EXTERNAL_LIST_LOOP_2 interface and semantics changed - propose reversion 23 years, 9 months

Martin Buchholz

EXTERNAL_LIST_LOOP_2(elt, list) used to require that the user declare elt and list. After Ben's recent changes to the LIST_LOOP macros, the macro itself declares elt. I think this is a mistake and propose reversion. This is a similar issue to the question of how long the scope of an identifier declared in a `for' initializer lasts in C++ or C99. Some users of EXTERNAL_LIST_LOOP_2 may want to use the value of elt after the loop has exited. And there are other reasons why the user may want a different scope for elt. One could provide two versions of EXTERNAL_LIST_LOOP_*, but I think it is clearly not worth the confusion. The saving of one declaration Lisp_Object elt; is not worth the loss of flexibility and increase in magicality. Ohhhhhh, I see now Ben *has* created _NO_DECLARE versions of these macros. I think this is very subtle and confusing. EXTERNAL_LIST_LOOP_2_NO_DECLARE declares *some* of the variables, but not all. The name suggests to me "No Declarations At All", and I was suprised to discover it does some of them *and* still requires the added braces. I think this is too subtle a distinction and propose reversion to the old interface, and removal of all the _NO_DECLARE macros. With my previous implementation of these macros, it was very simple for the user to know which variables had to be declared - all the variables mentioned in the macro call had to be declared. This makes the use of these macros somewhat less magical. There's still the magic of having to provide a { } block around the call, but that seems unavoidable, and the compiler error in case of a mistake means that no subtle bugs will be introduced. This issue is similar in spirit to the TO_EXTERNAL_FORMAT debate. I want to avoid a proliferation of APIs that cause confusion for the maintainers. Both of these changes have confused *me*, the original implementor - I now feel less sure when using these macros. Martin

Status of http://sourceforge.net/projects/xemacs/ 23 years, 9 months

Adrian Aichner

Hello All! This is intended to be a bootstrapper for anybody interested in getting started on the sourceforge half of XEmacs development. Q: Has XEmacs development moved to sourceforge? A: No. Currently there is only one CVS module on sourceforge, namely xemacsweb. This is the content of xemacweb＠www.xemacs.org:~/genpage which prduces most of the static content of xemacweb＠www.xemacs.org:~/docs. Mailing list and their archives, for one, have not been moved to sourceforge. Q: Which is the offical XEmacs Website? A: For a transitional period of at least two weeks it is good old http://www.xemacs.org. To visit the new site (and receive bonus points for testing) go to http://xemacs.sourceforge.net/, either directly, or via "Project Homepage" from https://sourceforge.net/projects/xemacs/. Thereafter, if all goes well, http://xemacs.sourceforge.net/ will answer for http://www.xemacs.org if someone puts in the work to make it so (http://sfdocs.sourceforge.net/sfdocs/display_topic.php?topicid=33). Q: So what's so exciting about the new site? A: It is fully CVS-controlled, all HTML documents are batch-validated daily using XEmacs/PSGML by xemacsweb/Makefile according to their individual DTD. Alltogether there are <10 HTML errors left between all .html files on the XEmacs site there! Q: When can I contribute to XEmacs website content again? A: Now. Get yourself a sourceforge account via https://sourceforge.net/account/register.php and contact one of your friendly XEmacs admins to become a developer, using https://sourceforge.net/project/memberlist.php?group_id=11. Q: How do I make changes to the XEmacs CVS repository on sourceforge? A: Follow instructions in https://sourceforge.net/cvs/?group_id=11 to checkout (20MB after running make) and commit the sources via CVS. Q: How can I keep track of changes being made to the repository? A: Subscribe yourself to xemacs-checkins(a)lists.sourceforge.net[1] at http://lists.sourceforge.net/mailman/listinfo/xemacs-checkins. We may even subscribe xemacs-cvs(a)xemacs.org to the list, if somebody can send back a confirmation reply from there. The mailing list archive at http://www.geocrawler.com/lists/3/SourceForge/5231/0/4114662/ is actually updated quite switfy (> 30 minutes?). Q: How do I inspect the state of the actual files behind http://xemacs.sourceforge.net/? A: Read http://sfdocs.sourceforge.net/sfdocs/display_topic.php?topicid=8 for reference, although steps 1 .. 7 are already done. Webpage contents are physically rooted at shell.sourceforge.net:/home/groups/xemacs/htdocs where htdocs is currently a symlink to xemacsweb. Q: How do these pages get updated? A: They are currently being updated a personal crontab entry of mine (temporarily, until Martin hand-holds me through direct updates from cvs commits). Here's[2] that crontab entry (as others may not have the privelege to look at it with "crontab -u adriana -l", which doesn't work even for me). This gets mailed to xemacs-checkins(a)lists.sourceforge.net for now. xemacs-webmaint(a)xemacs.org may be a better destination when I have fixed ALL validation errors (there are still FIVE!). Q: What editor can I use on shell.sourceforge.net? A: ed, when you use ssh. :-) I have installed a pretty well-featured XEmacs-21.1.11 under shell.sourceforge.net:/home/groups/xemacs/tools/xemacs/bin for all of us to use. See ~adriana/.profile for my setup. I also had to get a decent tty for Windows NT for XEmacs to run, be it -nw even. I installed http://www.chiark.greenend.org.uk/~sgtatham/putty/latest/putty.exe and am quite happy with it. Q: Can I upload big files to some kind of /pub on sourceforge? A: Yes, developers can copy files to <user>＠shell1.sourceforge.net:/home/groups/ftp/pub/xeemacs using scp1. Anyone can download from this URL: ftp://xemacs.sourceforge.net/pub/xemacs/[3] Q: How much did Adrian sleep lately? A: Permission denied. I hope this will be helpful to others. We should probably start assigning jobs between us to further development on sourceforge. A big task would be conversion of mailing list interfaces and archives, although I am not sure we want to move them away from xemacs.org. Making all URLs in xemacsweb relative is on our collective to-do list. genpage should come to our aid here. More on that later. Any comments? Adrian Footnotes: [1] Contrary to http://sfdocs.sourceforge.net/sfdocs/display_topic.php?topicid=52, it is not possible to create a list called xemacs-cvs(a)lists.sourceforge.net because cvs is shorter than the minumum 4 characters.
