This is our pleasure to announce The Objective Label Trilogy, version 1.04 Objective Label / LablTk / LablBrowser Objective Label is an extension of Objective Caml with labeled and optional arguments, and polymorphic variants. LablTk uses these extensions to provide an almost type safe interface to Tcl/Tk, such that you can write application in a style very close to Tk. LablBrowser is a programming environment, allowing one to browse code, both source and compiled, and navigate through it on the basis of types and compiled interfaces. It also includes an editor, and a language shell. The combination of these three elements is a system * easy to program, thanks to the libraries and tools * producing more readable programs, thanks to labels * allowing preciser and lighter typing, thanks to variants The port is complete: all the functionality and tools of Objective Caml is available. It is source compatible with O'Caml: any program or library written in O'Caml can be compiled without modification, and you may even add labels to interfaces to your taste. This release should work on any Unix/X windows based system, producing native code on architectures supported by Objective Caml. It may also work on Windows NT, but this is not supported at this time. A binary version, centered on LablBrowser, should be available soon for Windows systems. Changed from 1.03: This release was a little bit late, because there were many changes to merge on both sides. O'Labl: * easier to install: no need to bootstrap. * variant syntax is extended (types and matching), and they are now fully recursive. Powerful subtyping mechanism, similar to objects * they are better compiled (optimized match compiler, and profits from the changes in the native code compiler) * updated the manual :-) LablTk41: * now based on OCamlTk41. You will need Tcl/Tk 7.5/4.1 or 7.6/4.2. * corrected some strange definitions LablBrowser: * changed completely the layout of the browser, which should be much easier to use * many new browsing and navigation functions: you may now jump from interfaces to source code, etc... * added a shell to run a toplevel You may get the O'Labl trilogy at http://wwwfun.kurims.kyoto-u.ac.jp/soft/olabl/ ftp://ftp.kurims.kyoto-u.ac.jp/pub/lang/olabl/olabl-1.04.tar.gz Comments to Jacques Garrigue <garrigue@kurims.kyoto-u.ac.jp> Jun Furuse (LablTk) <Jun.Furuse@inria.fr>
