Show HN: Go 1.22 range functions with database/sql Hello HN! I published a package exploring how to use the experimental range functions coming to Go 1.22 with database/sql to stream values in and out of SQL databases. One interesting benefit of range functions I found is they enable automatic resource management (no risk of forgetting to close a sql.Rows, or missing a call to Err to check errors). The use of generics adds type safety and simplifies exchanging values between the Go application and the database. The resulting code is also quite efficient, the compiler can inline the call sites that create the range functions, which helps escape analysis and allow most values to be allocated on the stack. Let me know if you have any feedback, I hope it will be useful! https://ift.tt/SRw5voV January 17, 2024 at 12:31AM

Show HN: Interactive exercises for GNU grep, sed and awk https://ift.tt/OxeFwah

Show HN: Interactive exercises for GNU grep, sed and awk Hello! For the past few months, I've been using a Python framework called Textual to create TUI apps for interactive exercises. Released the app for GNU awk earlier today, so thought I'd create a post here. If you already know how to manage Python packages, you can use the following command to get all the three apps: pip install grepexercises sedexercises awkexercises `pipx` should also work, but I haven't tested it. The GitHub repo has the source code as well as more detailed installation instructions. You can use alternative CLI tools to solve these exercises as well. For example, Perl instead of GNU awk or ripgrep instead of GNU grep and so on. Hope you find these TUI apps useful. I'd highly appreciate your feedback. Happy learning :) https://ift.tt/Hp9kFEi August 17, 2023 at 05:13PM
