ShellCheck for Visual Studio Code
Integrates ShellCheck into VS Code, a linter for Shell scripts.
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, arm, arm64)
- macOS (x86_64, arm64)
- 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.
Install Extension command from Command Palette.
- Search and choose
There are various options that can be configured by making changes to your user or workspace preferences.
Default options are:
"shellcheck.executablePath": "", // Priority: user defined > bundled shellcheck binary > "shellcheck"
"shellcheck.ignoreFileSchemes": ["git", "gitfs", "output"]
shellcheck.ignorePatterns works exactly the same as
search.exclude, read more about glob patterns here
Fix all errors on save
The auto-fixable errors can be fixed automatically on save by using the following configuration:
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
onSave if you want to lint only when the file is saved (works best if auto-save is on).
"shellcheck.run": "onType" // also: "onSave"
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:
Using Docker version of shellcheck
In order to get it to 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):
exec docker run --rm -i -v "$PWD:/mnt:ro" koalaman/shellcheck:latest "$@"
For example, you can place it at
shellcheck.sh in the root of your workspace and ensure that it have execution permission with
chmod +x shellcheck.sh. And then, you can configure the extension to use it:
// use the shim as shellcheck executable
// you may also need to turn this option on, so shellcheck in the container
// can access all the files in the workspace
Integrating other VS Code extensions
This extension provides a small API, which allows other VS Code extensions to interact with the ShellCheck extension. For details, see API.md.
This extension is based on @hoovercj's Haskell Linter.
