Building packages

Build an application package

Given a file named "pen.json" with:

{
  "type": "application",
  "dependencies": {
    "Os": "pen:///os"
  }
}

And a file named "main.pen" with:

import Os'Context { Context }

main = \(ctx context) none {
  none
}

When I successfully run pen build

Then I successfully run ./app.

Build a library package

Given a file named "pen.json" with:

{
  "type": "library",
  "dependencies": {}
}

And a file named "Foo.pen" with:

f = \(x number) number {
  x
}

When I run pen build

Then the exit status should be 0.

Cross-build an application package

Given a file named "pen.json" with:

{
  "type": "application",
  "dependencies": {
    "Os": "pen:///os-sync"
  }
}

And a file named "main.pen" with:

import Os'Context { Context }

main = \(ctx context) none {
  none
}

And I successfully run rustup target add <target>

When I successfully run pen build --target <target>

Then the exit status should be 0.

Examples

target
i686-unknown-linux-musl
x86_64-unknown-linux-musl
aarch64-unknown-linux-musl
wasm32-wasi

Cross-build a library package

Given a file named "pen.json" with:

{
  "type": "library",
  "dependencies": {}
}

And a file named "Foo.pen" with:

f = \(x number) number {
  x
}

And I successfully run rustup target add <target>

When I successfully run pen build --target <target>

Then the exit status should be 0.

Examples

target
i686-unknown-linux-musl
x86_64-unknown-linux-musl
aarch64-unknown-linux-musl
wasm32-wasi

Build an application package again

Given a file named "pen.json" with:

{
  "type": "application",
  "dependencies": {
    "Os": "pen:///os"
  }
}

And a file named "main.pen" with:

import Os'Context { Context }

main = \(ctx context) none {
  none
}

And I successfully run pen build

And I successfully run ./app

And the stdout from "./app" should contain exactly ""

When a file named "main.pen" with:

import Os'Context { Context }
import Os'File

main = \(ctx context) none {
  _ = File'Write(ctx.Os, File'StdOut(), "hello")

  none
}

And I successfully run pen build

Then I successfully run ./app

And the stdout from "./app" should contain exactly "hello".
