J Wiki Organization

This wiki is organized functionally which means that the areas are separated into sections according to how different users would like to use them. The Newcomers section provides a view into different parts of the wiki in a way that would be most useful to those who are new to J. The Reference section provides every bit of J knowledge in the wiki. Be warned that this includes some information that is no longer supported, but still may be of use for research or historic purposes. The Community section has links to information both inside and outside of this wiki ranging from Journals and Blogs to User Groups and Live channels.

J Wiki Navigation

Category Trees

This wiki is organized by Category Trees. The main tree's root is the Home category, accessed through both the Sidebar and the Category Table located at the bottom of each page. Any category becomes a category tree when it has subcategories that link to it. Think of category trees as windows into the J wiki. Depending on the category, sub-categories will have different views of the wiki information. The "Essays" sub-category in Newcomers is very different from the "Essays" subcategory in Reference. In the future more category trees could be added to provide the specialized views that J wiki users feel are important.

The Sidebar

The sidebar on the wiki page is probably the most useful navigation tool outside of the Category Table. The side bar exists on every page of the wiki and is always accessible.

The Category Table

The Category Table is located towards the bottom of each wiki page has a link for all the categories in J Wiki's category tree. The Category Table exists on every page of the wiki. The major subcategories are grouped by colour and the font-size decreases as you move away from the tree's root.

J Code Search bar

The J Code Search bar, located in the upper right above the wiki content, provides one click access to both the NuVoc Dictionary and the J Code Search for which it is named.


NuVoc NuVoc is a user maintained dictionary for the J language. It supercedes the previous J Dictionary and Vocabulary and is considered the most up to date reference to the language.
J Code Search The J Code Search is a custom search built by Chris Burke that allows the J primitives to be searched. The traditonal wiki search regards many of these primitives as punctuation. It also allows regular expressions to be used to refine the search results.


Keeping Track of Useful Pages

The easiest way to track pages that are most useful is to bookmark them in your browser for quick access. We are hoping that these bookmarks may be curated and added to the User's page, as sharing this information could be very useful for discovering best practices of J Wiki navigation. Every person who is able to log in to the J Wiki has a User page that is initially blank, but can be populated by either personal projects, bookmarks or information.

The J Viewer

If you are using the JQt IDE, Ed Gottsman's "J Viewer" is an invaluable tool. It provides access to searches of the J Wiki, the GitHub repository, Rosetta Code, Quora and the J forums. If you are not using it, why are you not using it?
