flat VS text

Now we have Generically(1) in base (since 4.17) so any class with generic default methods can have an instance of Generically. I made an issue: https://github.com/Quid2/flat/issues/33

Version 0.6 of Flat, a principled, portable and compact binary data format is on Hackage.

Here is link number 1 - Previous text "one"

String is a linked list of UTF-32 codepoints, which is just as bad as it sounds. Haskell programmers usually use Text from the text package instead.

This is the first release that was executed via the new GitHub CI. Everything went smoothly, except for an unexpected packaging bug on windows due to text-2.0 linking against libstdc++ by default.

In addition to what's mentioned, the "default" libraries people use are often not the best-performing ones. E.g. Data.Vector.Hashtables is often much faster than Data.HashMap.Strict (which again is typically faster than Data.Map). And we find performance papercuts in common libraries that may simply be due to not enough people optimising for speed.

Used by nearly every Haskell project: https://hackage.haskell.org/package/text 60% of the modules are ".Internal".

Here is a representative patch for text: https://github.com/haskell/text/pull/365/commits/37a2157245457a287d638bbceb472fe93b71f224 Hopefully it clarifies why achieving C performance is problematic even if you have enough primitive operations.

I want to run an app in a Docker container, but detached. This causes getLine to throw an EOF exception, since the terminal detaches. That is, if I understand this thread correctly https://github.com/haskell/text/issues/258.
