sh-language-server

A language server for the POSIX.1-2024 Shell Command Language.

Installation

Requires Node.js 22 or later.

npm install --global @inknexlab/sh-language-server

External dependencies

Diagnostics use ShellCheck and formatting uses shfmt. Install both separately; if either executable is unavailable, only the corresponding feature is unavailable.

Features

• Completion
• Diagnostics
• Formatting
• Hover
• Semantic tokens

Emacs

Register the server for sh-mode with Eglot:

(require 'eglot)

(add-to-list 'eglot-server-programs
             '(sh-mode . ("sh-language-server" "--stdio")))

Implementation

Uses the POSIX CST from tree-sitter-posix-sh for parsing.
