Just in time for ModCon, I’ve finished migrating six open-source Mojo libraries onto a consistent Mojo 1.0 baseline:
• mojo-asciichart
• mojo-dotenv
• mojo-ini
• mojo-toml
• mojo-yaml
• mojo-benchsuite
They’re all plain Mojo libraries (no MAX), but the migration still involved a fair amount of cross-repo clean-up.
I wrote up the details here:
Mojo 1.0 migration wave: what changed, what worked, and what’s next
The write-up covers:
• why this migration happened now (reducing release friction and the “works in repo A, breaks in repo B” cycle)
• operational consistency (aligned recipe handling and validation flows, and standardised on prek for git hooks while keeping pre-commit compatibility)
• compatibility uplift for key Mojo 1.0 breakpoints (API updates and checked-raises test stabilisation)
• release alignment (all six libraries are now on a shared 0.9.1 library release line, aligned to Mojo 1.0)
• how the work followed Modular’s agentic engineering pattern (human-led architecture + agent-led execution for repetitive cross-repo work)
Happy to hear how others are finding the 1.0 transition…
