I am leaving tomorrow for a one-month vacation to Spain. I'll be returning on August 1st. I will occasionally be checking mail at ben_wing(a)hotmail.com, but not at this address. If you have something that isn't urgent, go ahead and send it to this address [either ben(a)666.com or ben(a)xemacs.org] and i'll respond when i return. meanwhile, i've checked in two workspaces to cvs. i'd appreciate it if people take a look and fix any problems encountered. [i've checkpointed the workspaces at their current state, so i'll be able to review any changes made.] NOTE: The contents of this message are in README.ben-mule-21-5 at the top of the ben-mule-21-5 workspace. the two workspaces are: ------------------------------------------------------------------ -- ben-mule-21-5 this contains all the mule work i've been doing. this includes mostly work done to get mule working under ms windows, but in the process i've [of course] fixed a whole lot of other things as well, mostly mule issues. the specifics: - it compiles and runs under windows and should basically work. the stuff remaining to do is (a) improved unicode support (see below) and (b) smarter handling of keyboard layouts. in particular, it should (1) set the right keyboard layout when you change your language environment; (2) optionally (a user var) set the appropriate keyboard layout as you move the cursor into text in a particular language. - i added a bunch of code to better support OS locales. it tries to notice your locale at startup and set the language environment accordingly (this more or less works), and call setlocale() and set LANG when you change the language environment (may or may not work). - major rewriting of file-coding. it's mostly abstracted into coding systems that are defined by methods (similar to devices and specifiers), with the ultimate aim being to allow non-i18n coding systems such as gzip. there is a "chain" coding system that allows multiple coding systems to be chained together. (it doesn't yet have the concept that either end of a coding system can be bytes or chars; this needs to be added.) - unicode support. very raw. a few days ago i wrote a complete and efficient implementation of unicode translation. it should be very fast, and fairly memory-efficient in its tables. it allows for charset priority lists, which should be language-environment specific (but i haven't yet written the glue code). it works in preliminary testing, but obviously needs more testing and work. as of yet there is no translation data added for the standard charsets. the tables are in etc/unicode, and all we need is a bit of glue code to process them. see etc/unicode/README for the interface to implement. - support for unicode in windows is partly there. this will work even on windows 95. the basic model is implemented but it needs finishing up. - there is a preliminary implementation of windows ime support courtesy of ikeyama. - if you want to get cyrillic working under windows (it appears to "work" but the wrong chars currently appear), the best way is to add unicode support for iso-8859-5 and use it in redisplay-msw.c. we are already passing unicode codepoints to the text-draw routine (ExtTextOutW). (ExtTextOutW and GetTextExtentPoint32W are implemented on both 95 and NT.) - i fixed the iso2022 handling so it will correctly read in files containing unknown charsets, creating a "temporary" charset which can later be overwritten by the real charset when it's defined. this allows iso2022 elisp files with literals in strange languages to compile correctly under mule. i also added a hack that will correctly read in and write out the emacs-specific "composition" escape sequences, i.e. ESC 0 through ESC 4. this means that my workspace correctly compiles the new file devanagari.el that i added (see below). - i copied the remaining language-specific files from fsf. i made some minor changes in certain cases but for the most part the stuff was just copied and may not work. - i fixed post-read-conversion in coding systems to follow fsf conventions. (i also support our convention, for the moment. a kludge, of course.) - make-coding-system accepts (but ignores) the additional properties present in the fsf version, for compatibility. ------------------------------------------------------------------- -- ben-separate-stderr-improved-error-trapping this is an old workspace, very close to being done, containing - subprocess stderr output can be read separately; needed to fully implement call-process with asynch. subprocesses. - huge improvements to the internal error-trapping routines (i.e. the routines that call Lisp code and trap errors); Lisp code can now be called from within redisplay. - cleanup and simplification of C-g handling; some things work now that never used to. - see the ChangeLogs in the workspace. -- ben I'm sometimes slow in getting around to reading my mail, so if you want to reach me faster, call 520-661-6661.
