Identifiers and keywords

Keywords are reserved. Identifiers are the names you invent.

Essentials

• An identifier starts with a letter or underscore and continues with letters, digits, or underscores.
• Keywords such as def, struct, trait, var, fn, alias, comptime, and raises cannot be names.
• A trailing underscore is the escape hatch when you must match a keyword.
• Public names are lowercase with underscores. Types use capitalized words.
• Arguments can be keyword-only after a *.

Example

struct Table:
    var columns: Int

def main():
    var table = Table(3)
    print(table.columns)

Keep in mind

Match the standard library's spelling. A project that invents a second convention is harder to read.
