Include SVN revision number in source code

Question

My requirement is simple. At the beginning of each file there should be a block comment like this:

/*
 * This file was last modified by {username} at {date} and has revision number {revisionnumber}
 */

I want to populate the {username} , {date} and {revisionnumber} with the appropriate content from SVN .

How can I achieve this with NetBeans and Subversion ? I have searched a lot but I can't find exactly what I need.

Answer 1

I looked at this question and got some useful information. It is not exactly duplicate because I am working with NetBeans but the idea is the same. This is my header:

/*
 * $LastChangedDate$
 * $LastChangedRevision$
 */

Then I go to Team > Subversion > Svn properties and add svn:keywords as property name and LastChangedDate LastChangedRevision as property value.

And when I commit from NetBeans it looks like this:

/*
 * $LastChangedDate: 2012-02-13 17:38:57 +0200 (Пн, 13 II 2012) $
 * $LastChangedRevision: 27 $
 */

Thanks all for the support! I will accept my answer because other answers do not include the NetBeans information. Nevertheless I give +1 to the other answers.

Answer 2

As this data only exists after the file was committed it should be set by SVN itself, not a client program. (And client-side processing tends to get disabled or not configured at all.) This means there is no simple template/substitute like you want, because then after the first replacement the template variables would be lost.

You can find information abut SVN's keyword substitution here . Then things like $Rev$ can be replaced by $Rev: 12 $ .

Answer 3

I followed Petar Minchev's suggestions, only I put the $LastChangedRevision$ tag not in a comment block but embedded it in a string. Now it is available to programmatically display the revision number in a Help -> About dialog.

String build = "$LastChangedRevision$";

I can later display the revision value in the about dialog using a String that has all of the fluff trimmed off.

String version = build.replace("$LastChangedRevision:", "").replace("$", "").trim();

You can do this with The SubWCRev Program .

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.

This is typically done during the build process.

If you use Linux, you can find a Linux binary here . If you wish, you could also write your own using the output of svn log .

Answer 5

I recommend a slightly different approach.

Put the following header at the top of your source files.

/*
 * This file was last modified by {username} at {date} and has revision number {revisionnumber}
 */

Then add a shell script like this

post update, checkout script

USERNAME=# // use svnversion to get username
DATE=# // use svnversion to get revisio nnumber
sed -e "s#{username}#${USERNAME}#" -e "s#{date}#${DATE}#" ${SOURCE_CONTROL_FILE} > ${SOURCE_FILE}

pre commit script

cat standard_header.txt > ${SOURCE_CONTROL_FILE}
tail --lines $((${LENGTH}-4)) ${SOURCE_FILE} >> ${SOURCE_CONTROL_FILE}
