Introduction

This program allows you to download files like images and attachment automatically without you doing the hassle of downloading them yourself from supported platforms like Fantia, Pixiv, and more!

I did this project as I was tired of downloading images manually as some artists do not provide zip files...

Hence, I coded this program to automate the process of downloading images from a post via web scraping.

In the end, I spent about a month doing developing the initial program in Python while learning concepts such as web scraping, async, threading, and more.

After learning Go/Golang however, I decided to rewrite the program in Golang with a GUI using wails with Svelte as the frontend framework.

Running the Program

Running the .go files
- Clone this repository/Download all the files in this repository.
- Install the latest version of Go/Golang and Node.js
- Install the Wails CLI by running go install github.com/wailsapp/wails/v2/cmd/wails@latest
  - Refer to the Wails documentation if there is any issues faced when installing the Wails CLI.
- Run wails build in the root directory of this repository to build the binary and run the program.
  - Alternatively, you can run wails dev to run the program in development mode.
Running the executable file
- Download the latest Cultured Downloader archive/zip file which will contain the executable files from the releases page
  - Not sure what x86_64 or arm64 means? Those are the architectures of your system and x86_64 is the most common architecture for various systems.
    - Note: x86_64 is also known as x64 or amd64 in some systems.
  - Please check your system's architecture before downloading the zip file. For instance, Apple M1 Macs are using the arm64 architecture.
- Once downloaded, you can do an integrity check for security reasons by comparing the SHA256 hash of the downloaded zip file with the hash provided in the release notes.
  - For instance, _sha256checksum_windows_x86_64-628b21a1b0dbf33a1137432e0f350e5c4bd49ecac9fa2f8a261555433967d394 contains the SHA256 hash of the zip file that contains the executable file for Windows AMD64 systems.
    - The 64 characters 628b21a1b0dbf33a1137432e0f350e5c4bd49ecac9fa2f8a261555433967d394 suffix is the SHA256 hash of the executable file.
    - You can also simply open it as a text file which would contain the SHA256 checksum as well.
- Finally, extract the executable file from the archive/zip file and run it.
  - For Linux and macOS, if you're having difficulty extracting the .tar.gz archive file, you can use the terminal to extract the file using the tar -xvf <filename>.tar.gz command.

Does this work on other OS platforms such as macOS and Linux?
- This program has only been tested on Windows and Linux (Ubuntu). However, it should work on other Linux distros and macOS as well.
The program suddenly closes/crashes! What should I do?
- This is due to how error handling in Golang works, when a fatal error occurs, the program will panic and closes itself.
