There is a bugfix release 1.3.2 now, that fixes several errors from 1.3. Including the  one that occured when File->new was called and one tried to edit the new file before saving. Get the update here.

Version 1.3 of Tloona Tcl/Tk IDE is out. Here are the highlights for this release:

• various bugfixes
• client console is able to read stdin now
• code browser understands XOTcl meta classes and slots (via the -slot argument)
• code definitions can be sent to the client console: proc, method (Itcl), instproc, class proc, Class, meta Class (XOTcl) with <Control-Return>

The latter makes it a pleasure to test your programs and procedures while you are developing them. Just load the program into the client console, then edit the procedures, classes etc. and repeatedly send them to the console with <Control-Return>. You can immediately try out what you have edited… this makes you even more productive!

There is a new screenshot, showing how Tloona is running Tclhttpd inside it’s client console. Combined with the ability to send code definitions to the console and the debugging options this is a very pleasant way to develop and test web applications rapidly.

There is another goodie on this project site now. Tclmatlab is an extension to connect Tcl to MATLAB, the powerful platform for numerical and technical computing. It allows Tcl programmers to use the capability of MATLAB (http://www.mathworks.com/) and its numerous toolboxes.

The release enables Tcl programmers to transfer data to and from MATLAB using cell- and data arrays and to evaluate MATLAB scripts and functions via the Engine interface. It is also possible to use MATLABs strong visualization capabilities.

In addition there is a new page on this website to describe how to work with tclmatlab. It is a copy of the manpage that is part of the release.

As announced before, there is a new release 1.2.1 of Tloona.

This is merely a bugfix release, there are no new features. It gives some polish to the application, removing non-working functionality (see the last post on debugging for an explanation) and fixes lots of small, nitty-gritty bugs and annoyances.

The console got the most fixes and also a slightly enhanced functionality - it is now able to handle stdin. This means e.g. that you can run code with the debugger’s [bp] procedure inserted (see last post) inside the console as well as on outside terminals.

My special New Years present to the Tcl community (since I had some time over Christmas): A new release of Tloona… 1.2.

Quite some things have changed:

New parser functionality for XOTcl and Websh. This enables XOTcl developers and Websh developers to use the code browser for exploring their projects. Until now only tcl, html and Itcl/Itk were supported.

Currently no threads usage. The use of threads in previous releases has lead to crashes on multicore machines and was not quite stable. It needs to be designed a little better… currently it is disabled at all, until the redesign is done. I don’t know when/whether this will happen - depends on time. Help is appreciated!

Compatible to use standard Tcl and standard Itcl now. This does make sense - and decreases maintenance work ;-).

Tloona does not longer include external dependencies. Thus, this release is much smaller than previous ones. Extensions like comm, Tclx, Thread, vfs, starkit and others have been part of Tloona in previous releases but are not anymore, which also decreases maintenance work. It just means that users must take care of the extension installation by themselves now. The easiest way is to do this via teacup (part of the -very good- ActiveTcl distribution). But it can be done on other ways too… Eventually most of the dependencies are installed on your system already.

Release as starkit is dropped. This is related to the other dependency issue above. In previous releases, Tloona required a threaded Tclkit and since these are not available by default, I had to build and provide my own threaded Tclkits. This is evtl. continued, but it should not be a requirement for Tloona. Instead of running Tloona via tclkick, you can now use any Tcl installation (best: ActiveTcl) to run the IDE. Of course you are free to build your own starkits from Tloona and run them via Tclkick or other Threads enabled Tclkit. The standard release is now provided as a .zip file. Inside Tloona you can still distribute as starkit, but you need JCW’s SDX now - which you can get here.

How to install and run Tloona 1.2:

• download the release from here and unzip it.
• if you don’t have Tcl already, get and install ActiveTcl 8.5.
• in the unzipped release directory you find a file install_dependencies.tcl. Run it via tclsh - it utilizes teacup to fetch and install all necessary extensions. If you don’t have ActiveTcl/teacup, the file includes a list of dependencies that you must install manually.
• locate the directory of your Itk installation, if you installed Itk via teacup. It is usually $teapot/repository/package/$arch/lib/Itk-3.4, where $teapot is the base directory for teapot, e.g. “$home/.teapot” on Linux, and $arch is the architecture, e.g. “macosx-universal” on Mac OSX
• copy the files from tloona.vfs/itk_files/ into the Itk installation directory of teacup. It is a bug of Itk in teapot that these files are missin.
• Remove the preferences file .tloonarc from your home directory (C:\Documents and settings\user on windows). This has changed in this release.
• Run “tclsh tloona.vfs/main.tcl”. It will tell you at startup if something is wrong or still missing

Have fun and a Happy New Year :-)!
