Send DDS Event Associated With A Specific Yazi Instance

by ADMIN 56 views

=====================================================

Problem Description

In this article, we will explore the problem of sending a DDS event associated with a specific Yazi instance. The issue arises when using the yazi.nvim plugin, which has a default key mapping for cycling buffers using the <tab> key. However, this key mapping can be overridden by defining a custom Yazi keymap using ya pub. The problem is that the event is not associated with a specific Yazi session, causing it to be executed in all open editors.

Solution Overview

To solve this problem, we need to modify the yazi command to accept a --client-id flag, which will allow us to associate the event with a specific Yazi instance. This will enable power users to define custom key mappings for each Yazi session, improving the user experience.

Current Implementation

The current implementation of the yazi command does not check the client ID when emitting events. This means that all events are global and can be received by any Yazi instance. To fix this, we need to modify the yazi command to accept a --client-id flag and use it to associate the event with a specific Yazi instance.

Proposed Solution

Here is a proposed solution to the problem:

  1. Modify the yazi command to accept a --client-id flag.
  2. Use the --client-id flag to associate the event with a specific Yazi instance.
  3. Update the yazi.nvim plugin to use the --client-id flag when emitting events.

Code Changes

To implement the proposed solution, we need to make the following code changes:

// yazi-cli/src/main.rs
use std::env;

fn main() {
    // ...
    let client_id = env::var("YAZI_CLIENT_ID").unwrap_or_else(|_| "default".to_string());
    // ...
    ya.emit_to(client_id, "reveal", args);
    // ...
}

// yazi.nvim/plugin/yazi.nvim
use std::env;

fn emit_event(client_id: &str, event: &str, args: Vec<String>) {
    // ...
    let command = format!("ya emit-to {} {} {}", client_id, event, args.join(" "));
    // ...
}

Benefits

The proposed solution has several benefits:

  • It allows power users to define custom key mappings for each Yazi session.
  • It improves the user experience by enabling users to associate events with specific Yazi instances.
  • It is a simple and easy-to-implement solution that does not require significant changes to the existing codebase.

Conclusion

In conclusion, the proposed solution is a simple and effective way to send DDS events associated with a specific Yazi instance. By modifying the yazi command to accept a --client-id flag and using it to associate the event with a specific Yazi instance, we can improve the user experience and enable power users to define custom key mappings for each Yazi session.

Future Work

Future work on this project could include:

  • Implementing a more robust and secure way to associate events with specific Yazi instances.
  • Adding support for multiple client IDs and event types.
  • Integrating the yazi command with other tools and plugins to enable more complex workflows.

Q: What is the problem with the current implementation of the yazi command?

A: The current implementation of the yazi command does not check the client ID when emitting events. This means that all events are global and can be received by any Yazi instance.

Q: Why is this a problem?

A: This is a problem because it can cause events to be executed in multiple Yazi instances, which can lead to unexpected behavior and errors.

Q: How can we fix this problem?

A: We can fix this problem by modifying the yazi command to accept a --client-id flag and use it to associate the event with a specific Yazi instance.

Q: What is the --client-id flag?

A: The --client-id flag is a command-line flag that allows you to specify the client ID of the Yazi instance that should receive the event.

Q: How do I use the --client-id flag?

A: You can use the --client-id flag by adding it to the yazi command, followed by the client ID of the Yazi instance that should receive the event. For example:

yazi --client-id my-client-id emit-to reveal

Q: What happens if I don't specify a client ID?

A: If you don't specify a client ID, the event will be sent to all Yazi instances that are currently running.

Q: Can I specify multiple client IDs?

A: Yes, you can specify multiple client IDs by separating them with commas. For example:

yazi --client-id my-client-id-1,my-client-id-2 emit-to reveal

Q: How do I know what client ID to use?

A: You can find the client ID of a Yazi instance by running the yazi --debug command. This will display a list of all Yazi instances that are currently running, along with their client IDs.

Q: Can I use the --client-id flag with other commands?

A: Yes, you can use the --client-id flag with other commands that emit events, such as ya emit-to and ya pub.

Q: What are the benefits of using the --client-id flag?

A: The benefits of using the --client-id flag include:

  • Improved security: By specifying a client ID, you can ensure that events are only received by the intended Yazi instance.
  • Reduced errors: By specifying a client ID, you can avoid errors that can occur when events are received by multiple Yazi instances.
  • Improved flexibility: By specifying a client ID, you can customize the behavior of your Yazi instances to meet your specific needs.

Q: How do I implement the --client-id flag in my code?

A: To implement the --client-id flag in your code, you can use the following code:

// yazi-cli/src/main.rs
use std::env;

fn main() {
    // ...
    let client_id = env::var("YAZI_CLIENT_ID").unwrap_or_else(|_| "default".to_string());
    // ...
    ya.emit_to(client_id, "reveal", args);
    // ...
}

Q: What are the next steps?

A: The next steps are to implement the --client-id flag in all commands that emit events, and to test the new behavior to ensure that it works as expected.
