Sed script to trim C/C++ commentshttps://bash.cyberciti.biz/academic/sed-remove-c-cpp-comments/ |
|
I like coding for ansi C. As the lowest-common-denominator, it's portable. And really the later extensions to C don't add anything that I've found important. But sometimes, you need to use somebody else's code for something, e.g. loading images, and they've used // C++ style comments. Which breaks your lovely ansi compile. You'd be mad to remove the comments by hand (especially if the author releases new versions with bug fixes), so this script can be used to strip the comments completely and put the result in another file. You could run the script automatically as part of your build process, or only run it when the file in question changes. |

Good, but it would be more useful to change the comments from '//' to '/* */'. That way you don't lose the comments.

Indeed, but did you see the sed script? I have no idea how that works! I'm not losing the comments though; I'm just outputting a copy, e.g. stb_image.h becomes stb_image_ansi.h, then I include that instead. But I agree; ideally it would just convert the comments. I just didn't fancy writing it myself! |

If you have Ruby installed you can do ... ... although it only works on one file at time. Usage: |
