Again, you can type feet instead of ft and it'll work. You can write 'feet per second' instead of 'ft/s' and it'll work. Natural language has its benefits but when you have a very simple syntax model then there's less chances of it making a mistake.

I also like it very much. I hope they make a library for it soon, I can't wait to use it to make unit aware calculators.

[-] thevoidzero@lemmy.world 2 points 1 day ago* (last edited 1 day ago)

I mean the syntax for gnu units is literally the same unit expression used in math. m^2, cm, m/s etc. the ft;in looks weird because it's two units combined.

Your example in it would be units 30ft mm , use -t for terse results that's just the final value.

Doesn't even work well on a single monitor on Wayland. It gets confused with screen size or sth, fills a small area on top left with screen contents and lot of black space

Hi all,

I don't know where would be the best place to post this, but I wanted some people's feedback on a DSL that I wrote for network analysis.

I am using nom for writing the lexer and parser, then using abi_stable crate for data types so that you can write plugins to the language and load them dynamically as well.

This language is made to work by loading a tree graph (network) and then call a bunch of node or network functions that work on it. There are different ways you can run functions, and use node/network attributes.

I am mostly self-taught, so it took a lot of years to get to a level where I could write something like this. I am learning a lot and having a lot of fun in the process, but I want this to develop into something that can have a practical usefulness to people. Since I am in the field of hydrology, I am making it with river networks in the mind.

To try it out, you can either download the executables for windows from the releases page, or you can compile it using cargo (for all OS; except android where GUI won't work, CLI will work in termux). I have some basic examples in the Learn By Examples section of the User Guide that you can follow.

Please let me know if you can't compile/use it as well. I have tried to make sure it has required instructions, but I could have missed something.

People knew. Then everything started being "i need people to work in my factory/office doing the same thing again and again" and everyone had to be the same.

Edit: Think of all the advancement in science from people that were not "normal", now they'd have just failed basic school and never had any chances to do academia. I think Einstein failed history and other subjects in a college entrance but excelled in physics and math.

Looking for Mentor (for a PhD Candidate) that works with open source and Rust

TLDR: Searching for person holding professor position to officially act as a committee member on a US PhD defense

Hi all,

I'm in a non CS field. I'm doing PhD in hydrology and I'm good at Geospatial Analysis, data analysis, visualization, modeling and such. I really like programming and have been making open source programs, contributing to open source programs and such. And have been learning rust for last 2 years.

For my PhD dissertation I'm doing a project where I'll be using Rust to make a program with compiled plugin system that can do generalized river related tasks including data analysis and visualization. I have professors in GIS and hydrology to guide those aspects, but I don't have anyone on software side to ask questions, or to look at my work. I tried emailing some people I have seen with open source projects on GIS+rust, but no response.

I'm ideally looking for someone that holds a professor position for my committee who is good with either rust, GIS related algorithms development, and programming languages. However, it woud also be helpful to just have someone woth knowledge about such things. In either scenario, credit and authorship will be given.

I appreciate any response even telling where i could find someone matching the above description. :)

Edit: I can also provide my previous projects in GitHub, websites and such before you decide in messages.

Then you start saying you can't complete things, ask them which one is the priority. And actually not do everything.

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 }
  }
}

Underscore to delineate different parts, hypen to delineate words.

Like: my-resume_draft.pdf

And to make it consistent and easier to reuse parts for project names and such, I have a command line utility written for it. It caches the parts and uses a template system (support for generating current datetime in parts)

Available here (is in AUR too):

TLDR: I recently found out there is "deprecated" XFA format that acrobat still uses in their programs, and government forms have those for dynamic contents in the form that we cannot fill using other softwares. Looking for solutions.


This has been a problem since a long time. Back in 2020 I had dual boot because I needed acrobat to fill PDF forms, but after finding xournal++ program I nuked windows partition. Windows update messing up grub was one of the reason I decided to nuke windows and looking at the posts recently it's still a huge issue.

So the problem I recently encountered is that even the government issued PDF forms need acrobat reader (which is free software for PDF, but only available in windows and mac). Which I didn't think would be an issue and just filled the form in Firefox.

Turns out that was problematic as the PDF forms has fields that are automatically filled, calculated from other fields, only made available when certain checkboxes are checked, etc. and Firefox doesn't support that. Even trying to install the acrobat reader snap (which uses wine) in a VM and opening the PDF on it didn't work. The UI makes me think it's a really old version of the reader.

So without searching for other devices (and filling a PDF with my sensitive information) what solution is there? Installing windows is a hassle even in a VM, and it will use up precious SSD memory. But that's the only solution I can think of.

I also found masterpdf or something like that which the Arch wiki says has support for that, but it didn't work. It says XFA forms are converted to acro forms, and the dynamic part doesn't work. There are websites that promise to work for such forms, but I'm not going to be putting sensitive info on web apps.

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.

You can use your library for commercial projects that you have. Just have dual license that requires payment for commercial use or something similar. You don't have to pay yourself
