Welcome to blaze-textual

blaze-textual is a fast Haskell library for rendering common Haskell datatypes in text form using the blaze-builder library.

Important note for users of GHCi and Template Haskell

To achieve excellent performance for rendering floating point numbers, this package uses the double-conversion package.

Unfortunately, due to bugs in GHC, some uses of GHCi and Template Haskell can crash if this package is loaded.

If you are affected by these problems, you should expect the 5289 crash to look like this:

Loading package double-conversion-0.2.0.0 ... can't load .so/.DLL for: stdc++

The 5386 crash causes GHCi to die with a floating point exception (SIGFPE).

To work around these bugs, this package includes an alternative, slower, floating point conversion that is written in pure Haskell. Because it is 10 times slower than the double-conversion package, it is not the default.

To use it, reinstall this package by passing the native flag to cabal:

cabal install -fnative

Afterwards, you will also need to reinstall any downstream packages that depend on this one, e.g. the aeson JSON library:

cabal install aeson --reinstall
