The I/O stream itself would - serve as a function to read or write one character. - -* If a file you can't write is in a directory you can write, - make sure it works to modify and save this file. - -* Make dired's commands handle correctly the case where - ls has listed several subdirectories' contents. - It needs to be able to tell which directory each file - is really in, by searching backward for the line - which identifies the start of a directory. - -* Add more dired commands, such as sorting (use the - sort utility through call-process-region). - -* Make display.c record inverse-video-ness on - a character by character basis. Then make non-full-screen-width - mode lines inverse video, and display the marked location in - inverse video. - -* VMS code to list a file directory. Make dired work. - -Long range: - - Ideas for extending GNU Emacs to deal with arbitrary character sets. - -I would like GNU Emacs to be extended to handle all the world's alphabets -and word signs. I don't expect to have time to do such a thing in the next -few years, so here are my ideas on the best way to do it. - -* Each graphic is represented by a sequence of ordinary 8-bit characters. - -* All the characters that make up such a sequence have codes >= 0200. - -* The first character of such a sequence is between 0200 and 0237. - -* The remaining characters of such a sequence are all 0240 or higher. - -* The first character of the sequence determines the number of characters -in the sequence. Thus, 0200...0207 could start two-character sequences, -0210...0227 could start three-character sequences, and 0230 could start -four-character sequences. (Codes 0231...0237 would be reserved.) - -* Several common alphabets, and some mathematical symbols, would get -two-character sequences. (Probably Greek, Russian, Hebrew(?), Arabic(?), -Korean, and Japanese kana). The remaining alphabets, and some versions of -Chinese, would get three-character sequences. Other sets of Chinese -characters would get four-character sequences. - -Each country that uses Chinese characters has its own standard character -set, and it is not easy to correlate them to avoid overlap. So there may -need to be several sets of Chinese characters. That is why they need so -much code space. - -True support for Hebrew and Arabic requires dealing with the problem of -writing direction for mixed text; I don't know what to do for that. - -* The functions that use syntax table would determine the -syntax of a sequence from its first character. - -* Functions in indent.c for computing widths and columns would -determine the width of a sequence from its first character. -So would display routines. - -* Only a few other editing routines would need any change. In -particular, searching and regexp matching might not need any change. - -* Most of the work required would be in redisplay. The only case that -needs to be supported is with X windows, since ordinary terminals -can't display all these characters anyway. - -* There might need to be code to translate files from this format -to whatever format is typically stored on disk. - - -I would be very unhappy with half-measures, such as support for -Japanese only. - |
