Low level Haskell bindings to the BearLibTerminal graphics library.

bearlibterminal-hs

Low-level Haskell bindings to the BearLibTerminal graphics library, primarily for roguelike games.

Description

Getting Started

Installing

• This library assumes you have built the main BearLibTerminal library (or downloaded the precompiled binaries) and your build tool can find it (e.g. by setting LD_LIBRARY_PATH or DYLD_LIBRARY_PATH).
• Add bearlibterminal to your *.cabal build-depends.
• Enjoy.

How can I do things?

This is pretty much a 1-to-1 mapping of the original BLT API, with some marshalling of types and wrappers around function calls that take C strings (these are offered in CString, Text, and ByteString flavours).

Every API call is available as both a raw FFI call (c_terminal_snake_case) and as a monadic MonadIO m => ... m a function.

Other notes:

• Colours are still simply 4-byte Word32s. Higher level colour functions are available in roguefunctor.
• terminalComposition takes a TerminalCompositionMode rather than raw integers.
• Events read by terminal_peek, terminal_read are returned as raw integers (terminalPeekCode) and as Events (terminalPeek).

This is a bit too low level for me...

Check out the Haskell roguelike toolkit library roguefunctor, which is the high-level, opinionated wrapper around this library with nicer abstractions for positions, colours, config options, event handling, rendering, and so forth.
