I have around 60 php files that are generated by a code generator, and after each requirement modification the files need to be changed (replace text, file rename). Can you recommend a Windows tool that can save the changes I need to make and automatically do them each time the source files are changed?
I suggest using sed.
It allows you to create change/substitution lists in a file, then run those changes against the files you are working on.
There is a small learning curve, but within 15/20 minutes you should be making progress.
