Previous: Stealthy background tasks, Up: Usage of ECB
ECB offers a lot of interactive commands. Some of these commands prompt the user in the minibuffer if called with a prefix argument.
Example: If ecb-clear-history
is called with a prefix argument
then you will be prompted in the minibuffer with:
Clear from history: [all, not-existing-buffers, existing-buffers]
You can choose one of the options enclosed in brackets with TAB-completion; hitting RET direct after the prompt chooses auto. the first offered option (in the example above “all”).
Please note: The following interactive commands of ECB are
listed without the prefix “ecb-” (e.g. the command
ecb-activate
is listed with name “activate”). This has been
done for a better readable command index. See Command Index.
Activates ECB and creates the special buffers for the choosen layout. For the layout see
ecb-layout-name
. This function always raises the ECB-frame if called from another frame. This is the same as callingecb-minor-mode
with a positive argument.
Add all current file-buffers to the history-buffer of ECB. Dependend on the value of
ecb-history-sort-method
afterwards the history is sorted either by name or by extension. Ifecb-history-sort-method
is nil the most recently used buffers are on the top of the history and the seldom used buffers at the bottom.
Synchronize the analyse buffer with the current buffer and point. This means in fact display the current analysis for current point.
Select a layout-name from all current available layouts (TAB-completion is offered) and change the layout to the selected layout-name. If optional argument PRESELECT-TYPE is not nil then you can preselect a layout-type \(TAB-completion is offered too) and then you will be asked only for layouts of that preselected type. Note: This function works by changing the option
ecb-layout-name
but only for current Emacs-session.
Start process for interactively creating a new ECB-layout (see Creating a new ECB-layout).
Cycles through all ecb-buffers of current layout by maximizing exactly one of the ecb-windows after every cycle-step.
Cycle through all compilation buffers currently open and display them within the compilation window
ecb-compile-window
. If the currently opened buffer within the compilation window is not a compilation buffer, we jump to the first compilation buffer. If not we try to loop through all compilation buffers. If we hit the end we go back to the beginning.If CHOOSE-BUFFER is not
nil
then the user will be prompted for the compilation-buffer to switch to.
Select a layout-name for a layout created by
ecb-create-new-layout
and delete this layout. This means the layout-definition is removed from the fileecb-create-layout-file
and the layout-function and associated aliases are unbound.
Display the most important NEWS after an ECB-upgrade. If you call this function but no ECB-upgrade has been performed before starting ECB then nothing is display unless FULL-NEWS is not nil.
If FULL-NEWS is not nil then the NEWS-file is displayed in another window.
Display a information-buffer which options have been upgraded or reset. Offers two buttons where the user can decide if the upgraded options should also being saved by ECB for future settings or if the buffer should be killed.
If saving is possible this command display where the options would be saved. It is that file Emacs uses to save customize-settings. This file is “computed” from the settings in
custom-file
anduser-init-file
(see the documentation of these variables).ECB automatically makes a backup-file of that file which will be modified by storing the upgraded rsp. renamed ECB-options. This backup file gets a unique name by adding a suffix “.before_ecb_<version>” to the name of the modified file. If such a file already exists ECB adds a unique number to the end of the filename to make the filename unique. This is a safety mechanism if something fails during storing the upgraded options, so you never lose the contents of your customization-file!
Download ECB from the ECB-website and install it. For this the option
ecb-download-url
must be set correct, whereas the default value of this option should always be correct.If
ecb-download-package-version-type
is set to -1 (means asking for a version) then you will be ask in the minibuffer for the version to download. Otherwise ECB downloads autom. the latest version available for the type specified inecb-download-package-version-type
. If no newer version than the current one is available no download will be done.For details about downloading and what requirements must be satisfied see function
ecb-package-download
and optionecb-download-package-version-type
!After successful downloading the new ECB will be installed in a subdirectory of
ecb-download-install-parent-dir
. After adding this subdirectory toload-path
and restarting Emacs the new ECB version can be activated byecb-activate
.If current running ECB is installed as regular XEmacs-package and not with the archive available at the ECB website then this function asks for proceeding!
