Changelog

Switch to snake_case function names. The camelCase version are still there for backward compatibility.

The package now store temporary data in SciViews:TempEnv instead of TempEnv and it needs {svMisc} >= 0.9-68.

R 2.15.0 complains about argument partial match in print.gui(): guiAsk(gui = x). Fixed.

Large refactoring of SciViews-R packages. Most of the functions to interface with Komodo are moved to the ‘svKomodo’ package: koCmd(), guiInstall(), guiUninstall(), guiRefresh(), guiAutoRefresh(). The functions dealing with the httpServer are moved to ‘svHttp’: parHttp(), startHttpServer(), stopHttpServer(), HttpServerPort, HttpServerName() & HttpClientsNames(). So… basically, nothing much left here from previous version! But now it contains functions to manage ‘gui’ objects, used by ‘svWidgets’ and ‘svDialogs’.
S3 objects of class ‘gui’ are added. They are supposed to be created by guiAdd() and a series of functions is provided to manipulate them. They are not terribly useful by themselves, but they provide the foundation for a flexible organization of GUI elements in R (see for instance ‘svDialogs’ or ‘svWidgets’).

HTTP server now works with the new version of captureAll() from ‘svMisc’ 0.9-62 and it is compatible with its echo = and split = arguments.

HTTP server code processing now uses parseText() of {svMisc} >= 0.9-60 instead of the deprecated Parse() function.

koCmd() now should prepend <<<js>>> to the JavaScript code to get it evaluated in Komodo (starting with SciViews-K 0.9-18). Komodo now also accepts RJsonP strings, prepended with <<<rjson>>>. If there is no code prepended to the string send to Komodo, it is just printed in the local R console. A new ‘type’ argument specifies what kind of string we send to Komodo.
The R http server is modified to work with either RJsonP calls, or with plain text exchange, as the SciViews socket server works. RJsonP objects returned use list() to create lists, but also structures or new S4 objects.

A new series of function to communication with a SciViews GUI client like Komodo/SciViews-K by using the R http help server is added. It offers a tcltk-free alternative to the ‘svSocket’ server.
The package no longer starts the socket server implemented in ‘svSocket’ and it does not import ‘svSocket’ any more. As the HTTP server is an alternative, one could now choose to run SciViews communication through the HTTP server without using ‘svSocket’, and thus, without starting Tcl/Tk any more.

Use of svTaskCallbackManager() of ‘svSocket’ >= 0.9-48 to register task callback that are also executed after each R code send by socket clients.
guiRefresh() now clears active items and MRU lists in Komodo for non-defined active data frames and ‘lm’ objects.

Added guiRefresh() and guiAutoRefresh() to refresh automatically the content of the GUI (Komodo) object explorer and the lists of active objects.

koCmd() is now more robust and do not issue a warning or an error if the Komodo server is not available (but the error message is returned by the function with a ‘try-error’ class, so that it can be processed by the caller) .

Correction of a bug in the first example of koCmd().
guiInstall() now creates a hook to koCmd(): .koCmd() in SciViews:TempEnv.

This is the first version distributed on R-forge. It is completely refactored from older versions (on CRAN since 2003) to make it run with SciViews-K and Komodo Edit (Tinn-R is also supported, but not SciViews-R Console any more).
