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

# usually as root:
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

TypeScript or JavaScript without Flow

  • Prerequisites:
    • Node.js
  • Recommended:

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

npm install -g typescript-language-server typescript

# usually as root:
echo '#!/bin/bash
`npm root -g`/typescript-language-server/lib/cli.js --stdio' > /usr/local/bin/javascript-language-server

chmod 755 /usr/local/bin/javascript-language-server
rm -f /usr/local/bin/typescript-language-server
cp /usr/local/bin/javascript-language-server /usr/local/bin/typescript-language-server
cp /usr/local/bin/javascript-language-server /usr/local/bin/typescriptreact-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]

# usually as root:
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 component add rust-src

git clone https://github.com/rust-analyzer/rust-analyzer
cd rust-analyzer
cargo xtask install --server

# usually as root:
ln -s ~/.cargo/bin/rust-analyzer /usr/local/bin/rust-language-server
  • Additional setup within a Rust project:
    • Add an empty .rust-format file to enable style format on save
