Layout variants +can describe common differences that are not necessarily printed on the keys. +(e.g. a phonetic version of Cyrillic). + +The names of the files are referenced throughout the XKB rules, and may be +exposed in the X server configuration and in user configuration tools. +The filenames use the following convention: + +Country layouts: + + Keyboard layouts for a country must use the 2-letter code from the + ISO-3166 standard. + +Language layouts: + + Keyboard layouts for a language must use the 3-letter code from the + ISO-639 standard. + +Script layouts: + + Keyboard layouts for a script must use the 4-letter code from the + ISO-15924 standard. + +Other: + + Keyboard layouts that do not fit in the above model and directories + must use a filename between 5 and 8 characters. + +The ISO codes can be found at the following addressed: + +Country layouts: http://www.iso.org/iso/en/prods-services/iso3166ma/02iso-3166-code-lists/iso_3166-1_decoding_table.html +Language layouts: http://www.loc.gov/standards/iso639-2/langcodes.html +Script layouts: http://www.unicode.org/iso15924/iso15924-codes.html + +The description in the directory file base.xml.in should match the group names +in the symbols file. + +If the layout is country-based, this has to be the full +name of the country. It is highly not recommended to use the forms +"Republic of XXX" or "XXX Republic" - the form "XXX" should be used instead. +The only exception is "United Kingdom". + +If the layout is language-based, this has to be the name of the language. + +Within single symbols file, all the variants should have the same group name +(implemented using the "include" directive wherever possible). |
