A command line app that downloads all comics from xkcd.com and allows you to browse through them from the terminal.

Note: This project is no longer being updated or maintained. This was an early project of mine that helped me learn Go and concurrent programming. I'm leaving it up as an example of my early work for my code portfolio. The xkcd executable still works, but I no longer intend to add any new features.

Installing the xkcd binary

• Install the Go programming language on your machine, if you haven't already. Follow instructions here to do so.
  • Note that there are other methods for installing Go besides downloading and extracting the tarball (the method outlined on the official Go website). I won't detail them here, but as long as go version outputs something like go version 1.14.1 linux/amd64, you're fine.
• Install feh
  • sudo apt install feh for Debian-based distros
  • sudo pacman -S feh for Arch-based distros
  • ...or the equivalent for your distribution's package manager.
• run git clone github.com/scbrickley/xkcd from $HOME/go/src, if you're still using GOPATH, or from whatever directory you want if you have switched over to Go Modules.
• cd xkcd/cmd/xkcd
• go install

Usage

After installation, you should be able to type xkcd into your terminal to start the process. Initial download of all the comics may take a few minutes. Once it's done, a feh window should pop up and let you browse through the comics as you like.
