svlint-action

This action checks SystemVerilog source code using svlint.

Inputs

Using svlint on the command line, the list of files to check can be given in one of two ways:

1. Directly, with a list or glob of file paths. For example, svlint foo.sv bar.sv
2. Indirectly, with filelists. For example, svlint -f foo.f -f bar.f

Svlint cannot use both filelists and a list of files at the same time. Similarly, this action cannot use both files and filelists inputs at the same time.

files

Paths to SystemVerilog source files. NOTE: files and filelists are mutually exclusive.

Example Usage

uses: dalance/svlint-action@master
with:
  files: |
    src1.sv
    src2.sv

filelists

The filenames of filelist. NOTE: files and filelists are mutually exclusive. Filelists can include environment variables which are can be given via env.

Example Usage

uses: dalance/svlint-action@master
with:
  filelists: |
    list1.f
    list2.f
env:
  DIR: test

ruleset

Name of a pre-written ruleset, i.e. a wrapper script which uses a bundled TOML configuration. NOTE: If a ruleset is specified, the environment variable SVLINT_CONFIG will be ignored.

As of svlint v0.9.0, the list of bundled rulesets is:

• parseonly
• style
• simsynth
• designintent
• verifintent
• DaveMcEwan-design
• DaveMcEwan-designnaming

See the svlint MANUAL for more details about rulesets (also available as a PDF in a released ZIP).

Example Usage

uses: dalance/svlint-action@master
with:
  ruleset: parseonly
  files: |
    src1.sv
    src2.sv

TOML Configuration

When no ruleset is specified, svlint will search upwards in the filesystem for a file called .svlint.toml and if such a file exists, then it is used as the configuration. This is ideal for projects which only use one custom set of rules, as it only requires placing your .svlint.toml in the root of your repository.

For larger projects which use multiple custom configurations, perhaps one for design and one for verification, the TOML configuration file can be specified using the SVLINT_CONFIG environment variable:

uses: dalance/svlint-action@master
with:
  files: |
    src/design/foo.sv
    src/design/bar.sv
env:
  SVLINT_CONFIG: src/design.svlint.toml

If no configuration file is found, all rules are enabled. This is almost certain to fail - intentionally, to force users to choose some configuration.

Versions of This GitHub Action

To use this action in your repository, your YAML workflow file needs a line like uses: dalance/svlint-action@master. GitHub provides documentation on how to use workflows here. The uses line has the format <GitHubUserName>/<GitHubRepoName>@<GitRef>. That GitRef field may be a tag, branch, commit hash, or (most commonly) the MAJOR component of a tag. Thus, you can use this action in different ways, according to your needs.

• Use the latest release: uses: dalance@svlint-action@latest.
• Use a specific major release: uses: dalance@svlint-action@v1.
• Use the master branch: uses: dalance@svlint-action@master.
• Use a specific commit: uses: dalance@svlint-action@6a447be.
• Use your own fork: uses: JohnDoe@svlint-action@master.

Note: Releases of this action are not necessarily in step with releases of svlint.
