when the compiler is run from the command-line.

The command-line provides two options to control the execution of passes:

- `-p, --pass`: Execute this pass or alias. Overrides default alias.
- `-d, --disable-pass`: Disable this pass or alias. Takes priority over `-p`.

cargo run -- examples/futil/simple.futil -p all -d static-timing
```

If you want to work with passes interactively (for instance, you only care about
a pass far into the `all` sequence, and it is impractical to pass 20 `-p`
options), you can [visualize them](./dev/calyx-pass-explorer.md) with the `calyx-pass-explorer` tool.

## Providing Pass Options

Some passes take options to control their behavior. The `--list-passes` command prints out the options for each pass. For example, the `tdcc` pass has the following options:

```

The option allows us to change the behavior of the pass. To provide a pass-specific option, we use the `-x` switch:

```
cargo run -- examples/futil/simple.futil -p tdcc -x tdcc:dump-fsm
```

Note that we specify the option of `tdcc` by prefixing it with the pass name and a colon.


## Specifying Primitives Library

The compiler implementation uses a standard library of components to compile
programs.
The only standard library for the compiler is located in:

```
<path to Calyx repository>/primitives
```

Specify the location of the library using the `-l` flag:

```
cargo run -- -l ./primitives
```

Enter [`calyx-pass-explorer`](https://github.com/calyxir/calyx/tree/main/tools/calyx-pass-explorer).
It's a command line tool that provides an interactive interface for visualizing
how different passes affect the source code.
It's been used to debug and develop new compiler passes as well as implement new features in the compiler, so I hope you can find it useful too!

That's a lot better, but it's still quite a bit of information.
Let's break it down.
