Cairo by example

• First setup using Nile which makes managing files and command line calls to StarkNet simple.
• Second have a look at how pytest works
• After you have set everything up, to run the examples:
  • Open two terminals in the project folder and run source env/bin/activate
  • In one run nile node to start a local devnet.
  • In the other run the commands in the examples.

Examples of different elements in Cairo and StarkNet.

• Hello, World!
• First application
• Array
• Data types
• Variables
• Read and write values
• Read and write tuples
• Currency
• Constructor
• Custom imports
• Contract calls
• Array argument
• Array returns
• Struct returns

YMMV Examples

These examples have core principles, but have not been tested with cairo-lang version >0.5.0 and may not compile. I will move them to the section above after checking them and adding nile-based notes.