Download semantic from the semantic-website and install it. For this the variable
ecb-cedet-url
must be set correct, whereas the default value of this variable should always be correct.If
ecb-download-package-version-type
is set to -1 (means asking for a version) then you will be ask in the minibuffer for the version to download. Otherwise ECB downloads autom. the latest version available for the type specified inecb-download-package-version-type
. If no newer version than the current one is available no download will be done.For details about downloading and what requirements must be satisfied see function
ecb-package-download
and optionecb-download-package-version-type
!After successful downloading the new semantic will be installed in a subdirectory of
ecb-download-install-parent-dir
. After adding this new subdirectory toload-path
and restarting Emacs the new semantic version is loaded and is used after next start of ECB.If current running semantic is installed as regular XEmacs-package and not with the archive available at the semantic website then this function asks for proceeding!
Set the expand level of the nodes in the ECB-methods-buffer.
This command asks in the minibuffer for an indentation level LEVEL. With this LEVEL you can precisely specify which level of nodes should be expanded. LEVEL means the indentation-level of the nodes.
A LEVEL value X means that all nodes with an indentation-level <= X are expanded and all other are collapsed. A negative LEVEL value means all visible nodes are collapsed.
Nodes which are not indented have indentation-level 0!
Which node-types are expanded (rsp. collapsed) by this command depends on the options
ecb-methods-nodes-expand-spec
andecb-methods-nodes-collapse-spec
! With optional argument FORCE-ALL all tags will be expanded/collapsed regardless of the values of these options.Examples:
- LEVEL = 0 expands only nodes which have no indentation itself.
- LEVEL = 2 expands nodes which are either not indented or indented indented once or twice
- LEVEL ~ 10 should normally expand all nodes expect there are nodes which are indented deeper than 10.
Note 1: This command switches off auto. expanding of the method-buffer if
ecb-expand-methods-switch-off-auto-expand
is not nil. But it can be switched on again quickly withecb-toggle-auto-expand-tag-tree
or [C-c . a].Note 2: All this is only valid for file-types parsed by semantic. For other file types which are parsed by imenu or etags (see
ecb-process-non-semantic-files
) FORCE-ALL is always true!
Dump the current semantic-tags in special buffer and display them.
Synchronize the eshell with the directory of current source-buffer. This is only done if the eshell is currently visible in the compile-window of ECB and if either this function is called interactively or
ecb-eshell-synchronize
is not nil.
Set the expand level of the nodes in the ECB-directories-buffer. For argument LEVEL see
ecb-expand-methods-nodes
.Be aware that for deep structured paths and a lot of source-paths this command can last a long time - depending on machine- and disk-performance.
Make the ECB-directories window the current window. If
ecb-use-speedbar-instead-native-tree-buffer
isdir
then goto to the speedbar-window.
Make the last selected edit-window window the current window. This is the same as if
ecb-mouse-click-destination
is set tolast-point
.
Make the ECB-methods window the current window. If
ecb-use-speedbar-instead-native-tree-buffer
ismethod
then goto to the speedbar-window.
Make the ECB-sources window the current window. If
ecb-use-speedbar-instead-native-tree-buffer
issource
then goto to the speedbar-window.
Apply a filter to the history-buffer to reduce the number of entries. So you get a better overlooking. There are three choices:
- Filter by extension: Just insert the extension you want the History-buffer being filtered. Insert the extension without leading dot!
- Filter by regexp: Insert the filter as regular expression.
- No filter: This means to display an entry for all currently living file-buffers.
Display in the ECB-methods-buffer the contents (methods, attributes etc...) of the class which contains the definition of the “thing” under point (this can be a variable-name, class-name, method-name, attribute-name). This function needs the same requirements to work as the method-completion feature of JDEE (see
jde-complete
)!. The source-file is searched first injde-sourcepath
, then injde-global-classpath
, then in $CLASSPATH, then in current-directory.Works only for classes where the source-code (i.e. the *.java-file) is available.
Maximize the ECB-analyse-window. I.e. delete all other ECB-windows, so only one ECB-window and the edit-window(s) are visible (and maybe a compile-window). Works also if the ECB-analyse-window is not visible in current layout.
Maximize the ECB-directories-window, i.e. delete all other ECB-windows, so only one ECB-window and the edit-window(s) are visible (and maybe a compile-window). Works also if the ECB-directories-window is not visible in current layout.
