Info Schema
Exercises in soliditylings are configured declaratively in an info.toml struct. Whenever you want to add, subtract, or reorder the training exercises inside of the project, all it takes is editing info.toml.
Structure
The schema relies on an array of [[exercises]] objects. Below is a sample block inside the TOML syntax that explains everything about how to configure an exercise:
[[exercises]]
name = "intro1"
path = "exercises/00_intro/intro1.sol"
mode = "compile"
hint = """
Just run the exercise to see the welcome message!
Fix the syntax error to progress.
"""
Each exercise has four main fields.
name
(String) The internal reference name for your current exercise. It must be unique across the configuration map.
path
(String) An exact path referencing where the underlying .sol source code for this specific test case or smart contract file resides within the /exercises/ structure.
mode
(String) Tells the CLI how to handle the file.
compile: The runner will just try tosolccompile this file cleanly. Success means zero compiler complaints.test: The file requires test cases inside or uses a Forge-like environment. The runner automatically executes the Solidity tests and fails natively if assertions trigger a revert.
