Command Line Reference
This page shows the srb tc --help output for the latest version of Sorbet.
See Command Line Quickstart for an overview of some of the more common options and workflows.
See
srb tc --helpto see the help options for your version of Sorbet. (New options are added and changed all the time.)
Usage
Sorbet: A fast, powerful typechecker designed for Ruby
Usage:
sorbet [options] [[--] <path>...]
INPUT options
-e <string> Treat <string> as if it were the contents of a Ruby file
passed on the command line (default: "")
--e-rbi <string> Like `-e`, but treat <string> as an RBI file (default:
"")
--file <path> Run over the contents of <path>
(Equivalent to passing <path> as a positional argument)
--dir <path> Run over all Ruby and RBI files in <path>, recursively
(Equivalent to passing <path> as a positional argument)
--allowed-extension <ext>[,<ext>...]
Use these extensions to determine which file types Sorbet
should discover inside directories. (default: .rb,.rbi)
--ignore <pattern> Ignores input files that contain <pattern> in their paths
(relative to the input path passed to Sorbet).
When <pattern> starts with `/` it matches against the
prefix of these relative paths; others match anywhere.
Matches must be against whole path segments, so `foo`
matches `foo/bar.rb` and `bar/foo/baz.rb` but not
`foo.rb` or `foo2/bar.rb`.
--no-config Do not load the content of the `sorbet/config` file.
Otherwise, Sorbet reads the `sorbet/config` file and
treats each line as if it were passed on the command
line, unless the line starts with `#`.
To load a <file> as if it were a config file, pass
`@<file>` as a positional arg
--typed {false,true,strict,strong,[auto]}
Force all code to specified strictness level,
disregarding all `# typed:` sigils. For `auto`, uses the
`# typed:` sigil in the file or `false` for files without
a sigil. (default: auto)
--typed-override <filepath.yaml>
Read <filepath.yaml> to override the strictness of
individual files.
Contents must be a map of `<strictness>: ['path1.rb',
...]` pairs.
Can be used to enable type checking for certain files
temporarily without having to add a comment to every
file. (default: "")
OUTPUT options
-q, --quiet Silence all non-critical errors
-P, --progress Draw progressbar
--color {always,never,[auto]}
Use color output. For `auto`: use color if stderr is a
tty (default: auto)
--no-error-count Do not print the `Errors: <N>` summary line
--no-error-sections Only print the first line of every error message
(suppress any additional information below an error). Can
provide substantial speedups when dealing with many
errors
--error-url-base <url-base>
Every error message includes a link created by prefixing
that error's code with <url-base>. Can be used to
maintain docs on Sorbet error codes which are more
relevant to a specific project or company. (default:
https://srb.help/)
--remove-path-prefix <prefix>
Remove the provided <prefix> from all printed paths.
Defaults to the input directory passed to Sorbet, if any.
(default: "")
AUTOCORRECT options
-a, --autocorrect Auto-correct source files with suggested fixes.
Use the `--{isolate,suppress}-error-code` options to
control which corrections to apply
--suggest-unsafe [=<method>(=T.unsafe)]
Include 'unsafe' autocorrects, e.g. those which can be
fixed by wrapping code in `T.unsafe` or using
`T.untyped`. Provide a custom <method> to wrap with
`<method>(...)` instead of `T.unsafe(...)`. This
supersedes certain autocorrects, especially T.must.
--did-you-mean Whether to include 'Did you mean' suggestions in
autocorrects. For large codemods, it's usually better to
avoid spurious changes by setting this to false (default:
true)
--suggest-typed Emit autocorrects to set the `# typed:` sigil in every
file to the highest possible level where no errors would
be reported in that file. Will downgrade the `# typed:`
sigil for any files with errors.
ERROR options
--typed-super Enable typechecking of `super` calls when possible
(default: true)
--check-out-of-order-constant-references
Detect when a constant is referenced early in a file, but
defined later in that file. Does not detect out-of-order
references across file boundaries.
--isolate-error-code <error-code>
Which error(s) to include in reporting. This option can
be passed multiple times. All errors not mentioned will
be silenced.
--suppress-error-code <error-code>
Which error(s) to exclude from reporting. This option can
be passed multiple times.
--suppress-payload-superclass-redefinition-for Fully::Qualified::ClassName
Explicitly suppress the superclass redefinition error for
the specified class defined in Sorbet's payload. May be
repeated.
