DEMSF-RS - Download and extract Microsoft Sharepoint file crafted using Rust

I've created this Rust utility program designed for SREs, DevOps, and Developers to download files from a Microsoft Sharepoint repository.
This project has undergone a rewrite from its original source at https://github.com/phlbrz/demsf, which originally utilized bash utility scripts. The process of transitioning to Rust was initiated with the assistance of ChatGPT.
These scripts are primarily intended for automation in CI pipelines or local setups (developer environment).
As the Sharepoint link I share is public and doesn't require authentication, the utility provides seamless access.
The current implementation utilizes some crates for downloading and Unzip for extraction, but if you prefer an alternative extractor, please don't hesitate to let me know by raising an issue.

Repository structure

```bash tree -I target demsf-rs/

demsf-rs/ ├── Cargo.toml # crate/libs from crates.io ├── LICENSE ├── README.md └── src ├── args.rs # a struct and impl mod to encapsulate args from input. ├── download.rs # Download a Microsoft Sharepoint File. ├── lib.rs # Declared mods. ├── main.rs # Execute the program. └── unzip.rs # Unzip a file downloaded from Microsoft Sharepoint. ```

Requirements

• Linux
• Rust

Usage

• Create your workspace

bash mkdir $HOME/workspace-rust/ cd $HOME/workspace-rust/

• Clone this repository

```bash git clone https://github.com/phlbrz/demsf-rs.git cd demsf-rs

OUTPUTFOLDER="/home/user/workspace/demsfoutput/" OUPUT_FILENAME="file-name.zip" URL="https://some-shared-repo.sharepoint.com/:u:/s/SharedRepo/XXXxXXxXxXxXxxXxXxxxxxxXXx1xxxx2X3X4XxxxXXxXXX?e=XXxxX1"

If you want to extract a zip

cargo run -- "$OUTPUTFOLDER" "$OUTPUTFILENAME" "$URL" true

If you don't need to extract a zip

cargo run -- "$OUTPUTFOLDER" "$OUTPUTFILENAME" "$URL" false ```

How to use the crate

• To download a file from Microsoft Sharepoint, unzip must set to false.
• To unzip a file from filesystem, unzip must set to true, or don't call download function.

```rust use log::{debug, error};

use demsfrs::args::Args; use demsfrs::download::download; use demsf_rs::unzip::unzip;

fn main() { envlogger::init(); match Args::parsearguments() { Err(why) => { error!("Error"); panic!("{:?}", why) } Ok(mut value) => { debug!("call download."); // if you don't want to download, comment this line. download(&mut value); // if you don't want to download, comment this line. debug!("call unzip? value={:#?}", &value.unzip); // if you want to unzip, set true match &value.unzip.parse() { Ok(true) => unzip(&value), Ok(false) => (), Err(_) => panic!("Only true or false is valid for unzip option."), } } } } ```

• Rust file download.rs: Download a Microsoft Sharepoint File

This script facilitates the retrieval of files from Microsoft Sharepoint.
It leverages the args.rs module, prepopulated with OUTPUT_FOLDER, OUTPUT_FILENAME, and URL.

• Rust file unzip.rs: Unzip a file downloaded from Microsoft Sharepoint

This will unzip the file.
It leverages the args.rs module, prepopulated with OUTPUT_FOLDER, OUTPUT_FILENAME, URL and you must set true calling the program in command line.
