SubWCRev is Windows console program which can be used to read the status of a Subversion working copy and optionally perform keyword substitution in a template file. This is often used as part of the build process as a means of incorporating working copy information into the object you are building. Typically it might be used to include the revision number in an “About” box.
SubWCRev reads the Subversion status of all files in a working copy, excluding externals by default. It records the highest commit revision number found, and the commit timestamp of that revision, it also records whether there are local modifications in the working copy, or mixed update revisions. The revision number, update revision range and modification status are displayed on stdout.
SubWCRev.exe is called from the command line or a script, and is controlled using the command line parameters.
SubWCRev WorkingCopyPath [SrcVersionFile DstVersionFile] [-nmdfe]
WorkingCopyPath is the path to the working
copy being checked. You can only use SubWCRev on working copies,
not directly on the repository. The path may be absolute or
relative to the current working directory.
If you want SubWCRev to perform keyword substitution, so that
fields like repository revision and URL are saved to a text
file, you need to supply a template file
SrcVersionFile
and an output file
DstVersionFile
which contains the substituted version of the template.
There are a number of optional switches which affect the way
SubWCRev works. If you use more than one, they must be specified
as a single group, e.g.
-nm, not
-n -m.
Table 5.1. List of available command line switches
| Switch | Description |
|---|---|
| -n |
If this switch is given, SubWCRev will exit with
ERRORLEVEL 7 if the working copy
contains local modifications. This may be used to
prevent building with uncommitted changes present.
|
| -N |
If this switch is given, SubWCRev will exit with
ERRORLEVEL 11 if the working copy
contains unversioned items that are not ignored.
|
| -m |
If this switch is given, SubWCRev will exit with
ERRORLEVEL 8 if the working copy
contains mixed revisions. This may be used to prevent
building with a partially updated working copy.
|
| -d |
If this switch is given, SubWCRev will exit with
ERRORLEVEL 9 if the destination file
already exists.
|
| -f | If this switch is given, SubWCRev will include the last-changed revision of folders. The default behaviour is to use only files when getting the revision numbers. |
| -e |
If this switch is given, SubWCRev will examine
directories which are included with
svn:externals,
but only if they are from the same repository.
The default behaviour is to ignore externals.
|
| -E |
If this switch is given, same as -e,
but it ignores the externals with explicit revisions,
when the revision range inside of them is only
the given explicit revision in the properties.
So it doesn't lead to mixed revisions.
|
| -x | If this switch is given, SubWCRev will output the revision numbers in HEX. |
| -X | If this switch is given, SubWCRev will output the revision numbers in HEX, with '0X' prepended. |
| -q | If this switch is given, SubWCRev will perform the keyword substitution without showing working copy status on stdout. |
If there is no error, SubWCRev returns zero. But in case an error occurs, the error message is written to stderr and shown in the console. And the returned error codes are:
Table 5.2. List of SubWCRev error codes
| Error Code | Description |
|---|---|
| 1 | Syntax error. One or more command line parameters are invalid. |
| 2 | The file or folder specified on the command line was not found. |
| 3 | The input file could not be opened, or the target file could not be created. |
| 4 | Could not allocate memory. This could happen if e.g. the source file is too big. |
| 5 | The source file can not be scanned properly. |
| 6 | SVN error: Subversion returned with an error when SubWCRev tried to find the information from the working copy. |
| 7 |
The working copy has local modifications.
This requires the -n switch.
|
| 8 |
The working copy has mixed revisions.
This requires the -m switch.
|
| 9 |
The output file already exists.
This requires the -d switch.
|
| 10 | The specified path is not a working copy or part or one. |
| 11 |
The working copy has unversioned files or folders in it.
This requires the -N switch.
