jexer VS Guice

Very interesting! I was thinking literally yesterday about a TUI/GUI Qubes type concept, maybe also applicable for industrial type data diodes.

I did something like that once. Is your project online somewhere? I'm always curious what else is going on. :)

When I transliterated from D to Java around 2015, Java wasn't quite the "uninteresting" language it is perceived to be today. But all along I had hoped others might pick up some tricks, and put some notes on porting it here. Yet Java's been a pretty solid workhorse for me, and having the Swing GUI to test on was a godsend actually once I got into images.

If you code in Java, and like TUI (console type applications), then you might enjoy Jexer: https://gitlab.com/klamonte/jexer

I started Jexer in 2013, and off-and-on it's gotten better. I think my favorite part has been crossing paths with other terminal emulator ecosystem folks over the last few years. This release brings a few prettified effects inspired by other projects that you are all hopefully quite familiar with (notcurses, chafa, and vtm):

* Translucent windows, including images under/over each other and text.

* Animated/pulsing text

* Animated gifs

* A new XtermVideoPlayer example that uses ffmpeg/JavaCV to play movies inside a text-draggable window. (No audio though.)

* New button styles: round, diamond, left/right arrows. The button ends and shadows are drawn with images so specific font support is not required.

* A _much_ faster and _much_ higher quality sixel encoder.

* Different window border styles: single, double, none, and rounded corners.

* A femme theme option.

Some screenshots are posted here: https://twitter.com/AutumnMeowMeow/status/148922891703050240...

It's on maven and Sourceforge.

If you code in Java, and like TUI (console type applications), and enjoy transfemme in-jokes, then you might also enjoy jexer.

A path that started in the BBS era and is currently bringing DOOM to Xterm. And ironically, there is much better support for this now than there ever was for RIPscript.

Story time: when I first posted Jexer to Reddit, people were all "twin does that". No, it does not. twin does not pass vttest. twin has almost no widgets. twin does not support images at all, it does not multiplex images, it does not multihead images, and it does not play videos (a bit too slowly but still) in a text draggable/resizable window that could be part of a larger system. mpv/mplayer doesn't do those things either. In fact, the only two projects I know of that can do these kinds of tricks are Jexer and notcurses. (And notcurses is hella faster and great, and I would have used it in 2013 when I started Jexer, but it didn't exist then.)

One way to do translucent windows. - Inspired by notcurses

foot is great, dnkl is great. It's so far the fastest sixel-supporting terminal I've got to test XtermDOOM on. (I run iTerm2-based images against wezterm.)

It parses them, but then reduces to the 8/16 ANSI colors. Which makes translucent TUI windows not work. :(

Historically, Ports and Adapters was born in the context where Dependency Inversion Principle (DIP) was getting hot, back in the beginning of the 2000’s. DIP was getting more present on development day to day, and an example of a framework that was a pioneer in such topic is Google Guice.

“There are many advantages to using dependency injection, but doing so manually often leads to a large amount of boilerplate code to be written. Guice is a framework that makes it possible to write code that uses dependency injection without the hassle of writing much of that boilerplate code”

This is a common misconception. Guice’s docs delineate between dependency injection as a pattern and Guice as a framework that supports that pattern.

https://github.com/google/guice/wiki

You can (and it's very normal to) use that with new. Dependency injection frameworks (like guice) let you skip passing long parameter lists to constructor arguments like you mention. But you don't really NEED that. They also will solve circular dependency issues and some other things, although a strong argument could be made that you should simply restructure your code so that those issues don't exist.

Bob was a nice guy. We had an overlapping tenure at Google in the 2000s. He was one of the original authors of the Guice dependency injection framework: https://github.com/google/guice. When I was earning Java readability at Google, I was fortunate to have had him assigned as a reviewer. Huge loss; he left a very positive impression on me.

He was fairly well known figure in the Java world. RIP.

Usually each context has a different scope and lifetime associated with it. Here, it sounds like there are two distinct scopes: server and request (cf. how Guice models scopes: https://github.com/google/guice/wiki/Scopes). It is rarely sensible to merge the scopes or contexts together. If we think about a context, it contains several things:

using libraries from java world, such as Guice;

As said in the title, we will focus on the dependency inversion principle and one of its application : dependency injection. For production-ready applications, it would be better to rely on a framework and not implement its own container. For it, the java ecosystem have 3 frameworks available : Spring, Guice and Dagger.
