How do I manually generate text files for entire project to diff in Visual FoxPro (e.g. .sca, .vca, etc.)

The challenge is that I'm checking my FoxPro code into source control (using Mercurial, but that's not the focus of this question) and would like a quick way to get the FoxPro SCCTEXT output alongside the binary output without using the Tools > Options > Projects > Active source control provider functio开发者_运维百科nality.

For an example of the kind of output I'm looking to generate, the VFPX source contains many of these text .sca, .vca, etc. files. Is there any way to generate these files on demand?

Rather than setting a source control provider, you can hack scctext.prg (which ships with VFP) and use a project hook to generate the files - see http://paulmcnett.com/scX.php for an example implementation using Subversion.

Edit: Have you looked at the Alternate SCCText on Codeplex

Also see http://www.foxpert.com/docs/cvs.en.htm for another perspective.

Here is the code I use to genereate SCCText files for every file in my Project file. Just open your Project (to make sure it is the Active Project, then run this prg file).

(Updated 2011-06-10: Added a new feature that will only build new SCC text files if the DateTime of the original source file is newer than the existing SCC file. Essentially, this new version only generates a new SCC file if the VFP source file has been changed since the last time this was run.)

Set ClassLib to && Must clear them out, cause we're about to generate ascii files of them
