ECB offers a ECB-windows for displaying a history of currently open or recently closed source-buffers, regardless of the directory the related file belongs to.
Contrary to the ECB-sources-window the ECB-History-window can be flat but
needn't. Another difference to the ECB-sources window is that the History
displays not filenames but buffer-names for buffers which are either directly
related to a file or which are indirect-buffers with a base-buffer which is
related to a file. For a description of the indirect-buffer concept see the
Emacs manual (see command
make-indirect-buffer for XEmacs).
Please note: The History of ECB is not meant to be a full replacement for the Buffers-menu of (X)Emacs! It only displays buffers which are related to a file (either directly or via indirect-buffer). All non-file-related buffers (e.g. *Help*, *grep* etc.) will never be displayed in the ECB-History-window!
IMPORTANT: If you use the POWER-click (i.e. hold down the SHIFT-key while clicking with the primary mouse button (see Using the mouse) or RETURN (see Using the keyboard)) on a node in the ECB-History-window then the related buffer will not be displayed in an edit-window but it will be scanned in the background and all its contents (e.g. methods and variables) are listed in the ECB Methods-window (see ECB Methods-window. So you can get an overlook over the buffer-contents without changing the buffer in the edit-window.
Either use one of the predefined layouts which contain the ECB-History-window
(see Changing the ECB-layout) (e.g. via C-c . l c) or create a new
ecb-layout via the command
ecb-create-new-layout and add a buffer of
type “history” into this new layout (see Creating a new ECB-layout).
You can customize if ECB should remove the related buffername-node from the
history-window after killing a buffer. This is done with the option
ecb-kill-buffer-clears-history. See the documentation of this option
for the possible choices. If you decide that ECB should not remove
the related buffername-node then this is named a “dead” buffer in the
history-window. It is displayed with a special face (see
ecb-history-dead-buffer-face), default is a kind of grey.
You can use such a dead-buffer-node in the history as all other buffername-nodes: ECB will reopen the related file in a buffer and perform the action you have choosen (see above section “Usage of the ECB-History-window”).
You can work with indirect buffers as well with direct buffers. See the
(X)Emacs manual for an introduction for indirect buffers (e.g. see the command
clone-indirect-buffer for GNU Emacs).
Indirect buffers are displayed with the face
ecb-history-indirect-buffer-face, default is an italic outline.
There is an option
which allows to customize how ECB displays indirect buffers in the
If this option is
nil then indirect-buffers are treated as
non-indirect-buffers and sorted into the history-buffer-sequence according to
the setting of
ecb-history-sort-method. Then the history contains
something like this:
<base-buffer BB> <indirect-buffer 1 of BB> <indirect-buffer 2 of BB> <indirect-buffer 3 of BB>
If not nil then indirect-buffers are always sticked to their base-buffer, ie. the base-buffer is displayed as expandable node with all its indirect-buffers as children-nodes, so the history contains something like:
[-] <base-buffer BB> | <indirect-buffer 1 of BB> | <indirect-buffer 2 of BB> `- <indirect-buffer 3 of BB>
Here the buffer with name “<base-buffer BB>” has three indirect-buffers which are display as childrens of their base-buffer.
ECB can display the history-contents “flat” or it can display buckets to
bucketize the contens according to certain criterias. This is done with the
ecb-history-make-buckets. It allows bucketizing according to the
directory, the file-extension, the major-mode or a list of regular expression
- see the documentation of this option for details.
Here is an example for a history-window bucketized according to the major-mode of the related buffers:
[-] [c++-mode] | headerfile-1.h | headerfile-2.h | codefile-1.cc `- codefile-2.cc [-] [emacs-lisp-mode] | elisp-buffer-1.el | elisp-buffer-1.el `- elisp-buffer-1.el [-] [makefile-mode] `- Makefile [-] [java-mode] | java-buffer-1.java `- java-buffer-2.java
Please note: If
ecb-history-make-buckets is nil then this is
interpreted as an empty list of regular-expressions and the history is display
with exactly one bucket. Use the value 'never if you want the? contents of the
history-window to be displayed “flat”!
You can change the bucketizing type on the fly via the popup-menu of the history-window.
See ecb-history for a list of all options currently available for customizing this ECB-windows to your needs.