Maximize the ECB-sources-window, i.e. delete all other ECB-windows, so only one ECB-window and the edit-window(s) are visible (and maybe a compile-window). Works also if the ECB-sources-window is not visible in current layout.
Maximize the ECB-methods-window, i.e. delete all other ECB-windows, so only one ECB-window and the edit-window(s) are visible (and maybe a compile-window). Works also if the ECB-methods-window is not visible in current layout.
Maximize the ECB-history-window, i.e. delete all other ECB-windows, so only one ECB-window and the edit-window(s) are visible (and maybe a compile-window). Works also if the ECB-history-window is not visible in current layout.
Maximize the ECB-speedbar-window, i.e. delete all other ECB-windows, so only one ECB-window and the edit-window(s) are visible (and maybe a compile-window). Does nothing if the speedbar-window is not visible within the ECB-frame.
Apply a filter to the Methods-buffer to reduce the number of entries. So you get a better overlooking. There are six choices:
- Filter by protection: Just insert the protection you want the Methods-buffer being filtered: private, protected or public!
- Filter by regexp: Insert the filter as regular expression.
- Filter by tag-class: You can filter by the tag-classes of current major-mode. The available tag-classes come from the variable
semantic--symbol->name-assoc-list
. The are normally methods, variables etc.- Filter by current type: In languages which have types like Java or C++ this filter displays only the current type and all its members (e.g. attributes and methods). If ECB can not identify the current type in the source-buffer or in the methods-window then nothing will be done.
- Filter by a filter-function: Such a function gets two arguments: a tag and the source-buffer of this tag. If the tag should be displayed (i.e. not being filtered out) then the function has to return not nil otherwise nil.
- No special filter: This means to display all tags specified with the option
ecb-show-tokens
. If currently some of the above filters are applied they will be all removed.- Delete the last added: This removes only the topmost filter-layer, means that filter added last.
The protection-, current-type- and the tag-class-filter are only available for semantic-supported sources.
Be aware that the tag-list specified by the option
ecb-show-tags
is the basis of all filters, i.e. tags which are excluded by that option will never be shown regardless of the filter type here!All tags which match the applied filter(s) will be displayed in the Methods-buffer.
If called with a prefix-argument or when optional arg INVERSE is not nil then an inverse filter is applied to the Methods-buffer, i.e. all tags which do NOT match the choosen filter will be displayed in the Methods-buffer!
Per default the choosen filter will be applied on top of already existing filters. This means that filters applied before are combined with the new filter. This behavior can changed via the option
ecb-methods-filter-replace-existing
. But regardless of the setting inecb-methods-filter-replace-existing
applying one of the not-inverse filters protection, tag-class or current-type always replaces exactly already existing filters of that type. On the other hand applying more than one inverse tag-class- or protection-filter can make sense.Such a filter is only applied to the current source-buffer, i.e. each source-buffer can have its own tag-filters.
The current active filter will be displayed in the modeline of the Methods-buffer [regexp, prot (= protection), tag-class, function (= filter-function)]. If an inverse filter has been applied then this is signalized by a preceding caret ^. If currently more than 1 filter is applied then always the top-most filter is displayed in the modeline but the fact of more than 1 filter is visualized by the number of the filters - included in parens. You can see all currently applied filters by moving the mouse over the filter-string in modeline of the Methods-buffer: They will displayed as help-echo.
See the option
ecb-default-tag-filter
if you search for automatically applied default-tag-filters.
Display in the Methods-buffer only the current type and its members. For further details see
ecb-methods-filter
.
Remove the most recent filter from the Methods-buffer. For further details see
ecb-methods-filter
.
Filter the methods-buffer by a function. If INVERSE is not nil (called with a prefix arg) then an inverse filter is applied. For further details see
ecb-methods-filter
.
Remove any filter from the Methods-buffer. For further details see
ecb-methods-filter
.
Filter the methods-buffer by protection. If INVERSE is not nil (called with a prefix arg) then an inverse filter is applied. For further details see
ecb-methods-filter
.
Filter the methods-buffer by a regexp. If INVERSE is not nil (called with a prefix arg) then an inverse filter is applied. For further details see
ecb-methods-filter
.
Filter the methods-buffer by tag-class. If INVERSE is not nil (called with a prefix arg) then an inverse filter is applied. For further details see
ecb-methods-filter
.
