A new release of OCamlODBC is available from the OCamlODBC web site: http://home.gna.org/ocamlodbc/ OCamlODBC offers bindings to various ODBC drivers. * Changes: column values of record are now of type string option to distinguish between "no value" and the "NULL" string. The TINYINT type is now recognized. * Fix: a bug which resulted in truncated fields and so incorrect values. Thanks to Christophe Troestler for this contributions. The toy application Biniki now uses LablGtk2. Examples and Biniki were fixed according to the small change in interface.

The widgets supported in camltk/labltk are those of tk8.0. New widgets were not added to keep compatibility, but since Tcl/Tk seems to have finally converged on 8.4, this might be a good idea to add the new widgets now. This is easy to do: mainly editing the Widgets.src file. But this is time consuming: one has to check by hand the Tcl/Tk documentation to find all the missing functions and parameters... So this will probably not be in 3.10.0, but could be done in a reasonably close future. > Is there any plan to upgrading 'labltk'? > Should I use 'lablgtk2' or something instead of 'labltk'? Use the one that fits your needs. There are more widgets in gtk2, but they can be harder to use.Jacques Garrigue then asked and Jacques Garrigue answered:
> Let me ask another question. > # Maybe it's a FAQ... > Why camltk and labltk both exists? > These look like twins for me. > What is the role of these two libraries? > (I think if there is no need to use the camltk...) The original library was CamlTk, and LablTk was actually created by hacking the automatic generation tool included in CamlTk. As a result, for a long time only CamlTk was available, and for instance the MMM web browser was developped using CamlTk. Many examples are available, and CamlTk is described in one of the rare books on OCaml written in English. For all these reasons, it is necessary to continue supporting it, and the current implementation does it at a very low cost, by using the same backend.

ocamlscript version 2.0.0 was just released. It is considered stable, and there is no big change since the previous release 1.99.5 except for the packaging and the web page: http://martin.jambon.free.fr/ocamlscript.html Ocamlscript 2 derives from David Mentre's original implementation and adds support for findlib packages, camlp4 syntax extensions, ocamllex, ocamllyacc, input from stdin, script on the command-line, and some support for compilation and linking with other source files. In theory it can also be configured to support any compiled programming language other than OCaml. Description: =========== ocamlscript compiles scripts, i.e. one-file programs, into natively-compiled binaries, and executes them. Basically, a script named alpha is compiled into alpha.exe. If alpha.exe is more recent than alpha, then alpha.exe is executed directly, otherwise alpha is recompiled first. Compilation commands reside in the first section of the script. They are written in OCaml and consist normally in setting one or two variables. Example: ======== The following "getpage" script fetches a web page using the HTTP client provided by the netclient library/findlib package: #! /usr/bin/env ocamlscript Ocaml.packs := [ "netclient" ] -- match Sys.argv with [| _; url |] -> print_string (Http_client.Convenience.http_get url) | _ -> prerr_string "Usage: getpage URL\n"; exit 1 For instance, executing "getpage http://caml.inria.fr" creates a getpage.exe file in the same directory as "getpage", runs it and prints the web page that was requested.
