Stack overflow wrote a blog about<\/a> the reasons. You might copy & paste someone else’ insecure code into your projects and thereby introduce security vulnerabilities. That’s certainly a possibility.<\/p>\n\n\n\nBut what if you’re just copying & pasting your own code around ? Where’s the harm ?<\/p>\n\n\n\n
Suppose you have some code you really think is top notch. And you want to reuse it over & over. Suppose you want to reuse it in the event handler of numerous controls across several projects in Xojo.<\/p>\n\n\n\n
And sometime later you find there’s a bug in it.<\/p>\n\n\n\n
Now how many places do you have to fix in one project ? Or worse across many projects ?<\/p>\n\n\n\n
This is where copy paste as a code reuse technique can cause you extra work.<\/p>\n\n\n\n
You have to find & fix all that code in every project you’ve used it in.<\/p>\n\n\n\n
I’ve been using externals in SVN (yes I still use SVN)<\/p>\n\n\n\n
And in every project that uses these shared modules its a simple “update” and they have all the latest code from all the shared items.<\/p>\n\n\n\n
Git has similar capabilities.<\/p>\n\n\n\n

Code reuse is an admirable goal for any developer. Being able to re-use well written well tested code is a good thing. Especially if you can reuse it across multiple facets of one project, or across several projects. And I wouldn’t be surprised if a lot of people start out reusing code using copy paste … <\/p>\n
