First Window

Picture
This is the very first window Ooloi has opened. Ever.

Not a console command or REPL experiment - a window created through the infrastructure completed yesterday (ADR-0031), using the new UI Specification Format (ADR-0042) that amongst other things makes all UI elements accessible to plugins as first-class citizens.

Another quiet decision: localisation from the start. ADR-0039 establishes that every UI string is translatable from day one, using GNU gettext's standard .po format. The tooling ecosystem is mature: Poedit, Crowdin, Transifex, Weblate, Lokalise, POEditor, OmegaT. Translators know these tools. Workflows exist. Nothing proprietary, nothing invented here.
​
Not retrofitted later. Built in.

Peter, will it be possible to have Ooloi's windows with Nord Light instead of Nord Dark?

Technically easy. Whether to offer it is a different question: Nord Dark may become part of Ooloi’s visual identity rather than a preference. Still undecided.

Offering Nord Light as an alternative to Nord Dark would be appreciated by me and others who have eyes that are not compatible with dark themes.

That’s an important aspect. I’ll keep it in mind.

What is the realistic date for a beta release?

Thank you for the interest. The honest answer is: I don’t know yet.

I follow Knuth’s approach here: done when it’s done, no public timelines. The infrastructure phase took longer than expected; the current phase may surprise me either way.

For context, the window shown in this post is four days old, so things _are_ moving. When there _is_ something concrete to announce, this blog will be the first place it appears: it functions both as a development log and a record of the thinking behind the work.

What is the percentage of original Igor code that you can use?

There is plenty of darkness in the world, to enter into the light can be very revealing. It’s fantastic to see an open window, I can sense the essence through that open window!

Great work and for your perseverance in this venture! Thank you.

Ant,

Zero. Igor Engraver was Common Lisp; Ooloi is Clojure. Different language, different architecture, different era. More detail here:

I thought the whole enterprise was more of a 'transcription' of Igor. A lot of work from scratch actually. In theory, would it not have been easier just to code a decent GUI to Lilypond to get to a good open source notation software?
