From: Stefan Monnier Date: Thu, 20 Jun 2002 17:40:38 +0000 (+0000) Subject: * progmodes/ada-mode.el: Update copyright notice. X-Git-Tag: ttn-vms-21-2-B4~14522 X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=80d50f8814552e2e773416336579c308680d183b;p=emacs.git * progmodes/ada-mode.el: Update copyright notice. Synchronize with GNAT release 3.15a1. Do not attempt to load ada-support, which is only for compatibility with older Emacs versions, and is not needed for Emacs 21. (ada-continuation-indent): New variable. New contextual menu: "List local reference", faster than "List References". (ada-mode): New alignment rules provided by S. Leake. (ada-mode): Add support for which-function-mode. Fix various calls to count-lines, that didn't work correctly when the buffer was narrowed. (ada-get-current-indent): Fix indentation of named parameter lists and nested boolean expressions. (ada-indent-on-previous-lines): Fix indentation of labels. (ada-search-prev-end-stmt): Fix searching of the previous end-statement, specially with regards to nested subprograms. (comment-region advice): Initially disabled, for better compatibility with other modes. (ada-fill-comment-paragraph): Fixed (no longer worked with Emacs 21). * progmodes/ada-xref.el: Update copyright notice. (ada-xref-create-ali): The default is now not to create automatically the ALI files by compiling the unit, since this isn't always reliable and requires an up-to-date project file. (ada-prj-default-comp-cmd): No longer use gcc directly to compile a file, but use gnatmake instead, since this gives access to the GNAT project files. (ada-xref-search-with-egrep): New variable, suggested by P. Waroquiers. (ada-load-project-hook): New variable, for support of GNAT project files. (ada-update-project-menu): Fix the detection of the project file name. (ada-add-keymap): Change key binding for ada-find-file, that conflicted with another binding in ada-mode.el. (ada-add-menu): New menu "List Local References", to list the reference to the entity only in the current file, instead of looking in the whole project. Much faster. (ada-find-references): New parameters arg and local-only. (ada-find-any-references): New parameters local-only and append. (ada-goto-declaration): Fix handling of predefined entities in xref. (ada-get-all-references): Updated to the new xref format in GNAT 3.15, still compatible with GNAT 3.14 of course. Fix various calls to count-lines, that didn't work correctly when the buffer was narrowed. --- diff --git a/lisp/progmodes/ada-mode.el b/lisp/progmodes/ada-mode.el index 62c70da0c92..3e4d5baa9ba 100644 --- a/lisp/progmodes/ada-mode.el +++ b/lisp/progmodes/ada-mode.el @@ -1,13 +1,13 @@ ;;; ada-mode.el --- major-mode for editing Ada sources -;; Copyright (C) 1994, 95, 97, 98, 99, 2000, 2001 +;; Copyright (C) 1994, 95, 97, 98, 99, 2000, 2001, 2002 ;; Free Software Foundation, Inc. ;; Author: Rolf Ebert ;; Markus Heritsch ;; Emmanuel Briot ;; Maintainer: Emmanuel Briot -;; Ada Core Technologies's version: $Revision: 1.49 $ +;; Ada Core Technologies's version: Revision: 1.164.2.2 (GNAT 3.15) ;; Keywords: languages ada ;; This file is part of GNU Emacs. @@ -156,8 +156,8 @@ If IS-XEMACS is non-nil, check for XEmacs instead of Emacs." ;; This call should not be made in the release that is done for the ;; official Emacs, since it does nothing useful for the latest version -(if (not (ada-check-emacs-version 21 1)) - (require 'ada-support)) +;; (if (not (ada-check-emacs-version 21 1)) +;; (require 'ada-support)) (defvar ada-mode-hook nil "*List of functions to call when Ada mode is invoked. @@ -192,6 +192,15 @@ An example is : >>>>>>>>>Value); -- from ada-broken-indent" :type 'integer :group 'ada) +(defcustom ada-continuation-indent ada-broken-indent + "*Number of columns to indent the continuation of broken lines in +parenthesis. + +An example is : + Func (Param1, + >>>>>Param2);" + :type 'integer :group 'ada) + (defcustom ada-case-attribute 'ada-capitalize-word "*Function to call to adjust the case of Ada attributes.
