Hi all.

I want to develop a plugin system within my program, and I have a trait that functions defined by plugins should implement.

Currently, my code gets all the functions in a HashMap and then calls them by their name. Problem is, I have to create that hashmap myself by inserting every function myself.

I would really appreciate it if there was a way to say, suppose, all pub members of mod functions:: that implement this trait PluginFunction call register(hashmap) function. So as I add more functions as mod in functions it'll be automatically added on compile.

Pseudocode:

Files:

src/
├── attrs.rs
├── functions
│   ├── attrs.rs
│   ├── export.rs
│   └── render.rs
├── functions.rs
├── lib.rs

Basically, in mod functions I want:

impl AllFunctions{
    pub fn new() -> Self {
       let mut functions_map = HashMap::new();[[
       register_all!(crate::functions::* implementing PluginFunction, &mut functions_map);
       Self { function_map }
  }
}

Right now I'm doing:

impl AllFunctions{
    pub fn new() -> Self {
       let mut functions_map = HashMap::new();[[
       crate::functions::attrs::PrintAttr{}.register(&mut functions_map);
       crate::functions::export::ExportCSV{}.register(&mut functions_map);
       crate::functions::render::RenderText{}.register(&mut functions_map);
       // More as I add more functions
       Self { function_map }
  }
}

Hi everyone,

I'm hoping there are people here who work on FOSS and have applied for grants to support their software financially. I am applying for a grant opportunity that is asking for a software from US gov agency.

My requirements:

• I want to publish it under Open Source Licenses like GPL (not MIT) so other corps can't take this to use on their product,
• The grant agency will get the source code, they can do whatever as long as the license is held,
• I will develop the features they want, and request during the duration of grant,
• I will want to continue development independently after the grant, or apply for more grants from other organizations,
• To clarify the previous point, I do not want to give them the final product so they own it, and I can no longer do anything on the program.

So, if anyone has done similar things, please give me advice on this. Their requirement says "a web repository" should be provided at the end, so I think I can apply with the intention of giving them the software code while keeping the rights. But I don't want to make a mistake in application/contract and lost the rights to the program, I want to develop a lot further than just the features they want for their use case.

Or at least dual license to protect the Open Source Side while giving the grant organization rights to take the code for their other programs because of the money they spent.

This feels like it should already be a feature in a terminal. But I didn't find anything that let me do this efficiently.

I had a rust library for converting list like 1-4,8-10 into vectors, but thought I'd expand it into a command line command as well, as it is really useful when I want to run batch commands in parallel using templates.

I wanted to share it since it might be a useful simple command for many people.

Hi all,

mpv communities seem to be tiny in lemmy, so I'm sharing it here.

This is a program I made for music control from local network.

You can run it in a computer with some local media files, or youtube links or any other links yt-dlp supports. And then with the server, you can control the media player and the playlist from any devices in your local network. So that you can just show a QR code or something to house guests for parties, or have it bookmarked within family to control the music.

I wanted to make something similar to how youtube app let's you play in TV and such, but my skills were not enough to do that. So I tried a simple alternative that works with computers. In an ideal world, I could make "Play with local mpv server" option come while on other android apps, but I have zero experience in android app development and it looks complicated.

I know some other programs also give option to control media, but I wanted to give it a go with a simple implementation. Making the web-server was a tricky part. Only tutorial from the rust book was useful here as every other web server developement in rust seems to be async ones using libraries so I would have to make a complicated system to communicate with the mpv. Using the simple Tcp connection let me make a thread with mpv instance in the scope. I do need to support https and file uploads and other things, but I haven't had any luck finding a solution that works with simple Tcp connection like in the tutorial. Let me know if you know anything.
