Description

What's more fun than rewriting an already existing program? The learning process, of course.

This silly discount-wget downloads a file from the internet through HTTP or HTTPS, just like wget but with less features (Before writing this readme, I didn't know that wget could download a file over FTP or download an entire website). At the moment, discount-wget doesn't follow redirects. discount-wget now follows redirect once. This repository is only meant for learning.

Dependencies

• libuv: takes care of async I/O and event loop
• libcurl: only to parse URL
• llhttp: parses HTTP response
• openssl: handles TLS

Build

1. You'll need a VSCode with the C/C++ extension.
2. You'll need to install libuv, libcurl and openssl.
3. Follow the build instruction in llhttp.
4. Launch Compile and run discount-wget from VSCode.

Example

Build and run discount-wget. Try to download a relatively big file, e.g. Pgadmin4, which is about 210MB.

./build/main -o pgadmin4.dmg https://ftp.postgresql.org/pub/pgadmin/pgadmin4/v8.1/macos/pgadmin4-8.1-x86_64.dmg
md5 pgadmin4.dmg

Output:

MD5 (pgadmin4.dmg) = 22c62e3b61db9d25b6d67af50f54aa81

Verify this by downloading the .dmg file through a browser:

md5 ~/Downloads/pgadmin4-8.1-x86_64.dmg

Output:

MD5 (Downloads/pgadmin4-8.1-x86_64.dmg) = 22c62e3b61db9d25b6d67af50f54aa81