Toggle ECB minor mode. With prefix argument ARG, turn on if positive, otherwise off. Return non-
nil
if the minor mode is enabled.
Go backward in the navigation history-list, see Back/forward navigation.
Updates the methods buffer with the current buffer after deleting the complete previous parser-information, means no semantic-cache is used! Point must stay in an edit-window otherwise nothing is done. This method is merely needed for semantic parsed buffers if semantic parses not the whole buffer because it reaches a not parse-able code or for buffers not supported by semantic but by imenu or etags.
Examples when a call to this function can be necessary:
- If an Elisp-file is parsed which contains in the middle a defun X where the closing ) is missing then semantic parses only until this defun X is reached and you will get an incomplete ECB-method buffer. In such a case you must complete the defun X and then call this function to completely reparse the Elisp-file and rebuild the ECB method buffer!
- For not semantic supported buffers which can be parsed by imenu or etags (see
ecb-process-non-semantic-files
) because for these buffers there is no built-in auto-rebuild mechanism. For these buffers this command callsecb-rebuild-methods-buffer-for-non-semantic
.For non-semantic-sources supported by etags the option
ecb-auto-save-before-etags-methods-rebuild
is checked before rescanning the source-buffer and rebuilding the methods-buffer.If point is in one of the ecb-windows or in the compile-window then this command rebuids the methods-buffer with the contents of the source-buffer the last selected edit-window.
Redraw the ECB screen.
Do not call this command from elisp-program but only interactively!
Called without a prefix-argument the state of the ECB-frame-layout will preserved. This means:
- The state of compile-window (hidden or visible) will be preserved but if visible then the height will be as specified in
ecb-compile-window-height
.- The state of the ECB-windows will be preserved (hidden or visible) but if visible then the sizes will be as specified in the layout (and with the options
ecb-windows-width
andecb-windows-height
) or as stored withecb-store-window-sizes
.If called with ONE prefix-argument ([C-u]) then the layout will be drawn with all ECB-windows and also with a visible compile-window (when
ecb-compile-window-height
is not nil). The splitting-state of the edit-area will be preserved.If called with TWO prefix-arguments (i.e. hitting [C-u] twice: ([C-u] [C-u]) then an emergency-redraw will be performed. This means the same as if called with one prefix-argument (s.a.) but the splitting-state of the edit-area will NOT be preserved but all edit-windows besides the current one will be deleted. Use this only if there are some anomalies after standard redraws!
If the variable
ecb-redraw-layout-quickly
is not nil then the redraw is done by theecb-redraw-layout-quickly
function, otherwise byecb-redraw-layout-full
.Please not: It's strongly recommended to use the quick redraw only if you have really slow machines where a full redraw takes several seconds because the quick redraw is not really safe and has some annoying drawbacks! On normal machines the full redraw should be done in << 1s so there should be no need for the quick version!
Resets the sizes of the ECB windows to their default values.
Sets the sizes of the ECB windows to their stored values. See option
ecb-layout-window-sizes
and commandecb-store-window-sizes
.
Shows the online help of ECB either in Info or in HTML format depending on the value of
ecb-show-help-format
. If called with prefix argument, i.e. if FORMAT is not nil then the user is prompted to choose the format of the help (Info or HTML). If an error about not finding the needed help-file occurs please take a look at the optionsecb-help-info-start-file
andecb-help-html-start-file
!Note: If you got ECB as a standard XEmacs-package maybe the HTML-online-documentation is not included.
Select a name of a layout and shows the documentation of the associated layout-function. At least for the built-in layouts the documentation contains a picture of the outline of the chosen layout.
Show tip of the day if
ecb-tip-of-the-day
is not nil or if called interactively.
Apply a filter to the sources-buffer to reduce the number of entries. So you get a better overlooking. There are three choices:
- Filter by extension: Just insert the extension you want the Sources-buffer being filtered. Insert the extension without leading dot!
- Filter by regexp: Insert the filter as regular expression.
- No filter: This means to display an entry for every file in the current selected directory (all except these filter already filtered out by
ecb-source-file-regexps
andecb-sources-exclude-cvsignore
).Such a filter is only applied to the current selected directory, i.e. each directory has its own filtered sources-buffer.