--experimental-ruby3-keyword-args
Enforce use of new (Ruby 3.0-style) keyword arguments.
(incomplete and experimental)
--enable-experimental-rbs-signatures
Enable experimental support for RBS signatures as inline
comments
--enable-experimental-rbs-assertions
Enable experimental support for RBS assertions as inline
comments
--enable-experimental-requires-ancestor
Enable experimental `requires_ancestor` annotation
--uniquely-defined-behavior
Ensure that every class and module only defines
'behavior' in one file. Ensures that every class or
module can be autoloaded by loading exactly one file.
--stop-after <phase> Stop after completing <phase>. Can be useful for
debugging. Also useful when overwhelmed with errors,
because errors from earlier phases (like resolver) can
cause errors downstream (in inferencer).
Phases: [init, parser, desugarer, rewriter, local-vars,
namer, resolver, cfg, inferencer] (default: inferencer)
METRIC options
--counters Print all internal counters
--counter <counter> Print internal counter for <counter> (repeatable)
--track-untyped [={[nowhere],everywhere,everywhere-but-tests}(=everywhere)]
Include a per-file counter of untyped usages in the
`--print=file-table-<format>` output. This is in addition
to the codebase-wide `types.input.untyped.usages`
counter.
--metrics-file <file> Report counters and some timers to <file>, in JSON
format. (default: "")
--metrics-prefix <string>
String to prefix all metrics with, e.g. `my_org.my_repo`.
(default: ruby_typer.unknown)
--metrics-branch <branch>
Branch to report in metrics export. (default: none)
--metrics-sha <sha> Set the `sha` field to <sha> in the `--metrics-file`
output. (default: none)
--metrics-repo <repo> Set the `repo` field to <repo> in the `--metrics-file`
output. (default: none)
--statsd-host <host> StatsD sever hostname (default: "")
--statsd-prefix <prefix> StatsD prefix (default: ruby_typer.unknown)
--statsd-port <port> StatsD server port (default: 8200)
--metrics-extra-tags <key1>=<value1>,<key2>=<value2>
Extra tags to include in every statsd metric, comma
separated. (default: "")
LSP options
--lsp Start in language server protocol mode (LSP mode)
--lsp-error-cap <cap> Reports no more than <cap> diagnostics (e.g. errors and
informations) to the language client, like VS Code. Can
prevent slowdown triggered by large diagnostic lists. A
<cap> of 0 means no limit. (default: 1000)
--disable-watchman When in LSP mode, disable file watching via Watchman
--watchman-path <path> Path to watchman executable. Will search on `PATH` if
<path> contains no slashes. (default: watchman)
--watchman-pause-state-name <state>
Name of watchman state that halts processing for its
duration (default: "")
--lsp-directories-missing-from-client <path>
Directory prefixes that only exist where the LSP server
is running, not on the client. Useful when running Sorbet
via an `ssh` connection to a remote server, where the
remote server has generated files that do not exist on
the client. References to files in these directories will
be sent as `sorbet:` URIs to clients that understand
them.
--forcibly-silence-lsp-multiple-dir-error
Allow the LSP to start with multiple `--dir` options by
silencing the error. (WARNING: This flag does not address
the known issues with multiple directory support in LSP
mode. You are likely to encounter unexpected behavior.)
LSP FEATURE options
--enable-experimental-lsp-document-formatting-rubyfmt
Enable experimental LSP feature: Document Formatting with
Rubyfmt
--rubyfmt-path <path> Path to the rubyfmt executable used for document
formatting. Will search on `PATH` if <path> contains no
slashes. (default: rubyfmt)

Enable experimental LSP feature: Document Highlight
--enable-experimental-lsp-signature-help
Enable experimental LSP feature: Signature Help
--enable-experimental-lsp-extract-to-variable
Enable experimental LSP feature: Extract To Variable
--enable-all-experimental-lsp-features
Enable every experimental LSP feature. (WARNING: can be
crashy; for developer use only. End users should prefer
to use `--enable-all-beta-lsp-features`, instead.)
--enable-all-beta-lsp-features
Enable (expected-to-be-non-crashy) early-access LSP
features.
PERFORMANCE options
--web-trace-file <file> Generate a trace into <file> in the Trace Event Format
(used by chrome://tracing) (default: "")
