Internals

Even though Scala CLI exposes a simple interface to users, quite a number of steps happen when compiling or running even a single source file. This page describes what happens under the hood when you run a Scala CLI command.

Bloop

Scala CLI uses Bloop to compile code. That way, it doesn't interface directly with scalac, and newly released Scala versions work out of the box: there's no need to update Scala CLI itself.

Scala CLI connects to Bloop on the local machine using a domain socket. That domain socket lives under the "Bloop daemon directory", that is OS-dependent, and whose path is printed by scala-cli directories. If no Bloop instance is running, Scala CLI fetches Bloop if necessary (via Coursier), and starts it.

Once it’s connected to Bloop, Scala CLI writes a Bloop project file under a .scala/.bloop directory. This file describes the current Scala CLI project, including its Scala version, dependencies, compiler plugins and options, etc.

It then initiates a BSP connection with Bloop. BSP communication happens on a domain socket too, different than the one above.

That BSP connection then allows Scala CLI to ask Bloop to compile sources, and get diagnostics (warnings / errors) and the compiled byte code.

`.scala-build` directory

In the directory where you run your Scala CLI commands, Scala CLI creates a subdirectory named .scala-build, where it writes:

Bloop project files
generated sources
byte code and TASTy files that result from compiling the user sources

The typical content of the .scala-build directory looks like this:

.scala-build
├── .bloop
│   ├── project_940fb43dce
│   │   ├── bloop-internal-classes
│   │   │   └── main-ZWP3jgllS6y93V4HoGYa2g==
│   │   │       ├── test$.class
│   │   │       ├── test.class
│   │   │       ├── test.tasty
│   │   │       ├── test_sc$.class
│   │   │       ├── test_sc.class
│   │   │       └── test_sc.tasty
│   │   └── project_940fb43dce-analysis.bin
│   ├── project_940fb43dce.json
│   └── project_f643cb0bc2-test.json
└── project_940fb43dce
    ├── classes
    │   └── main
    │       ├── test$.class
    │       ├── test.class
    │       ├── test.tasty
    │       ├── test_sc$.class
    │       ├── test_sc.class
    │       └── test_sc.tasty
    └── src_generated
        └── main
            └── test.scala

In particular, .scala-build/.bloop contains Bloop project files and Bloop's own working directories, and .scala-build/project_* contains byte code, TASTy files, and generated sources.

Home directory for scala-cli

By default, Scala CLI uses the home directory to store Coursier caches, the config database, the working directory for Bloop, and other internal files. To change this default behavior, set the SCALA_CLI_HOME environment variable to point to an existing directory.

Preprocessing

Some source code files that Scala CLI accepts cannot be passed as-is to scalac. This is the case for:

.sc files, which can contain top-level definitions not accepted by scalac
.scala files that have uncommented using directives

In all of those cases, Scala CLI parses the top of those files, and looks for using directives. It then replaces the non-commented using directives with space characters.

As described in Scripts, .sc files are also "wrapped" in an object, and a main class is added to them, so that .sc files can be run as-is, and can access arguments via a special args variable.

In all cases, the resulting processed sources are written in the .scala-build/project_…/src_generated directory, and passed to Bloop from there.

Postprocessing

Because of preprocessing, some outputs we get from scalac might not match the original sources. Processed sources might have shifted line numbers (for .sc files, because of the wrapping in an object), or wrong relative paths (as they're written in src_generated).

For those files, most outputs from scalac are postprocessed, so they match the original sources. That includes:

diagnostics (errors/warnings, whose file names and line/column numbers are adjusted)
byte code (whole line numbers, reported in exception stack traces or used by debuggers, needs to be shifted)
semantic DBs (used for IDE support, whose path fields and positions need to be adjusted)
TASTy files (whose path fields need to be adjusted)

Runner

When running your code, if the code crashes, Scala CLI processes the stack traces of the exception to make them more readable. This is achieved by adding a module (called runner) to the class path, and this module is actually used as the entry point of your application. The Runner class of the runner module starts your main class, catches any exceptions it might throw, and prints it.

Logging

To get a glimpse at what Scala CLI is doing, increase its verbosity with -v. The -v option can be specified up to 3 times, which increases its verbosity level.

Using this option can be a good way to learn how Scala CLI works, though it's mostly meant to help debug issues. When reporting bugs, increasing the verbosity to its maximum level can be helpful.

Here's some example output for the first verbosity level:
