如果提供了源文件和目的文件，SubWCRev 会复制源文件到目标文件，执行如下所属的关键字替换:
表 6.3. 可用关键字列表
| 关键字 | 描述 |
|---|---|
| $WCREV$ | 用工作副本中最高的提交版本来替换 |
| $WCREV&$ | 用工作副本中的最高提交修订版本号替换，ANDed with the value after the & char. 例如：$WCREV&0xFFFF$ |
| $WCREV-$, $WCREV+$ | Replaced with the highest commit revision in the working copy, with the value after the + or - char added or subtracted. For example: $WCREV-1000$ |
| $WCDATE$, $WCDATEUTC$ | Replaced with the commit date/time of the highest commit revision. By default, international format is used: yyyy-mm-dd hh:mm:ss. Alternatively, you can specify a custom format which will be used with strftime(), for example: $WCDATE=%a %b %d %I:%M:%S %p$. For a list of available formatting characters, look at the 在线引用. |
| $WCNOW$, $WCNOWUTC$ | Replaced with the current system date/time. This can be used to indicate the build time. Time formatting can be used as described for $WCDATE$. |
| $WCRANGE$ | Replaced with the update revision range in the working copy. If the working copy is in a consistent state, this will be a single revision. If the working copy contains mixed revisions, either due to being out of date, or due to a deliberate update-to-revision, then the range will be shown in the form 100:200. |
| $WCMIXED$ | 当有混合版本时用 TText 替换 $WCMIXED?TText:FText$，否则用 FText 替换。 |
| $WCMODS$ | 若本地存在修改，就用 TText 替换 $WCMODS?TText:FText$，否则用 FText 替换。 |
| $WCUNVER$ | $WCUNVER?TText:FText$ is replaced with TText if there are unversioned items in the working copy, or FText if not. |
| $WCEXTALLFIXED$ | $WCEXTALLFIXED?TText:FText$ is replaced with TText if all externals are fixed to an explicit revision, or FText if not. |
| $WCISTAGGED$ | $WCISTAGGED?TText:FText$ is replaced with TText if the repository URL contains the tags classification pattern, or FText if not. |
| $WCURL$ | 用传递给SubWCRev的工作目录的版本库地址替换。 |
| $WCINSVN$ | $WCINSVN?TText:FText$ is replaced with TText if the entry is versioned, or FText if not. |
| $WCNEEDSLOCK$ | 若入口有svn:needs-lock属性设定，就用 TText 替换 $WCNEEDSLOCK?TText:FText$，否则用FText 替换。 |
| $WCISLOCKED$ | 若入口被锁定，就用 TText 替换 $WCISLOCKED?TText:FText$，否则用 FText 替换。 |
| $WCLOCKDATE$, $WCLOCKDATEUTC$ | Replaced with the lock date. Time formatting can be used as described for $WCDATE$. |
| $WCLOCKOWNER$ | 用锁定所有者的名字来替换 |
| $WCLOCKCOMMENT$ | 用锁定的备注来替换 |
| $WCUNVER$ | $WCUNVER?TText:FText$ is replaced with TText if there are unversioned files or folders in the working copy, or FText if not. |
SubWCRev does not directly support nesting of expressions, so for example you cannot use an expression like:
#define SVN_REVISION "$WCMIXED?$WCRANGE$:$WCREV$$"
But you can usually work around it by other means, for example:
#define SVN_RANGE $WCRANGE$
#define SVN_REV $WCREV$
#define SVN_REVISION "$WCMIXED?SVN_RANGE:SVN_REV$"
Some of these keywords apply to single files rather than to an entire working copy, so it only makes sense to use these when SubWCRev is called to scan a single file. This applies to $WCINSVN$, $WCNEEDSLOCK$, $WCISLOCKED$, $WCLOCKDATE$, $WCLOCKOWNER$ and $WCLOCKCOMMENT$.
