https://bugzilla.redhat.com/show_bug.cgi?id=2166239 Bug ID: 2166239 Summary: Review Request: ghc-fmt - A new formatting library Product: Fedora Version: rawhide Status: NEW Component: Package Review Assignee: nobody@xxxxxxxxxxxxxxxxx Reporter: petersen@xxxxxxxxxx QA Contact: extras-qa@xxxxxxxxxxxxxxxxx CC: package-review@xxxxxxxxxxxxxxxxxxxxxxx Target Milestone: --- Classification: Fedora Spec URL: https://petersen.fedorapeople.org/reviews/ghc-fmt/ghc-fmt.spec SRPM URL: https://petersen.fedorapeople.org/reviews/ghc-fmt/ghc-fmt-0.6.3.0-1.fc38.src.rpm Description: A new formatting library that tries to be simple to understand while still being powerful and providing more convenience features than other libraries (like functions for pretty-printing maps and lists, or a function for printing arbitrary datatypes using generics). A comparison with other libraries: * 'printf' (from 'Text.Printf') takes a formatting string and uses some type tricks to accept the rest of the arguments polyvariadically. It's very concise, but there are some drawbacks – it can't produce 'Text' (you'd have to 'T.pack' it every time) and it doesn't warn you at compile-time if you pass wrong arguments or not enough of them. * <https://hackage.haskell.org/package/text-format text-format> takes a formatting string with curly braces denoting places where arguments would be substituted (the arguments themselves are provided via a tuple). If you want to apply formatting to some of the arguments, you have to use one of the provided formatters. Like 'printf', it can fail at runtime, but at least the formatters are first-class (and you can add new ones). * <https://hackage.haskell.org/package/formatting formatting> takes a formatting template consisting of pieces of strings interleaved with formatters; this ensures that arguments always match their placeholders. 'formatting' provides lots of formatters and generally seems to be the most popular formatting library here. Unfortunately, at least in my experience writing new formatters can be awkward and people sometimes have troubles understanding how 'formatting' works. * <https://hackage.haskell.org/package/fmt fmt> (i.e. this library) provides formatters that are ordinary functions, and a bunch of operators for concatenating formatted strings; those operators also do automatic conversion. There are some convenience formatters which aren't present in 'formatting' (like ones for formatting maps, lists, converting to base64, etc). Some find the operator syntax annoying, while others like it.
