(1) I am working on a port of 9front to the pinephone smartphone.=20 Although it is still a long way to go I believe the project can be very=20 interesting for UI ideas and implementations. This would also fit tbe rio=20 alternatives idea. Let me quickly explain. Plan 9 has a unique user interface built from many components. We have=20 heavy use of three mouse buttons, many text-based interfaces (also=20 counting acme tags, for example), system-wide plumber support, only to=20 mention few of those. However, some of these aspects don't make much=20 sense on a touch device due to big thumbs and the nature of touchscreens. The idea for this would be designing an integrated, Plan 9-worthy=20 touchscreen rio replacement for mobile devices. Ideally it can coexist=20 with rio (i.e run inside rio windows and rio can run inside=20 "this-window-manager" windows) and is fully compatible with existing=20 graphical UI applications (using standard draw routines). Although the software can currently not be tested on the pinephone (I'm=20 still working on the kernel) there are some devices with rudimentary=20 touchscreen support (I have a working thinkpad twist with 9front) we can=20 use for testing, and some functionality can be tested inside scaled rio=20 windows on common Plan 9 systems. (2) Under similar circumstances (mobile device with touch input) another=20 project might be some kinda graphical (rc) shell interface. I have an=20 idea, and we also discussed ideas on the discord server. (3) A high-level filesystem interface for UI widgets. Many modern UI=20 layouts can be described as a hierarchy of containers. The UI filesystem=20 would start as an empty window, which is reflected by an empty=20 filesystem. The user could create widget containers (hbox, vbox) by=20 creating directories and files, as well as input boxes, buttons and more=20 by creating files. The hierarchy would directly reflect the drawn window.=20 The user can listen to files for button interaction and write text to=20 labels etc.. (4) A filesystem that filters a namespace, but the file contents and not=20 the namespace. The idea is to have a filesystem like exportfs, however, it doesn't just=20 represent the files as is, but applies user-defined filters to the=20 filenames/paths as well as the file contents. Imagine you have a namespace which contains markdown files that end with=20 .md. Using this overlay filesystem you can present the same namespace,=20 but convert the filenames using sed (from .md to .html) and when reading,=20 the file contents (from markdown syntax to html syntax). The filesystem would be very powerful for exposing plain text data as=20 html, encapsulating data into some predefined layout, and much more. It=20 could essentially make any plain text filesystem available as regular=20 web-friendly html files, convert troff source to postscript, convert plan=20 9 images to png, and much more. You can even present device files as json=20 for modern web applications. Caching file contents can improve performance and reduce load. (5) Ringfs. This is a very small project and also the least powerful as=20 far as I can say now. The general idea is that the filesystem presents the created files and=20 when reading a file the contents point to the next file in the "ring" in=20 alphabetical order. It's probably best explained using the following shell interaction: ; touch fileA fileB fileC ; cat fileA fileB ; cat fileB fileC ; cat fileC fileA The project is very small and probably too simple for a GSoC project. These are some ideas I thought about in the last months. Some are very=20 small and I can imagine mentoring these smaller projects if it's not to=20 hard. My time is rare (as for most of you I guess) and I never mentored=20 any programmer, so I guess I'd ask more experienced people now and then. Personally I like all of these ideas and would like to work on all of=20 them if I had enough time. sirjofri ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Td4449edc4863e16e-M7eef4= 9e9a147609a6fee4160 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
