HowTo: Avoid packages like TPU
by T. V. Raman-2

Rate this Message:
With loaddefs.el in Emacs 22, rarely used packages like tpu end up showing up in the default obarray operated upon by mapatoms. Is there a way to avoid this? I use reflection via mapatoms to find interactive commands that need to be speech-enabled in Emacspeak, and one unfortunate consequence is the following: 0) mapatoms finds commands like "set cursor free" from tpu-extras 1) In using reflection, it ends up loading tpu-extras.el (even though I have no intention of using tpu) 2) Worse, tpu-extras is evil -- it redefines things like newline 3) And even worse, tpu-current-line (used by the redefined newline) raises errors at times when called from display-warning. In the minimum it would be nice if optional packages that redefine core functionality such as command `newline' didn't get accidentally pulled in. In GNU Emacs 22.1.50.11 (i686-pc-linux-gnu, GTK+ Version 2.8.20) of 2007-08-04 on labrador configured using `configure '--prefix=/usr/local' '--with-toolkit=gtk'' Important settings: value of $LC_ALL: nil value of $LC_COLLATE: nil value of $LC_CTYPE: nil value of $LC_MESSAGES: nil value of $LC_MONETARY: nil value of $LC_NUMERIC: nil value of $LC_TIME: nil value of $LANG: en_US.UTF-8 locale-coding-system: utf-8 default-enable-multibyte-characters: nil Major mode: Shell Minor modes in effect: jabber-activity-mode: t erc-menu-mode: t erc-autojoin-mode: t erc-ring-mode: t erc-pcomplete-mode: t erc-track-mode: t erc-match-mode: t erc-button-mode: t erc-fill-mode: t erc-stamp-mode: t erc-netsplit-mode: t dired-omit-mode: t dynamic-completion-mode: t erc-irccontrols-mode: t erc-noncommands-mode: t erc-readonly-mode: t shell-dirtrack-mode: t display-time-mode: t desktop-save-mode: t auto-insert-mode: t encoded-kbd-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t unify-8859-on-encoding-mode: t utf-translate-cjk-mode: t auto-compression-mode: t Recent input: SPC a t t a c h i n g SPC a SPC s t a c k - t r a c e ; SPC t h o u g h SPC I SPC n o w SPC h a v e SPC a SPC f i x SPC f o r SPC e m a c s p e a k , SPC i t SPC w o u l d SPC b e SPC ESC DEL p r o b a b l y SPC b e SPC u s e f u l SPC t o SPC f i x SPC t h e DEL DEL DEL SPC t h e SPC s i g n a l SPC t h a t SPC i s SPC b e i n g SPC r a i s e d SPC f o DEL r o m SPC a SPC c o d e SPC h y g e n e SPC p o i n t SPC o f SPC v i e w .

With loaddefs.el in Emacs 22, rarely used packages
like tpu end up showing up in the default obarray operated upon by mapatoms. Is there a way to avoid this? The only easy way is to delete the autoloads. But why do that? There are not very many of them. 0) mapatoms finds commands like "set cursor free" from tpu-extras 1) In using reflection, it ends up loading tpu-extras.el (even though I have no intention of using tpu) What is "reflection"? Perhaps we should put the tpu-extras.el autoloads into tpu-edt.el instead of into loaddefs.el. I think that only tpu users would want to call those entry points. Stefan, you know how to do that. Would you please do that? _______________________________________________ emacs-pretest-bug mailing list emacs-pretest-bug@... http://lists.gnu.org/mailman/listinfo/emacs-pretest-bug |

That is ugly, the same way advice is ugly, but the change to the behavior of `newline' is harmless enough. 3) And even worse, tpu-current-line (used by the redefined newline) raises errors at times when called from display-warning. How does it happen that tpu-current-line is not loaded? tpu-extras starts with (require 'tpu-edt). It looks like the redefinition of `newline' is done as part of a scheme to implement scroll margins. Emacs nowadays has scroll margins as a built-in feature. So I think all that code could be replaced by a few variable aliases. Would someone like to do that, and ack? _______________________________________________ emacs-pretest-bug mailing list emacs-pretest-bug@... http://lists.gnu.org/mailman/listinfo/emacs-pretest-bug |

All such bugs should be reported via M-x report-emacs-bug. By principle, loading an elisp package should not have any adverse affect (it should basically have no effect other than the expected ones: define additional functions and variables and maybe a few more). > 3) And even worse, tpu-current-line (used by the redefined newline) > raises errors at times when called from display-warning. I do not understand this one. Can you expand on it?

Should be "fixed" now (it uses advice and only activates it when needed). Stefan _______________________________________________ emacs-pretest-bug mailing list emacs-pretest-bug@... http://lists.gnu.org/mailman/listinfo/emacs-pretest-bug |

It's done here, I'm just waiting for syncs and a few other things before committing it.

There is perhaps something I dont quite understand about the Emacs CVS repos. I'm using: :pserver:anoncvs@...:/sources/emacs and building this results in a version that calls itself 22.1.50.x -- is that a "branch" or a "trunk"? Also, is there something newer called Emacs 23 in the CVS repository that I could be using? emacs >>>>> "Stefan" == Stefan Monnier <monnier@...> writes: >> Just did a CVS update, and I still see the old version of >> tpu-extras in the sources i.e. it defines newline.

I think I finally got this right (I hope) someone please confirm -- (I check (functionp (indirect-function sym)) before I do anything like calling interactive-form -- incidentally calling interactive-form was also automatically loading files. While debugging this, I also noticed that there is a problem with cal-bahai.el (not a module I need to load anymore given that I dont load anything unecessarily)-- but the problem if users of cal-bahai care is that functions like insert-yearly-diary-entry for that module have some bizarre naming problem. >>>>> "tvr" == T V Raman <raman@...> writes: tvr> But here is the problem though: How do I find out after tvr> having called (functionp sym) and getting back T if the tvr> function is already loaded?
