I've been working on overhauling VTY for: * variable column unicode text rendering * improved performance * improved terminal support * More flexible image combinators.
While there are a number of tasks still remaining before a release, the infrastructure is all in place. I've also completed an initial version of an interactive test that can be used by a user to create a report about how well VTY supports their terminal. I would like anybody willing with about 10 minutes to spare to run this test and email me the results. To run the interactive test it's necessary to: 0. Pull the latest VTY from http://code.haskell.org/vty/ 1. Open their terminal of choice to the "test" directory in the vty sources. 2. execute "make interactive_terminal_test" 3. Assuming the source builds OK (It does not use Cabal so building the test can be unreliable) the test should walk you through the verification process. I'm pretty sure I know what the results are going to be for the various terminals. ;-) However I would still like people to run the test to work out any kinks in the test process and establish a nice baseline data set. For those that are curious what modules are used for terminal support: Graphics.Vty.Terminal: This instantiates an instance of an interface to the terminal. Currently this always instantiates the XTermColor terminal interface. This should instantiate a terminal interface based on the TERM environment variable. Graphics.Vty.Terminal.Generic: Defines the generic interface all terminals need to implement. Graphics.Vty.Terminal.XTermColor: This module contains an interface suitable for xterm only due to the many hard coded control codes. This does use terminfo for some control codes. This would be a useful reference for building new terminal support modules. The work remaining: 0. Add more terminal support instances (In particular a generic one that just relies on termcap) 1. The interface exported by the package still uses the old implementation. 2. Resolve performance regressions.
