Module level 

The level builder, and what a level does at run time: prepare, validate, start.

A level is one builder chain: identity and prose, a Fixture describing its files, the answer and requirements that complete it, an optional cd policy and file descriptor rule, and a reference solution. Everything a session needs is a plain public field; everything a level can do is a method here, so the contract lives in one place instead of in each level.

Structs

Level

A level. Build one with level or intro and chain the methods below.

Solution

How a level proves it can be completed: a shell script that does the task.

Enums

LevelKind

Whether a level is graded, or only read.

Start

Where the player is placed when the level starts.

Functions

intro

Start a section intro (N.0): read, then Enter. It has the standard hint (messages::INTRO_HINT) and no start directory unless one is set.

level

Start a regular level: level(8, "Integrační výzva"). The number is explicit, so reordering never renumbers anything.
