First steps to Qt

Installation

Steps:

1. Head to Qt's download section: https://www.qt.io/download.
2. Scroll down and click Go open source.
3. Scroll down and click Download the Qt Online Installer.
4. Click Download. The file is around 22,400 KB.
5. Open the installer, and go through the sections one by one. Some (probably) important options include:
   • You need to register a free Qt account upon reaching the Welcome section.
   • Expect around gigabytes of files to be downloaded in total, so choose a custom installation location if needed in the Installation Folder section.
   • Important -- In Select Components section, you need to manually select the components to download. The default options are not enough.
     • In Qt --> Developer and Designer Tools, select a MinGW distribution. For instance, I selected MinGW 8.1.0 x64.
     • In Qt --> Qt (any verison), select the SAME MinGW distribution. For instance, I selected Qt 5.15.1 --> MinGW 8.1.0 x64
   • The rest are straightforward enough. Aggregating all the necessary tools to download, the total size should not reach 5 GB.
6. Now wait and do whatever you want, there'll be a lot of files downloaded.

git cheatsheet

Better way: GitHub Desktop

Who still uses git in CLI lmao, get GitHub Desktop and let it do all the work for you :D (Includes instant diff checker!)

Download the repo

If you need to clone (download) this repository from the GitHub server to your machine:

• Navigate to the folder in which you want the files in the repository to be stored.
• Execute git clone https://github.com/54D/PacSnake.git to clone via HTTPS.

Modifying the code

After you've made changes to the code on your machine and you want to upload your progress:

• Execute git add . to add every file to the staging area.
• Execute git commit -m <message> to commit all the staged files. Now, your local repository contains the changes.
• Execute git push to add all your local commits to the remote repository (GitHub repository).

In the rare case we are very very organized and wish to use branches:

• If the branch you want to switch to...
  • ...already exists: git switch <branch_name>
  • ...doesn't exist yet: git switch -c <new_branch_name>
• Most likely you don't want to bring your changes to the branch you're switching to.
  • So, be sure to execute git stash first if you don't want carryover changes. This stores all your changes in a stack and allows you to work with a directory that doesn't contain the changes you just made.
  • See the list of stashed changes with git stash list.
  • Apply the most recent stashed change to the branch you currently are in with git stash apply.

Sync your progress

Before you work on the project it's a good idea to make sure your local copy is up-to-date. Execute git pull and if you see merge conflicts good fucking luck lmao.

Alternatively if you just want to get the new changes without merging yet, git fetch is your friend.
