This group contains settings for the version-control-support of ECB:
Which directories should be excluded from VC-state-check. If a
directory matches any of the regexps of this option the VC-state of
its sources will not be checked - This option takes only effect if
ecb-vc-enable-support
is not nil.
Enable support for version-control (VC) systems. If on then in the
directories-buffer (if the value of the option
ecb-show-sources-in-directories-buffer
is on for current
layout), the sources-buffer and the history-buffer all file-items are
displayed with an appropriate icon in front of the item-name to
indicate the VC-state of this item. If off then no
version-control-state checking is done.
Because this check can be take some time if files are managed by a not
local Version-control-server ECB performs this check stealthy (see
ecb-stealthy-tasks-delay
) so normally there should no
performance-decrease or additional waiting-time for the user. But to
get sure this option offers three choices: t
,
unless-remote
and nil
. See the option
ecb-prescan-directories-for-emptyness
for an explanation for
these three choices.
The option ecb-vc-directory-exclude-regexps
offers are more
fine granularity to exclude the sources of certain directories from
the VC-state-check.
See ecb-vc-supported-backends
and ecb-vc-state-mapping
how to customize the VC-support itself.
Mapping between VC-states from the backends and ECB-known VC-states. ECB understands the following state-values:
up-to-date
The working file is unmodified with respect to the latest version on the current branch, and not locked.
edited
The working file has been edited by the user. If locking is used for the file, this state means that the current version is locked by the calling user.
needs-patch
The file has not been edited by the user, but there is a more recent version on the current branch stored in the master file.
needs-merge
The file has been edited by the user, and there is also a more recent version on the current branch stored in the master file. This state can only occur if locking is not used for the file.
added
The working file has already been added/registered to the VC-system but not yet commited.
unlocked-changes
The current version of the working file is not locked, but the working file has been changed with respect to that version. This state can only occur for files with locking; it represents an erroneous condition that should be resolved by the user.
ignored
The version-control-system ignores this file (e.g. because included in a .cvsignore-file in case of CVS).
unknown
The state of the file can not be retrieved; probably the file is not under a version-control-system.
All state-values a check-vc-state-function of
ecb-vc-supported-backends
can return must have a mapping to one
of the ECB-state-values listed above. If for a certain
backend-VC-state no mapping can be found then per default ’edited is
assumed!
The default value of this option maps already the possible returned
state-values of vc-state
and vc-recompute-state
(both
GNU Emacs) and vc-cvs-status
(Xemacs) to the
ECB-VC-state-values.
Define how to to identify the VC-backend and how to check the state. The value of this option is a list containing cons-cells where the car is a function which is called to identify the VC-backend for a DIRECTORY and the cdr is a function which is called to check the VC-state of the FILEs contained in DIRECTORY.
Identify-backend-function: It gets a full directory-name as argument - always without ending slash (rsp. backslash for native Windows-XEmacs) - and has to return a unique symbol for the VC-backend which manages that directory (e.g. ’CVS for the CVS-system or ’RCS for the RCS-system) or nil if the file is not managed by a version-control-system.
Check-vc-state-function: It gets a full filename (ie. incl. the complete
directory-part) and has to return a symbol which indicates the VC-state of
that file. The possible returned values of such a check-vc-state-function have
to be mapped with ecb-vc-state-mapping
to the allowed ECB-VC-state values.
ECB runs for a certain DIRECTORY all identify-backend-functions in that order they are listed in this option. For the first which returns a value unequal nil the associated check-state-function is used to retrieve the VC-state of all sourcefiles in that DIRECTORY.
There is no need for the identify-backend-function or the check-vc-state-function to cache any state because ECB automatically caches internally all necessary informations for directories and files for best possible performance.
To prepend ECB from checking the VC-state for any file set
ecb-vc-enable-support
to nil.
Default value: Support for CVS, RCS, SCCS, Subversion, Git, Bazaar, Monotone
and Mercurial. To identify the VC-backend the functions
ecb-vc-dir-managed-by-CVS
, ecb-vc-dir-managed-by-RCS
rsp.
ecb-vc-dir-managed-by-SCCS
rsp. ecb-vc-dir-managed-by-SVN
rsp.
ecb-vc--dir-managed-by-GIT
rsp. ecb-vc-dir-managed-by-BZR
rsp.
ecb-vc-dir-managed-by-MTN
rsp. ecb-vc-dir-managed-by-HG
are used.
For all eight backends the function ecb-vc-state
of the
VC-package is used by default (which uses a heuristic and
therefore faster but less accurate approach), but there is also
ecb-vc-recompute-state
available which is an alias for
vc-recompute-state
(which returns accurate state-values by calling the
backend which can be slow especialy for remote root-repositories!)
Example: If ecb-vc-recompute-state
(to get real state-values not
only heuristic ones) should be used to check the state for CVS-managed files
and ecb-vc-state
for all other backends then an element
(ecb-vc-dir-managed-by-CVS . ecb-vc-recompute-state) should be added at the
beginning of this option.
