Polyglot

A universal compiler and interpreter wrapper. Detects language by file extension and runs it with the right toolchain.

Supports 50 languages — Python, JavaScript, Go, Java, C, C++, Rust, Ruby, PHP, and more. Implements Auto-Correction of Syntax errors and Auto-Applying Compilation Flags depending on Code.

Install

One-Liner Installation

curl -sSL https://raw.githubusercontent.com/velo4705/polyglot/main/scripts/install.sh | bash

Source Installation

git clone https://github.com/velo4705/polyglot.git && cd polyglot
make build && sudo make install

Usage

polyglot run hello.py          # run any file
polyglot watch app.js          # auto-rerun on changes
polyglot compile hello.cpp     # compile without running
polyglot list                  # show supported languages
polyglot check                 # check installed toolchains
polyglot update                # self-update

Compiler flags

Polyglot auto-detects required compiler flags from your source code:

# Flags detected automatically (e.g. -std=c++17, -pthread, -lm)
polyglot run hello.cpp

# Override or add flags manually
polyglot run --compile-flags "-O3 -march=native" hello.cpp

Dry run

polyglot run --dry-run hello.c   # see what would execute without running

Stdin

echo 'print("hello")' | polyglot run --lang Python

Arguments

polyglot run --args "arg1 arg2" hello.py
