I'm using PN with Tortoise SVN for a C language project. I'd like to somehow embed the revision tag from subversion into a datacode in my source so the program outputs the revision number of the subversion version used.
Any tips or references I could use to figure out how to do that? Maybe a snippet of code to embed in the Makefile?
Or perhaps something else?
THanks

Good idea, but trickier than you might think. Use the 'subwcrev' command:
http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-subwcrev.html
I create a file "version-template.txt" in my project. Then I add a batch file (you could add in your makefile) to run:
subwcrev version-template.txt version.txt
Now you have version.txt with the program's revision, which you can load when you want to output the revision in your program. I also svn:ignore version.txt, so it doesn't get committed to SVN.
There's also a built-in SVN command that handles property replacement, like $REV$, but that only handles per-file revisions so wont work for this purpose. Too bad, since it's seamless (happens after checkout).
