Why A Generator Built for the Second Run Makes Sense

Description and use

Jostraca enables safe regeneration of generator output, preserving manual edits and supporting multiple file update strategies.

Problem

Developers building generators need a way to regenerate output without erasing manual edits.

Outcome

Jostraca enables safe regeneration of generator output, preserving manual edits and supporting multiple file update strategies.

Workflow

• Install jostraca via npm
• Create a generator script using Jostraca APIs
• Define file generation strategies (write, preserve, present, diff, merge)
• Run the generator
• Edit generated files as needed
• Re-run the generator to see selective updates

Evidence

Any system or product where regeneration should not erase hours of work is a potential use case for Jostraca.
