If you need to access Subversion revision information from other
programs, you can use the COM interface of SubWCRev. The object to
create is SubWCRev.object, and the following
methods are supported:
Table 5.3. COM/automation methods supported
| Method | Description |
|---|
| .GetWCInfo |
This method traverses the working copy gathering the
revision information. Naturally you must call this before
you can access the information using the remaining methods.
The first parameter is the path.
The second parameter should be true if you want to include
folder revisions. Equivalent to the -f
command line switch.
The third parameter should be true if you want to include
svn:externals. Equivalent to the -e
command line switch.
|
| .Revision |
The highest commit revision in the working copy.
Equivalent to $WCREV$.
|
| .Date |
The commit date/time of the highest commit revision.
Equivalent to $WCDATE$.
|
| .Author |
The author of the highest commit revision, that is, the
last person to commit changes to the working copy.
|
| .MinRev | The minimum update revision, as shown in $WCRANGE$ |
| .MaxRev | The maximum update revision, as shown in $WCRANGE$ |
| .HasModifications | True if there are local modifications |
| .Url |
Replaced with the repository URL of the working
copy path used in GetWCInfo.
Equivalent to $WCURL$.
|
| .IsSvnItem |
True if the item is versioned.
|
| .NeedsLocking |
True if the item has the svn:needs-lock
property set.
|
| .IsLocked |
True if the item is locked.
|
| .LockCreationDate |
String representing the date when the lock was
created, or an empty string if the item is not locked.
|
| .LockOwner |
String representing the lock owner, or an empty
string if the item is not locked.
|
| .LockComment |
The message entered when the lock was created.

The following example shows how the interface might be used.

The following listing is an example on how to use the SubWCRev COM
object from C#:
using LibSubWCRev;
SubWCRev sub = new SubWCRev();
sub.GetWCInfo("C:\\PathToMyFile\\MyFile.cc", true, true);
if (sub.IsSvnItem == true)
{
MessageBox.Show("versioned");
}
else
{
MessageBox.Show("not versioned");
}
