We're here to help readers as much as writers.</p> </li> <li> <p dir="auto"><strong>Feel useful, not burdensome</strong></p> <p dir="auto">While it is explicit, we are putting effort into making it concise. This shows in multiple ways:</p> <ul dir="auto"> <li>error messages should be clear</li> <li>verbosity should be compensated with more safety</li> </ul> </li> <li> <p dir="auto"><strong>As simple as possible, but powerful enough</strong></p> <p dir="auto">Overall, we are not strong believers in super-complex type systems. They have their place, and we need a fair amount of expressive power to model (enough) real Ruby code, but all else being equal we want to be simpler. We believe that such a system scales better, and—most importantly—is easier for our users to learn &amp; understand.</p> </li> <li> <p dir="auto"><strong>Compatible with Ruby</strong></p> <p dir="auto">In particular, we don't want a new syntax. Existing Ruby syntax means we can leverage most of our existing tooling (editors, etc). Also, the point of Sorbet is to gradually improve an existing Ruby codebase. No new syntax makes it easier to be compatible with existing tools.</p> </li> <li> <p dir="auto"><strong>Scales</strong></p> <p dir="auto">On all axes: execution speed, number of collaborators, lines of code, codebase age. We work in large Ruby codebases, and they will only get larger.</p> </li> <li> <p dir="auto"><strong>Can be adopted gradually</strong></p> <p dir="auto">In order to make adoption possible at scale, we cannot require every team or project to adopt Sorbet all at once. Sorbet needs to support teams adopting it at different paces.</p> </li> </ol> <div class="markdown-heading" dir="auto"><h2 tabindex="-1" class="heading-element" dir="auto">Quickstart</h2><a id="user-content-quickstart" class="anchor" aria-label="Permalink: Quickstart" href="#quickstart"><svg class="octicon octicon-link" viewBox="0 0 16 16" version="1.1" width="16" height="16" aria-hidden="true"><path d="m7.775 3.275 1.25-1.25a3.5 3.5 0 1 1 4.95 4.95l-2.5 2.5a3.5 3.5 0 0 1-4.95 0 .751.751 0 0 1 .018-1.042.751.751 0 0 1 1.042-.018 1.998 1.998 0 0 0 2.83 0l2.5-2.5a2.002 2.002 0 0 0-2.83-2.83l-1.25 1.25a.751.751 0 0 1-1.042-.018.751.751 0 0 1-.018-1.042Zm-4.69 9.64a1.998 1.998 0 0 0 2.83 0l1.25-1.25a.751.751 0 0 1 1.042.018.751.751 0 0 1 .018 1.042l-1.25 1.25a3.5 3.5 0 1 1-4.95-4.95l2.5-2.5a3.5 3.5 0 0 1 4.95 0 .751.751 0 0 1-.018 1.042.751.751 0 0 1-1.042.018 1.998 1.998 0 0 0-2.83 0l-2.5 2.5a1.998 1.998 0 0 0 0 2.83Z"></path></svg></a></div> <ol dir="auto"> <li> <p dir="auto">Install the dependencies</p> <ul dir="auto"> <li><code>brew install bazel autoconf coreutils parallel</code></li> </ul> </li> <li> <p dir="auto">Clone this repository</p> <ul dir="auto"> <li><code>git clone https://github.com/sorbet/sorbet.git</code></li> <li><code>cd sorbet</code></li> </ul> </li> <li> <p dir="auto">Build Sorbet</p> <ul dir="auto"> <li><code>./bazel build //main:sorbet --config=dbg</code></li> </ul> </li> <li> <p dir="auto">Run Sorbet!</p> <ul dir="auto"> <li><code>bazel-bin/main/sorbet -e "42 + 'hello'"</code></li> </ul> </li> </ol> <div class="markdown-heading" dir="auto"><h2 tabindex="-1" class="heading-element" dir="auto">Learning how Sorbet works</h2><a id="user-content-learning-how-sorbet-works" class="anchor" aria-label="Permalink: Learning how Sorbet works" href="#learning-how-sorbet-works"><svg class="octicon octicon-link" viewBox="0 0 16 16" version="1.1" width="16" height="16" aria-hidden="true"><path d="m7.775 3.275 1.25-1.25a3.5 3.5 0 1 1 4.95 4.95l-2.5 2.5a3.5 3.5 0 0 1-4.95 0 .751.751 0 0 1 .018-1.042.751.751 0 0 1 1.042-.018 1.998 1.998 0 0 0 2.83 0l2.5-2.5a2.002 2.002 0 0 0-2.83-2.83l-1.25 1.25a.751.751 0 0 1-1.042-.018.751.751 0 0 1-.018-1.042Zm-4.69 9.64a1.998 1.998 0 0 0 2.83 0l1.25-1.25a.751.751 0 0 1 1.042.018.751.751 0 0 1 .018 1.042l-1.25 1.25a3.5 3.5 0 1 1-4.95-4.95l2.5-2.5a3.5 3.5 0 0 1 4.95 0 .751.751 0 0 1-.018 1.042.751.751 0 0 1-1.042.018 1.998 1.998 0 0 0-2.83 0l-2.5 2.5a1.998 1.998 0 0 0 0 2.83Z"></path></svg></a></div> <p dir="auto">We've documented the <a href="/sorbet/sorbet/blob/master/docs/internals.md">internals of Sorbet</a> in a separate doc.

