ShellCheck for Visual Studio Code

Integrates ShellCheck into VS Code, a linter for Shell scripts.

Quick start

Disclaimer

vscode-shellcheck (this "extension"), requires shellcheck (the awesome static analysis tool for shell scripts) to work.

Since v0.10.0, precompiled shellcheck binaries are bundled for these platforms:

• Linux (x86_64)
• macOS (x86_64)
• Windows: precompiled 32bit binary will be used on both 32bit and 64bit Windows, please note that this requires you have WoW64 enabled, although it's not a problem for Desktop users.

Requirements

1. Run Install Extension command from Command Palette.
2. Search and choose shellcheck.

Options

There are various options that can be configured by making changes to your user or workspace preferences.

Default options are:

{
  "shellcheck.enable": true,
  "shellcheck.enableQuickFix": true,
  "shellcheck.run": "onType",
  "shellcheck.executablePath": "", // Priority: user defined > bundled shellcheck binary > "shellcheck"
  "shellcheck.exclude": [],
  "shellcheck.customArgs": [],
  "shellcheck.ignorePatterns": {
    "**/*.xonshrc": true,
    "**/*.xsh": true,
    "**/*.zsh": true,
    "**/*.zshrc": true,
    "**/zshrc": true,
    "**/*.zprofile": true,
    "**/zprofile": true,
    "**/*.zlogin": true,
    "**/zlogin": true,
    "**/*.zlogout": true,
    "**/zlogout": true,
    "**/*.zshenv": true,
    "**/zshenv": true,
    "**/*.zsh-theme": true
  },
  "shellcheck.ignoreFileSchemes": ["git", "gitfs"]
}

shellcheck.ignorePatterns

The shellcheck.ignorePatterns works exactly the same as search.exclude, read more about glob patterns here

For example:

{
  "shellcheck.ignorePatterns": {
    "**/*.zsh": true,
    "**/*.zsh*": true,
    "**/.git/*.sh": true,
    "**/folder/**/*.sh": true
  }
}

Fix all errors on save

The auto-fixable errors can be fixed automatically on save by using the following configuration:

{
  "editor.codeActionsOnSave": {
    "source.fixAll.shellcheck": true
  }
}

Alternatively, you can fix all errors on demand by running the command Fix All in the VS Code Command Palette.

Lint onType or onSave

By default the linter will lint as you type. Alternatively, set shellcheck.run to onSave if you want to lint only when the file is saved (works best if auto-save is on).

{
  "shellcheck.run": "onType" // also: "onSave"
}

Excluding Checks

By default all shellcheck checks are performed and reported on as necessary. To globally ignore certain checks in all files, add the "SC identifiers" to shellcheck.exclude. For example, to exclude SC1017:

{
  "shellcheck.exclude": ["1017"]
}

Using Docker version of shellcheck

In order to get it work, you need a "shim" script, and then, just remember, do not try to construct command line arguments for shellcheck yourself.

Here is a simple "shim" script to get start with (See discussion: #24):

#!/bin/bash

exec docker run --rm -i -v "$PWD:/mnt:ro" koalaman/shellcheck:v0.7.0 "$@"
