Examples

This directory contains runnable Maithili DSL (.dmai) programs that demonstrate the language. Run any of them with either entry point:

python_maithili examples/hello.dmai
# or, without installing the console script:
python -m maithili_dsl examples/hello.dmai

Note: error.dmai is intentionally broken — it is used by CI to verify that the linter/transpiler correctly rejects invalid programs. It is expected to exit with a non-zero status and should not be run as a normal example.

hello.dmai

Prints a greeting in Maithili.

• Keywords/modules shown: कार्य (function definition), छपाउ (print), top-level call.

• Expected output:

  हम मैथिली में कोड कऽ रहल छी।
  

person.dmai

shopping_list.dmai

Builds a list, appends/removes items, iterates, and computes a sum and average.
