Configuration

Language server

svls uses .svls.toml at the root of repository. The example of .svls.toml is below:

[verilog]
include_paths = ["src/header"]
defines = ["DEBUG", "VAR=1"]
plugins = ["path/to/libfoo.so", "path/to/libbar.so"]

[option]
linter = true

[verilog] section

include_paths is include paths from the root of repository. defines is define strings. plugins is paths to svlint plugins from the working directory.

[option] section

linter shows whether linter feature is enabled.

Linter

Linter uses .svlint.toml at the root of repository. If .svlint.toml can't be used, all lint rules are enabled. Please see svlint#configuration for the detailed information.
