zsh-autocomplete
🤖 Real-time type-ahead completion for Zsh. Asynchronous find-as-you-type autocompletion.

picocli
Picocli is a modern framework for building powerful, user-friendly, GraalVM-enabled command line apps with ease. It supports colors, autocompletion, subcommands, and more. In 1 source file so apps can include as source & avoid adding a dependency. Written in Java, usable from Groovy, Kotlin, Scala, etc.
His project uses picocli for argument parsing. I briefly looked through the documentation and realized it was pretty similar to the clap crate I used for my project. So I mimicked his other code as well as my own understanding of clap. This part was easy.

Project mention: gRPC Quick start - Coding with streams and bidirectional streaming | dev.to | 2024-06-13
You should see the Server starting on port :50051 message. To interact with the gRPC server, we will use Evans, which is an interactive command-line client for gRPC. You can read more about it here and can install using docker docker run --rm --network host -it ghcr.io/ktr0731/evans --host localhost --port 50051 --reflection. This method is not recommended, but in our case, it will be fine. If everything worked correctly, you must see something like this in your terminal:

kok.nvim
Fast as FUCK nvim completion. SQLite, concurrent scheduler, hundreds of hours of optimization.

PHP Actor is a free alternative that includes the core features you'd expect from an LSP.

It’s very hard to describe without a visual but the gist of it is that the combination of the following 3 packages make it possible dynamically create queries, refine the results to precisely what you want, and then either perform some action on them or just plop them into a buffer for later use. There’s some notion of a type of the result, which means that the actions and results can be richer than just plaintext. Ie: you can imagine a query over a list of commits, where it displays while you’re searching as only the commit shortrev and subject, but where you can viably define a filter on the commit date or commit author. You can then export that list to a temporary buffer, and pressing enter on any given commit will show you the full diff and the full commit message.
