Go zip updater: Appending new files to zip archive without decompressing the whole file
an invention by StarryWang
Updated over 1 year ago. 1 hackers ♥️. 1 follower.

Project Description

Currently, Golang's archive/zip standard library does not support appending new files to the existing zip archive.

Therefore, creating a simple zip archive library based on the Go zip standard library to add some Updater related method to allow appending new files to the existing zip archive without rewriting the whole file.

(Only for hacking and learning, and the final result of this project may not be stable to use in production.)

This modified zip library is used in my other HackWeek project Hangar. I will continue maintaining the Hangar and zip projects after HackWeek.

Looking for hackers with the skills:

    OpenQA Golang api client by hilchev

    Description

    I would like to make a simple cli tool to communicate with the OpenQA API

    Goals

    • OpenQA has a ton of information that is hard to get via the UI. A tool like this would make my life easier :)

    file-organizer: A CLI Tool for Efficient File Management by okhatavkar

    Description

    Create a Go-based CLI tool that helps organize files in a specified folder by sorting them into subdirectories based on defined criteria, such as file type or creation date. Users will pass a folder path as an argument, and the tool will process and organize the files within it.

    Goals

    • Develop Go skills by building a practical command-line application.
    • Learn to manage and manipulate files and directories in Go using standard libraries.
    • Create a tool that simplifies file management, making it easier to organize and maintain directories.

    Resources

    • Go Standard Libraries: Utilize os, filepath, and time for file operations.
    • CLI Development: Use flag for basic argument parsing or consider cobra for enhanced functionality.
    • Go Learning Material: Go by Example and The Go Programming Language Documentation.

    Features

    • File Type Sorting: Automatically move files into subdirectories based on their extensions (e.g., documents, images, videos).
    • Date-Based Organization: Add an option to organize files by creation date into year/month folders.
    • User-Friendly CLI: Build intuitive commands and clear outputs for ease of use. This version maintains the core idea of organizing files efficiently while focusing on Go development and practical file management.

    Hack on rich terminal user interfaces by amanzini

    Description

    TUIs (Textual User Interface) are a big classic of our daily workflow. Many linux users 'live' in the terminal and modern implementations have a lot to offer : unicode fonts, 24 bit colors etc.

    Goals

    • Explore the current available solution on modern languages and implement a PoC , for example a small maze generator, porting of a classic game or just display the HackWeek cute logo.
    • Practice some Go / Rust coding and programming patterns
    • Fiddle around, hack, learn, have fun
    • keep a development diary, practice on project documentation

    Jenny Static Site Generator by adam.pickering

    Description

    For my personal site I have been using hugo. It works, but I am not satisfied: every time I want to make a change (which is infrequently) I have to read through the documentation again to understand how hugo works. I don't find the documentation easy to use, and the structure of the repository that hugo requires is unintuitive/more complex than what I need. So, I have decided to write my own simple static site generator in Go. It is named Jenny, after my wife.

    Goals

    • Pages can be written in markdown (which is automatically converted to HTML), but other file types are also allowed
    • Easy to understand and use
      • Intuitive, simple design
      • Clear documentation
      • Hot reloading
      • Binaries provided for download
    • Future maintenance is easy
      • Automated releases
