Setup of tested language servers

JavaScript with Flow static type checker

  • Prerequisites:
    • Node.js
  • Recommended:

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

npm install -g flow-bin

echo '#!/bin/bash
flow lsp' > /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:
    • Python3
    • In juCi++ preferences, set project.python_command to PYTHONUNBUFFERED=1 python3

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

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

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 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