It checks the structure of the file before and after the update to determine if the change is covered under the fast path. If it is, it performs further processing to determine the set of files that need to be type checked.</p> <p dir="auto">LSP tests can define file updates in <code>&lt;name&gt;.&lt;version&gt;.rbupdate</code> files which contain the contents of <code>&lt;name&gt;.rb</code> after the update occurs. For example, the file <code>foo.1.rbupdate</code> contains the updated contents of <code>foo.rb</code>.</p> <p dir="auto">If the test contains multiple files by using a <code>__</code> suffixed prefix, then all rbupdates with the same version will be applied in the same update. For example, <code>foo__bar.1.rbupdate</code> and <code>foo__baz.1.rbupdate</code> will be applied simultaneously to update <code>foo__bar.rb</code> and <code>foo__baz.rb</code>.</p> <p dir="auto">Inside <code>*.rbupdate</code> files, you can assert that the slow path ran by adding a line with <code># assert-slow-path: true</code>. You can assert that the fast path ran on <code>foo__bar.rb</code> and <code>foo__baz.rb</code> with <code>#assert-fast-path: foo__bar.rb,foo__baz.rb</code>.</p> <p dir="auto">Note that the default behavior when testing multi-file updates (e.g., <code>*__1.1.rbupdate</code> + <code>*__2.1.rbupdate</code>) is to include all the files in the file update that is created and sent to the LSP server. When testing changes that assert whether the right files were typechecked on the fast path with <code>assert-fast-path</code>, you also likely want to declare which files <strong>should not</strong> be included in the file edit, leaving Sorbet to figure out the subset of files to be typechecked. <strong>But</strong> regardless of whether a file was included in the update set, you likely want to assert that error occur at certain points inside the file. For this, you can use <code># exclude-from-file-update: true</code> inside an <code>rbupdate</code> file. Note that when using this, the act of adding the <code>exclude-from-file-update</code> assertion in the <code>rbupdate</code> will have the effect of shifting all the <code>error</code> assertions off by one line compared to where the LSP server will be reporting those errors. To work around this, you should leave a spacer line in the previous file, so that the <code>exclude-from-file-update</code> assertion replaces the spacer line, instead of being inserted into the file as a completely new line. Search for <code>spacer</code> in some of the <code>fast_path</code> tests to see an example.</p> <p dir="auto">To craft an update to an RBI file, use <code>.rbiupdate</code> instead of <code>.rbupdate</code>, unless you mean to simulate the effect of converting an RBI file to an RB file.</p> <div class="markdown-heading" dir="auto"><h3 tabindex="-1" class="heading-element" dir="auto">LSP recorded tests</h3><a id="user-content-lsp-recorded-tests" class="anchor" aria-label="Permalink: LSP recorded tests" href="#lsp-recorded-tests"><svg class="octicon octicon-link" viewBox="0 0 16 16" version="1.1" width="16" height="16" aria-hidden="true"><path d="m7.775 3.275 1.25-1.25a3.5 3.5 0 1 1 4.95 4.95l-2.5 2.5a3.5 3.5 0 0 1-4.95 0 .751.751 0 0 1 .018-1.042.751.751 0 0 1 1.042-.018 1.998 1.998 0 0 0 2.83 0l2.5-2.5a2.002 2.002 0 0 0-2.83-2.83l-1.25 1.25a.751.751 0 0 1-1.042-.018.751.751 0 0 1-.018-1.042Zm-4.69 9.64a1.998 1.998 0 0 0 2.83 0l1.25-1.25a.751.751 0 0 1 1.042.018.751.751 0 0 1 .018 1.042l-1.25 1.25a3.5 3.5 0 1 1-4.95-4.95l2.5-2.5a3.5 3.5 0 0 1 4.95 0 .751.751 0 0 1-.018 1.042.751.751 0 0 1-1.042.018 1.998 1.998 0 0 0-2.83 0l-2.5 2.5a1.998 1.998 0 0 0 0 2.83Z"></path></svg></a></div> <p dir="auto">It is possible to record an LSP session and use it as a test.

In particular, the <code>./compile_commands.json</code> references files in Bazel's <code>opt</code> configuration (e.g., whatever was last built with <code>-c opt</code> / <code>--compilation_mode=opt</code>). If you're seeing stale errors, consider running a command like <code>./bazel build //main:sorbet -c opt</code>.</p> <p dir="auto">You are encouraged to play around with various clang-based tools which use the <code>compile_commands.json</code> database.
