If you write some script that run for 30 minutes or so then Crystal is a great choice. before using crystal I mostly used Ruby for scripting, but there were a lot of problems - the program often crashes after running a while due to typo/nil handling, causing a lot of time wasting - it was too slow for my case, which involving with dealing with large amount of data - doing things in parallel (fetching websites, parsing multiple files) is a lot of work, you need to use external gems for the task, and it is not always the way you want it to do there is a lot of works spent on crystal to make it enjoyable, you almost never need external libraries to do stuffs. the standard library is big and helpful.
