The compile command compiles a Python function into a self-contained binary predictor that runs natively on server, desktop, mobile, and web.

​
Usage

$ muna compile [OPTIONS] PATH
ArgumentDescription
PATHPath to your Python source file

​
Options

OptionDescription
--overwriteDelete any existing predictor with the same tag before compiling

​
Compiling a Function

First, define a Python function with the @compile decorator:
greeting.py
from muna import compile

@compile(
    tag="@your-username/greeting",
    description="Say a friendly greeting."
)
def greeting(name: str) -> str:
    return f"Hey there {name}! We're glad you're using Muna."
Then compile it: 
# 🔥 Compile the predictor
$ muna compile greeting.py

​
Overwriting Predictors

If you’ve already compiled a predictor with the same tag, use --overwrite to replace it: 
# 🔥 Recompile and overwrite existing predictor
$ muna compile --overwrite greeting.py
Overwriting a predictor immediately replaces the previous version. Any applications using the predictor will start using the new version on their next prediction.

​
What Happens During Compilation

When you run muna compile, the CLI:
  1. Parses your Python source file
  2. Identifies functions decorated with @compile
  3. Uploads the source code to Muna
  4. Performs code generation and transpilation to native C++
  5. Compiles binaries for all supported platforms
Compilation time varies based on function complexity. Check the status at muna.ai/predictors.
