Version 20 of Wikit

The name "Wikit" can be interpreted in two ways:

An implementation of Wiki in Tcl
An implementation of Wiki using MetaKit.

Both are accurate.

Wikit can be used as a CGI process (see Wikit under CGI), in which case it becomes a part of your web server, or it can be used standalone, running locally with a Tcl/Tk graphical front end (see Wikit in local mode). The former makes collaborative editing possible, the latter includes a high-performance search facility and makes it very easy to browse and edit information off-line.

Right now, these two mechanisms do not mix.

What you can do, however, is download a copy of an active web-based WiKit (such as this one, the Tcl'ers Wiki), and keep it around as reference to what that snapshot contains. WiKit is fully self contained in a single platform-independent file, called a scripted document. It requires a platform-dependent runtime called Tclkit, There are runtimes for over a dozen platforms.

Furthermore, as of 2002, Wikit can be embedded as a hyperlinked and searchable help system.

Searching and bookmarking URLs on the Tcl'ers Wiki covers the topic of using WiKit's built in search functionality; the page really did not need to mention Tcl'ers Wiki since it is general functionality of Wiki.

Wikit is way cool.

The following procedure can be used to add gif image files to a stand alone wikit database (i.e. .tkd file).

Assumptions

a directory named dir exist
a wikit database named wikit.tkd is in the directory
a gif image file named image.gif is in the directory

Procedure

Open the wikit database using wikit.kit application.
Edit the page where the image is to added and add the following text [http://image.gif] where the image is to appear.
Save the changes to the page and exit wikit
Run the following command in the dir directory.

    % tclkit wikit.kit -images scan wikit.tkd
    Scanning 17 wiki pages...
    1 urls added, 0 urls deleted

Then run this command in the dir directory.

    % tclkit wikit.kit -images local wikit.tkd
    1 local images copied

The image is now loaded into the wikit database (so try it out :-)

-image options

tclkit wikit.kit -images scan wikit.tkd: Scans all pages, updating an "image cache" inside the wikit.tkd datafile (this does not fetch images, it just updates that cache) repeated calls are incremental: adds new / deletes unused items
tclkit wikit.kit -images list wikit.tkd: Lists all entries currently in the image cache, with fetch/file dates
tclkit wikit.kit -images get wikit.tkd: This goes through the image cache and fetches any entries which have not been successfully fetched before (only images <= 100 Kb)
tclkit wikit.kit -images local wikit.tkd: Goes through caches, storing all images it can find in [pwd], i.e. updates and replaces what is in the cache with local file copies (can be used to add/replace, and to store images > 100 Kb)
tclkit wikit.kit -images clear wikit.tkd: Clear the image cache (does not compact the wikit datafile, but space will be re-use
