vscode settings for Go Rust, Solidity and Python

Each language should have the following 3 components:

1. The language server.
2. The formatter.
3. The linter.

Each component has a binary and a vscode extension.

1. Go

First of all, install the go compiler by following the official doc https://go.dev/doc/install.

1.1 Language Server

Install the official go language server binanry gopls:

go install golang.org/x/tools/gopls@latest

Install the official vscode plugin vscode-go. This plugin can automatically install the gopls binary too.

1.2 Formatter

We are going to use gofumpt-style formatting instead of the default gofmt, first install it:

go install mvdan.cc/gofumpt@latest

Then add the following configuration to settings.json:

"editor.formatOnSave": true,
"files.autoSave": "onFocusChange",
"go.formatTool": "gofumpt",
"gopls": {
    "formatting.gofumpt": true
}

1.3 Linter

Choose staticcheck as the Go linter. First install it:

go install honnef.co/go/tools/cmd/staticcheck@latest

Then add the following configuration to settings.go:

"go.lintTool": "staticcheck",
"go.lintOnSave": "file",

2. Rust

First of all, install the Rust compiler and cargo:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y --default-toolchain nightly

2.1 Language Server

Choose rust-analyzer because it is much better than the official language server rls.

First install its binary:

rustup component add rust-src rust-analyzer-preview

Then install its vscode extension matklad.rust-analyzer. This plugin can automatically install the rust-analyzer binary too.

2.2 Formatter

rust-analyzer is the formatter by default.

2.3 Linter

rust-analyzer is the linter by default.

3. Solidity

First of all, install the solc:

brew install solidity

3.1 Language Server

The solc has a --lsp parameter, which makes it a language server.

So we only need to install the vscode extension JuanBlanco.solidity.

3.2 Formatter

"[solidity]": {
    "editor.defaultFormatter": "JuanBlanco.solidity"
},

3.3 Linter

First, install the binary solhint,

brew install solhint

Then add the following configuration to settings.json:

"solidity.linter": "solhint",

4. Python

First of all, we need to install a Python interpreter, I prefer anaconda::

brew install --cask anaconda

4.1 Language Server

We choose the Microsoft pylance as the Python language server.

First, install the ms-python.python extension.

This extension can automatically install the Pylance binary, and it also install the Pylance and Jupyter extensions.

Then add the following configuration to settings.json:

"python.languageServer": "Pylance",
"python.analysis.typeCheckingMode": "strict",

4.2 Formatter

Use black as the formatter, install it first:

conda install black -c conda-forge

Then add the following configuration to settings.json:

"python.formatting.provider": "black",

4.3 Linter

Use pylint as the linter, install it first:

conda install pylint -c conda-forge

Then add the following configuration to settings.json:

"python.linting.pylintEnabled": true,
