Tools for Thor: PEM Editor w/IDE Tools,   The Thor Repository,   GoFish4


  • has a user interface to control the assignment of hot keys to tools and developer-defined menus. The UI provides four different methods for accessing these tools:
    1. By assigning hot keys to them
    2. By creating pop-up menus accessible via hot keys
    3. By adding them as bars under any of the VFP system pads (File, Edit, View, etc.)
    4. By creating new pads in the VFP system menu and adding them as bars under these new pads
  • provides a unified method for registering tools.
  • simplifies the task of sharing them between developers.

Thor comes with a ready-made list of tools from two sources, the Thor Repository and PEM Editor. (See below)

Unlike the normal limited set of hot keys available from ON KEY LABEL, Thor provides for the full range of multiple-keystroke combinations ({Ctrl + Alt + A}, for instance).

The 'tools' managed by Thor are simply PRGs with the following characteristics

  • The PRGs are named Thor_Tool_*.PRG
  • The PRG must be saved anywhere in the path, or in one of two Tools folders (which are created at installation) -- one for downloaded tools, one for personal tools.
  • The first 40 lines or so of the PRG must follow a fixed template, allowing Thor to query them as to their name, description, etc.

The Thor Repository

Inherent in the design of Thor is the anticipation that members of the FoxPro community will have utilities of value that can well be shared throughout the community. The structure of the tool PRGs make such sharing simple.

The 'Thor Repository' is a catalog of such tools. The intent is that this repository grow over time, as developers submit tools to be included. The starting repository has about a dozen such tools. Click here for the help page for  The Thor Repository

Downloading and installation of the Thor Repository occurs automatically as part of the One-Click Update for Thor

IDE Tools from PEM Editor

Version 7 of PEM Editor, now re-named 'PEM Editor w/ IDE Tools', contains more than three dozen tools that can be accessed through Thor. These include some tools released in version 6 of PEM Editor, along with a large number of completely new tools. These can be downloaded from the PEM Editor page. Click here for the help page for Help page for PEM Editor w/IDE Tools

PEM Editor also "publishes" a pair of objects that simplify building further tools. More than half of the original tools in the Thor Repository use these objects.

Downloading and installation of PEM Editor 7 with IDE Tools occurs automatically as part of the One-Click Update for Thor.


Two new menu pads in VFP system menu (Thor and personal menu JRN) and the menu options in the Thor menu.



What's New

Thor 1.40 – Released 2013-08-26

Added the Thor ToolBar.  Tools may be added to the Toolbar may using the checkbox shown in the Thor Configuration form,  below (and also available in the Tool Launcher.)


When you add a tool to the Thor Toolbar, you can select a caption for the tool or select an image to represent it.  In the sample below, abbreviated captions are used.


The toolbar’s size, positioning, and docking, persist from one session to the next. (Truth be told, persisting the docking has been problematic.)

Thor 1.30 – Released 2012-08-19

  • Added Tool Launcher, available from the Thor menu in the VFP system menu

i just downloaded and installed Thor 1.40. When I do a Check for Updates, I never see the Thor Update Status dialog, but the Updates folder is populated with a bunch of prgs. Also when I do a Manage Plug-Ins I get a Program Error messagebox with LOTHORINFO is not an object

Mike -- I did not see your comments here until today. Thank you very much for your kind comments! See you in a couple of days!

I have a number of homegrown tools, as well as numerous third-party tools that I use in my development environment. When I first heard of Thor, I thought, Wow, what a great way to manage all that. I didn't download it right away, but only because I was busy and I was afraid I would spend a lot of time exploring its features and adding things to it. Well, I finally installed it, and "Wow" just does not do it justice. This is a "Mega-Wow"! Not only does Thor make it easy to hook in and manage any IDE tool you are currently using, but if you install PEM Editor for Thor and the Thor Repository, you get a whole suite of really useful stuff. I've been using PEM Editor for a long time, so I knew there were a lot of little gems in there, but it wasn't always convenient to get at them. Thor solves that problem, and then some. Plus, if you create a tool for Thor that you think will useful to others, even something really small, Thor makes it ridiculously easy to share what you create. It is my opinion that this is the most universally useful add-on ever created for VFP. I can't say enough about it here to do it justice. Don't wait to get it like I did -- get it now! You won't regret it. If you are fortunate enough to be attending SW Fox this year, be sure and attend Jim's sessions for a personal tour of Thor and its tools.

Kudos to Jim and everyone else who contributed to this project. Awesome job!
