a standardized API. RPC is commonly used in distributed systems, where multiple components need to communicate with each other.

Fzf's --listen Flag

fzf is a popular command-line interface for searching and filtering files. In version 0.36.0+, fzf introduced a --listen flag that enables users to write clients in other languages to interact with it using an HTTP API. This feature allows developers to create custom integrations with fzf using their preferred programming language.

Benefits of Implementing RPC in Skim

Implementing a RPC interface in skim would provide several benefits, including:

  • Increased flexibility: Developers would be able to write clients in different languages to interact with skim, making it easier to integrate with other tools and systems.
  • Improved customization: With a standardized API, developers would be able to create custom integrations with skim that meet their specific needs.
  • Enhanced collaboration: RPC would enable multiple developers to work together on a project, each contributing their own expertise and skills.

How to Implement RPC in Skim

To implement RPC in skim, we would need to follow these steps:

  1. Choose a RPC framework: We would need to select a RPC framework that supports the desired programming languages and protocols. Some popular RPC frameworks include gRPC, Thrift, and Apache Arrow.
  2. Design the API: We would need to design a standardized API that provides a clear and concise interface for interacting with skim. This would involve defining the methods, parameters, and return types for each API call.
  3. Implement the server: We would need to implement the server-side logic for handling RPC requests and sending responses back to the client.
  4. Test the implementation: We would need to thoroughly test the implementation to ensure that it works correctly and provides the desired functionality.

Example Use Case

Here is an example use case for implementing RPC in skim:

Suppose we want to create a custom integration with skim that allows us to search for files using a specific search query. We would need to write a client in our preferred programming language (e.g., Python) that sends an RPC request to the skim server with the search query as a parameter. The skim server would then process the request and send back a response containing the search results.

Code Example

Here is an example code snippet in Python that demonstrates how to send an RPC request to the skim server:

import grpc

# Define the RPC client
class SkimClient:
    def __init__(self, host, port):
        self.host = host
        self.port = port
        self.channel = grpc.insecure_channel(f"{host}:{port}")

    def search_files(self, query):
        # Send the RPC request
        request = SearchRequest(query=query)
        response = self.channel.unary_unary(
            "/skim/Search/SearchFiles",
            request,
        )
        return response

# Define the RPC request message
class SearchRequest:
    def __init__(self, query):
        self.query = query

# Define the RPC response message
class SearchResponse:
    def __init__(self, results):
        self.results = results

# Create a SkimClient instance
client = SkimClient("localhost", 50051)

# Send the RPC request
response = client.search_files("example query")

# Print the search results
print(response.results)

Implementing a RPC interface in skim would provide several benefits, including increased flexibility, improved customization, and enhanced collaboration. By following the steps outlined in this article, we can create a standardized API that allows developers to write clients in different languages to interact with skim. The example code snippet demonstrates how to send an RPC request to the skim server using the gRPC framework.

Q: What is RPC and why do we need it in Skim?

A: RPC stands for Remote Procedure Call, which is a communication protocol that allows a client to call methods on a server without having to know the details of the underlying implementation. In the context of Skim, RPC would enable developers to write clients in different languages to interact with Skim using a standardized API. This would increase flexibility, improve customization, and enhance collaboration.

Q: How does Fzf's --listen flag work?

A: Fzf's --listen flag enables users to write clients in other languages to interact with Fzf using an HTTP API. This allows developers to create custom integrations with Fzf using their preferred programming language. The --listen flag listens for incoming requests on a specified port and responds with the requested data.
