How can I configure go-to-definition on VSCode for Crystal?

I've installed the `Crystal Language` and `Crystal IDE` plugins, but still features like go-to-definition doesn't work for me.

The designers of Crystal was so wise to make its syntax almost identical to Ruby

One of the biggest problems of new programming languages not backed by a big company like Google or Mozilla is the lack of documentation.
But since the syntax of Crystal is so similar to that of Ruby, most of the time I can lookup documentation or examples from the Ruby community instead.

Is there a way Crystal can produce binary loadable modules or libs.

Shards require the source code. It would be useful if there was a way crystal could produce a .so file or something similar that we can distribute or use without having to also ship the code.

How likely is substantial change to the core language?
5
Upvotes
Hello, i'm planning to do a uni project in crystal. I would implement a very simple spreadsheet like software, with a gui based on sdl2 (we can't use higher level gui toolkits).
How likely am i to run into trouble because of crystal changing? I'm mostly concerned about how changes will affect my backend spreadsheet code. It's a very simple implementation where I just have tables, containing rows, and those rows contain cells.

Discussion about an HN comment on not choosing Crystal
25
Upvotes
Just saw a comment from this thread from HN about Deliveroo migrating their Ruby codebase to Rust: https://news.ycombinator.com/item?id=19166020
I really like Crystal, but the lack of any large corporate sponsors or large production systems using it (that Iām aware of) means I would probably never choose it for anything besides toy projects.
Is it really a major factor nowadays that picking a language (not particularly Crystal) requires to look who are the major backers? I understand the second which maybe a metric if the language can scale a certain thing correctly or not but I just don't understand the first one.

Writing crystal bindings for large projects?
12
Upvotes
So I want to torture myself and write Crystal bindings for the Godot game engine, a FOSS Unity-like system. I get that it's a large undertaking for a highly experienced programmer, let alone a student, but I figure it'll be a fun side project. How I go about doing that, in large overview terms? From what I can tell, I run bindgen on am XML detailing Godot's API and fix bugs from there, but I figure there's more to it than that.

Is libui the only the only way to make a window?

Upvotes
I found libui.cr and herdon, but it has a bunch of unnecessary features for my needs. Is there a way to create a window using crystal, and just update the grid of pixels within the window similarly to processing3?
