Yep, Calligra Active was even the starting point when I begun that. I
switched away when going full threaded cause that was requiring a
complete different architecture and design. In Coffice all of Calligra
runs in another thread then the UI/QML. That means all operations are
asynchronous in Coffice unlike in Active and Calligra will never be able
to block the UI. Also I bundle all plugins into one plugin, all filters
into one filter and delay loading in Coffice plus don't use KDE
plugin-lookup (aka sycoca) cause sycoca isn't present, I rewrote the kde
factory/plugin/kpart stuff, etc. pp.
Since all that happened Qt5 progressed and meanwhile (means not so long
ago) work on scenegraph-based QTextDocument/QTextEdit landed. So, for
Qt5 there may an option (with very likely lots of additional work needed
for our use-cases) to solve the no-go all-in-one-thread problem at
another level. On the other hand there would still be work needed to get
potential long-blocking operations like loading threaded which is all
solved in Coffice as of today already.... Well, we will see.

<pre wrap="">Aloha,
so you may have noticed that I did land last few weeks work in the
Coffice-branch. I am giving here a short status-update on the work done and
the work I plan to do towards releasing the first release of the Calligra
Mini successor of Coffice. Note that this is only my personal roadmap and
subject to change anytime. So, if you think there is something missing,
something not so important, etc. please just raise voice and I can shift.
=== Work published ===
Current version (as published in Google Play) is 1.5. 1.5 is the first
release I not see as "alpha release" but as "beta release". Its stable,
fast, loads and displays ODT/DOC/DOCX. Its "good enough to be usable" but
there is still plenty to do from my pov.
=== Work landed ===
What I did withint last ~2 months is to focus on 2 areas:
1) SailfishOS version.
So far Coffice builds and runs on Linux desktop and Android. SailfishOS is
the second mobile SDK targetted (by me). It compiles and runs but doesn't
display, etc. yet. Remaining work is on the UI (Silicia components) only.
2) Sheets integration.
Calligra Sheets compiles now using the fake-lib on desktop, Android and
SailfishOS. It compiles and links but not more. Means missing here is the
UI-integration.
=== Work to do ===
What I would like to do before releasing a first Calligra Mini version is
to finish Sheets and make loading and displaying a ODS file proper working.
That's the only thing I have atm on my table. Estimate would be in the
range of <3 months depending on the amount of spare time that is left.
=== Feedback ===
If there is anything you think that is missing from current version 1.5
(as available in Google Play), that needs to be changed/added/removed
before a Calligra Mini x.y release then please let me know now. Thanks in
advance :)
