runpythonvirtual

It’s a basic Nim wrapper to run Python scripts with a hardcoded interpreter in the same shell while forwarding arguments transparently.

📜 Description of the Current Program

This Nim program is a simple Python launcher:

Hardcoded Executable Path

The path to the Python interpreter inside the virtual environment is written directly into the code.

Example (Windows):

const exePath = r"C:\Programs\PythonVirtualEnv\tuivirtual\Scripts\python.exe"

Command-Line Argument Forwarding

When you run the Nim program with arguments, it forwards them to the Python executable.

Example:

runpython.exe myscript.py arg1 arg2

internally runs:

C:\Programs\PythonVirtualEnv\tuivirtual\Scripts\python.exe myscript.py arg1 arg2

Process Execution in Current Shell

• It uses startProcess(exePath, args=args, options={poParentStreams}).

• This runs the Python script inside the same shell session as the Nim program, sharing stdin/stdout/stderr.

• That means no new window/terminal is opened; it just executes inline.

Output Handling

• Because {poParentStreams} is used, all Python output is visible in the same console window.

• The program waits for Python to finish, then prints "Process finished.".

⚡ Example Run

nim c -r runpython.nim myscript.py
