Re: tar-mode and crypt revisted 25 years, 5 months

Neal D. Becker

Actually, it's stranger than that. When I visit a .tar.gz, it sometimes works correctly and sometimes doesn't. It seems to depend on the loading of other packages - but I haven't isolated it further.

JDE & EFS... 25 years, 5 months

Blob, Dave

Hi, I downloaded 21.1.3 and the sumo tarball and had problems editing remote java files. It looks to be a problem with JDE - specifically where it tries to find the project file (jde-find-project-file or jde-root-dir). I think adding successive ../'s is never giving a final root directory, but this is just a guess. In the meantime, since I don't really need it, I disabled jde. I don't need any resolution - I just thought I'd point it out. Thanks, Dave

Okay, here's my $0.02. In order for threading to work with emacs-lisp the following things need to happen. (We're talking relatively long term here, hence the word roadmap.) o The OS First off, the OS itself needs to "support" threads. Most industrial strength OSes do so. Examples, DG/UX, HP/UX, AIX, Linux, Windoze, Sun. o [x]emacs [x]emacs would need to use a threaded library in order to support multiple threads of execution within the same process. gtk/glib would be _one_ solution. Its used extensively in gnome and mozilla. xemacs code would need to be made mt-safe by mutex-locking out critical sections of the code. gtk/glib could provide a new widget set to replace existing ones, but that's another debate. o emacs-lisp the base emacs-lisp would need to provide extended lisp functionality to interface with the low-level threads library. This would probably be a package that provides mutex o emacs-lisp applications Applications like gnus, w3 which can potentially do multiple asynchronous fetches in the background would, probably benefit from an mt emacs-lisp. Issues like how many threads (eg. 1 per newsgroup?) synchronization, mutual exclusion etc would probably be counter-balanced by improvement in performance and functionality. A context switch between two threads in a single process is considerably cheaper than a context switch between two processes. Also, all data except for stack and registers are shared between threads. This makes threading interesting for such apps. _LISP_ code wouldn't magically become mt-safe, it would need to be modified to make it so. One would, of course, have the option to use only a single thread of execution, so existing apps should work with even with mt emacs-lisp. > Do your homework before > spitting such nonsense damnit. Now now, there's no need for foul language. Go stand in the corner.

Guile uses a user space thread library that doesn't require OS threads. It only works on systems for which the assembler part has been written. It does stack-switching.

A `long-description' field would be nice, with a paragraph or more describing the package. I want to try and auto-generate the debian control file information from the package-info stuff. We use a description field, with one ~65 char line then a paragraph or so... You can read about it here: <URL:http://bittersweet.sysc.pdx.edu/doc/packaging-manual/packaging.html/c...> I have begun to write a few of them, and can send patches... but I am not satisfied with it the way I've got it now. I just added a `long-description' key and a one-long-line inside quotes. But the Debian descriptions can be several paragraphs, and it is often useful to have them contain bulletted lists and suchlike. We can't just use HTML since W3 is unbundled, right? Any Ideas? (I need to have a look at what other things I might need for the autogen of control files too... I'll spend a little time on that today.)

But they are themselves much different visually than the tabs that were used in the screenshot, and oriented differently. :) For the typical 'property sheet' type of widgets that andy is using, a border around them to show the area of control of the tab widget is normal and desired. If you do not, then the tab widget is really no different than a row of buttons placed on top of an arbitrary screen area. Now, if there was some way to use the smaller, triangular, bottom-oriented tab widgets, then I would agree that the extra border space is not needed _as much_. I'd still like to be able to see it as an option though. >From a gut reaction to thee screenshot, I'd say cool concept but no way in #%!＠! I'd use it on a daily basis. I would hope you could turn it off. I typically have so many buffers open that it would quickly get pretty nasty with the large tabs. Using the smaller ones typically seen in spreadsheets, etc, would be better, but could still get pretty cluttered. > Anyone remember the text base DOS IDE's that did MDI in text mode, > wasting a character on every side of the text window, so that you > actaully had a 50x10 window to edit in? Well, this isn't text mode though. It would only take a few pixels. And doesn't everyone run in 32bit 1600x1200 ? :) -bp

I guess if someone wanted to research it and learn how it might be done, Guile Scheme might be a good place to look. Certainly there are other schemes and lisps with threading... guile, rscheme, ecolisp, scheme48 I'm a few years away from that study, I've found. I tried... and am actually on the track, but it's a tall pile of books.
