Setup of tested language servers

JavaScript with Flow static type checker

• Prerequisites:
  • Node.js
• Recommended:
  • Prettier

Install language server, and create executable to enable server in juCi++:

npm install -g flow-language-server

echo '#!/bin/bash
flow-language-server --stdio' > /usr/local/bin/javascript-language-server

chmod 755 /usr/local/bin/javascript-language-server

• Additional setup within a JavaScript project:
  • Add a .prettierrc file to enable style format on save

Python3

• Prerequisites:
  • In juCi++ preferences, set project.python_command to PYTHONUNBUFFERED=1 python3
  • Python3

    • MacOS: Jedi does not yet support Python 3.6, but you can install latest 3.5 version:

      brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/f2a764ef944b1080be64bd88dca9a1d80130c558/Formula/python.rb

Install language server, and create symbolic link to enable server in juCi++:

pip3 install python-language-server[rope,pycodestyle,yapf] pyls-mypy

ln -s `which pyls` /usr/local/bin/python-language-server

• Additional setup within a Python project:
  • Add a setup file, for instance: printf '[pycodestyle]\nmax-line-length = 120\n\n[yapf]\nCOLUMN_LIMIT = 120\n' > setup.cfg
  • Add an empty .python-format file to enable style format on save

Rust

• Prerequisites:
  • Rust

Install language server, and create symbolic link to enable server in juCi++:

rustup update
rustup component add rls-preview rust-analysis rust-src

ln -s `rustc --print sysroot`/bin/rls /usr/local/bin/rust-language-server

• Additional setup within a Rust project:
  • Add an empty .rust-format file to enable style format on save
