They found essential problem with Emacs 20.3 are: + + - Emacs 20.3 separates string-type to unibyte-string and + multibyte-string. Emacs 20.3 has enough APIs to treat them. + + - Buffer has mode about interpretation of contents. Each mode is + designed to save semantics as characters. Namely buffer contains + unibyte-characters or multibyte-characters. One buffer can not + contain both representations. + + - {decode|encode}-coding-{region|string} run in byte world. So it + is not harmonized with other API. + + - It seems easy to write code in one mode or one world + (unibyte-string or multibyte-string). However it seems not easy + to write inter-mode program, such as SEMI. + + - Byte <-> byte conversion, such as base64, quoted-printable, must + be run only with unibyte-mode. + + - Byte <-> character conversion, such as + {decode|encode}-coding-region, should not be defined in single + buffer. Instead of them, decoder should read from unibyte buffer + and output to multibyte buffer. Similarly, encoder should read + from multibyte buffer and output to unibyte buffer. + `insert-buffer-substring' like API may be suitable. Anyway Emacs + introduces multiple representations, so it should be redesigned + based on multiple representation world model. + + Anyway FLIM should introduce new APIs based on inter-representation +world model. Conventional APIs should be implemented based on new +APIs. + + SEMI should abolish filter model and introduce new methods to +display inline data. These methods should use new FLIM APIs based on +inter-representation world model. + * MIME-Edit -- 1.7.10.4
