FAQ

Is Block a programming language?

Block is both a workflow language and an execution engine. Its native core supports variables, expressions, control flow, collections, functions, and built-ins. Its defining feature is coordinating existing runtimes in one explicit document.

Does Block replace Python or JavaScript?

No. Block lets each stage keep using the runtime that fits it best.

Do I need to install every runtime?

No. Install only the runtimes used by your files. Native Block programs do not need Python or Node.js.

Why did my script fail to run?

Start with:

block check .\your-file.blk
block runtimes
block doctor

Then verify matching tags, file paths, edition support, configuration flags, and host runtime availability.

Can Block run untrusted code safely?

No. Block invokes host runtimes and should be treated like a code launcher. Use source review, antivirus scanning, least privilege, and isolated test environments.

How can I contribute?
