This is my attempt at a means of making Therion work well with Windows. It has worked for me since early 2008 on various versions of Windows XP. I have had problems running Loch with Vista and am not sure why, but don't think it's related to the topic discussed herein.
Feel free to edit, comment or make suggestions on this page.
These pages do not describe 'the official word' on Therion. For that you should refer to The Therion Book, or pages on this wiki by those more knowledgeable. This is just my attempt to tame the beast, or a least understand it a little so that I can keep it under control.
To start with you need to download and install the package intended for Windows, not the Mac, Linux or other packages. Make sure you get the full installation and install it before considering installing the updates or so called ‘unstable’ versions. Therion does not appear to entirely follow Windows operating system norms, so there are a number of things that work a bit differently.
Similarly to Windows, XTherion (the user interface part of Therion) uses file extensions to decide whether to open a data file in the Therion Text Editor (*.th) or in the Therion Map Editor (*.th2) by default. All other files are assumed to be configuration files, but unlike Windows, because Therion convention is not to use extensions for configuration files, they cannot be opened easily directly from the Windows File Explorer interface.
To make it more Windows friendly I’ve adopted the .thc extension for ‘therion configuration’ files. To get windows to recognise these as belonging to Therion, double-click on a *.thc file, and assign it to the Wish Application in the list of available applications. The Wish Application is, I think, a tcl shell which manages the Therion application components. http://www.tcl.tk/man/tcl8.4/UserCmd/wish.htm
Now when you double-click on a file with a .thc file extension, Therion will generally open it in the Therion Text Editor, unless the file name starts with thconfig- in which case it will open it in the Therion Compiler. Yes, a bit odd, but it works out OK, so long as you only use the prefix thconfig- for configuration files that are intended to compile and produce output (as compared to configuration files that contain only formatting such as layouts to control for example paper size or the look of an output – these will open in the Therion Text Editor)
This all seems to work OK on Windows XP. I'm not sure about Vista. The Wish Application crashes when I have used it with Winows 7.
The above will get you going using Therion and the XTherion Interactive Editor. For a number of functions XTherion IS the best way of creating and editing Therion data files. (drawing, interactive data entry, viewing and entering file names and paths for surveys and maps, locating errors) Most of the time however, I have found that other generic text editors make creating and editing the various data files MUCH easier. I expect this is the case regardless of the operating system you use.
An application I like is described in NotePad++
