Avestan keyboard layout

Keyboard Layout - Avestan

According to Wikipedia, Avestan (pronounced /əˈvɛstən/ [1]) is an Iranian language known only from its use as the language of Zoroastrian scripture, i.e. the Avesta, from which it derives its name. The language must also at some time have been a spoken language, but how long ago that was is unknown. Its status as a …

Ο Νίκος Μουτσανάς έφτιαξε δύο εναλλακτικές διατάξεις πληκτρολογίου που μπορεί να φανούν χρήσιμες σε όσους γράφουν συχνά σε διάφορες λατινικές (ευρωπαϊκές) διατάξεις πληκτρολογίου και θέλουν μια κοινή συγκεντρωτική διάταξη θέλουν μια ελληνική διάταξη που να επιτρέπει και αγγλικά με τη χρήση του AltGr (δηλαδή μια διάταξη για ελληνικά και αγγλικά) Είναι πιθανό κάποιες από τις …

The Keyboard Layout Editor

Update Dec 2010: Get the latest version of the Keyboard Layout Editor from https://github.com/simos/keyboardlayouteditor (this entry is a repost, the original was lost in a database mishap.) As part of the 2008 GSoC program, I worked on a Keyboard Layout Editor for the X.Org Foundation. The Keyboard Layout Editor (KLE) is an application that allows …

Layout editor keyboard

This is a screenshot of the keyboard for the layout editor. The keyboard is a widget which is composed of individual widgets of each key. I did not use glade-3 for the keyboard at this time. Although it is possible to create custom widgets in Python and install them in Glade, the current distributed packages …

Converting between XKB and XML

I completed the stage that takes keyboard layout files from XKB (X.Org) and converts them to XML documents, based on a keyboard layout Relax NG schema. Then, these XML documents can also be converted back to keyboard layout files. Here is an imaginary example of a keyboard layout file. // Keyboard layout for the Zzurope …

ANTLR grammar for XKB, and Relax NG schema (draft)

I completed the ANTLRv3 grammar for symbols/ configuration files of XKB. The grammar can parse and create the abstract syntax tree (AST) for all keyboard layouts in xkeyboard-config. ANTLRv3 helps you create parsers for domain specific languages (DSL), an example of which is the configuration files in XKB. Having the ANTLRv3 grammar for a configuration …

Looking into the symbol files

In the previous post, we talked about the ANTLR grammar that parses the XKB layout files. The grammar is available at http://code.google.com/p/keyboardlayouteditor/source/browse. I’ll rather push to the freedesktop repository once the project is completed. Now it’s too easy for me, just doing svn commit -m something. Below you can see the relevant layout files for …

Parsing XKB files with antlr

antlr (well, antlr3) is an amazing tool that replaces lex/flex, yacc/bison. One would use antlr3 if they want to deal with Domain-Specific Languages (DSL), an example of which are the text configuration files. In our case, we use antlr3 to parse some of the XKB configuration files, those found in /etc/X11/xkb/symbols/??. Our aim is to …

Testing the updated IM support in GTK+

In Improving input method support in GTK+-based apps, we talked about some work to update the list of compose sequences that GTK+ knows to the latest version that comes from Xorg. From 691 compose sequences, we now support over 5000. The patch has landed in GTK+ (trunk), and here are instructions for testing. If you …

Keyboard layout for combining diacritics

Typically, if you want to type characters with accents, such as á, ë, ś, you need to configure a suitable keyboard layout that includes compose sequences for those characters. The produced characters are what we call as precomposed characters; which were included in the early stages of Unicode. Nowdays, the idea is that you do …
