From 6cbb40bb82ae2af1adaea996a385ab953f62de3f Mon Sep 17 00:00:00 2001 From: tsuchiya Date: Tue, 29 Oct 2002 16:28:56 +0000 Subject: [PATCH] Clean up codes. (nnshimbun-buffer, nnshimbun-current-directory) (nnshimbun-current-group, nnshimbun-server-directory): Removed. (nnshimbun-current-server, nnshimbun-server-directory) (nnshimbun-current-group, nnshimbun-current-directory): New macros. (nnshimbun-backlog, nnshimbun-find-parameter): Use `nnshimbun-current-server'. (nnshimbun-possibly-change-group, nnshimbun-open-server): Reimplemented. (nnshimbun-close-server): Do not kill `nnshimbun-buffer'. (nnshimbun-request-article-1, nnshimbun-request-list): Use `erase-buffer' instead of `delete-region'. (nnshimbun-request-article): Use `nnshimbun-current-group'. (nnshimbun-request-group): Remove redundant checks. (nnshimbun-request-scan): Check arguments strictly. (nnshimbun-retrieve-headers, nnshimbun-retrieve-headers-with-nov): Reimplemented. (nnshimbun-generate-nov-database, nnshimbun-search-id) (nnshimbun-write-nov, nnshimbun-request-expire-articles): Simplified. (nnshimbun-nov-buffer-name, nnshimbun-nov-file-name): Make the first argument optional. (nnshimbun-open-nov): Bind variables to set coding systems for path names. --- ChangeLog | 27 +++ lisp/nnshimbun.el | 527 +++++++++++++++++++++++++---------------------------- 2 files changed, 272 insertions(+), 282 deletions(-) diff --git a/ChangeLog b/ChangeLog index 99ae493..ebf343c 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,30 @@ +2002-10-30 TSUCHIYA Masatoshi + + * lisp/nnshimbun.el: Clean up codes. + (nnshimbun-buffer, nnshimbun-current-directory) + (nnshimbun-current-group, nnshimbun-server-directory): Removed. + (nnshimbun-current-server, nnshimbun-server-directory) + (nnshimbun-current-group, nnshimbun-current-directory): New macros. + (nnshimbun-backlog, nnshimbun-find-parameter): Use + `nnshimbun-current-server'. + (nnshimbun-possibly-change-group, nnshimbun-open-server): + Reimplemented. + (nnshimbun-close-server): Do not kill `nnshimbun-buffer'. + (nnshimbun-request-article-1, nnshimbun-request-list): Use + `erase-buffer' instead of `delete-region'. + (nnshimbun-request-article): Use `nnshimbun-current-group'. + (nnshimbun-request-group): Remove redundant checks. + (nnshimbun-request-scan): Check arguments strictly. + (nnshimbun-retrieve-headers, nnshimbun-retrieve-headers-with-nov): + Reimplemented. + (nnshimbun-generate-nov-database, nnshimbun-search-id) + (nnshimbun-write-nov, nnshimbun-request-expire-articles): + Simplified. + (nnshimbun-nov-buffer-name, nnshimbun-nov-file-name): Make the + first argument optional. + (nnshimbun-open-nov): Bind variables to set coding systems for + path names. + 2002-10-29 Katsumi Yamaoka * lisp/gnus-vers.el (gnus-revision-number): Increment to 05. diff --git a/lisp/nnshimbun.el b/lisp/nnshimbun.el index 8135315..59b3fa6 100644 --- a/lisp/nnshimbun.el +++ b/lisp/nnshimbun.el @@ -32,7 +32,7 @@ ;; Visit the following pages for more information. ;; ;; http://emacs-w3m.namazu.org/ -;; http://ei5nazha.yz.yamagata-u.ac.jp/~aito/w3m/ +;; http://w3m.sourceforge.net/ ;; If you would like to use this module in Gnus (not T-gnus), put this ;; file into the lisp/ directory in the Gnus source tree and run `make @@ -44,13 +44,11 @@ ;;; Definitions: (eval-when-compile (require 'cl)) +(require 'nnoo) (require 'nnheader) (require 'nnmail) -(require 'nnoo) -(require 'gnus) (require 'gnus-bcklg) (require 'shimbun) -(require 'message) ;; Customize variables @@ -165,8 +163,8 @@ article are encapsulated. `Expire wait' is similar to the generic group parameter `expiry-wait', but it has a preference.") -(defcustom nnshimbun-keep-unparsable-dated-articles t - "*If non-nil, nnshimbun will never delete articles whose NOV date is unparsable." +(defcustom nnshimbun-keep-unparsable-dated-articles t "\ +*If non-nil, nnshimbun will never delete articles whose NOV date is unparsable." :group 'nnshimbun :type 'boolean) @@ -200,26 +198,35 @@ parameter `encapsulate-images' for each nnshimbun group.") just a default value for all the nnshimbun groups.