Stores the sizes of the ECB windows for the current layout. The size of the ECB windows will be set to their stored values when
ecb-redraw-layout
orecb-restore-window-sizes
is called. To reset the window sizes to their default values callecb-restore-default-window-sizes
. Please read also the documentation ofecb-layout-window-sizes
!The windows sizes are stored per default as fractions of current frame-width and -height of the ecb-frame, so the stored values will “work” for other frame sizes too. If a permanent compile-window is visible then ECB will tell you that window-sizes should be stored with hidden compile-window and ask you if you want proceed; if you proceed then the window-heights will be stored as fractions of current (frame-height minus current visible compile-window-height) so you should ensure that the current compile-window has its standard-height as specified in
ecb-compile-window-height
!. If FIX is not nil (means called with a prefix argument) then always the fixed values of current width and height are stored!
Submit a problem report for the ECB to the ECB mailing-list. This command generates in the edit-window a problem-report which contains already the current values of all ECB options, the current backtrace-buffer if there is any and the current message-buffer. You will be asked for a problem-report subject and then you must insert a description of the problem. Please describe the problem as detailed as possible!
Toggle auto expanding of the ECB-methods-buffer. With prefix argument ARG, make switch on if positive, otherwise switch off. If the effect is that auto-expanding is switched off then the current value of
ecb-auto-expand-tag-tree
is saved so it can be used for the next switch on by this command.
Toggle the visibility of the compile-window of ECB. With prefix argument ARG, make visible if positive, otherwise invisible. The height of the compile-window is always the current value of
ecb-compile-window-height
! If called andecb-compile-window-height
is nil then ECB asks for the height of the compile-window, sets this height as new value ofecb-compile-window-height
and displays the compile-window (so if you have called this command by mistake and you do not want a compile-window you have to quit with <C-g>).
Toggle whether the
ecb-compile-window
is enlarged or not. If ARG > 0 then shrink or enlarge the the compile-window according to the value ofecb-enlarged-compilation-window-max-height
. But never shrink below the value ofecb-compile-window-height
. If ARG <= 0 then shrinkecb-compile-window
toecb-compile-window-height
and if ARG is nil then toggle the enlarge-state.
Toggle visibility of the ECB-windows. With prefix argument ARG, make visible if positive, otherwise invisible. This has nothing to do with (de)activating ECB but only affects the visibility of the ECB windows. ECB minor mode remains active!
Toggles between the layouts defined in
ecb-toggle-layout-sequence
(See also optionecb-show-sources-in-directories-buffer
). Note: This function works by changing the optionsecb-layout-name
but only for current Emacs-session.If optional argument LAST-ONE is not nil (e.g. called with a prefix-arg) then always the last selected layout was choosen regardless of the setting in
ecb-toggle-layout-sequence
. The last selected layout is always that layout which was current direct before the most recent layout-switch. So now a user can switch to another layout via `ecb-change-layout' and always come back to his previous layout via [C-u]ecb-toggle-layout
.
Toggle the state of
ecb-scroll-other-window-scrolls-compile-window
. With prefix argument ARG, set it tot
, otherwise tonil
. For all details about the scroll-behavior ofscroll-other-window
see the advice documentation ofother-window-for-scrolling
.
Toggle auto synchronizing of the ECB-windows. With prefix argument ARG, switch on if positive, otherwise switch off. If the effect is that auto-synchronizing is switched off then the current value of the option
ecb-window-sync
is saved so it can be used for the next switch on by this command. See also the optionecb-window-sync
.
Check for all ECB-options if their current value is compatible to the defined type. If not upgrade it to the new type or reset it to the default-value of current ECB. Try also to upgrade renamed options. Displays all upgraded or reset options with their old (before the upgrade/reset) and new values.
Synchronizes all special ECB-buffers with current buffer.
Depending on the contents of current buffer this command performs different synchronizing tasks but only if ECB is active and point stays in an edit-window.
- If current buffer is a file-buffer then all special ECB-tree-buffers are synchronized with current buffer.
- If current buffer is a dired-buffer then the directory- and the sources-tree-buffer are synchronized if visible
In addition to this the hooks in
ecb-current-buffer-sync-hook
run.
Most of these functions are also available via the menu “ECB” and
also via the ECB key-map with prefix C-c . (see
ecb-minor-mode
for a complete list of the keybindings).
