If you try to launch minecraft 1.12.2 (and older I think) you will get this error:

Custom error type must be used in order to improve error messages.

• Create a custom error type using thiserror.
  • Create Result type alias
• Replace all anyhow::Result with the custom one
• Remove anyhow dependency

• Build command

Regex here (^[a-zA-Z0-9_]{3,16}$) does not support "illegal nicknames" such as F (https://namemc.com/profile/F.1)

It's been a long time since the release of this launcher. And looking at the code now I can say that it's terrible in some places. That's why I will try to rewrite the current code in order to improve readability and make it easier to understand.
In addition to this, I want to implement mods downloading and support for #9 and #10 which is by itself will be easier after code refactoring.

Implement async Lazy type over tokio::OnceCell

Right now dowloading proccess is so hard to scale. Mostly because everythig is located in the one place. And it's also hard to keep track of the current downloading stage. My suggersion is a new dowloading system.

It should be based on the Dowloadable trait which will give us several methods to start dowloading, keep track of the current stage and check it's status.

The next part is TDownloader which are stucts that implemets Dowloadable trait. And should dowload only one thig. For example LibraryDownloader will download only one library and nothing more.

In adittion to this there will be DownloadSet and DownloadQueue which are utilites that gives a nice way to combine TDownloaders. And they also must implement Dowloadable

• DownloadSet allows to execute a bunch of downloaders in parallel.
• DownloadQueue allows to execute several downloads in sequence. And since DownloadSet implements Dowloadable we can easily combine those together.

Tracking tasks:

• Dowloadable trait
• Implemention of Dowloadable trait for common components
• DownloadSet
• DownloadQueue

Support for multiple instances of the game
