Hi, 3.33.3 is a beautiful palindrome version number, reading it from left to right or right to left doesn't make a difference.
Not so much with Arabic, Hebrew, Persian, Syriac, Urdu etc. scripts. They need to go from right to left, and thus they often show up backwards in terminals with their traditionally inherent left to right characteristics. I'm thrilled to announce that GNOME Terminal 3.33.3 (well, in fact VTE 0.57.3) introduces support for right to left (RTL) and bidirectional (BiDi) text. The work involved understanding the conflicting requirements, examinimg the behavior of other terminals, studying an almost 30 year old document on this topic; and based on these coming up with a technical proposal  that resolves the conflicts and addresses all the requirements, is reasonably simple and reasonably backwards compatible, and builds on the existing Unicode Bidirectional Algorithm and BiDi best practices. Needless to say, this design also had to be implemented. GNOME Terminal's new default is to shuffle the characters for the display according to the BiDi algorithm. This fixes the behavior of simple utilities where RTL text previously appeared in reverse order. There are applications that require the terminal not to shuffle the characters. Emacs's BiDi-aware text editing is one example, as it shuffles the characters itself and sends them to the terminal in the desired display order. This behavior of the terminal can be set with: printf "\e[8l" and performing BiDi by the terminal can be re-enabled with: printf "\e[8h" Other escape sequences are also available, e.g. to autodetect the text direction, or switch to RTL paragraph direction. Consult vte/perf/bidi.sh or the specification for details. The current milestone is an extremely important one, but isn't the end of the road. There's one notable technical issue with the specification and the current implementation: BiDi control characters at the beginning of a logical string are lost. I'm planning to address this in the next development cycle. The current work adds BiDi to this platform, but what the user cares about is the entire ecosystem, the overall user experience. To provide the best experience, applications will need to use this platform wisely, e.g. automatically turn off BiDi if that's what they need (the user shouldn't need to issue those aforementioned commands manually). It'll probably take years of ongoing improvements to get the most out of the terminal's new features. Until then, such inconveniences as having to manually set the desired mode remain, but at least now you can set the desired mode and get nice BiDi experience, which is a giant step forward. Enjoy it! cheers, egmont  https://terminal-wg.pages.freedesktop.org/bidi/ _______________________________________________ gnome-announce-list mailing list email@example.com https://mail.gnome.org/mailman/listinfo/gnome-announce-list
