Magic Scheme

MORE DETAIL PLEASE REFER GITHUB PAGE.

This extension adds support for Scheme(r6rs standard) to VS Code. With the help of scheme-langserver, we're proud to say that Magic Scheme is much better than many counterparts, which includes even Racket extensions.

NOTE: PLEASE ALWAYS USE LATEST VERSION SCHEME-LANGSERVER.

Please make sure: before you start this extension, you have to do fully setting up and configurations here.

Features

Magic Scheme does

• Support Scheme LSP through scheme-langserver, which brings jump to definition, auto complete, type inference(early stage) and more. Especially, Magic Scheme can handle local identifiers and partial evaluation technique, which are not provided by many counterparts.
• Support Scheme project with through AKKU, which make you possible to load project depdendencies in REPL or directly run scheme script in terminal.
• Support highlighting of nearly all of the r6rs standard functions and Chez Scheme functions.

LSP

Magic Scheme now supports scheme-langserver. The current features are:

• Jump to definition

Especially, I must first recommend you with scheme-langserver's magic local identifier handling. Because in many other counterparts, you can never goto local binding's definition like the a in following:

(let ([a 1])
 a
)

• Auto complete

In further, thorough scheme-langserver, Magic Scheme can auto complete a with a-full-name-identifier in such cases:

(let ([a-full-name-identifier 1])
 a
)

• Find references

• Hover

Scheme-langserver truely responses results, however, I have no idea that VScode doesn't display.

I'm working on providing more details in this section: stay tuned!

Scheme Project

You can directly run scheme script with project environment after typing Alt+Shift+Enter, or you may Ctrl+Shift+P and input command magic-scheme.runSchemeScript; The result shows scheme --script ${currentFile}:

You can directly load scheme project environment in REPL after typing Alt+Shift+Enter, or you may Ctrl+Shift+P and input command magic-scheme.runSchemeRepl; The result shows an REPL and you may import AKKU managed environemnts without further configurations.

Syntax Highlighting

Setting Up & Some Configuration

The followings are mainly focus on x64-based linux operating system. As for other OSs, you may notice the following tips:

1. If you're using nixos, you may directly search scheme-langserver here. it will directly install an executable binary file. And this file is softly linked in bash $PATH as scheme-langserver.
2. If you're using MacOS, Windows or any other related environments, I suppose you're an advanced user and you may refer scheme-langserver's documentation in order to compile scheme-langserver manually.
3. Chez Scheme has Windows and MacOS version, but I've never tested them. So, I mean for Windows, you'd better use WSL/WSL2; for MacOS, it seems not very different from Linux.
4. AKKU is not native on Windows.
5. For nixos, you may be able to directly install all your needs.
6. Any other corner cases, you may refer softwares' documentations.

Disable Conflict Plugins

I'm so sorry Magic Scheme has some conficts with Chez-Scheme-VsCode plugin. So, maybe you need to disable it.

Get Scheme-langserver

You may directly download latest executable file here. This file you may memory its path as {path-to-run}, and you must set configuration magic-scheme.scheme-langserver.path as it.

Get Scheme

Magic Scheme supports r6rs standard scheme. But apparently I can't fully tests all implementations. As myself, I recommend with Chez Scheme, and you may install it as following:

wget https://github.com/cisco/ChezScheme/releases/download/v10.0.0/csv10.0.0.tar.gz
tar -xf csv10.0.0.tar.gz && cd csv10.0.0
# Install dependencies: `libncurses5-dev`
./configure --threads --kernelobj --disable-x11
make && sudo make install

Get AKKU

AKKU is a package manager for Scheme. It grabs hold of code and shakes it vigorously until it behaves properly. Magic Scheme facilitates AKKU to manage scheme projects. To install AKKU, you may follow:

wget https://gitlab.com/-/project/6808260/uploads/094ce726ce3c6cf8c14560f1e31aaea0/akku-1.1.0.amd64-linux.tar.xz
tar -xf akku-1.1.0.amd64-linux.tar.xz && cd akku-1.1.0.amd64-linux
bash install

For Developeer

1. For Nixos, after install yo and generator-code, should

export PATH=$PATH:./node_modules/.bin/
