It is a global minor-mode which displays a couple of windows that ;; can be used to browse directories, files and file-contents like methods and ;; variables. It supports source-code parsing for semantic-supported languages ;; like Java, C, C++, Elisp and Scheme as well as for source-types supported ;; "only" by imenu or etags (e.g. perl, TeX, LaTeX etc.). ;;; Installation ;; ;; To use the Emacs code browser add the ECB files to your load path and add the ;; following line to your .emacs file: ;; ;; If you want autoloading ECB after first start: ;; ;; (require 'ecb-autoloads) ;; ;; or if you want loading the complete ECB: ;; ;; (require 'ecb) ;; ;; Optional: You can byte-compile ECB with `ecb-byte-compile' after the ;; ECB-package is loaded ;;; Requirements ;; ;; - Semantic, author-version between 1.4 and 1.4.9 ;; (http://cedet.sourceforge.net/semantic.shtml). ;; - Eieio, author-version between 0.17 and 0.17.9 ;; (http://cedet.sourceforge.net/eieio.shtml). ;; - speedbar, author version 0.14beta1 or higher ;; (http://cedet.sourceforge.net/speedbar.shtml) ;; - Optional: If Java code is edited the ECB works best when the JDEE package ;; (http://sunsite.auc.dk/jde) is installed. ;;; Activation ;; ;; ECB is either activated and started by calling ;; M-x ecb-activate ;; or ;; via the menu "Tools --> Start Code Browser (ECB)" ;; ;; ECB can also be (de)activated/toggled by M-x ecb-minor-mode. ;; ;; After activating ECB you should call `ecb-show-help' to get a detailed ;; description of what ECB offers to you and how to use ECB. ;;; Availability ;; ;; The latest version of the ECB is available at http://ecb.sourceforge.net ;;; History ;; ;; For the ChangeLog of this file see the CVS-repository.

First entry is a semantic type specifier in string-form. Current available type specifiers are for example \"class\", \"interface\", \"struct\", \"typedef\" and \"enum\". In addition to these ones there is also a special ECB type specifier \"group\" which is related to grouping tokens \(see `ecb-post-process-semantic-tokenlist' and `ecb-group-function-tokens-with-parents'). Any arbitrary specifier can be set here but if it is not \"group\" or not known by semantic it will be useless. 2. Second entry is a flag which indicates if the type-specifier string from \(1.) itself should be removed \(if there is any) from the display. 3. Third entry is the face which is used in the ECB-method window to display type-tokens with this specifier. ECB has some predefined faces for this \(`ecb-type-token-class-face', `ecb-type-token-struct-face', `ecb-type-token-typedef-face', `ecb-type-token-enum-face' and `ecb-type-token-group-face') but any arbitrary face can be set here.

Except for the words described below, the characters of each word go directly as characters of the keysequence. The whitespace that separates words is ignored. Whitespace in the macro must be written explicitly, as in \"C-c SPC\". * The special words RET, SPC, TAB, DEL, LFD, ESC, and NUL represent special control characters. The words must be written in uppercase. * A word in angle brackets, e.g., , , or , represents a function key. \(Note that in the standard configuration, the function key and the control key RET are synonymous.). You can use angle brackets on the words RET, SPC, etc., but they are not required there. * Keys can be written by their ASCII code, using a backslash followed by up to six octal digits. This is the only way to represent keys with codes above \377. * One or more prefixes M- \(meta), C- \(control), S- \(shift), A- \(alt), H- \(hyper), and s- \(super) may precede a character or key notation. For function keys, the prefixes may go inside or outside of the brackets: C- = . The prefixes may be written in any order: M-C-x = C-M-x. Prefixes are not allowed on multi-key words, e.g., C-abc, except that the Meta prefix is allowed on a sequence of digits and optional minus sign: M--123 = M-- M-1 M-2 M-3. * The `^' notation for control characters also works: ^M = C-m." :group 'ecb-general :type '(cons (choice :tag "Common prefix-key" (const :tag "No common prefix-key" :value nil) (string :tag "Prefix-key" :value "C-c ."))
