Tereus transpilers mostly works like a compiler but instead of generating machine code, it generates text.
We use ANLTR to parse the source code into a AST (Abstract Syntax Tree).
ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files.
You can use the following command to convert a C file to Go:
go run cmd/cli/main.go <input.c>The transpiler is designed to listen on a queue for C files to convert.
First, you need to copy the .env.example file to .env and fill in the values.
The Kafka endpoint and S3 bucket should be shared with the Tereus API.
You can then start the worker with:
➜ go run .

INFO[0000] Connecting to MinIO...
